HEAT EXCHANGER
To provide a heat exchanger enabling expansion pressure generated when a heating medium in a heating medium flow passage is frozen to be easily released from an inflow port or an outflow port to outside.SOLUTION: A heating medium flow passage R2 of a heat exchanger 10 is formed to have a U-shape comprising an inflow passage 14a having an inflow port 15a, an outflow passage 14b having an outflow port 15b and a communication passage 13 communicating the inflow passage 14a with the outflow passage 14b. The heat exchanger includes a partition wall 12d that partitions a space between the inflow passage 14a and the outflow passage 14b and constitutes a wall part of the communication passage 13. Each of a flow passage cross sectional area A1 of the inflow passage 14a and a flow passage cross sectional area A2 of the outflow passage 14b is set larger than a flow passage cross sectional area A3 of the communication passage 13.SELECTED DRAWING: Figure 5
【課題】熱媒体流通路内の熱媒体が凍結した際に生じる膨張圧が流入口又は流出口から外部へ逃げやすい熱交換器を提供する。【解決手段】熱交換器１０の熱媒体流通路Ｒ２は、流入口１５ａを有する流入路１４ａと、流出口１５ｂを有する流出路１４ｂと、流入路１４ａと流出路１４ｂとを連通する連通路１３とを備えるＵ字状に形成されている。流入路１４ａと流出路１４ｂとの間を仕切るとともに連通路１３の壁部を構成する仕切壁１２ｄを備え、流入路１４ａの流路断面積Ａ１及び流出路１４ｂの流路断面積Ａ２は、連通路１３の流路断面積Ａ３よりも大きい。【選択図】図５
