Difference between high-frequency welded fin tubes and cold-wound fin tubes
The main difference between high-frequency welded fin tubes and cold-wound fin tubes lies in their connection methods and performance characteristics.
Connection method:
High-frequency welded fin tubes are formed by welding fins and steel tubes together through high-frequency welding technology to form an efficient heat transfer element.
This connection method makes the connection between the fins and the steel tubes tighter, thereby improving the heat transfer efficiency and service life.
In contrast, cold-wound fin tubes are formed by wrapping fins around steel tubes, then applying adhesive and curing them to form heat transfer elements.
Although this connection method has a simple manufacturing process, a short production cycle, and low cost, the heat transfer efficiency and service life are relatively low.
Performance characteristics:
High-frequency welded fin tubes have high heat transfer efficiency and long service life due to welding connections.
Its advantages are high heat transfer efficiency, strong durability, and are suitable for various complex working conditions.
Although cold-wrapped finned tubes are simple to make and low in cost, due to their connection method, their heat transfer efficiency and service life are relatively low, and they are suitable for some application scenarios that do not require high heat transfer efficiency and are more sensitive to cost.
High-frequency welded finned tubes are suitable for occasions that require high-performance heat transfer due to their high heat transfer efficiency and long service life.
Cold-wrapped finned tubes are suitable for some application scenarios that are sensitive to cost and do not require high heat transfer efficiency due to their low cost and simple manufacturing process.
