Selection of finned tube heat exchanger spacing and chip spacing

The finned tube heat sink is mainly composed of three rows of parallel spiral finned tube bundles, and air flows between them. It not only saves the use area, but also has better heat dissipation effect and saves energy. Beautiful appearance, has been favored by customers since it was put on the market。 Yes, very good heating products.

The finned tube heat sink spacing and fin height primarily affect the fin ratio。 The fin ratio has a great relationship with the heat transfer coefficient inside and outside the tube。 If the internal and external heat transfer coefficients differ greatly, you should choose a finned tube with a larger fin ratio, such as steam to heat the air. When a phase change occurs on one side of the medium, the heat transfer coefficient differs greatly, such as the exchange of hot and cold air。 When the hot air is lower than the dew point, a finned tube heat sink can be used。 In the case where phase change heat transfer or heat exchange between water and water does not occur between air and air, a bare tube is usually employed。 Of course, it is also possible to use a low finned tube, since this is a weak heat transfer coefficient, and any side of the reinforcing tube has a certain effect. However, the effect of excessive fin rate is not obvious, and the contact area inside and outside the tube is strengthened, and a threaded tube or a grooved tube can be used.

The finned tube heatsink is the most widely used heat exchanger in gas-liquid heat exchangers. It has many types such as curved louver fins and rectangular louver fins. A large number of experiments have found that friction is inevitably increased while obtaining good heat transfer characteristics. Given a heat exchanger size and fan operating curve, an increase in pressure loss necessarily results in a decrease in wind speed and a temperature difference between the air and the fin wall. Secondly, the heat exchangers used in air-conditioning projects are mostly dry and wet。 The heat transfer characteristics and resistance characteristics of different finned heat exchangers under wet conditions are very different from those under dry conditions。 Therefore, how to correctly select the fin form has a non-negligible influence on the actual working characteristics of the heat exchanger. This is looking for a compromise between heat transfer and resistance loss。
