Description
Technical field
The present invention relates to the heat utilization of solar energy, is the device of heat energy with conversion of solar energy, relate to utilize that solar energy heats, the utilization of the middle high-temperature of hot water, culinary art, generating, refrigeration, drying, particularly solar energy.
Background technology
The application technology of solar energy maturation is the low-temperature water heating utilization of solar energy, main employing vacuum glass Manifold technology is a heat energy with conversion of solar energy, technical at this kind, there is employing that heat pipe is inserted into glass tube with vacuum inside heat is delivered to the outside technology that obtains solar energy, and on the vacuum glass basis, further improve and the various devices of exploitation, wherein being provided with vacuum layer in the glass tube with vacuum is incubated, in the inside of vacuum layer selective coating is set solar energy is absorbed conversion, though the vacuum glass layer has well been realized insulation, selective coating has well been realized sun transformation of energy, but, heat energy utilization after it transforms gets up very uneconomical, as adopt existing method that water is fed directly to glass tube with vacuum inside and directly carry out heat exchange, but to winter just can't use, realized heat transfer in the winter time though adopt hot pipe technique, but increased cost, reduced the utilization rate of heat energy, present this technology is applied to the hot water of low temperature and uses, and can't realize the application of the middle high temperature of solar energy, as the application of solar generator;
The existing solar cooker that the middle high-temperature of solar energy is utilized, the main reflecting plate that adopts reflects sunshine, solar energy is directly focused on the kitchen range, realization is to the utilization of solar energy, this kind technology has well reached the middle high temperature of solar energy and has collected, but its heat energy accepting method is single, only is to adopt directly to place simple kitchen range in the above, and can't gathers on a large scale and utilize; Simultaneously also can't realize solar energy is collected so that night and overcast and rainy application;
The generation technology of high temperature in the existing technology solar energy mainly is to adopt tower, slot type, and butterfly, and groove type solar is business-like solar energy photothermal converter spare, outside main the employing is not glass tube, inside is the stainless steel metal pipe, and inside vacuumizes, and realizes the collection of solar energy; But this kind absorber price height has only the enterprise of minority can grasp its production technology; The main difficult technical of butterfly solar energy and tower type solar application simultaneously also is photo-thermal conversion solar energy switching device, tower type solar particularly, need carry out work in the interval of 600-1500 degree mainly due to photothermal converter, because stable work when metal device that high temperature adopted can't be grown, thereby tower solar power station just can't be long-term carry out work, thereby need the solar energy photothermal converter spare of high temperature be improved.
