Abstract
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat exchanger, and more particularly, to a heat exchanger capable of reinforcing deformation of a header of a heat exchanger by joining a reinforcing member to a certain region of a header inside a header tank.
Description
The present invention relates to a heat exchanger, and more particularly, to a heat exchanger capable of reinforcing deformation of a header of a heat exchanger by joining a reinforcing member to a certain region of a header inside a header tank.
A radiator of a vehicle radiates part of the heat generated in the internal combustion engine through the cooling water into the atmosphere. In the internal combustion engine, a very large amount of heat is generated in the course of ignition and combustion of high-temperature and high-pressure gas.
Therefore, unless the internal combustion engine is cooled, various components including the cylinder and the piston are melted or torn due to overheating, thereby causing damage and breakage.
The radiator is provided with a jacket for receiving cooling water around the cylinder of the internal combustion engine and circulating the cooling water into the jacket so that the cooling water absorbs heat generated from the engine to cool the engine.
However, since the cooling water also absorbs heat from the engine for a long time and can no longer absorb heat from the engine at a high temperature, a device for cooling the cooling water is required. The radiator circulates the high- It is a device.
In addition, the air conditioner for adjusting the air inside the car to a comfortable temperature is installed in the currently released vehicle. In such an air conditioner, a high-temperature, high-pressure gaseous refrigerant is compressed into a liquid refrigerant by radiating heat to the condenser, and then the low-pressure refrigerant is supplied through the evaporator to the inside of the automobile. In this way, predetermined heat dissipation must also be performed in the condenser.
In addition, an oil cooler for cooling the engine oil and the transmission oil is installed inside the vehicle, and an intercooler is installed depending on the type of the engine.
As described above, since each of the devices requires sufficient heat radiation, they are installed in front of the engine room so as to cool them, so that they can be radiated smoothly.
The heat exchanger is composed of a pair of headers having a plurality of tubes through which the heat exchange medium flows and spaced apart from each other by a predetermined distance so as to fix both ends of the tubes and a pair of tanks respectively coupled to the pair of headers, Respectively.
Further, when a tube is coupled to a pair of conventional headers, a tube insertion hole is formed to connect the tube to the header, and the tube insertion hole is protruded at a predetermined interval in an inward direction in which the header and the tank are coupled.
Here, the tube is coupled to the protruded tube insertion hole, and the tube is protruded and coupled to the inside of the header tank to heat the heat exchange medium, heat is exchanged by the fin interposed between the tubes. The heat exchanger may be used for various purposes depending on a heat exchange medium flowing therein.
However, the tube is expanded / contracted due to the repeated temperature change of the heat exchanger, which may cause deformation due to the thermal stress.
Such deformation due to thermal stress often occurs at a junction portion between the header and the tube. When such deformation is severe, there arises a problem that gold is formed in the tube itself or distortion or twisting of the header occurs , The internal heat exchange medium may leak.
When the thickness of the tube material is increased in order to solve the above problems, the production cost and weight of the heat exchanger are increased and the productivity is lowered.
As another method for solving the above problem, a conventional heat exchanger (Japanese Patent Laid-Open No. 2007-163124) shown in Fig. 1 has a structure in which both ends of a tube are inserted into a header 30, And the reinforcing
In this case, the reinforcing
SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems, and it is an object of the present invention to provide a method for manufacturing a heat exchanger, which can prevent cracks in a tube insertion hole and a tube- And a heat exchanger capable of preventing deformation or twisting of the header due to a low temperature difference.
Particularly, it is an object of the present invention to improve the durability of a header by using a simple method of joining a reinforcing member to a region where a temperature difference is generated without increasing a thickness of a header or a tube, and after the reinforcing member and the header are assembled, And to provide a heat exchanger capable of increasing productivity by brazing.
It is also an object of the present invention to provide a heat exchanger which is freely adjustable in the size of the formation of the reinforcing member, so that it can be freely applied to a portion where reinforcement of the header is required.

Accordingly, the heat exchanger of the present invention can prevent the cracks of the tube insertion hole and the tube joint portion by deforming or twisting the header due to the temperature difference between the high temperature and the low temperature of the heat exchange medium by joining the reinforcing member to a certain region of the header inside the header tank There is an advantage that it can be prevented.
Particularly, in the heat exchanger of the present invention, the durability of the header can be increased by using a simple method of joining the reinforcing member to the region where the temperature difference is generated without increasing the thickness of the material of the header or the tube. After the reinforcing member and the header are assembled together, There is an advantage that productivity can be improved by brazing joint.
Further, the heat exchanger of the present invention is advantageous in that the size of the reinforcing member can be freely adjusted, so that it can be freely applied to a portion where a header is required to be reinforced.
