❄ HELIOSYNC HX-3: Heat-Exchanger Cooling Assembly Exploded in 3D

About this simulation

Inside the HELIOSYNC HX-3: A Piece-by-Piece Guide to Liquid Cooling

A high-performance computer has a surprisingly demanding thermal problem. Central processors and graphics processors consume electricity, perform computation, and release much of that energy as heat. If heat is not transported from the electronic package to the surrounding air efficiently, component temperatures can rise, potentially limiting performance or damaging hardware. A liquid-cooling loop approaches this challenge as an integrated transport system. Heat passes from a processor into a metallic cold plate, enters a circulating coolant, travels to a radiator and leaves the system through moving air.

HELIOSYNC HX-3 is an original fictional liquid-cooling laboratory demonstrator made for MySimulator.uk. Its exposed hardware is intentionally arranged for education rather than to represent a commercially certified, leak-tested product. The assembly contains 174 individually identifiable mechanical and electronic elements. Seven groups contain articulated parts: three fan rotors, a centrifugal pump impeller, a flow-meter rotor, a pressure-gauge pointer and a service valve handle. The interactive viewer lets you examine these relationships from all directions, detach parts, explore five native GLB models, and reassemble a selected set by satisfying installation dependencies.

What you are looking at

At the top of the frame is a flat-tube radiator with metallic header tanks and a repeated fin bank. Three axial fans are arranged over its face. The radiator transfers heat from the moving coolant into the metal tube and fin network. The fins increase the metal-air contact area; the fans improve heat transfer by moving air over that surface. The two phenomena work together: more cooling surface helps little if the air around it becomes stagnant, and high fan speed cannot compensate for completely obstructed coolant flow.

A tall transparent reservoir appears to the right of the assembly. The reservoir acts as a visible liquid volume and helps explain filling, air removal and changes in coolant level. Beneath it is a pump module with an internal impeller and stator housing. A pump does not create 'cold'; it provides the pressure difference required to overcome resistance in tubing, fittings, the radiator and the cold plate. The pressure capability and achievable flow depend on the pump and the resistance of the complete hydraulic circuit.

The thermal receiving component is the copper cold plate in the lower-left module. A flat spreader conducts heat from the source. Closely spaced channels increase contact between liquid and conductive metal. In a real product, these channels are engineered to balance hydraulic restriction, clogging risk, manufacturability and heat-transfer performance. The top cover and gasket form the liquid distribution cavity. Screws apply clamping force to a seal; their locations and installation order matter because uneven compression can produce leaks.

The blue-coloured tube geometry makes the circulation path easy to follow. Copper fittings join the tubing to ports at the radiator, reservoir, cold plate and service modules. Sensors on the lower rail show how pressure and throughput can be monitored. The simulated readouts are illustrative model controls, not calibrated measurements or a thermodynamic solver.

Exploded assembly: understanding the hidden construction

A traditional product photograph hides the exact relationship between a fan rotor, its housing, mounting screws and the radiator it cools. An exploded assembly gives every removable part its own place while preserving the connection between parts. HELIOSYNC HX-3 begins with a structural datum: the frame, rails and mounting feet. These are fixed references. Internal components then separate according to assembly paths, while exterior grilles, covers and caps move outward to reveal the layers beneath them.

The explosion slider blends continuously from assembled to separated positions. A part is never moved to an arbitrary random location; its disassembly vector is chosen from plausible directions of access, clearance and installation. Rotor assemblies move forward from their fan shrouds, header fittings move along their connecting axes, upper caps separate from reservoir openings, and the cold-plate cover lifts away from the microchannel region. Because every part has its own original and exploded transform, moving the slider back to zero restores the exact geometry datum.

An exploded diagram communicates relationships, not manufacturing instructions. Real disassembly may require removing power, depressurising a loop, draining coolant, using specified torque sequences and observing electrical safety procedures. None of these safety requirements can be established from this fictional demonstration.

Why a fan needs a frame and a real rotor

An axial cooling fan converts motor torque into airflow. Its impeller contains several curved blades whose sweep, angle and chord influence pressure rise, noise and efficiency. The HX-3 model uses nine genuinely triangulated curved blades connected to each of three central hubs. A separate frame supports the rotor and creates clearance. A protective grille prevents accidental contact while introducing a small amount of flow resistance.

In the viewer, fan blades rotate around the corresponding shaft axis. Use the RPM slider to change the rate. Slower playback is available for viewing individual mechanism geometry; the live operating sliders change kinematic rates, not the assembly animation speed. These are two different controls. The displayed rotation follows a deterministic equation, allowing animations to remain stable when stopped or replayed.

In a real PC cooling system, fan control is usually achieved by voltage or pulse-width modulation, with a tachometer signal used for feedback. A thermal controller may respond to CPU, GPU or coolant temperatures. Noise and acoustic resonances often increase at certain speeds, which is why maximum RPM is not necessarily the optimal everyday setting.

How the centrifugal pump drives coolant

A centrifugal pump contains a motor-driven impeller enclosed by a volute. The rotating vanes transfer angular momentum to liquid, causing it to move outward from the impeller centre. The casing guides this flow toward an outlet, converting some velocity into static pressure. A pump therefore needs appropriate inlet conditions and should not be run dry. The radiator and microchannels create pressure losses; the resulting operating point occurs where pump pressure capability meets hydraulic system resistance.

HX-3 exposes the pump casting, rear motor casing, inner impeller and front inspection cover. The seven-vane impeller has its own articulated node and can be selected individually. The transparent reservoir above it helps visitors understand the liquid supply and the importance of removing air. The visible blue passages are illustrative. They do not claim true turbulent flow, coolant cavitation or computational fluid dynamics.

Cold plate, fins and the heat-transfer chain

Three modes of heat transfer appear throughout the assembly: conduction through metal, convection between metal and fluid, and energy carried by a circulating mass of coolant. A useful idealised thermal relation is Q̇ = ṁ × cp × ΔT, where Q̇ is heat transfer rate, ṁ is mass flow rate, cp is specific heat capacity, and ΔT is the fluid temperature change across a component. This relation is a bookkeeping tool, not a full performance predictor. Accurate temperatures additionally require thermal contact resistance, losses, fan and pump curves, fluid properties and boundary conditions.

The heat spreader is copper-coloured because copper is commonly used for its high thermal conductivity. The radiator fins are lighter to distinguish surfaces optimised for air contact. Real products may use mixed materials and surface finishes; their compatibility depends on coolant chemistry, corrosion control and protective plating. Never treat the fictional colour scheme as a verified bill of materials.

Manual assembly: play the engineer

The manual assembly challenge begins with a set of parts moved away from their seats. Select a detached part in the scene or index, then drag it in screen-space to approach its original mounting location. A crosshair marks the seat, and a connecting guide line helps judge direction. Rotational correction uses Q and E, ten degrees per key press; keyboard axes support fine translation. Release a part sufficiently close to its reference transform to attempt a magnetic snap.

The simulator checks two independent constraints: a position error no greater than 0.34 display units and an orientation error no greater than 18 degrees. If a prerequisite part is missing, placement is rejected. These are gameplay thresholds in a normalised fictional model, not engineering manufacturing tolerances. The guidance system can show the next available component, but it will not automatically teleport an incorrectly positioned part into place.

Standard challenge difficulty contains twelve removed components; expert difficulty contains twenty-two. A timer, mistakes and progress are visible throughout play. The challenge is designed to teach the concept of a valid assembly order rather than imitate a professional service manual.

3D inspection techniques

Solid view shows all physical meshes. Exploded view spreads layers along their planned removal directions. X-ray view makes outer assemblies translucent so that inner parts remain visible. Cutaway uses a genuine WebGL section plane to discard a portion of intersected triangles and exposes an exported cutaway variant with selected covers removed. Wireframe mode displays real triangle edges. Ghost mode keeps unselected components translucent, and isolate mode removes unrelated subsystems from the display. Engineering mode shows a reference grid, datums and geometric visual-unit annotations.

Different inspection modes answer different questions. X-ray is useful when an internal component is still housed by a shell; cutaway reveals a cross-sectional arrangement; wireframe helps inspect the underlying generated geometry. None should be confused with destructive examination of an actual manufactured component.

Engineering trade-offs and realism

A reliable cooling design balances heat load, flow resistance, acoustics, size, weight, cost, serviceability and leakage risk. A larger radiator can provide additional surface area but requires more packaging space. Denser fins may improve available contact area while demanding stronger airflow. Tight cold-plate channels increase wetted metal surface but can introduce pressure drop. Pump speed may increase flow but also add electrical consumption, noise and fluid heating. Flexible hoses are simple to route but impose bend-radius and connector-stress constraints.

The fictional HX-3 is not intended to prove a particular thermal performance. Its purpose is to make these trade-offs visible and to connect each one to a tangible piece of geometry. The exported GLB assets use named nodes, material properties, actual triangles and separate animated mechanical elements so that the assembly can be examined in standard 3D workflows beyond this website.
