英语翻译
A heat exchanger is a device built for efficient heat transfer from one medium to another,whether the media are separated by a solid wall so that they never mix,or the media are in direct contact.[1] They are widely used in space heating,refrigeration,air conditioning,power plants,chemical plants,petrochemical plants,petroleum refineries,and natural gas processing.One common example of a heat exchanger is the radiator in a car,in which a hot engine-cooling fluid,like antifreeze,transfers heat to air flowing through the radiator
