Novel efficient cooling fin of radiator

Technical Field

The utility model belongs to the technical field of the radiator technique and specifically relates to a novel high-efficient cooling fin of radiator.

Background

The radiator is widely applied to various industries. Cooling fins are an important component of heat sinks. The traditional cooling fins are flat fins, the tube pitch distribution is unreasonable, and the air resistance is large; a laminar bottom layer is generated when air flows, and the thermal resistance is large; meanwhile, the contact area between the fins and the cooling pipe is small, and the heat transfer efficiency is not high; the strength of the fins is low; a novel efficient cooling fin of a radiator is urgently needed, and the defects of a traditional flat fin are overcome.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a novel high-efficient cooling fin of radiator to the defect to current flat fin to overcome prior art not enough.

In order to solve the problems, the utility model is optimized on the basis of the traditional flat fin, and the resistance to air is reduced by reasonably distributing the hole pitch of the cooling pipe; and the symmetrical trapezoidal shutter is adopted to destroy the laminar bottom layer of cooling air on the surface of the cooling fin, so that the thermal resistance is reduced.

The utility model adopts the technical proposal that: it includes fin (1), has evenly arranged cooling tube hole (2) on fin (1), its characterized in that: the symmetrical trapezoid louver bodies (3) are uniformly distributed on the two sides of the upper fin (1) and the lower cooling tube hole (2), the edge of the fin (1) is of a corrugated line structure (4), the windowing angle of the trapezoid louver bodies is 27 degrees, the row distance of the cooling tube hole (2) is 27mm, the tube distance is 33mm, and the cooling tube hole (2) protrudes out of the surface of the fin (1).

The wave pitch of the corrugated line structure (4) at the edge of the fin (1) is 6.6mm; the cooling pipe hole (2) protrudes 1.4-2.5mm from the surface of the fin (1).

The utility model has the advantages that: the resistance to air is reduced by reasonably distributing the hole pitch of the cooling pipes; the symmetrical trapezoidal shutter is adopted to destroy the laminar bottom layer of the cooling air on the surface of the cooling fin, so that the thermal resistance is reduced; the edges of the fins are corrugated lines, so that air disturbance is increased, and the heat dissipation efficiency is improved; the cooling pipe hole adopts a stamping and stretching process, protrudes out of the surface of the fin, increases the contact area of the fin and the cooling pipe, and improves the heat transfer efficiency; through the structural innovation, the heat transfer efficiency of the fin is remarkably improved. Simultaneously, the bonding rate with the cooling pipe and the strength of the fins are greatly improved. The method is widely applied to hydrogen production cooling equipment, power generation equipment and the like.
