Specific embodiment

Illustrate below in conjunction with the accompanying drawings, the utility model is described in further detail.

As shown in Figure 1-2, a kind of flat plate collector, including side be evenly equipped with the absorber plate 1 of multiple first tube seats 11 and One-to-one corresponding is arranged at the heat-transfer pipe 2 in the first tube seat 11.Specifically, the first tube seat 11 is shaped in the one of absorber plate 1 Side, the cross section of the first tube seat 11 is semicircular structure, and mutually parallel between each first tube seat 11, each heat-transfer pipe 2 is equal One-to-one corresponding is positioned in the first tube seat 11.Additionally, heat transfer adhesive 4 can be filled between the tube seat 11 of heat-transfer pipe 2 and first, Thus, it is possible to eliminate the thermal resistance caused by the gap between absorber plate and heat-transfer pipe, heat transfer efficiency is improved.

Each first tube seat 11 is equipped with lock hot plate 3, and lock hot plate 3 covers at heat-transfer pipe 2.Lock hot plate 3 is by minute surface Reflective aluminium flake is made.Wherein, locking hot plate 3 includes the second tube seat 31 coordinated with the first tube seat 11 and is respectively arranged at second The linking part 32 of the both sides of tube seat 31, linking part 32 is connected to absorber plate 1, the cross section of the second tube seat 31 by laser welding mode For semicircular structure, the first tube seat 11 and the second tube seat 31 are cooperatively formed can be by the tight of heat-transfer pipe 2 Hough knot therein Structure.In the present embodiment, the second tube seat 31 and linking part 32 are integrally formed by the reflective aluminium flake of minute surface and are made, wherein, minute surface is reflective Aluminium flake has high infrared reflection rate, is prevented from the heat in heat-transfer pipe in the form of electromagnetic infrared wave to emission, improves Heat insulation function.

In addition, it can include framework 5, absorber plate 1 is arranged in framework 5.Framework 5 includes frame 51, backboard 52 and glass Glass cover plate 53, the edge of frame 51 is integrally formed with the bottom margin of backboard 52 and is connected, thereby it is ensured that being formed in framework 5 Sealing space, solves the problems, such as gas leakage and caused collection heating rate is low and heat insulation effect is poor.Glass cover-plate 53 is covered on frame 51, tool The edge of glass cover-plate 53 can pass through sealing joint strip or fluid sealant couples the top of frame 51 for body, to ensure The inside of framework 5 is airtight.

In addition, it can include the first heat-insulation layer 61 and the second heat-insulation layer 62, the bottom side of the first heat-insulation layer 61 can be pasted Conjunction is arranged at backboard 52 towards the side inside framework 5；The laminating of second heat-insulation layer 62 is arranged at the medial surface of frame 51, thus, can To be incubated to the space in framework 5, heat waste is reduced.Absorber plate 1 is provided with the one side of heat-transfer pipe 2 and can be fixedly installed on The top side face of first heat-insulation layer 61, additionally, the first heat-insulation layer 61 integrally formed with correspond for be installed with heat-transfer pipe 2 multiple the Three tube seats 63, that is to say, that the second tube seat 31 can be just positioned on the 3rd tube seat 63 so that the first heat-insulation layer 61 Setting is brought into close contact with absorber plate 1, thus, it is to avoid gap is produced between the heat-insulation layer 61 of absorber plate 1 and first, increases heat insulating ability Can, reduce heat waste.

Wherein, the first heat-insulation layer 61 and the second heat-insulation layer 62 are foaming-formed by polyurethane, polyurethane have light weight, Thermal conductivity factor is low, heat-resist, ageing-resistant, characteristic that is easily cohering with other base materials, thus, it is possible to improve the guarantor in framework 5 Temp effect.

Additionally, specifically, valve can be installed in the side of frame 51 filled with inert gas in framework 5, can First will be vacuumized in framework 5 by valve, then by valve to filling with inert gas in framework 5.Thereby, it is possible to prevent absorber plate Convection current heat waste is produced between 1 and glass cover-plate 53.

In sum, the utility model improves collecting efficiency by increase absorber plate and the contact area of heat-transfer pipe.

The above is only a kind of embodiment of the present utility model, it is noted that for those of ordinary skill in the art For, on the premise of design is created without departing from the utility model, some similar deformations and improvement can also be made, these Should be regarded as within protection domain of the present utility model.
