The placement of the driving device inside the refrigeration and freezing device 10 for storing biological samples such as an automated refrigerator and a freezer is always a relatively headache problem, if the driving device is directly placed inside the refrigeration and freezing device 10, because the ultra-low temperature (-80 ℃) inside the driving device is far lower than the use environment of the driving device such as a motor, only special low-temperature resistant components can be selected under the condition, the cost of the components is usually quite high, the competitiveness of the whole machine is directly affected, and in addition, the ultra-low temperature environment has a great number of risks which are difficult to estimate for the normal operation of the driving device.
In this embodiment, a brand new design is performed on the case 100, where the case 100 is divided into two open spaces, and when the upper space is operated, the temperature is maintained at about-40 ℃ (for example only, and can be determined according to practical situations), and the temperature of the lower space is maintained at about-80 ℃ (for example only, and can be determined according to practical situations). The drive device is placed in the upper high temperature zone, which is also relatively friendly to the operation of the drive device and also provides reliability of the operation of the whole set of the mechanism.

In some embodiments, the portion of the case 100 that forms the storage area 111, and the portion of the case 100 that forms the equipment area 112 may be made of sheet metal, and the separator may be plastic (e.g., a ring of plastic), and in other embodiments, may be made of other materials.
The separator includes at least: a first partition extending in a first direction; a second partition extending in a second direction different from the first direction; and the connecting part is used for connecting the first separation part and the second separation part. Thus, such a partition can adapt to complex housing cavity shapes.
Specifically, the connection portion is provided with one of a plugging projection and a slot, and the first partition portion and the second partition portion are provided with the other of the plugging projection and the slot.

Thus, the cold amount is more entered into the storage area 111, facilitating the storage of the biological sample and avoiding the interference to the driving apparatus.
Wherein the at least part of the evaporator 200 located inside the mounting case is located at a side of the inside of the mounting case near the storage area 111, and the temperature shut-off device 120 comprises: and a heat insulating member disposed at one side of the inside of the installation box, which is close to the equipment area 112, to reduce the transfer of the cold generated by the evaporator 200, which is located inside the installation box, to the equipment area 112. Specifically, the heat insulating member may be made of a foaming, foam, or the like material. Thereby, it is further ensured that more cold enters the storage area 111, facilitating the storage of the biological sample and avoiding the interference to the driving device.
Wherein, the at least one mounting box is a plurality of mounting boxes that the interval set up, thereby, not only guaranteed that the cold volume gets into storage area 111 more, still provided the removal space of getting and putting the device.
In some embodiments, the refrigeration and freezer 10 can further include: the compressor is mounted on the first side of the box 100 and is located outside the accommodating cavity, and is configured to form a refrigeration system together with the evaporator 200 (it will be understood that the whole refrigeration system may also include other devices such as a throttling device and a condenser, and the refrigeration system of this embodiment may be a dual-cascade refrigeration system, and this embodiment may have two sets of dual-cascade refrigeration systems). And the plurality of mounting boxes comprises: a first mounting box disposed in a region of the thermal insulation region 113 corresponding to the first side; a second mounting box disposed in a region of the thermal insulation region 113 corresponding to a second side opposite to the first side; and the evaporator 200 is configured to enter the second mounting box first and then enter the first mounting box to be connected with the compressor.

Therefore, the taking and placing device can be installed through the gap between the third installation box and the second installation box, the installation is convenient, and the installation efficiency is improved.
In some embodiments, the equipment area 112 is located above the storage area 111, so that the effect of cold air sedimentation on the temperature of the mechanism placement area is reduced, air in the box naturally convects when in operation, and cold air sedimentation hot air rises, and two temperature spaces are layered up and down by taking the heat insulation area 113 as a boundary. In this embodiment, the special heat insulation area 113 is designed to cut off the heat conduction between the storage area metal plate and the mechanism area metal plate, and then the refrigeration pipelines are all arranged in the storage area 111, so that two temperature areas, namely an upper-40 ℃ area and a lower-80 ℃ area, are generated under the condition of natural convection in the box.
