[0002] As a support for electronic components, the circuit board acts as an electrical connection carrier for electronic components. During the application of the circuit board, it will generate a certain amount of heat. Not only that, the electrical components connected to the circuit board will also generate a lot of heat. If it cannot be removed in time, it will have a serious impact on the service life of the circuit board. Therefore, the circuit board needs to use heat dissipation equipment to dissipate the heat when it is in use.

[0003] The currently published patent: CN212727546U discloses a heat dissipation circuit board. Through the setting of condenser, heat dissipation fins and heat dissipation fan, the setting of heat dissipation fins and heat dissipation fan can realize the initial heat dissipation of the circuit board; through the setting of condenser and temperature sensor, when the temperature of the heat dissipation fins sensed by the temperature sensor exceeds a certain temperature value, the temperature sensor controls the condensation pump to operate, so that the condensate of the condenser circulates, takes away the heat on the heat dissipation fins, realizes the secondary heat dissipation of the circuit board, and improves the service life of the circuit board.

[0004] Based on the above search, it is found that the above patent has the following problems when used: when the heat dissipation circuit board is in use, the initial heat dissipation of the circuit board can be achieved through the setting of heat dissipation fins and heat dissipation fans. However, the heat dissipation fan is installed in the middle position of the heat dissipation fins. Therefore, the heat dissipation fan can only blow wind to the surface of the heat dissipation fins on the lower side. Therefore, only the heat dissipation fins on the lower side can be cooled, and the two ends of the heat dissipation fins cannot be cooled by blowing air, which affects the heat dissipation effect of the heat dissipation fins.

Therefore, only the heat dissipation fins on the lower side can be cooled, and the two ends of the heat dissipation fins cannot be cooled by blowing air, thereby affecting the heat dissipation effect of the heat dissipation fins.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a detachable circuit board heat dissipation device, comprising a circuit board and a heat dissipation mechanism; an electronic device is fixedly installed on the surface of the circuit board, and a heat-conducting copper plate is provided on the surface of the electronic device; the heat dissipation mechanism comprises two support rods, two connecting bridge plates, a heat dissipation fan and two guide inclined plates, the two support rods are fixedly connected to the surface of the heat-conducting copper plate, the two connecting bridge plates are respectively fixedly connected to the upper ends of the two support rods, the heat dissipation fan is fixedly connected to the opposite ends of the two connecting bridge plates, the two guide inclined plates are symmetrically fixedly installed inside the heat dissipation fan, and ventilation channels are opened at the bottom of the two connecting bridge plates, and the two ventilation channels are both trapezoidal.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The detachable circuit board heat dissipation device guides the wind through two guide inclined plates, and guides the wind to the inside of the two connecting bridge plates, and blows the wind to the surface of the heat dissipation fins at both ends through the ventilation flow channel at the bottom of the connecting bridge plates. The two ventilation flow channels are both trapezoidal, which can blow the wind in a diffused state to the outside and evenly blow it on the surface of the heat dissipation fins at the left and right ends, thereby achieving the purpose of uniform heat dissipation of multiple heat dissipation fins, thereby improving the overall heat dissipation effect of the heat dissipation fins.
