Product Details
The heat pipe heatsink is composed of sealing tube, suction core and steam channel. The core-pulling is enclosed in the wall of the sealing tube and saturates the saturated volatile liquid. The liquid can be distilled water, ammonia, methanol or acetone. The heat pipe heatsink filled with ammonia, methanol, acetone and other liquids still has good heat dissipation capacity at low temperature.
When the heat pipe heatsink runs, it's evaporating section absorbs the heat generated from the heat source (the power semiconductor device, etc.), making the liquid in the core boil into steam. The heated steam moves from the evaporating part of the heat pipe heatsink to the cooling part, where it condenses into a liquid. The condensed liquid returns to the evaporation section through the capillary action of the suction core on the wall, repeating the above continuous cooling cycle.
Heat pipe heatsink feature
● Heat pipe heat sink has fast thermal response speed, Its heat transfer capacity is more than 1,000 times greater than that of copper tubes of the same size and weight;
● Small size and light weight;
● High heat dissipation efficiency, can simplify the heat dissipation design of electronic equipment, such as variable air cooling for self-cooling;
● Heat pipe heat sink do not need external power supply, work without special maintenance;
● Has a good isothermal, thermal balance, the evaporation section and cooling section of the temperature gradient is quite small, can be approximately regarded as 0;
● Heat pipe heat sink is safe and reliable operation, does not pollute the environment.
Production Process
Copper pipe+zipper fin heat sink
The fins are welded, made of stamping material copper, and folded into a shape with interlocking slots.The folding fin can transfer high thermal energy and has more than 3000 different configurations.
Larger surface area, more flexible design and more stable structure than extruded fins, allowing very high fin density and length-width ratio, thus increasing surface area and better cooling. Zipper fins also increase design flexibility, especially for pipes that integrate heat pipes, fans, or blowers.
Product Application
Applied to Communication, UPS, inverter, controller, wind power converter, SVG telecommunication.
Copper Heat Pipe Heatsink Assembly For LED Application
Utilizing advanced thermal analysis techniques, we were able to develop a solution utilizing copper heat pipes embedded in the base of the heatsink to more effectively draw heat from the LEDs and distribute throughout the heatsink fins. The end result eliminates hot spots with even distribution of heat across all the plate fins.
