  • Low-loss solar heat collectors
    Patent number: 4078545
    Abstract: A solar-heat collector comprises a sheetmetal shallow box open on one side and receiving an absorber provided with passages traversed by a heat-transfer fluid. The absorber is provided with means for feeding the fluid to the passage and withdrawing the fluid therefrom for use. The feeding conduit means is in heat-transfer contact with the sheetmetal of the box so that an indirect exchanging relationship between the box and the fluid, as a preliminary heat exchanger, is established. A covering of a translucent material closes the open side of the box above the absorber.
