How to improve the heat transfer coefficient of finned tubes

Finned tube heat exchangers cannot be used in all occasions. The product has temperature requirements when in use. The coefficient values ​​on both sides of the tube should be similar. If the coefficient values ​​on both sides of the equipment are very different during heat transfer, we can try to control the heat transfer coefficient as small as possible. When designing the equipment, we should pay attention to increasing the heat transfer coefficient value on the inside of the equipment, and basically keep the base numbers on both sides the same.

1. There are many ways to improve the heat transfer coefficient of finned tubes. We can strengthen the heat transfer surface on the equipment.

For example, the porous or grooved surface of the finned tube can obtain a relatively large coefficient during the heat transfer process, which can also reduce the consumption of metal, but the disadvantage is that it increases the production cost and processing difficulty of the enterprise.

2. You can also reduce the flow rate by reducing the cross-section of the finned tube, and add a baffle inside the passage to slow down the turbulence. This use will be used in the tube structure of the equipment.

3. The heat transfer area can also be increased by adding fins on the finned tube equipment, which can increase the turbulence.
