G Type Embedded Spiral Finned Tube
A finned tube is a heat exchange element. In order to improve the heat exchange efficiency, fins are usually added to the surface of the heat exchange tube to increase the outer surface area (or inner surface area) of the such a heat exchange tube.
The outer surface of the finned tube is covered with small fins. The function of these fins is to act as a transfer process and filtration. Heat is usually transferred from the inside to the outside and then in reverse.
Aluminum fin strips are wound and embedded in grooves and are securely locked in place by closing the grooves with the bottom metal tube. This ensures maximum heat transfer at high temperatures.
The maximum operating temperature of the G-type heat sink is 450 degrees Celsius. Commonly used materials for heat sinks are aluminum (or) copper, carbon steel tubes, stainless steel, copper, copper alloys, etc.
