Example Embodiment

[0025] The present invention will be described in detail below with reference to the accompanying drawings and specific examples. The present embodiment is implemented in terms of the technical solution of the present invention, and a detailed embodiment and a specific operation process are given, but the scope of the invention is not limited to the following examples.

[0026] like Figure 1 ~ 3 , The present embodiment provides a self-loop power submerged jet module comprising a circuit board 1 in the housing 1 and the housing 2. Rectangular aluminum shell housing 1, provided with coolant inlet port 11 and coolant outlet port 12 in the housing 1, are using the conventional quick connector. Ends embodiment coolant inlet port 11 and coolant outlet port 12 are disposed on the same side of the housing 1 of the present embodiment. Dielectric cooling liquid cryogenic refrigerant enters from below the inlet opening 11 of the housing 1 and the internal heat exchanger circuit board 2, the...

Abstract

The invention relates to a self-circulation immersion jet power supply module which comprises a shell and a circuit board located in the shell. A refrigerant liquid inlet and a refrigerant liquid outlet are formed in the shell, an immersed pump and a jet pipe are arranged in the shell, one end of the jet pipe is connected with the immersed pump, jet holes are distributed in the jet pipe, and the shell is filled with an insulating cooling liquid. The interior of the shell is filled with the insulating cooling liquid. Compared with the prior art, by using the module of the invention,the circuit board is completely soaked in the insulating cooling liquid, a thermal resistance between a power device on the circuit board and a refrigerant can be reduced, and therefore the heat dissipation efficiency is improved, the power supply module can have the smaller size and the higher power density, and a wind noise is avoided. Meanwhile, the immersed pump and the jet pipe can accelerate flowing and circulation of the insulating cooling liquid, and the heat dissipation effect is improved.

Description

technical field [0001] The invention relates to the field of heat dissipation of power modules, in particular to a self-circulating submerged jet power module. Background technique [0002] With the development of new infrastructure construction, new energy vehicle charging piles and data center construction equipment have attracted attention, both of which are infrastructure construction based on electricity, so the power demand for power modules for power conversion is increasing. Power density requirements are getting higher and higher. As the power density of the power supply module increases, the power density of heat generated along with it also increases. The existing power modules have the following problems: First, their heating power density has reached the heat dissipation limit of traditional air cooling, and air cooling alone cannot solve the higher heat. It takes up half of the space of the entire power module, which violates the technical trend of "light, th...
