Description

Technical Field

[0001] This utility model belongs to the field of cold air distribution pipes, specifically a cold air distribution pipe for cold storage refrigeration. Background Technology

[0002] Cold storage is a type of refrigeration equipment. It refers to an environment created artificially that differs from the outdoor temperature or humidity. Refrigeration pipes are indispensable in the use of cold storage. After prolonged use, frost will form on the surface of the refrigeration pipes. Excessive frost accumulation will increase the weight of the refrigeration pipes, posing a risk of collapse and affecting heat exchange efficiency. Therefore, defrosting is necessary. There are various methods for defrosting refrigeration pipes, but the frost produced by current defrosting methods falls directly to the ground. Cold storage facilities need to allocate necessary space for defrosting, making cleaning inconvenient. Therefore, we have designed a refrigeration pipe for cold storage that facilitates the cleaning of frost. Utility Model Content

[0003] This utility model provides a cold storage refrigeration pipe to overcome the deficiencies in the prior art.

[0004] This utility model is achieved through the following technical solution:

[0005] A refrigeration radiator for cold storage includes a radiator coil, which is a serpentine coil formed by connecting several straight and bent pipes. Below each straight pipe of the radiator coil, there is an arc-shaped plate that can conduct heat to it. One end of the arc-shaped plate is open and the other end is closed. Support shafts are fixedly installed on the arc-shaped plates. The ends of the support shafts on the same side are rotatably connected to the same mounting plate. A motor is fixedly installed on one of the mounting plates. The output shaft of the motor is coaxially fixedly connected to one of the support shafts. The several support shafts are connected by a transmission mechanism.

[0006] As described above, in a cold storage refrigeration pipe, the transmission mechanism includes connecting rods, with connecting rods fixedly mounted on a support shaft, and one end of each connecting rod hinged to the same connecting plate.

[0007] As described above, a cold storage refrigeration pipe has several heat-conducting plates fixedly installed on it. One end of each heat-conducting plate is arc-shaped and can fit into a corresponding arc-shaped plate.

[0008] As described above, in a cold storage refrigeration pipe, several of the aforementioned arc-shaped plates are arranged at an angle.

[0009] As described above, a cold storage refrigeration pipe has heat dissipation fins fixedly installed on the top of each straight pipe.

[0010] In the cold storage refrigeration pipe described above, the distance between two adjacent arc-shaped plates is the same as the diameter of the arc-shaped plate.

[0011] The advantages of this utility model are: the structure is simple and the design is ingenious. The frost and melted water falling from the radiator pipe can drip into the arc-shaped plate and then fall into one place from one end of the semi-circular opening, making cleaning more convenient. The cleaning process will not take up too much space, making it more practical. The arc-shaped plate can also serve as a heat-conducting component, increasing the heat dissipation area and improving the cooling effect. It can meet actual needs and is suitable for promotion. When using this device, the radiator pipes are mounted on the ceiling of the cold storage room using the existing mature technology of the matching brackets. The mounting plate is then installed on the wall of the cold storage room according to the dimensions of the radiator pipes. After a period of use, when defrosting is required, a motor drives one of the support shafts to rotate, which in turn drives the other support shafts to rotate, causing the arc-shaped plate to rotate until its axial opening aligns with the radiator pipes. Melted water and frost from the radiator pipes then fall into the arc-shaped plate and are collected. As the water and frost flow, they fall from the opening at the end of the arc-shaped plate to a concentrated location, making frost removal easier. Once the frost has been cleared, the motor rotates in the opposite direction, resetting the arc-shaped plate. At this point, the arc-shaped plate can exchange heat with the radiator pipes, increasing the heat exchange area and improving the cooling effect of the cold storage room.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] A type of refrigeration pipe for cold storage, such as Figure 1 , 2 As shown in Figures 3, 4, and 5, the device includes a radiator tube 1, which is a serpentine coil formed by connecting several straight and bent tubes. This is a mature existing technology and will not be described in detail here. Below each straight tube of the radiator tube 1, there is an arc-shaped plate 2 that can conduct heat to it. One end of the arc-shaped plate 2 is open and the other end is closed. Support shafts 3 are fixedly installed on the arc-shaped plates 2. The support shafts 3 are coaxially arranged with the corresponding arc-shaped plates 2. One end of the support shaft 3 is fixedly connected to one end of several connecting rods. The other end of the connecting rods is fixedly connected to the inner wall of the open end of the arc-shaped plate 2. The other end of the support shaft 3 is fixedly connected to the closed end of the arc-shaped plate 2. The same side end of the support shaft 3 is rotatably connected to the same mounting plate 4. Several mounting holes are opened on the mounting plate 4. The ends of the support shafts 3 are rotatably connected to the corresponding mounting holes through bearings. A motor 5 is fixedly installed on one of the mounting plates 4. The motor 5 is fixedly installed on a connecting plate. The connecting plate is fixedly installed on the mounting plate 4. The output shaft of the motor 5 is coaxially fixedly connected to one of the support shafts 3. The several support shafts 3 are connected by a transmission mechanism. This utility model has a simple structure and ingenious design. The frost and melted water that fall off the radiator pipe 1 during defrosting can drip into the arc plate 2 and then fall into one place from one end of the semicircle 2 opening, making cleaning more convenient and not taking up too much space. It is more practical. The arc plate 2 can also be used as a heat-conducting component to increase the heat dissipation area and improve the cooling effect. It can meet practical needs and is suitable for promotion. When using this device, the radiator pipe 1 is installed on the ceiling of the cold storage using the bracket provided with it, which is a mature existing technology. Then, the installation position of the mounting plate 4 is determined according to the size of the radiator pipe 1. The mounting plate 4 is installed on the wall of the cold storage by drilling or welding. When the radiator pipe 1 needs to be defrosted after a period of use, the motor 5 drives one of the support shafts 3 to rotate, and then the transmission mechanism drives the other support shafts 3 to rotate together, so that the arc plate 2 rotates together until the axial opening of the arc plate 2 is aligned with the radiator pipe 1. The melted water and frost from the radiator pipe 1 can fall into the arc plate 2 and be collected. With the flow of water and frost, they can fall from the opening at the end of the arc plate 2 to a certain place, making the frost fall more concentrated and easier to handle. After the frost is cleared, the motor 5 is rotated in the opposite direction to reset the arc plate 2. At this time, the arc plate 2 can exchange heat with the radiator pipe 1, increasing the heat exchange area and improving the cooling effect of the cold storage.

[0017] Specifically, as shown in the figure, the transmission mechanism in this embodiment includes connecting rods 20. Connecting rods 20 are fixedly installed on the support shafts 3, and one end of each connecting rod 20 is hinged to a connecting plate 21. When the motor 5 drives the corresponding support shaft 3 to rotate, the support shaft 3 will drive the corresponding connecting rod 20 to rotate together, and through the hinged connecting plate 21, it will drive the other connecting rods 20 to rotate together, thereby causing all the support shafts 3 and the arc plate 2 to rotate together.

[0018] Specifically, as shown in the figure, several heat-conducting plates 30 are fixedly installed on the radiator pipe 1 in this embodiment. One end of the heat-conducting plate 30 is arc-shaped and can fit into the corresponding arc-shaped plate 2. The arc-shaped end of the heat-conducting plate 30 is coaxially arranged with the arc-shaped plate 2. When the arc-shaped plate 2 is used as a heat-conducting component, the arc-shaped plate 2 rotates so that its outer circumference fits into the corresponding heat-conducting plate 30. The heat of the radiator pipe 1 can then be transferred to the arc-shaped plate 2 through the heat-conducting plate 30, increasing the heat exchange area and improving the refrigeration effect of the cold storage. Through the heat conduction of the heat-conducting plate 30, the arc-shaped plate 2 is prevented from directly contacting the radiator pipe 1 over a large area, reducing the possibility of the radiator pipe 1 freezing together with the arc-shaped plate 2 due to frost. At the same time, friction between the arc-shaped plate 2 and the radiator pipe 1 is also avoided, reducing wear and deformation caused by friction, making it safer to use.

[0019] Furthermore, as shown in the figure, in this embodiment, several of the arc-shaped plates 2 are inclined, and the heat-conducting plates 30 on the radiator pipe 1 have different lengths so that they can fit in close contact with the arc-shaped plates 2. When the radiator pipe 1 defrosts and the arc-shaped plates 2 collect the falling frost, the inclined arc-shaped plates 2 cause the frost and water falling on them to flow and fall out from the opening at one end, preventing frost from accumulating inside the arc-shaped plates 2.

[0020] Furthermore, as shown in the figure, heat dissipation fins 50 are fixedly installed on the top of the straight pipe of the cold radiator 1 in this embodiment. The heat dissipation fins 50 can increase the heat exchange area and improve the cooling effect in the cold storage.

[0021] Furthermore, as shown in the figure, in this embodiment, the distance between two adjacent arc-shaped plates 2 is the same as the diameter of the arc-shaped plate 2. This same distance ensures that the arc-shaped plates 2 are close together when collecting frost and water, and the small gap between adjacent arc-shaped plates 2 prevents frost from falling through the gaps, thus guaranteeing that the frost can be collected.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
