Heat Pipe

A heat pipe is a device with phase-change principle to efficiently manage the heat transfer between two solid, or fluid interfaces.

At the evaporation area of a heat pipe, liquid in contact with a thermally conductive solid surface turns into a vapor by absorbing heat from that surface. The vapor then travels along the heat pipe to the cold interface and condenses back into a liquid - releasing the latent heat. The liquid then returns to the hot interface through and the cycle repeats.

Each heat pipe project has a particular operation temperature range, the thermal solution designer has to specifying the proper working fluid and pipe material by the intended application. The most common application is a copper pipe with water operating within a temperature range of 5°C to 150°C.

For low temperature application, Cooling House offers methanol heat pipes with copper or stainless pipes, when the heat pipes have to work below water range.

Methanol heat pipe

Methanol heat pipe can operate from -30°C to 90°C, available in standard diameters and it’s wick structure selection includes sintered powder, mesh and groove type. Compare to traditional H2O heat pipe, the working fluid doesn’t freeze at 0°C, which offers constantly heat transfer performance in the extreme ambition conditions.

Stainless heat pipe

The anti-corrosion capability of stainless pipe allows long-life thermal solution in harsh environment, the application can be outdoor air-to-air heat exchangers. The working fluid selection includes pure water and methanol, available in standard tube diameter, combination of stainless pipe and methanol offers the best non-freezing and anti-corrosion capability for extreme conditions.
