[0038] In biochemical detection instruments, the storage conditions of detection reagents are crucial to the accuracy and reliability of the detection results. It is usually necessary to ensure that the detection reagents are stored under refrigeration conditions of 2-8°C. Peltier (semiconductor refrigeration sheet) is gradually widely used in the field of biochemical detection instruments due to its small size and fast refrigeration speed. Specifically, based on the Peltier effect, heat is transferred from the cold end to the hot end through current driving, thereby achieving the purpose of refrigeration.

[0039] However, when the Peltier refrigeration module reaches the corresponding refrigeration power, it needs to dissipate at least twice the refrigeration amount. This causes the heat dissipation problem to become a key factor restricting the improvement of the Peltier refrigeration efficiency. In the prior art, the Peltier refrigeration module mostly uses air cooling and liquid cooling heat dissipation methods. However, these heat dissipation methods have some limitations, such as the air cooling heat dissipation method requiring a large radiator area and having low refrigeration efficiency; the liquid cooling heat dissipation method has a complex structure and high cost. Therefore, how to solve the heat dissipation problem of the Peltier refrigeration module while ensuring the refrigeration effect and improving the refrigeration efficiency has become a technical problem to be solved.

[0040] To solve the above problems, the present application provides a refrigeration equipment 100 applied to a reagent pot, as shown in Figure 1 and Figure 2 The refrigeration equipment 100 applied to the reagent pot includes a shell 110 for connecting with the reagent pot; the shell 110 is sequentially provided with an auxiliary refrigeration assembly 120, a refrigeration sheet 140 and a heat dissipation assembly 130 from one end connected with the reagent pot to the other end; the cold end face 141 of the refrigeration sheet 140 is arranged towards the inside of the reagent pot, and the auxiliary refrigeration assembly 120 is arranged close to the cold end face 141 for accelerating the cooling efficiency of the refrigeration sheet 140; the heat dissipation assembly 130 is arranged close to the hot end face 142 of the refrigeration sheet 140 for discharging the heat of the hot end face 142. By arranging the auxiliary refrigeration assembly 120 on the cold end face 141 of the Peltier refrigeration sheet 140, the cold quantity generated by the refrigeration sheet 140 can be quickly transferred to the inside of the reagent pot, thereby realizing more uniform and stable refrigeration effect. By arranging the heat dissipation assembly 130 on the hot end face 142 of the Peltier refrigeration sheet 140, the heat generated by the refrigeration sheet 140 can be efficiently transferred and discharged.

[0041] The present application optimizes the layout of the refrigeration auxiliary assembly 120 and the heat dissipation assembly 130, significantly improves the refrigeration efficiency and heat dissipation performance, realizes the compact design of the equipment, reduces the energy consumption, improves the stability and reliability of the equipment, and provides an efficient and stable refrigeration solution for the reagent pot.

[0042] Figure 2 The present application provides a refrigeration equipment 100 applied to a reagent pot, as shown in Figure 2 The internal components of the refrigeration equipment are arranged from top to bottom, as shown inFigure 1 and Figure 2 As shown, the auxiliary cooling assembly 120 includes a first fan 121 and cooling fins 122. The cooling fins 122 are connected to the cold end face 141 to increase the cold energy transfer area of ​​the cold end face 141. The first fan 121 is connected to the cooling fins 122 to transfer the cold energy on the cooling fins 122 to the inside of the reagent pot. This application significantly increases the cold energy transfer area of ​​the cold end face 141 by tightly connecting the cooling fins 122 to the cold end face 141 of the cooling element 140, ensuring that the cold energy can be efficiently transferred to the fin surface. The first fan 121 is connected to the cooling fins 122 to accelerate the flow of cold air, quickly transferring the cold energy on the fins to the inside of the reagent pot, achieving a precise and uniform cooling effect.

[0043] Continue as Figure 1 and Figure 2 As shown, the heat dissipation assembly 130 includes multiple heat dissipation fins 132 and a second fan 131. The second fan 131 is located at the end of the housing 110 away from the reagent pot, and the multiple heat dissipation fins 132 are located between the second fan 131 and the hot end face 142 of the cooling chip 140. The second fan 131 is used to output the heat from the hot end face 142 to the air outlet 111 of the housing 110 via the heat dissipation fins 132. This layout design enables the second fan 131 to efficiently conduct the heat generated by the hot end face 142 of the cooling chip 140 through the heat dissipation fins 132 and output it to the air outlet 111 of the housing 110, thereby achieving rapid and effective heat dissipation.

[0044] This application significantly increases the heat dissipation area and improves the heat dissipation efficiency of the cooling chip 140 through the arrangement of multiple heat dissipation fins 132. Simultaneously, placing the second fan 131 at the end of the housing 110 away from the reagent pot ensures that heat is quickly dissipated, preventing heat from flowing back to the reagent pot area, thus providing a more stable and reliable low-temperature environment for the reagent pot. This efficient heat dissipation design significantly improves the overall performance of the refrigeration equipment, ensuring the stability and reliability of the equipment during long-term operation.

[0045] To further optimize the heat dissipation airflow path, in one embodiment of this application, the air outlet 111 and the second fan 131 are respectively located on two adjacent surfaces of the housing 110. Figure 2 As shown, Figure 2As shown, the second fan 131 is located in the same plane as the hot end face 142 of the refrigeration fin 140, and the air outlet 111 is perpendicular to the hot end face 142 in vertical projection. This unique design enables the second fan 131 to efficiently expel the heat generated by the hot end face 142 through the heat dissipation fins 132 and directly guide it to the air outlet 111 of the shell 110, thereby achieving smooth flow of the heat dissipation airflow and avoiding heat accumulation inside the shell 110. Through this optimized design, the heat dissipation efficiency of the refrigeration equipment is further improved, while ensuring efficient operation of the refrigeration equipment in a compact space, providing a stable and reliable low-temperature environment for the reagent pot.

[0046] Further, as shown in Figure 2 , Figure 3 and Figure 4 , the heat dissipation assembly 130 further includes a bottom plate 133 fixedly connected with the refrigeration fin 140, and a plurality of heat dissipation fins 132 are vertically arranged along the bottom plate 133; the heat dissipation fins 132 form an avoidance opening 134 therebetween for avoiding the fixed connection between the bottom plate 133 and the refrigeration fin 140; the plurality of heat dissipation fins 132 are connected with the hot end face 142.

[0047] In order to enable the heat dissipation fins 132 in the heat dissipation assembly 130 to be closely connected with the hot end face 142 to increase heat transfer, the bottom plate 133 is fixedly connected with the refrigeration fin 140, which can be screw connection, welding or other reliable mechanical connection mode, and the plurality of heat dissipation fins 132 extend along the bottom plate 133 towards the second fan 131 and are arranged in the direction of the arrow in the figure. Taking screws as an example, it is considered that if the screw fixed connection place directly contacts with the fins, heat resistance may be formed at the fixed connection place, affecting the heat dissipation efficiency; and the fins are usually made of thin metal sheets, and direct application of external force at the mounting point may cause deformation or damage of the fins.

[0048] The avoidance opening 134 designed by the present application can reduce local heat at the screw place on the one hand, ensure uniform heat dissipation in each area of the heat dissipation, and improve the heat dissipation performance; on the other hand, it can protect the fin structure, prevent deformation and damage of the fins caused by external force during installation, and ensure the firmness and reliability of screw installation. In addition, the design of the heat dissipation fins 132 and the bottom part also optimizes the convenience of installation and maintenance.

[0049] Optionally, the plurality of heat dissipation fins 132 have different spacings therebetween. The heat dissipation area can be increased while avoiding air flow obstruction. Smaller fin spacing can increase the heat dissipation area, thereby enhancing the heat transfer efficiency. However, too small spacing will increase air flow resistance, which will reduce the heat dissipation effect. Therefore, by designing different spacings, the best balance point between heat dissipation efficiency and air resistance can be found.

[0050] In an embodiment of the present application, the refrigeration device further comprises an insulating and heat-insulating plate 135, which is located between the refrigeration fin 140 and the bottom plate 133. By setting the insulating and heat-insulating plate 135, the heat transfer between the cold end and the hot end of the refrigeration fin 140 is reduced, avoiding the loss of cold energy or the backflow of heat, thereby significantly improving the refrigeration efficiency and reducing the energy consumption. By forming a heat-insulating barrier around the refrigeration fin 140, the insulating and heat-insulating plate 135 further enhances the stability and reliability of the refrigeration device, ensuring that the inside of the reagent pot can maintain a precise and stable low-temperature environment.

[0051] As shown in Figure 1 and Figure 2 Since the area of the cold end surface 141 of the refrigeration fin 140 is relatively small, in order to maximize the increase in the area of the cold-guiding fin 122, in the present application, a plurality of cold-guiding fins 122 are arranged along the transverse length of the refrigeration fin 140, i.e. Figure 1 in the direction of the arrows. This layout significantly increases the heat exchange area by making full use of the limited space of the cold end surface 141, thereby more efficiently conducting the cold energy generated by the refrigeration fin 140 to the fin surface.

[0052] Among them, the first fan 121 is a supply fan, which is used to quickly transfer cold energy to the inside of the reagent pot; the second fan 131 is an exhaust fan, which can efficiently suck the heat generated by the hot end surface 142 of the refrigeration fin 140 through the heat dissipation fin 132 and discharge it to the outside of the shell 110, not only optimizing the heat dissipation airflow path and reducing the residence time of heat in the shell 110, but also avoiding the accumulation of hot air inside the device, thereby significantly improving the heat dissipation efficiency, and the exhaust mode of the second fan 131 can more effectively reduce the noise compared to the blowing or supply mode, further improving the stability and reliability of the device operation.

[0053] In an embodiment of the present application, since the Peltier refrigeration fin 140 reaches the corresponding refrigeration power, the heat dissipated by the hot end will indeed be significantly higher than the refrigeration capacity of the cold end, i.e. the total heat dissipated by the hot end surface 142 is usually twice or more than the refrigeration capacity, therefore, the number of second fans 131 is set to two, on the one hand, it can avoid the decrease of refrigeration efficiency caused by insufficient heat dissipation, on the other hand, it can optimize the heat dissipation path, ensure that the heat can be quickly transferred from the hot end surface 142 to the external environment, reduce the heat accumulation, and improve the heat dissipation efficiency.

[0054] Further, the refrigeration device 100 of the present application is also provided with a temperature sensor (not shown in the figure), which is arranged close to the cold end face 141 of the refrigeration fin 140 and is electrically connected with the control module, for monitoring the temperature change in real time, automatically adjusting the rotating speed of the first fan 121 and / or the second fan 131 according to the monitored temperature, and also being able to adjust the power of the refrigeration fin 140 according to the monitored temperature, so as to ensure that the internal temperature of the reagent pot is always kept within the set low temperature range (such as 2-8℃). In addition, the temperature sensor can automatically adjust the refrigeration power, thereby providing a stable and reliable refrigeration environment for the biochemical reagents.

[0055] According to another aspect of the embodiments of the present application, as shown in Figure 5 and Figure 6 , a reagent pot 200 is provided, which comprises the refrigeration device (hereinafter referred to as refrigeration device) applied to the reagent pot according to any one of the above.

[0056] In biochemical detection instruments, the reagent pot 200 usually needs to store multiple reagents, and different reagents are selected for detection by a rotatable reagent disc during detection. In the conventional design, the refrigeration fin 140 in the refrigeration device 100 is usually installed at the bottom of the reagent pot 200. Although this arrangement is convenient for installation and more directly acts on the inside of the reagent pot 200, the bottom-end arrangement of the refrigeration device 100 may limit the heat dissipation efficiency, because the heat generated by the hot end needs to be discharged through a longer path, which is easy to accumulate inside the reagent pot 200 or the refrigeration device 100, and the bottom-mounted Peltier refrigeration fin 140 may conflict with the rotating mechanism of the reagent disc, resulting in limited refrigeration effect.

[0057] To solve this problem, in an embodiment of the present application, please continue to refer to Figure 5 and Figure 6 , the reagent pot 200 comprises a shell 210, the shell 210 comprises a containing groove 211 and a mounting groove 212, the containing groove 211 is in communication with the mounting groove 212, the containing groove 211 is used for containing reagents, and the mounting groove 212 is used for cooperating with the shell 110 of the refrigeration device; wherein the mounting groove 212 is arranged vertically to the bottom surface of the containing groove 211.

[0058] The reagent pot 200 of the present application is provided with the mounting groove 212 and the containing groove 211, the mounting groove 212 is arranged vertically to the bottom surface of the containing groove 211, that is, the mounting groove 212 is located on the edge wall of the containing groove 211, the refrigeration device 100 is connected with the reagent pot 200 through the mounting groove 212, and the auxiliary refrigeration assembly 120 of the refrigeration device 100 is arranged towards the reagent pot 200.

[0059] Compared with the conventional scheme of arranging the refrigeration device 100 at the bottom of the reagent pot 200, the reagent pot 200 of the present application reduces the occupation of the refrigeration device 100 on the space at the bottom of the reagent pot 200 by arranging the refrigeration device 100 in the mounting groove 212 on the edge wall of the containing groove 211, thereby providing sufficient space for the rotating mechanism of the reagent disc and avoiding interference or conflict with the reagent disc rotating the reagent. At the same time, the length of the heat dissipation path is reduced. The miniaturization and compactness of the reagent pot 200 and the biochemical detection device are realized, and the heat dissipation efficiency and refrigeration effect are significantly improved.

[0060] In an embodiment of the present application, the reagent pot further comprises a cover 220 connected with the shell 210 and covering the containing groove 211; the cover 220 is provided with a first opening 221 for the liquid suction assembly to enter the containing groove 211 to suck the reagent.

[0061] In order to ensure the stability and safety of the reagent under refrigeration conditions, the reagent pot 200 needs to have good sealing performance to prevent moisture and impurities in the external air from entering, and to avoid evaporation or deterioration of the reagent. By providing the first opening 221 on the cover 220, the reagent needle can enter the inside of the reagent pot 200 through the first opening 221 to suck the corresponding reagent without affecting the sealing performance. The first opening 221 can also be provided with a sealing ring or silica gel material to further enhance the sealing performance of the reagent pot 200.

[0062] Further, the reagent pot 200 further comprises a heating plate 230 located on the side of the cover 220 facing the containing groove 211, and the heating plate 230 comprises a second opening 231 corresponding to the first opening 221.

[0063] When the inside of the reagent pot 200 is kept in a refrigeration environment of 2-8℃, condensation water is easily generated at the first opening 221 due to the temperature difference between cold and hot each time the liquid suction assembly takes the reagent. This not only destroys the storage conditions of the reagent, but also can cause problems such as the label of the reagent bottle being damped and falling off, the surface of the reagent bottle being iced, etc., thereby affecting the normal use of the reagent and possibly interfering with the accuracy and reliability of the detection results. To solve this problem, the present application provides a heating plate 230 below the cover 220 (facing the containing groove 211), which reduces the temperature difference between the surface temperature of the cover 220 and the external temperature of the reagent pot 200 by moderately heating the temperature of the cover 220, thereby effectively avoiding the formation of condensation water and ensuring the stability of the storage conditions of the reagent and the accuracy of the detection results.

[0064] It should be noted that the reagent pot 200 of the present application is a reagent storage container, which provides a stable low-temperature storage environment for reagents and can be widely applied to biochemical detection devices, including but not limited to fecal, blood and other detection devices.

[0065] The above merely provides the preferred embodiments of the present application, and is not intended to limit the present application in any form. The scope of protection of the present application should be determined by the scope of the claims. Although the present application has been disclosed with the preferred embodiments, the present application is not limited to the above.
