What is the specific difference between a condenser and a heat exchanger? Where is it mainly reflected?

First of all, the principle is different

1. heat exchanger: heat is transferred from high-temperature fluid to low-temperature fluid through a heat accumulator made of solid matter. The hot medium is heated to a certain temperature by solid matter, and then the cold medium is heated by solid matter, thus achieving the purpose of heat transfer.

2. Condenser: The gas passes through a long tube (usually coiled into a solenoid) so that the heat can be dissipated into the surrounding air. Metals such as copper have strong thermal conductivity and are often used to transport steam. In order to improve the efficiency of the condenser, heat sinks with excellent thermal conductivity are often attached to the pipeline to increase the heat dissipation area, thus accelerating heat dissipation, and air convection is accelerated by fans to take away heat.

Second, the characteristics are different.

1, heat exchanger: the tube bundle can be drawn out, which is convenient for cleaning the tube and shell side; The temperature difference between media is not limited; Can work under high temperature and high pressure, generally the temperature is less than or equal to 450 degrees and the pressure is less than or equal to 6.4 MPa.

2. Condenser: The working process of the condenser is an exothermic process, so the temperature of the condenser is high.

Third, the application is different.

1, heat exchanger: mainly used in chemical, petroleum, electric power and food industries.

2. Condenser: mainly used in petrochemical industry.
