Description

Technical Field

Heat exchangers play an important role in chemical, petroleum, power, food and many other industrial productions. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc., and are widely used. After searching, the prior art (Announcement No.: CN209470386U) records "an energy-saving train heat exchanger, wherein one end of the upper guard plate is connected to the top of the left end plate, the other end of the upper guard plate is connected to the top of the right end plate, the bottom end of the left end plate is connected to one end of the lower guard plate, and the bottom end of the right end plate is connected to the other end of the lower guard plate. A plurality of intermediate plates are arranged between the left end plate and the right end plate, fins are arranged on both sides of the intermediate plates, and a plurality of elliptical copper tubes are arranged between the upper guard plate and the lower guard plate. The liquid distributor is connected to one end of the elliptical copper tube, and the air collecting pipe is arranged on the outer side of the left end plate. The utility model has a reasonable structure, and the copper tube and the fin hole both adopt an elliptical structure. Compared with the circular tube, the elliptical tube can effectively reduce the negative wind resistance caused by the Karman vortex street; at the same time, it reduces the flow speed of the refrigerant in the tube, effectively improves the refrigeration efficiency of the product, and is smaller in size than the circular tube product with the same refrigeration capacity, thereby solving the shortcomings of the large size and heavy weight of the train air conditioner and ensuring the refrigeration capacity at the same time."
