[0002] High-efficiency heat dissipation power cabinets used in power engineering are usually used to ensure that electrical equipment maintains a good operating temperature during operation to avoid overheating and cause equipment failure or performance degradation.

[0003] The existing power cabinet uses rubber pads to separate the inner cabinet from the lower cabinet and the upper cabinet, which has a good shock absorption effect. By arranging a water bag in the heat dissipation cavity, the heat in the inner cabinet can be quickly transferred to the outside of the lower cabinet, thereby realizing heat conduction and improving the heat dissipation effect. The water bag also has a certain buffering and shock absorption effect, which improves the seismic effect of the power cabinet. However, there is a problem of insufficient heat dissipation. The lower cabinet and the upper cabinet of the device form a sealed structure, in which heat is transferred in the air inside the upper cabinet and the lower cabinet, and the hot air is concentrated on the top of the inner wall of the upper cabinet, and the heat is mainly concentrated on the top of the upper cabinet, resulting in the low heat dissipation efficiency of the water bag. Therefore, technical personnel in this field provide a high-efficiency heat dissipation power cabinet for power engineering to solve the problems raised in the above background technology.
