ABSTRACT:
A solar collector converts solar radiation to heat energy over a specified surface area and collects the heat energy by trickle feeding a heat transfer fluid over a trickle feed absorber surface having improved absorber surface area to volume ratio. The elements of the solar collector include a glazing first layer for receiving and passing incident solar radiation over the specified surface area and an impervious backing layer spaced from the glazing first layer. The absorber layer is sandwiched between the glazing first layer and backing layer with the glazing first layer and backing layer contacting the absorber layer on opposite sides. The absorber layer is a layer of fiber material defining capillary channels and spaces in the absorber layer between the glazing first layer and backing layer. The fiber material absorber layer such as a dark synthetic felt layer is formed with a radiation absorbing color and defines a relatively high surface area to volume ratio trickle feed absorber surface through the absorber layer. A heat transfer fluid inlet channel is coupled to an open top end communicating with the absorber layer for trickle feeding heat transfer fluid by gravity through the capillary channels and spaces of the absorber layer. A heat transfer fluid outlet channel is coupled to an open bottom end communicating with the absorber layer for delivering heated fluid. The solar collector may be formed in a rigid plate configuration or in a flexible sheet configuration so that the solar collector can be rolled up for storage.
