Quick Detail

Description

    Heat pipe radiator is a new product produced by using heat pipe technology to make major improvements to many old radiators or heat exchange products and systems. There are two types of heat pipe radiators: natural cooling and forced air cooling. The thermal resistance of air-cooled heat pipe radiator can be made smaller, and it is often used in high-power power supplies. 

Note

Production process

Aluminum fins: Pressing the aluminum plate to a stacked fins by high speed stamping machine;

Heat pipe: Filling the copper power and water into the copper tube and sealing the two ends;

Aluminum base: Extrusion and CNC machining;

Heat sink assembly: combining the components together to the fixture and then put into the reflow oven for soldering.

How much power can a heat sink dissipate?

The product of collector current and voltage either side of this quiescent state produces less power dissipation, so 45 W is the maximum power dissipation to consider. This value is used below to calculate the heat sink

How do I know what size heatsink to get?
Volumetric Thermal Resistance (Rv) – This equation and subsequent guidelines have been shown to closely estimate heat sink volume: V=(Q*Rv)/Delta T. The first step in using the chart below is to know the available airflow across the heat sink. As you know, the higher the airflow the smaller the heat sink.

The heat pipe radiator has the following advantages:

• The thermal response speed is fast, and its ability to transfer heat is more than 1000 times larger than that of copper pipes of the same size and weight;
• Small size and light weight;
• High heat dissipation efficiency, which can simplify the heat dissipation design of electronic equipment, such as changing air-cooling to self-cooling;
• No external power supply is required, and no special maintenance is required during work;
• It has good isothermal properties. After heat balance, the temperature gradient between the evaporation section and the cooling section is quite small, which can be approximately regarded as 0;
• The operation is safe and reliable, and does not pollute the environment.

We can offer the heat pipe radiator service, small qty is acceptable.

Technical Support

We can offer the design and simulation service. For example, our German customer's case.
