Abstract
The utility model relates to radiating fins for water/oil radiators used in engineering machinery and belongs to the radiator technology field. The sine wave-shaped radiating fins are fabricated with an aluminum plate, wherein the sine wave has a rectangular, trapeziform, or triangular cross section. The utility model features a simple structure, easy fabricating, and low producing costs. The sine wave-shaped fins allow an increased secondary heat-exchanging area, improved structural strength, and 15% higher radiating power than other shaped aluminum radiators, 30% higher than copper radiators, remarkably improved vibration-resistance and reliability, a pressure resistant is more than or equal to 68bar for oil radiators and can work in unfavorable conditions. Also, the material costs are lowered by 30%, hence a reduced product weight and lowered material consumption and improved energy saving.
Description
Technical field
The utility model relates to a kind of structure of radiating fin of radiator, belongs to the heat sink technology field.
Background technology
The existing radiator overwhelming majority all will be used radiating fin, in order to improve the heat conduction and the radiating effect of radiating fin, general serrated fin, perforated fin and open louvered fin, its pluses and minuses are as follows: (1) serrated fin: under the identical condition of the pressure loss, its heat transfer coefficient is higher by 30% than plain fin, and heat transfer property cuts length with fin to be changed, it is short more to cut length, its heat transfer property is good more, but increase falls in pressure, generally is used for the occasion of augmentation of heat transfer.(2) perforated fin: its heat transfer coefficient is than plain fin height, but lower than serrated fin, noise and vibration can occur in the high reynolds number scope, is mainly used in Particulate Inclusion or phase-change heat-exchange occasion in flow deflector and the fluid.(3) open louvered fin: owing on fin, have shutter, increased the secondary heat exchange area of fluid, its good heat dispersion performance, but its intensity is low, easily produces and stops up, and generally is used for applying working condition occasion preferably, as automobile radiators.But for engineering machinery, require to adapt to the instructions for use under the bad working environments, require simultaneously to reduce production cost of products, adopt above-mentioned several radiating fin to be difficult to accomplish.
The utility model content
The purpose of this utility model is exactly the deficiency at the radiating fin existence of existing radiator, provides a kind of simple in structure, manufactures easily, production cost is low, coefficient of heat transfer height, perfect heat-dissipating, the radiating fin of the engineering machinery water oil radiator that structural strength is high.
The purpose of this utility model is achieved in that the radiating fin of engineering machinery water oil radiator, it is characterized in that radiating fin is an aluminium matter sinusoidal waveform plate.Rectangular, the trapezoidal or triangle of the section of described waveform.
The utility model is rational in infrastructure simple, manufactures easily, and production cost is low.Utilization is towards wing machine (or high velocity ram machine) and fin mould, the punch process sinusoidal waveform fins, increase the secondary heat exchange area, improve product structure intensity, heat dispersion improves 15% than other structure aluminium radiator, improves 30% than copper radiator, and resistance to vibration, the reliability of product significantly improve, oil radiator is withstand voltage 〉=and 68bar, can satisfy the instructions for use of engineering machinery under bad working environments.Material cost reduces by 30% simultaneously, alleviates the weight of product, saves the energy and material consumption.The sine bellows structure can design different sinusoidal waveform and section structure according to the heat radiation requirement of different radiator products.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1 aluminium sheet, 2 sinusoidal waveforms.
The specific embodiment
With straight aluminium sheet 1 is base material, adopts press to be pressed into sinusoidal waveform 2.
