摘要
介绍一种用于液体与制冷工质进行热交换的集成式微通道换热器。经测试,该换热器在满足压力损失限制和耐压性能的条件下,其强制对流换热系数达到5 000~10 000 W/(m2.K),紧凑度大于1 000m2/m3。该换热器具有广阔的应用前景和市场需求,用精密微细光蚀刻加工、材料表面处理以及精密固体原子扩散结合等生产技术可以实现大批量制造。
A new type integrated micro-channel heat exchanger applied for liquid and refrigerant heat exchange is researched. According to the experiment results, the heat transfer coefficient of the heat exchanger is between 5 000 and 10000 W/(m2 · K),compactness is greater than 1 000 m^2/m^3 while meeting the pressure loss,structural strength and stiffness conditions. The heat exchanger will have a wide range of applying future and meet the market needs. It's pointed out that mass production of the integrated microchannel heat exchanger can be achieved by applying advanced precision etching micro-ma chining, material surface treatment technology and precision diffusion bonding processing technology and so on.
