径が小さいものとなされている。FIG. 4 shows a second embodiment of the present invention. Here, the difference from the case of the first embodiment is that the former of the first header tubular body (11) and the second header tubular body (12) of the header member (10) is the former one. This is because the diameter of the tubular body portion for the first header (11) is larger than the diameter of the latter tubular body portion for the second header (12). Along with this, one of the two union screws (14) (14) has a large diameter and the other has a small diameter.

ができるという効果を奏する。Effect of the Invention As described above, the heat exchanger according to the present invention comprises the meandering flat tube having a plurality of fluid passages, the first header tubular body and the second header tubular body parallel thereto. It is provided with an integrally formed header member made of aluminum extruded shape and a channel-shaped side frame member fitted on both right and left sides of the meandering flat tube, and the inlet side end of the meandering flat tube is the same. One end of the flat tube is inserted into a long hole in the upper portion of the first header tubular body and connected to the header tubular body, and the outlet side end of the meandering flat tube is located on the same side of the flat tube. In the heat exchanger inserted into the elongated hole at the bottom of the second header tubular body and connected to the header tubular body, the first and second header tubular bodies of the header member are plates. And the hexagonal part for stopping rotation at the sides of the tubular body for both headers. A union screw consisting of a male thread and a male thread is attached, and the side wall of the channel-shaped side frame member fitted to one side of the meandering flat tube and the header section is fitted with a generally U-shaped union screw when viewed from the front. 2 up and down through the connecting wall
A hexagonal hole is provided in the bottom wall part of each fitting part, and a hexagonal part for preventing union screw rotation is fitted into the hexagonal hole, and the plate-like connecting part of the header member is provided with a side frame. It is fixed to the connecting wall part of the member with a screw, and the header for introducing the refrigerant and the discharge header are constituted by one member, so the work of fixing the header is very easy and heat exchange The inlet / outlet dimensions of the heat exchanger, that is, the dimensions of the connection portion of the inlet / outlet pipe can be set very easily and reliably, and when the heat exchanger is attached to, for example, an automobile,
Since the connection pipe can be attached to the side of the heat exchanger, the connection pipe does not get in the way, it is easy to set the attachment position of the heat exchanger with respect to the automobile, etc., and due to the vibration of the automobile after attachment, There is no fear that the two headers will be horizontally displaced to the left or right, or will be disengaged, and the durability is excellent and the weight can be reduced.
