Abstract

The invention discloses a cooling plate used for an active phased-array antenna and integrated with multistage flow channels. The cooling plate comprises a cooling plate body and at least two layers of flow channels arranged on the surface of the cooling plate body, at least one layer is a main flow channel, the other layers are secondary flow channels, the flow channels are communicated with one another, and a cooling medium enters from the main flow channel. More than one water joint mounting hole is formed in the secondary flow channel; and the water joint mounting hole is used for mounting an array plane module water joint and cooling the array plane module. According to the cooling plate used for the active phased-array antenna and integrated with the multistage flow channels, the multi-stage cooling distribution flow channels are integrated in the grid framework through layering of the internal flow channels, distribution management of cooling media in an antenna array plane is achieved, the cooling effect of the antenna array plane is improved, and the installation relation of the array plane cooling devices is simplified through the layered design.

Description

technical field [0001] The invention relates to the field of active phased array antennas, in particular to a cooling plate for integrated multi-stage flow channels of active phased array antennas. Background technique [0002] There are a large number of high-density transceiver components installed in the active phased array radar antenna. The microwave circuit integrated in the transceiver component will generate a lot of heat during the working process, which will increase the temperature of the component module and reduce its performance. Excessive temperature will affect the performance and life of the active phased array antenna itself, so designing effective heat dissipation measures is becoming increasingly important in the development of active phased array antennas. At present, for the cooling pipeline design of the highly integrated antenna array, the traditional "stainless steel tube + hose" design scheme is mainly adopted. This design scheme can make the flow r...
