PURPOSE:To prevent a decline in heat collecting efficiency due to latent heat loss and perform an efficient heat exchange by a method wherein a partition of a flow equalizing device forms an enclosed space between the partition and a light receiving sheet, and also a water guide plane. CONSTITUTION:A water supply/equalizing device, where water as a heating medium is supplied to the inner surface of a light receiving sheet 5 and the water flow is equalized, consists of a water supply device and a tongue-shaped flow equalizing device which has a partition at a position near the light receiving sheet on the downstream side of the water supply device. The water as heating medium discharged from the water supply device flows on the inner surface of the light receiving sheet 5 and comes in contact with the partition of the flow equalizing device, or falls down to the partition of the flow equalizing device after coming in contact with the light receiving part 5. The water as heating medium supplied is guided up to the front edge of the flow equalizing device by the inner surface of the light receiving sheet 5 or the partition and is spread after passing through the front edge, and falls down, contacting with the inner surface of the light receiving sheet 5. The heating medium after falling down is collected by a hot-water collecting device. |
