An air-cooled reagent storage system of the present invention will be described in detail with reference to the accompanying drawings. The features of the following examples and embodiments may be combined with each other without conflict.

Referring to fig. 1 to 16, an air-cooled reagent storage system 100 connected to a refrigeration device for reagent refrigeration includes a refrigeration compartment mechanism 1 and a reagent compartment mechanism 2 assembled together. The refrigerating bin mechanism 1 comprises an upper bin cover 10 and a lower bin cover 11 which are assembled with each other.

The first and second assembling

portions

111 and 112 are provided with first and

The reagent bin mechanism 2 comprises a reagent bin 20 and a reagent tray assembly 4 which is arranged in the reagent bin 20 and used for holding a reagent to be cooled. The bottom wall 201 of the reagent chamber is provided with a second air inlet 202 assembled with the first air outlet 102 and a second air outlet 203 assembled with the first air inlet 101 to form an air circulation closed loop. According to the reagent refrigerating system, the refrigerating bin mechanism 1 is connected with the reagent bin mechanism 2, and the forced convection of the fan assembly is combined with the arrangement of the refrigerating assembly 3 and the reagent tray assembly 4 in the refrigerating bin mechanism 1, so that cold air circulates in a loop formed by the refrigerating bin and the reagent bin 20, and the double refrigerating effects of direct cooling and heat radiation refrigerating on the solid of the reagent in the reagent bin 20 are realized; the purpose of uniform refrigeration is achieved with lower cost, the freezing of condensed water in the reagent bin 20 can be avoided, and the later maintenance of the refrigeration assembly 3 is facilitated.

Specifically, the refrigerating bin mechanism 1 is rotatably connected with the reagent bin mechanism 2 through a rotating shaft 12. In the embodiment, the refrigeration assembly 3 is a semiconductor refrigeration assembly, and includes a fixing base 30 and a fixing plate 31 assembled together and provided with a receiving portion 32. The accommodating part 32 is internally provided with a semiconductor refrigeration sheet 33. The upper part of the semiconductor refrigeration sheet 33 is attached to the heat dissipation member 34, and the lower part of the semiconductor refrigeration sheet is attached to the water cooling block 35 and clamped tightly. In order to ensure the heat transfer efficiency, as a preferred embodiment, the cold surface of the semiconductor refrigeration sheet 33 is attached to the heat dissipation member 34, and the hot surface of the semiconductor refrigeration sheet 33 is attached to the water cooling block 35, so that the semiconductor refrigeration sheet 33 is clamped between the water cooling block 35 and the heat dissipation member 34.

In another embodiment, the arrangement of the water cooling block 35 is eliminated, the hot surface of the semiconductor cooling plate 33 is attached to the heat dissipation member 34, and the heat is dissipated by forced convection with the fan, but the heat dissipation efficiency of the forced convection heat dissipation with the fan is not as high as that of the water cooling heat dissipation, and the space volume occupied by the forced convection heat dissipation with the fan is larger.

The clamping pad made of rubber effectively ensures that the semiconductor refrigerating sheet 33 is tightly attached to the water cooling block 35 and the radiating piece 34, errors generated by processing and assembling are eliminated by the elasticity of the rubber, and the semiconductor refrigerating sheet is simple in structure and reliable in performance. The water cooling block 35 is connected to a water circulation loop to take away heat generated by the semiconductor refrigeration sheet 33 through water circulation, so that the refrigeration effect is ensured.

The upper bin cover 10 is provided with flow guide ribs 103 on wall surfaces on two sides of the first air outlet, and positioning pins 104 are symmetrically arranged right in front of and right behind the first air outlet.

A plurality of parallel radiating fins 340 are formed on the radiating member 34. The upper bin cover 10 is externally coated with a first heat-insulating layer 13, and the lower bin cover 11 is externally coated with a second heat-insulating layer 14. The heat conduction efficiency is improved by arranging the heat radiating fins 340; and the first heat-insulating layer 13 and the second heat-insulating layer 14 arranged on the refrigerating bin are used for carrying out heat-insulating treatment on the airflow loop.

The top end of the first wind-isolating rib 2061 and the top end of the second wind-isolating rib 208 are located on the same horizontal plane. When condensed water is generated in the reagent chamber 20, the liquid isolating rib 2021 is disposed on the bottom wall 201 to prevent the condensed water from entering the refrigerating chamber mechanism 1 through the second air outlet 203 along with the air flow. In order to reduce the heat exchange between the reagent bin and the outside, a third insulating layer 23 is coated outside the reagent bin 20. The side wall 205 of the reagent chamber 20 is provided with a transparent bar code window 24.
