Abstract

PURPOSE: To obtain the high cooling efficiency of a heat collecting device by a method wherein even if the surface of a heat collecting plate and the surface of a heating unit are not flat, both of the plate and the unit are reliably made to adhere closely to each other. CONSTITUTION: A cooling medium circulating pipe 2 is bonded to the surface of a heat collecting plate 1 by brazing. The plate 1 has a space 3 on its central part and the pipe 2 is provided on the plate 1 in such a way as to make one round along the space 3. A large notch 4 is formed in the plate 1 between the entrance and exit sides of the pipe 2 and moreover, a multitude of small notches 7 are formed in the plate 1 at proper intervals from the outer and inner peripheral edges of the plate 1 toward the pipe 2. By forming the notches 7, the deformation at the time of the production of the plate 1 can be corrected and at the same time, even if the surface of a heating unit is not flat, it becomes possible to make the plate 1 contact closely to the heating unit and as the heat collecting area of the plate 1 is increased, the cooling efficiency of a heat collecting device is improved.
