Miniature fluid temperature controlling device and method thereof

Abstract

The invention relates to micro fluid temperature control device. It include chip, support structure, heat conducting block, and actuator. The chip has reaction chamber used to set micro fluid heated to required reaction temperature by the chip. In cooling operation time, the heat conducing block can contact the chip under the pushing of the actuator to remove heat on the chip by heat conduction type and realize fast cooling. In addition, in heating up operation time, the heat conducing block doesn't contact the chip to make the micro fluid fast heat up to reach the required reaction temperature.

Description

technical field [0001] The invention relates to a temperature control device, and in particular to a microfluid temperature control device and a method thereof. Background technique [0002] Polymerase chain reaction (Polymerase Chain Reaction, referred to as PCR) is to use a small amount of deoxyribonucleic acid (referred to as DNA) polymerase to carry out a specific chain reaction in a chip or a test tube, so that a section of gene is copied into the original 100 100 million to 100 billion times, in order to facilitate the rapid detection of specific pathogenic nucleic acids or disease genes. The gene of DNA is a double helix structure, and when DNA is replicating, the complementary strands of the two double helices bonded by hydrogen bonds must be separated before they can be copied as individual single helices, and the easiest way to open the DNA double helix is ​​to heat. At high temperature, the double-stranded DNA will separate into single strands, and when the tempe...

Problems solved by technology

Since the radiator 110 is fixed on the PCR chip 100, the speed of heating up the PCR chip 100 is slowed down, which affects the time course of the entire temperature control.
