Long frame for solar assembly

Abstract

The invention discloses a long frame for a solar assembly. The long frame comprises a frame body and a pressing strip connected with the frame body in a clamped manner; the pressing strip comprises a hook-shaped vertical edge and a transverse edge; the frame body comprises a vertical frame, a first transverse frame, a second transverse frame and a third transverse frame; the first transverse frame is provided with an inversed-L-shaped bayonet; the upper portions of the first transverse frame and the third transverse frame are each provided with an arc-shaped groove and cylindrical glass cement which are the same in diameter, and a rectangular through hole is formed in the middle portion of the vertical frame; the two portions, at the two sides of the rectangular through hole, of the vertical frame are each provided with at least one reinforcing rib, and a closed type insertion hole is formed in the upper end of the vertical frame; and a limiting protruding strip slanting downwards is further arranged at the movable end of the transverse edge. The long frame is good in sealing effect, damage caused by heat expansion and cold contraction can be effectively prevented, adjacent solar assemblies can be fixed from the middle portion of the frame, and dislocation is not prone to happening to the long frame.

Description

technical field [0001] The invention relates to the technical field of solar energy equipment, in particular to a long frame for a solar module. Background technique [0002] After decades of development, flat-panel solar collectors have become more mature and perfect in technology, and have advantages that other types of solar energy do not have. Flat-plate solar collectors have good pressure-bearing performance and high thermal efficiency, and are especially suitable for integration with buildings. Due to its planar structure characteristics, in the application of building integration of solar energy, the flat plate solar collector has a flexible and random shape and structure, and the design is not restricted by shape or size, and it is easy to realize the combination with building components. In addition, its heat collecting plate is made of metal, which can be easily connected by wire knot and welding, which provides convenience for installation, maintenance and use. ...

AI Technical Summary

Problems solved by technology

Due to the unreasonable design of the frame of the existing solar heat collector, the structure of the sealing strip used for sealing is complicated, the sealant is easy to fall off, the sealing material is wasted and the sealing effect is very poor, water leakage is easy to occur, and its service life is shortened ; In addition, the existing solar collectors are usually arranged in series, using a common working fluid pipeline between adjacent solar collectors, only relying on the support frame of the solar collectors to keep them parallel to each other, so that the working fluid It is difficult to connect the main pipes smoothly, and it is more cumbersome to set up a separate working medium main pipe for each solar collector, and it will increase the cost
