[0014] 1. In the utility model, a camera module photosensitive component is designed, and the heat dissipation mechanism in the device is used to dissipate the heat of the photosensitive component body. The photosensitive component body is installed on a circuit board, and a micro fan is started. The micro fan sends air into an accelerating tube. After the airflow is accelerated in the accelerating tube, it flows into the heat dissipation tube along the inclined guide groove. The air entering along the inclined guide groove will form a vortex in the heat dissipation tube. The vortex will flow along the heat dissipation tube. When flowing, the outer vortex will rub against the wall of the heat dissipation tube, and the angular velocity of the outer vortex will slow down, while the angular velocity of the central vortex remains unchanged. The inner and outer vortices with different angular velocities will generate friction, and the central vortex will consume internal energy through friction. The temperature of the outer vortex increases due to friction, and the temperature of the outer vortex rises. The high-temperature outer vortex and the low-temperature central vortex flow toward the sealing plug together, and the high-temperature outer vortex flows out through the gap between the sealing plug and the heat pipe, while the low-temperature central vortex is blocked by the sealing plug. The low-temperature central vortex accumulates near the sealing plug. The pressure near the sealing plug is higher, causing the low-temperature central vortex to flow in the opposite direction. The low-temperature vortex flowing into the heat transfer plate absorbs the heat generated by the operation of the photosensitive component body through the heat pipe and the heat transfer plate, thereby improving the heat dissipation effect of the photosensitive component body and solving the problems of poor heat dissipation effect and inconvenience in use of the existing photosensitive component.
