Abstract

The utility model provides a flat plate type solar vacuum collector, which is characterized in that the flat plate type solar vacuum collector includes a dielectric layer, an outer surface layer and an inner surface layer, wherein the dielectric layer is a closed cuboid or a cube, circulation ports are respectively formed at the upper and the lower parts of the cuboid or the cube, the outer surface layer and the inner surface layer are connected and fixed with the dielectric layer through a bracket, a solar selective coating layer is applied onto the inner surface layer of the dielectric layer, and vacuum layers are formed between the dielectric layer and the outer layer, and between the dielectric layer and the inner layer. The utility model solves the difficult problems that the pollution can not be discharged through a round vacuum tube, the cleaning is inconvenient, and the heat efficiency is reduced after a long use time. The utility model can be installed conveniently, and the heat efficiency is higher; and if a plurality of flat plate-type solar vacuum collectors are connected, the collectors not only can be used as a large solar collector but also can be placed at the top part of a building to be used as a solar water heater, and also can be used as a thermal insulating layer. The manufacturing cost of the flat plate type solar vacuum collector is only 70 percent of that of a round vacuum tube heat collector.

Description

A kind of plate type solar vacuum collector

Technical field

The utility model relates to the receiving system of solar energy, specifically a kind of plate type solar vacuum collector.

Background technology

The heat collector of existing solar water heater has tube-sheet type, and vacuum tube and U type tubular type are no matter the sort of type heat collector all is fixed installation.The device that had occurred multiple heat collector from motion tracking sun operation afterwards again, these device solves the problem of subsolar point, make heat collector absorb solar energy to greatest extent, but its complex structure, wind loading rating is poor, the cost height, and fault increases, shortcoming such as after cost height are so be difficult to promote the use of.

Using maximum solar water heaters at present is circular vacuum tube collector, accounted for 85% the market share nearly in the whole nation, the maximum drawback of vacuum pipe solar water heater be clean very difficult, especially in vast outlying rural area, mountain area, the place of water quality inferiority, the service life of circular vacuum tube collector and efficient will be had a greatly reduced quality.

Summary of the invention

The purpose of this utility model provides an a kind of difficult problem that has solved circular vacuum tube collector fouling, cleaning, blowdown, the plate type solar vacuum collector that cost is lower.

The technical solution of the utility model is: the plate type solar vacuum collector is made of dielectric layer, extexine and endosexine; Dielectric layer is an airtight cuboid or a square, respectively open a circulation port at the upper and lower of this cuboid or square, extexine and endosexine are connected and fixed by support and dielectric layer, scribble the solar selectively dope layer in the dielectric layer endosexine, form vacuum layer between dielectric layer and extexine and endosexine.

Several plate type solar vacuum collectors can be placed on the support at certain angle of inclination, using flexible pipe to be together in series up and down is one group (every group can connect polylith plate type solar vacuum collector), every group is coupled together side by side to get final product again.

Plate type solar vacuum collector of the present utility model has increased an interface in the lower end, this interface can be done down the circulation input interface and use, and the double again blowdown interface of doing uses, and has solved the difficult problem of circular vacuum tube collector fouling, cleaning, blowdown.And cost is lower, and just taking a 50cmx50cm plate type solar vacuum collector is example, and its daylighting area is 2400 square centimeters (49x49), uses glass material to be about 10000 square centimeters (50cmx50cmx4 pieces).And an external diameter 5.8cm (diameter of inner pipe 4.7cm), the circular vacuum tube of long 200cm, daylighting area is that 940 square centimeters (4.7cmx200cm) to use glass material be 6280 square centimeters (5cm＜compromise〉x3.14x200cmx2), if daylighting area reaches 2400 square centimeters, then circular vacuum tube uses glass material to be about 16034 square centimeters (2400 ÷ 940x6280), and the circular vacuum tube materials of obvious identical daylighting area just Duo 50% than the plate type solar vacuum collector; Same daylighting area is identical, long-pending 5000 square centimeters of plate type solar vacuum collector selective coating aspect, and circular vacuum tube is 7536 square centimeters (4.7cmx3.14x200x2400 ÷ 940), and circular vacuum tube dope layer area is greater than plate type solar vacuum collector dope layer 50%.

Heat collector of the present utility model is that the vacuum tube collector to present use improves, promptly circular vacuum tube is changed into planar square, increase a circulation interface, so just having solved circular vacuum tube can not blowdown, clean inconvenient, the difficult problem of length after heat service time decrease in efficiency. the utility model is installed more convenient, the thermal efficiency is higher, if the plate type solar vacuum collector of several unit is coupled together, both can make the large-sized solar collector uses, also can be placed in top of building, do solar water heater usefulness, also can doublely do thermal insulation layer and use. plate type solar vacuum collector cost has only 70%. of circular vacuum tube collector

The specific embodiment

As shown in Figure 1, 2, plate type solar vacuum collector of the present utility model is made of dielectric layer 6 (water or other high boiling liquid), extexine 8 and endosexine 7; Dielectric layer is an airtight cuboid or a square, each open cycle hole (medium circulation interface) 1,2 of upper and lower at this cuboid or square, the perforate internal diameter is not less than 15mm, extexine and endosexine are connected and fixed by support 4 and dielectric layer, scribble solar selectively dope layer 5 at dielectric layer outer surface (in the face of that face of sunlight), form vacuum layer 3 between dielectric layer and extexine and endosexine.

Several plate type solar vacuum collectors can be placed on the support at certain angle of inclination, using flexible pipe to be together in series up and down is one group (every group can connect polylith plate type solar vacuum collector), again every group is coupled together side by side and get final product, as shown in Figure 3, Figure 4; Another kind of connection method is to be connected in parallel, and all heat collectors are arranged in a row, and end interface connects together as the circulating box upper circular tube on all, and end interface connects together as circulation pipe under the circulating box under all, as shown in Figure 6.
