ABSTRACT:
Illustratively, a portion of a thin sheet of high thermal conductivity material is wrapped in tight thermal communication about the external surface of a working fluid conduit. A hinged male die presses part of the portion of the sheet into a semi-cylindrical female mold. The die is removed and the fluid conduit is placed in the semi-cylindrical sheet. Another hinged mold, with the aid of a drawing up mechanism bend the balance of the sheet portion into thermal communication with the hitherto exposed conduit surface. Beveled mold edge also exposes a seam for joining the sheet portion to the balance of the sheet.
