BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rectangular solar collector frame structure having a bent-type sealing structure, more specifically, a frame of a flat panel solar collector has a rectangular shape, and four frames are welded together, The sealing of the joint portion is incomplete, so that moisture and foreign substances penetrate from the outside, adversely affecting performance and durability of the collector. To prevent such moisture and foreign matter from penetrating, one long frame is used to bend four corners It is possible to prevent penetration of moisture and foreign matter through the frame by processing only one cut part and to prevent the penetration of the permeable body fixing part at the upper part of the collector and the rear plate fixing part at the lower part of the collector, Assembled with the structure of the fitting method, and the moisture and foreign matter from the upper and lower parts of the collector To a rectangular solar collector frame structure having a bent-type sealing structure for preventing penetration and stably maintaining the performance of the collector for a long period of time.

A solar collector is a device that collects energy from the sun and converts it into heat. It is usually transparent glass or plastic plate that transmits sunlight, converts heat from copper or aluminum heat plate inside the glass to heat, and heat-exchanges it with heat storage medium It is a device used for heating or hot water.

These collectors using solar heat are largely divided into flat plate type and vacuum tube type.

The flat plate type solar collector has a rectangular flat plate shape. The flat plate type solar collector is formed of a thin plate made of copper or aluminum or the like, and has a surface treated with special chemical treatment so as to absorb the sun rays to the maximum. A plurality of thin branch pipes made of a common copper material that receives heat from a plurality of thin branch pipes are arranged at regular intervals and then welded and inserted into a rectangular frame and a transparent lid is formed thereon to form an integral collector, Insulation to prevent heat loss is placed, and the outside of the side and bottom is made of metal or a frame made of non-ferrous metal or plastic.

The working principle is that the solar heat heats the heat collecting plate and the heated heat collecting plate transfers the heat energy to the heat medium such as water in the branch tube and the heat medium which is heat exchanged in the tube is joined at the main pipe of the heat collector Thereby providing heat energy.

In this case, the flat plate type solar collector may be used by directly heating water, but in an area where the winter season and the cold season exist, an antifreeze is used as a heating medium rather than water.

In addition, the vacuum tube type solar collector has a glass tube shape and is formed to vacuum heat a closed space in contact with the solar heat collecting surface to block heat loss due to convection. The structure is divided into a method of using one glass tube and a method of a double tube type using two glass tubes.

In the method of using a single glass tube, a heat collecting plate having a heat pipe is inserted into a glass tube, a heat pipe is protruded to the upper end of the glass tube, the tube is sealed with a metal stopper, Thereby preventing solar heat collected from the surface of the heat collecting plate from being lost to the outside by convection.

In addition, in the method of using two glass tubes in the form of a double tube, a double tube is formed by vacuum processing the space between the outer tube and the heat-collecting tube specially treated for solar heat collection, and the heat medium circulates inside the heat- It is a method to fill the U-shaped copper tube or water and to seal the upper part of the tube with an insulating cap so as to warm the water filled inside the tube. At this time, the space between the outer tube and the heat-collecting tube is cut off heat loss due to convection of air due to vacuum treatment.

Among the above-described solar heat collectors, flat panel type solar collectors are the most popular type because of their low production cost and excellent durability. However, since the frame structure of the flat panel type collector is rectangular, four frames are bonded by using welding, rivets, screws or the like, so that moisture and foreign substances penetrate into the inside of the heat collecting plate through the bonding portion. Thus, the heat collecting performance is lowered and the durability There is a problem of deterioration.

6 is an exemplary view showing a frame structure of a conventional flat plate type solar collector. Generally, the solar collector keeps its high performance at the beginning, but since foreign substances and moisture are introduced from the outside through the four corners of the collector frame, the permeable body of the collector and the rear panel of the collector after the lapse of time, The thermal efficiency of the collectors is lowered and the heat collecting plates are corroded to shorten the life span. In particular, there is a problem in that the moisture is introduced through the coupling portion of the collector frame edge and the upper portion of the collector of the collector, and the moisture seriously inhibits the transmission of sunlight and corrodes the heat collecting plate, thereby reducing the economical efficiency of the collector.
