Solar heat collecting and transporting device

Abstract

Solar heating is an environment-friendly and effective means for reducing building energy consumption which is increased day by day and enabling a city and a village to enjoy the same heating comfort, but an existing heat collecting way is large in heat collecting area, low in heat transfer efficiency and low in building integration flexibility. The invention provides a novel solar building heating, heat collecting and transmitting system without mechanical work consumption. The solar building heating, heat collecting and transmitting system mainly consists of a composite paraboloid light condensation heat collector, a loop-circuit heat pipe and a user hot water system, wherein the loop-circuit heat pipe is formed by connecting multiple evaporators in parallel. According to the solar building heating, heat collecting and transmitting system provided by the invention, the composite paraboloid light condensation heat collector is adopted, and efficient collecting of solar energy is realized through pure light condensation; efficient collecting of heat is realized through the multiple evaporators of the loop-circuit heat pipe which are connected in parallel; solar heat driving without the mechanical work consumption is realized by utilizing capillary suction forces of capillary cores of the multiple evaporators of the loop-circuit heat pipe; efficient, long-distance and multi-angle transmission of high-load solar heat energy is realized by utilizing the circulation phase change of a working medium in a closed space, and thus efficient collection and transmission of low-temperature solar energy are realized.
