Description

Technical Field

[0001] This utility model relates to the field of low-temperature storage cabinet technology, and specifically discloses a portable low-temperature sample storage cabinet device. Background Technology

[0002] In recent years, cryogenic storage equipment has been increasingly widely used in biomedicine, scientific research laboratories, and clinical testing to preserve temperature-sensitive materials such as vaccines, cell samples, and reagents. Most commercially available cryogenic sample storage cabinets employ a fixed design.

[0003] Traditional low-temperature sample storage cabinets typically have a single evaporator at the top or bottom of the cabinet, with cold air relying on natural convection circulation. This results in a large temperature difference between the upper and lower layers, making it difficult to meet the sample storage requirements that demand strict temperature uniformity. Furthermore, the storage partitions are mostly fixed structures and cannot be adjusted according to sample specifications. Therefore, a portable low-temperature sample storage cabinet is needed to solve this problem. Utility Model Content

[0004] This invention proposes a portable low-temperature sample storage cabinet device, which features adjustable partitions to accommodate containers of different sizes and achieve layered storage. By incorporating annular cooling pipes, precise layered cooling is achieved, ensuring uniform temperature across each layer.

[0005] This utility model is implemented as follows: a movable low-temperature sample storage cabinet device includes a cabinet body with casters at the bottom, a refrigeration system is provided at the rear of the cabinet body, and a storage mechanism is provided inside the cabinet body.

[0006] The storage mechanism includes vertical sliding grooves on the left and right sides of the inner wall of the cabinet, and the inner wall of the sliding grooves is provided with positioning holes arranged at equal intervals.

[0007] Multiple partitions are disposed between two slides, and the two sides of the partitions are detachably connected to the positioning holes of the slides by bolts.

[0008] A groove is formed around the upper edge of the partition, and an anti-slip strip is embedded inside the groove;

A quick-connect three-way valve is installed at the connection between the retractable branch pipe and the main cooling pipe. The refrigeration system also includes a compressor located at the rear of the cabinet and connected to the main cooling pipe.

[0010] As a preferred embodiment of the portable low-temperature sample storage cabinet of this utility model, the cabinet body adopts a double-layer stainless steel structure with a vacuum insulation board filling the interlayer.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0026] Please see Figure 1-5 A portable low-temperature sample storage cabinet device includes a cabinet body 1 with casters at the bottom, a refrigeration system located at the rear of the cabinet body 1, and a storage mechanism located inside the cabinet body 1.

[0027] The storage mechanism includes vertical slides 102 on the left and right sides of the inner wall of the cabinet 1, and the inner wall of the slides 102 is provided with positioning holes arranged at equal intervals.

[0028] Multiple partitions 2 are disposed between two slides 102, and the two sides of the partitions 2 are detachably connected to the positioning holes of the slides 102 by bolts.

[0029] A groove 201 is formed on the four edges of the upper end face of the partition 2, and an anti-slip strip 202 is embedded inside the groove 201;

[0030] The refrigeration system includes a main cooling pipe 301 installed inside the rear of the cabinet 1. The main cooling pipe 301 extends along the height of the cabinet 1. An annular cooling pipe 3 is installed at the bottom of each partition 2. The inlet end of the annular cooling pipe 3 is connected to the main cooling pipe 301 through a retractable branch pipe. A quick-connect three-way valve is installed at the connection between the retractable branch pipe and the main cooling pipe 301. The refrigeration system also includes a compressor 302 located behind the cabinet 1 and connected to the main cooling pipe 301.

[0031] In this embodiment: the sample that needs to be stored at low temperature is placed on the upper surface of the partition 2. The anti-slip strip 202 can prevent the sample bottle from falling. The partition 2 can be adjusted up and down inside the slide groove 102 according to the height of the sample. The partition 2 is fixed with bolts, so as to adapt to containers of different sizes and achieve the effect of layered storage.

[0032] The compressor 302 pressurizes the refrigerant into the main cooling pipe 301, which is then distributed to the annular cooling pipe 3 through the three-way valves of each layer. The cooling capacity is evenly distributed through the annular cooling pipe 3. Furthermore, by setting the annular cooling pipe 3 to connect with the compressor 302, precise stratified cooling is achieved, ensuring uniform temperature in each layer.

[0033] As a technical optimization of this utility model, the cabinet 1 adopts a double-layer stainless steel structure, with the interlayer filled with a vacuum insulation board 101.

[0034] In this embodiment, the vacuum insulation panel 101 can effectively isolate the external heat of the cabinet 1.

[0035] As a technical optimization of this utility model, a storage cavity 303 with a sealing cover on the outer wall is installed on the rear end face of the cabinet 1, the compressor 302 is installed inside the storage cavity 303, and the side wall of the storage cavity 303 is provided with heat dissipation holes with filters.

[0036] In this embodiment, the storage cavity 303 is separated from the cabinet 1 by a heat insulation plate to prevent the heat dissipation of the compressor 302 from affecting the low-temperature environment inside the cabinet. The heat dissipation holes ensure that the heat of the compressor 302 is quickly discharged during operation, while preventing dust from entering.

[0037] As a technical optimization of this utility model, the front end of the cabinet 1 is hinged with a double-layer hollow glass door 104, and the inner edge of the door 104 is inlaid with a magnetic rubber sealing strip, which is magnetically attached to the metal frame at the opening of the cabinet 1.

[0038] In this embodiment: the magnetic rubber sealing strip on the cabinet door 104 automatically adheres to the cabinet body 1 when the door is closed, reducing cold air leakage.

[0039] As a technical optimization of this utility model, a battery 4 is provided on the rear end face of the cabinet 1, located on the upper end face of the storage cavity 303. The battery 4 is connected to the compressor 302 circuit through a physical switch.

[0043] The working principle and usage process of this utility model are as follows: The sample that needs to be stored at low temperature is placed on the upper surface of the partition 2. The anti-slip strip 202 can prevent the sample bottle from falling. The partition 2 can be adjusted up and down inside the slide groove 102 according to the height of the sample. The partition 2 is fixed with bolts, so as to adapt to containers of different specifications and achieve the effect of layered storage.

[0044] Next, the branch pipe is connected to the inlet end of the annular cooling pipe 3. The refrigerant is pressed into the main cooling pipe 301 by the compressor 302 and distributed to the annular cooling pipe 3 through the three-way valves of each layer. The cooling capacity is evenly distributed through the annular cooling pipe 3. Furthermore, by setting the annular cooling pipe 3 and connecting it with the compressor 302, precise layered cooling is achieved to ensure uniform temperature of each layer.

[0045] Pull the lever 103 outward to unfold it, and then use the casters to move the cabinet 1 to the desired position.
