Description

Solar flat plate collector

Technical Field

The utility model relates to a solar water heater field, concretely relates to flat plate solar collector.

Background

The flat-plate solar heat collector is a device for absorbing solar radiation energy and transferring heat to a working medium, and is a special heat exchanger, and the working medium in the heat collector exchanges heat with remote sun. The flat-plate solar heat collector consists of a frame profile, a heat absorption plate core, a transparent cover plate, a heat insulation material and related parts.

In recent years, along with the policy of 'more than one hundred meters building is required to be forcibly reserved with solar installation positions' in many provinces such as Shandong, the demand of balcony wall hanging products is increased by 9 percent in 2017 on the same scale. Most of common flat plate collector products are installed in a side outlet mode, on one hand, the installation pipeline is easy to be bent at right angles in the installation process, so that the steam blockage phenomenon of product media during circulation occurs, and the heat exchange effect is not ideal; on the other hand, the exposed installation pipelines are exposed on the wall surface, and are disordered in the overall visual effect, so that certain influence is generated on the building integration and the attractiveness.

SUMMERY OF THE UTILITY MODEL

The to-be-solved problem of the utility model is to provide a solar flat plate collector, medium access connection and medium outlet connection are located flat plate collector's backplate department, reduce pipeline installation's quarter bend, and more perfect be applicable to the high-rise building installation.

The utility model discloses a realize through following technical scheme:

a solar flat plate collector comprises a profile frame, a back plate and a heat absorption metal flow channel pipe group, wherein two sides of the heat absorption metal flow channel pipe group are respectively communicated with a collecting pipe to form a medium sealing flow channel, the collecting pipe is provided with at least one medium inlet connector and a medium outlet connector, the medium inlet connector and the medium outlet connector are fixed on the inner side surface of the back plate through pipe orifice clamping pieces, and the back plate is provided with a mounting hole capable of communicating the medium inlet connector and the medium outlet connector from the outside.

Furthermore, the medium inlet joint and the medium outlet joint are bent pipes, and the bending angle is an obtuse angle; the pipe orifice clamping piece is a galvanized plate piece which is distributed in an inclined mode.

Furthermore, the number of the medium inlet joints and the medium outlet joints is 2-4.

Compared with the prior art, the utility model the beneficial effect who gains as follows:

1. the medium inlet joint and the medium outlet joint are positioned at the back plate of the flat plate collector, so that the traditional design of discharging pipes from the side surface is avoided, the flat plate collector is more perfectly suitable for high-rise building installation, and the attractiveness is improved;

2. the medium inlet joint and the medium outlet joint are fixed on the inner side surface of the back plate through the pipe orifice clamping piece, so that the joints are prevented from extending out of the back plate, the influence on an automatic production line of a product is avoided, and the productivity and the efficiency are not influenced;

3. the medium inlet joint and the medium outlet joint are bent pipes, and the bent angle is an obtuse angle, so that the right-angled bend in a medium flowing path can be avoided after the medium inlet joint and the medium outlet joint are installed, and normal heat exchange can be realized;

4. the utility model discloses with the advantage of building perfect combination, there is not the outer pipeline that leaks in building outward appearance, it is more pleasing to the eye.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings. The described embodiments are only some embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.

A solar flat plate collector, section bar frame 1, backplate 2, heat absorption metal runner nest of tubes, reflection of light aluminum plate, glass apron and heat preservation cotton layer 3. The heat absorption metal runner pipe is formed by welding heat absorption plates in a curling mode or a heat absorption coating is plated on the surface of the metal pipe, the two sides of the heat absorption metal runner pipe are connected to the collecting pipe through the metal pipe to form a medium sealing runner, and the surface heat absorption coating has high absorption ratio and low emission ratio and plays a role in absorbing sunlight, converting the sunlight into heat energy and transferring the heat energy to a medium in the runner. Reflection of light aluminum plate is located the lower part of heat absorption metal runner nest of tubes, and on the four sides was fixed in section bar frame 1, reflection of light aluminum plate was plate or circular arc type, and the surface had the reflection coating, will have high reflectance, can effectively collect the sunlight, makes heat absorption metal runner nest of tubes do not have the dead angle and accepts the illumination, improves heat absorption efficiency. The back plate 2 plays a role in sealing, is positioned at the bottom of the heat collector and is fixed through the section bar frame 1. The section bar frame 1 plays a role in fixing and is positioned on four edges of the solar heat collector.
