Title:
HEAT EXCHANGER
Document Type and Number:
Japanese Patent JPH0719765
Kind Code:
A
Abstract:

PURPOSE: To remove impurities by condensation from a gas which generates low temperature aerosol by controlling the temperature of a reservoir, enabling thermal contact between a reservoir and a substance, and regulating the temperature of the substance.

CONSTITUTION: A low temperature reservoir 25 is separated from the inner wall of a housing 30 by a arranging an insulator between the low temperature reservoir 25 and the inner wall of the housing 30. The low temperature reservoir 25 includes preferably a solid substance and a heat exchanger 10 controls the temperature of the gas to be within the temperature of 1.1-1.7°C from the desired temperature. The gas to be cooled is input from an inlet 40, cooled passing through a piping 45 and the cooled gas is output from an outlet 50. The piping 45 thermally contacts the low temperature reservoir 25, and as the result of it, the cooling energy of the low temperature reservoir 25 is effectively transferred to the gas through the piping 45. While cooling the temperature of the gas inside the piping 45, all the impurities having the transition temperature exceeding holding temperature are condensed on the inner wall of the piping 45.
