[0002] With the development of power electronics technology, the heat generated by the power electronic power modules used by various mine underground frequency converters and rectifiers is increasing, which requires water cooling for heat dissipation. According to the explosion-proof requirements, some metal materials with good thermal conductivity containing aluminum, magnesium and other elements are not allowed to be exposed to the air in the explosion-proof cavity. The conventional explosion-proof water cooling heat sink can only use iron plate and copper plate. The water cooling heat sink made of iron material has low thermal conductivity, which affects the heat dissipation efficiency. Due to the significant increase in copper prices in recent years, the production cost of copper water cooling heat sink is very high. Therefore, under the premise of not affecting the heat dissipation effect, it is necessary to reduce the use of copper as much as possible. SUMMARY

[0008] The flange plate is arranged in the explosion-proof cavity.

[0009] The flange plate is provided with a threaded blind hole for connecting the substrate.

[0012] The inlet and outlet are made of metal pipes that meet explosion-proof requirements.

[0013] The flange plate is made of metal sheet that meets explosion-proof requirements.

[0014] The substrate is provided with countersunk holes.

[0015] The substrate is a metal sheet that does not meet explosion-proof requirements.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] The internally mounted explosion-proof water-cooled heat dissipation device features a rational structure and utilizes water cooling to improve heat dissipation efficiency. It employs bolted connections, meeting explosion-proof requirements while facilitating maintenance and installation of high-power components.
