[0003] Therefore, a high-power wireless charging module is needed to solve the problems raised in the above background technology. Utility Model Content

[0004] The purpose of the present invention is to provide a high-power wireless charging module to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] The heat dissipation mechanism includes a cooling back plate fixedly connected to the bottom of the wireless charging module body, a guide pipe is fixedly connected to the inside of the cooling back plate, a connecting sleeve is fixedly connected to the outer wall of the guide pipe at a position close to the wireless charging module body, an air intake pipe is fixedly connected to the top of the connecting sleeve, a miniature high-speed fan is fixedly connected to the inside of the air intake pipe and above the wireless charging module body, a guide groove is opened on the outer wall of the guide pipe and in the connecting sleeve, a connecting piece is fixedly connected to the outer wall of the guide pipe at one end close to the connecting sleeve, a reflux block is fixedly connected to the outer wall of the connecting piece in the guide pipe, an air outlet plate is fixedly connected to the outer wall of the cooling back plate on the side away from the air intake pipe, an air outlet groove is opened in the air outlet plate, and a dust net is fixedly connected to the top of the air intake pipe.

[0008] As a preferred solution of the utility model, the base plate is made of aluminum alloy, and the connection method between the power interface, the electronic button and the wireless charging module body is electrical connection.

[0009] As a preferred solution of the utility model, the guide pipe, connecting sleeve, connecting plate, return block and air outlet plate are all made of ABS plastic, the shape of the cooling back plate is adapted to the shape of the wireless charging module body, and the connection method between the cooling back plate and the base plate is a fixed connection.

[0010] As a preferred solution of the utility model, the air intake pipe passes through the connecting sleeve and extends to the top of the cooling back plate, the cooling back plate is made of copper, the air intake pipe, the miniature high-speed fan, the connecting sleeve, the guide groove and the connecting plate are all provided in multiple groups, and the guide groove is obliquely arranged in the guide pipe.

[0012] As a preferred solution of the utility model, the air outlet plate is designed as an L-shaped structure, and the connection method between the micro high-speed fan and the power interface is electrical connection.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. In the utility model, a high-power wireless charging module is designed, and the heat dissipation mechanism in the device is used for heat dissipation. The power connector is inserted into the power interface, and the electronic button is pressed. The electronic button starts the wireless charging module body and the micro high-speed fan, and the wireless charging module body starts to run. The micro high-speed fan will send outside air into the air intake pipe. The air entering the air intake pipe will form a high-speed airflow. The high-speed airflow flows downward along the air intake pipe into the connecting sleeve. The high-speed airflow in the connecting sleeve flows into the guide pipe along the inclined guide groove. The air entering along the inclined guide groove will form a vortex in the guide pipe. The vortex will flow to the left along the guide pipe. The closer the angular velocity of the vortex flowing in the guide pipe is to the center, the greater the rotation angular velocity. Due to the different angular velocities, friction is generated between the layers of the free vortex. The result of the friction is that the energy of the central vortex is transferred to the airflow with lower angular velocity in the outer layer. The vortex in the central layer loses energy, and the kinetic energy and internal energy are reduced. The temperature of the central layer vortex decreases, the outer layer vortex gains energy, the kinetic energy and internal energy increase, the temperature and flow rate of the outer layer vortex increase, the low-temperature central vortex will be blocked by the reflux block, and the high-temperature outer layer vortex will flow out along the gap between the guide pipe and the reflux block. The low-temperature central vortex accumulates near the reflux block, and the pressure near the reflux block is higher, causing the low-temperature central vortex to flow to the right. The low-temperature vortex flowing to the right will flow into the cooling back plate, and the low-temperature vortex absorbs the heat generated by the wireless charging module body during operation through the cooling back plate. The vortex that absorbs heat will flow out along the air outlet slot, and the outflowing vortex will increase the air flow rate on the surface of the wireless charging module body, accelerate the surface heat loss rate of the wireless charging module, and improve the heat dissipation efficiency of the wireless charging module body. This solves the problem that the existing high-power wireless charging module relies on an aluminum heat sink for natural heat dissipation, but due to its large operating power, it generates more heat during operation, and the heat dissipation effect of the aluminum heat sink is poor.
