The inner grooves have a helical shape and have been optimized for heat transfer. The heat transfer coefficient of the tube is improved by two times over that of ordinary smooth bore tubes. This greater efficiency can aid in the construction of more compact heat exchangers and the decrease of refrigerant load.
Different groove depths and geometries fulfill regional requirements and refrigerant types in use.
* Straight grooves
* High heat transfer efficiency
* Easy to shape and bend * Low cost and weight
* Helical grooves
* Very high heat transfer efficiency
* Easy to form and bend * Low cost and weight
