This heat dissipation structure is suitable for low power situations, but in high power situations, since the heat cannot be discharged from the cabinet in time, the heat generated in the cabinet will be greater than the heat dissipation, causing the temperature in the cabinet to rise to a higher temperature to achieve thermal balance. At this time, the heat in the cabinet will cause the temperature of other electronic components to rise, thereby affecting the life and reliability of the electronic components. Utility Model Content

The front end of the heat dissipation duct 2 is connected to the rear of the mounting bracket 1, and the rear end of the heat dissipation duct 2 is connected to the rear door panel 4 and communicates with the air outlet 10 thereon. The cross-sectional area of the heat dissipation duct 2 is slightly larger than the cross-sectional area of the power module 5. The rear of the power module 5 is located in the front port of the heat dissipation duct 2. When the built-in fans of each functional module are working, cold air flows from the outside of the cabinet through the filter window on the front door panel 3 into each functional module, and then flows out from the rear of the module to the heat dissipation duct 2, which can ensure that the hot air does not escape to the maximum extent and is discharged from the air outlet 10 on the rear door panel 4 along the heat dissipation duct 2 outside the cabinet. The heat dissipation duct 2 is respectively connected to the mounting bracket 1 and the rear door panel 4 to form a closed independent duct.
[0019] A filter window 9 formed by filter material is provided on the back side of the front door panel 3 and located on the air inlet 6. The filter window 9 can filter out and absorb dust in the air.
[0020] The utility model is installed on the cabinet of a power supply complete set product, and the power module is a part of the power supply complete set product. The cabinet frame 8 used to connect the front door plate 3 and the panel 7 is a pair of vertical rods with a C-shaped cross section. One side of the two vertical rods is respectively connected to the two sides of the panel 7, one side of which is connected as a hinge, and the other side is connected to the front door plate 3 through a latch structure. The latch structure includes a latch and a socket. The latch is plugged into the socket to realize the connection between the front door plate and the cabinet frame.
[0021] The advantages of connecting the front door panel and the cabinet frame are: 1.
