[0031] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings. It should be understood that the embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention. Moreover, the features of the embodiments of the present invention may be combined with each other unless there is a conflict.

[0032] like Figures 1-16 As shown, the present invention provides a reagent refrigerator, comprising a refrigeration device and a water cooling device arranged outside the refrigeration device and connected to the refrigeration device; the refrigeration device comprises a reagent pot 21 provided with a refrigeration cavity 211 and a pot cover 22 connected to the reagent pot 21; a cooling channel is provided inside the bottom of the reagent pot 21; the inlet 2311 of the cooling channel is connected to the liquid outlet 122 of the water cooling device; the outlet 2312 of the cooling channel is connected to the liquid inlet 121 of the water cooling device.

[0033] In this embodiment, a cooling channel is provided inside the bottom of the reagent pot 21, so that the refrigeration chamber 211 can be refrigerated and stored. The water cooling device can first cool the refrigeration liquid so that the liquid can flow into the cooling channel through the liquid outlet 122, and flow back to the water cooling device from the outlet 2312 through the liquid inlet 121, thereby realizing the circulation of the liquid. In addition, the water cooling device is arranged outside the refrigeration device, which overcomes the problems of complex structure and high maintenance cost of the refrigeration device caused by the traditional arrangement inside the refrigeration device. The present invention adopts water cooling, which is less noisy when practical and has a simpler structure than air cooling, and is more conducive to production.

[0034] In a specific embodiment, the reagent pot 21 includes a pot wall 24 with openings at both ends and a water-cooled plate 23; the water-cooled plate 23 and the pot cover 22 respectively block the openings at both ends of the pot wall 24, thereby forming the refrigeration chamber 211; the water-cooled plate 23 and the pot wall 24 are integrally formed, and the water-cooled plate 23 is directly processed on the bottom of the reagent pot 21, and the water-cooled plate 23 and the pot wall 24 can also be detachably connected; that is, the water-cooled plate 23 and the pot wall 24 are first independent, and the water-cooled plate 23 can be processed first to form a water-cooled plate 23 with a cooling channel, which can reduce the difficulty of processing the cooling channel, and then the water-cooled plate 23 is connected to the pot wall 24 by snapping, bonding or screwing. The pot wall 24 is assembled together, and the end surface of the water-cooled plate 23 facing the pot cover 22 is provided with a condensation channel 1; a drain port 233 connected to the cooling channel is provided in the condensation channel 1. During the cooling and preservation of the reagent, a certain amount of condensed water will be generated. If the condensed water is not effectively discharged at this time, the refrigeration load will be increased. Therefore, a condensation channel 1 is provided on the end surface of the water-cooled plate 23, so that the condensed water can be gathered through the condensation channel 1 and flow into the cooling channel from the drain port 233 for discharge. By connecting the drain port 233 with the cooling channel, there is no need to set up an additional channel connected to the outside world inside the refrigeration chamber 211, thereby reducing the complexity of the structure.

[0035] In a specific embodiment, the condensation flow channel 1 includes a straight condensation channel 2321 arranged on the end surface of the water-cooled plate 23 facing the pot cover 22 and one or more annular condensation channels 2322 arranged at intervals; the straight condensation channel 2321 is connected to each annular condensation channel 2322, and the straight condensation channel 2321 divides each annular condensation channel 2322 into two symmetrically arranged semi-circular shapes. In this embodiment, the annular condensation channel 2322 has an inclination, that is, relative to the horizontal plane, the height of the position close to the straight condensation channel 2321 increases toward the position away from the straight condensation channel 2321, thereby facilitating the condensation water to be gathered into the straight condensation channel, and the height of the straight condensation channel 2321 at the position of the drain outlet 233 is lower than other positions, thereby facilitating the condensation water in the straight condensation channel 2321 to be discharged into the cooling flow channel.

[0036] In a specific embodiment, the cooling channel includes an inlet channel 2313 connected to the inlet 2311 and an outlet channel 2314 connected to the outlet 2312; the end of the inlet channel 2313 away from the inlet 2311 is connected to the end of the outlet channel 2314 away from the outlet 2312; the inlet channel 2313 and the outlet channel 2314 are both spiral, and the inlet channel 2313 and the outlet channel 2314 are staggered; the end of the inlet channel 2313 away from the inlet 2311 and the end of the outlet channel 2314 away from the outlet 2312 are both located at the center of the spiral; through such an arrangement, the coolant can enter the inlet channel 2313 from the inlet 2311 and flow toward the spiral center of the inlet channel 2313, and then From the spiral center of the liquid outlet flow channel 2314 to the outlet 2312 flow channel away from the spiral center, the cooling effect is best when the coolant enters the water cooling device and enters the liquid inlet flow channel 2313. As the coolant flows, the heat is transferred with the refrigerated chamber 211, so the cooling effect gradually decreases. At this time, in the liquid inlet flow channel 2313, the temperature of the coolant from the inlet 2311 to the spiral center gradually increases, while in the liquid outlet flow channel 2314, the opposite is true, that is, from the spiral center to the outlet 2312, the coolant temperature gradually increases. Therefore, the liquid inlet flow channel 2313 and the liquid outlet flow channel 2314 are arranged at intervals, and the circulation position is set at the spiral center, which can effectively improve the temperature uniformity in the refrigerated chamber 211. After repeated practical use, the applicant found that this arrangement has the best cooling effect and the lowest energy consumption.

[0037] In a specific embodiment, the water-cooled plate 23 includes a plate body 234 and a plate cover body that cooperates with the plate body 234. The cooling channel is arranged between the plate body 234 and the half cover body 235. The liquid inlet channel 2313 and the liquid outlet channel 2314 are provided with a spoiler 2315. By providing the spoiler 2315, the plate body 234 and the plate cover can be supported while the cooling liquid can be disturbed, thereby improving the cooling effect.

[0038] In a specific embodiment, the end face of the water-cooling plate 23 away from the pot cover 22 is provided with a heat insulating member 25, and / or the pot wall 24 is covered with a heat insulating member 25, and / or the end face of the pot cover 22 facing the water-cooling plate 23 is provided with a heat insulating member 25. Optimally, the end face of the water-cooling plate 23 away from the pot cover 22, the end face of the pot cover 22 facing the water-cooling plate 23 and the outer surface of the pot wall 24 are all provided with a heat insulating member 25. The heat insulating member 25 can be heat insulating foam or other heat insulating materials. The heat insulating member 25 can reduce the heat exchange between the refrigeration cavity 211 and the outside, thereby reducing energy consumption and improving the preservation effect.

[0039] In a specific embodiment, the end surface of the pot cover 22 facing the water-cooling plate 23 is recessed in a direction away from the water-cooling plate 23 to form a accommodating groove 221. The thermal insulation component 25 arranged on the pot cover 22 includes an insulating body and an extension portion 251 extending from the insulating body into the refrigeration cavity 211. The outer diameter of the extension portion 251 is tangent to the interior of the refrigeration cavity 211. The outer diameter of the insulating body is larger than the inner diameter of the refrigeration cavity 211 and smaller than the outer diameter of the pot wall 24, so that the insulating component 25 can improve the thermal insulation effect of the refrigeration cavity 211.

[0040] In a specific embodiment, a diffusion component is provided at the middle position of the bottom of the refrigeration chamber 211; the diffusion component includes a diffusion fin 261 provided on the bottom of the reagent pot 21 and a diffusion fan 262 provided on the diffusion fin 261 and with an air outlet facing the diffusion fin 261.

[0042] In this embodiment, an upper refrigeration module 142 and a lower refrigeration module 143 are provided in the box body 11, so that the liquid in the corresponding refrigeration channel 1422 can be refrigerated by the upper refrigeration module 142 and the lower refrigeration module 143 respectively, which greatly improves the refrigeration efficiency. When one of the refrigeration modules fails, the other refrigeration module can still refrigerate normally, thereby ensuring that the reagent refrigerator can continue to operate and avoiding losses to users due to damage to the reagent refrigerator. Specifically, the external liquid flows into the water storage tank 13 through the liquid inlet 121 and is stored in the water storage tank 13. When refrigeration is needed, the liquid in the water storage tank 13 is discharged through the water outlet 1 32 flows into the corresponding refrigeration channel 1422 from the channel inlet 1423 of the upper refrigeration module 142 and the channel inlet 1423 of the lower refrigeration module 143 respectively, and in the process of the liquid flowing through the refrigeration channel 1422, the semiconductor chip 1427 is cooled, that is, the cold temperature generated by the semiconductor chip 1427 is conducted to the liquid in the refrigeration channel 1422 through the stable conduction fins, thereby achieving the effect of cooling the liquid, and then the liquid in the upper refrigeration module 142 and the lower refrigeration module 143 are respectively merged from the corresponding channel outlet 1426 and flow into the equipment to be cooled through the liquid outlet 122, thereby cooling the equipment to be cooled.

The filter 18 can be provided on the middle section of the liquid inlet pipe 171, or at one end of the liquid inlet pipe 171 close to the liquid inlet 121, or at one end of the liquid inlet pipe 171 close to the water inlet 131.

[0046] In a specific embodiment, the reagent refrigerator also includes a filter 18.
