Description

Technical Field

[0001] This utility model relates to the field of ultra-low temperature automated storage equipment technology, specifically a cold source coil. Background Technology

[0002] The storage cavity of an automated single-unit refrigerator is divided into a storage layer and an equipment layer. The temperature of the storage layer needs to be controlled at -80℃, while the equipment layer, composed of mechanical components, is the main structure for automated sample handling. In ultra-low temperature environments, these mechanical structures are prone to failure and shutdown; therefore, the temperature of the equipment layer needs to be controlled at -40℃. Existing equipment has the following drawbacks: due to the sinking of cold air, the heat emitted by the equipment layer when it is working at the top of the cryopreservation rack is easily transferred to the low-temperature area where the cryopreservation rack is located, causing the temperature around the cryopreservation rack to rise, which in turn affects the preservation quality of biological samples in the cryopreservation tubes. Traditional refrigerator structures lack effective isolation and cooling measures, and cannot effectively isolate the heat generated by the equipment layer from the cryopreservation rack area, making the temperature control inside the refrigerator not precise enough and difficult to meet the requirements for long-term stable preservation of biological samples.

[0003] Therefore, this application proposes a cold source coil to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a cold source coil to solve the problem that the heat emitted by the equipment layer during operation can easily be transferred to the low-temperature area where the freezer rack is located, causing the temperature around the freezer rack to rise.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cold source coil, comprising: The partition unit is installed inside the automated single-unit refrigerator body to separate the upper equipment layer of the automated single-unit refrigerator body from the freezer rack. The partition unit includes: Top boxes are spaced apart inside the automated single-unit refrigerator body near the equipment layer, and a walking passage for the equipment layer to move is provided between the two top boxes; A partition foam board is installed inside the top box to isolate the heat dissipated by the upper equipment layer of the automated single-unit refrigerator when it is working; A condensing component is located at the lower end of the partition foam board and is used to cool the area below the partition foam board.

[0006] The partition unit further includes: A fixing component, disposed on the condensing component, is used to fix the condensing component to the top box; The fixing component includes mounting bases symmetrically arranged with respect to the top box and fixing buckles disposed on both sides of the mounting bases for fixing the mounting bases to the top box.

[0008] Wherein, a limit block is provided at the position where the pull-out box is connected to the mounting base, and a limit groove is provided on the mounting base for the limit block to move; The mounting base is provided with an abutment plate on the side away from the door to limit the depth of the pull-out box inserted into the mounting base; An extension plate is provided at the upper end of the mounting base, and the extension plate is fixedly connected to the top box by mounting bolts.

[0009] The fixing buckle includes: A fixed frame is spaced out on the mounting base; The mounting shaft is located inside the fixed frame; A rotating plate is disposed on the side of the mounting shaft and close to the pull-out box and inserted into the pull-out box; The top plate is located on the side of the rotating plate away from the mounting axis and is snapped onto the side edges of both sides of the top box; The top plate is fixedly connected to the side by fixing bolts.

[0010] The pull-out box has mounting holes on both sides corresponding to the positions of the rotating plate for mounting the rotating plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: The partition unit of this utility model's cold source coil constructs a highly efficient heat insulation barrier through the partition foam board inside the top box. The partition foam board has excellent heat insulation performance, which can significantly reduce the heat transfer from the operating parts to the cryopreservation rack, creating a stable, low-temperature storage environment for biological samples and effectively ensuring the activity and integrity of the samples. The condensation component is located at the lower end of the partition foam board, directly cooling the cryopreservation rack area below the partition foam board. It can control the temperature around the cryopreservation rack, ensuring that the temperature at the top and bottom of the cryopreservation rack is within a suitable range, thus improving the refrigeration effect of the refrigerator.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-8This utility model provides a technical solution: a cold source coil, comprising: a partition unit 3, disposed inside the automated single-unit refrigerator body 1, for separating the upper equipment layer of the automated single-unit refrigerator body 1 from the freezer rack 2; the partition unit 3 includes: a top box 31, spaced apart inside the automated single-unit refrigerator body 1 near the equipment layer, with a walking channel 101 between the two top boxes 31 for allowing the equipment layer to move; a partition foam board 32, disposed inside the top box 31, for isolating the heat dissipated by the upper equipment layer of the automated single-unit refrigerator body 1 during operation; and a condensation assembly, disposed at the lower end of the partition foam board 32, for cooling the area below the partition foam board 32.

[0016] It should be noted that during operation, a partition unit 3 is installed between the equipment layer and the storage layer of the automated single-unit refrigerator body 1. The top box 31 is installed at intervals on the top of the equipment travel channel 101. Then, the partition foam board 32 is fixed to the lower end of the top box 31, and the condenser assembly is installed below the top box 31. A temperature sensor is installed at the lower end of the equipment layer to detect the temperature below the equipment layer. The temperature sensor is electrically connected to the condenser assembly through a PLC control element. When the temperature below the equipment layer exceeds a set value, the sensor transmits a signal to the PLC control element, which then opens the condenser assembly to cool the area below the equipment layer. In the automated single-unit refrigerator body 1, the upper operating components generate heat during operation. If this heat is transferred to the cryopreservation rack 2 area below, it will seriously affect the preservation quality of biological samples in the cryopreservation tubes. The partition unit 3 of this cold source coil constructs an efficient heat insulation barrier through the partition foam board 32 in the top box 31. The partition foam board 32 has good heat insulation performance, which can significantly reduce the heat transfer of the operating parts to the cryopreservation rack 2, creating a stable and low-temperature storage environment for biological samples, effectively ensuring the activity and integrity of the samples. The condensation component is located at the lower end of the partition foam board 32, directly cooling the cryopreservation rack 2 area below the partition foam board 32, which can control the temperature around the cryopreservation rack 2, ensuring that the temperature of the top and bottom of the cryopreservation rack 2 is within a suitable range, thus improving the refrigeration effect of the refrigerator.

[0017] In one embodiment, the partition unit 3 further includes: a fixing component 34 disposed on the condensing component for fixing the condensing component to the top box 31; the fixing component 34 includes a mounting base 341 symmetrically disposed about the top box 31 and fixing buckles 342 disposed on both sides of the mounting base 341 for fixing the mounting base 341 to the top box 31.

[0018] This design is for reference. Figure 3-8The fixing component 34 is installed on the condensing component and is used to fix the condensing component to the top box 31. When installing the condensing component, the condensing component is fixed inside the mounting base 341, and then the top of the condensing component is aligned with the top box 31. Then, the mounting base 341 is fixed to the top box 31 by the fixing buckle 342, thereby realizing the fixing of the condensing component to the top box 31. The mounting base 341 is symmetrically arranged about the top box 31. With the fixing buckle 342 on both sides, it can provide multiple directions of constraint force for the condensing component, effectively preventing the condensing component from being displaced or shaking due to factors such as refrigerator vibration and stress caused by temperature changes during refrigeration. This ensures that the condensing component is always in the correct installation position, can stably perform the refrigeration function, and ensures the reliability of the overall performance of the cold source coil.

[0019] In one embodiment, the condensation assembly includes: a bottom box 33 disposed below the top box 31 for mounting the partition foam board 32 and the condensation assembly; the bottom box 33 includes a pull-out box 331 slidably disposed inside the mounting base 341 and a condenser pipe 333 disposed inside the pull-out box 331, and the condenser pipes 333 inside the multiple pull-out boxes 331 are connected to each other.

[0020] This design is for reference. Figure 5 ,as well as Figure 8 The bottom box 33 is located below the top box 31, providing a stable installation position for the partition foam board 32 and the condenser assembly. The bottom box 33 includes a pull-out box 331, which enables modular installation of the condenser assembly. The pull-out box 331 can be installed and debugged independently. During production, components such as the condenser tube 333 can be installed in the pull-out box 331 first, and then the pull-out box 331 can be installed as a whole in the position of the bottom box 33, simplifying the installation process and improving installation efficiency and accuracy. The pull-out box 331 is slidably set inside the mounting base 341. This design makes maintenance and repair work extremely convenient. When the condenser tube 333 malfunctions or requires regular maintenance, the staff does not need to disassemble the entire refrigerator on a large scale. They can simply pull out the pull-out box 331 from the mounting base 341 to directly inspect, repair, or replace the condenser tube 333, shortening maintenance time, reducing losses caused by equipment downtime, and lowering operation and maintenance costs.

[0021] In one embodiment, a limiting block 332 is provided at the position where the pull-out box 331 is connected to the mounting base 341, and a limiting groove 34101 is provided on the mounting base 341 for the limiting block 332 to move; an abutment plate 3411 is provided on the side of the mounting base 341 away from the box door 11 for limiting the depth of the pull-out box 331 inserted into the mounting base 341; an extension plate 3412 is provided at the upper end of the mounting base 341, and the extension plate 3412 is fixedly connected to the top box 31 by mounting bolts 3413.

[0022] This design is for reference. Figure 7 Install the mounting bolt 3413 in the extension plate 3412, and then fix it in the fixing hole 3101 opened on the top box 31 to complete the fixing work between the mounting base 341 and the top box 31. Set the limiting block 332 at the connection position between the pull-out box 331 and the mounting base 341. At the same time, the mounting base 341 is opened with a limiting groove 34101 for the limiting block 332 to move. This design provides precise guidance for the pull-out operation of the pull-out box 331. When the operator pulls out or pushes in the pull-out box 331, the limiting block 332 slides in the limiting groove 34101, which can effectively prevent the pull-out box 331 from deviating or shaking during the movement, and ensure that the pull-out operation is stable and smooth, and align the extension plate 3412 with the top box 31.

[0023] In one embodiment, the fixing buckle 342 includes: a fixing frame 3421, spaced apart on the mounting base 341; a mounting shaft 3422, disposed inside the fixing frame 3421; a rotating plate 3423, disposed on the mounting shaft 3422 and inserted into the pull-out box 331 on the side closer to the pull-out box 331; and a top plate 3424, disposed on the side of the rotating plate 3423 away from the mounting shaft 3422 and snapped onto the side edges 311 on both sides of the top box 31. The top plate 3424 is fixedly connected to the side edges 311 by fixing bolts 3425. The side edges 311 are provided with connecting holes 31101 for installing the fixing bolts 3425. The rotating plate 3423 is provided with pressing blocks 3426 for the operator to adjust the rotation of the rotating plate 3423.

[0024] This design is for reference. Figure 6-8 When the pull-out box 331 is inserted into the mounting base 341, the rotating plate 3423 is flipped along the mounting shaft 3422 to the side away from the mounting base 341, providing space for the pull-out box 331 to be inserted into the mounting base 341. After the pull-out box 331 is installed in the set position of the mounting base 341, the rotating plate 3423 is rotated in the opposite direction, and then the bottom of the rotating plate 3423 is inserted into the pull-out box 331. The top plate 3424 is fixedly connected to the side edges 311 on both sides of the top box 31 by fixing bolts 3425, completing the fixing of the pull-out box 331 and the top box 31. The entire installation process is clear and simple to operate, requiring no complicated tools and techniques, shortening the installation time and improving production efficiency.

[0025] In one embodiment, mounting holes 33101 for mounting the rotating plates 3423 are provided at the corresponding positions of the rotating plates 3423 on both sides of the pull-out box 331.

[0026] This design is for reference. Figure 6Mounting holes 33101 are provided at the corresponding positions of the rotating plates 3423 on both sides of the pull-out box 331, providing mounting positions for the rotating plates 3423. During assembly, the rotating plates 3423 are inserted into the mounting holes 33101 to achieve docking between the pull-out box 331 and the rotating plates 3423, which shortens the installation time and improves production efficiency.
