The invention relates to a light condensation type solar heat collector and a flow control method for heat collecting liquid of the light condensation type solar heat collector, wherein the heat collector comprises a housing, a heat collecting part, a pulsating heat pipe heat absorber, a sleeve heat exchanger and a compound parabolic light condenser; the housing is equipped with a cover plate capable of transmitting sunshine; the heat collecting part is arranged in the housing, and comprises pipelines; the pipelines comprise an inlet liquid separating pipe and an outlet liquid collecting pipe which are separate; the pulsating heat pipe heat absorber is formed by a plurality of groups of evaporation sections and condensation sections which are arranged in a spaced mode; the sleeve heat exchanger comprises a sleeve housing and a condensation section, wherein the two ends of the sleeve housing communicate with the pipelines; each evaporation section is spanned on the compound parabolic light condenser; the heat collecting liquid forms a flowing path between the pipelines and at least one part of sleeve heat exchangers, and number of the sleeve heat exchangers, which are connected to the flow path, can be adjusted; and the liquid collecting liquid in the sleeve heat exchangers absorbs solar radiation energy reflected by the compound parabolic light condenser. The solar heat collector improves heat collecting efficiency of solar energy collection.
Description
technical field [0001] The invention relates to the field of utilization of solar radiation heat energy, in particular to a concentrating solar heat collector and a process control method for heat collecting liquid thereof. Background technique [0002] At present, the heat collecting liquid in the solar heat collector flows by natural convection or pump. The heat collector temperature and flow are passively adjusted, and it is impossible to dynamically adjust the operating state (heat collector temperature and flow) according to actual needs to adapt to changes in weather and usage requirements; and solar collectors usually use flat-plate heat-absorbing surfaces to absorb solar energy. Moreover, the temperature of the heat-absorbing surface is generally higher than that of the heat-absorbing tube, forming a high-temperature radiation surface and a heat leakage surface, which affect the heat collection efficiency. [0003] As an efficient heat transfer element, the pulsatin...
