Description

A self-cooling heat pipe radiator

technical field

The utility model relates to the field of radiators, in particular to a self-cooling heat pipe radiator.

Background technique

With the development of power electronics technology, high-power power electronic devices are more and more widely used in power systems. For a long time, the heat dissipation of high-power power electronic devices has mainly relied on forced air cooling and forced water cooling, but the fan is a rotating device with a high failure rate and heavy maintenance workload; water cooling requires additional water cooling equipment. At the same time, both air cooling and water cooling require the introduction of an external power supply, but this equipment is used on a 500kV high-voltage platform, which cannot introduce a low-voltage power supply, and can only use "air self-cooling" for heat dissipation. The so-called "self-cooling" cooling is to take away the heat through the natural convection and radiation of the air. Although this kind of radiator has a simple structure, no noise, easy maintenance, and high reliability, its efficiency is low and cooling fins are often used. Therefore, it cannot fully meet the cooling requirements of high-power power electronic devices and also increases the size of the radiator. Therefore, there is an urgent need for a heat sink with low thermal resistance, high thermal capacity, and small volume to meet the requirements of absorbing power electronic components to generate energy in a short time.
