The main function of the fin tube is to dissipate heat and cool, but the more fins on the fin tube on the machine that are not used for cooling, the better? The answer is, of course, denial. If you want to ask why, I will tell you the reasons below.
1. When the heat transfer area of the fin tube fin doubles, the heat transfer coefficient cannot be doubled, but a discount is required. The individual is (0.9-0.7 This means that the more fins, the more fins The lower the efficiency, the lower the economic efficiency of adding fins.
2. The fins are too high and dense, which will increase the difficulty of the process and increase the processing cost.
3. If the fins are too high or dense, it is easy to cause dust accumulation and it is difficult to clean dust.
Therefore, how many finned tubes are selected depends on the calculation of the finning ratio, that is, the ratio of the total heat transfer area after adding the fins divided by the total area of the unadded fins. According to normal regulations, it is generally believed that the finning ratio is around 5 to 10, so everyone must choose a reasonable choice when choosing a finned tube. It is also very reasonable that the material must be reversed.
Analysis on how to choose finned tube to be safe
Finned tubes have a wide range of uses and many applications. Among them, they are mainly used in industrial production. Because the factory is densely staffed, in order to protect the personal insurance of the mission staff, I should pay attention to the following points when purchasing finned tubes. problem:
1. Insurable
This is the most important identity. If this cannot be satisfied, no one will use it. Prohibited items that cannot be guaranteed for personal insurance cannot appear on the market. Therefore, individuals can only purchase from a proper machinery factory. will happen.
2. Durability
Secondly, when purchasing a finned tube, pay attention to its operating life. The longer the used life, the lower the cost, the slower the replacement, and the savings. The factory must wish the less money the painting is, the better. Therefore, durability has always been an important factor in the purchase of finned tubes.
3. Environmental protection
Environmental protection is similar to insurance, but environmental protection is more about the insurance performance of the environmental atmosphere, so when deciding on the finned tube, I have to choose a green and on-track security inspection department will often check the factory processing. Imprison the waste water of the gas battle platoon, so don't choose the cheap one because of the cheap price. Once the problem is found, you will face the major problem of fines and closure of the factory.
Therefore, when choosing a finned tube, most of the main considerations are to save money and safety. These are the most basic purchase factors. People in different industries can add more considerations according to their own needs. That is the best.
