Abstract

The invention discloses a power supply module provided with a cooling device. The power supply module comprises a casing and a power supply module disposed in the casing. The casing is detachably connected with the power supply module. The power supply module comprises a housing, a housing cover, a blower fan, and a speed regulation device used to control the blower fan. The housing comprises a front plate, a left plate, a right plate, a bottom plate, and a rear plate. The housing cover comprises a top plate and a side plate, which are in an integrated arrangement. The housing is detachably and fixedly connected with the housing cover. The front plate is provided with a ventilation opening, and the blower fan is disposed in the power supply module. The air outlet of the blower fan faces the front plate, and gaps are formed between the blower fan and the left plate and between the blower fan and the right plate. The blower fan is the speed regulation blower fan, and the speed regulation device comprises an induction module and a control chip. The induction module is disposed in the power supply module, is used to detect temperature in the power supply module, and is used to output an induction voltage. The control chip is connected with the induction module in a coupled manner, and is used to control the working power of the blower fan according to the induction voltage, and therefore cooling effect and power saving effect are realized.

Description

technical field [0001] The invention relates to a power module, in particular to a power module with a cooling device. Background technique [0002] A power supply module is a power supply that can provide power for application-specific integrated circuits, digital signal processors, microprocessors, memories, field-programmable gate arrays, and other digital or analog loads. In order to make the use of the power module more convenient and safe, the power module can be installed in the casing for use. [0003] The embedded power module assembly shown in the publication number CN105491825A includes a left and right through casing, a first power module embedded on the casing and a second power supply connected to the casing on the left side of the first power module module. Its housing includes a top plate, a bottom plate, a front plate and a rear plate. The housing is provided with a limit post to limit the position of the power module. The right side of the housing is prov...
