PURPOSE:To contrive a way to use effectively a high radiation performance and the sunlight, reduce the area required for installation of the subject heat exchanger and improve the efficiency in the installation thereof by providing a radiation panel vertically mounted from near the focal point of a concavely curved plate-like reflecting mirror to the center thereof and a solar battery panel located near the focal point of the reflecting mirror. CONSTITUTION:A radiation type heat exchanger is provided with a concavely curved reflecting mirror 10, a radiation panel 1 vertically mounted from near the focal point of the reflecting mirror 10 to the center thereof and a solar battery panel 5 set near the focal point of the reflecting mirror 10. The plane direction of the radiation panel 1 located closer to the reflecting surface of the reflecting mirror 10 than the focal point thereof is made to coincide approximately with the orbital plane of the sun, whereby the sunlight L1 entering the side of the radiation type heat exchanger are reflected by the reflecting mirror toward its focal point but does not reenter the radiation panel 1. The sunlight L1 reflected by the reflecting mirror 10 are made to enter the solar battery panel 5 and the solar energy of the directly entering sunlight L1 and of the reflected sunlight L1 is converted into an electric energy. |
