面でも問題があった。The cooling-perforated copper plate manufactured by the above-mentioned conventional method has difficulty in performing sufficient bonding over the entire surface of the bonding surface by brazing, and therefore has sufficient airtightness and watertightness. It was difficult to obtain it stably. In addition, the strength of the joint was limited by the strength of the brazing material, and was not sufficient. For these reasons, it is difficult to reliably obtain products of stable quality economically, and there are also problems in terms of cost and yield.

である。In order to achieve the above object, the present invention employs the following means. That is, as shown in FIG. 1, a groove 3 to be finally formed as a cooling hole is formed on the surface of at least one of the pair of copper plates 1, and an austenitic stainless steel pipe 5 is formed in the groove 3. After being arranged and canning together with the other copper plate 2, diffusion bonding is performed by a hot isostatic pressing device to be integrated, and then the austenitic stainless steel pipe is cooled by removing it in a sulfuric acid solution. This is a method for producing a copper plate with holes.

することが可能である。The cooling hole finally obtained does not necessarily have to be opened at the end face of the integrated copper plate, but may be opened at the surface of the integrated copper plate. In such a case, the groove 3 is not formed up to the end of the copper plate 1 but is formed halfway, and a hole is formed at the start and end positions of the groove 3 or at a position on the copper plate 2 opposite to the position. Can be an opening.

テンレス鋼製とした。In the method of the present invention, the austenitic stainless steel pipe 5 is provided in the groove 3 for the following reason. That is, when the copper plate 1 and the copper plate 2 are diffusion-bonded by a hot isostatic pressing device, in order to make these bonding strengths sufficient and ensure airtightness and watertightness,
It is preferable to increase the temperature and pressure of the hot isostatic pressing process. However, when these conditions are increased, the grooves 3 to be the cooling holes are deformed and disappear during the hot isostatic pressing. This is because copper plates 1 and 2 are used during hot isostatic pressing.
Is carried out and the inside of the groove 3 is evacuated. Therefore, in order to prevent such deformation and disappearance, an austenitic stainless steel pipe 5 having strength at a higher temperature than the copper plate is provided for supporting the groove 3. This pipe was made of austenitic stainless steel because other steel materials may be used as long as the pipe has higher high-temperature strength than the copper plate.

When used in the form of pipe material, when it is removed with sulfuric acid, if it is used as a rod or wire, it will be removed by melting only from its end face, requiring a very long time. In contrast, if pipe material is used, the dissolution proceeds from the entire inner surface of the pipe material, and the pipe material is removed in a direction in which the thickness of the pipe material becomes thinner, which enables removal in a short time. is there.

却効率が低下することになるからである。[0009] Sulfuric acid was used to remove austenitic stainless steel pipes because other solutions, such as hydrochloric acid and nitric acid, dissolve the copper plate together with the pipes. This is because only the result that only the copper plate was dissolved and the copper plate was not dissolved was obtained. The purpose of removing the austenitic stainless steel pipe is to increase the cooling efficiency. That is, if the austenitic stainless steel pipe remains, a layer having poor thermal conductivity exists between the copper plate and the cooling medium, and the cooling efficiency decreases.

At this time, in order to increase the dissolution rate of the pipe, the sulfuric acid solution was supplied into the pipe using a metering pump. As a result, the pipe could be removed in about 24 hours. After removing the pipe, the integrated copper plate was cut and the cross section was observed. As a result, it was confirmed that only the pipe was completely removed and the copper plate was not dissolved. Further, it was confirmed that the copper plates were sufficiently bonded by a bending test.

点がある。As described above, according to the method of the present invention, since the formation of the groove to be the cooling hole is performed on the surface of the copper plate, its shape and size can be freely selected. An austenitic stainless steel pipe is placed in the groove and diffusion bonding is performed by a hot isostatic pressing device, so that only the pipe is dissolved and removed with sulfuric acid without deformation or disappearance of the groove, so that a complete cooling hole can be obtained. An open copper plate can be obtained. In addition, the joining of the copper plates is sufficient, and a cooling hole having airtightness and watertightness can be reliably obtained. In addition, since the method of the present invention employs a method in which a pair of copper plates are diffusion-bonded by hot isostatic pressing, the pressure during the processing is applied from all directions, so that even a complicated shape can be deformed. Therefore, there is an advantage that not only a flat copper plate but also a complicated shape such as a bent copper plate can be manufactured.
