<p>PROBLEM TO BE SOLVED: To provide a jointed metal heat plate, where a joint surface is tightly closed at a high level. SOLUTION: A heat plate 1 is provided, where a U-shaped groove is molded at the joint surface of an aluminum member 3, which is combined to a flat joint surface of an aluminum member 4 to form a heating medium flow path 2. Here, an annular groove 6 is provided along the entire circumference of the joint surface of the aluminum member 3 so as to enclose the heating medium flow path 2, the joint surface of the aluminum member 4 is provided with an annular protruding part 7, and with the annular protruding part 7 combined with the annular groove 6, the joint surface is forging-pressed to form the thermal medium flow path 2 inside, while a fastening part 5 of high-density sealing characteristic is so formed as to enclose the thermal medium flow path 2.</p> |
