Description

A new type of flat solar collector frame

Technical field:

The utility model relates to the technical field of flat solar heat collectors, in particular to a novel outer frame of a flat solar heat collector.

Background technique:

With the development of society and the continuous consumption and exhaustion of global resources, countries around the world, including China, are advocating an environmentally friendly and energy-saving social development model, and the basic point of taking this path is to eliminate the traditional development model. pollution, and the use of new environmentally friendly and non-polluting energy to replace traditional energy in order to take a sustainable development path. Also under the guidance of these ideas, more and more countries are paying attention to the utilization of solar energy, and flat-panel solar collectors, as a model of utilizing solar energy, are being used in more and more occasions and fields. Generally, because the collector is installed outdoors, it is directly subjected to wind, rain, sun exposure, and natural environmental factors such as cold and heat for a long time. It is also occasionally attacked by hail and artificially thrown sundries. The conditions of use are very harsh. Among them, the requirements for the frame of the solar collector are getting higher and higher. It not only needs to have good sealing performance, but also requires its installation to be convenient. At the same time, its overall aesthetic performance and its production cost are also required by many related manufacturers. Considered and compelled to solve problems. However, the outer frames of flat solar collectors on the market currently have such problems: because they are fixed by rivets when clamping and fixing the backboard, this not only affects the overall aesthetics of the collector, but also Due to the way of rivet connection, it is also easy to deform the back plate, so that the air can easily enter the inside of the collector and generate convection in it. In addition, due to the weather, a certain amount of water will be formed in it, etc. The thermal efficiency of the system is low, and the components inside the collector are easily corroded, which shortens its service life and virtually increases its use cost.

Utility model content:

The purpose of this utility model is to provide a new type of flat solar collector outer frame by improving the existing technology in view of the above problems.

In order to achieve the above purpose, the utility model adopts the following technical solutions: a new type of flat solar collector outer frame, which includes a cover plate clamping part arranged on the upper end of the outer frame and cooperating with the bead, and a back plate arranged on the lower end of the outer frame The clamping part, wherein the back plate clamping part located at the lower end of the outer frame has a double-layer opening structure and its opening faces inward; wherein two convex ribs integrally formed with it are provided on the downward facing surface of the upper layer, Two grooves cooperating with the ribs are arranged on the upward side of the lower layer.

The beneficial effects of the utility model are: adopting the cover plate clamping part arranged on the upper end of the outer frame and cooperating with the bead, and the back plate clamping part arranged on the lower end of the outer frame, the back plate clamping part has a double-layer opening structure and Its opening faces inward; wherein, two convex ribs formed integrally with it are provided on the downward facing surface of the upper layer, and two grooves cooperating with the convex ribs are arranged on the upward facing surface of the lower layer. The outer frame of such a flat solar collector not only has good sealing performance, but also can better prevent the infiltration of airflow and rainwater; its overall appearance is more concise and beautiful, the manufacturing cost is lower, and the installation is more convenient. It improves the service life and cost performance of the collector.

Description of drawings:

Below in conjunction with accompanying drawing, the utility model is further described:

Fig. 1 is a partial sectional view of the utility model in use state.

Detailed ways:

See accompanying drawing 1, a kind of outer frame of new-style flat-plate solar heat collector, it comprises the cover clamping part 1 that is arranged on the upper end of the outer frame and cooperates with the bead, and the back plate clamping part 2 that is arranged on the lower end of the outer frame, wherein The above-mentioned back plate clamping part 2 located at the lower end of the outer frame has a double-layer opening structure and its opening faces inward; wherein, two convex ribs 31 integrally formed with it are provided on the downward side of the upper layer 3, and the lower layer 4, the upward facing side is provided with two grooves 41 that cooperate with the ribs 31. When using the outer frame to clamp the back plate 5, it is only necessary to insert the back plate 5 into the outer frame back plate for clamping. Part 2 then presses down the upper layer 3 of the backplane clamping part to make it press against the backplane 5 and form a good seal, and at the same time, the lower layer 4 of the backplane clamping part is also pressed against the backplane 5, and the backplane clamps Both the ribs 31 and the grooves 41 on the holding part 2 are beneficial to form a frictional force with the backboard and the sealing conditions are better, because the mutual cooperation between the upper and lower layers of the backboard clamping part 2 will not cause the backplane Deformation, getting rid of various disadvantages caused by the traditional use of rivets, better preventing the infiltration of airflow and rainwater, effectively improving the thermal efficiency of the system; at the same time, it also makes the overall appearance of the assembled flat plate collector more concise and beautiful. The manufacturing cost is lower, the installation is more convenient, and at the same time, the service life and cost performance of the heat collector are greatly improved.

Of course, the above-described embodiments are only preferred examples of the present utility model, and are not intended to limit the scope of implementation of the present utility model, so all equivalents done according to the structure, features and principles described in the scope of patent application for the present utility model Changes or modifications should be included in the patent scope of the utility model.
