The PCBA assembly 10 is used to receive the temperature sensor and control the cooling system. When a certain component reaches the specified temperature, the temperature sensor sends a command, and the PCBA assembly 10 controls the water pump to work, that is, the cooling system starts the working mode to cool the component. The PCBA assembly 10 is a prior art and will not be described in detail.

The lower shell 1 is provided with a plurality of long screw holes 7 matched with the long screws 5, and the outer surfaces of the long screws 5 are also respectively covered with gaskets 8.

[0028] like Figure 2 As shown, the long screw 5 passes through the upper ear plate 6 and the gasket 8, and is threadedly connected to the inner wall of the long screw hole 7, so as to fix the upper shell 3. The gasket 8 is provided to prevent the long screw 5 and the long screw hole 7 from loosening, and the squeezing effect of the upper shell 3 on the sealing gasket 9 can be further improved, thereby improving the sealing performance.

[0029] When the utility model is in use, the sealing gasket 9 provided between the upper shell 3 and the lower shell 1 can improve the sealing effect inside the actuator, thereby preventing the entry of impurities such as dust and water vapor, so that the PCBA assembly 10 is always in a good environment for operation; the heat sink 4 provided can accelerate the heat dissipation efficiency inside the actuator; the thermal grease 14 is an insulator, which can block electricity and conduct heat, and can improve the heat dissipation efficiency of the PCBA assembly 10 while preventing short circuit.
