結果的に量産ができず、高価なものとなる。However, the conventional heat sink described above has the following problems due to the performance of the machine tool used and the manufacturing cost. In other words, it is not possible to form a complex groove shape in the plate material, it is impossible to form a narrow and deep channel in the plate material, and the shape of the groove formed in the plate material is limited to a planar channel, and it is not possible to form a narrow and deep channel in the plate material. It is not possible to create a flow path. Furthermore, it takes too much effort and time to form the flow path.
As a result, it cannot be mass produced and becomes expensive.

めコストの上昇を避けることができない。Alternatively, when manufacturing a heat sink, when joining the cover plate and the flow path forming plate by brazing, as shown in FIG. The plates 71, 72, 73, and 74 are joined with the soldering material 75 in between, but as shown in FIG. At the same time, there is a shortage of brazing material in this part, and a phenomenon of shrinkage due to shrinkage of the brazing material occurs during solidification, causing the joint 7
A gap 78 is likely to be formed between the parts 7 and 7, which increases the defect rate during manufacturing due to poor bonding, and causes leakage of cooling fluid due to causes such as pinholes occurring at the joint between the lid plate and the flow path forming plate. This tends to cause problems in pressure resistance at the joint between the lid plate and the flow path forming plate, and there is a risk of damage to the joint when high cooling fluid pressure is applied. In order to avoid these drawbacks, as shown in FIG.
Although countermeasures have been taken to reduce the number of defects to 5, an increase in costs cannot be avoided due to the increase in processing steps.

That is, in this heat sink, an artificial port and an outlet port are provided on either one of two surface plates, and a flow channel body in which a flow channel is formed by punching is bonded in a laminated manner between the two surface plates. Therefore, the fluid heat medium flowing in from the artificial port flows through the flow path formed by pressing the flow path body and flows out from the outlet port of the surface plate. During this time, the thermal energy conducted to the channel body through the surface plate is absorbed by the fluid heat medium and carried out to the outside of the heat sink.

付は端面を形成する。In manufacturing this heat sink by press punching, when stacking the flow channel plates, a brazing material is attached and heated to join them, but the punch radius that occurs on the cut surface of the press punched flow channel plates is The optimum value has been determined experimentally. That is, if the punch radius produced on the cut surface of the pressed channel plate is 0.1 mm to 0.5 mm, then
When flow path plates are laminated, brazing with a clean solder pool on the end faces forms the end faces.

、細(深い流路を構成することができる。When the channel body is composed of a single channel plate having a meandering channel, or when it is composed of a plurality of channel plates laminated and joined to each other and each having a meandering channel of the same shape, the inlet The fluid heat transfer medium that flows in from the port flows through the flow path and exits from the outlet port. When constructed from a plurality of channel plates, a narrow (deep) channel can be constructed.

トフィン型となるため、熱吸収効率がよい。Two types of press punching patterns are used to form a channel body, in which when two channel plates are stacked, the channel in one channel plate communicates with the two channels in the other channel plate. When flow path plates are alternately stacked and bonded, the fluid heat medium that flows in from the inlet port branches or merges each time it passes through the flow path and reaches the outlet port. In this case, the flow path has a so-called offset fin type, so that the heat absorption efficiency is good.

る毎に交互に用いればよい。In addition, the flow channel body is made by joining flow channel plates with different press punching patterns on both sides of a flow channel plate having a pair of small holes, and stacking them so that the flow direction of the heat transfer medium through the small holes is different. In the case of bonding, the fluid heat medium flows through the inlet port and absorbs heat through the flow path of the flow path plate formed by pressing out the flow path, and the flow path plate with small holes forms. The liquid then descends or ascends through the small hole and flows through a channel formed in another stamping pattern formed in the next channel plate. In this case, two types of press punching patterns may be prepared and used alternately each time flow passage plates with flow passages formed thereon are stacked.

While circulating around the body, heat is exchanged with a fluid heat medium of a different temperature that flows in from the inlet port of the other system,
It flows out from the exit port of each system. in this case,
A heat sink can act as a heat exchanger,
A heat sink can be used as a heat exchanger.

The material that has been punched is subjected to a surface modification treatment consisting of a surface roughening treatment and a subsequent cleaning treatment (step 51). After surface modification treatment is applied to the plate-shaped material, holes are formed in the inlet port and outlet port parts during the assembly process for joining each surface plate and the channel plate. At the same time, as a brazing material assembling process, a brazing material for bonding is assembled between the surface plate and the channel plates and between the channel plates (step 52).

1 or more, 0.1 mm to 0.5 mm (D range is sufficient, and if the plate thickness is in the range of 0.1 mm to 0.5 mm, then 0.11 mm or more) It can be seen that it is sufficient to form the punching radius R up to the length of the plate thickness.Here, only the punching radius R should be made larger in the area above the hunting area shown in Fig. 8, that is, relative to the plate thickness. As shown in FIG. 9, in the area beyond which the brazing is applied, a phenomenon occurs where the brazing becomes inconsistent and a depression 80 is likely to occur.Also, in the area below the hunting area shown in FIG. In a region where only the punching radius R is too small relative to the plate thickness, wax sag 76 and solder shrinkage 79 tend to occur as shown in FIG. 10.

比べて流路の形状を複雑且つ高精度に形成することがで
きる。The heat sink according to the present invention is configured as described above and has the following effects. That is, the heat sink according to the present invention includes two surface plates having an inlet port and an outlet port formed on at least one of them, and the surface plates are arranged in a laminated manner between the two surface plates and joined together, and there is no flow from the inlet port. Since the structure is composed of a channel plate having a channel formed by press punching that allows the inflowing fluid heat medium to flow out to the outlet port, it is necessary to form the channel in the channel plate without using the conventional channel. There is no need to form grooves in the channel plate by cutting. Therefore, the shape of the flow path can be formed more complexly and with higher precision than when the flow path is formed in the flow path plate by cutting.
また、流路の長さが長くなると、切削加工の場合は加工
時間がその長さに比例して長くなるが、プレス抜き加工
であると、−回のプレス抜き動作で形成できるので、加
工時間は流路の長さに関係なく短縮化される。In addition, as the length of the flow channel becomes longer, the processing time increases in proportion to the length in the case of cutting, but in the case of press punching, it can be formed in - times of press punching operations, so the processing time increases. is shortened regardless of the length of the flow path.
更に、プレス抜き加工の場合には、積層する流路板の枚
数を多くすればそれだけ流路の深さを深くすることがで
き、切削加工の場合のように深さに応じて加工時間が長
くなることがないと共に、切削加工の場合のように深さ
の限界があるというようなこともない。Furthermore, in the case of press punching, the depth of the channel can be increased by increasing the number of stacked flow path plates, and the processing time increases depending on the depth, as in the case of cutting. In addition, there is no limit to the depth as in the case of cutting.
切削加工やプレス成形加工の場合は、溝の形状が平面的
に限られていたので立体的な流路を作ることができなか
ったが、プレス抜き加工を施した流路板を複数枚積層す

ことができる。In the case of cutting or press forming, it was not possible to create a three-dimensional flow path because the shape of the groove was limited to a two-dimensional shape, but it is possible to stack multiple press-cut flow path plates. In some cases, the structure of the channel itself can be configured into a three-dimensional structure.

。In this way, in manufacturing this heat sink, the flow path plate forming the heat sink is formed by press punching, and then manufactured through the surface modification treatment process, assembly process, and bonding process, so that the flow path plate constituting the heat sink can be shortened. Since a large number of layers can be formed in one time, it has excellent mass productivity and can be manufactured at low cost.

If the length is 0.5 m, we know from experience that when flow channel plates are stacked and joined by brazing, a clean solder will form on the end face with a pool of solder on the end face, so there will be no chance of wax flowing out from the joint. The sagging phenomenon and the pulling phenomenon caused by the shrinkage of the brazing filler metal that occurs when the brazing filler metal solidifies does not occur, and no gaps are created in the joints. The defect rate during manufacturing is low, there is no leakage at the joints with the lid plate or channel plate, and there is no risk of damage to the joints even when high pressure is applied to the fluid heat transfer medium. do not have.
