【Q&A Question 161】June 10, 2018: Briefly explain what heat exchange is Heat exchange refers to the transfer of heat between two media at different temperatures. Condensation refers to the process in which a substance changes from a gaseous or liquid state to a liquid or solid state. Cooling refers to the process by which an object’s temperature gradually decreases.

Heat exchange refers to the transfer of heat between two media at different temperatures.
Heat exchange refers to the transfer of heat between a cold fluid and a hot fluid, and it is a unit operation that falls under the category of heat transfer processes.
Heat exchange refers to the transfer of heat between two media at different temperatures.
Heat exchange refers to the transfer of heat between a cold fluid and a hot fluid, and it is a unit operation that falls under the category of heat transfer processes. The main purposes of heat exchange are: ① heating, cooling, vaporizing, or condensing materials in order to achieve or maintain the temperature or phase state required by the production process ； ②Comprehensive utilization of heat is achieved by using the hot fluid that needs to be cooled to supply heat to the cold fluid that needs to be heated, thereby improving heat efficiency. Heat exchange operations are widely used in various engineering fields, and are particularly closely related to the chemical industry.
