DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0029] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings).

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0031] See also Figures 1 to 3 In some optional embodiments, the present application provides a refrigerated storage device, comprising a rack 1 and at least two refrigeration devices 2. In addition to the above components, the refrigerated storage device may also include a turbulent fan 3. The rack 1 is provided with a storage area, which can be used to store items, such as a sample tray 5. The sample tray 5 can hold sample tubes containing samples that need to be refrigerated. The refrigeration device 2 is installed on the rack 1. The refrigeration device 2 includes a refrigerator 201, an air outlet duct 202, and a return air duct 203. The air inlet end of the air outlet duct 202 is connected to the air outlet 2011 of the refrigerator 201, and the air outlet end of the air outlet duct 202 is located above the storage area. The air inlet end of the return air duct 203 is located below the storage area, and the air outlet end of the return air duct 203 is connected to the return air outlet 2012 of the refrigerator 201. The cold air generated by the refrigerator 201 is discharged from the air outlet 2011 and enters the air outlet duct 202. The cold air is discharged from the air outlet end of the air outlet duct 202, gradually sinks, passes through the storage area, enters from the air inlet end of the return air duct 203, and is discharged from the return air outlet 2012 back to the refrigerator 201 for the next cycle; among them, due to the high density of the cold air, the cold air will naturally move downward, the air outlet end of the air outlet duct 202 is located above the storage area, and the air inlet end of the return air duct 203 is located below the storage area. The cold air needs to flow through the storage area before it can be discharged from the air inlet end of the return air duct 203, which is conducive to the cold air fully acting on the storage area and improving the cooling effect; under the action of the refrigerator 201, the return air outlet 2012 has suction, so that the cold air can smoothly flow to the return air outlet 2012 and be discharged from the return air outlet 2012 after sinking to the bottom of the storage area.

[0032] Optionally, a turbulence fan 3 is mounted on the rack 1 near the end of the air outlet of the air outlet duct 202. The turbulence fan 3 is helpful in increasing the flow velocity of the airflow, thereby accelerating the circulation of the airflow; in particular, the airflow at the end of the air outlet is slower than the airflow at the beginning of the air outlet, and the turbulence fan 3 increases the flow velocity of the airflow at the end of the air outlet, which is helpful in improving the cooling efficiency, thereby helping to ensure the cooling effect.

[0033] Optionally, there are two sets of refrigeration units 2, and the air outlet ducts 202 of the two sets of refrigeration units 2 are symmetrically distributed in the horizontal direction. The turbulence fan 3 is located between the two air outlet ducts 202, and the turbulence fan 3 is located above the air outlet duct 202, which helps to accelerate the downward flow of cold air. Furthermore, the air inlet ends of the two air outlet ducts 202 are connected, and the two air outlet ducts 202 are connected to form a U-shaped structure. The two air outlet ducts 202 are connected, so that the cold air discharged from one refrigerator 201 can be evenly discharged through the two air outlet ducts 202, which helps to improve the uniformity of the cold air distribution. It is understandable that the air inlet ends of the two air outlet ducts 202 can also be blocked and not connected. In addition, the two sets of refrigeration devices 2 can operate synchronously or one can be used as a backup; specifically, in the normal working mode: the two sets of refrigeration devices 2 work alternately to ensure that the temperature controls the target temperature threshold. The target temperature threshold can be set according to demand. For example, the target temperature threshold is 2-8°C. When the storage area temperature is higher than 8°C, the two sets of refrigeration devices 2 work simultaneously to reduce the temperature to the target temperature at the maximum speed, and then the two sets of refrigeration devices 2 stop working. In this mode, the temperature reduction speed is fast and the cooling efficiency is high; or, when the storage area temperature is higher than 8°C, only one set of refrigeration device 2 is started at this time. The two sets of refrigeration devices 2 can be started alternately. When the temperature reaches the target temperature again, the refrigeration device 2 stops working. This mode can ensure that the temperature is controllable while reducing energy consumption and increasing the service life of the equipment. At the same time, if one of the refrigeration devices 2 fails, the other set of refrigeration device 2 can still continue to be used, and there is no need to frequently take and put samples in the storage area while waiting for maintenance.

[0034] In the refrigeration storage equipment of the above embodiment, the refrigerator 201, the air outlet duct 202 and the return air duct 203 of the refrigeration device 2 are integrated together, which can reduce the difficulty of on-site installation and debugging. The air outlet duct 202 and the return air duct 203 are directly connected to the air outlet 2011 and the return air outlet 2012 of the refrigerator 201, thereby reducing the number of additional external pipes, reducing the risk of leakage of the external pipes, and improving the reliability of the refrigeration device 2; and at least two sets of refrigeration devices 2 are provided, and the number of operating refrigeration devices 2 can be flexibly selected according to demand. Even if one of the refrigeration devices 2 fails, there is a spare refrigeration device 2, which avoids the complete paralysis of the refrigeration storage equipment and improves the reliability of the refrigeration storage equipment.

[0035] See also Figures 1 to 4and Figure 6 In some optional embodiments, the storage area is installed with multiple layers of storage racks 101 distributed in the vertical direction, and each layer of storage racks 101 is provided with multiple storage positions 1011 distributed along the extension direction of the air outlet end of the air outlet duct 202, and an air outlet structure is provided on the air outlet end of the air outlet duct 202.

[0036] Optionally, two air outlet ducts 202 are arranged side by side in the horizontal direction, and multiple storage positions 1011 can be arranged in two rows along the side-by-side direction of the air outlet ducts 202. Each air outlet duct 202 corresponds to a row of storage positions 1011, with a compact layout and uniform cooling.

[0037] Optionally, multiple groups of air outlet structures are provided between the head end and the tail end of the air outlet end of the air outlet duct 202, and the multiple groups of air outlet structures are evenly distributed along the extension direction of the air outlet end of the air outlet duct 202. Furthermore, the multiple groups of air outlet structures are arranged in a one-to-one correspondence with the multiple storage locations 1011 located on the top layer, and the vertical projections of the storage locations 1011 located on the top layer coincide with the vertical projections of the storage locations 1011 located on the lower layer. In other words, the storage locations 1011 on each layer are aligned in the vertical direction, so that the cold air discharged by the corresponding air outlet structures can gradually sink from top to bottom and act on the storage locations 1011 on each layer, so that the samples stored in the storage locations 1011 on each layer can be evenly cooled.

[0038] Optionally, each set of air outlet structures includes two oppositely arranged air outlet holes 2021, and the air outlet holes 2021 discharge air in a horizontal direction. The air outlet holes 2021 are arranged in a horizontal direction to prevent the cold air discharged from the air outlet holes 2021 from directly acting on the storage position 1011 below the air outlet holes 2021, which can effectively prevent local low temperatures. The cold air discharged horizontally from the air outlet holes 2021 naturally sinks, which facilitates the cold air to be evenly dispersed and applied to the storage position 1011, thereby improving cooling uniformity.

[0039] In the refrigeration storage device of the above embodiment, the cold air discharged by the air outlet structure can act on multiple storage positions 1011, and the structure layout is compact, which not only improves the space utilization of the storage area, but also ensures the cooling effect.

[0040] See also Figure 1 、 Figure 2 、 Figure 4 and Figure 5 In some optional embodiments, an air regulating port is provided at the end of the air outlet end of the air outlet duct 202, and an adjusting baffle 4 is installed at the air regulating port. The adjusting baffle 4 is movably installed on the air outlet duct 202 and adjusts the air volume of the air regulating port.

[0041] Optionally, the adjustment baffle 4 is locked and connected to the air outlet duct 202 through a locking member 402, and the locking member 402 can be a bolt. Furthermore, a strip hole 401 is provided on the adjustment baffle 4, and the locking member 402 passes through the strip hole 401 to connect the adjustment baffle 4 to the air outlet duct 202. The locking member 402 is loosened, and the adjustment baffle 4 is moved so that the adjustment baffle 4 moves along the length direction of the strip hole 401, and the range of the adjustment baffle 4 covering the air adjustment port is adjusted. When it is adjusted to a suitable range, the locking member 402 is tightened so that the adjustment baffle 4 is locked and fixed to the air outlet duct 202. Among them, the adjustment baffle 4 can completely cover the air adjustment port, or it can completely expose the air adjustment port; when the air adjustment port is completely covered, the air output of the air outlet 2021 can reach the maximum, and when the air adjustment port is completely exposed, the air output of the air outlet 2021 is reduced to the minimum.

[0042] The refrigeration storage device of the above embodiment controls the air volume of the air regulating port by adjusting the baffle 4 to adjust the air volume of the air outlet 2021 located above the storage position 1011, so as to adjust the cooling temperature. The adjustment is simple, convenient and flexible.

[0043] See also Figures 1 to 6 In some optional embodiments, the present application further provides a sample analysis pipeline, comprising a sample injection device, a sample transport device, a sample pre-processing device, a sample analysis device, and a sample post-processing device; the sample transport device transports the sample from the sample injection device to the sample pre-processing device for pre-processing, and then the sample enters the sample analysis device for analysis; after the sample is analyzed, it is transported to the sample post-processing device via the sample transport device;

[0044] The sample post-processing equipment includes a refrigerated storage device and an interface device as described in any of the above embodiments. The refrigerated storage device is used to refrigerate samples. The interface device has a buffer zone, which includes the refrigerated storage device for placing samples and a placement station for refrigerated storage racks. The refrigerated storage device also has a transfer assembly for transferring refrigerated racks from the buffer zone to a storage area for refrigeration. This sample analysis pipeline provides a stable temperature storage environment for samples during transfer, ensuring uniform cooling and stable performance, facilitating low-temperature sample storage and facilitating automated operations.

[0045] The refrigeration storage equipment and sample analysis pipeline of the present invention cooperate with each other through at least two sets of refrigeration devices 2 to ensure that the refrigeration storage equipment can maintain normal operation continuously and stably, thereby improving the cooling effect and reliability of the refrigeration storage equipment; and the refrigerator 201, the air outlet duct 202 and the return air duct 203 are integrated together, which reduces the difficulty of subsequent on-site assembly, makes maintenance and installation simpler and more convenient, and reduces maintenance costs.
