ABSTRACT:
A solar heat collector, wherein an absorber plate is mounted in a box member provided on the upper surface thereof with a transparent sheet. The surface of the absorber plate is subjected to a selective absorption surface treatment, and a transparent heat trap is bent into continuous V-shapes and disposed between the transparent sheet and the absorber plate. The transparent heat trap is formed of an ethylene fluoride series resin film having a film thickness of 1 to 100 .mu.m, having a degree of crystallinity of 35 to 55% and being transparent for the infrared rays as well as for the solar rays. With this arrangement, heat losses due to convection, radiation and conduction are suppressed at the same time, so that a high heat collecting efficiency can be secured.
