Description

Technical Field

[0001] The utility model relates to the technical field of rectifier module heat dissipation, in particular to a heat dissipation bottom plate with a protective structure. Background Art

[0002] The rectifier module is usually composed of multiple diodes and capacitors, which can effectively rectify the negative half cycle or positive half cycle of the AC signal. A large amount of heat energy will be generated during the operation of the rectifier module. As the temperature rises, it will affect the working performance. Therefore, a heat dissipation base plate is required to quickly dissipate the heat.

[0003] After searching, the announcement number is CN211152579U, and the name is a utility model for installing a simple and efficient heat dissipation rectifier module, including a rectifier and the substrate below. Through research and analysis, it is found that although it can reduce costs and improve heat dissipation performance without changing the performance of the base plate, the following defects still exist to a certain extent.

[0004] For example, the heat dissipation base plate has poor protective effect. The heat dissipation base plate is a bare plate structure. If it falls or is hit during storage or taking, it is easy to be scratched or deformed, resulting in loose contact, which will affect the normal use of the heat dissipation base plate and reduce the heat dissipation performance. In addition, the water-cooling shell cannot be disassembled and assembled, so it is impossible to choose the air-cooling or water-cooling cooling method according to actual usage, and the practicality is not good. In order to solve the above technical problems, we have designed a heat dissipation base plate with a protective structure. Utility Model Content

[0005] The purpose of the utility model is to provide a heat dissipation base plate with a protective structure, which has better protective effect, avoids scratches and deformation of the heat dissipation base plate, can choose water cooling and air cooling methods, and improves practicality. It solves the problems of poor protective effect of the heat dissipation base plate, affecting the heat dissipation performance, and being unable to choose water cooling or air cooling methods, resulting in poor practicality.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a heat dissipation base plate with a protective structure, comprising a base plate body, a protective film is applied to the top of the base plate body, a heat dissipation fin is fixedly connected to the bottom of the base plate body, a sealing slot is opened at the bottom of the base plate body, a water transfer shell is inserted into the inner cavity of the sealing slot, and rubber plates are glued to the four corners of the bottom of the base plate body.

[0007] Preferably, the water delivery shell comprises a shell, a plug board is fixedly connected to the top of the shell, water delivery pipes are fixedly connected to the left and right sides of the shell, and positioning blocks are welded to the tops of the front and rear and left and right sides of the shell.

[0008] Preferably, a positioning bolt is movably connected through the bottom of the positioning block, and the number of the positioning block and the number of the positioning bolts are both ten.

[0009] Preferably, a through hole is provided on the surface of the positioning block, and the bottom of the plug board is fixedly connected to the shell by welding.

[0010] Preferably, a sealing gasket is placed in the inner cavity of the sealing slot, and positioning holes are provided at the four corners of the top of the bottom plate body.

[0011] Preferably, a thread groove is formed at the bottom of the base plate body, and the number of the thread grooves is ten.

[0012] Preferably, buffer pads are glued to the four corners of the top of the protective film, and the number of the heat dissipation fins is several.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The protective film can protect the outer surface of the base plate to avoid scratches after hitting foreign objects. When it falls, the cushion pads or rubber plates at the four corners will first contact the ground, so that the impact force will not act directly on the base plate body, and the base plate body will be buffered and protected to avoid deformation of the base plate body due to impact, making the fit tighter and ensuring heat dissipation performance.

[0015] 2. When the power is large, the water delivery shell is fixed to the bottom of the base plate body by the positioning bolts, and the coolant flows into the shell to perform water cooling on the base plate body. When the power is small, there is no need to install the water delivery shell. The contact area between the base plate body and the air is increased by the heat dissipation fins to perform air cooling. In this way, personnel can choose the appropriate heat dissipation method according to actual usage to improve practicality. BRIEF DESCRIPTION OF THE DRAWINGS
