[0001] The utility model relates to the field of digital PCR instruments, in particular to a heat dissipation device based on a digital PCR instrument. Background Art

[0002] PCR instruments, full name polymerase chain reaction instruments, are mainly used in biotechnology and medical research, especially in DNA analysis and diagnosis. PCR instruments can amplify specific DNA sequences, that is, copy the target DNA sequence into tens of thousands of copies in a very short time, thereby producing sufficient DNA for further analysis and research. The main components of PCR instruments include temperature control systems, optical detection systems, electronic control systems and reaction systems, the latter including DNA templates, primers, nucleotides and DNA polymerase. PCR instruments vary according to their functions and designs. For example, real-time fluorescence quantitative PCR instruments can monitor the progress of PCR reactions in real time for quantitative analysis; gradient PCR instruments can run multiple annealing temperatures at one time, suitable for optimizing and screening the best annealing conditions; in situ PCR instruments are used for gene amplification at specific locations in cells. PCR instruments are widely used, including gene testing, genetic disease diagnosis, infectious disease diagnosis, drug development, food safety testing, criminology and environmental science.

[0003] For example, a Chinese patent with publication number CN211665101 U discloses a heat dissipation device for a PCR instrument, which includes an instrument body, a heat dissipation hole is opened on one side of the instrument body, and the heat dissipation hole is detachably covered with a dust-proof heat dissipation mechanism, and the dust-proof heat dissipation mechanism includes a rectangular shell covering the heat dissipation hole, the interior of the shell is a cavity, and the side wall of the shell facing the heat dissipation hole is an open structure, and a heat-conducting silicone sheet is arranged at the opening of the shell, and the heat-conducting silicone sheet can completely cover the heat dissipation hole, and a heat dissipation component for heat dissipation of the heat-conducting silicone sheet is arranged in the shell. The advantage of the utility model is that it reduces the possibility of external dust entering the interior of the PCR instrument through the heat dissipation hole.

[0004] Another example is a Chinese patent with publication number CN214115554U, which discloses a heat dissipation device for a PCR amplifier, including an amplifier body, the outer walls on both sides of the amplifier body are provided with a plurality of heat dissipation holes, and the outer walls on both sides of the amplifier body are fixedly connected with a gas hood, the top inner wall and the bottom inner wall of the gas hood are provided with a card slot, and the inner wall of the card slot is provided with a movable slot, the inner walls on both sides of the movable slot are provided with a limit slot, and the inner walls of the limit slot are slidably provided with a limit block, and the outer walls on the opposite side of the two limit blocks are fixedly connected with the same movable plate.
