関する。Detailed Description of the Invention (Industrial Field of Application) This invention is a battery stack which is formed by a plate-shaped unit cell cluster of multiple and modified types, and which is equipped with a cooling medium that is cooled by circulating cooling medium or flowing through it. The present invention relates to a fuel cell cooling body that cools a cell stack using a tube.

C) manufactured by Kerr IC, which has approximately the same coefficient of thermal expansion as the pallet 16
It consists of an assembly of a cooling board 4 and seven metal cold pipes 5 buried in the layer of the cooling board 4 and piped side by side, and one cooling bulb 5 for each of the two. The external cooling medium supply rail F7 (not shown) is connected at once.

せるように使用される。Further, as a method of embedding the cooling pipes 5 in the cooling board 4, there is a method of accommodating each cooling pipe 5 in a plurality of rows of pipe grooves formed on the mating surfaces of the cooling board 11 having two upper and lower sides; A plurality of U-shaped pipe grooves are formed on the surface of the cooling substrate 4, and each cooling pipe 5 is housed in the groove of the forceps. The cooling body 3 is used to remove heat generated by the battery by passing a cooling medium such as water through the cooling pipe 5 from the outside during steady operation of the fuel cell or FI'lh cell. When starting up the battery, hot water is passed through the cooling pipe 5 to raise the temperature of the battery body, which is in a low temperature state, to the starting temperature.

ツタパイプに抜ける構造となっている。Figure 5 is a perspective view of a conventional example showing a state in which a cooling pipe 5 is buried in a cooling board 4. It has a structure in which the cooling water that has entered passes through the cooling pipe 5 and exits to the other pipe.

間の伝熱性が著しく低下するようになる。However, with the above structure as it is, due to the machining accuracy of the pipe groove formed on the cooling board 4, the Xj method tolerance of the cooling pipe, etc., the entire circumferential surface of the cooling pipe 5 must be completely brought into close contact with the pipe groove surface of the cooling board 4. In reality, this is extremely true, and it is inevitable that a small gap will remain between the two. Moreover, the thermal resistance of the air gap is an order of magnitude thicker than that of the cooling board lI and the cooling pipe pipe 5. If even a small amount remains between them, the heat transfer between the cooling base 1 and the cooling pipe 5 will be significantly reduced.

Cooling board 4 filled with filler
There have also been proposals and implementations that aim to reduce the heat transfer resistance between the cooling pipe 5 and the cooling pipe 5.

祠を用いて調整をはかった。Conventional cooling bodies are manufactured by embedding cooling pipes in carbon material, but as mentioned above, the cooling pipes made of metal and carbon plates are in close contact due to processing accuracy and dimensional tolerances. In practice, it is extremely difficult to do this, and a small amount of air gap remains between the two, and this air gap significantly impedes heat transfer and lowers the iJ performance. The dimensional tolerances and coefficient of thermal expansion are different from the carbon material of the substrate ('), so we used a special filling hole to adjust the area where it came into contact with the carbon material.

Because it corrodes, a corrosive cover is removed before the carphone bracket is temporarily embedded, but this may be damaged during assembly of the cooling body, requiring repair work.

Since a II carbon plate is used for the subane (Fig. 4, 16) in the cell stack in which this cooling body is inserted, a metal alloy, such as an amber alloy material, whose coefficient of thermal expansion is approximately equal to that of the carbon material is used. A plurality of such pipe materials are used as the cooling pipes 23, arranged in parallel as shown in FIGS. The space 27 created between the frame plate 31 and the inner cooling pipe 23 is sufficiently filled with a filling material 28 made of metal powder and metal fibers having high thermal conductivity without leaving any space. The two ends of the longitudinal frame plate 31 of the cooling pipe 23 are welded or presser pieces are welded to prevent the filled metal powder or metal fibers from coming out.Inside the cooling pipe 23,
