PURPOSE:To provide a heat exchanger which has an excellent strength against pressure, easiness to be transported on a vehicle and a freedom of the tube pitch by providing the open ends of the tube with an independent tank respectively which is connected to another tank or a plurality of tanks through a nozzle. CONSTITUTION:Cooling water enters a tank 2A from a pipe and part of the cooling water goes to a tank 2J through a tube 6 and other cooling water goes into a tank 2B through a nozzle 31 from a tank 2A and enters the tank 2A through the tube 6. The cooling water which entered the tanks 2J and 2K goes into a tank 2L and tank 2M from the nozzle 31, and then enters tanks 2C and 2D through the tube 6. The cooling water collects to a tank 2E through the nozzle 31 and enters a tank 2N through the tube 6. The cooling water cooled by a heat exchanger goes through the nozzle 31 of the tank 2N and returns again to the water jacket of an engine by a connected pipe. Since tanks 2A-2N are provided on the sides of the open ends 61 and 62 of each tube, each tank can be small and its strength against pressure is raised because of a small area to receive pressure. |
