[0046] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0049] In addition, the description involving "first", "second" and the like in the present application is only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first", "second" can explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing throughout the text is to include three parallel schemes, for example, "A and / or B" includes A scheme, or B scheme, or A and B schemes are satisfied at the same time. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of ordinary skilled in the art, when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, nor within the scope of protection required by the present application.

[0050] In the in-vitro diagnostic industry, in order to measure relevant clinical parameters, different reagents are usually added to the sample for reaction, and then corresponding measurement is carried out, and some of the reagents contain volatile substances. In order to prolong the opening effective period of the reagent, the storage temperature of the reagent is usually reduced, so as to reduce the diffusion movement of the volatile substances in the reagent, and finally achieve the purpose of prolonging the opening effective period.

[0051] For example, when detecting C-reactive protein, a latex reagent containing volatile substances needs to be used. Currently, manufacturers basically design corresponding refrigeration modules to refrigerate the reagent at 2-8°C, for example, by setting a refrigeration chamber, cooling the refrigeration chamber, and storing the reagent in the refrigeration chamber. In the refrigerated state, since the corresponding sampling structure or pipeline needs to draw reagent from the reagent bottle, there is inevitably a channel for the refrigeration chamber to contact with the outside air, and therefore condensate water is generated in the refrigeration chamber. The condensate water is usually a difficult problem to handle. Some manufacturers design a corresponding condensate water collection structure and then guide it to the outside of the machine and flow into the instrument installation table. Some solutions do not process the cold water, and when the customer replaces the reagent, corresponding condensate water will flow from the refrigeration chamber to the inside of the instrument. The above methods cause poor user experience for customers.

[0052] To solve the above problems, the application provides a refrigeration device 100 for refrigerating reagents, comprising a base body 10, a refrigeration mechanism 30, and a refrigeration chamber 50. The refrigeration mechanism 30 is arranged on the base body 10, and the refrigeration mechanism 30 is formed with a liquid storage chamber 32. The refrigeration chamber 50 is arranged on the refrigeration mechanism 30, and the refrigeration chamber 50 is provided with a liquid passing channel 52. The liquid passing channel 52 is in communication with the liquid storage chamber 32, so that the liquid in the refrigeration chamber 50 is collected in the liquid storage chamber 32. The refrigeration chamber is used to place reagents.

[0053] The base body refers to a support structure, which can be a support frame or a support frame.

[0054] The refrigeration mechanism refers to a collection of structures capable of cooling, having a cold part and a hot part. The cold part has a low temperature and is used to absorb heat. The hot part has a high temperature, for example, the cold part is arranged at the part that needs to be cooled, and the cold part absorbs the heat of the part that needs to be cooled, so that the temperature of the part that needs to be cooled is reduced.

[0055] The refrigeration chamber refers to a container capable of containing objects, for example, the container has an opening at the top for objects to be placed inside the container. It can be understood that in order to facilitate the refrigeration mechanism to absorb the heat of the container and cool it to maintain a refrigerated environment, the material of the container can be a heat-conducting metal material. The good heat conductivity of the metal helps the refrigeration mechanism to absorb its heat, for example, it can be an aluminum alloy or copper. At the same time, in order to maintain the low-temperature effect of the container, the container is also provided with a heat preservation layer.

[0056] The liquid storage chamber refers to a storage space for storing solutions.

[0057] The liquid passing channel refers to a channel through which liquid can pass.

[0058] The liquid passing channel is in communication with the liquid storage chamber, which means that the liquid passing through the liquid passing channel can flow into the liquid storage chamber.

[0059] As Figures 2 to 4As shown, the base 10 plays a supporting role for supporting the refrigeration mechanism 30, which is used to reduce the temperature of the refrigeration chamber 50 and keep the refrigeration chamber 50 at a certain storage temperature suitable for storing reagents. Considering that the refrigeration chamber 50 will generate condensed liquid, in order to facilitate the collection and storage of the condensed liquid, the refrigeration mechanism 30 is formed with a liquid storage chamber 32, and the refrigeration chamber 50 is provided with a liquid passage 52 that communicates with the liquid storage chamber 32. The condensed liquid generated by the refrigeration chamber 50 can be effectively collected into the liquid storage chamber 32, on the one hand to avoid the condensed liquid overflowing everywhere and affecting the user experience, and on the other hand to set the liquid storage chamber 32 on the refrigeration mechanism 30, so that the condensed water collected into the liquid storage chamber 32 can be used to dissipate the heat generated during the refrigeration process of the refrigeration mechanism 30, thereby improving the heat dissipation effect of the refrigeration mechanism 30.

[0060] Further, the refrigeration mechanism 30 includes a refrigeration assembly 31 and a heat insulation assembly 33. The refrigeration assembly 31 includes a heat sink 311 and a refrigeration module 313 arranged on the heat sink 311. The heat sink 311 is formed with a liquid storage groove 310. The heat insulation assembly 33 is arranged on the heat sink 311 and covers the liquid storage groove 310 to form the liquid storage chamber 32.

[0061] The refrigeration assembly refers to a device capable of cooling.

[0062] The heat insulation assembly has a heat insulation effect.

[0063] The refrigeration module refers to an element capable of cooling, for example, a semiconductor refrigeration piece. The principle is that when a direct current passes through an electric couple composed of two different semiconductor materials in series, heat can be absorbed and released at both ends of the electric couple, respectively, so that the purpose of refrigeration can be achieved.

[0064] The heat sink refers to a device for dissipating heat, for example, a semiconductor refrigeration piece including a cold end and a hot end. The cold end of the semiconductor refrigeration piece is directly fixed to the bottom of the refrigeration chamber. The hot end of the refrigeration piece is cooled by air or water.

[0065] As shown in Figure 2 The refrigeration mechanism 30 includes a refrigeration assembly 31 and a heat insulation assembly 33. The heat insulation assembly 33 is arranged on the refrigeration assembly 31. The refrigeration assembly 31 includes a heat sink 311 and a refrigeration module 313 arranged on the heat sink 311. The refrigeration module 313 is used to create a low-temperature environment and simultaneously generate heat. The generated heat is transferred to the heat sink 311 for cooling.

[0066] The heat sink 311 is formed with a liquid storage groove 310, and the heat insulation assembly 33 is arranged on the heat sink 311, and the heat insulation assembly 33 covers the liquid storage groove 310 to form the liquid storage chamber 32. That is, at least part of the chamber wall of the liquid storage chamber 32 is formed by the heat sink 311, and at least another part of the chamber wall is formed by the heat insulation assembly 33. The heat sink 311 itself is used to cool the refrigeration module 313. By forming the liquid storage groove 310 on the heat sink 311, the condensed liquid is stored in the liquid storage groove 310, which can effectively utilize the condensed liquid to cool the heat sink 311, further reduce the temperature of the heat sink 311, improve the cooling efficiency of the heat sink 311 for the refrigeration module 313, and improve the heat dissipation speed of the refrigeration module 313, thereby improving the refrigeration efficiency of the refrigeration module 313, and being beneficial to maintaining the refrigeration temperature of the refrigeration chamber.

[0067] At the same time, at least another part of the chamber wall of the liquid storage chamber 32 is formed by the heat insulation assembly 33, and the condensed water can also cool the heat insulation assembly 33 to improve the heat insulation effect of the heat insulation assembly 33.

[0068] Further, the heat sink 313 includes a hot end structure 3111 and a cold end structure 3113 connected with each other, the liquid storage groove 310 is formed on the cold end structure 3113, and the refrigeration module 313 is arranged on the hot end structure 3111; the heat insulation assembly 33 includes a covering part 331 and a supporting part 333 connected with each other, the covering part 331 is arranged on the cold end structure 3113 and surrounds the liquid storage groove 310 to form the liquid storage chamber 32, and the supporting part 333 is arranged on the hot end structure 3111 and surrounds the refrigeration module 313, and the refrigeration chamber 50 is arranged on the supporting part 333 and opposite to the refrigeration module 313.

[0069] The hot end structure is a part used to contact the hot end of the refrigeration module 313. Since the hot end of the refrigeration module 313 is arranged at this part, this part absorbs the heat of the hot end of the refrigeration module 313, so that the temperature of this part is increased.

[0070] The cold end structure is a part not contacting the hot end of the refrigeration module 313. The temperature of the cold end structure is lower than that of the hot end structure, and the cold end structure is used to dissipate heat and cool the hot end structure.

[0071] The supporting part is used to play a supporting role.

[0072] The covering part is used to play a sealing role.

[0073] For example, Figure 2 and Figure 6As shown, in order to facilitate the cooling of the refrigeration module 313 by the heat sink 313, the heat sink 313 includes a hot end structure 3111 and a cold end structure 3113. The cooling module 313 is disposed on the hot end structure 3111. The heat generated by the cooling module 313 is transferred to the hot end structure 3111. The cold end structure 3113 is used to cool the hot end structure 3111. A liquid storage groove 310 is formed on the cold end structure 3113. The condensate can cool the cold end structure 3113, increase the temperature difference between the cold end structure 3113 and the hot end structure 3111, and improve the cooling efficiency of the hot end structure 3111.

[0074] like Figure 2 and Figure 5 As shown, the heat insulation component 33 includes a cover portion 331 and a support portion 333. The cover portion 331 is disposed on the cold end structure 3113 and surrounds the liquid storage groove 310 to form a liquid storage chamber 32. The cover portion 331 covers the cold end structure 3113, which on the one hand protects the liquid storage groove 310, and on the other hand, the cover portion 331 can act as a heat insulation plate to prevent the low temperature of the cold end structure 3113 from being conducted out from the location of the cover portion 331, so that the low temperature of the cold end structure 3113 is concentrated and conducted to the hot end structure 3111, making full use of the cooling of the cold end structure 3113.

[0075] Meanwhile, the support part 333 is located on the hot end structure 3111 and surrounds the refrigeration module 313. That is, the hot end structure 3111 is used as a support surface, so that the refrigerator compartment 50 is located on the support part 333, and the refrigerator compartment 50 and the refrigeration module 313 are arranged opposite to each other. Considering that the refrigerator compartment 50 needs to carry reagents and is relatively heavy, the hot end structure 3111 is used as a stable support to form a better support and avoid the heavy weight of the refrigerator compartment 50 directly pressing on the refrigeration module 313 and affecting the function of the refrigeration module 313. At the same time, in order to make the refrigerator compartment 50 close to the refrigeration module 313 so as to facilitate the refrigeration module 313 to cool the refrigerator compartment 50, the refrigerator compartment 50 and the refrigeration module 313 are arranged opposite to each other. It can be understood that the refrigerator compartment 50 and the refrigeration module 313 can be in direct contact, but they can also not be in direct contact as needed. No specific limitation is made.

[0076] Furthermore, the support 333 has a recessed mounting groove 3331 on the side facing away from the hot end structure 3111. A connecting opening 3330 is opened at the bottom of the mounting groove 3331, and the refrigerator compartment 50 is located in the mounting groove 3331. The bottom of the refrigerator compartment 50 and the side wall 3330a of the connecting opening 3330 form an installation space 3332, and the refrigeration module 313 is housed in the installation space 3332.

[0077] like Figure 5As shown, in order to facilitate the installation of the refrigeration chamber 50, the side of the support portion 333 away from the hot end structure 3111 is recessed to form an installation groove 3331, and the refrigeration chamber 50 is arranged in the installation groove 3331, that is, the refrigeration chamber 50 is limited in the installation groove 3331, thereby improving the installation stability of the refrigeration chamber 50. At the same time, in order to facilitate the refrigeration chamber 50 to contact the refrigeration module 313, a communication port 3330 is formed in the bottom of the installation groove 3331, and the bottom of the refrigeration chamber 50 and the side wall 3330a of the communication port 3330 form an installation space 3332, and the refrigeration module 313 is arranged in the installation space 3332, that is, the refrigeration module 313 directly contacts the bottom of the refrigeration chamber 50, thereby improving the cooling effect.

[0078] It can be understood that the cold end surface of the refrigeration module 313 is usually directly attached to the refrigeration chamber 50, and a small gap or unevenness therebetween is filled with a heat-conducting material.

[0079] Further, the side of the support portion 333 facing the hot end structure 3111 is protruded to form a limiting frame 3333, the side of the hot end structure 3111 facing the support portion 333 is protruded to form a bearing table 3111a, the refrigeration module 313 is arranged on the bearing table 3111a, and the limiting frame 3333 is sleeved on the bearing table 3111a; and the surface of the cold end structure 3113 is recessed to form a liquid storage groove 310 away from the cover portion 331.

[0080] As shown in Figure 5 and Figure 6 , in order to stably connect the heat insulation assembly 33 to the heat sink 313, as shown in Figure 5 , the side of the support portion 333 facing the hot end structure 3111 is protruded to form a limiting frame 3333, as shown in Figure 6 , the side of the hot end structure 3111 facing the support portion 333 is protruded to form a bearing table 3111a, and the refrigeration module 313 is arranged on the bearing table 3111a, as shown in Figure 2 , the limiting frame 3333 is sleeved on the bearing table 3111a, so that the heat insulation assembly 33 and the heat sink 313 are stably connected, and the limiting frame 3333, as a part of the heat insulation assembly 33, has a heat insulation function, which can prevent the heat generated by the heat sink 313 from being radiated from the position where the limiting frame 3333 is located to the environment around the refrigeration chamber 50.

[0081] At the same time, the protruding bearing table 3111a is used to arrange the refrigeration module 313, so as to facilitate the shortening of the distance between the refrigeration module 313 and the refrigeration chamber 50.

[0082] The surface of the cold end structure 3113 is recessed to form a liquid storage groove 310 away from the cover portion 331, thereby avoiding occupying the space of other parts and facilitating the compactness of the structure.

[0083] Further, the hot end structure 3111 is provided with a step 3335 at the periphery of the bearing platform 3111a, and the step 3335 is provided with the elastic member 20 between the support part 333; and / or, the cold end structure 3113 is provided with the first sealing member 40 between the cover part 331.

[0084] As shown in Figure 2 and Figure 6 , the refrigeration chamber 50 is arranged on the support part 333, the support part 333 is sleeved on the bearing platform 3111a, and the refrigeration module 313 is arranged on the bearing platform 3111a and located at the bottom of the refrigeration chamber 50. In order to improve the fit between the bottom of the refrigeration chamber 50 and the refrigeration module 313, and between the refrigeration module 313 and the bearing platform 3111a, the hot end structure 3111 is provided with a step 3335 at the periphery of the bearing platform 3111a, and the step 3335 is provided with the elastic member 20 between the support part 333. Since the support part 333 is connected to the hot end structure 3111 by screws, the distance between the support part 333 and the hot end structure 3111 can be adjusted by adjusting the tightness of the screws, that is, the hot end of the refrigeration module 313 is elastically pressed on the hot end structure 3111 by controlling the locking torque of the screws.

[0085] Further, the cold end structure 3113 is provided with the first sealing member 40 between the cover part 331, as shown in Figure 2 , in order to ensure the sealing of the liquid storage chamber 32, the cold end structure 3113 is provided with the first sealing member 40 between the cover part 331, that is, the installation gap of the first sealing member 40 is formed between the cold end structure 3113 and the cover part 331.

[0086] Further, the heat insulation assembly 33 is provided with a wire slot 330 on the side away from the hot end structure 3111, so that the wire harness of the refrigeration module 313 can pass through. The wire slot 330 provided on the side of the heat insulation assembly 33 away from the hot end structure 3111 can effectively avoid the direct contact between the wire harness of the refrigeration module 313 and the hot end structure 3111, improve the stability of the wire harness, and avoid heat aging.

[0087] Further, the bottom of the mounting groove 3331 is provided with a positioning part 3331a, and the bottom of the refrigeration chamber 50 is provided with a mounting part 51, and the mounting part 51 is positioned on the positioning part 3313; the mounting part 51 is a positioning groove 511 opened in the bottom wall of the refrigeration chamber 50, the positioning groove 511 is communicated with the liquid passing channel 52, the positioning part 3331a is a protruding part 3331a1 protruding from the bottom of the mounting groove 3331, the protruding part 3331a1 is provided with a flow guide channel 3331a2, the flow guide channel 3331a2 is communicated with the liquid storage chamber 32, and the protruding part 3331a1 is inserted into the positioning groove 511, so that the flow guide channel 3331a2 is communicated with the liquid passing channel 52.

[0088] In order to stably communicate the refrigeration chamber 50 with the liquid storage chamber 32, as shown in Figure 5 the groove bottom of the mounting groove 3331 is provided with a positioning portion 3331a, as shown in Figure 7 the bottom of the refrigeration chamber 50 is provided with a mounting portion 51, the mounting portion 51 is positioned at the positioning portion 3331a, and thus the refrigeration chamber 50 is effectively positioned at the support portion 333.

[0089] Meanwhile, the mounting portion 51 is formed with a first communication portion in communication with the liquid passing channel 52, and the positioning portion 3331a is formed with a second communication portion in communication with the liquid storage chamber 32, the first communication portion is in communication with the second communication portion, and thus when the mounting portion 51 and the positioning portion 3331a are positioned and mounted, the liquid passing channel 52 and the liquid storage chamber 32 are simultaneously communicated, so that the condensed liquid in the refrigeration chamber 50 can be collected in the liquid storage chamber 32.

[0090] It can be understood that the structures of the first communication portion and the second communication portion are not limited, which can be a connecting pipe or a hole.

[0091] As shown in Figure 7 the mounting portion 51 is a positioning groove 511 opened in the bottom wall of the refrigeration chamber 50, and the positioning groove 511 is in communication with the liquid passing channel 52, as shown in Figure 5 the positioning portion 3331a is a protruding portion 3331a1 protruding from the groove bottom of the mounting groove 3331, the protruding portion 3331a1 is provided with a flow guide channel 3331a2, the flow guide channel 3331a2 is in communication with the liquid storage chamber 32, and the protruding portion 3331a1 is inserted into the positioning groove 511 so that the flow guide channel 3331a2 is communicated with the liquid passing channel 52.

[0092] It can be understood that, as shown in Figure 5 the positioning portion 3331a includes a protruding portion 3331a1 protruding from the groove bottom of the mounting groove 3331, and the second communication portion is a flow guide channel 3331a2 opened in the protruding portion 3331a1, and the flow guide channel 3331a2 is in communication with the liquid storage chamber 32.

[0093] As shown in Figure 7 the first communication portion includes a positioning groove 511 opened in the bottom wall of the refrigeration chamber 50, and the positioning groove 511 is in communication with the liquid passing channel 52, and the protruding portion 3331a1 is inserted into the positioning groove 511 so that the flow guide channel 3331a2 is communicated with the liquid passing channel 52.

[0094] Further, the groove bottom of the positioning groove 511 is provided with a first sealing groove 512, the first sealing groove 512 is provided with a second sealing member 60, the second sealing member 60 is provided with a through hole, and the through hole is communicated with the liquid passing channel 52 and the flow guide channel 3331b.

[0095] As shown in Figure 7 and Figure 4As shown, the bottom of the positioning groove 511 is provided with a first sealing groove 512, and the first sealing groove 512 is provided with a second sealing member 60, and the second sealing member 60 is provided with a through hole, and the through hole is connected with the liquid passage 52 and the flow guide passage 3313b, so that the second sealing member 60 is pressed in the gap between the end face of the protruding part 3331a1 and the positioning groove 511, avoiding the leakage of condensate from the gap.

[0096] And / or, the bottom of the refrigeration chamber 50 is formed with a groove 53 for accommodating the refrigeration assembly 31, and the bottom of the refrigeration chamber 50 is provided with a second sealing groove 531 on the groove wall of the groove 53, and the second sealing groove 531 is provided with a third sealing member 80 for sealing the side peripheral surface of the refrigeration assembly 31.

[0097] As shown, Figure 7 In order to facilitate the installation of the refrigeration assembly 31, the bottom of the refrigeration chamber 50 is formed with a groove 53 for accommodating the refrigeration assembly 31, and, as shown, Figure 7 And Figure 2 the bottom of the refrigeration chamber 50 is provided with a second sealing groove 531 on the groove wall of the groove 53, and the second sealing groove 531 is provided with a third sealing member 80 for sealing the side peripheral surface of the refrigeration assembly 31, it can be understood that the cold face and the hot face of the refrigeration assembly 31 are attached to the bottom of the refrigeration chamber 50, and the hot face is attached to the hot end structure 3111, and the third sealing member 80 is arranged around the side peripheral surface of the refrigeration assembly 31 to intercept between the hot face and the cold face, preventing heat transfer and local condensate from being generated, affecting the service life of the refrigeration assembly 31.

[0098] And / or, the bottom of the refrigeration chamber 50 is formed with a groove 53 for accommodating the refrigeration assembly 31, and the bottom of the refrigeration chamber 50 is provided with a second sealing groove 531 on the groove wall of the groove 53, and the second sealing groove 531 is provided with a third sealing member 80 for sealing the side peripheral surface of the refrigeration assembly 31.

[0099] The reagent 90 is installed in the refrigeration chamber 50, and when the refrigeration assembly 31 is working, the cold end of the refrigeration assembly 31 continuously absorbs heat from the refrigeration chamber 50, and then transfers to the hot end of the heat sink. The cold end of the heat sink has a fin structure, when the heat of the hot end is transferred to the fin of the cold end, the cold air blown in by the fan carries away the heat on the fin, thereby reducing the temperature of the fin of the cold end, and further reducing the temperature of the hot end, so that the refrigeration assembly 31 can continuously reduce the temperature of the refrigeration chamber until the target temperature is reached, and then the working power of the refrigeration assembly 31 is reduced by the control software, and then the refrigeration chamber is maintained within the target temperature range.

[0100] Because there is a gap between the reagent bottle and the refrigeration chamber, the gap is full of air, when the temperature difference between the refrigeration chamber and the air reaches a certain degree, the air will condense on the surface of the refrigeration chamber or the reagent bottle to produce dew, after a long time of accumulation, the dew will increase, when the adhesion between the dew and the reagent bottle or the refrigeration chamber is less than the gravity of the dew, the dew will flow down to form a water flow.

[0101] AsFigure 7 and Figure 8 As shown, since the supporting surface 58 of reagent 90 is higher than the collection channel 54, the water flow will be collected in the collection channel 54 of the cold storage compartment 50. Multiple collection channels 54 are interconnected, and the liquid flows through the collection channels 54 and reaches the liquid passage 52 via the guide channel 56. The guide channel 56 can also be a sloped surface with a certain gradient.

[0102] And / or, the angle between the axis of the liquid passage 52 and the bottom surface of the refrigerator compartment 50 is an obtuse angle.

[0103] like Figure 7 As shown, in order to facilitate the outflow of liquid, the angle between the axis of the liquid passage 52 and the bottom surface of the refrigerator compartment 50 is an obtuse angle, that is, the liquid passage 52 is an inclined flow channel to facilitate the outflow of liquid.

[0104] And / or, the passageway where the liquid passage 52 and the flow guide channel 3331a2 are located is provided with an opening and closing structure.

[0105] When the ambient temperature is high, the temperature difference between the target temperature of the refrigerator compartment 50 and the ambient temperature is large, resulting in more condensate. However, the temperature of the hot end structure 3111 and the cold end structure 3113 of the radiator 311 will also be higher, accelerating the evaporation rate of the condensate to match the rate of condensate production. To further limit the water vapor evaporated by the radiator 311 from entering the refrigerator compartment 50, an opening and closing structure can be installed in the passageway where the liquid passage 52 and the guide passage 3331a2 are located. This structure can be opened and closed at set times. For example, when the ambient temperature is high, the opening and closing structure can be closed to prevent the evaporated water vapor from re-entering the refrigerator compartment 50. When the ambient temperature is low, the opening and closing structure can be opened to drain the water from the refrigerator compartment 50 in a timely manner. For example, the opening and closing structure can be a solenoid valve, installed in the liquid passage 52 or the guide passage 3331a2.

[0106] And / or, the cold end structure 3113 is provided with a fan 70 on the side away from the heat insulation plate 33.

[0107] like Figure 2 As shown, the condensate storage space, liquid storage chamber 32, is located above the fan 70. In this case, the temperature of the cold end structure 3113 is low, such as... Figure 3 As shown, the temperature rise of the cold air blown in from the air inlet is not significant after passing the right end. When it blows over the left end of the radiator 311, it can carry away more heat from the left end. At the same time, since the left end is hot and the right end is cold, the heat on the left end will also be dispersed to a certain extent by the right end. The above combined effect improves the heat dissipation efficiency of the entire cooling component 31, while also solving the problems of disorderly condensate accumulation causing poor customer experience, or condensate flowing to other parts of the instrument and causing corresponding risks.

[0108] And / or, an exhaust port 320 is provided on the wall of the liquid storage chamber 32.

[0109] like Figure 5 As shown, in order to reduce the reflow of condensate into the cold storage chamber 50 after evaporation, an exhaust vent 320 is opened directly above the condensate storage space to discharge the evaporated air to other parts of the instrument.

[0110] And / or, the refrigerator compartment 50 is provided with an opening, the opening is provided with a cover 55, and the side circumferential surface of the refrigerator compartment 50 is provided with an insulation layer 57.

[0111] like Figure 2 As shown, the refrigerator compartment 50 has an opening, and a cover 55 is provided at the opening. The side circumference of the refrigerator compartment 50 is provided with an insulation layer 57. The cover 55 is also made of an insulation material. The specific material of the insulation layer 57 is not limited, as long as it can achieve the insulation effect.

[0112] like Figure 1 As shown, this application also provides an analyzer 200, which includes a housing 201, a main unit 202, a sampling area 203, and a refrigeration device 100 as described above, the refrigeration device 100 being disposed within the housing 201.

[0113] Since the refrigeration device 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0114] It is understood that a receiving groove is formed inside the housing 201, and a guide is provided in the receiving groove. For example, as a guide, a guide rod is connected to a support structure in the rack analyzer 200 for supporting function and is provided in the receiving groove. The refrigeration device 100 is movably disposed on the guide rod so that the refrigeration device 100 is movably installed in the receiving groove.

[0115] It is also understandable that the refrigeration device 100 has a door 204 on the side away from the receiving tank. The door 204 is used to cover the opening of the receiving tank. When it is necessary to change the reagent, hold the door 204 and pull the refrigeration device 100 out of the receiving tank. After the reagent is changed, push the refrigeration device 100 back into the receiving tank.

[0116] The refrigeration unit 100 is located on the side of the housing 201, and the housing 201 forms a heat dissipation area 205 on the lower side of the refrigeration unit, with the heat dissipation area 205 facing the hot end structure 3111. This facilitates the exhaust of hot air from the refrigeration unit 100.

[0117] like Figure 1 As shown, the analytical instrument 200 also includes an injector loading section 206 and an injector unloading section 207.

[0118] The preferred embodiments of the present application are shown and described above, but the patent scope of the present application is not limited thereto, and any equivalent structural transformation made under the inventive concept of the present application, or direct / indirect application in other related technical fields using the content of the present application specification and drawings are included in the patent protection scope of the present application.
