Technical Field

[0001] The utility model relates to the technical field of heat exchange, in particular to a greenhouse heat exchange pipe structure. Background Art

[0002] Large greenhouses can easily experience internal temperatures rising on sunny days. Excessively high temperatures are not ideal for plant growth and negate the greenhouse's constant temperature advantage. Therefore, existing greenhouses use ventilation and other methods to expel hot air for cooling. While this approach does help, it wastes significant amounts of heat energy. At night, when ambient temperatures are lower, heating systems are required to maintain internal temperatures, further increasing energy consumption.

[0024] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," etc., etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] like Figure 1 As shown, a greenhouse heat exchange tube structure includes a heat exchange tube 1, wherein a plurality of partition plates 2 are provided inside the heat exchange tube 1, wherein the partition plates 2 are arranged along the length direction of the heat exchange tube, and the partition plates 2 divide the internal space of the heat exchange tube 1 into a plurality of ventilation cavities 3 arranged along the length direction; the heat exchange tube 1 is a metal tube, and the partition plates 2 are metal plates, and the partition plates 2 are welded to the heat exchange tube 1.

[0027] The greenhouse heat exchange tube structure is configured with a plurality of partition plates 2 in the heat exchange tube 1, which not only can separate the interior of the heat exchange tube into a plurality of ventilation chambers, but also can increase the contact area between the inflowing air and the partition plates and the heat exchange tube. This is beneficial to increasing the area for heat exchange between the air in the heat exchange tube and the cooling medium outside the heat exchange tube, thereby greatly improving the heat exchange efficiency and effect without affecting the air flow speed and smoothness; moreover, the structure of the entire heat exchange tube is not complicated and is easy to manufacture, install and use.

[0028] Since the greenhouse heat exchange tube structure has good heat exchange and ventilation capabilities, the heat exchange tube can be used in a glass greenhouse to exchange heat with the hot air in the glass greenhouse, collect and store heat energy, and discharge room temperature air at the same time, thereby improving the temperature in the glass greenhouse through circulation and heat exchange.

[0029] The dividers 2 are arranged along the length of the tube. Multiple dividers 2 can multiply the surface area within the tube, significantly increasing the contact area between air and metal. This prevents any obstruction in the cross-sectional area, preventing air from flowing normally. The heat exchange tubes not only have straight tube structures but also have curved tube structures at bends or reversals. These curved tube structures can also contain dividers. The dividers within these curved tube structures form an arc-shaped structure along the length of the tube.

[0030] The heat exchange tube 1 and the partition plate 2 are both made of the same metal material, such as steel, aluminum or copper, and preferably aluminum tubes and aluminum plates are used, which have good heat transfer function, are light and easy to weld, and are convenient for production and installation.

[0031] In some embodiments, the heat exchange tube 1 is a box structure with a rectangular cross-section, including a box body 4 with an opening at the top, and a box cover 5 with a sealing cover provided on the opening. The partition plate 2 is arranged obliquely in the box body 4, and one end of the partition plate 2 is connected to the box body 4 and the other end is connected to the box cover 5.

[0032] At least one end of the partition plate 2 is welded and fixed to the box body 4 or the box cover 5 , and the box cover 5 is sealed and welded to the box body 4 . There are no less than three partition plates 2 .

[0033] This rectangular box-shaped heat exchange tube is relatively easy to manufacture and inexpensive. The connection and docking of the tube openings are also relatively simple, and the aspect ratio can be adjusted to meet the heat exchange requirements of different volumes. The box and the cover are manufactured separately. After welding the partition plate to the bottom of the box, the cover is installed, and then the cover is welded to the box. Alternatively, the partition plate can be welded to the inside of the cover, then installed in the box and welded to seal.

[0034] The partition plate 2 in the box body 4 is arranged at an angle, which has a larger contact area compared to a vertical or horizontal arrangement, and can form a triangular stable structure in the box body, which is beneficial to improving the overall strength and stability, so that it can withstand the pressure from the external cooling medium; at the same time, the partition plate can also support the box cover.

[0035] Furthermore, the adjacent partition plates 2 are arranged in opposite inclination directions, and a plurality of the partition plates 2 are continuously arranged to form a wavy structure, so that the ventilation cavities separated by the adjacent partition plates are all triangular structure cavities with higher stability.

[0036] In other embodiments, Figure 2As shown, the heat exchange tube 1 is a cylindrical structure with a circular cross section, including a semicircular tube body 6 set in half, and the semicircular tube body 6 is provided with the inclined and vertically distributed partition plates 2, or the partition plates 2 passing the heat exchange tube diameter line.

[0037] While the circular heat exchange tube 1 is relatively complex to manufacture, it offers smooth inner and outer surfaces, no corners, minimal wind resistance, and theoretically no eddy currents. It also offers superior strength and pressure-bearing capacity. The internal, angled partitions further enhance structural strength and stability, while also multiplying the internal surface area.

[0038] Furthermore, at least one partition plate 2 is arranged in the middle of a pair of the semicircular tubes 6, and the butt end faces of the pair of the semicircular tubes 6 respectively abut against the partition plate and are welded and fixed. At least two partition plates are also provided in each of the semicircular tubes 6.

[0039] The semicircular tube 6 of the half-formula is relatively easy to batch produce, and is also convenient for butt welding into one. The middle partition plate is except its separation function, and is also convenient for the butt end face welding of a pair of semicircular tubes at its both sides, and does not need to be provided with flange on the semicircular tube.

[0040] Furthermore, the angle between the inclined partition plate 2 and the vertical surface is 15 to 30 degrees.

[0041] Furthermore, the partition plate 2 is a 1 mm thick plate, and the thickness of the partition plate 2 is not greater than the wall thickness of the heat exchange tube 1. The length and width of the heat exchange tube can be 100-500 mm, or the diameter does not exceed 600 mm.

[0042] Further, such as Figure 3 As shown, a plurality of heat exchange fins 7 are provided on the outer periphery of the heat exchange tube 1. The arrangement of these fins 7 can increase the heat exchange efficiency between the heat exchange tube and the external heat exchange medium, thereby improving the heat exchange capacity of the air.

[0043] Further, such as Figure 4 As shown, a plurality of metal tube supports 8 are provided below the heat exchange tube 1 at intervals along its length direction. The heat exchange tube 1 can be arranged in a circuitous manner in the energy storage tank 9 of the greenhouse to increase the heat exchange path.

[0044] The energy storage water tank 9 is usually arranged underground in a glass greenhouse and can accommodate a large amount of water. The heat exchange tube 1 is arranged therein, and the heat energy in the air can be stored in the water of the energy storage water tank through heat exchange between water and air, so as to achieve the purpose of energy recycling, energy saving and environmental protection, which is beneficial to the ambient temperature control of the glass greenhouse. The energy storage water tank has a certain thermal insulation effect, can better retain heat, and the relatively closed structure can also reduce water evaporation.

[0045] The metal pipe support 8 is provided to support the heat exchange tube 1 on one hand, so that the heat exchange tube 1 is not in contact with the inner wall of the energy storage tank and the water is surrounded by the outer periphery. On the other hand, it can fix the heat exchange tube 1 to prevent the heat exchange tube 1 from shaking or floating. The bottom of the metal pipe support 8 is provided with a mounting base, which can be fixedly connected to the energy storage tank by anchor bolts or bolts. The top of the metal pipe support 8 can be a supporting flat plate or a supporting arc plate, which is welded and fixed to the heat exchange tube 1, or it can be a supporting clamping structure with a clamping groove to clamp and fix the heat exchange tube 1.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
