Radar electronic equipment box

Abstract

The invention discloses a radar electronic equipment box. The radar electronic equipment box comprises a cover plate, a box frame and a bottom plate, wherein the box frame is internally provided with a main board and a plurality of groups of signal boards, which are arranged in parallel; a connector assembly is arranged at the periphery of the box frame, a radiator close to an electric reactor is fully welded on a back partition plate of the box frame, one side plate of the box frame is provided with a blowing fan assembly, the other opposite side plate of the box frame is provided with an exhaust fan assembly to accelerate heat flow circulation; a heat source module of the main board is in contact with the radiator through ceramic heat conduction plates, and the heat source module and the ceramic heat conduction insulation plates are firmly and fixedly attached on the base surface of the radiator; any one signal board can be arranged on the main board in a shaking manner relative to the main board, the any one signal board is basically vertical relative to the main board in the largest rocking angle. The radar electronic equipment box has good waterproofness, convenience in maintenance, and excellent heat radiation performance.

Description

technical field [0001] The invention belongs to the technical field of radar electronics, and in particular relates to a radar electronic equipment box. Background technique [0002] Various box products are widely used in the field of radar electronics. Among them, large electronic boxes have large volume, heavy weight, high heat generation, and more testing and maintenance. At present, radar electronic box products have the following disadvantages in application: [0003] 1) The connector is fixed on the box frame, and the front cover needs to be removed during maintenance, which increases the complexity of maintenance wiring; [0004] 2) Larger electronic products generate a relatively large amount of heat. At present, the plane of the heat source is mainly bonded to the base surface of the radiator. The base surface of the radiator is pasted with a thermally conductive silicone grease sheet, and then an air-cooled fan assembly is installed; the thermally conductive silic...

AI Technical Summary

Problems solved by technology

[0003] 1) The connector is fixed on the box frame, and the front cover needs to be removed during maintenance, which increases the complexity of maintenance wiring;

[0004] 2) Larger electronic products generate a relatively large amount of heat. At present, the plane of the heat source is mainly bonded to the base surface of the radiator. The base surface of the radiator is pasted with a thermally conductive silicone grease sheet, and then an air-cooled fan assembly is installed; the thermally conductive silicone grease sheet Contains three layers of insulating layer, heat transfer layer, and insulating layer. Generally, heat can be transferred quickly, but when there is a lot of heat, there is thermal resistance between different layers of the silicone grease sheet, which is not enough to conduct heat quickly; in addition, only through the blowing fan to dissipate heat , the heat dissipation speed needs to be improved;

[0005] 3) Most of the internal circuit boards are placed flat and fixed in the box with screws. When the circuit boards are placed in multiple layers, the disassembly and wiring in the later maintenance process are very cumbersome;

[0006] 4) The contact between the radiator and the box is usually fixed by screws, and there are inevitably gaps, which may cause water infiltration
