基于冷凝余热控温的制冷机柜设计
Design of Refrigeration Cabinet Based on Condensing Heat Temperature Control
摘要
Abstract
Based on the liquid cooling needs of the radar signal processing extension,a refrigeration cabinet with condensation waste heat temperature control is developed.Combined with the working parameters such as ambient temperature,condensation temperature and cooling water temperature,the working principles of"compression cooling"and"forced air cooling"modes are designed,and the structural parameters of the condensing heat exchanger are calculated.By optimizing the condensation side structure and pipeline layout,the volume and weight of the refrigeration cabinet are reduced,and the ability to regulate the water supply temperature by condensation heat recovery is realized,the environmental adaptability is improved,and the fluctuation of the water supply temperature is suppressed.The test results show that the cooling capacity of the refrigeration cabinet in the forced air-cooling mode is 20.35 kW,the cooling capacity in the compression cooling mode is 20.66 kW,and the water supply temperature is(20±1)℃.This design can continuously provide low-temperature circulating cooling water,meeting the needs of water cooling and efficient heat dissipation of the signal processing extension.关键词
