[0004] Therefore, a directional heat dissipation device for the frequency converter inside the compact spinning box of a spinning machine is needed. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a directional heat dissipation device for a frequency converter inside a compact spinning box of a spinning machine, comprising a box body, a heat dissipation mechanism fixedly installed inside the box body, and an air supply mechanism fixedly installed on the inner wall of the box body; the heat dissipation mechanism includes a frequency converter, an mounting component fixedly installed on the side of the frequency converter, the mounting component having threaded holes extending vertically through it, a fastening bolt threaded onto the inner wall of the threaded holes, the fastening bolt being threadedly connected to the inner wall of the box body, a first fixing component fixedly installed on the inner wall of the box body, a pump fixedly installed on the side of the first fixing component, a connecting pipe fixedly installed on the side of the pump, a second fixing component fixedly installed on the inner wall of the box body, a water tank fixedly installed on the side of the second fixing component, a through groove fixedly opened on the top surface of the water tank, and a water inlet fixedly installed on the inner wall of the through groove.

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

[0014] 1) The inverter inside the compact spinning box of this spinning machine is connected to a heat dissipation device. When in use, first open the water inlet and add sufficient refrigerant to the water tank. Then, turn on the pump to drive the refrigerant inside the water tank to be transferred to the transmission copper pipe through the connecting pipe. At the same time, the heat generated by the inverter is dissipated through the heat dissipation fins. Then, the heat inside the heat dissipation fins is carried away by the transmission coil that runs through the heat dissipation fins. The refrigerant inside the transmission coil is continuously circulated by the pump to cool the heat dissipation fins installed on the side of the inverter. This can improve the cooling effect of the cooling device on the inverter, improve the practicality of the device, and improve the stability of the device during operation.

[0015] 2) The inverter inside the compact spinning box of the spinning machine is connected to the heat dissipation device. While the heat dissipation mechanism is in use, the air inlet component is opened to draw cool air from outside the box into the box. At the same time, the air outlet component is opened, and the air outlet component receives the cool air drawn in by the air inlet component. During this process, the cool air passes over the box and carries away the heat generated inside the box, and is carried out of the box through the air outlet component. This cycle is repeated to cool the box and works in conjunction with the heat dissipation mechanism to improve the heat dissipation effect on the inverter, thereby improving the practicality of the device.
