IPC: F24S10/75
Filed: 1981-06-03
Abstract: PURPOSE:To facilitate the working of a concave groove and at the same time enable to keep the tightly contacting state between a heat collecting plate and a heat collecting tube against abnormal pressure in the heat collecting tube by a structure wherein the cross sections of the heat collecting tube and of the concave groove, in which the heat collecting tube is housed, of the heat collecting plate are made to be elliptic. CONSTITUTION:The cross section of the concave groove 7 formed longitudinally on the metallic  heat collecting plate 6 is made in the form of an ellipse, the major axis of which is normal to  the direction of the opening part of the concave groove 7. The cross section of the metallic heat collecting tube 8, which is fitted in the concave groove 7 and within which heat transfer medium flows, is also made to be elliptic. When the heat collecting tube 8 is fitted in the concave groove 7, a part 8a of the tube 8 protrudes from the opening part of the groove 7. After the heat collecting tube 8 is fitted in the concave groove 7, the protruded part 8a of the heat collecting tube 8 is pressed flat until a flatten part 8b is formed in order to deform the heat collecting tube 8 so as to fill the concave groove 7, resulting in tightly contacting the heat collecting tube 8 with the concave groove 7. Owing to the structure as mentioned above, even if abnormal pressure is produced within the heat collecting tube 8, said pressure acts for the heat collecting tube 8 to increase the contact pressure with the concave groove 7.
