Abstract

The utility model relates to a radiating fin which is provided with a corrugating element obtained by folding a thin sheet element. The surface formed by wave crests and wave troughs of the corrugating element is opened with a window. A slope can be formed between the corrugating element and the external surface of a part to be cooled, and the slope, compared with a vertical plane, has better heat absorption performance and cannot block gas circulation; especially, the window opened on the radiating fin can further accelerate the gas circulation, and consequently, the radiating fin with the structure can improve the heat emission efficiency; in addition, the radiating fin is formed by bending the thin sheet element, so that the radiating fin not only has simple structure but also lower manufacturing cost.

Description

A kind of fin

Technical field:

The utility model relates to a kind of fin that is used on the heat-exchange device, particularly relates to a kind of fin that is used on the heavy vehicle engine-cooling system.

Background technology:

Fin is mounted in spreader surface to improve the parts of its radiating efficiency.In when work, water or other cooling liquid that will be used for by water pump in the circulatory system of cooled engine are pumped in the radiator as the motor car engine radiator, turn back to after the radiator cooling in the fluid circulation system of engine to realize cooling again.Radiator is in conversion process of energy, usually adopt fan and these two kinds of parts of fin that the liquid in it is dispelled the heat, fan wherein is to utilize the mode of quickening gas flow to make radiator finish cold and hot exchange, and fin is to utilize the mode that increases area of dissipation to realize cold and hot exchange, under the specified situation of the power output of fan, the speed of its power conversion speed depends primarily on the structure of fin self, particularly for heavy vehicle, because the power output of its engine is very big, usually need be to dispelling the heat simultaneously in the engine and outward, and the space that fan and fin are installed is limited, so, the fin particular importance that can quick heat radiating in the confined space seems.

Yet, fin of the prior art normally adopts the straight plate of interval in a row small distance and is vertically mounted on the structure on the surface of the round radiating tube that rises, what " a kind of water-cooled fin " announced for No. 2730534 as " motor car engine fin " and the Chinese patent of No. 2565995 bulletins of Chinese patent disclosed all is this fin, and its meaning is to want to utilize straight plate to enlarge the surface area of the round radiating tube that rises.Yet, the heat energy on radiating tube surface is to transmit continuously gradually from inside to outside to straight plate because circle rises, straight plate is that the wind that produces by self-radiating and fan this dual mode that dispels the heat is realized heat exchange, and the heat energy on the round radiating tube surface of rising needs a period of time just can add to the outer end of straight plate, so the straight plate that is vertically mounted on the round radiating tube surface of rising not is that the big more radiating effect of surface area is good more; From another point of view, the recess between adjacent two straight plates is the round radiating tube that rises itself, if the surface area of straight plate is excessive, the heat at this position can produce eddy current, is unfavorable for that heat is to external diffusion.

Summary of the invention:

The purpose of this utility model provides a kind of utilization can also make the mode of air proper flow solve the not fin of high problem of radiating efficiency when increasing area of dissipation.

The fin that the utility model proposed has corrugated that is folded into by sheet member, and offers window on formed of this crest of corrugated and trough.

Triangular in shape or the sinusoidal waveform or trapezoidal in described corrugated cross section.

The window class that is provided with on the described fin is similar to shutter.

The fin that the utility model proposed adopts corrugated the structure that offers window, this corrugated and need to form the inclined-plane between the outer surface of cooling-part, and the relative vertical plane in inclined-plane has better heat absorption capacity, and can not hinder gas communication, the window that particularly is provided with on fin can further quicken gas communication, so the fin of this kind structure can improve radiating efficiency; In addition, this fin is to be made of the mode of sheet member by bending, so this fin is not only simple in structure, and cost of manufacture is lower.

Description of drawings:

Accompanying drawing 1 is the surface structure schematic diagram of the embodiment of fin that proposes of the utility model.

The specific embodiment:

Referring to Fig. 1, this figure provides the surface structure of the embodiment of fin that the utility model proposes.This fin is corrugated 1 that is folded into by sheet member, on 12 formed in this crest of corrugated 1 11 and trough, offer window 13, wherein, described corrugated 1 cross section triangular in shape or sinusoidal waveform or trapezoidal or other geometry, and only provide this a kind of structure of shape of shutter in window 13 present embodiments, window 13 can also adopt multiple structure, and window 13 can be offered to a plurality of directions or different directions.

Claims (3)
