Explanation:
Fins are extended surfaces that are attached to a heat transfer surface to increase its surface area. The primary purpose of fins is to promote the rate of heat transfer from the surface to the surrounding fluid. The following are the reasons why fins are provided on a heat transfer surface:
Increased Surface Area:
Fins increase the surface area of a heat transfer surface, which enhances the rate of heat transfer. This is because the rate of heat transfer is directly proportional to the surface area of the heat transfer surface. By increasing the surface area, the rate of heat transfer is also increased.
Promotion of Heat Transfer:
The primary purpose of fins is to promote the rate of heat transfer from the surface to the surrounding fluid. Fins increase the surface area of the heat transfer surface, which in turn increases the rate of heat transfer by promoting convection.
Improved Efficiency:
Fins improve the efficiency of a heat transfer surface by increasing the rate of heat transfer without increasing the size of the heat transfer surface. This is especially important in applications where space is limited.
Conclusion:
In conclusion, fins are provided on a heat transfer surface to increase its surface area and promote the rate of heat transfer. By increasing the surface area, fins enhance the efficiency of the heat transfer surface by allowing for more heat to be transferred from the surface to the surrounding fluid.
