Detailed Description

The technical solution of the present invention will be described in further detail through the following embodiments.

As shown in fig. 1 and 2, an optimized structure based on inverter heat dissipation comprises an inverter main body and a groove-shaped bearing body arranged on the inverter main body, wherein an access inductor of the inverter main body is arranged in the groove-shaped bearing body, the groove-shaped bearing body is a cuboid framework 1, a first heat insulation layer is arranged on a framework surface connected with the inverter main body and on the cuboid framework 1, a heat conduction pad 3 and a reinforcing rib 2 are respectively arranged in the rest five framework surfaces of the cuboid framework 1, the reinforcing rib 2 is arranged outside the heat conduction pad 3, and heat conduction glue is poured and sealed at the joint of the first heat insulation layer and the heat conduction pad 3.

The heat conducting pad 3 has good heat conducting, insulating and dustproof effects, and meanwhile, the framework type bearing body reduces the influence of the bearing body on the heat radiating speed. Cuboid skeleton 1 plays the supporting role to heat conduction pad 3, still plays the effect of certain safe support to the inductance that sets up in the supporting body simultaneously, prevents that the mistake from bumping and damaging the inductance. The reinforcing ribs 2 reinforce the strength of the cuboid framework 1. The first heat insulation layer isolates heat generated by the inductor, and influences on the inverter main body are reduced. In practice, the first heat insulation layer is provided with a through hole, and a connecting wire of the inductor penetrates through the through hole to be connected with the inverter main body. In this embodiment, the reinforcing ribs 2 in each frame surface and the frame body form a plurality of triangles, and the triangles formed by the reinforcing ribs 2 and the frame body further enhance the strength of the rectangular parallelepiped frame 1. In this embodiment, the thickness of the thermal pad 3 is 0.5mm to 1 mm.

Preferably, the groove type supporting body is externally covered with a shielding case 4, one side of the shielding case 4 is provided with an air inlet 5, the air inlet 5 is provided with a fan 6, one side of the shielding case 4 opposite to the air inlet 5 is provided with an air outlet, the air outlet is provided with an air pipe 7, and the tail end of the air pipe 7 is communicated with the outside of the cabinet body of the emergency power supply equipment cabinet. During the use, the inductance heat production in the carrier, the heat conducts the air in the cage 4 through heat conduction pad 3, and fan 6 work is discharged the outside to the emergency power supply cabinet through tuber pipe 7 with hot-air, and the radiating rate is fast, and avoids long-pending heat and influence other equipment in the emergency power supply cabinet. Besides the function of thermal isolation, the isolation cover 4 also has the function of supporting and protecting the inductor in the bearing body, and makes up for the defect that the rectangular framework has weak protection effect on the inductor. In other embodiments, the fan 6 may be replaced by a blower disposed on the air duct 7, and the isolation hood 4 is communicated with the outside of the emergency power supply cabinet through the blower and the air duct 7.
