Heat Exchangers

A heat exchanger transfers heat between fluids at different temperatures and is used in air conditioning, power generation, chemical processing and food processing. These articles explain how heat exchangers work, the main types such as shell-and-tube and plate, and how to choose one.

Stainless steel and copper tubes for heat pipes and shell-and-tube heat exchangers often need a closed end; TONG DA's TD-31040 tube closing machine spin-forms a one-piece closed end at room temperature, with no weld and no plug. For quotations or sample closing, email sales@tdco.com.tw.

How Are Heat Pipe and Heat Exchanger Tubes Closed? Copper and Stainless Tube Closing

Tubes in heat pipes and heat exchangers must hold the working fluid's pressure through repeated heating and cooling, so the closure cannot have weld porosity or a plug gap.TD-31040 closing machin...

Structure and Features of Plate Heat Exchangers

Structure of a plate heat exchangerA plate heat exchanger is built from a stack of pressed stainless steel plates with a corrugated pattern. Adjacent plates are turned 180° to each other, so the ...

Types and Principles of Heat Exchangers

What is a heat exchanger?A heat exchanger transfers heat between two or more fluids. The fluids may be separated by a solid wall so they do not mix, or they may be in direct contact. Heat exchangers ...
