Heat exchange device and heat exchange method

Abstract

A heat exchange device includes: a container in which a gas, and a liquid having a solvent and a solute are sealed in, the solute influencing surface activity of an interface on which the liquid contacts the gas, and the liquid having surface tension that lowers as concentration of the solute increases, in which a high temperature area of the container is at a temperature lower than a boiling point of the solvent and a boiling point of the solute, and a low temperature area of the container is at a temperature lower than a solidification point of the solvent.

1 . A heat exchange device comprising:
 a container in which a gas, and a liquid having a solvent and a solute are sealed in, the solute influencing surface activity of an interface on which the liquid contacts the gas, and the liquid having surface tension that lowers as concentration of the solute increases, wherein   a high temperature area of the container is at a temperature lower than a boiling point of the solvent and a boiling point of the solute, and   a low temperature area of the container is at a temperature lower than a solidification point of the solvent.   
     
     
         2 . A heat exchange device comprising:
 a container in which a gas, and a liquid having a solvent and a solute are sealed in, the solute influencing surface activity of an interface on which the liquid contacts the gas, and the liquid having surface tension that lowers as concentration of the solute decreases, wherein   a high temperature area of the container is at a temperature lower than a boiling point of the solvent and a boiling point of the solute, and   a low temperature area of the container is at a temperature lower than a solidification point of the solute.
