DETAILED DESCRIPTION

[0029] To make the above objectives, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below in conjunction with the drawings. In the following description, a large number of specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application, so the present application is not limited to the specific embodiments disclosed below.

[0030] Reference Figures 1 to 3 , Figure 1 A simplified schematic diagram of a material refrigeration storage device according to an embodiment of the present application is shown. Figure 2 With Figure 3 A schematic diagram 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 is shown. A material refrigeration storage device according to an embodiment of the present application includes a storage housing 10 and a refrigeration module 20. The storage housing 10 includes, but is not limited to, a cabin, a pot, a container, a box, and various devices with a storage chamber 101. The storage housing 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 outside the storage housing 10, and the refrigeration module 20 is provided with a cold air outlet 21, which is in communication with the first air inlet 102.

[0031] The refrigeration module 20 is detachably connected to the outside of the storage shell 10, so that the refrigeration module 20 can be completely separated from the storage shell 10, and 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. In addition, the purpose of cooling the storage chamber 101 is achieved by the mode of sending cold air, which is beneficial to improve the refrigeration uniformity of the storage chamber 101 and avoid the defects of temperature unevenness and condensed water caused by using solid refrigeration or water cooling to store the chamber 101 in the related art. In addition, the cold air of the cold air outlet 21 enters the inside of the storage chamber 101 through the first air inlet 102, and is discharged outward through the first air outlet 103.

[0032] Please refer to Figures 1 to 3 In an embodiment, the air duct 1011 is formed in the storage chamber 101. The air duct 1011 is in communication with the first air inlet 102 and the first air outlet 103, respectively. In this way, the air duct 1011 forms a reasonable air field in the storage chamber 101, achieving the purpose of uniform temperature in the storage chamber 101. Specifically, during operation, the air duct 1011 plays a guiding role for the cold air entering the first air inlet 102, and the cold air is discharged outward through the first air outlet 103. In addition, the cold air flowing along the air duct 1011 cools each part of the air duct 1011, and the refrigeration uniformity is good.

[0033] The shape of the air duct 1011 can be set in combination with the specific shape of the storage chamber 101, so that the cold air flows as much as possible in each part of the storage chamber 101, thereby improving the refrigeration 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, and irregular shapes. The curve includes but is not limited to various forms such as a ring, an S shape, a Z shape, and an L shape.

[0034] Please refer to Figures 4 to 6 , Figure 4 An exploded structural schematic view of a material refrigeration storage device according to an embodiment of the present application is shown. Figure 5 With Figure 6 respectively show Figure 4 two different perspective structural views of the storage shell 10 in the structure shown. In some embodiments, the storage shell 10 is provided with an openable cover, Figures 4 to 6 which is not shown in the above two figures. When the cover is opened, the material can be loaded into the inside of the storage shell 10 and taken out from the inside of the storage shell 10. In addition, the inside of the storage shell 10 is provided with a mounting rack for loading the material, Figures 4 to 6 which is not shown in the above two figures. The mounting rack includes but is not limited to a reagent disc and the like. In addition, the outer wall of the storage shell 10 is provided with a heat preservation component such as heat preservation cotton, Figures 4 to 6The heat preservation cotton is not shown in the figures, and the heat preservation cotton plays a heat preservation role and is conducive to the refrigeration effect and temperature constancy of the storage chamber 101. In addition, the storage shell 10 can also be provided with other various functional parts according to actual needs.

[0035] Please refer to Figure 2 With Figure 3 In one embodiment, the storage shell 10 includes a wind guide 104 connected to the bottom wall of the storage chamber 101 and in the form of a ring, Figures 4 to 6 The wind guide 104 is not shown in the figures. The wind guide 104 cooperates with the side wall of the storage chamber 101 to form a ring-shaped air duct 1011. The air duct 1011 is specifically provided in the form of a circular ring, an elliptical ring, a polygonal ring, and other irregular shapes. In this way, the cold air entering from the first air inlet 102 flows along the ring-shaped air duct 1011, and the storage chamber 101 has a more uniform refrigeration effect.

[0036] In some embodiments, the wind guide 104 can be flexibly adjusted and arranged according to actual needs, including but not limited to being arranged in the form of a wind guide plate, a wind guide block, and other various structural forms.

[0037] It should be noted that the "wind guide 104" can be "a part of the bottom wall of the storage chamber 101", that is, the "wind guide 104" is integrally formed with "the other part of the bottom wall of the storage chamber 101"; or it can be a separate component that can be separated from "the other part of the bottom wall of the storage chamber 101", that is, the "wind guide 104" can be independently manufactured and then combined with "the other part of the bottom wall of the storage chamber 101" to form an integral whole.

[0038] Please refer to Figure 2 In some embodiments, the first air inlet 102 and the first air outlet 103 are arranged on opposite sides of the air duct 1011. In this way, the first air inlet 102 and the first air outlet 103 are relatively far apart, specifically, for example, distributed at two most distant end points on the air duct 1011. When the first air inlet 102 and the air outlet are at the most distant distance, the air field and temperature field formed in the storage chamber 101 are relatively balanced.

[0039] Please refer to Figure 3In some embodiments, the first air inlet 102 and the first air outlet 103 can also be arranged at two adjacent positions of the air duct 1011 respectively, and the openings of the first air inlet 102 and the first air outlet 103 face opposite directions, i.e., the first air inlet 102 and the first air outlet 103 are arranged back to back, so that the cold air of the first air inlet 102 returns to the first air outlet 103 after circulating around the air duct 1011 and is discharged outward. In this way, the storage chamber 101 and the refrigeration module are connected by a pipe with a diameter of, 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 reduced as much as possible, which is beneficial to reduce the occupation of the space at the bottom of the storage shell 10, and the loss of cold energy through the pipe is reduced.

[0040] Please refer to Figures 4 to 6 In an embodiment, the storage shell 10 is provided with an air inlet nozzle 105 and an air outlet nozzle 106. The first air inlet 102 is arranged on the air inlet nozzle 105, and the first air outlet 103 is arranged on the air outlet nozzle 106. The air inlet nozzle 105 and the air outlet nozzle 106 extend through the storage shell 10 to the outside of the storage shell 10. The air inlet nozzle 105 is in communication with the cold air outlet portion 21. The refrigeration module 20 is provided with an air return portion 22, which is in communication with the air outlet nozzle 106. In this way, under the action of the air inlet nozzle 105 and the air outlet nozzle 106, the cold air can be introduced into the air duct 1011 and circulated in the air duct 1011, so as to improve the uniformity of refrigeration. In addition, the air inlet nozzle 105 and the air outlet nozzle 106 can facilitate the assembly and connection with the refrigeration module 20.

[0041] In addition, when the first air inlet 102 and the first air outlet 103 are arranged at two adjacent positions of the air duct 1011 respectively, and the openings of the first air inlet 102 and the first air outlet 103 face opposite directions, i.e., the air inlet nozzle 105 and the air outlet nozzle 106 are arranged back to back.

[0042] In some embodiments, the air inlet nozzle 105 and the air outlet nozzle 106 are arranged, for example, through the bottom wall, the side wall, etc. of the storage shell 10. In this embodiment, the air inlet nozzle 105 and the air outlet nozzle 106 arranged on the bottom wall of the storage chamber 101 will be taken as an example for expansion.

[0043] Please refer to Figures 4 to 7 , Figure 7A cross-sectional structure simplified diagram of the bottom wall of the storage housing 10 of an embodiment of the present application is shown. In an embodiment, the bottom wall surface of the storage chamber 101 is provided in a curved shape. The first air inlet 102 is arranged at a position with a lower height on the bottom wall. In this way, the cold air entering the first air inlet 102 will flow along the curved bottom wall from the position with a lower height on the bottom wall, and the bottom wall plays a role of turbulence and guidance for the cold air. The high-low design of the bottom wall is more conducive to forming a circular circulating air field in the storage cabin, and the circulating air field makes each temperature point in the storage cabin uniform, effectively reduces the temperature of the storage chamber 101 and reduces the temperature difference in the cabin, thereby reducing the formation of condensed water.

[0044] It should be noted that the position with a lower height refers to a position on the bottom wall that is closer to the workbench surface when the material refrigeration storage device is placed on the workbench surface, and the workbench surface is used as a reference surface. Conversely, the position with a higher height refers to a position on the bottom wall that is farther away from the workbench surface.

[0045] In some embodiments, the position with a lower height and the position with a higher height on the bottom wall are distributed on opposite sides of the storage chamber 101.

[0046] Please refer to Figures 4 to 6 In some embodiments, when the first air outlet 103 is arranged adjacent to and opposite to the first air inlet 102, the first air outlet 103 is also arranged, for example, at a position with a lower height on the bottom wall, that is, arranged on the low surface 1012 of the bottom wall at the same time as the first air inlet 102. Of course, the first air outlet 103 can also be arranged at a position with a higher height on the bottom wall, that is, arranged on the high surface 1013 of the bottom wall, which is not shown in the figure.

[0047] Please refer to Figures 5 to 7 In an embodiment, the bottom wall surface of the storage chamber 101 includes a low surface 1012 with a lower height, a high surface 1013 with a higher height, and a transition surface 1014 connecting the low surface 1012 and the high surface 1013. The transition surface 1014 includes at least one or a combination of a flat surface and a curved surface.

[0048] Please refer to Figures 5 to 7 The curved surface includes but is not limited to various regular shapes such as an arc shape, a parabolic shape, a polyline shape, and other irregular shapes.

[0049] Please refer to Figures 5 to 7 In an embodiment, the distance H between the low surface 1012 and the high surface 1013 is not less than 25 mm. In this way, the greater the distance H between the low surface 1012 and the high surface 1013, the more conducive to improving the turbulence effect and improving the refrigeration effect.

[0050] Please refer to Figure 4 ,Figure 6 With Figure 8 In one embodiment, the cold air outlet 21 is provided with a cold air outlet pipeline, Figure 4 With Figure 8 The cold air outlet pipeline is not shown in FIG. 2, and the cold air outlet pipeline is detachably connected with the storage shell 10. Specifically, the cold air outlet pipeline is detachably connected with the air inlet nozzle 105, for example. In this way, the cold air of the cold air outlet 21 is output to the air inlet nozzle 105 through the cold air outlet pipeline and is input to the inside of the storage chamber 101 through the air inlet nozzle 105. Of course, the air inlet nozzle 105 can be omitted, and when the air inlet nozzle 105 is omitted, the cold air outlet pipeline will be directly connected in communication with the first air inlet 102.

[0051] Please refer to Figure 4 , Figure 6 With Figure 8 In one embodiment, the refrigeration module 20 is also provided with a return air portion 22 in communication with the first air outlet 103. The return air portion 22 is provided with a return air pipeline, Figure 4 With Figure 8 The return air pipeline is not shown in FIG. 2, and the return air pipeline is detachably connected with the storage shell 10. Specifically, the return air pipeline is detachably connected with the air outlet 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 pipeline. Similarly, the air outlet nozzle 106 can be omitted, and when the air outlet nozzle 106 is omitted, the return air pipeline will be directly connected in communication with the first air outlet 103.

[0052] When the cold air outlet pipeline is detachably connected with the air inlet nozzle 105 and the return air pipeline is detachably connected with the air outlet nozzle 106, for example, 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.

[0053] Please refer to Figure 4 , Figure 6 With Figure 8 In some embodiments, the cold air outlet pipeline and the return air pipeline are independently provided, including but not limited to being provided as corrugated pipes, and being wrapped with a thermal insulation component such as thermal insulation cotton having a sufficient thickness on the outer wall of each pipeline, for example.

[0054] Please refer to Figure 4 , Figure 6 With Figure 8In one embodiment, the cold air outlet 21 is provided with at least one first power source 23 for driving the air to be discharged outwards 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, under the power provided by the first power source 23 and / or the second power source 24, the cold air circulates in the annular air flow field formed by the combination of the refrigeration module 20 and the storage chamber 101, and has a better refrigeration effect on the storage chamber 101. In addition, the refrigeration module 20 is moved to the outside of the storage shell 10 by using the air supply, improving the maintainability and maintenance efficiency of the refrigeration module 20.

[0055] Referring to Figure 4 , Figure 6 and Figure 8 In some embodiments, the first power source 23 and the second power source 24 are each independently provided, including but not limited to various power mechanisms such as fans, power pumps, etc., 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 into the refrigeration module 20.

[0056] Referring to Figure 4 , Figure 6 and Figure 8 In some embodiments, the working power of the first power source 23 and the second power source 24 can be adjusted, so that the air volume and air speed of the cold air entering the inside of the storage chamber 101 can be flexibly adjusted and set according to actual needs. Specifically, according to the environmental temperature inside the storage chamber 101 and the cold air temperature of the refrigeration module 20, the working power of the first power source 23 and the second power source 24 is adjusted accordingly to adjust the air volume and air speed of the cold air entering the inside of the storage chamber 101, so that the temperature of the inside environment of the storage chamber 101 can be maintained within a preset range. In addition, the working power of the first power source 23 and the second power source 24 can also be flexibly adjusted according to different use stages, different use modes or different use scenarios of the material refrigeration storage device, so that the environmental temperature inside the storage chamber 101 meets the preset requirements. For example, when the material refrigeration storage device is in the initial stage of use, in order to quickly reduce the environmental temperature inside the storage chamber 101 to the preset temperature, the first power source 23 and the second power source 24 are operated at a higher working power; when the internal environmental 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, for example, opened to take out materials from the inside of the storage chamber 101 or put in new materials, or is maintained, in order to maintain the temperature inside the storage chamber 101 constant, the first power source 23 and the second power source 24 are operated at a higher working power.

[0057] Referring to Figure 4 , Figure 6 and Figure 8 In one embodiment, the first power source 23 and the second power source 24 are both adjustable-speed fans, for example, to adjust the air flow in the storage chamber 101.

[0058] Referring to Figure 4 , Figure 6 and Figure 8 In one embodiment, the refrigeration module 20 is provided with a refrigeration end 25, which is located between the air return portion 22 and the cold air outlet portion 21. The air returned by the air return portion 22 is cooled by the refrigeration end 25 and then output to the cold air outlet portion 21. The material refrigeration storage device further comprises 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 end 25 or the cold air outlet portion 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. In this way, under the control of the controller, the first power source 23, the second power source 24, and the refrigeration module 20 work in coordination to control the temperature of the internal environment of the storage chamber 101 within a preset range, according to the temperatures sensed by the first temperature sensor and the second temperature sensor.

[0059] In addition, when the second temperature sensor senses that the temperature of the refrigeration end 25 or the cold air outlet portion 21 exceeds the threshold temperature, for example, is higher than 1.5°C or lower than 1.5°C, the controller controls the refrigeration module 20 to increase or decrease the working power accordingly; on the contrary, when the second temperature sensor senses that the temperature of the refrigeration end 25 or the cold air outlet portion 21 is the threshold temperature, the controller controls the refrigeration module 20 to maintain the current working power and continue to operate.

[0060] In the above embodiments, the preset temperature and the threshold temperature are both flexibly adjusted and set according to actual needs, which are not limited here.

[0061] In some embodiments, when the second temperature sensor senses that the cold air temperature of the refrigeration end 25 or the cold air outlet portion 21 is higher than the threshold temperature, the controller controls the refrigeration module 20 to increase the working power, and at the same time, the first power source 23 and the second power source 24 each work at a higher working power, for example, the speed of the fan is adjusted to the maximum gear; on the contrary, when the second temperature sensor senses that the cold air temperature of the refrigeration end 25 or the cold air outlet portion 21 is lower than the threshold temperature, the controller controls the refrigeration module 20 to decrease the working power, and at the same time, the first power source 23 and the second power source 24 each work at a lower working power, for example, the speed of the fan is reduced.

[0062] In some embodiments, when the second temperature sensor senses that the temperature of the cold air of the cold air outlet 21 or the cold air end 25 is a threshold temperature, the refrigeration module 20 maintains the current working power. In addition, the temperature of the storage chamber 101 is sensed by the first temperature sensor, and the first power source 23 and the second power source 24 are controlled according to the temperature sensed by the first temperature sensor.

[0063] Please refer to Figure 4 , Figure 6 and Figure 8 In one embodiment, the refrigeration module 20 is also provided with a heat dissipation end 26 and a second air inlet 27 and a second air outlet 28 respectively communicating with the heat dissipation end 26. In this way, the ambient air enters the heat dissipation end 26 through the second air inlet 27, takes away the heat on the heat dissipation end 26, and is discharged outward through the second air outlet 28. The heat dissipation end 26 dissipates heat to the environment, so as to reduce the temperature of the cold air end 25.

[0064] Please refer to Figure 4 , Figure 6 and Figure 8 In one embodiment, at least one third power source 291 for driving air flow to the heat dissipation end 26 is provided at the second air inlet 27. In addition, at least one fourth power source 292 for driving hot air outward is provided at the second air outlet 28. In this way, under the driving of the power provided by the third power source 291 and / or the fourth power source 292, the ambient air flows through the second air inlet 27, the heat dissipation end 26 and the second air outlet in turn, and the heat dissipation end 26 has a better heat dissipation effect.

[0065] In some embodiments, the third power source 291 and the fourth power source 292 are independently provided, including but not limited to various power mechanisms such as fans, power pumps, etc.

[0066] In some embodiments, the working power of the third power source 291 and the fourth power source 292 can be adjusted, so that the amount and speed of air entering the heat dissipation end 26 can be flexibly adjusted and set according to actual needs.
