The present invention relates to an automobile heat exchanger manifold, and more particularly, in a heat exchanger using a manifold at an inlet and an outlet of a refrigerant, by reducing the number of parts of the heat exchanger by integrating the manifolds of the oil inlet and outlet. Of course, since the pipe piping and the like is easy, and the manufacturing process can be simplified, the manufacturing cost is reduced, and the present invention relates to an automotive heat exchanger manifold having an effect of improving work efficiency.

Air conditioners of automobiles, which are internal parts of automobiles installed for the purpose of cooling or heating the interior of a car during the summer or winter, or to remove the frost from the windshield during the rain or winter, usually have both a cooling system and a heating system. Cooling, heating, ventilating, or windshield glass of a car interior by selectively introducing outside air or bet from outside or inside the car, and then cooling or heating the air and then blowing it into the car interior. Eliminate the frost of (Wind Shield Glass).

That is, the air conditioner of an automobile includes a blower (Blower) that selectively introduces and blows inside and outside air in a case communicating interior and exterior of the vehicle, and an evaporator which is heat exchangers for cooling or heating the air blown by the blower ( Built-in evaporator, heater, and temperature control door to adjust the ratio of the amount of air flowing into the heater, and selectively introduces indoor or outdoor air by the blower, and then introduces the air into the case. It is a device for cooling, heating or ventilating the interior of the vehicle by cooling or heating with the evaporator and the heater and selectively discharging the heater with the temperature regulating door via an evaporator installed in the chamber.

In such an air conditioner, heat exchangers such as an evaporator and a heater are disposed in a lateral direction on a blower path formed by an air conditioning case while forming a configuration of a circulation cycle through which heat exchange fluid (refrigerant or cooling water) is circulated. Iii) a heat exchanger which heats or cools the air blown through the blower with a heat exchange fluid, and heats or cools, in particular a stacked heat exchanger, arranged in the cross-sectional direction of the blower in the air conditioning case, A plurality of heat exchanging tubes communicating with each other to form a flow path disposed evenly on the cross section of the air passage therein, and a flow path interposed between the heat exchanging tubes to communicate with the heat exchanging tubes. At the top side, the flow path forms a heat exchange fluid circulation cycle such as a water jacket, expansion valve, or compressor. A plurality of heat exchange fins comprising two manifolds to which an inlet pipe or an outlet pipe connected to another configuration is coupled, and as an optional configuration, interposed between the heat exchange tubes to enlarge the heat transfer area of the heat exchange tube; It consists of such configurations.

According to this configuration, the heat exchangers 500 and 600 of FIG. 1 or 2 are introduced into the heat exchange fluid circulating through the heat exchange fluid circulation cycle through the inlet pipe of one side manifold for inflow and are distributed evenly along the heat exchange tubes. Then, the exhaust pipe is discharged through the outlet pipe of the other side manifold, thereby heat-exchanging air flowing into the vehicle interior between the heat exchange fluid and the heat exchange tubes to heat or cool the air discharged in the vehicle interior.

In a stacked heat exchanger having such a function, a manifold connected to another heat exchange fluid circulation cycle configuration outside of the air conditioner case by inlet and outlet pipes is usually formed by two plates having two tank parts formed side by side with tank holes at the upper end. Are joined to face each other, the tank portion on one side is extended, molded to the inlet for connecting the inlet pipe to the tank portion.

On the other hand, the laminated heat exchanger is transported in a state in which the inlet pipe and the outlet pipe are coupled to the manifold or mounted in the air conditioning apparatus, where the operator mainly carries the inlet and outlet pipes to carry or assemble the laminated heat exchanger.

In such a case, a bending moment is applied by an operator when transporting or assembling a laminated heat exchanger to each of the inlet and outlet pipes, and the coupling portion between the inlet and outlet pipes of each oil and discharge manifold is connected to the inlet and outlet pipes. Strong stresses are created by the bending moment.

However, conventional manifolds for stacked heat exchangers are relatively weak during transport or assembly because they do not have a structure that can reduce the moment of the inlet and outlet pipes or alleviate stress concentration. There is a problem that deformation or cracking occurs easily at the joint between the mouth, outlet pipe and the entrance. The problem of the stacked heat exchanger manifold is that the laminated heat exchanger manifold is a defect in the entire stacked heat exchanger formed by integrating the heat exchange tubes with the welding process, resulting in a problem of raising the manufacturing cost of the heat exchanger. It was.

As described above, the manifold for the conventional laminated heat exchanger has been a factor of increasing the manufacturing cost of the heat exchanger since the coupling part between the inlet and outlet pipes and the inlet part is easily deformed or damaged by a small external force during the assembling or transporting operation.

In general, a stacked heat exchanger of an air conditioner is configured to stack a plurality of tubes in multiple layers to allow a refrigerant to flow, and to increase a heat exchange effect by interposing a fin between them.

In this stack type heat exchanger, a manifold is used to connect the inlet and outlet pipes of the refrigerant. The manifold is interposed between the tubes and the three-dimensional press molded clad aluminum sheet, and then the pair Joined to form a bag shape, but facing the hole formed on both sides, it is to form a pipe connection to one side.

However, such a manifold is not only excessively expensive to manufacture the press mold, but also waste materials that are left after cutting the material are often inevitable, and waste of materials is inevitable. There are a lot of weak points, the joints are weak.

In addition, in another case, the connection between the tube and the outside or between the tube, should be manufactured by a forging or impact processing method, because it is difficult to manufacture, the productivity is greatly reduced, and accordingly disadvantageous in price.

In addition, after assembling the heat exchanger, the inlet pipe and the outlet pipe are inserted into the pipe connection to be welded separately.

The present invention has been made to solve the above problems, an object of the present invention is to configure the manifold used for the refrigerant inlet and outlet in the heat exchanger using the inlet and outlet of the refrigerant separately, the heat exchanger The purpose of this invention is to provide a heat exchanger manifold for automobiles, which reduces the number of parts, facilitates pipe piping, and thereby simplifies the manufacturing process, thereby reducing manufacturing costs and improving work efficiency. have.
