technical field

The utility model belongs to a solar heat collecting plate, in particular to a serpentine double-layer channel solar air heat collecting plate which can effectively utilize solar energy to heat air.

Background technique

At present, most of the technical patents related to "solar heat collecting panels" disclosed in Chinese patents are solar heat collecting panels using water as the heating medium. Its basic structure is composed of frame, glass plate, heat collecting plate and heat insulating plate. The heat absorbing coating is coated on the light receiving surface of the heat collecting plate. The water outlet is provided with water flow grooves on the heat collecting plate. The structure is simple and the cost is low. However, there are many situations in which hot air is required to perform related work tasks. Use solar energy to heat the air to complete various tasks such as drying of agricultural products, room heating, and facility agricultural security. It requires less investment, saves energy, and is easy to use. Therefore developing the solar air heat collector is a problem to be solved urgently.

Contents of the invention

The purpose of the utility model is to provide a serpentine double-layer channel solar air heat collector, which has simple structure, large heat exchange area, high heat exchange efficiency, light weight, low price and convenient use.

The purpose of the present invention is achieved in this way: a serpentine double-layer channel solar air heat collector, including a box body composed of a thermal insulation board arranged on the bottom plate of the frame and a light-transmitting plate installed on the top surface of the frame, and installed in the box Next to the heat collecting plate, the air inlet pipe and the air outlet pipe are arranged on the box body, and the heat collecting plate is arranged in parallel between the heat preservation plate and the light-transmitting plate, which divides the box body into a preheating chamber and a heating chamber. In the chamber and the heating chamber, partitions parallel to each other are evenly distributed in the horizontal direction, and each adjacent two partitions are provided with openings that are staggered from the beginning to the end, so that the preheating chamber and the heating chamber respectively form a serpentine curved channel. The air inlet pipe communicates with one end of the preheating chamber, the ventilation hole provided on the heat collecting plate at the other end of the preheating chamber communicates with the heating chamber, and the air outlet provided on the heat collecting plate at the other end of the heating chamber communicates with the air outlet pipe.

The utility model absorbs solar energy by the solar air heat collecting plate, and directly heats the air, so that the air gets a higher temperature to complete the follow-up work. When the utility model is working, the cold air enters the preheating chamber from the air inlet pipe. Because the specific heat of the heat collecting plate is small, the temperature rises quickly after being heated. Long stroke, have sufficient heat exchange time with the heat collecting plate heated by solar energy, then enter the heating chamber through the ventilation hole, run in the serpentine curved channel formed by the partition plate in the heating chamber, and fully conduct heat with the heat collecting plate Exchange, the final outlet is drawn by the fan to heat the air into the working link to complete the corresponding work. Because the flow of cold air entering the utility model is long and the heat exchange area with the heat collecting plate is large, the air can have sufficient heating time, so that the effect of air heating is good, the heating temperature is high, and the heat conversion efficiency of sunlight is improved. The utility model has the advantages of simple and reasonable structure, high heat exchange efficiency, light weight, low price, convenient use and wide application range, such as drying of agricultural products, including vegetables, fruits, meat, grains, etc., as well as rural living rooms, public facilities and poultry. House, greenhouse temperature regulation.

Detailed ways

A serpentine double-layer channel solar air heat collector, as shown in Figure 1, Figure 2, Figure 3, and Figure 4, includes a light-transmitting plate installed on the bottom plate 4 of the frame 1 and a light-transmitting plate installed on the top surface of the frame 1. The box body that plate 9 forms, heat collecting plate 7 is installed in the box body, and air inlet pipe 2 and air outlet pipe 3 are arranged on the box body. The bottom plate 4 is made of plywood or fibreboard. Insulation board 5 is made of foamed benzene board. The light-transmitting plate 9 is made of a PC hollow solar panel or a glass plate. PC hollow solar panel has good light transmission effect, good heat insulation effect, light weight and low price. A heat collecting plate 7 is arranged in parallel between the insulating plate 5 and the light-transmitting plate 9, and the box body is divided into a preheating chamber 8 and a heating chamber 10. The support is fixed. In the preheating chamber 8 and the heating chamber 9, mutually parallel baffles 6 are evenly distributed transversely, wherein each adjacent two baffles 6 are provided with openings which are staggered from head to tail, so that the preheating chamber 8 and the heating The chambers 10 respectively form serpentine curved passages, the air inlet pipe 3 communicates with one end of the preheating chamber 8, and the ventilation holes 12 provided on the heat collecting plate 7 at the other end of the preheating chamber 8 communicate with the heating chamber 10, and the ventilation holes 12 are uniformly distributed. The via area constitutes. The air outlet hole provided on the heat collecting plate 7 at the other end of the heating chamber 10 communicates with the air outlet pipe 2 . The heat collecting plate 7 is made of an aluminum plate, and uniformly distributed embossed patterns are arranged on the surface of the aluminum plate. When the air flows over the evenly distributed embossed surface of the aluminum plate, a vortex is generated, which can increase the heat exchange between the heating plate and the air, reduce sunlight reflection, and improve the heat conversion efficiency of sunlight. Adhere to the black lacquer coating on the plate surface of heat collecting plate 9, can improve the absorption capacity of solar energy. The partitions 6 constituting the serpentine channel are all made of aluminum plates. The aluminum partition has the function of absorbing solar energy, and can also heat the air passing through, improving the heat exchange efficiency and air temperature.
