Thermal module for biochemical reaction

Abstract

The invention provides a thermal module for biochemical reaction. The thermal module is characterized in that a semiconductor heating-cooling fin is arranged on the bottom surface of a pedestal, wherein a thermal interface material layer is arranged between the top surface of the semiconductor heating-cooling fin and the bottom surface of the pedestal, a soaking plate is arranged on the bottom surface of the semiconductor heating-cooling fin, a thermal interface material layer is arranged between the bottom surface of the semiconductor heating-cooling fin and the top surface of the soaking plate, and the bottom surface of the soaking plate is mounted on cooling fins; a soaking plate temperature-equalizing cavity structure is machined in the soaking plate, and a pedestal temperature-equalizing cavity structure is machined in the pedestal. According to the thermal module, the temperature-equalizing cavity structure is arranged in the pedestal, the heating uniformity of the pedestal is high due to the temperature uniformity property of each point and ultra-low thermal resistance of a temperature-equalizing cavity, and the temperature uniformity of a test tube in each test tube hole is good; furthermore, by arranging the temperature-equalizing cavity structure between the pedestal and each cooling fin, two key problems of rapid heat transfer and uniform heat transfer are solved.

Description

technical field [0001] The invention belongs to the field of biochemical reaction instruments, in particular to a thermal module for biochemical reactions. Background technique [0002] The reaction and storage of biochemical reagents usually need to meet certain temperature conditions. At present, there are many instruments that can control the temperature of the reaction and storage of biochemical reagents, which are widely used in the reactions of various enzymes and the storage of various biochemical samples. Representative instruments for biochemical reactions include high-resolution melting curve instruments, polymerase chain reaction instruments, and the like. [0003] At present, the thermal modules of these instruments are generally composed of multiple devices that are closely attached from top to bottom, including bases, gaskets, heating and cooling components, and heat dissipation components. One side of the heat dissipation components is equipped with a power su...
