Such slightly protruding borders 38 and 39 are provided with connecting members 23.
Even if stretched wrinkles or cracks are generated during the pressing process, the wrinkles or cracks are covered and hidden by the heat transfer plates 15 and 16. Therefore, no particular inconvenience occurs even if the borders 38 and 39 are attached to the connecting member 23. The rims 38 and 39 may be provided with protrusions, and the heat transfer plates 15 and 16 may be provided with holes, and the protrusions and holes may be fitted to join the heat transfer plates 15 and 16 and the connecting member 23.

The fitting groove 12 may be curved. Even if the fitting groove 12 is curved, there is no problem in press working for bending the edges 13 and 14 of the heat transfer plates 15 and 16 to the groove bottom side 22. Because the heat transfer plate 15 that can be bent
The bend margin of the edge of 16 does not protrude long enough to continue to the other heat transfer plate facing the insertion groove 12 therebetween, but from the edge of the heat transfer plates 15 and 16. The protruding length is bent to form a groove wall 20 (21) on one side of the fitting groove.
, Ie, about half the groove width e of the fitting groove 12, and even if expansion and contraction wrinkles or cracks occur during press working, the heat transfer plate 15.1
