  • Publication number: 20200292252
    Abstract: Disclosed is a heat exchanger that includes a tubular outer wall and partition walls that partition an inner side of the outer wall into heat medium passage cells and gas passage cells extending in an axial direction of the outer wall. The heat exchanger exchanges heat between a liquid heat medium flowing through the heat medium passage cells and a gas flowing through the gas passage cells. The ratio of the number of the heat medium passage cells to the number of the gas passage cells is 1:3 to 1:6.
