Abstract:
PURPOSE: A method and an apparatus for controlling temperature of a PCR chip are provided to reduce a time for analysis and experiment by analyzing simultaneously DNA samples under different temperature conditions. CONSTITUTION: An apparatus for controlling temperature of a PCR chip includes a PCR chip(1051), a power supply portion(1041), and a control portion(102). The PCR chip(1051) is used for generating the heat by using the external electric power, maintaining the predetermined temperature, and outputting the practical temperature information to the outside. The power supply portion(1041) supplies the electric power to the PCR chip(1051) according to a control signal. The control portion(102) generates the control signal by using the control information including the control temperature information and the control time information and the practical temperature information of the PCR chip(1051).
Abstract:
PURPOSE: A closed fluid circuit system for flowing a biochemical fluid along closed chamber sections differentiated in the temperature is provided which, therefore, involves neither heating and cooling processes nor a temperature control circuit, thereby performing a polymerase chain reaction (PCR) within a significantly shortened period of time. CONSTITUTION: The closed fluid circuit system has a unit structure including a chamber for storing the target fluid therein at a predetermined temperature, passive and active valves placed at the inlet and the outlet portions of the chamber, and pneumatic air pressure ports positioned at the inlet and the outlet portions of the chamber to control the inflow and outflow of the fluid. Two or more of such unit structures are linked together. The target fluid circularly flows through the chambers under predetermined temperature conditions(T1,T2,T3).

Abstract:
PURPOSE: A cooling apparatus having a micro cooling fin is provided to improve heat transfer capacity by preventing a heat boundary layer formed on a smooth surface of the board to reduce heat transfer resistance. CONSTITUTION: A plurality of vibrating cooling fins(12) are extended from a board(10). An air blower blows air to the board to cool the board and the cooling fin, and supplies vibrating power to the vibrating cooling fin. The vibrating cooling fin is extended in a plane direction of the board, and has a cavity part under the vibrating cooling fin.
