Embodiment 1
[0084] Below in conjunction with accompanying drawing and embodiment the present invention is described in detail:
[0085] Refer to Figure 4 for the forced water-cooling mode micro-groove group composite phase change integrated cooling rectifier cooling system. For the rectifier power electronic equipment composed of 6 high-power thyristor components, a thyristor device at the cold end of the forced water-cooling mode is produced. Microgroove group composite phase change integrated cooling system. It includes a vacuumized micro-groove group composite phase-change heat collector 2 for taking heat from the heat-generating surfaces on both sides of the thyristor 1 . Each thyristor 1 is provided with two micro-groove composite phase-change heat extractors 2, each taking heat from one side of the thyristor 1. The 6 thyristors 1 forming the thyristor rectifier cabinet device are provided with 12 micro-groove composite phase-change heat extractors 2 in total. Each microgroove grou...
Embodiment 2
[0090] Refer to Figure 5 for the forced air cooling mode micro-groove group compound phase change integrated cooling rectifier cabinet heat dissipation system, for the rectifier cabinet power electronic equipment composed of 6 high-power thyristor components, a thyristor device at the cold end of the forced air cooling mode is produced Microgroove group composite phase change integrated cooling system. In Embodiment 1, the wall condenser 4 whose cold end is water-cooled mode is replaced with the wall condenser 4 whose cold end is air-cooled mode, as shown in FIG. 2b. The outer wall of the wall condenser 4 in air-cooled mode at the cold end is provided with vertical rectangular rib groups 22, the height of the rectangular fins is 10mm, the thickness of the fins is 2mm, and the spacing between the fins is 4mm; the cold end is in the air-cooled mode The wall condenser 4 is installed in the air duct away from the working space of the thyristor 1. Two fans 18 with a power of 50W ar...
