目前,国内使用非常广泛的动力用空气压缩机的中间冷却器,绝大多数为水冷式,其结构以紧凑型为主。但是这种管片式中冷器是60年代初期设计的,换热率不到0.60kcal/m~3·k,额定工况下的总传热系数低于50kcal/m~2·h℃,而且结构笨重,如3L-10/8型空压机中冷却器芯子重达40kg,体积大,易锈漏。为此,机械工业部通用机械研究所针对中冷器当前存在的问题,新设计了一批中冷器试件,于1984年在通用所中温组合风洞上进行了3L动力用空气压缩机中间冷却器试验,共测试了八个试件,其中六个为实物中间冷却器(由南京压缩机厂制造)。试件结构包括两件原型(冷却片材料
At present, the domestic use of a very wide range of power with the air compressor intercooler, the vast majority of water-cooled, its structure is compact. However, this tube-type intercooler was designed in the early 1960s with a heat transfer rate of less than 0.60 kcal / m 3 · k and a total heat transfer coefficient of less than 50 kcal / m 2 · h ° C under rated conditions, And the structure is bulky, such as 3L-10/8 air compressor cooler core weighing 40kg, large size, easy rust leak. To this end, the General Machinery Institute of Machinery Industry for the current intercooler existing problems, the new design of a number of intercooler test pieces, in 1984 in the GM combination of wind tunnel 3L power with air compressor in the middle Cooler test, a total of eight specimens were tested, of which six were physical intercooler (made by Nanjing Compressor Factory). The specimen structure consists of two prototypes (fin material
