The automotive market for heat exchangers requires a different set of requirements. Cost, mass and packing constraints are key drivers for this product. Aluminium wire fin on tube is ideally suited to meet all the 3 key constraints. Fins can be added to long lengths of tube without joints so that the heat exchanger becomes part of the fluid line.
The wire fin technology operates well in confused air flow application as the thermal performance is not hindered in this environment. These heat exchangers can be used for high pressure applications as the application of the fin does not affect the mechanical integrity of the tubing.
Aluminium is the most common fin and tubing material, but stainless steel and plated carbon steel tubing can also be used where the application requires extra strength or durability. A range of tube diameters and fin configurations are available to meet customer requirements.
