In the above technical solution, the carrier block 132 is used for carrying samples and/or reagents that need to be stored at low temperature, the cooling element 120 transfers low temperature to the carrier 130 through contact with the carrier 130, so as to create a cooling environment for the samples and/or reagents, and the fins 134 are used for performing heat exchange on air around the cooling device 100, and the moisture in the air is condensed into droplets and then collected, so that the humidity of the air around the cooling device 100 is reduced, thereby effectively avoiding the condensed water generated on the surface of the cooling device 100, reducing the risk of sample or reagent pollution, and further improving the accuracy of detection operation.

In this embodiment, the number of the fins 134 is two, and the fins are respectively connected to two sides of the carrier block 132. Of course, in other embodiments of the present utility model, the number of fins 134 may be one, three, four, etc., specifically, the fins 134 may be disposed on one side or multiple sides of the carrier block 132, or multiple fins 134 may be disposed on the same side of the carrier block 132, where the specific number and connection positions are not limited herein.

Specifically, the support block 132 is typically used to support a PCR plate of the prior art, which is a support that is mainly used as a primer, taq DNA polymerase, dNTP, template nucleic acid, mg, buffer, etc. involved in an amplification reaction in a polymerase chain reaction (Polymerase Chain Reaction, PCR).

And by arranging the condensation holes 1343, the condensed water generated by heat exchange on the first extension section 1341 and the second extension section 1342 is convenient to pass through the condensation holes 1343 and separate from the fins 134, so that the condensed water is prevented from being gathered on the fins 134 and then flows to the bearing blocks 132.

The heat generated by the refrigerating unit 120 is dissipated by the heat dissipating unit 150, so as to ensure that the cold storage device 100 is in a temperature range where stable operation is possible. Specifically, the heat dissipation frame 152 is internally provided with heat dissipation fins, and the heat dissipation fan 156 is arranged below the heat dissipation frame, so that the heat dissipation efficiency is improved by increasing the air flow inside the heat dissipation frame.

The cold storage device 100 with dehumidifying function further comprises a cover 110 and a base 140 in sliding fit, the bearing block 132 penetrates through the base 140, the base 140 is located on the upper side of the refrigerating element 120, and the cover 110 and the base 140 surround to form a containing cavity capable of containing the bearing element 130.
