Description

Technical Field

[0001] This utility model relates to the field of cryopreservation rack technology, specifically a cryopreservation rack cold storage partition. Background Technology

[0002] Automated stand-alone refrigerators are frequently used in fields such as biomedicine and clinical testing. An automated stand-alone refrigerator contains one or more individually controlled ultra-low temperature storage compartments.

[0003] Four cryopreservation racks are placed side by side in an ultra-low temperature storage chamber to achieve orderly storage of biological samples in a low-temperature environment. The maintenance of sample viability requires extremely high temperature stability, and it is necessary to ensure that the cryopreservation rack area is continuously in a uniform ultra-low temperature environment.

[0004] The main problem is uneven cooling between the two cryogenic racks, which is caused by two main reasons. First, within the ultra-low temperature storage chamber, due to the sinking of cold air, there is a gradually decreasing temperature gradient from bottom to top, resulting in uneven distribution of cooling airflow and temperature differences between the freezing points on different layers of the cryogenic racks. Second, the spacing between the two middle cryogenic racks is too small, leading to uneven cooling at the gap between them.

[0005] The problem with existing technology is that it cannot accurately cool the intervals between cryogenic racks, resulting in uneven cooling between two cryogenic racks. Utility Model Content

[0019] 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.

[0020] See Figures 1-6 This utility model provides a technical solution: a cryogenic storage rack cold storage partition, comprising: The partition body 1 is located between two cryopreservation rack bodies 4. The cryopreservation rack body 4 includes several sample plates arranged side by side along the height direction. Mounting component 2 is used to place the partition body 1 into the refrigerator body 5; The cooling channel 3 is set in the partition body 1 and includes an inlet 31 and an outlet 32. The outlet 32 ​​includes an outlet one and an outlet two. After the refrigerant enters the cooling channel 3 from the inlet 31, it is discharged to the freezer body 4 on one side through the outlet one and to the freezer body 4 on the other side through the outlet two. Each sample plate is equipped with at least one cooling channel 3.

[0021] It should be noted that the shelf body 1 is placed in the refrigerator body 5 using the mounting component 2, so that the shelf body 1 is located between the two freezer rack bodies 4 in the middle. The freezer rack bodies 4 of the refrigerator body 5 are fixed inside the refrigerator body 5. After installation, each shelf corresponds to one cooling channel 3. The inlet 31 is connected to an external pipe for supplying refrigerant to the inlet 31. The refrigerant reaches the outlet 32 ​​through the cooling channel 3. The refrigerant discharged from the outlet 32 ​​enters the corresponding height of the freezer rack body 4. Refrigerant can be precisely replenished at different heights of the shelf as needed to improve the cooling uniformity between the two freezer racks. Because the outlet 1 and outlet 2 of a cooling channel 3 point in opposite directions, and the cooling channel 3 is opened inside the shelf body 1, several cooling channels 3 are arranged side by side to avoid interference between adjacent cooling channels 3.

[0022] In one or more embodiments, the cooling channel 3 is provided with a cooling air regulating component 6, and rotating the cooling air regulating component 6 controls the opening and closing of the first discharge port and the second discharge port.

[0023] This design is for reference. Figure 1-3 It can control the opening or closing of outlet 1 and outlet 2 simultaneously, or control the opening of either outlet 1 or outlet 2. Thus, for the two sample plates located at the same height, the outlet 32 ​​on one side can be controlled to open or close independently. When only one sample plate is placed, only the outlet 32 ​​on that side consumes refrigerant, thus achieving energy saving.

[0024] In one or more embodiments, the height of the vertical section a in the equipped cooling channel 3 is set according to the height of the sample plate.

[0025] This design is for reference. Figure 3 The cooling channel 3 is located inside the partition body 1. Therefore, the height of the cooling channel 3 used in conjunction with the sample placement plate is different depending on the height of the sample placement plate, so that the refrigerant can be delivered to the target sample placement plate.

[0026] In one or more embodiments, the cooling channel 3 includes a vertical section a, and the discharge port 31 is located at the top of the vertical section a; The air conditioning regulating component 6 includes a rotating cylinder 60, a first spur gear 61, a second spur gear 62, and a rotating shaft 63. The rotating cylinder 60 is fitted inside the vertical section a. The first spur gear 61 is fitted on the rotating cylinder 60. The second spur gear 62 and the rotating shaft 63 are both rotatably disposed inside the partition body 1. The second spur gear 62 meshes with the first spur gear 61. One end of the rotating shaft 63 is connected to the second spur gear 62, and the other end extends to the top of the partition body 1 and is provided with a handle 8. The rotating cylinder 60 is provided with through holes 601 and 602 in sequence along the first radial direction; the rotating cylinder 60 is also provided with a second radial direction, and the rotating cylinder 60 is provided with a solid part 603 along the second radial direction.

[0027] This design is for reference. Figure 1-4 In a cooling channel 3: the refrigerant flows downward through the inner annular surface of the rotating cylinder 60. The outer wall of the rotating cylinder 60 is in contact with the inner wall of the cooling channel 3, preventing the refrigerant from passing through the gap between the rotating cylinder 60 and the cooling channel 3, thus better preventing refrigerant leakage. Turning the handle 8 causes the rotating shaft 63 and the second spur gear 62 to rotate synchronously. The second spur gear 62 meshes with the first spur gear 61, driving the rotating cylinder 60 to rotate. While the cylinder 60 is rotating, the through hole 601 connects to the discharge port 32 on one side. At the same time, the second through hole 602 in the first radial direction is also connected to the discharge port 32 on the other side. The refrigerant through hole 601 and the second through hole 602 enter the discharge holes on both sides respectively, and are discharged from the discharge port 32 to the corresponding height of the freezer body 4. Continue to rotate the rotating cylinder 60 until the first through hole 601 and the second through hole 602 are no longer connected to the discharge port. At this time, the solid part 603 plays a blocking role. The solid part 603 blocks the refrigerant in the cooling channel 3. After being blocked, the discharge port 32 stops discharging refrigerant.

[0028] In one or more embodiments, the angle between the first radial direction and the second radial direction is 60 to 90 degrees.

[0029] This design is for reference. Figure 4 Through holes 601 and 602 have a certain width, and the angle between the first radial direction and the second radial direction is 60 to 90 degrees, which can ensure that there is sufficient gap between through holes 601 and 602 for setting solid part 603. The refrigerant can be gas or liquid. When it is liquid, the refrigerant discharged from the outlet 32 ​​will collect at the bottom of the refrigerator and be discharged from the storage compartment through the circulation device.

[0030] In one or more embodiments, the rotating cylinder 60 is further provided with a third radial direction, the second radial direction being located between the first radial direction and the third radial direction, the included angle between the two adjacent directions being 60 degrees, and the rotating cylinder 60 is provided with a through hole 604 and a solid part 605 along the third radial direction.

[0031] This design is for reference. Figure 1-3 and Figure 5 In a cooling channel 3: the line connecting the left and right outlets 1 and 2 at their center points is the working line; the rotating cylinder 60 is driven to rotate by the cooling air regulating component 6. When the first radial direction of the rotating cylinder 60 is parallel to the working line, outlets 1 and 2 can be opened simultaneously; when the second radial direction is parallel to the working line, outlets 1 and 2 can be closed simultaneously; when the third radial direction is parallel to the working line, either outlet 1 or outlet 2 can be opened arbitrarily, thereby controlling the height and direction of the refrigerant flow. Regarding the through hole 3 604 and the solid part 2 605, when the through hole 3 604 is connected to either of the left or right outlets 32, the refrigerant is discharged from that outlet 32, and the solid part 605 located opposite the through hole receiving 604 blocks the other outlet 32.

[0032] In one or more embodiments, the feed inlet 31 is located at the top of the partition body 1. The feed inlet 31 is connected to a refrigerant supply device inside the refrigerator body 5 or to an external refrigerant supply device to deliver refrigerant to the feed inlet 31.

[0033] In one or more embodiments, the cooling channel 3 further includes a curved section b and an inclined section c, the curved section b being located between the vertical section a and the inclined section c, the inclined section c being located between the corresponding discharge port 32 and the curved section b, and the discharge port 32 of the inclined section c pointing obliquely upward.

[0034] This design is for reference. Figure 4 The refrigerant discharged from the outlet 32 ​​extends to the corresponding height of the freezer rack body 4, precisely replenishing the freezer rack body 4 with cold air.

[0035] In one or more embodiments, the mounting component 2 is a plurality of mounting blocks 7, the mounting blocks 7 being glued between two cryopreservation rack bodies 4, and the partition body 1 being inserted into the mounting blocks 7.

[0036] This design is for reference. Figure 1-2 The mounting component 2 can be installed on the shell of the refrigerator body 5 or on the freezer rack body 4, as long as the partition body 1 is placed between the two freezer rack bodies 4.

[0037] In one or more embodiments, a collection box 9 is further included, which is located on the cryopreservation rack body 4 corresponding to the bottom end of the sample plate. The opening of the collection box 9 faces upward and is used to collect liquid refrigerant. The cryopreservation rack body 4 is provided with a drain port 10 that communicates with the collection box 9.

[0038] This design is for reference. Figure 6 The collection box 9 is specifically for use when the refrigerant is liquid. The refrigerant discharged from the outlet 32 ​​will be collected in the corresponding collection box 9. The drain port 10 is connected to an external pipe, and the refrigerant in the collection box 9 will be discharged from the storage chamber through the pipe.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

[0040] It should be noted that if the utility model embodiment involves directional indicators (such as up and down), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0041] Furthermore, the meaning of "and / or" throughout the text includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or a solution that simultaneously satisfies A and B. Additionally, if the utility model embodiments involve descriptions such as "first," "second," etc., these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" can explicitly or implicitly include at least one of those features. Furthermore, "multiple" refers to two or more.

[0042] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of a person skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection of the utility model.
