Application & Advantage
High Performance Condensing Tube
It is important to enhance the condenser heat transfer performance by either enlarging the heat transfer surface
Area or increasing the heat transfer coefficient. In a condenser ,heat is transferred from the hot ,high-pressure refrigerant vapor to relatively cool water inside the tube .This reduction in the enthalpy of refrigerant vapor causes
It to condense .It changes from vapor to liquid condensate,and is further subcooled before leaving the condenser.
The traditional low fin tube is quite effective compared with the bare tube in increasing the heat transfer surface area and in enhancing the condensate drainage .
In addition ,our condenser tube is further enhanced 3-5 times by applying staggered  serrated  fin profiles to the exterior surface.It makes the condensate on the outside surface become more turbulent,which enhances the “Gregoring” effect and also improves  the convection heat transfer of the condensing liquid film substantially.On the other hand ,the special 3D configuration improves the surface tension effect of the condensate which facilitates the drainage of condensing liquid flow from the fin tip to the helically arranged fin root channel.Additional inner ridges have further enhanced the overall thermal performance since they have further enhanced the overall thermal performance since they have increased heat transfer surface area and cause more turbulent flow in tube side.
