Heat Pipe Technology

High-Power Heat Pipe Technologies

 Therma-Charge™ uses standard heat pipes embedded in a metal plate and extending from the plates to a remote fin stack, where heat is rejected by natural or forced convection. These assemblies are typically used for cooling power semiconductors in motor drive assemblies and other applications.

 Isolated Therma-Charge™ units are designed for electrical isolation and can insulate several thousand volts of electricity. Different sizes and configurations of the Therma-Charge™ and Isolated Therma-Charge™ along with custom solutions are available.

Tower Heat Pipe Technology

 In a Therma-Tower™ the base plays an integral role. A significant thermal interface between the heat source and the air is eliminated due to the base’s wick structure, allowing higher heat flux loads to be handled. The vertical fin stack along the outside of the heat pipe results in maximum heat dissipation with the smallest footprint.

Embedded Heat Pipe Technology

  Embedding heat pipes into a heat sink is an effective cooling alternative, enhancing the performance of existing heat sinks with minimal design changes. Inserting heat pipes into grooves in a heat sink base can reduce a heat sink’s thermal resistance up to 50%.

Loop Thermosyphon Technology

 Therma-Loop™ is a loop heat pipe which contains no wick structure in the liquid and vapor lines. In its simplest configuration, the Therma-Loop™ is gravity aided and has no wick structure. This technology is utilized where length from the heat source to the condenser is not feasible for conventional heat pipes.

Vapor Chamber Technology

Therma-Base™ is a vapor spreader used as the base of a heat sink. A Therma-Base™ delivers higher performance than a traditional heat sink by alleviating spreading resistance typically found in solid heat sinks. The Therma-Base™ has an enhanced capability to accept higher heat fluxes than a traditional aluminum or copper surface. Additionally, its smaller size improves system packaging and provides quieter operation, at a reduced weight.
