[0045] The first embodiment of the present invention will be described below with reference to FIGS. 1-3 of the present invention. Figures 1A and 1B show top and front views of the heat sink, figure 2 is a cross-sectional view taken along line II-II in Figure 1, image 3 is a perspective view showing the mounting bracket that will be assembled to the radiator box.
[0046] The heat exchanger 100 in the first embodiment is a radiator for cooling the engine cooling water of the engine compartment of the internal combustion engine. The radiator 100 is an aluminum type radiator including a plurality of tubes 110 , a plurality of fins 120 , a pair of radiator boxes 140 , etc., wherein these parts are made of aluminum or an aluminum alloy and assembled and integrally fixed to each other by brazing.
[0047] The radiator 100 is a cross-flow type heat exchanger in which a plurality of tubes 110 are arranged horizontally, and includes a core 101 and a pair of radiator tanks 140 . In...

[0061] Figure 5 A double-type heat exchanger 100A is shown in which the condenser 300 is integrally assembled to the radiator 100 in the first embodiment described above.
[0062] The condenser 300 is an aluminum heat exchanger for refrigerant condensation in a vehicle refrigeration cycle. The basic structure of the condenser 300 is the same as that of the radiator 100, that is, the condenser 300 is a cross-flow type, including a core 301 having a plurality of tubes 310 and a plurality of fins 320, a pair of side plates 330, and a cylindrical one. On the tank 340.
[0063] A pair of cover members 34 are provided at both ends (upper and lower ends) of the upper water tank 340 for closing both ends. Each cover 341 forms a right extension 342, one side of which is brazed to the side plate 330, and a mounting pin 350 is formed on the other side of the extension. Covers 341 are provided at the upper and lower ends (four points) of the header tank 340 .

[0069] The following will refer to Figure 6A and 6B A third embodiment of the present invention is described in which Figure 6A A cross-sectional view of the nut portion 141 of the first embodiment is shown, while Figure 6B A cross-sectional view of the modified nut section is shown. The purpose of the modification is to reduce the size of the nut section.
[0070] Figure 6BThe nut portion 141 consists of two different metal materials. As in the first embodiment, the threaded portion 141b is formed on the inner surface of the cylindrical portion 141a. In addition, a screw 141d having threaded portions on inner and outer surfaces is screwed into the cylindrical portion 141a, wherein the metal material of the screw 141d is selected such that the breaking force of the screw 141d is higher than that of the cylindrical portion 141a. For example, the cylindrical portion 141a is made of aluminum or an aluminum alloy, while the screw 141d is made of iron or steel.
