Heat exchanger
专利汇可以提供Heat exchanger专利检索，专利查询，专利分析的服务。并且PURPOSE:To make it possible to prevent an air flow from leaking and to make repair of root portions by providing plates extending between sheet metals and fins in the direction which is substantially rectangular to the core part ventilation direction and filling up gaps formed between the sheet metals and fins. CONSTITUTION:A corrugated fin type heat exchanger has two hot water tanks 2 and 14, sheet metals 8 and 80 which cover the hot water tanks, and core parts. The core parts are formed by a large number of tubes 10 both ends of each of which are inserted into and connected to both hot water tanks 2 and 14 an fins 12 mounted on these tubes 10. A thin and long plate 10 such as a bent portion 16 which extends in the direction substantially rectangular to the ventilating direction 4 of the core part and fills up gaps between the sheet metals 8 and 80 and the fin 12, is provided between the sheet metal 8 and the fin 12. Since the tip end of the bent portion 16 makes contact with the end portion 12a of the fin 12, it is possible to prevent the air flow from leaking and further when the leak is generated from the root portion, soldering of a part D is carried out from the direction C by a line solder and thus the repair of the root portion is made possible.，下面是Heat exchanger专利的具体信息内容。
