Description

Liquid cooling machine case

Technical Field

The application relates to the technical field of additive manufacturing, in particular to a liquid cooling machine box based on an additive manufacturing technology.

Background

The airborne radar is mainly responsible for the functions of excitation signal generation, amplification, echo signal amplification, acquisition, processing, recording and the like. The airborne radar chassis is an important part of an airborne radar, and integrates various important functions such as radar radio frequency, signal processing, power supply and the like.

Most of the existing airborne radar cases adopt an air cooling or liquid cooling mode to perform temperature control heat dissipation on the internal environment of the airborne radar cases. The liquid cooling machine box has strong cooling capacity, so the liquid cooling machine box is widely applied to high-power airborne radar machine boxes. Compared with a common liquid cooling machine box, the airborne radar liquid cooling machine box has higher requirements on environmental adaptability, volume and weight. The existing airborne radar liquid cooling chassis can be generally completed through multiple complex processes such as cold plate welding, cold plate processing, chassis welding, chassis processing, chassis assembly, electric installation and the like.

However, the applicant finds that the welding mode can increase the overall weight of the liquid cooling machine box, and the welding position can be a relatively weak place of the whole liquid cooling machine box, so that the leakage of cooling liquid can be caused by the failure of a welding line at the liquid cooling flow passage in the liquid cooling machine box, and the reliability and the safety of the whole airborne radar can be directly influenced.

Based on this, the applicant believes that the lightweight and reliability of the liquid cooling chassis at present still need to be improved.

Compared with a common liquid cooling machine box, the air-borne radar liquid cooling machine box has higher requirements on the tightness and reliability of an internal cold channel and a cold channel butt joint position, and not only can bear severe mechanical environment influence, but also can ensure the dimensional accuracy of each plug-in guide rail groove after the air-borne radar liquid cooling machine box is molded.

FIG. 1 is a schematic diagram of a conventional liquid-cooled chassis; fig. 2 is a schematic diagram of another structure of an existing liquid-cooled chassis. As shown in fig. 1 or fig. 2, the welding forming mode of the existing liquid cooling chassis needs to perform separate welding processing on each plate, and reserve a welding interface and a screw interface, so that after the liquid cooling chassis is welded and formed, finish processing after welding is performed again through the welding interface and the screw interface.

However, the applicant finds that the welding forming mode not only can increase the overall weight of the liquid cooling cabinet, but also has higher requirements on the structural form, precision distribution, material selection, process reliability and the like of each plate (such as a cold plate). The continuous realization of the cold channels on the cold plate is complex, and the quality and welding deformation of the welding seams among the plates are not easy to control, so that the reliability of the liquid cooling cabinet is lower.

Based on the structure, the application provides the liquid cooling machine box, which is characterized in that the cabinet body, the liquid cooling component and the liquid cooling runner of the liquid cooling machine box are integrally formed by using the additive manufacturing technology, so that the reliability problem caused by a welding mode is avoided, and the safety of the liquid cooling machine box is improved; and the liquid cooling assembly and the liquid cooling runner are integrally formed, so that the weight reduction of the liquid cooling cabinet can be improved.
