Heat Pipe Heat Sink

Heat pipe Heat sink is a new product which can improve many old radiator or heat exchange products and systems by using heat pipe technology. There are two kinds of heat pipe radiator: natural cooling and forced air cooling. It can be used in power electronics, IGBT, transformer, high-power power supply, LED lamps, servers, computers, medical products, etc.The heat pipe heat sink is composed of seal tube, wick and steam passage.When the heat pipe radiator is running, its evaporation section absorbs the heat generated by heat source (power semiconductor devices, etc.) and makes the liquid in the wick tube boil into steam. The steam with heat moves from the evaporation section of the heat pipe radiator to its cooling section. When the steam transfers heat to the cooling section, the steam condenses into liquid. The condensed liquid will return to the evaporation section through the capillary action of the wick on the pipe wall, so as to repeat the above circulation process and continuously dissipate heat.

1. Structural characteristics
It is not an integral extrusion, nor is it a simple scraping tooth
It is composed of multiple parts: bottom plate + dense fins + flow guide structure/liquid cooling cavity.
Fins and bottom plates are fixed by welding/brazing/buckling
The fins are thin, dense and tall, and the heat dissipation area is huge.
Can be made into air-cooled + water-cooled composite structure
Suitable for ultra-high power, high temperature, and space-limited scenarios.
2. Core advantages
Large heat dissipation area, and the heat dissipation capacity far exceeds that of ordinary aluminum extrusion/shovel teeth
Thin fins, high density, good balance between wind resistance and heat exchange efficiency
High structural strength, earthquake resistance and vibration resistance
It can be customized and can be made into special-shaped and high-power modules
Suitable for long-term stable operation of high-power-density equipment
3. Processing technology
Fin stamping/forming
CNC machining of base plate
Fin fastening/plugging/assembly
Vacuum brazing/furnace welding/laser welding
Polishing, stress-relieving, surface treatment
Airtightness/strength test
4. Typical applications
High-power power supply, inverter
New energy vehicle electronic control, motor
Energy storage converter PCS
laser equipment
RF/Microwave Power Amplifiers
Servers, GPUs, AI computing equipment
Industrial transmission, high-frequency equipment
