Abstract

The invention belongs to the technical field of nucleic acid amplification instruments, and particularly relates to a fan module of a digital nucleic acid amplification instrument. The fan module comprises a fan module frame, heat sinks and cooling fins, wherein the fan module further comprises a variable speed fan, a temperature sensor, a temperature controller and a fan speed controller. The variable speed fan, the temperature sensor, the temperature controller and the fan speed controller are electrically connected to each other. The variable speed fan speed and the chip temperature have aone-to-one correspondence relationship. The variable speed fan speed can be adjusted in real time according to the chip temperature, so that the heat dissipation is fast and the heat dissipation process is controlled. The PID algorithm can be combined to accurately control the temperature, and the temperature overshoot is not prone to occur.

Description

technical field [0001] The invention relates to the technical field of nucleic acid amplification instruments, in particular to a fan module of a digital nucleic acid amplification instrument. Background technique [0002] Nucleic acid amplification instrument is a gene analysis instrument, which specifically refers to the use of nucleic acid amplification technology to amplify and synthesize a specific gene to be tested in vitro to achieve gene amplification and then perform gene analysis on DNA. Nucleic acid amplification technology, that is, PCR (polymerase chain reaction, Polymerase Chain Reaction) amplification technology, this technology simulates the natural replication process of DNA in organisms, the specific process includes: the first step, DNA denaturation (94°C), The hydrogen bond of the double-stranded DNA template is broken under the action of heat to form a single-stranded DNA; the second step is annealing (55°C), the temperature of the system is lowered, and...
