2. Description of the Related Art As a heat exchanger for an internal combustion engine of a construction machine or the like, one having a plurality of module cores arranged between a pair of upper and lower main tanks is known. In this heat exchanger, a plurality of openings are arranged in parallel in a pair of main tanks facing each other, each module core is composed of a large number of tubes and fins, and both ends of the tubes are connected to a sub tank. A pipe for connection is projected on the end surface of the sub tank,
The pipes are liquid-tightly connected to the respective openings of the main tank via packing. In the heat exchanger having such a plurality of module cores, each core can be manufactured in a relatively small size, so that the heat exchanger is easy to manufacture and has good mass productivity. Moreover, the maintainability of the heat exchanger is excellent. That is, it is sufficient to replace only some of the cores when a crack or the like occurs in the cores.

However, it is extremely troublesome to connect a plurality of such module cores to the main tanks at the upper and lower ends at the same time while maintaining liquid tightness. This is because in order to liquid-tightly connect the pipe protruding from the end of the sub-tank and the opening of the main tank through the packing, the inner and outer diameters of the packing should be fitted to the opening and the pipe, respectively. It is necessary to form it with a certain amount of interference. That is, it is necessary to make the inner diameter of the packing smaller than the outer diameter of the connecting pipe and make the outer diameter of the packing larger than the opening of the main tank. Therefore, even when connecting only one module core and the tank, it is necessary to press-fit each connecting part at that time. Moreover, since it is necessary to press-fit a plurality of module cores at the same time, a lot of time and labor are required for the connecting work. Therefore, the present invention has the following configuration in order to solve the above problems.
