Problems solved by technology

However, due to the special requirements for the structure of the gravity heat pipe, when in use, the evaporation end of the gravity heat pipe must be placed at the lower part of the radiator, and the condensation end must be located at the upper part of the radiator. This arrangement greatly limits the application of the gravity heat pipe, especially It is unable to meet the installation requirements of power electronic devices for radiators

Abstract

The invention provides a phase change radiator. The phase change radiator comprises an evaporation part and a condensation part obliquely arranged on one side of the evaporation part, wherein the evaporation part and the condensation part communicate with each other and form a sealed chamber together, and a refrigerant is injected in the sealed chamber; the evaporation part comprises a vertical substrate and liquid absorption cores arranged on the substrate, first grooves are longitudinally formed in the upper part of the substrate, the liquid absorption cores are embedded in the first grooves, and the lower parts of the liquid absorption cores are immersed in the refrigerant; radiating fins are arranged in the condensation part, and the end, close to the evaporation part, of the condensation part is lower than the end, away from the evaporation part, of the condensation part. The radiator has the advantages of small occupied space, good homeothermy, short refrigerant phase change period and excellent radiation effect, and installation requirements of power electronic devices on the radiator can be met.

Description

technical field [0001] The invention relates to the technical field of heat dissipation, in particular to a phase change radiator. Background technique [0002] Power electronic devices, also known as power semiconductor devices, are mainly used in power conversion and control circuits of power equipment. The power loss of high-power power electronic devices will cause the power electronic devices to heat up and heat up, and if the device temperature is too high, it will shorten the life of the device or even burn the device. Therefore, the cooling problem of the power electronic device must be considered to ensure that the power electronic device is at the rated temperature. work within the range. At present, the commonly used method is to cool the power electronic devices through the radiator. The radiator has the function of conducting and releasing heat without hindering the normal use of the power electronic devices. [0003] Among the many types of radiators, phase c...
