A heat dissipation assembly structure of a switching power supply

Abstract

The invention discloses a heat dissipation assembly structure of a switching power supply, and relates to the technical field of assembly structures. The invention comprises a support frame and a mounting plate, a heat dissipation mechanism is arranged on the upper surface of the mounting plate, a fixed plate is fixedly connected to the upper surface of the support frame, a plate groove is arranged on the bottom surface of the mounting plate, a plurality of backing plates are fixedly connected to the upper surface of the support frame, and a plurality of backing plates The center line of the support frame is arranged symmetrically, the upper surface of the backing plate is fixedly connected with the inserting column, the bottom surface of the mounting plate is provided with a number of pad grooves, the inner surface of the pad groove is provided with slots, the upper surface of the mounting plate is provided with a baffle, and the surface of the baffle is provided There are air intake slots. The present invention saves the conventional screw fixing method of the mounting plate by setting the fixing plate, the plate groove, the inserting column, the slot and the air intake groove, so that the installation efficiency of the structure is higher, the structure is stable after installation, and the heat dissipation effect is better at the same time. The dust-proof effect is better, and there is no need for users to clean up the dust afterwards.

Description

technical field [0001] The invention belongs to the field of assembly structures, in particular to a cooling assembly structure for switching power supplies. Background technique [0002] At present, the existing switching power supply needs to set the MOS, rectifier bridge, Schottky diode and other heating components separately on a heat dissipation structure. The switching power supply mounting plate is locked on the bracket by screws. There is no positioning device between the mounting plate and the bracket, and it is easy to shake when fixed, which affects the installation efficiency and consumes time and energy; the heat dissipation effect is average, and the heat dissipation structure is easy to accumulate dust under long-term use, which has a certain impact on heat dissipation. After dust accumulation, it needs to be disassembled and cleaned; therefore, a heat dissipation assembly structure of switching power supply is proposed. Contents of the invention [0003] T...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a heat dissipation assembly structure for switching power supply. By setting a fixed plate, a fixed column, a plate groove and a column groove, the existing installation plate has no positioning device during installation, and the problem that shaking is easy to affect the installation is solved; Set up posts, slots, spring slots, first springs and card slots, which solves the problem that the existing mounting plate and bracket need to be fixed by screws, resulting in low installation efficiency, time-consuming and labor-intensive problems; by setting the baffle , air intake slot, deflector and adsorption layer, which solves the problem of serious dust accumulation in the heat dissipation structure under long-term use and affects the heat dissipation; by setting the cooling fan, the problem of general heat dissipation effect of the heat dissipation mechanism is solved; by setting the rotating groove and the rotating shaft , rotating blades and brush heads, which solve the problem that the heat dissipation structure needs to be disassembled and cleaned after dust accumulation
