The present invention relates to a heat exchanger of the type consisting of a plurality of liquid flow tubes installed. Zigzag-shaped fins are arranged between these tubes, and cover the outer surface of each tube, pass between the tubes, and contact the zigzag fins in order to cool the liquid passing through each tube. Force the air to flow. A typical example of such a heat exchanger is an automobile radiator.

The joints between each part are usually soldered, which has poor clique characteristics and low fatigue resistance, resulting in weak strength. The present invention forms a main load-bearing joint made of welded metal or the like as a means of joining each pipe to the header plate at the contact area between the two or a part adjacent to the header plate, and furthermore, it The above-mentioned drawbacks are overcome by coating with a thin sealing material that seals small leak holes such as pinholes.

A zigzag-shaped fin 14 is disposed between each adjacent pipe and is attached to each pipe by conventional means such as welding, soldering, or brazing at the peak part, and connects each pipe to each other. It consists of.

They extend through the corresponding header plates as shown in the figure. The header plates 16 and 17 each include the header plate 1 shown in FIG.
7, it forms an integral inwardly extending flange 21. These flanges 21 define an opening 22 for receiving a tube end 23 of each tube 13. Flange 21
surrounds the tube receiving opening 22 and can therefore be referred to as a "peripheral flange".

即ち封止材２５を設ける。 The tube end 23 is connected to a first or main load-bearing joint 24
It is connected to the flange 21 by. A solder coating layer, ie, a sealing material 25, is provided on the atmosphere side of the joint between the tube 13 and the flange 21.

することができる。 If the radiator or heat exchange tube 10 is constructed of metal, the main load-bearing joint 24 is preferably formed by welding. The term "welding" as used here has a broad meaning; it involves heating metal parts together,
It means to join by fusing with each other. If the heat exchanger is made of plastic, the plastic parts can also be heated and welded together.

主荷重担持継手即ち第１継手２４を形成した

力を分散させる機能をも果す。 Most of the load between the header plates 16 and 17 is carried by the main load-bearing joint 24, but the sealing material 25 is also carried, especially if it is formed by soldering or brazing. , also performs a load-bearing function. However, the main purpose of the sealant 25 is to seal leakage holes such as cracks, crevices, pinholes, etc. that may occur during the manufacturing process of the heat exchanger or during subsequent use. In any case, the main purpose of the sealing material 25 is to cool any leakage holes that may occur during manufacturing or subsequent use; It also serves to disperse some of the forces, in particular those caused by changes in the internal pressure acting on the inner wall of the tube 13 and by changes in the temperature of the liquid.
