Abstract

PURPOSE:To simplify the panel manufacturing step by a method wherein a foamed styrol for use in reinforcing is filled in a clearance generated around a heat exchanging pipe and the clearance is filled with secondary foaming of foamed styrol generated by heating operation in the panel manufacturing operation. CONSTITUTION:A heat exchanging pipe 3 is fitted to a pipe fitting groove 2 formed at least at one surface of a themal insulating base material 1 to arrange the heat exchanging pipe 3, a radiator plate 4 is adhesively and integrally arranged to the pipe 3 on the thermal insulated base material 1. In the teral insulated panel with the heat exchanger, reinforcing foamed styrol 7 is filled in the clearance 6 provided around the pipe 3, the styrol 7 fills the clearance 6 under a secondary foaming generated by heating operation to be applied for during manufacturing of the panel. With this arrangement, as compared with that a filling material such as urethane is fed and foamed separately after operation, the manufacturing step is more simple and it is possible to decrease the manufacturing cost of the thermal insulated panel.

Problems to be Solved by the Invention However, in any of the above cases, it is unavoidable that a void 6 is inevitably formed around the heat exchange pipe 3. That is, the cavity 6 is formed between the heat exchange pipe 3 and the header pipe 3, as shown in FIG. 2A, for example.
It occurs in a fairly large amount around the connection part with a and the intersection of the heat exchange pipes 3 and 3 as shown in B of the same figure, and only in a single heat exchange pipe 3 as shown in C of the same figure. Even in the portion where it exists, it occurs at least in the upper part between it and the groove 2. Thus, the occurrence of such voids 6 partially deteriorates the compressive load resistance of the heat insulating panel, which is particularly harmful in applications such as floor heating panels. Not only the above empty section 6
The presence of this impairs the heat insulating performance of the panel itself, and as a result, the efficiency of the heat exchanger is reduced.
