2. Description of the Related Art A technique of forming a hollow channel having an arbitrary shape by expanding one or both of metal plates by expansion is conventionally known, and is used in, for example, an air conditioner, a heat conductor of a refrigerator, and other wide fields. By the way, when a metal pipe is connected to a composite plate having a hollow flow path formed by expanding a pipe as described above, an opening opening at an end surface of the composite plate is expanded into a circle using a tool, and the circular opening is formed. In general, a structure in which one end of a metal tube is inserted and joined by brazing or the like has been adopted.

面化することはできなかった。However, in such a structure, the opening formed in the end face of the composite plate must be enlarged to have a circular cross section. Therefore, only one of the metal plates is expanded. It was difficult to keep the other metal plate flat, and in the vicinity of the end face of the composite plate, both metal plates had to be processed into semicircular shapes. Therefore, one side of the composite plate in the obtained piping member could not be completely flattened.

側にも膨出部３６が生じてしまうのである。[0004] For example, FIG. 14 shows a composite plate 30 in which two metal plates are adhered to each other, and only one of the metal plates is expanded to form an expanded tube portion 32, so that a semicircular cross section is formed in the composite plate 30. A pipe member in which a hollow passage having a rectangular shape is formed, and a metal pipe 34 is connected to an end of the hollow passage. In this piping member, in order to enhance the adhesion to the object to be cooled, the hollow channel itself is formed into a semicircular shape, and the composite plate 3 is formed.
However, even if one side of the metal pipe 34 is flattened, an opening having a circular cross section enough to accommodate the outer diameter of the metal tube 34 must be formed at the end of the composite plate 30. Must be plastically worked to form the bulging portions 36 and 38, respectively. That is, the bulging portion 36 is also generated on the flat surface side of the composite plate.

なかった。For this reason, the bulging portion 36 hinders the object to be cooled from being brought into close contact with the entire surface of one side of the composite plate 30. For example, as shown in FIG. When cooling both sides of the thin electric element 40 in parallel with a pair of common piping members and cooling by circulating a cooling medium, the metal tubes 34 are directed to the same side because the bulging portions 36 interfere with each other. And must be directed in different directions. In such a case, the cooling medium path for circulating the cooling medium through the metal pipe 34 cannot be simplified, and the cooling mechanism cannot be downsized. In particular, recently, there has been an increasing demand for intensively and efficiently cooling a small-sized element having a large calorific value by using a simple cooling system, but it has not been able to sufficiently meet the demand.

In addition, the bulging portion 4 is thinned to be easily broken, and a large triangular gap 48 is provided between the metal tube 46 and the opening.
Is difficult to hermetically seal, and is actually difficult to manufacture.

It is preferable to form a wick on at least a part of the inner surface of the wick. As a wick, it is easy to form a spiral or linear groove 10 on the inner surface of the tube 2 as shown in FIG. 8, but in addition, the inner surface of the tube 2 may be roughened or minute. Any wick conventionally used in the field of heat pipes may be formed, such as forming projections or minute recesses, or rolling and inserting a wire mesh sheet. Further, the wick does not have to be formed on the entire surface of the tubular body 2 and may be formed only on a necessary portion. For example, as shown in FIG. 9, the wick may not be formed on the inner surface of the insertion portion 8.

Is formed of a metal, the following method can be exemplified. First, two metal plates are prepared, and a release agent is applied to one of the metal plates by printing or the like to form a release agent layer forming a pattern of the hollow portion 4A. A sparingly soluble inorganic powder such as barium sulfate or a carbon powder may be used as the release agent, and may be used by being dispersed in a liquid such as polyvinyl alcohol or water during application. The solvent is removed by heating.

膨出部４を形成することも可能である。Next, the other metal plate is placed on the side on which the release agent layer is formed, and the two are diffusion-bonded by pressing and heating. At this time, since the particles of the release agent slightly bite into the surface of the metal plate, it is possible to adjust the roughness of the inner surface of the hollow portion 4A by adjusting the particle size and hardness of the release agent. When the joining is completed, the end corresponding to the release agent layer is pryed open to connect the pipe, and the composite plate is placed in a mold in which a depression corresponding to the bulging portion 4 to be formed is formed in advance, and both sides are restrained. Then, a swelling portion 4 is formed by injecting a high pressure fluid. And the plate 1
After cutting off the end to which the pipe was connected, the end of the opened hollow portion 4A was expanded with a jig to form an enlarged portion 6,
The insertion portion 8 of the previously formed tube 2 may be inserted into the opening 6A and brazed. However, this manufacturing method is an example, and the present invention is not limited only to this method. For example, an enlarged portion 6 is formed before inflation to connect the tubes 2, and a high-pressure fluid is injected through these tubes 2,
It is also possible to form the bulge 4.

As shown in FIG. 2, it is possible to completely flatten the surface of the plate 1 opposite to the bulging portion 4. Therefore, the plate 1
10 can be brought into contact with the object to be cooled.
As shown in (2), when the semiconductor element 20 to be cooled is sandwiched between two heat pipes, even if the semiconductor element 20 is thin, the pipes 2 are directed in the same direction without interfering with each other. In this state, it is possible to arrange two pipe members. If the tubes 2 can be arranged in the same direction as described above, the heat radiating means connected to the other end of the tubes 2 can be shared, and the space can be saved.

好適である。Further, since the cross section of the enlarged portion 6 is semicircular, it is not necessary to enlarge the opening of the hollow portion 4A to an unreasonable shape, and breakage and cracks hardly occur when the enlarged portion 6 is formed. Accordingly, a tube 2 having a large diameter can be used. In the case of a heat pipe, the present invention is preferable because it is necessary to make the pipe 2 thick to some extent in order to enhance the circulation of the working fluid.

In this case, the pipes 2 can be further separated from each other with the semiconductor element 20 interposed therebetween, and there is an advantage that the thin-film semiconductor element 20 can be used.

May be formed, and the pipes 2 may be connected to each other. The connection structure between the plate 1 and the tube 2 and other configurations may be the same as in the previous embodiment. In this case, the application is more suitable for cooling or heating an object by circulating a heat medium from one pipe 2 to the other pipe 2 than a heat pipe.
In that case, the end of the tube 2 is opened, and the working fluid is not sealed. If the working fluid is sealed in the pipe 2, it can be used as a heat pipe. However, it is necessary to consider the posture when using the heat pipe so that the working fluid is evenly distributed to the two pipes 2. .
