Micro-domain heating apparatus

Abstract

This invention relates to one micro zone heating device for one micro flow chip, which comprises exit, entrance and one work area in between, wherein the above heating device comprises one pre-heatingpart and one heating part; the pre-heating part is set relative to the front micro flow chip and the heating part is connected to the pre-heating part around micro flow chip work area with even temperature distribution.

Description

technical field [0001] The present invention relates to a heating module, and in particular to a microscale heating module. Background technique [0002] There are many applications of microfluidic technology in traditional biochemical analysis, such as micropumps, microvalves, microfilters, micromixers, micropipes, microsensors and other components, most of which are concentrated on biochemical chips for sample pretreatment, mixing , transmission, separation and detection procedures. Among them, the use of microfluidic chips for biomedical detection or analysis has the advantages of reducing experimental errors in manual operations, improving system stability, reducing energy consumption and sample consumption, and saving manpower and time. [0003] Generally speaking, the microfluidic chip uses semiconductor etching technology to carve tiny channels on glass or plastic substrates, allowing the sample to flow in the tiny channels and complete chemical reactions such as sol...

Problems solved by technology

However, due to the heating in a small area, if the length, width and thickness of the resistance heater are not properly designed, there will be a large temperature difference in the heating area.
