Since they are fitted, the diameter of each tank must be larger than the width of each heat transfer tube, and as a result, the wall thickness of each tank can be unnecessarily increased in order to secure pressure resistance. Requested. Further, when fitting the open end of each heat transfer tube to the peripheral wall portion of each tank, it is necessary to bore a plurality of radial slots along the axial direction of the peripheral wall of each tank. It was difficult to perform the drilling work accurately. In addition, when trying to assemble each heat transfer tube with fins in each tank, the thickness of each heat transfer tube, the height of each fin, and the pitch accuracy of each radial slot are strictly controlled. There is a problem that has to be.

け作業が簡単になる。In the present embodiment configured as described above, the width directions of the opening portions at both ends of each heat transfer tube 20 to 20 are set to both tanks 10,
Since the inner peripheral wall portions of the metal pipes 10 are aligned with each other in the axial direction, the diameter of each metal pipe can be reduced. Therefore, it is possible to increase the pressure resistance of each tank 10 while reducing the wall thickness of each metal pipe, and to reduce the weight of each tank 10. Also, both joint members 4
Since 0 and 50 can be attached to both metal pipes P2 and P n-1 in various directions, the work of attaching the joint members 40 and 50 is simplified.

In addition, since the axial length of each metal pipe is short and the axial direction of each metal pipe matches the longitudinal direction of each elongated hole portion, each end face of each metal pipe has high flatness with high accuracy. It can be easily processed while maintaining. Further, since the thickness of each heat transfer tube 20 to 20 and the variation in height of each fin 30 to 30 are absorbed by the burring holes of each metal pipe, the thickness of each heat transfer tube and each fin. The cost tolerance can be reduced by increasing the tolerance of the height.

る。Further, when the heat exchange fluid flows into the joint member 40,
The heat exchange fluid is radiated by the fins 30 to 30 so that each communicating metal pipe of the left tank 10, each heat transfer tube communicating therewith, and each communicating metal pipe of the right tank 10 communicating therewith. Alternately flow from the lower side to the upper side and flow out from the joint member 50. In such cases,
An appropriate flow of the heat exchange fluid that matches the heat exchange characteristics can be created only by changing the number of communicating pipes of the metal pipes of each tank 10.

る熱交換器。1. A pair of longitudinal tanks which are vertically installed in parallel with each other with a space provided therebetween, and the tanks are horizontally juxtaposed to each other so as to have a width orthogonal to the longitudinal direction of each tank. In a heat exchanger including a plurality of flat cross-section heat transfer tubes fitted together and fins respectively interposed between the heat transfer tubes, each heat transfer tube has an axis extending in the width direction. Each of the tanks is configured by stacking a plurality of sealed metal pipes so that their axes are parallel to each other, and one end opening of each heat transfer tube faces each one end opening. One of the sealed metal pipes of the one tank is fitted to the axial peripheral wall of each sealed metal pipe, and the other end opening of each heat transfer tube faces the other end opening of each sealed metal pipe of the other tank. Axial circumference And one end of one sealed metal pipe located at one end in the stacking direction of the sealed pipes and one end of the sealed metal pipe located at the other end in the stacking direction of the sealed pipes. A heat exchanger characterized in that an opening for introducing the exchange fluid into the tank and an opening for leading out the heat exchange fluid in the tank are provided respectively.
