Description

Reinforced aluminum frame for solar modules

technical field

The utility model relates to a reinforced aluminum frame of a solar module, which is mainly used for the installation of laminated parts of the solar module.

Background technique

At present, conventional solar modules are composed of solar module laminates and aluminum frames. Conventional solar module laminates, from top to bottom, are: tempered glass, EVA film, solar cells, EVA film, TPT back The film is made into a laminate through a lamination process, and then an aluminum alloy frame is installed around the laminate to make it a solar module. The frame for installing solar module laminates usually adopts an aluminum profile frame. The existing aluminum profile frame can be shown in Figure 1 and Figure 5. Usually, the solar cell module is installed in the installation groove 7 of the main frame, so that the solar module The laminate is only secured around all four sides. Since the thickness of solar module laminates is about 5mm, and the size is about 2m×1m, the EVA film and TPT back film are soft materials, and the surface strength of the module mainly depends on the strength of the tempered glass. When handling solar module laminates, the glass will bend to a certain extent due to its own strength, which will cause the solar cells inside the laminate to be cracked or even broken, resulting in damage to the performance of the solar module. Currently, around the solar laminates The aluminum frame is installed to increase its ability to resist bending. Due to the large area of the laminate, the edge has enhanced bending resistance due to the effect of the aluminum frame, but the middle part is still prone to damage to the internal solar cells due to the bending of the glass. In order to increase its strength, it is necessary to increase the thickness of the frame, thus increasing the aluminum material and increasing the cost.

Utility model content

The technical problem to be solved by the utility model is to provide a reinforced aluminum frame for solar modules with high strength and low cost in order to solve the problem of low strength of the existing aluminum profile frame. On the basis of the conventional aluminum frame, a number of reinforcing plates connected to the frame are arranged to divide the larger solar laminate into smaller parts, and the bending resistance of the glass in the smaller area is enhanced, thereby solving the problem of glass Larger bending leads to the problem of cracks in the internal solar cells.

The technical solution adopted by the utility model to solve the technical problem is: a reinforced aluminum frame for solar modules, including a main body frame, several pairs of wedge blocks and several reinforcement plates, the main body frame includes an upper frame, a lower frame, a first The vertical frame and the second vertical frame are provided with installation grooves on the main frame, the two ends of the first vertical frame are respectively connected with the upper frame and one end of the lower frame, and the two ends of the second vertical frame are connected with the upper frame and the lower frame respectively. The other end of the lower frame is connected, and the wedge blocks are fixedly connected in pairs on the inner sides below the installation grooves of the first vertical frame and the second vertical frame, and the reinforcing plate is squeezed and fixed on the wedge-shaped block by equipment when the component frame is installed. on the block.

In order to ensure that the middle part of the aluminum frame will not easily cause damage to the internal solar cells due to the bending of the glass, a step is provided on the end surface of the reinforcing plate. After installation, the lower surface of the solar cell module laminate can fit the step, increasing the The supporting force avoids the damage to the solar cells caused by the cracks caused by the bending of the laminated glass.

In order to enhance the strength of the reinforcement board, reinforcement ribs are arranged transversely on the lower end surface of the reinforcement board.

In order to make the wedge-shaped block and the reinforcement plate fixedly connected, the wedge-shaped surface of the wedge-shaped block faces upwards and a number of barbs are arranged on the wedge-shaped surface, and the two ends of the reinforcement plate are respectively provided with downward-facing wedge-shaped surfaces and the wedge-shaped surface is provided with Barb one matches a number of barbs two.

In order to make it difficult to get loose between the wedge-shaped block and the reinforcing plate, the first barb and the second barb are arranged vertically upward along the wedge-shaped surface.

The beneficial effects of the utility model are: the reinforced aluminum frame of the solar module of the utility model adds a number of reinforcing plates between the first vertical frame and the second vertical frame. "口"-shaped frame combination is divided into several small "口" parts, and the end surface of the reinforcement board is in contact with the back of the solar module laminate, so that the laminate with a larger area is also divided into several small parts, which improves the performance of the module laminate. Compared with the traditional aluminum profile frame, the anti-bending ability of the glass effectively increases the overall support force. Under the premise of meeting the support requirements, the height of the side of the aluminum frame can be reduced, and the amount of aluminum material is reduced. At the same time, the reinforcing plate can be used according to It is necessary to use raw materials of other materials, which saves costs.
