PURPOSE:To give an ability of absorbing not only solar energy but also the heat of air to a heat collector for raising its heat efficiency in a hot water supplier utilizing solar energy by making up the heat collector from a heating pipe and an L-shaped fins. CONSTITUTION:In a solar energy-powered hat water supplier, a refrigerant condensed in the condenser 3a of a heat exchanger 3 is converted into a low-temperature and low-pressure one by an expansion valve 4 and then introduced into a heat collector 1, where it is gasified into regrigerant gas, converted into a high-temperature and high-pressure one by a compressor 2, and returned to the condenser 3a. Then, hot water receiving heat from the heater 3b of the heat exchanger 3 is sent through a temperature regulator valve 7 to a hot water storage tank 5, where the temperature of the hot water is raised by circulation by means of a circulation pump 6. In this case, the heat collector 1 is made up by thrusting heating pipes 8 through the vertical faces 9a of L-shaped fins 9 and fixing them in such a way that a proper interval 10 is provided between the horizontal faces of the fins 9 for allowing air to pass. Then, a black paint is coated on the surfaces of the fins 9. |
