수입압력기인증, KEA inspection for Heat Exchangers in Zurich

A Heat Exchanger is a device used to transfer heat between two or more fluids. It is commonly used in industrial applications, HVAC systems, power plants, and various other processes where efficient heat transfer is essential.

Main Types of Heat Exchangers

1. Shell and Tube Type

   • Structure: Multiple tubes placed within a large shell.

   • Function: Heat exchange occurs between the fluid inside the tubes and the fluid in the shell.

   • Features: Suitable for high pressure and high temperature applications; easy maintenance.

2. Plate Type

   • Structure: Stacked metal plates with fluid flowing between them.

   • Function: Heat transfer between the fluids through thin plates.

   • Features: High thermal efficiency and compact design; ideal for low-pressure and low-temperature applications.

3. Air-Cooled Type

   • Structure: Uses air as the cooling medium.

   • Function: Heat is dissipated to the atmosphere through fins or coils.

   • Features: Commonly used in condensers or cooling towers.

4. Double Tube Type

   • Structure: One tube placed inside another.

   • Function: Two different fluids flow through the inner and outer tubes for heat exchange.

   • Features: Simple design; suitable for small-scale heat transfer.
