Problems solved by technology

This device is used to enhance the heat dissipation effect, but the air box is used to ventilate the main body of the PCR instrument, which still cannot avoid the influence of the optical path after the air is heated during the detection process

Abstract

The invention relates to a heat dissipation structure of a PCR detector, and the heat dissipation structure comprises a lower shell and a detection shell; the lower shell and the detection shell are fixed in a buckle connection mode; the lower shell and the detection shell form a hollow cavity structure; the heat dissipation structure is provided with the structure of the lower shell, and the installation positions of a heat dissipation fan and an exhaust fan are designed in a combined mode; therefore, while internal heat dissipation of the detector is achieved, negative pressure is kept in the exciting light mechanism area and the air inlet area, hot air is prevented from flowing back to the exciting light mechanism area and the air inlet position, it is ensured that optical signals of the exciting light mechanism are not affected by the temperature of other mechanisms in the detector, stable transmission of the optical signals is ensured, and the detection result accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of PCR amplification, in particular to a heat dissipation structure and heat dissipation method of a PCR detector. Background technique [0002] The basic principle of PCR technology is similar to the natural replication process of DNA. Its specificity mainly depends on the oligonucleotide primers complementary to both ends of the target sequence. It consists of three basic reaction steps: denaturation-refolding-extension: Denaturation of DNA: After the template DNA is heated to about 93°C for a certain period of time, the double-stranded DNA of the template DNA or the double-stranded DNA formed by PCR amplification is dissociated to make it single-stranded so that it can be combined with the primer for the next round of reaction Preparation; followed by annealing (annealing) of the template DNA and primers: after the template DNA is heated and denatured into a single strand, the temperature drops to about 5...
