Description

Heat exchanger

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat exchanger, and more particularly, to a heat exchanger for tightly connecting an inlet of a hose and a header tank.

Generally, the internal combustion engine compresses the supplied fuel and ignites and burns the fuel at high temperature and high pressure. Accordingly, a considerable amount of heat is always generated in the internal combustion engine. When the internal combustion engine is left unattended, the members constituting the engine such as the piston or the cylinder are overheated and can not perform the donation. Therefore, generally, a water jacket is installed around the cylinder of the engine and the cooling water is circulated therein to cool the overheated engine. If this cooling water is left as it is, the engine can not be cooled by boiling and a heat exchanger is installed in front of the vehicle, Or fan to cool the cooled cooling water.

The heat exchanger performing the above function is generally composed of a pair of header tanks made up of a header and a tank, a plurality of corrugated tubes having both ends of a pair of header tanks fixed and having a heat exchange medium flow path formed therein, .

Of these, an inlet is formed in the tank for introducing the heat exchange medium from the outside, and a hose may be installed in the inlet. At this time, generally, the inlet is inserted into the hose to be coupled, thereby fixing the hose.

1 is a cross-sectional view showing the combination of an inlet 30 and a hose 40 of a conventional heat exchanger.

Referring to FIG. 1, the heat exchanger constructed as above can circulate the heat exchange medium according to the operation of the engine. At this time, the heat exchange medium flows through the inlet port 30 through the hose 40, and the heat exchange medium can continuously or periodically apply a constant pressure to the inlet port 30 and the hose 40. [ When a constant pressure is applied as described above, the header 20 and the tank 10 are separated from each other, and the heat exchange medium can flow out between the header 20 and the tank 10.

When the gasket 50 is disposed in the resin tank 10 and the header engaging portion 11, the header 20 and the header engaging portion 11 are opened by the fluid pressure in the vicinity of the inlet 30, And the welded portion of the tube (not shown) may be broken. In this case, the same phenomenon may occur in an outlet (not shown) where the heat exchange medium flows out in addition to the inlet 30 through which the heat exchange medium flows.

On the other hand, a general heat exchanger as described above is specifically disclosed in Korean Patent Laid-Open Publication No. 2008-0019749 (entitled: Radiator coupling structure, applicant: Halla Air Conditioning Co., Ltd.).

Korean Patent Publication No. 2008-0019749

The heat exchanger 1000 also prevents the hoses 810 and 830 from escaping from the outflow inlets 411 and 431 when the heat exchange medium repeatedly exerts a force on the outflow inlets 411 and 431 and prevents the headers 610 and 630 And the tanks 410 and 430 are prevented from spreading, the endurance performance of the product can be improved. Particularly, as described above, the heat exchanger 1000 can prevent the welded portions of the header 610 and 630 and the tubes 410 and 430 from being damaged by the forces applied to the headers 610 and 630 when the headers 610 and 630 and the tanks 410 and 430 are opened .

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
