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.
