Description
Technical Field
The utility model relates to a last part of refrigerating plant, especially use the fin on air-cooled condenser.
Background
The fins originally applied to the condenser are made of various materials and have different specifications, and meet the refrigeration requirements of enterprises to a certain extent, but the fins have problems in different degrees, and some fins are rusted for a long time; some have low heat exchange efficiency and waste energy.
Disclosure of Invention
The utility model aims at providing a fin which has higher heat exchange efficiency and is applied to an air-cooled condenser, solving the difficult problems of other prior arts, and the utility model aims to realize that a corrugated structure with the width of 5-15mm is arranged on a thin aluminum fin, a perforation is arranged on the fin with the corrugated structure, the top end in the middle of each corrugation is a disturbing wind convex plane, the width of the disturbing wind convex plane is 1-3mm, and the included angle between the disturbing wind convex plane and two side walls is 5-15 degrees; the diameter of the through hole is 5-15mm, the edge of the through hole is provided with an inner step, and the height of the inner step is 0.5-1.5 mm.
The back of the fin is provided with a plurality of rows of disturbing air grooves corresponding to the disturbing air convex plane on the front, the width of the bottom plane of each disturbing air groove is 1-3mm, each row of the plurality of rows of disturbing air grooves is provided with a row of through holes at intervals, and the through holes on the front are the same; the edge of the through hole is provided with a connecting hole wall, and the height of the connecting hole wall is 1-4 mm.
The perforations on the two adjacent rows of fins are arranged in a staggered manner; the distance between the centers of two adjacent rows of perforations is 20-30mm, and the distance between the centers of every two adjacent rows of perforations is 20-30 mm.
The utility model discloses an application method is, including the multiunit board subassembly of wearing in the condenser core, there is the fin on the multiunit board subassembly of wearing, wear many heat exchange coil on the board subassembly, its fin of indefinite quantity wears on heat exchange coil, connect by connecting the elbow between its heat exchange coil fixedly, and communicate; one end of the air exchange coil pipe is provided with an air inlet pipe assembly, and the other end of the air exchange coil pipe is provided with a liquid outlet pipe assembly; when the refrigerant passes through the heat exchange coil and the fins, the corrugated structure of the fins can play a role in disturbing the wind layers, so that the temperature difference of each wind layer is better reduced, and the heat value contained in unit air volume is greatly increased; under the same heat exchange area, the heat exchange efficiency of the corrugated fins is obviously improved compared with that of the common flat plate.
The significance of the utility model is that the fin has long service life; the energy is saved; the staggered arrangement mode is adopted, so that the structure is reasonable; the heat exchange coil pipe and the aluminum fins are tightly combined by using the mechanical tube expansion, and the heat exchange efficiency is high.
