Design of liquid cooling compartment with a cooling capacity of 200 kW
This paper proposes a design scheme for a liquid cooling compartment to ad-dress the heat dissipation issues of the power modules and microwave components inside the specialized vehicle's antenna array.The design is based on the working environment,structural characteristics,and performance requirements of the specialized vehicle.The proposed scheme divides the liquid cooling compartment into three parts:the refrigeration system,the water supply system,and the maintenance channel.The refrigeration system employs a"parallel expansion"design with two refrigeration units to achieve a cooling ca-pacity of 200 kW.The water supply system features a"mutual backup"dual-loop pump design to ensure a continuous circulation of cooling water.The maintenance channel follows a"single-channel centralized layout"design to facilitate component installation and maintenance.The paper thoroughly discusses the operational principles,system compo-nents,and modes of operation of the liquid cooling compartment,focusing on key technol-ogies such as water supply temperature control.Performance validation tests were conduc-ted using the enthalpy difference method.The test results indicate that the cooling capacity of the liquid cooling compartment is 201.5 kW,with a maximum power consump-tion of 95.5 kW,both meeting the performance requirements.
