Abstract

The utility model discloses a solar flat-plate collector with a buffer inside, which comprises a framework and a heat collecting plate core in the framework. A transparent panel and a heat-insulation plate are respectively arranged on two sides of the framework, and the expansion buffer which is communicated with the heat collecting plate core is arranged in the framework. Due to the structure, when heat absorbing media are expanded after absorbing heat, the heat absorbing media can be compressed into the expansion buffer, the expansion buffer has good buffering effect, so that the problem that weak portions of closed pipe networks are damaged to leak liquid due to expansion of the volume of the heat absorbing media can be prevented, the expansion buffer is arranged in the framework, and accordingly the space in the framework can be effectively utilized without affecting attractiveness of an indoor environment.

Description

Built-in buffer formula plate solar collector

Technical field

The utility model belongs to technical field of solar utilization technique, particularly a kind of built-in buffer formula plate solar collector.

Background technology

Solar energy is as a kind of clean energy resource, is again simultaneously a kind of inexhaustible, nexhaustible energy and being favored by countries in the world, now people utilize solar energy maximum be to obtain hot water.Flat plate collector is as modal a kind of heat collector in the middle of the solar water heater, the concrete structure and the operation principle of existing flat plate collector are: flat plate collector comprises by the medium inlet pipe of some canalis pterygoideus arrangement connections and medium going out to manage, medium inlet pipe and medium go out to manage the outer end and are connected and are deep in the water tank, canalis pterygoideus is provided with the fin that is used to absorb solar heat, scribble the sunlight heat absorber coatings above the fin, the liquid heat-absorbing medium is housed in the canalis pterygoideus, solar irradiation is mapped on the fin, fin conducts the heat that absorbs to canalis pterygoideus, canalis pterygoideus is with the heat transferred heat-absorbing medium, the heat-absorbing medium of high temperature goes out pipe by medium and enters in the water tank and by heat-exchanger rig the water in the water tank is heated, and flow back in the flat plate collector by the medium inlet pipe through heat conducting low temperature heat-absorbing medium again.The route that circulates that is heat-absorbing medium is: canalis pterygoideus → medium goes out the heat-exchanger rig → medium inlet pipe → canalis pterygoideus in the pipe → water tank.Because heat-absorbing medium is to circulate in airtight pipe network, under the too big situation of extraneous variations in temperature, heat-absorbing medium expands with heat and contract with cold, and also the phase strain is big for degree, and this just causes big pressure to airtight pipe network, and place weak in the tube chamber is burst and leakage.The manufacturer or the user that much are ignorant of this principle do not install expansion drum at all, and this just is easy to product is caused bigger harm, shorten the service life of product.Also there are a lot of flat plate collectors to go out to hang on the pipe expansion drum now at medium inlet pipe or medium, pressure when being used to cushion heat-absorbing medium heat and rising, for large flat heat collector such as engineering connection in series-parallel heat collector, expansion drum is installed not too to be influenced attractive in appearance, and for home-use flat plate collector, it is just very not attractive in appearance to hang an expansion drum in doors, is subjected to significant limitation in the stage of applying.

The utility model content

The utility model is in order to solve weak point of the prior art, provides a kind of and can stop the destruction that heat-absorbing medium heat expansion degree causes airtight pipe network when big and not influence indoor built-in buffer formula plate solar collector attractive in appearance.

For solving the problems of the technologies described above, the utility model adopts following technical scheme: built-in buffer formula plate solar collector, comprise the heat-collecting plate core in framework, the framework, the framework both sides are respectively equipped with transparent panel and thermal insulation thermal insulation board, and described framework inside is provided with the harmomegathus buffer that is communicated with heat-collecting plate core.

Described heat-collecting plate core comprises that the medium inlet pipe and the medium that be arranged in parallel go out pipe, medium inlet pipe and medium go out between the pipe by at least one canalis pterygoideus connection, canalis pterygoideus is provided with the fin that is parallel to transparent panel in contiguous transparent panel one side, flap surface is provided with the sunshine absorber coatings, and described harmomegathus buffer is communicated with the medium inlet pipe.

Adopt said structure, after absorbing heat, heat-absorbing medium expands, heat-absorbing medium may be compressed in the harmomegathus buffer, the harmomegathus buffer plays good cushioning effect, can prevent the heat-absorbing medium volumetric expansion like this and the weakness of airtight pipe network is damaged and leakage, the harmomegathus buffer is located in the framework, effectively utilizes in the framework locally, and does not influence indoor attractive in appearance.The utility model is reasonable in design, simple structure, lightly durable, cheap, both artistic and practical, be convenient to install, security is good, stopped the destruction that heat-absorbing medium heat expansion degree causes airtight pipe network when big effectively, be easy to apply, be not only applicable to numerous domestic consumers, be applicable to the large-scale hot water units that use such as large-scale dining room, bathing yet.

The specific embodiment

Embodiment one: as Fig. 1, Fig. 3 and shown in Figure 4, built-in buffer formula plate solar collector of the present utility model, comprise the heat-collecting plate core in framework 1, the framework 1, framework 1 both sides are respectively equipped with transparent panel 2 and thermal insulation thermal insulation board 3, and framework 1 inside is provided with the harmomegathus buffer 4 that is communicated with heat-collecting plate core.Heat-collecting plate core comprises that the medium inlet pipe 5 and the medium that be arranged in parallel go out pipe 6, medium inlet pipe 5 and medium go out between the pipe 6 by 7 connections of at least one canalis pterygoideus, canalis pterygoideus 7 is provided with the fin 8 that is parallel to transparent panel 2 in contiguous transparent panel 2 one sides, fin 8 surfaces are provided with the sunshine absorber coatings, and harmomegathus buffer 4 is communicated with medium inlet pipe 5.Harmomegathus buffer 4 is located in the framework 1, effectively utilizes in the framework 1 locally, and does not influence indoor attractive in appearancely, and display medium inlet pipe 5 and medium do not go out pipe 6 structures that heat-exchanger rig is communicated with in water tank among the figure.Present embodiment is applicable to the large-scale hot water unit that uses, and medium inlet pipe 5 and medium go out pipe 6 and be equipped with series-parallel interface at framework about 1.

When work is used, be one, be hung on the wall on the sunny side a plurality of the utility model serial or parallel connections.After absorbing heat, heat-absorbing medium 9 expands, air in the harmomegathus buffer 4 is compressed, part heat-absorbing medium 9 enters in the harmomegathus buffer 4, thereby reduce to go out the heat-exchanger rig in pipe 6, the water tank, the pressure that airtight pipe network bore that medium inlet pipe 5 is constituted by canalis pterygoideus 7, medium, even heat-absorbing medium 9 extreme expansion, harmomegathus buffer 4 also can play good cushioning effect, so just can prevent heat-absorbing medium 9 volumetric expansions and the weakness of airtight pipe network is damaged and leakage.

Embodiment two: as shown in Figures 2 and 3, be with embodiment one difference that medium inlet pipe 5 and medium go out the port shutoff of pipe 6 in framework 1, promptly only stay a connector, single use outside framework 1 respectively.This embodiment can be widely used in the domestic consumer.
