Description

[0002] At present, the existing biochemical analyzers mainly use the method of circulating refrigerant to take away the temperature in the reagent bin to achieve the refrigeration of the reagent bin. The existing biochemical analyzers are basically introduced from abroad. They adopt the nested reagent pot solution, and the inner and outer layers of the pot are welded together through a welding process to form a hollow structure with side walls and bottom, so that the refrigerant can flow in it to exchange heat with the reagent bin. Since the nested reagent pot solution has two layers of pot walls, and the two layers of pot walls must be hollow for the flow of refrigerant, the nested reagent pot occupies a large space.

[0052] Reference Figures 1 to 9 The present invention proposes a reagent chamber including a main structure, a rotating drive member and a turntable, wherein the main structure forms a cooling cavity and an installation cavity. An observation window is provided on the side wall of the main structure, and the turntable is installed in the installation cavity. The rotating drive member can drive the turntable to rotate in the installation cavity, so that the barcode on the reagent or sample container placed on the turntable can be displayed through the observation window for scanning. A fluid with a refrigeration function such as a refrigerant or a coolant can be introduced into the cooling cavity to cool the reagent chamber and reduce the temperature of the reagent chamber, thereby improving the activity of the sample and increasing the storage time of the reagent and the sample.

[0053] In an embodiment of the present invention, the reagent chamber 100 includes a chamber body 10 and a cover plate 20. The chamber body 10 includes a bottom plate 11 and a side plate 12. The side plate 12 is connected to the bottom plate 11 and is circumferentially arranged around the side plate 12. The bottom plate 11 divides the space enclosed by the side plate 12 into an installation cavity 10a and a cooling cavity 10b. The cover plate 20 is connected to the side plate 12 and covers the opening of the cooling cavity 10b away from the bottom plate 11. A liquid passage 10c is formed in the cooling cavity 10b. The reagent chamber 100 is provided with an inlet 20a and an outlet 20b connected to the liquid passage 10c.

[0054] Among them, the side plate 12 can be set to a square tube or a cylindrical shape according to the needs, and the bottom plate 11 and the cover plate 20 can be a square plate or a circular plate. In the present application, in order to facilitate the rotation of the driving member to drive the turntable to rotate in the installation cavity 10a, the side plate 12 is set in a cylindrical shape, and the bottom plate 11 and the cover plate 20 are set in a circular plate. The warehouse body 10 and the cover plate 20 provided in the present application can be connected by welding, or by clamping or screw connection. In the present application, the warehouse body 10 and the cover plate 20 are connected as a whole by screw connection, so that not only can the connection strength between the warehouse body 10 and the cover plate 20 be guaranteed, but also the reagent warehouse 100 provided in the present application does not involve welding process during assembly, the reliability of assembly between structures is high, the assembly cost is low, and there will be no yield problem caused by poor welding. The rotating driving member of the reagent warehouse 100 provided in the present application can be set in the installation cavity 10a, or a part of the structure can pass through the bottom plate 11 and the cover plate 20 to connect with the turntable.

[0055] The side panel 12 of the reagent chamber 100 provided in the present application has a window 12a for displaying the barcode on the container, and a connecting plate made of transparent material such as glass is connected to the position of the window 12a formed on the side panel 12 to close the installation cavity 10a to ensure that the temperature in the installation cavity 10a can be reduced and stabilized.

[0056] The reagent bin 100 provided by the technical solution of the present invention comprises a bin body 10 and a cover plate 20, wherein the bin body 10 comprises a bottom plate 11 and a side plate 12, wherein the bottom plate 11 can separate the space enclosed by the side plate 12 to form a mounting cavity 10a for loading a turntable and a cooling cavity 10b for cooling the reagent bin 100. The cover plate 20 can cover the side of the cooling cavity 10b away from the bottom plate 11 to close the cooling cavity 10b and ensure that the refrigerant can flow in the cooling cavity 10b. When cooling the reagent bin 100, the refrigerant can be introduced from the inlet 20a so that the refrigerant enters the cooling cavity 10b and flows in the liquid passage 10c. During the circulation of the refrigerant in the liquid passage 10c, the refrigerant will exchange heat with the reagent bin 100 to reduce the temperature of the reagent bin 100, thereby increasing the storage time of the reagent or sample placed in the turntable. The refrigerant passing through the liquid passage 10c will eventually flow out from the outlet 20b to ensure that the cooling chamber 10b can continuously pass the refrigerant without heat exchange, thereby ensuring the cooling effect of the reagent chamber 100 and ensuring that the temperature of the reagent chamber 100 can drop to the preset temperature.

[0057] In addition, compared to the embedded pot-type reagent chamber 100, the reagent chamber 100 provided in the present application only needs to connect the cover plate 20 and the chamber body 10 when assembling to form a cooling chamber 10b for passing refrigerant, thereby reducing the number of installation positions to which the reagent chamber 100 needs to be connected to form the cooling chamber 10b, reducing the process requirements when the reagent chamber 100 is connected and installed, and reducing the cost of production.

[0058] In order to facilitate welding, the main structure of the nested pot in the related art is generally made of stainless steel. However, the heat exchange capacity between the stainless steel material and the air in the reagent bin 100 is low, and the reagent refrigeration effect in the reagent bin 100 is poor. In an embodiment of the present application, the bin body 10 is made of aluminum alloy material, or the bin body 10 and the cover plate 20 are made of aluminum alloy material. The use of aluminum alloy material to make the bin body 10 and the cover plate 20 can improve the thermal conductivity of the reagent bin 100, thereby improving the heat exchange efficiency between the refrigerant in the cooling cavity 10b and the hot air in the installation cavity 10a.

[0059] In order to improve the connection strength between the bottom plate 11 and the side plate 12, and to facilitate the manufacturing and processing of the warehouse main body 10, the warehouse main body 10 can be an integrated structure. Of course, in order to manufacture and process the various structures on the bottom plate 11, the bottom plate 11 and the side plate 12 can also be made into a detachable and concealed structure.

[0060] In an embodiment of the present application, the reagent chamber 100 further includes a seal, which is disposed between the bottom plate 11 and the cover plate 20 and can seal the cooling chamber 10b. It can be understood that the seal can ensure the sealing of the cooling chamber 10b and prevent the refrigerant in the cooling chamber 10b from leaking.

[0061] See also Figure 2In one embodiment of the present application, the reagent chamber 100 is provided with a rotating driving member and a turntable. The rotating driving member is connected to the turntable and can drive the turntable to rotate. The bottom plate 11 and the cover plate 20 are provided with a first clearance opening 11b and a second clearance opening 20c for the rotating driving member to pass through. The turntable is arranged in the installation cavity 10a.

[0062] It can be understood that arranging the rotating drive member outside the installation cavity 10a can save the space occupied by the installation cavity 10a and reduce the size of the installation cavity 10a, thereby reducing the occupied space of the reagent warehouse 100. The first clearance port 11b and the second clearance port 20c can avoid the rotating drive member 400, ensuring that the rotation drive can drive the turntable to rotate. The rotating drive member may include a driving body and a rotating shaft. The rotating drive member may be arranged on the side of the cover plate 20 away from the cooling chamber 10b in order to improve the stability of the connection and installation with the cover plate 20 and the warehouse body 10, and the rotating shaft passes through the first clearance port 11b and the second clearance port 20c and is connected to the turntable in the installation cavity 10a to drive the turntable to rotate. Of course, the rotating drive member can also be inserted into the space formed by the first clearance port 11b and the second clearance port 20c in order to further reduce the size of the reagent warehouse 100.

[0063] In order to ensure the airtightness of the cooling chamber 10b, the sealing member may include an inner ring sealing ring and an outer ring sealing ring. The inner ring sealing ring is arranged between the bottom plate 11 and the cover plate 20, and seals the cooling chamber 10b toward the first make way opening 11b and the second make way opening 20c. The outer ring sealing ring is arranged between the bottom plate 11 and the cover plate 20, and seals the cooling chamber 10b away from the first make way opening 11b and the second make way opening 20c.

[0064] See also Figure 3 In an embodiment of the present application, a mounting rib 111 is provided on the side of the bottom plate 11 facing the cover plate 20, and the mounting rib 111 includes an inner ring rib 1111 and an outer ring rib 1112. The inner ring rib 1111 is connected to the bottom plate 11 and is arranged around the first clearance opening 11b. The inner ring sealing ring is connected to the inner ring rib 1111 to seal the side of the cooling cavity 10b facing the inner ring rib 1111. The outer ring rib 1112 is connected to the bottom plate 11 and is arranged around the circumference of the bottom plate 11. The outer ring sealing ring is connected to the outer ring rib 1112 to seal the side of the cooling cavity 10b facing the outer ring rib 1112.

[0065] It can be understood that the inner ring rib 1111 can be used to connect and fix the inner ring sealing ring, and the outer ring rib 1112 can be used to connect and fix the outer ring sealing ring. In order to simplify the structure of the bottom plate 11 and facilitate the installation of the inner ring sealing ring, the inner ring rib 1111 can be provided with one, and at this time the inner ring sealing ring is formed with a clamping groove, the inner ring rib 1111 is inserted in the clamping groove, and the inner ring sealing ring abuts between the inner ring rib 1111 and the cover plate 20. In order to improve the stability of the installation and fixation of the sealing ring, two inner ring ribs 1111 can be provided, and the two inner ring ribs 1111 are arranged at intervals and enclosed with the bottom plate 11 to form a first installation groove 111a, and the inner ring sealing ring is installed in the first installation groove 111a and abuts against the cover plate 20. To ensure the sealing effect of the cooling chamber 10b toward the first clearance port 11b and the second clearance port 20c, to ensure that the refrigerant does not leak. Of course, the inner ring ribs 1111 may also be provided with three, four or more, to ensure that it can cooperate with the cover plate 20 to install and fix the inner ring seal ring, so as to ensure the sealing effect of the cooling cavity 10b toward the first clearance opening 11b and the second clearance opening 20c. Similarly, the outer ring ribs 1112 may also be provided with one, two or more.

[0066] See also Figure 4 In the embodiment of the present application, in order to simplify the structure of the bottom plate 11 while ensuring the stability of the installation of the inner ring sealing ring, and to facilitate the manufacture and processing of the bottom plate 11, two inner ring ribs 1111 may be provided, and the two inner ring ribs 1111 are arranged at intervals, and enclosed with the bottom plate 11 to form a first installation groove 111a, and the inner ring sealing ring is installed in the first installation groove 111a and abuts against the cover plate 20. Similarly, in order to simplify the structure of the bottom plate 11 while ensuring the stability of the installation of the outer ring sealing ring, two outer ring ribs 1112 may be provided, and the two outer ring ribs 1112 are arranged at intervals, and enclosed with the bottom plate 11 to form a second installation groove 111b, and the outer ring sealing ring is installed in the second installation groove 111b and abuts against the cover plate 20.

[0067] See also Figure 4 In one embodiment of the present application, a guide rib 112 is provided on one side of the bottom plate 11 facing the cover plate 20, and the guide rib 112 divides the cooling chamber 10b to form a liquid passage 10c. The liquid passage 10c formed by dividing the cooling chamber 10b by the guide rib 112 can be used for the circulation of the refrigerant, thereby increasing the circulation range of the refrigerant in the cooling chamber 10b, so that the refrigerant entering the cooling chamber 10b can fully exchange heat with the chamber body 10, thereby improving the heat exchange efficiency between the refrigerant and the reagent chamber 100.

[0068] The guide rib 112 includes a first dividing rib 1121 and a second dividing rib 1122. The first dividing rib 1121 is arranged in the cooling chamber 10b, and divides the cooling chamber 10b into a first inner ring channel 112b located in the inner ring and a first outer ring channel 112a located in the outer ring. The second dividing rib 1122 is at least partially arranged in the first inner ring channel 112b, and divides the first inner ring channel 112b into a second inner ring channel 112d located in the inner ring and a second outer ring channel 112c located in the outer ring. The guide rib 112 is formed with a first connecting port 112e connecting the first outer ring channel 112a and the second outer ring channel 112c, and a second connecting port 112f connecting the second inner ring channel 112d and the second outer ring channel 112c. One of the inlet 20a or the outlet 20b is arranged in the first outer ring channel 112a, and the other of the inlet 20a or the outlet 20b is arranged in the second inner ring channel 112d.

[0069] It can be understood that the first dividing rib 1121 and the second dividing rib 1122 can divide the cooling chamber 10b into the first outer ring channel 112a, the second inner ring channel 112d and the second outer ring channel 112c, and the second inner ring channel 112d and the second outer ring channel 112c constitute the first inner ring channel 112b. The first connecting port 112e and the second connecting port 112f can ensure the connection between the channels. After the refrigerant enters the cooling chamber 10b from the inlet 20a, it will first flow through the second inner ring channel 112d, then enter the second outer ring channel 112c, and finally flow into the first outer ring channel 112a and be discharged from the outlet 20b. In order to increase the circulation range of the refrigerant in the cooling chamber 10b, the heat exchange efficiency between the refrigerant and the reagent bin 100 is improved. In addition, the guide ribs are arranged in this way to make the bottom plate 11, the side plate 12 and the cover plate 20 more uniform in heat conduction, which can improve the heat exchange effect between the reagent bin 100 and the refrigerant.

[0070] The liquid passage 10c formed by the first dividing rib 1121 and the second dividing rib 1122 can be set as a multi-conducting channel to increase the circulation rate of the refrigerant. Of course, the liquid passage 10c can also be set as a unidirectionally conducting channel to discharge the refrigerant that has completed heat exchange from the cooling chamber 10b in time and improve the cooling effect of the refrigerant and the reagent chamber 100.

[0071] See also Figure 4When the liquid passage 10c is also a unidirectional conductive channel, the first dividing rib 1121 may include a first dividing segment 1121a and a first guiding segment 1121b. The first dividing segment 1121a has two oppositely arranged ends, and the two ends of the dividing segment are respectively connected to the inner ring rib 1111 and the outer ring rib 1112 to separate the annular cooling chamber 10b. The first guiding segment 1121b is arranged in the cooling chamber 10b and divides the cooling chamber 10b into the first inner ring channel 112b and the first outer ring channel 112a. One end of the first guiding segment 1121b is connected to one side of the first dividing segment 1121a, and the other end is spaced apart from the other side of the first dividing segment 1121a for the second dividing rib 1122 to pass through. The other end of the first guiding segment 1121b can be enclosed with the second dividing rib 1122 to form the first connecting port 112e. The second dividing rib 1122 includes a second dividing section 1122a and a second guiding section 1122b. The second dividing section 1122a is connected to the outer ring rib 1112 and extends into the first inner ring channel 112b through the first dividing section 1121a and the first guiding section 1121b which are arranged at intervals. The second guiding section 1122b is arranged in the first inner ring channel 112b and divides the first inner ring channel 112b into the second inner ring channel 112d and the second outer ring channel 112d. 12c, one end of the second guide section 1122b is connected to one end of the second partition section 1122a away from the outer ring rib 1112, and the other end is connected to the first partition section 1121a and the side of the first guide section 1121b to form a second connecting port 112f, the inlet 20a is arranged between the first partition section 1121a and the second partition section 1122a, and the outlet 20b is arranged on the side of the first partition section 1121a away from the inlet 20a, and is arranged in the first outer ring channel 112a. Such a setting can not only increase the circulation range of the refrigerant, improve the heat exchange effect between the refrigerant and the reagent chamber 100, but also make the structure of the guide rib 112 that separates the cooling chamber 10b to form the liquid passage 10c more concise, and facilitate the production and processing of the bottom plate 11.

[0072] Since there is hot air in the installation cavity 10a, when the refrigerant exchanges heat with the reagent compartment 100, the hot air in the installation cavity 10a will be cooled to produce condensed water. In order to facilitate the discharge of condensed water, a drain port 11a connected to the installation cavity 10a can be provided on the side plate 12 or the bottom plate 11, and the drain port 11a is connected to the installation cavity 10a. The drain port 11a can be connected to an external liquid receiving container to facilitate the collection of condensed water and prevent the condensed water from being discharged at will.

[0073] See also Figure 2 and Figure 4In an embodiment of the present application, a drain port 11a is disposed on the bottom plate 11, and the drain port 11a is disposed near the connection between the bottom plate 11 and the side plate 12. The direction from the middle of the bottom plate 11 toward the side plate 12 is defined as a first direction, and the bottom plate 11 is inclined along the first direction toward the cooling chamber 10b.

[0074] It can be understood that the bottom plate 11 is tilted toward the cooling chamber 10b along the first direction, so that the bottom plate 11 is arranged in a shape with a high middle portion and low surrounding portions toward the installation chamber 10a. The bottom plate 11 arranged in this way is conducive to the collection of condensed water and can guide the condensed water, so that the condensed water generated in the installation chamber 10a can be guided to flow into the drain port 11a under the action of gravity to be discharged from the installation chamber 10a.

[0075] The spacing between the bottom plate 11 and the cover plate 20 can be defined as W, and the bottom plate 11 being inclined toward the cooling cavity 10b along the first direction can be understood as: the bottom plate 11 is gradually reduced along the middle of the bottom plate 11 toward the side plate 12 direction W. Of course, it can also be understood that the thickness of the bottom plate 11 is gradually reduced along the first direction, so that the bottom plate 11 forms an inclined surface toward the installation cavity 10a, thereby guiding the condensed water.

[0076] In order to further increase the speed of condensation and flow of condensed water and improve the function of guiding condensed water at the bottom, a hydrophobic layer can be provided on the side of the bottom plate 11 facing the installation cavity 10a. The hydrophobic layer can be a hydrophobic material installed on the surface of the bottom plate 11 facing the installation cavity 10a or a hydrophobic paint coated on the surface of the bottom plate 11 facing the installation cavity 10a.

[0077] See also Figure 4 In an embodiment of the present application, the bottom plate 11 is provided with a drainage port 11a, and a first convex rib 113 is provided on the side of the bottom plate 11 facing the mounting cavity 10a. The first convex rib 113 encloses a first drainage channel 11c, and the first drainage channel 11c is connected to the drainage port 11a.

[0078] It can be understood that the setting of the first convex rib 113 can increase the contact area between the bottom plate 11 and the hot air in the installation cavity 10a, thereby increasing the coldness of the refrigerant conducted by the bottom plate 11 and improving the heat exchange efficiency between the reagent compartment 100 and the hot air in the installation cavity 10a. The first drainage channel 11c formed by the first convex rib 113 facilitates the condensed water to flow to the drainage port 11a and thus be discharged from the installation cavity 10a. Similarly, in order to increase the contact area between the side plate 12 and the hot air in the installation cavity 10a and enhance the heat exchange efficiency between the reagent compartment 100 and the hot air in the installation cavity 10a, a second convex rib can also be provided on the side of the side plate 12 facing the installation cavity 10a. The second convex rib can be enclosed to form a second drainage channel, and the second drainage channel is connected to the drainage port, so as to facilitate the condensed water to flow to the drainage port 11a and thus be discharged from the installation cavity 10a. In order to improve the drainage effect of the second convex rib, the second convex rib can be extended toward the bottom plate. It can be understood that the reagent chamber 100 provided in the present application can be provided with only one of the first convex rib 113 and the second convex rib according to needs, or the first convex rib 113 and the second convex rib can be provided at the same time, which is not limited here.

[0079] At least two first ribs 113 and second ribs may be provided. For example, two, three or more first ribs 113 and second ribs may be provided, which is not limited here. Increasing the number of first ribs 113 and second ribs can increase the contact area between the chamber body 10 and the air in the installation cavity 10a, so as to further improve the cooling effect of the reagent chamber 100. The density, position and height of the first ribs 113 and second ribs can be set according to the specific conditions in the installation cavity 10a of the reagent chamber 100, so as to increase the contact area between the chamber body 10 and the hot air in the installation cavity 10a, destroy the contact thermal resistance between the hot air in the installation cavity 10a and the wall of the reagent chamber 100, and improve the heat exchange efficiency between the reagent chamber 100 and the hot air in the installation cavity 10a. For example, see Figure 4 In the present application, the first rib 113 may include a plurality of sub-ribs 1131, which are arranged at equal intervals and in a ring shape. The first rib 113 is provided with a plurality of sub-ribs 1131, which are arranged at intervals in a direction away from the middle of the bottom plate 11, and the lengths of the sub-ribs 1131 of the plurality of first ribs 113 gradually increase from the direction away from the middle of the bottom plate 11. Such an arrangement can more efficiently utilize the structure of the bottom plate 11 facing the installation cavity 10a, increase the density between the sub-ribs 1131, and improve the heat exchange efficiency between the first rib 113 and the hot air in the installation cavity 10a. In addition, the condensed water can be gathered in various directions of the bottom plate 11 so as to flow to the drain port 11a for discharge.

[0080] A drainage pipe connected to the drainage port 11 a may be formed on one side of the bottom plate 11 facing the cover plate 20 , and the cover plate 20 is provided with an escape opening for the drainage pipe to pass through.

[0081] See also Figure 3 In order to increase the space in the cooling chamber 10b, the inner ring rib 1111 can be arranged adjacent to the first clearance port 11b, and the outer ring rib 1112 can be arranged adjacent to the side plate 12. In order to avoid the drain port 11a, part of the structure of the outer ring rib 1112 adjacent to the drain port 11a can be recessed toward the cooling chamber 10b. In order to ensure the consistency of the flow at each position of the first outer ring channel 112a formed by the outer ring rib 1112 and the first dividing rib 1121, the first dividing rib 1121 can be recessed toward the first inner ring channel 112b corresponding to the outer ring rib 1112. Similarly, the second dividing rib 1122 can also be recessed toward the second inner ring channel 112d corresponding to the first dividing rib 1121.

[0082] See also Figure 1 The present invention also proposes a refrigeration system 1000, which includes a refrigeration module 200, a driving member 400, a water tank 300 and a reagent chamber 100. The specific structure of the reagent chamber 100 refers to the above embodiment. Since the present refrigeration system 1000 adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here. Among them, the water tank 300 is connected to the outlet 20b of the cooling chamber 10b and is connected to the refrigeration module 200, and the refrigeration module 200 is connected to the inlet 20a of the cooling chamber 10b. The driving member 400 is connected to the circuit connecting the reagent chamber 100, the water tank 300 and the refrigeration module 200.

[0083] The refrigeration module 200 can be a compressor module or a semiconductor refrigeration chip module, etc. The refrigeration module 200 can cool the refrigerant after the heat exchange is completed, so that the refrigerant can be recycled in the refrigeration system 1000. The setting of the water tank 300 can prevent the dead volume air existing in the refrigeration system 1000 from constantly circulating in the refrigeration system 1000 and causing damage to the driver 400. The driver 400 can be a pump structure, and the driver 400 can drive the refrigerant to circulate in the loop formed by the refrigeration module 200, the water tank 300 and the reagent bin 100, so that the cooled refrigerant can enter the liquid passage 10c to cool the reagent bin 100. The refrigerant flowing out from the reagent bin 100 can flow back to the refrigeration module 200 through the water tank 300 for cooling, thereby realizing the recycling of the refrigerant.

[0084] See also Figure 5 In an embodiment of the present application, the water tank 300 is provided with a liquid inlet 300a and a liquid outlet 300b which are connected to each other. The liquid inlet 300a is connected to the reagent chamber 100, and the liquid outlet 300b is connected to the refrigeration module 200. The water tank 300 is also provided with a liquid filling port 300c and an overflow port 300d. The overflow port 300d and the liquid outlet 300b are arranged at intervals along the placement direction of the water tank 300.

[0085] It can be understood that the liquid inlet 300a is communicated with the outlet 20b of the reagent compartment 100, and the liquid outlet 300b is communicated with the inlet of the refrigeration module 200, so that the refrigerant that completes the heat exchange in the reagent compartment 100 can enter the water tank 300 from the liquid inlet 300a, and flow from the liquid outlet 300b of the water tank 300 to the inlet of the refrigeration module 200, thereby flowing into the refrigeration module 200 for refrigeration. Adding the water tank 300 to the refrigeration system 1000 can not only prevent the dead volume air existing in the refrigeration system 1000 from constantly circulating in the system and causing damage to the driving member 400, but also facilitate the injection and addition of the refrigerant. When the water tank 300 is placed on a countertop or the ground, the liquid outlet 300b is arranged below the water tank 300 in the placement direction, so that the refrigerant is discharged from the water tank 300. Before the refrigeration system 1000 works, the operator can pass the refrigerant into the water tank 300 through the injection port 300c, so that the refrigerant can circulate in the refrigeration system 1000 to cool the reagent compartment 100. When the water tank 300 is placed on a table or the ground, the overflow port 300d is arranged above the placement direction of the water tank 300. The operator can judge the capacity of the refrigerant in the water tank 300 by observing whether the refrigerant overflows from the overflow port 300d, thereby judging whether the capacity of the added refrigerant is appropriate. In order to prevent the refrigerant overflowing from the overflow port 300d from being discharged at will, the overflow port 300d can be connected to a container such as a beaker that can be loaded with refrigerant.

[0086] The water tank 300 is provided with a liquid inlet 300a and a liquid outlet 300b which are connected to each other, so as to connect the reagent compartment 100 and the refrigeration module 200 through the liquid inlet 300a and the liquid outlet 300b. Figure 5 In an embodiment of the present application, a liquid level sensor 31 may be further provided in the water tank 300. The water tank 300 is provided with a liquid guide tube 32. The liquid guide tube 32 is inserted into the water tank 300 and extends to the bottom of the water tank 300. The liquid guide tube 32 is connected to the liquid inlet 300a.

[0087] It can be understood that the liquid level sensor 31 can be used to detect the remaining amount of refrigerant in the refrigeration system 1000 to determine whether new refrigerant needs to be injected to ensure the cooling effect of the refrigeration system 1000. The liquid guide tube 32 can be inserted into the water tank 300 through the liquid inlet 300a, and the liquid guide tube 32 is extended to the bottom of the water tank 300, which can prevent the refrigerant newly entering the water tank 300 and / or the refrigerant in the water tank 300 from splashing onto the liquid level sensor 31 when the refrigerant enters the water tank 300 from the liquid inlet 300a, thereby interfering with the detection of the liquid level sensor 31 and affecting the accuracy of the detection of the liquid level sensor 31.

[0088] The liquid conduit 32 is provided with a liquid port 32a for the refrigerant to flow from the inlet 20a into the water tank 300. When the refrigeration system 1000 is in operation, the liquid port 32a can be immersed in the refrigerant in the water tank 300 to prevent the refrigerant from splashing. In order to further ensure that the refrigerant entering the water tank 300 does not interfere with the detection of the liquid level sensor 31, the liquid port 32a can be arranged on the side of the liquid conduit 32 away from the liquid level sensor 31.

[0089] The present application sets a water tank 300 in the refrigeration system 1000, which can not only prevent the dead volume air existing in the refrigeration system 1000 from constantly circulating in the refrigeration system 1000 and causing damage to the driving component 400, but also facilitate the remaining monitoring and addition of refrigerant in the refrigeration system 1000.

[0090] See also Figures 6 to 9 In one embodiment of the present application, when the refrigeration module 200 is a semiconductor refrigeration plate module, the refrigeration module 200 may include a refrigeration block 21, a heat exchange component 22, a first temperature sensor 23 and a controller. A cooling channel is formed in the refrigeration block 21. The refrigeration block 21 is provided with an inlet and an outlet connected to the cooling channel. A plurality of heat exchange components 22 are provided, and the plurality of heat exchange components 22 are connected to the outer surface of the refrigeration block 21 at intervals. A plurality of first temperature sensors 23 are provided, and a heat exchange component 22 is connected to a temperature sensor. The controller includes a plurality of sub-controllers. A sub-controller, a heat exchange component 22 and a first temperature sensor 23 are connected to form a control loop. The sub-controller can open or close the control loop connected to it.

[0091] It is understood that the refrigeration module 200 can be made into a cuboid, a rectangular parallelepiped or other shapes according to the needs. In the present application, in order to facilitate the manufacture and installation, the refrigeration module 200 is set in a rectangular shape. The cooling channel can be staggered and extended in the refrigeration block 21 to increase the amount of refrigerant that can be passed into and cooled by the refrigeration module 200. The first temperature sensor 23 and the sub-controller can be a split structure, so as to facilitate the detection and maintenance of the first temperature sensor 23 and the controller. When one of the components is damaged, the other component can continue to be used in subsequent work to reduce losses and save costs. Of course, a first temperature sensor 23 can also be set as an integral part with a sub-controller to form a thermostat, which can have both the function of detecting temperature and the control function of controlling the connection or disconnection of the electrical circuit. The first temperature sensor 23 and the sub-controller are set as an integral part to facilitate the connection and installation of the various structural parts of the refrigeration module 200, and the space occupied by the installation can be reduced.

[0092] The refrigeration module 200 provided in the present application includes a refrigeration block 21, a heat exchange component 22, a first temperature sensor 23 and a controller. The refrigerant after completing the heat exchange can flow from the inlet of the refrigeration block 21 into the cooling channel inside the refrigeration block 21, so as to perform heat exchange with the heat exchange component 22 through the refrigeration block 21 to reduce the temperature of the refrigerant, thereby ensuring that the cooled refrigerant can be discharged from the outlet of the refrigeration block 21 for continued recycling, thereby improving the utilization efficiency of the refrigerant and reducing costs.

[0093] In addition, the refrigeration module 200 provided in the present application can improve the heat exchange effect and efficiency of the refrigeration block 21 by arranging multiple heat exchange components 22 on the outer surface of the refrigeration block 21. The first temperature sensor 23 connected to the heat exchange component 22 can be used to monitor the temperature of the heat exchange component 22. When the temperature of the heat exchange component 22 is abnormal, the sub-controller connected to the heat exchange component 22 and the first temperature sensor 23 can disconnect the power supply to isolate the heat exchanger, so that the refrigeration module 200 provided in the present guarantee application can still work normally under the condition that some heat exchange components 22 fail, thereby reducing the failure rate of the refrigeration module 200 and improving the reliability of the refrigeration module 200.

[0094] It can be understood that the positions of the inlet and the outlet can be set on any side of the refrigeration block 21 according to the needs. For example, in order to ensure the balance of the structure of the refrigeration module 200, the inlet and the outlet can be set on opposite sides of the refrigeration block 21. Of course, in order to facilitate the installation of each structure of the refrigeration module 200 and to facilitate the placement of the refrigeration module 200, the inlet and the outlet can be set on the same side of the refrigeration block 21. In order to facilitate the refrigeration block 21 to communicate with other structures to form a refrigerant passage, the refrigeration module 200 can also include an inlet pipe 27 and an outlet pipe 28, the inlet pipe 27 is connected to the inlet, and the outlet pipe 28 is connected to the outlet. The inlet pipe 27 and the outlet pipe 28 can be detachably connected to the refrigeration block 21, for example, directly connected by threaded connection or plug-in, or connected by an adapter. Of course, in other embodiments, the inlet pipe 27 and the outlet pipe 28 can also be an integral structure with the refrigeration block 21 to reduce the installation steps of the refrigeration module 200 and simplify the assembly process of the refrigeration module 200. The liquid inlet pipe 27 and the liquid outlet pipe 28 may also be integrally formed with the refrigeration block 21, and the connection strength and sealing between the inlet and the liquid inlet pipe 27, and between the outlet and the liquid outlet pipe 28 may be enhanced to prevent leakage of the refrigerant.

[0095] Reference Figure 7 In an embodiment of the present application, it is defined that the refrigeration block 21 has a mounting surface, the direction surrounding the mounting surface is the circumferential direction, and the plurality of heat exchange components 22 are symmetrically arranged on two opposite sides of the refrigeration block 21 in the circumferential direction.

[0096] It can be understood that the placement surface is the surface of the refrigeration block 21 facing the surface for placing the refrigeration module 200. In order to further increase the cooling channel and increase the amount of refrigerant that can be introduced, the inlet and outlet can be set on the surface of the refrigeration block 21 away from the placement surface. The heat exchange components 22 are symmetrically arranged on the two opposite sides of the refrigeration block 21 in the circumferential direction, so that the refrigeration block 21 can simultaneously perform heat exchange on the opposite sides of the refrigerant in the cooling channel, so as to improve the heat exchange efficiency of the refrigeration module 200, ensure that the refrigerant passing through various parts of the cooling channel can be evenly cooled, avoid the situation where the refrigerant is partially cooled and partially not cooled, thereby improving the cooling effect of the refrigeration module 200.

[0097] Reference Figure 6 In an embodiment of the present application, the direction perpendicular to the placement surface is defined as the height direction, and the multiple heat exchange components 22 provided in the refrigeration block 21 are arranged at intervals along the height direction.

[0098] It can be understood that the refrigeration fin 222 can be provided with a first connection line 2221 for connecting to the controller, and the first temperature sensor 23 can be provided with a second connection line 231 for connecting to the controller. A plurality of heat exchange components 22 can be provided on each of the two opposite sides of the refrigeration fin 222 in the circumferential direction to improve the reliability of the cooling work of the refrigeration module 200. The spacing of the plurality of heat exchange components 22 is conducive to the installation of each heat exchange component 22, and can avoid mutual interference between the heat exchange components 22. When the plurality of heat exchange components 22 are spaced in the height direction, the cooling channel can be extended or arranged in the height direction to increase the cooling range and cooling amount of the refrigeration module 200, thereby improving the cooling capacity of the refrigeration module 200.

[0099] Reference Figure 7 In an embodiment of the present application, the heat exchange component 22 includes a fin structure 221 and a refrigeration fin 222. The fin structure 221 includes a base 2211 and a plate body 2212. The base 2211 is connected to the refrigeration block 21. The plate body 2212 is connected to a side of the base 2211 away from the refrigeration block 21. The refrigeration fin 222 is arranged between the refrigeration block 21 and the base 2211.

[0100] It can be understood that the refrigeration fin 222 has a cold end and a hot end, the cold end of the refrigeration fin 222 is arranged toward the refrigeration block 21, and the hot end is arranged toward the fin structure 221. The cold end of the refrigeration fin 222 can absorb the heat of the refrigeration block 21 to transfer the heat to the hot end, and then transfer it to the fin structure 221 for heat dissipation, so as to achieve heat exchange between the refrigeration block 21 and the heat exchange module. The base 2211 provided with the fin structure 221 can receive and dissipate the heat of the hot end of the refrigeration fin 222, and facilitate the installation of the fin structure 221. The sheet body 2212 provided on the side of the base 2211 away from the refrigeration fin 222 can increase the surface area of ​​the fin structure 221 to improve the heat dissipation capacity of the fin structure 221. In order to improve the heat conduction effect between the base 2211 and the sheet body 2212, the base 2211 and the sheet body 2212 can be set as an integral structure.

[0101] Reference Fig. 9 In order to further increase the heat dissipation area of ​​the fin structure 221 and improve the heat dissipation capacity and heat dissipation effect of the fin structure 221, a plurality of fins 2212 may be provided, and the plurality of fins 2212 are connected to the side of the base 2211 away from the refrigeration block 21 at intervals.

[0102] Reference Fig. 9 In order to further improve the heat dissipation effect of the fin structure 221 under the same volume, the sheet body 2212 can be arranged in a wave shape, thereby further increasing the heat dissipation area of ​​the fin structure 221 and enhancing the heat dissipation capacity of the fin structure 221. It can be understood that the wave shape can be formed by multiple rectangles, multiple arcs, multiple triangles or other shapes.

[0103] The refrigeration module in the related art mainly uses a fan to blow air to the radiator to force the refrigeration fins to dissipate heat. This type of refrigeration module usually cannot meet the refrigeration temperature requirements under high temperature conditions. When the refrigeration module in the related art dissipates heat, the heat emitted by the radiator is likely to affect the cold end of the refrigeration fin, resulting in poor heat exchange effect of the refrigeration fin and reducing the cooling effect of the refrigeration module. Based on the structure of the refrigeration module in the related art, if you want to achieve better refrigeration performance, you need to invest more cost and occupy more space.

[0104] Reference Figure 7 In an embodiment of the present application, the refrigeration module 200 further includes a first thermal insulation layer 24 , and the first thermal insulation layer 24 is disposed between the refrigeration block 21 and the heat exchange component 22 .

[0105] It can be understood that the first insulation layer 24 arranged between the refrigeration block 21 and the heat exchange component 22 can insulate the surrounding area of ​​the refrigeration fin 222 to prevent the heat dissipated by the fin structure 221 from being dissipated to the cold end of the refrigeration fin 222 and affecting the heat exchange effect of the refrigeration fin 222.

[0106] See also Figure 8In an embodiment of the present application, the first insulation layer 24 includes an insulation foam 241, a plastic insulation block 242 and a non-thermal conductive potting glue 243. The insulation foam 241 is sandwiched between the refrigeration block 21 and the plastic insulation block 242. The fin structure 221 is installed on the side of the plastic insulation block 242 away from the insulation foam 241. At least part of the structure of the refrigeration plate 222 protrudes from the surface of the plastic insulation block 242 away from the insulation foam 241 and abuts against the base 2211. The non-thermal conductive potting glue 243 fills the gap between the plastic insulation block 242 and the fin structure 221.

[0107] It can be understood that the heat-insulating foam 241 and the plastic insulation block 242 are coated on the outer side of the refrigeration block to isolate the refrigeration block 21 from the fin structure 221, thereby preventing the heat emitted by the fin structure 221 from directly exchanging heat with the refrigeration block 21 and affecting the cooling effect of the refrigerant in the refrigeration block 21. The two-layer insulation structure improves the heat-insulating effect between the refrigeration block 21 and the fin structure 221, and the setting of the plastic insulation block 242 facilitates the installation and fixation of the fin structure 221. The fin structure 221 can be installed on the plastic insulation block 242 by means of snap-on or screw connection. At least part of the structure of the refrigeration fin 222 is protruded from the surface of the plastic insulation block 242 away from the heat-insulating foam 241, which can ensure the abutting contact effect between the base 2211 and the hot end of the refrigeration fin 222.

[0108] In order to improve the heat exchange effect of the cooling fin 222, the heat insulating foam 241 and the plastic insulation block 242 may be provided with an installation groove for installing the cooling fin 222, and the installation groove may penetrate the heat insulating foam 241 and the plastic insulation block 242. The cooling fin 222 may be arranged in the installation groove so that the cold end of the cooling fin 222 can abut or abut against the surface of the cooling block 21. Of course, in other embodiments, see Figure 3 In order to avoid the limitation caused by the thickness of the cooling sheet 222, and to increase the thickness of the heat insulation foam 241 and the plastic insulation block 242 to improve the heat insulation effect, the installation groove can be used for inserting a part of the structure of the cooling block 21, so that the part of the structure of the cooling block 21 inserted into the installation groove can abut against the cold end of the cooling sheet 222. In order to ensure the abutting contact strength between the cooling sheet 222 and the base 2211 and improve the heat exchange effect between the base 2211 and the hot end of the cooling sheet 222, the part of the structure of the cooling block 21 inserted into the installation groove can be exposed on the surface of the plastic insulation block 242 away from the heat insulation foam 241, or can also be flush with the surface of the plastic insulation block 242 away from the heat insulation foam 241, so that the cooling sheet 222 can be completely protruded on the side of the plastic insulation block 242 away from the heat insulation foam 241. The cooling block 21 can be formed with a limiting groove for limiting and fixing the cooling sheet 222 to enhance the reliability of the abutting contact between the cooling sheet 222 and the cooling block 21.

[0109] A non-thermally conductive potting glue 243 is filled between the refrigeration block 21 and the fin structure 221, so that the non-thermally conductive potting glue 243 can be filled in the gaps between the refrigeration block 21 and the fin structure 221 to prevent the heat on the fin structure 221 from being transferred to the cold end of the refrigeration fin 222, thereby affecting the refrigeration fin 222 or the heat conduction efficiency, and preventing the heat on the fin structure 221 from being transferred to the refrigeration block 21, thereby affecting the refrigeration performance of the refrigeration module 200. Filling the non-thermally conductive potting glue 243 can also prevent the water vapor in the air from condensing on the refrigeration fin 222 to form condensed water, thereby preventing the condensed water from causing the refrigeration fin 222 to fail. The refrigeration module 200 provided in the present application can be triple-protected by the first thermal insulation layer 24, thereby preventing the heat on the fin structure 221 from being transferred to the refrigeration block 21 or the cold end of the refrigeration fin 222, thereby affecting the refrigeration performance of the refrigeration module 200.

[0110] Reference Figure 6 In an embodiment of the present application, the refrigeration block 21 further includes a second thermal insulation layer 25 , and the second thermal insulation layer 25 is coated on each side of the refrigeration block 21 that is not connected to the heat exchange component 22 .

[0111] It is understandable that the second insulation layer 25 can be a plastic insulation block 242 to facilitate the installation and placement of the refrigeration module 200.
