Abstract
An apparatus for collecting solar energy wherein a heat exchange array of plastic or the like is protected against damage by excessive heat buildup. The array is housed in a normally closed chamber having a portion transparent to solar rays and the chamber is periodically vented by means responsive to heat expansion of the enclosed array. The invention permits substantial cost reductions in solar heat exchanges; particularly of the type adapted to heat buildings, swimming pools and domestic water systems.
Claims8
A solar heat collector having in combination:
- a solar absorbing heat exchanger for exposure to solar radiation;
- a housing enclosing said exchanger and having a movable wall portion of a material transparent to solar radiation;
- means for the support for said exchanger within said housing,
- said support means permitting heat induced expansion of a portion of said exchanger in respect to said housing;
- means fixing a portion of said exchanger to said housing to prevent movement is respect thereto;
- and
- means responsive to heat induced expansion and contraction of said exchanger for separation of said movable wall from said housing,
- whereby to permit ambient air to circulate within said housing with resultant cooling of said exchanger.
