摘　　要：在针对余热吸附式冷管前期研究成果的基础上,以CaCl2-NH3为吸附工质对设计制作了一种新颖的吸附式冷管。该吸附式冷管主要由发生/吸附段、冷凝/蒸发段组成,两段间采用了毛细管柔性联接方式。对所设计冷管初步的实验研究表明,在热源温度200℃及环境温度23℃时,冷管最低制冷温度可达-2℃,在0℃左右可持续约60min,总的制冷时间约为160min。若热源温度提高,可使解吸周期缩短且吸附制冷时间保持不变,但并不能使最低制冷温度降低(反而有所升高)。A novel adsorption cooling tube is designed and manufactured, using CaCl2-NH3 as the adsorption working pairs. The adsorption module is mainly comprised of generator/adsorber, condenser/evaporator, between which the flexible connecting way of capillary is adopted. The primary experimental studies show that the adsorption cooling tube is able to be down to the lowest temperature of - ℃ under the conditions of the heat source temperature of 200℃ and ambient temperature of 23℃, and is able to sustain the cooling condition of around 0℃ about 60min, the total cooling time is about 160min. The rise of the heat source temperature can shorten desorption time and at the same time the adsorption time is not affected, however, which can not make the lowest cooling temperature decrease, and instead rise.
