The core part of the air-temperature vaporizer is the heat exchange device, which obtains powerful heat energy from the atmosphere in the smallest possible space. At present, the heat exchange devices of air-temperature vaporizers produced by domestic manufacturers mostly use anti-embroidered aluminum alloy finned tubes. Because there is no optimal design, most of them have the following disadvantages: huge equipment, high cost, and insufficient product flow. The reason (in addition to artificial factors) mainly lies in the heat transfer area. In order to achieve a certain flow rate, the fins can only be increased. After many studies and experiments, some technical means have been used to solve this problem to the greatest extent. The following is a brief description of this, hoping to play a positive role in the promotion of domestic air-temperature gasifiers.
The structure of the general finned tube is: the finned tube has a central tube, the outside of the tube is radial fins, the liquid flows in the tube, and the fins absorb the heat of the external environment and transfer it to the liquid in the tube to realize the heat absorption and gasification of the liquid. After many experiments and screenings, we selected a new type of finned tube that is different from the above components, and the heat transfer coefficient is increased by more than 50% compared with the former.
