Description

Technical Field

[0001] This utility model belongs to the technical field of solar hot air generating equipment, and particularly relates to a solar thermal collector. Background Technology

[0002] Solar air heating equipment is a device that uses solar radiation to heat air. Hot air has many uses, such as heating and drying agricultural and sideline products, seafood, food, medicinal materials, industrial processed products, and heating greenhouses and houses. It can greatly reduce the use of electricity and other energy resources, so it can be widely promoted and used in some industries.

[0003] Utility model patent application number CN202122818346.0 discloses a solar-powered hot air generating device, including an air supply duct. Multiple heat collection devices are arranged on one side of the air supply duct. Each heat collection device includes a main frame with a right-angled triangular cross-section. The inclined surface of the main frame is the light-facing surface, and a light-transmitting plate is sealed and installed on the light-facing surface. A heat collection cavity is located between the main frame and the light-transmitting plate. This utility model adopts the above technical solution, allowing the light-facing surface to better receive sunlight and increase the irradiation area. Sunlight shines through the light-transmitting plate into the heat collection cavity. As air moves from the air inlet to the air outlet, it gradually heats up, and as the air flows within the heat collection cavity, its temperature gradually rises, thus generating hot air. However, the heat collection efficiency of this device is poor. How to improve the structure and increase the heat collection efficiency is a problem that needs to be solved. Although air inlets and outlets are opened on the shaped side plate, the wind resistance is still very high. Utility Model Content

[0004] The main technical problem to be solved by this utility model is to provide a solar thermal collector that has a reasonable structure, is easy and reliable to operate, and has high heat collection efficiency.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A solar thermal collector includes a base plate, a vertical plate and a light-transmitting plate support fixedly connected to the top of the base plate, a light-transmitting plate fixedly installed on the light-transmitting plate support, the base plate, the vertical plate, the light-transmitting plate support and the light-transmitting plate together form a heat collection cavity with a triangular cross-sectional shape, a reflective component is hinged at the connection between the vertical plate and the light-transmitting plate support, and an adjustment component for adjusting the angle of the reflective component is provided on the light-transmitting plate support near both ends.

[0007] The following are further optimizations of the above technical solution by this utility model:

[0008] The reflective assembly includes a rotating frame, in which a reflector is installed, and the rotating frame is hinged to a light-transmitting plate bracket via a hinge.

[0009] Further optimization: A reflective material layer is coated on the reflector.

[0010] Further optimization: The length and width dimensions of the reflective material layer shall not be less than the length and width dimensions of the light-transmitting plate.

[0011] Further optimization: The adjustment component includes a support base, which is fixedly connected to the light-transmitting plate bracket, and an adjustment plate is rotatably connected to the end of the support base away from the light-transmitting plate bracket.

[0012] Further optimization: An elongated hole is provided at the end of the adjusting plate away from the support base, and a support column is fixedly connected to the end face of the rotating frame. The support column is slidably sleeved in the elongated hole, and a locking nut is threaded onto the support column.

[0013] Further optimization: Fixing blocks are fixedly attached to the four corners of the base plate.

[0014] This utility model's structure, through rational design, allows sunlight reflected by the reflector to illuminate the light-transmitting plate, which, together with sunlight directly hitting the light-transmitting plate, penetrates the plate and enters the heat collection cavity, greatly improving the heat collection effect of the device. The adjustable components allow for convenient adjustment of the reflector angle according to different seasons, ensuring optimal sunlight reflection in various seasons. The absence of fixed side plates at both ends of the base plate reduces air resistance during airflow into and out of the heat collection cavity, allowing for smoother airflow within the cavity.

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments. Attached Figure Description

Detailed Implementation

[0019] like Figure 1 and 2As shown, a solar thermal collector includes a base plate 1, a vertical plate 2 and a light-transmitting plate support 3 fixedly connected above the base plate 1. The vertical plate 2 is vertically arranged, the light-transmitting plate support 3 is inclined, and a light-transmitting plate 4 is fixedly installed on the light-transmitting plate support 3. The base plate 1, the vertical plate 2, the light-transmitting plate support 3 and the light-transmitting plate 4 together form a heat collection cavity with a triangular cross-sectional shape.

[0020] Insulation boards are installed on the outer sides of the base plate 1, the upright plate 2 and the light-transmitting plate support 3. The inner surfaces of the base plate 1 and the upright plate 2 are coated with heat-absorbing layers, and the overall color of the heat-absorbing layers is black.

[0021] This allows air to flow in from one end of the heat collection chamber, gradually heat up inside the chamber, and then flow out from the other end.

[0022] This device does not have shaped side plates installed at both ends of the base plate 1, thereby reducing the wind resistance of air flowing in and out of the heat collection cavity, and making the air flow more smoothly in the heat collection cavity.

[0023] A reflective component 5 is hinged at the connection point between the upright panel 2 and the light-transmitting panel bracket 3.

[0024] With this design, sunlight reflected by the reflector 5 shines onto the light-transmitting plate 4, and together with the sunlight directly hitting the light-transmitting plate 4, penetrates the light-transmitting plate 4 and enters the heat collection cavity, greatly improving the heat collection effect of the device.

[0025] The reflective assembly 5 includes a rotating frame 501, in which a reflector 502 is installed. The rotating frame 501 is hinged to the light-transmitting plate bracket 3 via a hinge.

[0026] The reflector 502 is coated with a reflective material layer.

[0027] The length and width of the reflective material layer are not less than the length and width of the light-transmitting plate 4, thus ensuring that more sunlight can be reflected into the heat collection cavity and improving the heat collection effect of the device.

[0028] Adjustment components 6 for adjusting the angle of reflective components 5 are provided on both ends of the light-transmitting plate bracket 3.

[0029] This design allows for easy adjustment of the angle of the reflector 502 according to different seasons, thereby ensuring the best reflection effect of the adjustment component 6 on sunlight in different seasons and improving the heat collection effect of the device.

[0030] The adjustment component 6 includes a support base 601, which is fixedly connected to the light-transmitting plate bracket 3. The end of the support base 601 away from the light-transmitting plate bracket 3 is rotatably connected to an adjustment plate 603 via a connecting column 602.

[0031] An elongated hole 6031 is provided at the end of the adjusting plate 603 away from the support base 601. A support column 604 is fixedly connected to the end face of the rotating frame 501 at the position corresponding to the adjusting plate 603. The end of the support column 604 away from the rotating frame 501 is slidably sleeved in the elongated hole 6031. A locking nut 605 is threadedly connected to the support column 604.

[0032] This design allows for easy adjustment of the angle of the reflector 502 by loosening the locking nut 605. After adjustment, the locking nut 605 can be tightened, making the adjustment convenient and reliable.

[0033] Fixing blocks 7 are fixedly attached to the base plate 1 near its four corners.

[0034] This design makes it easy to stably install the device on a support, such as the ground or rooftop, where sunlight can be easily collected.

[0035] In use, multiple heat collection devices are connected in sequence to form a hot air duct. Under the suction of the blower, air enters from the cold air inlet end of the hot air duct and moves along the hot air duct towards the outlet end. The air temperature gradually rises from low temperature to high temperature and is then sent to the place where hot air is needed through the outlet.

[0036] For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of this utility model, based on the teachings of this utility model, still fall within the protection scope of this utility model.
