Description
(1) technical field
The utility model relates to a kind of many faceted pebbles solar thermal collector, belongs to solar energy techniques application.
(2) background technology
Solar thermal collector is the core component of Solar Enercy Fission Geyser, and at present, many plate solar collector thermal energy converters adopt tube-sheet type mostly.Tube-sheet type thermal energy converter is by welding, it to be combined the absorber plate and the collection point copper pipe that scribble coating for selective absorption.The heat that absorber plate absorbs divides by collection that heating agent in copper pipe is mobile to be delivered to heat in heat storage water tank, and the major defect that tube-sheet type interchanger collection divides copper pipe: collection point copper pipe and absorber plate contact area are very little, the a large amount of heat that has caused absorber plate to absorb can not effectively be delivered in the thermal medium in collection point copper pipe, thereby a large amount of heat energy that cause absorber plate to absorb waste; In order to obtain better terrestrial solar radiation, current flat plate collector must with building southern wall facade installation at a certain angle, be unfavorable for the design of architecture-integral, there is certain potential safety hazard simultaneously, install if be close to the southern wall facade of building, the solar irradiation obtaining can reduce again.
(3) summary of the invention
The utility model is in order to make up the defect of prior art, a kind of contact area that had both improved thermal medium and absorber plate is provided, reduce heat waste, can many faceted pebbles solar thermal collector that can not reduce solar irradiation be installed because the existence of plate core makes whole heat collector be close to the southern wall facade of building again.
The utility model is achieved by the following technical solution:
A kind of many faceted pebbles solar thermal collector, comprise plate core, glass cover-plate and housing, the junction of glass cover-plate and housing is provided with glass capsulation adhesive tape, plate core lower end is provided with heat-insulation layer and metal backing, it is characterized in that: described plate core comprises absorber plate, plate core top layer is coated with solar selective absorbing coating, plate wicking surface is evenly provided with several prismatic that becomes matrix to arrange, prismatic and plate core shape have a certain degree, acute angle place adopts elliptic arc transition, forms the heating agent cavity interconnecting between two prismatic.
Wherein:
Described prismatic and plate core shape have a certain degree, and acute angle place adopts elliptic arc transition, has greatly increased plate core collector area, and has matched with solar incident angle, make the utility model can be close to the southern wall facade of building and install.
Described prismatic becomes matrix to arrange at plate wicking surface, two absorber plates relatively and in X-axis and Y direction misplace and weld together mutually, between prismatic, form the heating agent cavity interconnecting, whole like this sheet material inside all can form heating agent cavity and interconnect, the whole area of heating agent and absorber plate can directly be contacted, greatly improve the heat transfer area of absorber plate and thermal medium, the heat energy that absorber plate is absorbed is transmitted in heating agent and goes rapidly, has improved instantaneous heat collection efficiency and has reduced heat loss.
Described absorber plate adopts the punch forming of mould Integratively, and through vacuum magnetron sputtering coating film technique or electroplating black chromium technique solar selective absorbing coating on plated surface outside.
The beneficial effects of the utility model are: simple in structure, easy to use; Low and the operating efficiency of cost improves, and can be close to (or inlaying) and build southern wall facade and install, and has reduced potential safety hazard; Both the contact area that had improved thermal medium and absorber plate, has reduced thermal loss, makes heat conduction rapider, easy to utilize again because heating agent and absorber plate directly contact.
