Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning drivers, in particular to an air-conditioning driver with strong heat dissipation. Background Art

[0002] The air conditioner driver is a component in the air conditioner used to control the operation of the air conditioning system. By monitoring and controlling the operating status and parameters of the air conditioning system, it can achieve precise control of indoor temperature and humidity. Various electronic components are installed on the air conditioner driver motherboard. The electronic components will generate a lot of heat during operation, so the air conditioner driver needs to be cooled.

[0003] A patent with publication number CN 217235884 U discloses a heat dissipation structure for an air conditioner driver, comprising: a controller body, the controller body comprising an outer shell and a control unit arranged in the inner cavity of the outer shell; the heat dissipation assembly comprising heat dissipation fins mounted on the controller body and in contact with the control unit, a mounting plate arranged on the top of the heat dissipation fins, and bolts passing through the mounting plate and screwed to the outer shell; the combination of the heat dissipation assembly and the outer shell facilitates rapid disassembly, maintenance, and installation of the heat dissipation assembly; the heat dissipation assembly also comprises a cavity arranged in the middle of the heat dissipation fins and a fan arranged inside the cavity, wherein the cavity is connected to the bottom of the heat dissipation fins on the rear side of the heat dissipation fins to form an L-shaped cavity. When in use, the fan is powered, and the air is absorbed from the rear side of the heat dissipation fins and discharged from the bottom below the heat dissipation fins through the air outlet of the fan.

[0004] However, since the heat accumulation in the air conditioner driver increases when the operating power is high, and the heat accumulation in the driver decreases when the operating power is low, the existing air conditioner driver heat dissipation structure cannot adjust the heat dissipation speed according to the temperature inside the driver during use. The temperature inside the driver cannot be dissipated in time, which will still cause electronic components to burn out, resulting in poor heat dissipation effect. Therefore, to address the above problems, an air conditioner driver with strong heat dissipation is proposed. Utility Model Content

The two inner walls of the drive housing 1 with the No. 1 air vent 8 are horizontally fixed with limiting ribs 11, and the U-shaped plate 9 is slidably set on the limiting ribs 11 through the sliding rib grooves 12 opened on its outer side surface. The closing strip 10 is vertically fixed between the parallel side walls of the U-shaped plates 9 in the two groups of pushing assemblies.

[0036] When working, when the operating power of the air-conditioning driver is large, the heat accumulation inside it will increase, and when the operating power of the driver is small, the heat accumulation inside it will decrease. The existing air-conditioning driver heat dissipation structure cannot adjust the heat dissipation speed according to the temperature inside the driver when in use. The temperature inside the driver cannot be dissipated in time and will still cause the electronic components to burn, resulting in poor heat dissipation effect. In this solution, the circuit board 4 is fixedly installed on the mounting plate 2 in the driver housing 1, and the circuit board 4 is attached to the side of the bonding plate 6. During normal use, the heat generated by the electronic components on the circuit board 4 during operation will be transferred to the bonding plate 6 and dissipated outward through the No. 1 heat dissipation fin 7 installed on the side of the bonding plate 6, and the temperature sensing module on the circuit board 4 will sense the driver housing 1 The temperature inside is monitored in real time. When the temperature inside the driver housing 1 rises, the temperature sensing module sends a signal to the control module. The control module controls the two electric telescopic rods 13 in the two pushing components to extend at the same time. When the two electric telescopic rods 13 extend, they drive the two U-shaped plates 9 to translate in the driver housing 1 through the limiting ribs 11 and the sliding rib grooves 12. When the two U-shaped plates 9 translate, they drive the multiple closing strips 10 installed on the inside thereof to translate, and when the closing strips 10 translate, they move in the opening of the No. 1 ventilation groove 8, and then open the opening of the No. 1 ventilation groove 8 on the inside of the driver housing 1, so that the driver housing 1 is connected to the outside world through the No. 1 ventilation groove 8, and cooperates to control the operation of the fan 17. When the fan 17 is running, it will pass The No. 1 ventilation slot 8 blows air into the driver housing 1. After the airflow enters the driver housing 1, it will blow onto the No. 1 heat dissipation fin 7 and the bonding plate 6, and then the heat on the bonding plate 6 and the No. 1 heat dissipation fin 7 will be taken away by the airflow, so as to cool the bonding plate 6 and the No. 1 heat dissipation fin 7. The bonding plate 6 and the No. 1 heat dissipation fin 7 will then cool the circuit board 4. After the airflow passes through the bonding plate 6 and the No. 1 heat dissipation fin 7, it will blow from the gap between the side of the circuit board 4 and the driver housing 1 to the side of the protective shell 19, and the airflow will be discharged from the No. 1 ventilation slot 8 on the other side of the driver housing 1 into the protective shell 19, and then discharged from the inclined slot 20 and the opening at the bottom of the protective shell 19, and the No. 2 heat dissipation fin 22 set through the upper and lower parts of the driver housing 1 will also cool the driver The heat in the housing 1 is dissipated outward, thereby reducing the temperature in the driver housing 1, so as to cool the electronic components on the circuit board 4. The temperature in the driver housing 1 is monitored by the temperature sensing module, and the extension length of the electric telescopic rod 13 is controlled by the control module according to different temperatures. The extension length of the electric telescopic rod 13 is different, and the opening size of the closing strip 10 to the first ventilation groove 8 is also different, thereby adjusting the air intake of the fan 17 into the driver housing 1 to prevent the heat accumulation in the driver housing 1 from being too low and the air flow from being too large, causing the temperature of the bonding plate 6 and the first heat dissipation fin 7 to be too low and condensation to form. In addition, the air intake can be increased when the heat accumulation in the driver housing 1 is large, so as to quickly cool the bonding plate 6 and the first heat dissipation fin 7.The bonding plate 6 and the first heat sink fin 7 cool down the electronic components on the circuit board 4, and cooperate to adjust the heat dissipation speed. The air intake volume can be adjusted according to the actual temperature. Compared with the traditional air conditioner driver heat dissipation structure, the heat dissipation effect is better.
