The present invention relates to a three-piece type header pipe assembly, a method for manufacturing the same, and a heat exchanger using the same. More particularly, in a heat exchanger comprising a header pipe assembly in which upper and lower heat exchange tubes are spaced apart from each other at regular intervals, The header pipe assembly may be coupled between the first and second header pipes to compensate for the disadvantage that the header portion and the tank portion need to be modified each time when changing the size or position of the communication hole formed for the movement of the heat exchange refrigerant between the refrigerant passages. By constructing the flange beam-shaped bulkhead, only the bulkhead is modified when adding or deleting communication holes and other purposes, so that unnecessary modification of other parts is unnecessary, thereby reducing manufacturing costs and improving productivity. 3-piece type header pipe assembly and its manufacturing method It relates to a heat exchanger using the same.

The heat exchanger is formed by connecting a plurality of tubes between a pair of header tanks and installed on a flow path of a cooling or heating system to exchange heat with external air when the heat exchange medium supplied through the inlet of the header tank passes through the tube. It is an air conditioner that cools or heats the space in the room by conducting and guiding the discharge to the Europipe through the outlet.

The heat exchanger is also applied to an automotive air conditioning system. In particular, a condenser for condensing the heat exchange medium of the air conditioner is installed in front of the engine compartment, and a radiator for cooling the engine's cooling water is sequentially installed behind the condenser. However, even though these condensers and radiators are heat exchangers with similar structures, the condensers and radiators are manufactured separately, so layouts are required according to the manufacturing process. Therefore, the installation cost is high and these condensers and radiators have to be installed when installing them in automobiles. There was a disadvantage that the installation man-hours increased.

Therefore, since the tanks must be brazed to the headers, the number of manufacturing and assembly can be increased, thereby decreasing productivity, and the first and second heat exchangers are spaced apart by protrusions at the center of the headers, thereby increasing the width of the integrated heat exchanger. There was a disadvantage of being enlarged.

In addition, since the lower ends of each of the tanks are brazed to the header, the brazing parts are four places.

Also, in general, automobiles are equipped with various heat exchangers in order to match room temperature conditions to passengers and to cool the heat generated by the engine of the vehicle.

The heat exchanger is equipped with an evaporator for cooling the interior of the vehicle, a heater core for warming the interior of the vehicle, a radiator for cooling the engine of the vehicle, and a condenser for condensing the refrigerant risen in the evaporator.

In addition, when the engine mounted on the vehicle is a diesel engine, the charge air cooler that cools the charge air flowing into the diesel engine, and the transmission oil for cooling the heat generated in the mission when the vehicle mounted mission is automatic. Cooler, etc. are mounted.

Since the heat exchanger is mostly made of aluminum and plastic, the brazing method is used when the aluminum is composed of aluminum, and the brazing method is not used when the plastic and aluminum are mixed. Use a gasket made of rubber or silicone to prevent this.

Most of the heat exchangers have a pipe, which is a passage through which fluid enters, a fin for exchanging heat between the fluid and the outside air, a tube through which the fluid flows between the fin and the fin, and the tube and the fin at regular intervals. It consists of a header for fixing and a tank connecting the header and the pipe and allowing fluid to be distributed to each tube.

The tank of the heat exchanger may be made of plastic and assembled with an aluminum header.

In particular, in the case of a heat exchanger using a conventional two slab type header pipe assembly, the header pipe assembly is combined with the header portion and the header portion to which the heat exchange tube is directly connected as described above to form a closed space. The tank unit is made of two or more refrigerant passages.

As shown in the drawing, A is a header pipe assembly 103 in which two tubes are joined in a longitudinal direction, and B is a double oil (W). A plurality of members of the shape are coupled so as to correspond to each other to form a plurality of flow paths of the header pipe assembly 104, C is to form a header pipe assembly 105 formed with a plurality of flow paths using a single plate material When forming a communication means 102 for mutually communicating heat exchange refrigerants between the plurality of refrigerant passages (100, 101), or when modifying the existing communication means or adding and deleting the other members consisting of a header and a tank Due to the need to modify the entire header pipe assembly, there is a disadvantage in that the manufacturing cost increases and productivity is lowered.

The present invention has been made to solve the above problems, an object of the present invention comprises a conventional two slab (Slab) type header pipe assembly consisting of the first, second header pipe and the partition wall therebetween, the By modifying the size and location of the refrigerant communication hole formed inside the header pipe assembly, the existing disadvantage of modifying the header part and the tank part every time is solved, thereby modifying the refrigerant communication hole and other members only by processing in the partition without additional modification of the remaining parts.

FIG. 4 is a first exemplary view showing a heat exchanger according to the present invention. As shown in the drawing, the three-piece type including the first and second header pipes 20 and 21 and the partition wall 30 described in FIGS. An example of a heat exchanger to which the header pipe assembly 10 is applied is shown.

Header pipe assemblies 10 and 10 'are coupled to upper and lower ends of a plurality of heat exchange tubes 50 having fins 51 interposed therein, and the header pipe assemblies 10 and 10' are partition walls 30. 30 '), the first and second header pipes 20, 21 (20', 21 ') are bent in the' C 'or' c 'on both sides of the partitions (30, 30') are mutually symmetrical Combined to form an inlet 11 and an outlet 12 through which the heat exchange refrigerant S is introduced.

The position at which the heat exchange refrigerant S is introduced or exited may be changed out of both sides of the header pipe assembly 10.

For reference, the first and second header pipes 20, 21, 20 ′, 21 ′ of the header pipe assembly 10, 10 ′ to show the flow order and the interior of the heat exchanger or the partition 30. Although not shown separately, it will be apparent that the first and second header pipes 20 and 21 (20 'and 21') are all present for the fabrication of a complete heat exchanger.

The inlet manifold 60 forms an inlet hole 61 at one side to allow the heat exchange refrigerant S to flow therein, and a manifold hole communicating with the inlet 11 formed in the header pipe assembly 10. (62) is formed in the side surface. In addition, the outlet manifold 63 forms an outlet hole 64 so as to be communicatively coupled to the middle of the second header pipe 21 to discharge the heat exchange refrigerant S.

6 is a third exemplary view showing a heat exchanger according to the present invention, FIG. 7 is a fourth exemplary view showing a heat exchanger according to the present invention, and FIG. 8 is a fifth exemplary view showing a heat exchanger according to the present invention. 6, 7 and 8 illustrate examples of a heat exchanger that forms a four-path refrigerant path using a three-piece type header pipe assembly 10 and 10 ′ according to the present invention.

First, referring to FIG. 6, a plurality of communication holes 34 are fixedly spaced in the header pipe assembly 10 coupled to an upper end of the heat exchange tube 50 through which the heat exchange refrigerant S is first introduced and exited. It is formed spaced apart, the separator 70 for controlling the flow path of the heat exchange refrigerant (S) is formed therein.

In addition, the separator 70 and the diaphragm 31 should be brazed separately.

In detail, the header pipe assembly 10 includes first and second header pipes 20 and 21 and partition walls 30, as described in FIGS. 2, 3, 4, and 5. 5, the header is coupled to the top of the heat exchange tube 50, unlike the communication hole 34 is formed in the partition wall 30 'of the header pipe assembly 10' is coupled to the bottom of the heat exchange tube (50) It is formed in the partition wall 30 of the pipe assembly 10.

The partition 30 has the effect of dividing each of the first and second header pipes 20 and 21 into a front end and a rear end by protruding the separator 70 on both sides of the partition 31.

The communication hole 34 is formed at the rear end side opposite to the front end of the header pipe assembly 10 to which the inlet and outlet cap 40 is coupled among the front end and the rear end divided by the separator 70.

In other words, the partition wall 30 is coupled to the inlet and outlet cap 40 at the front end, the separator 70 is protruded at the stop, and after the communication hole 34 is formed on the surface, in detail below again The end cap 43 to be described is coupled to the other end.

End caps 43 are coupled to both ends of the header pipe assembly 10 'coupled to the bottom of the tube 50 to seal the corresponding portions.

Based on this, when the heat exchange refrigerant (S) flow path sequence of FIG. 6 will be described in detail, the heat exchange refrigerant (S) is introduced into the front end of the first header pipe (20) through the inlet hole (41) of the inlet and outlet cap (40). After the first header is blocked by the separator 70 and does not go to the rear end, the first header pipe 20 'is moved on the heat exchange tube 50, and the first header which has not reached just before the heat exchange tube 50 again. It moves to the rear end side of the pipe 20. After the movement, it flows to the second header pipe 21 through the communication hole 34 formed in the partition 30, and passes through the heat exchange tube 50 and the second header pipe 21 'in communication therewith, Again flows through the heat exchange tube 50 to the front of the second header pipe 21 is discharged through the outlet hole 42 of the inlet and outlet cap 40.

In addition, in FIG. 7, in FIG. 6, the two separators 70 protruding from both sides of the partition wall 30 are symmetrical to both sides of the diaphragm 31 and are not formed at the same position with respect to the partition wall 30. This shows that the user can be freely asymmetrically formed at the desired position, and the number thereof can be increased or decreased.

In addition, FIG. 8 is an inflow hole 61 into which heat exchange refrigerant S is introduced instead of an inflow and outflow cap 40 which is coupled to one side of the header pipe assembly 10 to inflow and outflow heat exchange refrigerant S in FIGS. 6 and 7. ), But the inlet manifold 60 is used to form a manifold hole 62 on the side which is in communication with the first header pipe 20 without being in communication with the second header pipe 21.

In addition, the outlet manifold 63 is also used, which is coupled to the second header pipe 21 as shown in FIG. 5, and the communication hole 34 is based on the partition wall 30 of the header pipe assembly 10. It is to be formed on the opposite side formed.

Referring to the flow sequence of the heat exchange refrigerant S of FIG. 8, the heat exchange refrigerant S moves to the first header pipe 20 through the inlet manifold 60, and is stopped by the partition wall 30. After the flow through the heat exchange tube 50 flows into the first header pipe 20 ′, and then again through the heat exchange tube 50 through the communication hole 34 of the first header pipe 20 and the partition wall 30. Go to the 2 header pipe (21).

As described above, although the embodiments of the present invention have been described with reference to the accompanying drawings, the present invention is not limited thereto and is intended by those skilled in the art to which the present invention pertains. Various modifications and changes may be made without departing from the scope of the appended claims.

As described above, in the case of the conventional two slab type header pipe assembly, the heat exchange tube is combined with a header part directly connected to the tank part to form a closed space, thereby making two or more refrigerant flow paths. When the header pipe assembly is configured as the first and second header pipes and the partition wall coupled therebetween, the header part and the tank part must be modified every time the size or position of the refrigerant communication hole formed in the header pipe assembly is changed. By solving the existing shortcomings, the modification of the refrigerant communication hole and the addition and deletion of other members can be easily performed only by processing in the partition wall without additional modification of the remaining parts, thereby reducing the manufacturing cost and improving productivity due to easy installation. .
