[0030] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0031] Referring to Figures 1 to 3, Figure 1 shows a simplified schematic diagram of a material refrigeration storage device according to an embodiment of the present application. Figures 2 and 3 show schematic diagrams of the arrangement of the first air inlet 102 and the first air outlet 103 on the bottom wall of the storage chamber 101 according to two different embodiments of the present application. An embodiment of the present application provides a material refrigeration storage device, which includes a storage shell 10 and a refrigeration module 20. The storage shell 10 includes but is not limited to various devices having a storage chamber 101, such as a cabin, a pot, a container, and a box. The storage shell 10 is provided with a storage chamber 101 and a first air inlet 102 and a first air outlet 103 in communication with the storage chamber 101. The refrigeration module 20 is detachably arranged on the outside of the storage shell 10. The refrigeration module 20 is provided with a cold air outlet 21, which is in communication with the first air inlet 102.

[0032] In the above-mentioned material refrigeration storage device, the refrigeration module 20 is detachably connected to the outside of the storage shell 10, so that it can be completely separated from the storage shell 10. The refrigeration module 20 is no longer placed inside the storage shell 10, which can improve the maintainability of the refrigeration module 20, shorten the maintenance time as much as possible, and improve maintenance efficiency. In addition, the purpose of cooling the storage chamber 101 is achieved by sending cold air, which is conducive to improving the refrigeration uniformity of the storage chamber 101 and avoiding the defects such as temperature unevenness and condensation water caused by the use of solid refrigeration or water cooling in the storage chamber 101 in the related art. In addition, the cold air from the cold air outlet 21 enters the interior of the storage chamber 101 through the first air inlet 102 and is discharged to the outside through the first air outlet 103.

[0033] Referring to Figures 1 to 3, in one embodiment, an air duct 1011 is formed in the storage chamber 101. The air duct 1011 is connected to the first air inlet 102 and the first air outlet 103, respectively. In this way, the air duct 1011 forms a reasonable wind field in the storage chamber 101, thereby achieving the purpose of uniform temperature in the storage chamber 101. Specifically, during operation, the air duct 1011 guides the cold air entering from the first air inlet 102 and discharges it outward through the first air outlet 103. In addition, as the cold air flows along the air duct 1011, it cools various parts of the air duct 1011, resulting in good cooling uniformity.

[0034] The shape of the air duct 1011 can be configured in accordance with the specific shape of the storage chamber 101 to ensure that the cold air flows as uniformly as possible throughout the storage chamber 101, thereby improving cooling uniformity. In some embodiments, the shape of the air duct 1011 includes, but is not limited to, regular shapes such as straight lines and curves, as well as irregular shapes. Curves include, but are not limited to, various shapes such as annular, S-shaped, Z-shaped, and L-shaped.

[0035] Please refer to Figures 4 to 6. Figure 4 shows a schematic diagram of the exploded structure of a material refrigeration storage device according to an embodiment of the present application. Figures 5 and 6 respectively show two structural diagrams of the storage shell 10 in the structure shown in Figure 4 from different perspectives. In some embodiments, the storage shell 10 is provided with an openable cover, which is not shown in Figures 4 to 6. When the cover is opened, materials can be installed inside the storage shell 10 and removed from the storage shell 10. In addition, a mounting rack for installing materials is provided inside the storage shell 10, which is not shown in Figures 4 to 6. The mounting rack includes but is not limited to a reagent tray, etc. In addition, insulation components such as insulation cotton are wrapped around the outer wall of the storage shell 10, which is not shown in Figures 4 to 6. The insulation cotton plays a role in insulation, which is beneficial to the cooling effect and constant temperature of the storage chamber 101. In addition, the storage shell 10 can also be provided with parts with various other functions according to actual needs.

[0036] Please refer to Figures 2 and 3. In one embodiment, the storage housing 10 includes an annular air guide 104 connected to the bottom wall of the storage chamber 101. The air guide 104 is not shown in Figures 4 to 6. The air guide 104 cooperates with the side wall of the storage chamber 101 to form an annular air duct 1011. The air duct 1011 can be specifically configured to have regular shapes such as a circular ring, an elliptical ring, a polygonal ring, and other irregular shapes. In this way, when the cold air entering from the first air inlet 102 flows along the annular air duct 1011, it has a more uniform cooling effect on the storage chamber 101.

[0037] In some embodiments, the air guide member 104 can be flexibly adjusted and configured according to actual needs, including but not limited to being configured as various structural forms such as an air guide plate and an air guide block.

[0038] It should be noted that the "air guide member 104" can be "a part of the bottom wall of the storage chamber 101", that is, the "air guide member 104" and the "other parts of the bottom wall of the storage chamber 101" are manufactured as one piece; it can also be an independent component that can be separated from the "other parts of the bottom wall of the storage chamber 101", that is, the "air guide member 104" can be manufactured independently and then combined with the "other parts of the bottom wall of the storage chamber 101" into a whole.

[0039] Referring to FIG. 2 , in some embodiments, the first air inlet 102 and the first air outlet 103 are disposed on opposite sides of the air duct 1011. Thus, the first air inlet 102 and the first air outlet 103 are relatively far apart, specifically, for example, at the two farthest endpoints of the air duct 1011. When the first air inlet 102 and the air outlet are at their farthest distance, the wind field and temperature field formed within the storage chamber 101 are relatively balanced.

[0040] Referring to FIG. 3 , in some embodiments, the first air inlet 102 and the first air outlet 103 may be arranged at two adjacent locations in the air duct 1011, with the openings of the first air inlet 102 and the first air outlet 103 facing opposite directions, that is, the first air inlet 102 and the first air outlet 103 are arranged back to back. In this way, the cold air from the first air inlet 102 travels around the air duct 1011 and then returns to the first air outlet 103 for discharge. In this way, the storage chamber 101 and the refrigeration module are connected by a pipe, the diameter of which is, for example, 70 mm. When the first air inlet 102 and the air outlet are arranged adjacent to each other, the length of the pipe can be minimized, which helps to reduce the space occupied at the bottom of the storage housing 10 and reduces the amount of cooling loss through the pipe.

[0041] Referring to Figures 4 to 6, in one embodiment, the storage shell 10 is provided with an air inlet nozzle 105 and an air exhaust nozzle 106. The first air inlet 102 is provided on the air inlet nozzle 105, and the first air exhaust nozzle 103 is provided on the air exhaust nozzle 106. The air inlet nozzle 105 and the air exhaust nozzle 106 pass through the storage shell 10 and extend to the outside of the storage shell 10. The air inlet nozzle 105 is connected to the cold air outlet portion 21. The refrigeration module 20 is provided with a return air portion 22, and the return air portion 22 is connected to the air exhaust nozzle 106. In this way, under the action of the air inlet nozzle 105 and the air exhaust nozzle 106, it is convenient to realize the introduction of cold air into the air duct 1011 and circulate in the air duct 1011 to improve the uniformity of cooling. In addition, the air inlet nozzle 105 and the air exhaust nozzle 106 can be easily assembled and connected with the refrigeration module 20.

[0042] In addition, when the first air inlet 102 and the first air outlet 103 are respectively arranged at two adjacent positions of the air duct 1011, and the openings of the first air inlet 102 and the first air outlet 103 are facing opposite directions, the air inlet nozzle 105 and the air outlet nozzle 106 are arranged back to back.

[0043] In some embodiments, the air inlet nozzle 105 and the air outlet nozzle 106 are specifically provided on the bottom wall or side wall of the storage housing 10. This embodiment will be described with the air inlet nozzle 105 and the air outlet nozzle 106 provided on the bottom wall of the storage chamber 101 as an example.

[0044] Please refer to Figures 4 to 7. Figure 7 shows a simplified cross-sectional view of the bottom wall of the storage shell 10 according to an embodiment of the present application. In one embodiment, the bottom wall surface of the storage chamber 101 is arranged in a curved shape. The first air inlet 102 is arranged at a lower position on the bottom wall. In this way, the cold air entering through the first air inlet 102 will flow along the curved bottom wall from a lower position on the bottom wall, and the bottom wall will play a role in disturbing and guiding the cold air. The high and low design of the bottom wall is more conducive to the formation of a circular circulating wind field for the cold air in the storage cabin. The circulating wind field makes the temperature of each temperature point in the storage cabin uniform, effectively lowering the temperature of the storage chamber 101 while reducing the temperature difference in the cabin, thereby reducing the formation of condensed water.

[0045] It should be noted that the portion with a lower height refers to the portion on the bottom wall that is closer to the work surface when the material refrigeration storage device is placed on the work surface, with the work surface as a reference surface; conversely, the portion with a higher height refers to the portion on the bottom wall that is farther away from the work surface.

[0046] In some embodiments, the lower portion and the higher portion of the bottom wall are distributed on opposite sides of the storage chamber 101 .

[0047] Referring to Figures 4 to 6 , in some embodiments, when the first air outlet 103 is adjacent to and back-to-back with the first air inlet 102, the first air outlet 103 is also, for example, arranged at a lower portion of the bottom wall, that is, arranged at the same time as the first air inlet 102 on the lower surface 1012 of the bottom wall. Of course, the first air outlet 103 may also be arranged at a higher portion of the bottom wall, that is, arranged on the higher surface 1013 of the bottom wall, which is not illustrated in the figures.

[0048] 5 to 7 , in one embodiment, the bottom wall of the storage chamber 101 includes a lower surface 1012, a higher surface 1013, and a transition surface 1014 connecting the lower surface 1012 and the higher surface 1013. The transition surface 1014 includes at least one of a flat surface and a curved surface, or a combination thereof.

[0049] Please refer to FIG. 5 to FIG. 7 , wherein the curved surface includes but is not limited to various regular shapes such as arc shape, parabola shape, broken line shape and other irregular shapes.

[0050] 5 to 7 , in one embodiment, the distance H between the lower surface 1012 and the upper surface 1013 is not less than 25 mm. Thus, a larger distance H between the lower surface 1012 and the upper surface 1013 is more conducive to enhancing the turbulence effect and the cooling effect.

[0051] Referring to Figures 4, 6, and 8, in one embodiment, the cold air outlet portion 21 is provided with a cold air outlet duct. This duct is not shown in Figures 4 and 8. The cold air outlet duct is removably connected to the storage housing 10. Specifically, the cold air outlet duct is removably connected to the air inlet nozzle 105, for example. In this way, the cold air from the cold air outlet portion 21 is output through the cold air outlet duct to the air inlet nozzle 105, and then input into the storage chamber 101 by the air inlet nozzle 105. Of course, the air inlet nozzle 105 can be omitted. If so, the cold air outlet duct will directly connect to the first air inlet 102.

[0052] Please refer to Figures 4, 6 and 8. In one embodiment, the refrigeration module 20 is further provided with a return air portion 22 connected to the first air outlet 103. The return air portion 22 is provided with a return air duct, which is not shown in Figures 4 and 8. The return air duct is detachably connected to the storage shell 10. Specifically, the return air duct is detachably connected to the exhaust nozzle 106. In this way, the air inside the storage shell 10 flows back to the refrigeration module 20 through the first air outlet 103 and the return air duct. Similarly, the exhaust nozzle 106 can be omitted. When the exhaust nozzle 106 is omitted, the return air duct will be directly connected to the first air outlet 103.

[0053] Among them, when the cold air outlet duct is detachably connected to the air inlet nozzle 105, and the return air duct is detachably connected to the exhaust nozzle 106, the refrigeration module 20 is detachably connected to the outside of the storage shell 10, so that it can be completely separated from the storage shell 10. The refrigeration module 20 is no longer placed inside the storage shell 10, which can improve the maintainability of the refrigeration module 20, shorten the maintenance time as much as possible, and improve the maintenance efficiency.

[0054] Please refer to Figures 4, 6 and 8. In some embodiments, the cold air outlet duct and the return air duct are independently set, including but not limited to being set as a corrugated pipe, and for example, the outer walls of each duct are wrapped with insulation components such as insulation cotton of sufficient thickness.

[0055] Please refer to Figures 4, 6 and 8. In one embodiment, the cold air outlet 21 is provided with at least one first power source 23 for driving the air to be discharged outward into the storage chamber 101. In addition, the return air portion 22 is provided with at least one second power source 24 for driving the air to flow back into the refrigeration module 20. In this way, driven by the power provided by the first power source 23 and / or the second power source 24, the cold air circulates in the annular wind flow field formed by the combination of the refrigeration module 20 and the storage chamber 101, thereby having a better cooling effect on the storage chamber 101. In addition, by using the air supply method, the refrigeration module 20 is moved to the outside of the storage shell 10, thereby improving the maintainability and maintenance efficiency of the refrigeration module 20.

[0056] Please refer to Figures 4, 6 and 8. In some embodiments, the first power source 23 and the second power source 24 are independently configured, including but not limited to various power mechanisms such as fans and power pumps, as long as they can provide power to drive the cold air to flow into the storage chamber 101 and drive the air in the storage chamber 101 to flow back to the refrigeration module 20.

[0057] Please refer to Figures 4, 6 and 8. In some embodiments, the respective working powers of the first power source 23 and the second power source 24 are adjustable, so that the volume and speed of the cold air entering the storage chamber 101 can be flexibly adjusted and set according to actual needs. Specifically, according to the ambient temperature inside the storage chamber 101 and the cold air temperature of the refrigeration module 20, the working powers of the first power source 23 and the second power source 24 are adjusted accordingly to adjust the volume and speed of the cold air entering the storage chamber 101, so as to maintain the temperature of the internal environment of the storage chamber 101 within a preset range. In addition, the working powers of the first power source 23 and the second power source 24 can be flexibly adjusted according to different use stages, different use modes or different use scenarios of the material refrigeration storage device, so that the ambient temperature inside the storage chamber 101 meets the preset requirements. For example, when the material refrigeration storage device is in the initial stage of being put into use, in order to quickly reduce the ambient temperature inside the storage chamber 101 to a preset temperature, the first power source 23 and the second power source 24 are operated at a higher working power; when the internal ambient temperature of the material refrigeration storage device reaches the preset temperature and is in a constant temperature stage, the first power source 23 and the second power source 24 are operated at a lower working power, or the first power source 23 and the second power source 24 are each operated, for example, intermittently; when the material refrigeration storage device is in the state of opening the cover to take out materials from the storage chamber 101 or put in new materials or performing maintenance, in order to maintain a constant temperature inside the storage chamber 101, the first power source 23 and the second power source 24 are operated at a higher working power.

[0058] Please refer to FIG. 4 , FIG. 6 and FIG. 8 . In one embodiment, the first power source 23 and the second power source 24 are both configured as fans with adjustable wind speeds, so as to flexibly adjust the wind field in the storage chamber 101 .

[0059] Referring to Figures 4, 6, and 8, in one embodiment, the refrigeration module 20 is provided with a refrigeration terminal 25, which is located between the return air section 22 and the cold air outlet 21. The return air from the return air section 22 is cooled by the refrigeration terminal 25 and then output to the cold air outlet 21. The material refrigeration storage device also includes a controller (not shown in the figure), a first temperature sensor (not shown in the figure) for sensing the internal environment of the storage chamber 101, and a second temperature sensor (not shown in the figure) for sensing the refrigeration terminal 25 or the cold air outlet 21. Specifically, the controller is electrically connected to the first temperature sensor, the second temperature sensor, the first power source 23, the second power source 24, and the refrigeration module 20, respectively. Thus, based on the temperatures sensed by the first temperature sensor and the second temperature sensor, under the control of the controller, the first power source 23, the second power source 24, and the refrigeration module 20 coordinate and operate to control the temperature of the internal environment of the storage chamber 101 within a preset range.

[0060] In addition, when the second temperature sensor senses that the temperature of the cooling end 25 or the cold air outlet 21 exceeds the threshold temperature, for example, higher than 1.5°C or lower than 1.5°C, the controller accordingly controls the cooling module 20 to increase or reduce the working power; conversely, when the second temperature sensor senses that the temperature of the cooling end 25 or the cold air outlet 21 is the threshold temperature, the controller accordingly controls the cooling module 20 to maintain the current working power and continue to operate.

[0061] Among them, the preset temperature and threshold temperature in the above embodiments are flexibly adjusted and set according to actual needs and are not limited here.

[0062] In some embodiments, when the second temperature sensor senses that the cold air temperature at the cooling end 25 or the cold air outlet 21 is higher than the threshold temperature, the controller accordingly controls the cooling module 20 to increase the working power, and at the same time makes the first power source 23 and the second power source 24 each work at a higher working power, for example, the fan speed is adjusted to the maximum gear; conversely, when the second temperature sensor senses that the cold air temperature at the cooling end 25 or the cold air outlet 21 is lower than the threshold temperature, the controller accordingly controls the cooling module 20 to reduce the working power, and at the same time makes the first power source 23 and the second power source 24 each work at a lower working power, for example, the fan speed is reduced.

[0063] In some embodiments, when the second temperature sensor senses that the cold air temperature at the cooling end 25 or the cold air outlet 21 is at a threshold temperature, the cooling module 20 maintains its current operating power. Furthermore, the first temperature sensor senses the temperature of the storage chamber 101, and controls the operation of the first power source 23 and the second power source 24 accordingly based on the temperature sensed by the first temperature sensor.

[0064] Referring to Figures 4, 6, and 8, in one embodiment, the cooling module 20 further comprises a heat sink 26, and a second air inlet 27 and a second air outlet 28, each of which is in communication with the heat sink 26. Thus, outside air enters the heat sink 26 through the second air inlet 27, removes heat from the heat sink 26, and is then discharged through the second air outlet 28. The heat sink 26 dissipates heat into the environment, thereby lowering the temperature of the cooling end 25.

[0065] Referring to Figures 4, 6, and 8, in one embodiment, at least one third power source 291 is provided at the second air inlet 27 to drive air to the heat sink 26. Furthermore, at least one fourth power source 292 is provided at the second air outlet 28 to drive the hot air outward. Thus, driven by the power provided by the third power source 291 and / or the fourth power source 292, ambient air flows sequentially through the second air inlet 27, the heat sink 26, and the second air outlet, achieving a good heat dissipation effect on the heat sink 26.

[0066] In some embodiments, the third power source 291 and the fourth power source 292 are independently configured, including but not limited to various power mechanisms such as fans and power pumps.

[0067] In some embodiments, the operating power of the third power source 291 and the fourth power source 292 is adjustable, allowing the air volume and speed entering the heat sink 26 to be flexibly adjusted and configured according to actual needs. Specifically, when the temperature of the cooling end 25 needs to be lowered, the operating power of the third power source 291 and the fourth power source 292 is increased accordingly, which can quickly dissipate the large amount of heat generated at the heat sink 26, thereby effectively lowering the temperature of the cooling end 25.

[0068] In a specific embodiment, the third power source 291 and the fourth power source 292 are both configured as fans with adjustable wind speeds.

[0069] In some embodiments, the cooling module 20 includes, but is not limited to, a TEC, a refrigeration unit with an air compressor, or other refrigeration devices. Using a refrigeration unit with an air compressor can improve cooling power, while using a TEC can simplify the structure, reduce size, and lower costs. This embodiment uses TEC cooling as an example, but this is not limiting.

[0070] Referring to Figures 4, 6, and 8, in one embodiment, a first heat sink 251 is provided on the cooling end 25. Furthermore, a second heat sink 261 is provided on the heat dissipation end 26. Specifically, the first heat sink 251 and the second heat sink 261 are independently configured and may include, but are not limited to, at least one of heat sinks, heat pipes, and homogeneous heat sinks, or a combination thereof. This facilitates improved cooling and heat dissipation through the heat dissipation provided by the first and second heat sinks 251, 261.

[0071] Among them, when the first radiator 251 and the second radiator 261 are each configured as a homogeneous radiator, also called a 3DVC radiator, with the cooling end 25 facing downward and the heat dissipation end 26 facing upward, the heat dissipation efficiency of the radiator can be greatly improved, further improving the cooling efficiency of the TEC.

[0072] In the description of this application, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or position relationship indicated by these terms is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0073] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include at least one of such features. In the description of this application, if the term "plurality" appears, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0074] In this application, unless otherwise specified or limited, the terms "mounted," "connected," "connected," "fixed," etc., should be interpreted broadly. For example, these terms may refer to fixed connections, removable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediary; and internal communication between two components or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0075] In this application, unless otherwise expressly specified or limited, if a first feature is described as being "above" or "below" a second feature, or similar descriptions, this may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Furthermore, when a first feature is described as being "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is described as being "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0076] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only embodiment.

[0077] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0078] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
