Due to the characteristics of the material of this type of heat collector and the inherent mode of design, there are many problems such as complex manufacturing process and inconvenient transportation in the specific manufacturing, transportation, installation, and use of this type of solar water heater and heat collector. . In addition, the integration of solar energy and buildings is currently a matter of great concern to both solar water heater manufacturers and architectural design units. However, the current plate and tube structures of solar collectors cause many problems in the integrated design of them and buildings. Therefore, no matter in terms of cost, installation, or integration with buildings, designing a good solar collector has always been a matter of great concern to many manufacturers of solar water heaters and collectors.

Contents of the invention

The purpose of the present invention is to overcome many shortcomings of existing solar heat collectors, and provide a blanket type solar heat collector with low cost, simple processing and manufacturing, and easy transportation, installation and disassembly. Especially suitable for solar water heater collectors for medium and low temperature hot water.

In order to realize the above-mentioned purpose of the invention, the technical scheme adopted is as follows:

A blanket-type solar heat collector, comprising a water diversion device and a heat collector body, the heat collector body includes a heat collection blanket and a hollow water flow channel arranged on the heat collection blanket, the water diversion device is hollow and has one end A cylinder with a first opening, and a second opening connected to a hollow water channel on one side of the cylinder, and the main body of the heat collector is made of flexible or elastic material.

In the above technical solution, the heat collecting blanket is made of photothermal elastic plastic.

The hollow water channel is made of plastic tubes. The material is the same photothermal elastic plastic as the heat collecting blanket.

The heat-collecting blanket adopts a square structure, and the heat-collecting blanket is embedded with a plurality of hollow water channels formed by a plurality of plastic tubes. The second opening of the water device is connected.

The plastic pipe is connected with the second opening through socket or glue.

The main body of the heat collector is an integrally formed structure, which is formed at one time by extrusion or molding.

The main body of the heat collector of the present invention is made of elastic plastic material with light-to-heat conversion effect. The heat collector has the characteristics of being rollable, bendable, and foldable. It can be laid flat on the roof or hung on the wall during installation without additional brackets. Or a frame device, which can well realize the integration of solar energy and buildings.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings.

The overall structure of the present invention is shown in accompanying drawing 3, is made up of heat-collecting blanket main part and sub-water collection device. Wherein the sub-water collection device is located at both ends of the heat collecting blanket main body, and is connected with a plastic pipe protruding from the hollow water channel of the heat collecting blanket main body through a socket connection.

The structure of the heat collecting blanket body is shown in Figures 1 and 2, including the hollow water flow channel 1 and the heat collecting blanket 2. The hollow water flow channel 1 and the heat collecting blanket 2 adopt an integrated design and are formed by extrusion or molding at one time. The material selection Photothermal elastic plastic. The structure of the main body of the heat collecting blanket is a square blanket, the outer surface is a heat collecting blanket 2, and a hollow water flow channel 1 is embedded in it. The part of the plastic pipe protruding from the embedded hollow water channel 1 is connected to the water diversion device 3 on both sides through socket or glue.

The structure of the sub-water collecting device 3 is as shown in accompanying drawing 3, the sub-water collecting device 3 is hollow and one end is provided with a column 31 with a first opening 32, and one side of the column 31 is also provided with a connection with the hollow water channel 1. the second opening 33 .

The main body of the heat collecting blanket of the present invention has a thickness of 25 mm, a shape of a rectangle with a length of 1.5 m and a width of 0.42 m, wherein the hollow water channel 1 has ten channels in total, and the inner and outer diameters of the protruding parts are respectively 18 mm and 20 mm, and the distance between the two channels is 20mm, and the length of the part of the hollow water channel 1 protruding from the thermal blanket 2 is 50mm.

The application process of the present invention is as follows:

Lay the blanket-type solar collector on the roof or hang it on the wall, fix it, and the water flow flows into the hollow water channel 1 in the heat-collecting blanket 2 with light-to-heat conversion effect through the water diversion device 3, and then passes through the solar energy collector. The heated water flows out through the water diversion device 3 again, completing the whole process of solar energy heating water.

The length, width and thickness of the main part of the heat collecting blanket of the present invention can be adjusted, the hollow water flow channel 1 can be round or square, oval or other shapes, and the hollow water flow channel 1 can be completely embedded in the heat collecting blanket 2 . And the number of hollow water channels 1 of each blanket type can also be adjusted accordingly.
