The key of solar light-heat power-generation is with gathering of solar energy, produce generating required temperature and energy, thereby the heat collector of solar light-heat power-generation system partly becomes the key of whole system, and it directly affects the economy of photo-thermal electricity transformation efficiency and cost of electricity-generating.
Existing solar hot water heat collector has various structures, generally can be divided into plate-type collector, vacuum heat collection pipe and heat pipe vacuum hot collector.The plate-type collector cost performance is higher, heat absorption heat exchange interface place is relatively mild, Energy distribution is more even, there is not focus in whole interface, overall heat exchange is more even, and service life is longer, so plate-type collector occupies consequence in the solar energy optical-thermal field, but the plate-type collector anti-freezing property is poor, is unsuitable for northern area and uses.Vacuum heat collection pipe is can low temperature resistant-30 Celsius, but the breakage rate of glass pipe fitting is higher, and low temperature usefulness is relatively poor, and the vacuum heat collection pipe of direct current mode has the danger of booster in summer.Heat pipe vacuum hot collector usefulness is better, but the danger that exists equally glass tube easily to split, and therefore, not yet occurs a kind of universality, the solar thermal collector that cost performance is higher at present.
The utility model content
The purpose of this utility model is to provide a kind of novel cavity-type solar collector in parallel.Has good freezing tolerance, higher thermal-arrest heat transfer effect and longer service life.
For solving the problems of the technologies described above, embodiment of the present utility model provides a kind of cavity-type solar collector in parallel, comprising: the many pipelines that parallel connection connects; Be close to the heat absorbing fins of the parallel slot type heat-absorbing chamber of conduct on pipeline surface, this heat absorbing fins surface is laid with coating for selective absorption.
Optionally, many pipelines are connected in parallel by header.
Optionally, the pipeline of parallel connection connection is two-layer.
Optionally, be close to the pipeline surface heat absorbing fins be shaped as undaform.
Optionally, the heat absorbing fins surface has the parallel diaphragm plate of polylith.
