PROBLEM TO BE SOLVED: To provide a pipe mat for heating and cooling capable of preventing an inconvenience due to a main pipe of a rectangular shape and also solving various problems brought about at the main pipe of a circular section. SOLUTION: The pipe mat for cooling and heating comprises a pair of main pipes MP each made of a synthetic resin and having a large sectional area, and a plurality of heat exchange pipes HP each made of a synthetic resin and having a small sectional area. Thus, both ends of the pipes HP are thermally welded to the pipes MP. In this case, a fluid supplied to the one pipe MP is supplied to the other pipe MP side via the pipes HP to cool or heat by a radiant heat of the fluid. The pipes MP are formed flat. Corners 22 formed in the pipes MP are rounded. Meanwhile, the pipes HP are thermally welded to a side face 13 for maintaining a thickness of the pipe MP. |
