Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of power supply equipment, in particular to a charger with a heat dissipation plate. Background Art
[0002] With the development of science and technology, users have higher and higher demands for the power and intelligence of chargers. In order to realize high-power and intelligent chargers, a large number of electronic components are usually set on the PCM board of the charger. As more and more electronic components are arranged on the PCM board, heat dissipation becomes a major problem affecting the functionality of the equipment. In order to dissipate heat and cool the PCM, the conventional practice in the industry is to add thermal conductive silicone to the electronic components, and then conduct the heat to the outside through the aluminum shell to achieve the function of dissipating heat for the electronic components. The disadvantage of this approach is that the heat generated when the entire PCM is working will first pass through the electronic components set on it, and then dissipate heat to the outside through the heat sink, which has a great impact on the life of the electronic components and the stability of the overall product. Utility Model Content
[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a charger with a heat dissipation plate which can dissipate heat by itself and avoid heat passing through electronic components, thereby improving product stability and service life.
[0004] The technical solution adopted by the utility model is: the utility model includes a shell and a PCM main control board arranged in the shell, a plurality of heat dissipation through holes and a thermal conductive silicone pad are arranged on the PCM main control board, the plurality of heat dissipation through holes are distributed on the PCM main control board around the center of the PCM main control board, the shape of the thermal conductive silicone pad is consistent with the distribution shape of the plurality of heat dissipation through holes, and is pressed between the PCM main control board and the inner wall of the shell.
[0005] Furthermore, a plurality of the heat dissipation through holes are coaxially arranged in a rectangular shape on the PCM main control board, and the thermal conductive silicone pad is a square circle and covers the positions where the plurality of the heat dissipation through holes are distributed.
[0006] Furthermore, a heat sink and a heat conductor are provided in the shell. The heat sink is an "X"-shaped aluminum bracket, and the heat conductor is made of silicone and is compressed between the heat sink and the PCM main control board.
[0007] Furthermore, a heat dissipation fan is arranged in the shell at a position close to the heat dissipation element, and a heat dissipation vent is opened on a plate of the shell on a side corresponding to the heat dissipation fan.
[0008] Finally, the housing is made of aluminum.
[0009] Compared with the prior art, the beneficial effects of the utility model are as follows: a circle of heat dissipation through holes is arranged around the center point of the device itself on the PCM main control board to dissipate heat for the PCM main control board itself, and at the same time, the heat is transferred to the shell through the heat conductive silicone pad between the PCM main control board and the inner wall of the shell under pressure. Since the shell is made of aluminum material, it has good thermal conductivity, and finally the heat emitted by the electronic components on the PCM main control board is transferred to the outside through the shell, realizing the function of dissipating heat and cooling the inside of the device. Therefore, the utility model dissipates heat by itself, avoids heat passing through the electronic components, and thus improves the stability and service life of the product.

In this embodiment, the plurality of heat dissipation holes 3 are coaxially arranged on the PCM main control board 2 in a rectangular shape, and the thermal conductive silicone pad 4 is a square circle and covers the positions where the plurality of heat dissipation holes 3 are distributed. The housing 1 is made of aluminum. The utility model provides a circle of heat dissipation through holes 3 arranged around the center point of the device itself on the PCM main control board 2 to dissipate heat for the PCM main control board 2 itself, and at the same time, the heat is transferred to the shell 1 through the heat conductive silicone pad 4 between the PCM main control board 2 and the inner wall of the shell 1 under pressure. Since the shell 1 is made of aluminum material, it has good thermal conductivity. Finally, the heat emitted by the electronic components on the PCM main control board 2 is transferred to the outside through the shell 1, thereby realizing the function of dissipating heat and cooling the inside of the device.

A heat dissipation fan 7 is further provided in the housing 1 near one side of the heat sink 5. A heat dissipation vent 8 is provided on a side panel of the housing 1 corresponding to the heat dissipation fan 7. The heat sink 5 is composed of a heat receiving block, two heat dissipation blocks and two connecting blocks. The two heat dissipation blocks are perpendicular to the heat receiving block and fixedly connected to the left and right ends of the heat receiving block. The two connecting blocks are respectively arranged at the bottom of the two heat dissipation blocks. The connecting block and the heat dissipation block are perpendicular to each other to form a "J"-shaped heat sink 5. The heat sink 5 is fixedly arranged on the inner wall of the other side of the housing 1 corresponding to the PCM main control board 2 through the two connecting blocks. The heat conductive member 6 is attached to the heat receiving block and pressed against the PCM main control board 2 to assist in heat dissipation. At the same time, the heat dissipation fan 7 can be turned on according to the actual heating situation to blow the heat in the housing 1 to the outside through the heat dissipation seal 8.
