Description

Technical Field

[0001] This utility model relates to the field of air-cooling device technology, specifically to a sample inlet air-cooling structure. Background Technology

[0002] In the field of biological sample storage, many samples need to be stored at low temperatures in automated individual cryopreservation boxes. In the existing technology, the cryopreservation boxes to be stored at low temperatures need to first be placed in the sample loading and unloading chamber at -20°C, and then sent into the low temperature cryopreservation chamber at -80°C after being arranged by mechanical grippers to complete the storage.

[0003] Currently, to avoid the problem of excessive temperature fluctuations caused by the loss of cooling atmosphere due to repeated opening of automated single-unit cryopreservation boxes, most designs use multi-layer sample racks to achieve the function of injecting multiple cryopreservation boxes at a time. However, after the multiple cryopreservation boxes are injected, they still need to be arranged in sequence by mechanical grippers, which indirectly prolongs the time period for the lower cryopreservation boxes to enter the low-temperature cryopreservation chamber for freezing. At the same time, the sample inlet of the sample loading and unloading chamber inevitably loses cooling atmosphere during the injection process, causing the temperature to rise and the temperature near the sample inlet to be higher than -20°C. The multi-layer cryopreservation box cannot quickly obtain good temperature conditions.

[0004] Therefore, it is necessary to provide a rapid cold atmosphere to the cryopreservation box after sample injection and to apply low temperature treatment to the cryopreservation box to avoid damaging some of the samples to be frozen during a long conditioning process; in view of this, we propose a sample injection air-cooling structure.

[0015] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] Please see Figures 1-5 The present invention will describe the above technical solution in detail through the following embodiments: The sample inlet air-cooling structure of this embodiment includes a fixed plate 1 that is vertically installed at the sample inlet of the sample loading and unloading chamber of the automated single cryopreservation box. A horizontally set slide rail 3 is installed on the fixed plate 1. This part belongs to the existing sample inlet structure and is intended to realize the inlet and outlet movement at the sample inlet to facilitate the storage and retrieval of the cryopreservation box.

[0017] Specifically, such as Figure 4 , Figure 5 As shown, the sample feeder assembly 7 includes a vertical plate 72 with a support plate 71 fixedly mounted on its inner side. A drive motor 2 is mounted on the support plate 71 as a power source. In order to realize automated feeding and discharging actions, a slider 5 for sliding on a slide rail 3 is fixedly mounted on the back of the support plate 71. At the same time, a rack plate 4 is mounted on the fixed plate 1. A gear 6 that meshes with the rack plate 4 is mounted coaxially on the output shaft of the drive motor 2. The drive motor 2 drives the gear 6 to reciprocate, thereby driving the entire sample feeder assembly 7 to reciprocate along the rack plate 4 to complete the feeding and discharging actions.

[0018] like Figures 1-2 As shown in the structure, in this embodiment, for ease of assembly and disassembly, two side clamps 73 are vertically and symmetrically installed on the vertical plate 72, and a five-layer support unit 8 can be detachably installed between the two side clamps 73.

[0019] like Figure 3The structure shown includes a support unit 8 with a support plate 81 having a groove 811 for supporting the cryopreservation box 10, and a ventilation slot 812 inside the groove 811. A base frame 9 is detachably mounted on the bottom of the side clamp 73, and a second fan 11 corresponding to the position of the ventilation slot 812 is detachably mounted on the base frame 9. The second fan 11 blows air upwards, allowing cold air to flow vertically through the ventilation slot 812. To improve cold storage capacity, cold storage fins 83 are installed inside the ventilation slot 812. The fins of the cold storage fins 83 are perpendicular to the surfaces of the support plate 81 and the vertical plate 72 to facilitate cold air circulation. In this embodiment, the cold storage fins 83 have shafts 831 at both ends, and the ventilation slot 812 has slots 813 for mounting the shafts 831. Infrared sensors 82 are installed diagonally on the groove 811 to monitor the presence of the cryopreservation box 10.

[0020] In this embodiment, five first fans 74 are provided on the vertical plate 72, each corresponding to one of the five cryogenic boxes 10. The first fans 74 are driven by the power supply to blow air towards the cryogenic boxes 10. Together with the second fans 11 blowing air upward in the vertical direction, cold air is directionally flowed through the cryogenic boxes 10 in a ring, avoiding local temperature dead zones. This allows the low-temperature cold air inside to continuously flow and contact the surface of the cryogenic boxes 10, avoiding local cooling delays and accelerating the heat dissipation rate of the surface of the cryogenic boxes 10. This greatly improves the efficiency of heat removal and enables rapid cooling through convection heat transfer.

[0021] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0022] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
