TECHNICAL FIELD [0001] The present invention relates to a method of manufacturing a heat exchanger for cooling an electric device,

The present invention relates to a method of manufacturing a heat exchanger for cooling an electric device and a method of assembling a heat exchanger assembly for cooling an electric device. More specifically, The present invention relates to a method of manufacturing a heat exchanger for cooling an electric device and a method of assembling a heat exchanger assembly for cooling an electric device.

BACKGROUND ART [0002] As a countermeasure against environmental problems in recent years, the development of hybrid vehicles, fuel cell vehicles, electric vehicles and the like that utilize the driving force of a motor is getting more and more attention. The vehicle as described above is generally equipped with a PCU (power control unit) that regulates power supplied from a driving battery (e.g., a voltage of 300 V) to be supplied to a motor in a desired state.

The PCU includes electrical components such as inverters, smoothing capacitors, and converters. Since the electric elements generate heat by being supplied with electric power, a separate cooling means is necessarily required.

In the related art, an inverter in which a semiconductor module including a semiconductor device such as an IGBT and a diode is used is disclosed in Japanese Laid-Open Patent Application No. 2001-245478 (published on Sep. 10, 2001, entitled Cooling Device of Inverter) A heat sink is disclosed in Japanese Patent Application Laid-Open No. 2008-294283 (published on December 4, 2008, entitled "Semiconductor Device"), which is disposed in contact with a lower surface of a semiconductor element and is formed so as to heat exchange with a fluid flowing therein.

In the case of the single-sided cooling method, there is a limitation on the cooling performance, and the double-sided cooling method is designed to improve the cooling performance. In the double-sided cooling method, the element is inserted into the space between the heat exchangers. It is preferable that both the element and the heat exchanger should be pressed together in order to increase the heat transfer performance of the heat exchanger.

The double-sided cooling type heat exchanger as shown in FIG. 1 includes a tube 20 disposed on both sides of the electric element 10 and configured to allow a heat exchange medium to flow therein, and a heat exchanging medium 20 coupled to both ends of the tube, The heat exchanger is brazed so that the insertion space of the electric device is fixed, and then the electric device is inserted. Therefore, the inserting operation of the electric device is difficult.

In addition, when the interval between the tubes is increased to facilitate the insertion of the electric element, the heat exchanger is not squeezed and the heat exchange efficiency is lowered.

Therefore, it is necessary to develop a heat exchanger for cooling an electric device, which facilitates the insertion of an electric element and allows the element and the heat exchanger to be pressed together well.

SUMMARY OF THE INVENTION The present invention has been conceived to solve the problems as described above, and it is an object of the present invention to provide an electric device which is easy to insert an electric element and in which both sides of an electric element and tubes through which cooling water flows are in contact with each other, The present invention relates to a method of manufacturing a heat exchanger for cooling an electric device, and a method of assembling a heat exchanger assembly for cooling an electric device.

A method of manufacturing a heat exchanger for cooling an electric device according to the present invention comprises a tube formed by bending a certain point about a certain point so as to be in contact with both side surfaces in a height direction of an electric element arranged on a part of an upper surface side, A first header tank and a second header tank joined to and fixed to both ends of the first and second header tanks and the first header tank and the second header tank and including an inlet pipe through which the heat exchange medium is introduced and an outlet pipe through which the heat exchange medium is discharged, A method of manufacturing a heat exchanger for cooling, comprising the steps of: a) bending the tube at an angle so that the other end of the bend point is spaced apart; a first header tank; a second header tank; an inlet pipe and an outlet pipe Respectively; And b) a brazing step in which an inlet pipe and an outlet pipe are assembled in the first header tank or the second header tank, and a first header tank and a second header tank are respectively assembled and brazed at both side ends of the tube; And is formed to include a plurality of protrusions.

Also, in the component manufacturing step, a plurality of the tubes may be arranged, and the number of bending times of the tubes may be determined according to the number of the electrical elements arranged in the height direction.

Further, in the component manufacturing step, the tube may be bent at an angle of 5 to 10 degrees.

In addition, the tube is formed with a round portion protruding outwardly at a point where the tube is bent so that a height of a point where the electric element is mounted is higher than the interval between the tubes at a position where the electric element is placed in contact with both surfaces of the electric element .

In the brazing step, when a plurality of tubes are formed, a tube gap, which is a distance between the tubes, is at least two times longer than the length of the substrate fixing part protruded in one direction in the width direction of the electric element And can be combined with the first header tank and the second header tank.

In addition, in the brazing step, when the tubes are arranged in two rows and extended in the longitudinal direction, and are laminated in multiple stages by bending in at least two points in opposite directions to each other, the first header tank is connected to the inlet pipe and the outlet pipe An inlet pipe is connected to one of the first and second header tanks which are formed separately from each other and are connected to the first row of tubes and the first and second header tanks which are connected to the two rows of tubes, An outlet pipe can be coupled to one.

In addition, in the brazing step, the tubes having both ends connected to the first header tank and the second header tank may be eccentrically joined from the center of the first header tank and the second header tank in the height direction.

Also, a method for assembling a heat exchanger for cooling an electric device and an electric device for assembling an electric device includes the steps of: a) inserting an electric device between the tubes bending at an angle of 5 to 10 degrees; b) an electric element fixing step of fixing the electric element at a fixed position using the element fixing portion of the electric element; And c) a pressing step of pressing the tube and the tube so that both side surfaces of the tube come into contact with each other in a height direction of the electric element to closely contact each other; And a control unit.

Further, in the electric element inserting step, the connector of the electric element may be disposed on one side in the width direction of the tube, and the substrate fixing portion of the electric element may be disposed on the other side in the width direction of the tube.

In addition, in the electric element inserting step, when the tubes are two rows, the element fixing portions are disposed between the tubes, and the connector can be disposed outside the tubes.

When the tube is three rows in the electric element insertion step, the electric element inserted into the tubes located at both ends is disposed on the outside of the tube, and the connector of the electric element inserted in the tube located in the middle is positioned upward or downward It can be bent.

The method for assembling a heat exchanger assembly for cooling an electric device may further include inserting the electric element into a tube at the lowermost end when the tubes are bent in opposite directions at least two points and stacked in a multi- After the electric element fixing step and the adhesion step are performed, the electric element is inserted into the next stage tube, and then the electric element fixing step and the adhesion step can be sequentially performed.

The method of manufacturing a heat exchanger for cooling an electric device according to the present invention is a method for manufacturing a heat exchanger by which a tube is preliminarily bent and brazed so as to be spaced at a predetermined angle toward the other end of the tube, In addition, there is an advantage that it is possible to manufacture the heat exchanger in a desired shape by preventing the tube from being easily broken or ruptured during bending.

In other words, according to the characteristics of the material of the tube of the present invention, when the brazing is first performed after bending, the bending is performed after the bending is first performed in order to prevent the problem that the properties of the tube are easily changed.

Accordingly, the present invention is advantageous in that both side surfaces of the electric element and the tube through which the cooling water flows can contact each other, thereby effectively cooling the heat generated in the integrated circuit element.

In addition, the present invention includes tubes that are bent in opposite directions at least two points so as to contact both side surfaces in the height direction of the electric device, and are formed in multiple stages so that the both sides of the multi- The tubes can be brought into contact with each other to improve cooling performance and assemblability.

In other words, it is difficult to press the electric element and the tube when the interval between the tubes is widened so that the electric element can be inserted easily in the conventional double-sided cooling type heat exchanger. On the contrary, In order to solve the problem that it is difficult to insert the electric element by narrowing the gap, the present invention allows the electric element to be disposed in the space between the bent tubes without a process of inserting the electric element into a narrow gap, The cooling performance and the assemblability can be improved at the same time.

At this time, since the bending point is formed to include the rounded portion protruding outwardly, damage to the tube can be prevented in the course of bending the tube so as to contact both surfaces of the thin electric device having a thickness of about 4 to 5 mm .

Particularly, in the present invention, when one of the header tanks coupled to and fixed to both ends of the tube is formed as a separate type, or the baffle is provided in the space between the two rows and the remaining header tanks are integrally formed, It is possible to simplify the flow path configuration, reduce the space occupied in the vehicle, and facilitate peripheral component placement.

In addition, when the header tank is formed in a detachable shape, it is possible to assemble the elements in a row, thereby minimizing the possibility of deformation of the heat exchanger, which may occur due to tube bending more than twice.

The method of manufacturing the heat exchanger (1) for cooling an electric device of the present invention largely includes a component manufacturing step (S100) and a brazing step (S200).

The tube 100 is bent at a predetermined angle so that the other end of the bending point is spaced apart from the first header tank 210, the second header tank 220, (310) and an outlet pipe (320), respectively.

The tube 100 may be a tube 100 manufactured by extrusion of a plurality of partition walls in the longitudinal direction, or may be a tube 100 manufactured by folding or manufactured in a welded manner.
