[0002] A solar steam generator usually includes a collector, which is used to absorb energy from solar radiation. The collector usually uses a high-absorption material, such as a solar absorption coating or a solar heat absorption tube, to convert the photothermal energy into thermal energy of a working fluid (usually a liquid, such as water or oil) in the collector, thereby increasing the temperature of the working fluid.

[0003] In the production process of solar steam generators, a pipe bending machine is needed to bend the heat exchange tube into a U shape.

[0044] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0045] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0046] The main function of the U-tube medium-temperature solar collector is to use solar energy to heat water to a medium temperature range (80-250°C), thereby providing hot water or other thermal energy utilization.

[0047] The production process of U-shaped sleeve medium temperature solar collector mainly includes the following steps:

[0048] Material preparation: Metal tube: Stainless steel, titanium alloy and other corrosion-resistant and high-temperature resistant metal materials are usually used as the outer shell of the heating tube. These materials have good thermal conductivity and mechanical strength, and can withstand high temperature and high pressure working environment. Resistance wire: Nickel-chromium alloy, iron-chromium-aluminum alloy and other resistance materials are selected. These materials have high resistivity and good oxidation resistance. Insulation material: Use magnesium oxide powder, ceramics and other insulation materials to ensure the insulation between the resistance wire and the metal tube to prevent leakage and short circuit accidents.

[0049] Processing metal pipes: Cutting: Cut the metal pipe into the required length according to the design requirements, ensuring that the cut is smooth and burr-free. Bending: Use a special pipe bending machine to bend the metal pipe into a U shape, control the bending radius and angle, and ensure that the shape of the heating pipe meets the design requirements. Welding: Weld the two ends of the bent metal pipe to form a closed U-shaped structure to ensure that the weld is firm and leak-free. Among them, the CNC platform U-shaped pipe bending machine is a pipe processing equipment that is widely used in various industries such as petrochemicals, shipbuilding, construction, and machinery manufacturing. This equipment uses CNC technology to realize automated pipe bending processing, greatly improving production efficiency and processing quality. The advantages of the CNC platform U-shaped pipe bending machine include: the use of CNC system and drive system can realize pipe bending processing and ensure the quality of the product. The use of automated processing methods can quickly complete a large number of pipe bending processing tasks, and multi-function: different molds and fixtures can be replaced according to different pipe types and bending requirements to achieve pipe bending processing of various specifications. Easy operation: The user-friendly operation interface and simple operation method enable the operator to quickly get started, improving the usability of the equipment.

[0050] Winding resistance wire: Calculate the resistance value: Calculate the required resistance wire length and resistance value according to the power and voltage requirements of the heating tube. Winding resistance wire: Wind the resistance wire on the metal tube according to the calculated length and shape, ensuring that the resistance wire is evenly distributed and without crossover.

[0051] Filling insulation material: Clean the metal pipe: remove the oil and impurities on the surface to ensure that the insulation material can be tightly combined with the metal pipe. Filling insulation material: Fill the metal pipe with insulation material such as magnesium oxide powder to ensure that the insulation material is full and has no gaps.

[0052] Sealing and testing: Sealing: Seal the two ends of the metal tube filled with insulating material, usually by welding or crimping, to ensure that the seal is firm and leak-free. Testing: Test the completed U-shaped heating tube, including electrical performance testing, insulation performance testing, pressure resistance performance testing, etc., to ensure that the quality of the heating tube meets the requirements.

[0053] Packaging and storage: Packaging: The qualified U-shaped heating tubes will be packed in cartons or wooden boxes to prevent damage during transportation and storage.

[0054] There are three forms of direct use of solar energy, namely photovoltaic, photothermal and photochemical. Although a complete industrial chain has been formed for the use of solar power generation, the most widely used form is photothermal. Although solar energy has many advantages, its disadvantages are also very obvious. For example, the energy density of solar radiation energy is low, it has a large intermittent nature, uneven spatial distribution, and is easily affected by climatic conditions and geographical environment. Therefore, the development of solar collectors is basically towards improving the efficiency of heat collection and optimizing the heat storage method. Its structure is divided into two parts: the conversion component (collector) and the storage component heat accumulator. Regarding the conversion efficiency, the collector technology is the key to the entire system. The quality and level of the collector manufacturing technology directly affect the system's ability to absorb and utilize solar energy. This article mainly discusses non-concentrating solar collectors, and can be divided into flat plate collectors and vacuum tube collectors according to whether there is a vacuum space. In order to reduce the heat exchange loss of the collector during convection, conduction and radiation, the air between the absorber and the transparent cover can be evacuated to make the space a vacuum, thus becoming a vacuum tube collector.

[0055] Solar radiation passes through the glass shell of the vacuum tube and is projected onto the inner glass tube. The selective absorption coating on the inner glass tube selectively converts solar radiation energy into heat energy. The aluminum wing acts as a bridge for heat energy conduction, transferring the heat energy to the working medium (fluid) in the "U"-shaped stainless steel pressure tube. The temperature of the working medium continues to rise, thereby further heating the water tank. At the same time, since the transfer of energy must follow the second law of thermodynamics, the heated heat absorbing tube and header will inevitably lose some heat to the surrounding environment in various ways. When the collector is in operation, solar radiation passes through the glass shell of the vacuum tube and is projected onto the inner glass tube. The selective coating on the inner glass tube converts the absorbed radiation energy into heat energy. Since the inner glass tube is in close contact with the aluminum wing, the heat energy is conducted through the aluminum wing to heat the fluid in the "U"-shaped stainless steel pressure tube. In order to facilitate the quantitative analysis of the internal heat exchange of the "U"-shaped tube collector, it is assumed that a high vacuum is maintained between the inner and outer glass tubes, the temperature of the inner and outer glass tubes remains unchanged, the heat exchange process inside the collector is in a steady state, and the air convection and heat conduction losses in the vacuum tube are ignored.

[0056] The U-shaped casing medium temperature solar collector is a device that uses solar energy to convert heat energy. Its core components include U-shaped stainless steel pressure tubes, vacuum heat collection tubes and heat transfer medium. The U-shaped stainless steel pressure tubes absorb solar energy and transfer heat. The heat transfer medium flows under the action of the circulating pump and transfers the heat to the hot water storage tank.

[0057] The working principle of the U-shaped sleeve medium temperature solar collector is as follows:

[0058] Solar energy absorption: The vacuum tube absorbs solar radiation and converts it into heat energy.

[0059] Heat transfer: Heat energy is transferred to the heat transfer medium (such as antifreeze, heat transfer oil, pure water) through the U-shaped stainless steel pressure tube, and the heat transfer medium circulates in the U-shaped tube under the action of the circulating pump.

[0060] Heat storage: The heat transfer medium brings the heat to the hot water storage tank to achieve the storage and utilization of thermal energy.

[0061] The structural features of the U-shaped sleeve medium temperature solar collector include:

[0062] U-shaped stainless steel pipe: The stainless steel pressure pipe is bent into a U shape, with both ends parallel and one end higher than the other, to facilitate the circulation of hot and cold water.

[0063] Vacuum collector tube: The interior is evacuated to reduce heat loss.

[0064] Heat transfer medium: Antifreeze is usually used, which is suitable for high-altitude and cold areas.

[0065] System connection: The solar collector systems with different lighting areas can be formed in series or parallel, which has strong adaptability.

[0066] Moreover, the U-shaped medium-temperature solar collector is suitable for various occasions that require hot water supply, such as homes, hotels, schools, etc. Its advantages include: Efficient heat transfer: The U-shaped structure makes the circulation of hot and cold water good and the heat transfer efficiency high. Strong adaptability: It is suitable for various climatic conditions, especially in high-cold areas. Easy maintenance: The system is easy to install and maintain, and can achieve fully automatic operation.
