Abstract
The invention discloses a heat exchanger fin and a manufacturing method thereof. The fin is of a complete piece; the fin is in the mode of a continuous corrugated plate; continuous corrugated slots are formed in the fin; each corrugated slot comprises a plurality of unit waves which extend transversely; and the wavelength d of the unit wave ranges from 8mm to 15mm. In such mode, the fin is convenient to wash when being used, is simple in manufacturing method and higher in production efficiency.
Description
technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a fin structure of a heat exchanger and a manufacturing method thereof. Background technique [0002] The plate-fin heat exchanger is considered to be one of the most promising new heat exchange equipment because of its compact structure, light weight and high heattransfer efficiency. It has been widely used in sub-equipment, deep low temperature and other industrial sectors, especially in the construction machinery industry. The working environment of construction machinery equipment is usually very harsh. During the operation process, it is often accompanied by the flying of sand and dust. These sand and dust are easy to accumulate on the surface of construction machinery, especially on the outer fins of the radiator. However, the outer fins of radiators used in construction machinery are mostly louver-shaped or staggered-toothed, and dust is difficult to clean after ...
