(III) advantageous effects

The invention has the following beneficial effects:

1) the radiator and the four side plates of the traditional case are printed into an integral whole through 3D, the functional modules are fixed through bottom screws, assembly steps and time are reduced, the upper-layer partition plate is designed to split the product functional modules into the power module and the acquisition module, and maintainability of the integrated case is improved.

2) The chassis is an integral frame structure, and stress generated by the upper part can be shared to the lower chassis more uniformly. Meanwhile, the design of the cavity at the corner of the box body can reduce the weight of the product on the basis of enhancing the mechanical performance of the structure. The tubular structure of the bottom of the chassis designed for mounting the power module will also enhance the rigidity of the air duct area.

3) The heat of the product is mainly conducted to the heat dissipation fins by the mounting surface of the module in the box body, and the heat dissipation is carried out through forced air cooling. After the box body is integrally formed, the heat conduction between the fins and the heat conduction between the mounting surface and the side plate of the case are enhanced, and the effective heat dissipation area is increased.

4) After the structure of the main stress area is strengthened, the basic wall thickness of the case can be controlled within 1.2mm due to the good bearing capacity of the integrated case body, meanwhile, the structural weight increased by a plurality of process fillets can be eliminated, and the weight of the case body is obviously reduced.
