[0024] Such as image 3 , Figure 4 As shown, the high-power load MOS tube cooling device in this embodiment includes a radiator 1, a fan 11 is installed at the inlet end of the radiator 1, and a circuit board 4 is respectively fixed on the substrate 2 on both sides of the radiator 1. A plurality of MOS tubes 5 are installed on the circuit board 4, the body 5.1 of the MOS tube 5 is close to the surface of the substrate 2, and a fireproof insulation board 7 is arranged between the circuit board 4 and the surface of the substrate 2 of the radiator 1, and the radiator 1 An anti-vibration pad 12 is arranged between the fan 11.
[0025] In this embodiment, circuit boards 4 are arranged on both sides of the radiator 1, and MOS tubes 5 are installed on each circuit board 4, so that more MOS tubes can be installed without increasing the size of the radiator, and the utilization rate of the radiator is improved. high.
[0026] The fireproof insulating board 7 of the present embodime...
