Abstract

An air-water compound solar energy heat collector is mainly formed by a glass cover plate (1), a plate core (2), a flow guide sheet (3), a margin frame (4), a heat preservation (5), a back plate (6), an air inlet square pipe (7) and an air outlet square pipe (8). The air-water compound solar energy heat collector not only can heat air media, but also can heat water media, and each medium can run independently and also in compound manner. The working process of the air-water compound solar energy heat collector includes that solar light illuminates on the plate core (2) by penetrating through the glass cover plate (1), and a solar energy selective coating layer on the surface of the plate core (1) absorbs the solar light to lead the temperature of the plate core (1) to rise and takes energy away by rapid flowing of air or water. The air-water compound solar energy heat collector is simple in structure and manufacturing process, convenient in connection and low in manufacturing and installing costs, and can be integrally used in large-scale manner.

Description

Air-Water Composite Solar Collector

technical field

The utility model belongs to the field of renewable energy development and utilization, and in particular relates to an air-water composite solar heat collector which can be applied to two media of air and water at the same time.

Background technique

At present, in the existing solar heat utilization technology, most solar collectors use water or air as a single medium to transfer energy, and the scope of application is relatively limited, and it cannot be widely promoted. Based on this, we have developed an air-water composite solar collector, which can heat both the air medium and the water medium, and each medium can operate independently and in combination, so that the solar collector can be widely used It is used in heating of buildings, drying of agricultural and sideline products, etc., and it is very necessary to design an air-water composite solar collector that meets the above technical requirements.

Contents of the invention

According to the background technology, the purpose of this utility model is to avoid the above-mentioned disadvantages, and to provide a tempered glass cover plate, a collector plate core, an aluminum alloy protective frame, a back plate, a back plate heat preservation, an air intake square pipe and an air outlet square Composed of tubes, it can be widely used in air-water composite solar collectors in the fields of building heating, drying of agricultural and sideline products, etc.

In order to achieve the above object, the utility model is achieved through the following technical solutions:

An air-water composite solar heat collector is mainly composed of a glass cover plate 1, a plate core 2, a guide plate 3, a frame 4, heat preservation 5, a back plate 6, an air intake square tube 7 and an air outlet square tube 8. The glass cover plate 1 is fixed on the frame 4. The glass cover plate 1 has good light transmission, and the sunlight can pass through the glass cover plate 1 and shine on the core 2. The solar selective coating is sprayed on the core 2, and the core 2 is fixed on the In the middle of the frame 4, there is a deflector 3 below. The deflector 3 can effectively control the flow rate and flow of the air. The heat preservation 5 and the back plate 6 are arranged under the deflector 3. The back plate 6 has an air intake square pipe on the upper and lower sides. 7 and air outlet square pipe 8. Its working process is that sunlight shines on the core 2 through the glass cover 1, and the solar selective coating on the surface of the core 1 absorbs sunlight to increase the temperature of the core 1, and the energy is taken away by the rapid flow of air or water . The utility model has the advantages of simple structure and manufacturing process, convenient connection, low manufacturing and installation cost, and large-scale integrated use.

Due to the above-mentioned technical scheme, the utility model has the following advantages and effects:

1. The utility model can heat two media, air and water, and can be integrated and used on a large scale, with a wide range of applications.

2. The utility model has simple structure and manufacturing process, convenient connection, low manufacturing and installation cost, and is economical and applicable.

3. The utility model adopts the setting of the deflector, and is applicable to heating two kinds of media at the same time, and the thermal efficiency is as high as 70%.

4. The glass cover, core and frame of the utility model are easy to disassemble, easy to clean and maintain.

5. The utility model adopts traditional building materials, which is not easy to be damaged and has high safety performance.

Detailed ways

As shown in Fig. 1, Fig. 2 and Fig. 3, an air-water composite solar heat collector is mainly composed of a glass cover plate 1, a plate core 2, a deflector plate 3, a frame 4, heat preservation 5, a back plate 6, and Gas square pipe 7 and air outlet square pipe 8 form. The glass cover plate 1 is fixed on the frame 4. The glass cover plate 1 has good light transmission, and the sunlight can pass through the glass cover plate 1 and shine on the core 2. The solar selective coating is sprayed on the core 2, and the core 2 is fixed on the In the middle of the frame 4, there is a deflector 3 below. The deflector 3 can effectively control the flow rate and flow of the air. The heat preservation 5 and the back plate 6 are arranged under the deflector 3. The back plate 6 has an air intake square pipe on the upper and lower sides. 7 and air outlet square pipe 8.

Its working process is that sunlight shines on the core 2 through the glass cover 1, and the solar selective coating on the surface of the core 1 absorbs sunlight to increase the temperature of the core 1, and the energy is taken away by the rapid flow of air or water .
