[0021] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] An inverter is a device that converts direct current into alternating current. It usually contains multiple electronic components, some of which generate a certain amount of heat during operation. Common heat-generating components in inverters include: Power semiconductor devices: The main heat-generating components in inverters are usually power semiconductor devices, such as transistors (IGBT, Insulated Gate Bipolar Transistor) or MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor). These devices generate heat during the switching process, especially in high-power, high-frequency inverters.

[0023] Rectifier and filter: Inverter power supplies usually contain rectifiers to convert AC power into DC power. The diodes or other rectifier components in the rectifier will also generate a certain amount of heat when working. In addition, the filter is used to smooth the DC power, and the inductor components in it may also generate heat.

[0024] For the heat dissipation solution of the heat generating components in the above inverter power supply, please refer to Figure 1-4 As shown, the utility model provides a heat dissipation unit for an inverter power supply, which includes: a frame 11, a heat dissipation fan 12, a heat sink 13, a heat pipe 14, a support seat 15, and a heat dissipation patch 16.

[0025] The cooling fan 12 is fixedly arranged on the frame 11, one side of the cooling fan 12 is the air inlet end, and the other side of the cooling fan 12 is the air outlet end. The heat sink 13 is fixedly arranged on the frame 11 and is respectively arranged at the air inlet end and the air outlet end. The cooling fan 12 is an axial flow fan, and the rotation axis of the cooling fan 12 is arranged in the horizontal direction. Therefore, during the operation of the cooling fan 12, the airflow can be guided along the axial direction, and together realize effective air cooling and heat dissipation of the heat sinks 13 arranged on both sides thereof.

[0026] The support base 15 is connected to the frame 11, and the support base 15 includes a plate body 151 and a mounting foot 152. The mounting foot 152 is set at the corner end of the plate body 151, and the overall installation of the support base 15 is achieved through the mounting foot 152. A receiving groove 153 and a mounting column 154 are set at the bottom of the plate body 151. The opening of the receiving groove 153 faces the bottom. The receiving groove 153 is set to jointly realize the accommodation and placement of the heat pipe 14, thereby improving the concentrated heat conduction at the bottom.

[0027] One end of the heat pipe 14 is passed through the interior of the heat sink 13 located at the air inlet end. The heat pipe 14 and the heat sink 16 are made of copper, and the heat sink 13 is made of aluminum. The other end of the heat pipe 14 is passed through the interior of the heat sink 13 located at the air outlet end. The middle part of the heat pipe 14 is accommodated in the accommodating groove 153. The heat pipe 14 passed through the heat sink 13 is arranged in a vertical direction. Multiple heat pipes 14 are passed through the interior of the heat sink 13, so that the heat conducted by the heat sink 16 located at the bottom transfers the heat to the heat pipe 14 from bottom to top, and effective cooling is achieved through the heat sink 13. On the one hand, this arrangement position relationship can improve the installation efficiency of the heat-generating components and facilitate assembly; on the other hand, it can effectively utilize the physical characteristics of the hot air having a small density and moving in an upward direction during the conduction process to improve the heat dissipation efficiency.

[0028] The heat sink 16 is fixedly connected to the support base 15 through the mounting column 154 . The heat sink 16 is attached to the bottom of the heat pipe 14 . The heat sink 16 is used to attach to the heat-generating component and transfer the heat of the heat-generating component to the heat pipe 14 .

[0029] Heat sinks 13 are respectively arranged on both sides of the heat dissipation fan 12. The airflow is transported from the air inlet end to the air outlet end through the operation of the heat dissipation fan 12 to achieve heat dissipation of the heat sink 13 along the airflow direction. A heat pipe 14 is inserted into the heat sink 13. The middle part of the heat pipe 14 is accommodated in the accommodating groove 153 of the support seat 15. The heat of the heat-generating component is transferred to the heat dissipation patch 16 through the arrangement of the heat dissipation patch 16, and then the heat is transferred to the heat pipe 14. Under the operation of the heat dissipation fan 12, the heat is dissipated and cooled on the heat sink 13. Therefore, the heat dissipation fan 12, the heat sink 13, the heat pipe 14 and the heat dissipation patch 16 are reasonably arranged to form an overall heat dissipation solution, thereby improving the heat dissipation performance of the inverter power supply and ensuring its working stability and performance.
