[0002] With the development of the biological macromolecule industry, the chromatography cabinet as a small volume device providing a low temperature environment is widely used. The common chromatography cabinet usually cools the inside of the cabinet body by a compressor and a fan to achieve the refrigeration effect. However, the compressor is usually integrated on the cabinet body, which generates heat during use, affects the accuracy of temperature control, and increases energy consumption. When the chromatography cabinet needs to be set in a clean environment, the compressor also discharges air flow to the room where the chromatography cabinet is located, affecting the indoor environment. At the same time, the fan takes in air from the room, pollutes the environment inside the chromatography cabinet, and cannot meet the cleanliness requirements. SUMMARY

[0028] Please refer to Figure 2 , Figure 3 and Figure 4 , the cabinet door 13 is arranged on the shell 11 and can be opened and closed relative to the shell 11 to form the closed structure 20 with the shell 11. Specifically, the cabinet door 13 is rotatably arranged on the shell 11 to form the closed structure 20 with the shell 11. The shell 11 comprises an upper wall 111 and a bottom wall 115 arranged opposite to each other, and a side wall 113 between the upper wall 111 and the bottom wall 115. The number of the cabinet door 13 is two. The two cabinet doors 13 are respectively adjacent to the side wall 113 to form a double-leaf door structure.

[0029] A wire hole 114 is formed in the side wall 113 of the shell 11. The wire hole 114 is a sealable hole structure for connecting the materials inside the cabinet body 10 with the outside. For example, the wire hole 114 can be used for passing communication wires, device power supply lines or liquid pipelines, thereby connecting the inside and outside of the cabinet body 10. This is conducive to powering and signal transmission of the devices placed in the cabinet body 10 and taking and placing materials into the cabinet body 10.

[0030] The side wall 113 is further provided with a discharge hole 116, and a one-way valve (not shown) is arranged on the discharge hole 116, so that the liquid can only be discharged from the inside of the cabinet 10 to the outside of the cabinet 10, and impurities outside the cabinet 10 cannot enter the cabinet 10.

[0031] The bottom wall 115 is provided with a collection hole 118 on the side facing the inside of the shell 11, and the collection hole 118 is used to discharge the condensed water in the cabinet 10. By adjusting the inclination of the surface of the bottom wall 115 and arranging the collection hole 118 at the lowest position, the condensed water condensed at any position in the cabinet 10 can flow towards the collection hole 118, so that the condensed water in the cabinet 10 can be fully discharged. A one-way valve (not shown) can also be arranged in the collection hole 118, so that the collection hole 118 can only be used to discharge the condensed water in the cabinet 10, and impurities outside the cabinet 10 cannot enter the cabinet 10 through the collection hole 118.

[0032] The bottom wall 115 is provided with a plurality of moving wheels 121, so as to facilitate the movement of the cabinet 10. The moving wheels 121 can be universal wheels or wheels of other structures, and the present application does not limit this.

[0033] In the embodiment, the cabinet door 13 comprises an outer frame 131 and a glass window 133, and the outer frame 131 surrounds the glass window 133. The material of the glass window 133 is anti-fog glass, which can avoid fogging on the glass window 133 due to the temperature difference between the inside and outside of the cabinet 10. In other embodiments, the cabinet door 13 can also be configured as a whole piece of glass, and the present application does not limit this.

[0034] In some embodiments, the cabinet door 13 is provided with a sealing ring 137 on the side facing the shell 11, and the sealing ring 137 is used to fill the gap between the cabinet door 13 and the shell 11 when the cabinet door 13 and the shell 11 form a closed structure 20. Specifically, in the embodiment, the sealing ring 137 is an inflatable sealing ring, which can be inflated to expand, so as to fill the gap between the cabinet door 13 and the shell 11 when the cabinet door 13 is in a closed state, and ensure the sealing of the inside of the cabinet 10. The sealing ring 137 is provided with an air path valve (not shown), and the air path valve is electrically connected with the control system 50. When it is confirmed that the cabinet door 13 is closed, the control system 50 controls the air path valve to start, so as to inflate the sealing ring 137 to expand, and then realize sealing. In other embodiments, the sealing ring 137 can also be made of elastic material. When the cabinet door 13 is in a closed state, the sealing ring 137 is subjected to a certain pressure, so as to fully fill the gap between the cabinet door 13 and the shell 11, and then realize sealing.

[0035] In other embodiments, the cabinet door 13 and the shell 11 can also be a structure that is not completely sealed. Specifically, the cabinet door 13 can be provided with a downward air outlet (not shown) below, and the gas in the cabinet 10 can be discharged through the air outlet.

[0036] In some embodiments, the glass window 133 is provided with an operation hole 134, and a replaceable glove 135 is arranged on the operation hole 134. The sleeve end of the glove 135 is sealingly connected to the operation hole 134, and the finger end of the glove 135 is used to wrap the user's hand. In this way, the user can operate the interior of the cabinet 10 from the outside of the cabinet 10, while avoiding pollution of the interior of the cabinet 10 by the external environment or pollution of the external environment by the materials in the interior of the cabinet 10.

[0037] In some embodiments, the cabinet 11 further comprises a support 122 and at least one layer plate 126. The support 122 is arranged in the interior of the cabinet 11, and the layer plate 126 is arranged on the support 122 and can be adjusted in position on the support 122 to adapt to materials of different heights. Specifically, in this embodiment, the support 122 is fixed on the side wall 113 and is used to support components arranged in the cabinet 11. The support 122 is provided with buckle or lock structures for carrying the layer plate 126. The buckles or locks on the support 122 can be arranged at different heights, and the layer plate 126 is arranged at different heights by being arranged on different buckles or locks. The buckles or locks can also be movable relative to the support 122, so that when it is necessary to adjust the position of the layer plate 126, the position of the buckle or lock on the support 122 is directly adjusted, and then the layer plate 126 is placed on the adjusted buckle or lock. In other embodiments, the layer plate 126 can also be provided in multiple numbers, which is not limited in the present application.

[0038] In some embodiments, the cabinet 11 is further provided with temperature sensors 123. In this embodiment, a plurality of temperature sensors 123 are arranged at intervals in the cabinet 10 and are used to sense the temperature at different positions in the cabinet 10 to detect the uniformity of the temperature in the cabinet 10. The temperature sensors 123 are electrically connected to the control system 50 and are used to transmit the sensed temperature to the control system 50. The plurality of temperature sensors 123 can be arranged at intervals in the vertical direction to sense the temperature at different heights, can be arranged at different positions on the same layer, or can be configured to be adjusted in position according to the materials placed in the cabinet 10, which is not limited in the present application.

[0039] Optionally, the cabinet 11 can be further provided with an ultraviolet lamp 124 and a lighting lamp 125. The ultraviolet lamp 124 is arranged at one end of the side wall 113 close to the upper wall 111 and is used to project ultraviolet light into the cabinet 10 to perform sterilization. The size and power of the ultraviolet lamp 124 can be set according to the size of the cabinet 10 and specific use requirements. The ultraviolet lamp 124 is electrically connected to the control system 50, and the control system 50 can control the switching and brightness of the ultraviolet lamp 124. According to specific requirements, the number of ultraviolet lamps 124 can be one or more, which is not limited in the present application.

[0040] The lighting lamp 125 is used to provide illumination to the inside of the cabinet 10. The lighting lamp 125 can be arranged on the side wall 113, or on the upper wall 111 or the bottom wall 115. The number of the lighting lamp 125 can be one or multiple, or integrated on the ultraviolet lamp 124, which is not limited in the present application. The lighting lamp 125 is connected with the control system 50, and the control system 50 can control the switch and brightness of the lighting lamp 125.

[0041] In some embodiments, the cabinet 10 further comprises a flow equalizing plate 16 arranged between the fan 15 and the cooling pipe 17. Optionally, the cabinet 10 can further comprise a filter layer 18 arranged on the side of the cooling pipe 17 away from the fan 15.

[0042] In some embodiments, the fan 15, the flow equalizing plate 16, the cooling pipe 17 and the filter layer 18 are arranged close to the top of the closed structure 20.

[0043] Specifically, the fan 15 is used to blow air towards the inside of the cabinet 10, and when the airflow flows through the cooling pipe 17, the air with lower temperature near the cooling pipe 17 can be brought to other positions in the cabinet 10, so as to reduce the overall temperature in the cabinet 10. When the fan 15, the flow equalizing plate 16, the cooling pipe 17 and the filter layer 18 are arranged close to the top of the closed structure 20, the cold air after the cooling pipe 17 can continue to flow downwards, and the air with higher temperature in the cabinet 10 can flow upwards, so as to form a circulation, and improve the cooling effect and uniformity. The fan 15 can be a variable frequency fan, and the fan 15 is electrically connected with the control system 50, and the control system 50 can control the switch and wind power of the fan 15, so as to adjust the temperature in the cabinet 10.

[0044] The flow equalizing plate 16 is arranged at the air outlet of the fan 15, and is used to buffer the airflow blown out from the fan 15. Specifically, the airflow blown out from the fan 15 usually flows along the direction of the air outlet, that is, the flow rate of the airflow is faster at the position directly opposite to the air outlet, and slower at the position not directly opposite to the air outlet. In a closed environment, the airflow is easy to be turbulent, which is not conducive to the uniform cooling of the cabinet 10, and is also not conducive to the placement of the materials. By arranging the flow equalizing plate 16, the airflow blown out from the fan 15 can be uniformly distributed, so that the airflow flowing out from the flow equalizing plate 16 is more stable.

[0045] The cooling pipe 17 is used to carry the cooling liquid transmitted from the refrigeration system 30 and transmit the cooling liquid back to the refrigeration system 30, thereby forming a closed loop. Specifically, the cooling pipe 17 comprises an inlet port 171 and an outlet port 173 connected to the outside of the cabinet 10, the inlet port 171 is used to receive the cooling liquid transmitted from the refrigeration system 30, and the outlet port 173 is used to output the cooling liquid from the cabinet 10 back to the refrigeration system 30. The height of the inlet port 171 is higher than that of the outlet port 173, so that the cooling liquid flowing into the cooling pipe 17 can flow towards the outlet port 173 under the action of gravity, thereby reducing energy consumption.

[0046] The cooling pipe 17 is arranged at least partially close to the top of the closed structure 20 and corresponds to the air outlet of the fan 15, so that the air flow blown out from the flow distribution plate 16 is blown onto the cooling pipe 17. Specifically, when the cooling liquid after refrigeration flows through the cooling pipe 17, the temperature of the cooling pipe 17 will decrease due to heat conduction, and the temperature of the surrounding air will decrease, at this time, the fan 15 is started, and the air flow will continuously blow to the cooling pipe 17, thereby bringing the air with lower temperature near the cooling pipe 17 to the cabinet 10, and the air blown to the cooling pipe 17 will continue to be cooled, thereby continuously providing cold air to the cabinet 10.

[0047] In some embodiments, the cooling pipe 17 also covers the side wall 113. Optionally, referring to Figure 5 , the cabinet 10 further comprises a heat preservation layer 19 arranged in close contact with the side wall 113, and the cooling pipe 17 is arranged on the side of the heat preservation layer 19 away from the side wall 113. The heat preservation layer 19 is used to isolate the temperature difference between the inside and outside of the cabinet 10, thereby reducing the speed of temperature rise in the cabinet 10. The cooling pipe 17 is used to further improve the refrigeration effect and improve the uniformity of refrigeration.

[0048] The cooling pipe 17 is specifically a zigzag extending coil pipe, which increases the surface area and thereby increases the area of contact with air, so that the air can be sufficiently cooled when the cooling liquid flows through. In this embodiment, the inlet port 171 is located at a position close to the top end of the cabinet 10, the outlet port 173 is located at a position close to the bottom end of the cabinet 10, and the cooling pipe 17 zigzag extends from the position of the inlet port 171 on the top of the closed structure 20, thereby filling the space between the flow distribution plate 16 and the filter layer 18, and then extends along the side wall 113 and finally extends to the outlet port 173. More specifically, as shown in Figure 5 , the cooling pipe 17 forms a surrounding structure along the top side of the closed structure 20 and the two side walls 113, and each side of the cooling pipe 17 can be arranged as multiple layers forming a circulation loop to achieve faster cooling of the inside of the cabinet 10.

[0049] The filter layer 18 is used to filter the air flow blown by the fan 15. Specifically, the air flow passing through the fan 15, the flow equalizing plate 16 and the cooling pipe 17 can be contaminated, which can cause pollution in the cabinet 10. By arranging the filter layer 18, the air blown by the fan 15 can be filtered, so as to ensure the cleanliness of the air in the cabinet 10.

[0050] In the embodiment, the cooling liquid in the refrigeration system 30 can be an antifreeze liquid such as ethylene glycol. In other embodiments, different parameters of cooling liquid can be selected according to the size of the chromatography cabinet 100 and the required refrigeration temperature, which is not limited in the application. The refrigeration system 30 further comprises a variable frequency circulating pump (not shown in the figure), which is used to pump the cooling liquid in the circuit to the liquid inlet 171, so that the cooling liquid continuously circulates in the closed circuit of the refrigeration system 30 and the cabinet 10. The variable frequency circulating pump is electrically connected with the control system 50, and the control system 50 can control the frequency of the variable frequency circulating pump, so as to adjust the flow rate of the cooling liquid, and then realize the control of the temperature.

[0051] The control system 50 is used to monitor the temperature in the cabinet 10, and send corresponding control signals according to the sensed temperature. Specifically, when the control system 50 detects that the temperature in the cabinet 10 does not reach the set temperature, the control system 50 sends a signal to the refrigeration system 30, so that the refrigeration system 30 starts to cool the cooling liquid and pumps the cooling liquid into the cabinet 10. The control system 50 is also used to control the flow rate of the cooling liquid, so as to realize the control of the cooling speed. The control system 50 also controls the fan 15 to start, so that the gas with lower temperature near the cooling pipe 17 is blown into the cabinet 10. The control system 50 can also control the speed of the fan 15, so as to realize the control of the cooling speed, that is, the greater the speed of the fan 15, the more air flow is blown out, the more sufficient the cooling of the gas by the cooling pipe 17, and the faster the cooling speed of the inside of the cabinet 10. When the control system 50 detects that the temperature in the cabinet 10 reaches the set temperature, the control system 50 can stop the refrigeration system 30 and the fan 15, or reduce the flow rate of the cooling liquid in the refrigeration system 30, or reduce the speed of the fan 15, so as to keep the temperature in the cabinet 10 at the set temperature.

[0052] In the embodiment, the control system 50 further comprises a touch display panel, which can be embedded on the shell 11, so as to allow the user to view the parameters of the chromatography cabinet 100 and send instructions. In other embodiments, the control system 50 can also be communicatively connected with another remote terminal, and the user can control the remote terminal to send instructions to the chromatography cabinet 100, which is not limited in the application.

[0053] The chromatography cabinet 100 provided by the embodiment of the present application can avoid setting a compressor, thereby being beneficial to reducing heat dissipation of the cabinet 10, reducing energy consumption, and excluding heat interference generated by the compressor, and being beneficial to accurately controlling temperature. Moreover, the refrigeration system 30 of the liquid cooling refrigeration cannot exhaust air to a space where the chromatography cabinet 100 is located, and is beneficial to reducing air turbulence.

[0054] Those skilled in the art should understand that the above implementation is only used to illustrate the present application, and is not used as a limitation to the present application, and as long as the above embodiments are appropriately changed and changed within the scope of the spirit of the present application, they fall within the scope of the present application.
