Description

Heat collector breathing hole structure

technical field

The utility model relates to a breathing hole structure of a heat collector.

Background technique

The flat-plate collector is exposed to sunlight for a long time, and the internal components are mainly the evaporation of water in the insulation layer. Water mist is prone to appear on the glass cover of the flat-plate collector, which affects the appearance and heat absorption efficiency. Therefore, it is necessary to punch holes (that is, breathing holes) between the glass cover plate of the heat collector and the heat-absorbing layer to increase air flow and discharge water vapor in time.

In the prior art, air flow and waterproofing inside the collector are realized by adding tubular breathing parts on the profile of the collector or the back plate of the collector, but the process is complicated and the cost is high.

On the whole, there are several problems in the breathing hole structure of split solar flat panel collectors on the market: first, the breathing hole of the collector is at the bottom of the insulation layer, which cannot achieve good circulation of air inside the collector. There is a problem of water mist on the cover plate; second, the breathing hole of the collector is not rainproof, and it is easy for rainwater to enter; third, the collector is equipped with breathing parts, which wastes materials and affects the appearance.

Installing additional tubular breathing parts on the collector is not only unsightly, but also complicated in process and high in material and labor costs, which is not conducive to industrialized mass production. The biggest problem is that the waterproof effect of the breathing holes is not good, and it cannot be solved. The problem of water mist on the glass cover of the collector also allows rainwater from the outside to enter, making the problem even more serious.

Utility model content

In view of this, the utility model focuses on solving three problems:

①The collector does not need to install any additional breathing parts, reducing material costs.

②The special structure of the breathing hole of the collector can effectively prevent the outside rainwater from entering.

③The air circulation inside the collector is good, which solves the problem of water mist inside the collector.

The purpose of the utility model is to provide a breathing hole structure of the heat collector, which solves the problems of air circulation inside the heat collector and the waterproofing of the breathing hole through the special breathing hole structure of the profile parts without additional breathing parts.

The utility model provides a heat collector breathing hole structure, wherein a groove structure is arranged on a four-corner connector connecting the heat collector frame, and the breathing hole is arranged inside the groove structure to connect the inside and outside of the heat collector.

The heat collector has a new type of breathing hole structure. By adding a hole structure to the structure of the heat collector profile itself, the breathing hole can achieve the purpose of good air circulation inside the heat collector and solve the problem of water mist in the flat solar market. The new structure does not need to install additional heat collector breathing parts, has low cost, simple structure, reliable rainproof structure, and is suitable for industrialization and mass production requirements.

Preferably, the breathing hole is arranged between the collector glass and the collector plate core.

Here is the main existence area of air, the air fluidity is good, and there will be no water mist in the collector.

Preferably the breathing opening is covered from above by a gland.

This makes it impossible to see the breathing hole from the appearance, which is beautiful and practical.

Preferably, on the outside of the four-corner connector, a rainproof ring is arranged around the breathing hole.

Adding a rainproof ring around the breathing hole on the outside of the four-corner connector can prevent water from entering the interior of the collector.

Preferably, the rainproof ring is a circular tubular structure.

The circular structure is simple and has high strength.

Detailed ways

As shown in FIG. 1 , the four-corner connector 1 is composed of two side plates and a bottom plate, the three are perpendicular to each other, and a groove structure 3 is arranged on one side plate of the four-corner connector 1 . The groove structure 3 is a structure recessed downward from the inner wall of the side plate, and the recess shown in FIG. 1 is square. A breathing hole 2 is formed inside the groove structure 3 . In this embodiment, the breathing hole 2 is circular, and two are formed side by side. Breathing holes 2 are used to connect the inside and outside of the heat collector.

In FIG. 2 , after the four-corner connector 1 is covered with a gland 4 , the breathing hole 2 is hidden from above by the gland 4 . From the appearance, there is no breathing hole, beautiful and practical.

Because the breathing hole 2 is arranged in the groove structure 3, the breathing hole has enough space and will not be blocked by the gland.

The breathing hole 2 is added between the glass of the heat collector and the plate core of the heat collector, where the air mainly exists, the air flow is good, and the water mist of the heat collector does not appear.

As shown in FIG. 3 , a rainproof ring 5 is arranged outside the breathing hole 2 . In this embodiment, the rainproof ring 5 blocks the breathing hole 2 inside through a circular tubular structure, so that external rainwater and the like will not enter the interior of the heat collector through the breathing hole 2 . The collector is generally placed at an angle of 45 degrees to the south, and the rainwater showers, and the rainproof effect is very good.

In this embodiment, by adopting a structure for the breathing hole of the heat collector, good circulation of the air inside the heat collector can be ensured. No additional collector breathing parts are added, and there are few parts. The appearance is beautiful, and the rainproof structure is reliable.

The structures described in the above embodiments do not limit the scope of the claims of the present utility model, and the present utility model can be modified arbitrarily within the scope of its technical ideas. For example, the concave structure inside the breathing hole of the heat collector can also be a circular depression, a polygonal depression, etc., and the breathing hole can be polygonal or other shapes. The outer rainproof ring of the collector breathing hole can be circular, square, polygonal, and the length can be flexible and changeable.
