The invention discloses a phased array antenna microchannel four-layer two-phase cold plate, which comprises a cover plate, an upper cold plate, a middle cold plate and a lower cold plate arranged sequentially from top to bottom, the upper cold plate, the middle cold plate and the The lower cold plates are connected with each other, and the cover plate is connected with the upper cold plate; the upper cold plate is provided with a coolant outlet, the middle cold plate is provided with a middle through hole, and the lower cold plate is provided with a coolant inlet, and the coolant flows from the lower cold plate The cooling liquid inlet enters, passes through the middle layer through hole on the middle layer cold plate, and flows out from the cooling liquid outlet of the upper layer cold plate. A phased array antenna micro-channel four-layer two-phase cold plate provided by the present invention adopts the combination of micro-channel cooling and phase-change cooling technology, combined with an optimized channel structure, and can control the maximum temperature of the array at the working temperature In addition, it can improve the temperature uniformity of the phased array antenna, and can be applied in many different occasions.
Description
technical field [0001] The invention belongs to the field of aerospace technology, and in particular relates to a phased array antenna microchannel four-layer two-phase cold plate. Background technique [0002] The phased array antenna is highly integrated, contains a huge number of T / R components, and has a heat flux of hundreds of watts. At present, the thermal control technology of phased array antennas mainly focuses on micro-channel liquid cooling technology, which uses single-phase forced convection heat transfer, but it is difficult to ensure the uniform temperature of the antenna array. The most commonly used solution so far is to optimize the flow channel structure to ensure uniform flow distribution. A micro-channel heat sink structure for active phased array antennas has been designed on the market now. The cross-section of the main entrance slot is stepped, the cross-section of the main exit slot is a right-angled trapezoidal shape, and there are non-equidistant...
