PURPOSE: A heat exchanger is provided to prevent the deformation of the tube in the high pressure by supporting and dispersing the pressure. CONSTITUTION: A heat exchanger comprises a heat exchanger(130) and a pressure supporting part(150). The heat exchanger has the heat exchange with the exhaust gas passing through a path between adjacent tubes(110). The pressure supporting part is projected to the path. The pressure supporting part is contacted at least one of adjacent tubes. The heat exchanger and pressure supporting part are by turns formed. The exhaust gas passing through the path raises the turbulence. At least one part of the heat exchanger has the concavo-convex part. The protruding part of the pressure supporting part and the convex part of the heat exchanger meet at a right angle in the longitudinal direction. |
