What wall thickness is optimal for the heat exchanger to achieve good overall performance?
Thread Content
In the use of central air conditioning systems, the service life of the coil is an important factor. What is the typical wall thickness of the coils you use?
The chillers used generally have a wall thickness of 16 mm; it’s more or less the same, depending on the scale of the equipment
It depends on your design life and whether there is cost control.
First and foremost, quality must be ensured; if the quality of the coolers used cannot be guaranteed, then cost control is nothing but empty talk.

A thickness of 16 is also possible, but no one will buy such products (they’re too expensive, haha). If the thickness is too great, won’t the heat transfer coefficient be much lower? Thicknesses up to 1.2 are ideal (all thicknesses are in mm). PS: What’s mentioned above refers to copper tubes; generally, copper tubes are used for surface coolers, unless brine is used. One more thing: for the heat exchange tubes in surface coolers, there’s a process called tube expansion, and when the tube thickness exceeds 0.5, it seems quite difficult to carry out this process, so the tube thickness is usually kept below 0.5
