Abstract
The utility model belongs to the technical field of heat exchangers and especially relates to a wave-shaped heat exchanger fin which comprises a wave-shaped fin, wherein a plurality of sunken parts are disposed at intervals at wave peaks of the fin and a plurality of prominences are disposed at intervals at wave troughs. In the utility model, the sunken parts disposed on the wave peaks and the prominences disposed on the wave troughs can increase wall turbulent flow with contact parts of a cooling tube, strengthen heat transmission effect of first heat-dissipation area and increase transmission efficiency of a cooler; and meanwhile, sufficient welding materials can be accumulated at welding parts in order to ensure reliable welding joint strength between the fin and the cooling tube. The wave-shaped heat exchanger fin can be widely applied in different kinds of heat exchangers and can especially act as the heat exchange fin on a gas side in an exhaust gas recirculation cooler.
Description
Technical field:
The utility model belongs to heat exchanger technical field, refers in particular to a kind of corrugated heat exchanger fin.
Background technology:
Along with the increasingly stringent of emission request, EGR Technology is applied on power set more and more, and various structure heat exchangers produce in succession.Wherein, plate-fin structure heat exchanger, because of its remarkable heat dispersion, is more applied.
Conventional plate-fin structure heat exchanger, arranges gas side fin in its gas side.Gas side fin is mainly used in strengthening the coefficient of heat transfer of gas side, improves the radiating efficiency of cooler.Yet in some applications, space is more limited, need the more cooler of high cooling efficiency.
Summary of the invention:
The purpose of this utility model is to provide a kind of heat transfer efficiency that promotes cooler, guarantees the reliable corrugated heat exchanger fin of weld strength between fin and cooling tube.
The utility model is achieved in that
Corrugated heat exchanger fin, includes corrugated fin, is arranged at intervals with several depressions at the crest place of fin, at trough place, is arranged at intervals with several projections.
Above-mentioned depression is circular depressed or oval depressions or yi word pattern depression or cross depression or blossom type depression.
Above-mentioned projection is circular protrusion or elliptical shaped lobes or yi word pattern projection or cross projection or blossom type projection.
Above-mentioned corrugated be trapezoidal corrugated or rectangle is corrugated.
Above-mentioned crest place and trough place are plane or arcwall face.
The utility model compared to existing technology outstanding advantage is:
1, the projection arranging on the depression arranging on crest of the present utility model and trough, can increase the wall flow-disturbing with cooling tube contact site, and the heat-transfer effect of an area of dissipation of strengthening promotes the heat transfer efficiency of cooler; Meanwhile, can make weld gather enough scolders, guarantee that the weld strength between fin and cooling tube is reliable.
2, the utility model can be widely used on various heat exchangers, particularly the heat exchange fin of gas side in cooler for recycled exhaust gas.
Accompanying drawing explanation:
Fig. 1 is the schematic diagram that crest of the present utility model and trough place are plane;
Fig. 2 is the schematic cross-section of Fig. 1;
Fig. 3 is the schematic diagram that crest of the present utility model and trough place are arcwall face;
Fig. 4 is that yi word pattern depression of the present utility model, cross depression, oval depressions, blossom type depression are arranged on the schematic diagram on crest;
Fig. 5 is that the utility model is arranged on the schematic cross-section in cooling tube.
The specific embodiment:
With specific embodiment, the utility model is further described below, referring to Fig. 1-5:
Corrugated heat exchanger fin, includes corrugated fin 1, is arranged at intervals with several depressions at crest 2 places of fin 1, at trough 3 places, is arranged at intervals with some protruding 4.Depression arranges along the length direction interval of crest 2, and the projection 4 length direction intervals along trough 3 arrange.
Above-mentioned depression is circular depressed 5 or oval depressions 6 or yi word pattern depression 7 or cross depression 8 or blossom type depression 9.
Above-mentioned projection 4 is circular protrusion or elliptical shaped lobes or yi word pattern projection or cross projection or blossom type projection.
Above-mentioned corrugated be trapezoidal corrugated or rectangle is corrugated.
Above-mentioned crest 2 places and trough 3 places are plane or arcwall face.
The projection 4 that is arranged on the depression of crest 2 and is arranged on trough 3 can increase the wall flow-disturbing with cooling tube 10 contacts site, and the heat-transfer effect of an area of dissipation of strengthening promotes the heat transfer efficiency of cooler; Can make weld gather enough scolders, guarantee that the weld strength between fin 1 and cooling tube 10 is reliable simultaneously.
In mould, arrange and the projection 4 in fin 1 or the corresponding projection that caves in, the product of therefore producing will be with downward depression and the projection making progress 4.Mould only needs time processing moulding, very convenient.Therefore in producing, do not need to increase the shaping that operation completes depression and projection 4, can not increase extra cost yet.
Above-described embodiment is only one of preferred embodiment of the present utility model; not with this, limit practical range of the present utility model; therefore: all equivalences of doing according to shape of the present utility model, structure, principle change, within all should being covered by protection domain of the present utility model.
