新型叠片式油冷却器传热及综合性能的研究

探讨一种铝叠片和弓形折流板相结合的新型叠片式油冷却器,对其传热及综合性能进行了研究,并与螺纹管弓形折流板油冷却器进行了对比.试验结果表明,新型叠片式油冷却器热交换量较螺纹管弓形折流板油冷却器平均提高52.5％,单位压降热交换量较螺纹管弓形折流板油冷却器平均提高24.1％.在整体结构方面,其单位体积换热面积为螺纹管弓形折流板油冷却器的2.84倍,而材料总重量仅为螺纹管弓形折流板油冷却器的60.7％,说明新型叠片式油冷却器具有体积小、换热面积大、重量轻的优点；从经济效益角度看,新型叠片式油冷却器相比螺纹管弓形折流板油冷却器更加节省耗材成本,体现了新型换热器的高效性、紧凑性和节能性.

Study on Heat Transfer and Comprehensive Performance of a New Laminated Oil Cooler

The heat transfer and comprehensive performance of a new laminated oil cooler which is combined aluminum plates with segmental baffle in shell side was studied and compared with spiral tube and segmental baffle oil cooler.Experimental results indicated that the heat quantity of new laminated oil cooler improves about 52.5% than the spiral tube and segmental baffle oil cooler,and the heat quantity unit pressure drop increases about 24.1%.At the aspect of integral structure,its heat transfer area unit volume is 2.84 times as much as the spiral tube and segmental baffle oil cooler,and the total material weight is only 60.7% of the spiral tube and segmental baffle oil cooler,which shows the advantages of small volume,large heat transfer area and light weight;From an economic point view,the new laminated oil cooler saves more material cost than the spiral tube and segmental baffle oil cooler which embodies the high-efficiency,compactness and energy conservation of new type of heat exchanger.
