Background

At present, polymerase Chain Reaction (PCR) instruments and fluorescent quantitative PCR instruments are used to amplify DNA or RNA (i.e. copy DNA or RNA by thermal cycling); generally, a semiconductor refrigerator (TEC) is used for heating and cooling in a PCR instrument; the other side of the TEC is refrigerated when the TEC heats the PCR tube; when the TEC cools the PCR tube, the other surface of the TEC is heated, the heat is transferred to the radiator, and then the fan blows the aluminum alloy radiator to take away the heat of the aluminum alloy radiator, namely an air cooling mode.
