Description
Technical field
The invention belongs to fin-tube heat exchanger technical fields, and in particular to a kind of fin and the heat exchange containing the fin
Device.
Background technique
Fin-tube heat exchanger is the most widely used a kind of heat exchange equipment in gas and liquid exchange, is in refrigerator
The most common heat exchanger.As shown in Figure 1, fin-tube heat exchanger is to reach strong by installing fin 2 additional on common base tube 1
Change the purpose of heat transfer.
In order to which heat exchange area is significantly increased, mostly use greatly in the prior art in flat plate fin heat-exchanging fin, mainly
Having the disadvantage in that plate-fin fin is smooth, fluid flow direction is parallel with fin, when fluid flows through plate-fin fin, flowing
Characteristic is laminar state, rubs between fluid and fin small, and disturbance is small, prevents fin with fluid from sufficiently exchanging heat.
Summary of the invention
It is an object of the invention to overcome above-mentioned the deficiencies in the prior art, providing one kind can be with fluid (such as moving air)
The fin sufficiently to exchange heat.
The present invention also provides a kind of heat exchangers containing the fin.
The first aspect of the present invention provides a kind of fin, including fin body, uniformly offers multiple use in fin body
In the through-hole of suit base tube, it is transversely provided with convex embossing group between upper adjacent through-hole in the horizontal direction, convex embossing group includes
Convex embossing and under convex embossing, convex embossing and under convex embossing from the surface elevation of fin body, lateral side
It is respectively formed opening.
The second aspect of the present invention provides a kind of heat exchanger containing the fin comprising base tube and above-mentioned fin sheet
Body.
The present invention is improved by the structure to fin, is increased the friction between fluid and fin, is increased disturbance, makes to change
Thermal effect is significantly reinforced.
Other features and advantages of the present invention will the following detailed description will be given in the detailed implementation section.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of fin-tube heat exchanger in background technique；
Fig. 2 is the structural schematic diagram of fin in the present invention；
Fig. 3 is the structural schematic diagram of heat exchanger in the present invention.
Specific embodiment
Referring to fig. 2, a kind of fin provided by the invention, including fin body 3 uniformly offer in fin body 3 multiple
For being set with the through-hole 4 of base tube, convex embossing group 5, convex embossing group are transversely provided between upper adjacent through-hole 4 in the horizontal direction
5 include convex embossing 51 and under convex embossing 52, convex embossing 51 and under convex embossing 52 from fin body 3 surface it is grand
It rises, lateral side is respectively formed opening 53.(above-mentioned surface elevation is included in the same face protuberance or respectively in two-sided protuberance, above-mentioned cross
To side include convex embossing 51 and under the opposite or opposite side of convex embossing 52.The corresponding attached drawing of the present embodiment is convex
Embossing 51 and under convex embossing 52 swelled in the same face of fin body 3, opposite side forms opening 53.)
Its working principle is that: fin body 3 not only increases the heat exchange of fin body 3 due to being provided with multiple convex embossing groups
Area is better than plain fin (plate fin heat-exchanging fin i.e. described in background technology) in terms of heat exchange, in addition also makes flowing empty
Gas constantly changes direction wherein, has more air to wash away the section of each convex embossing, which adds flow-disturbing, makes to change
Thermal effect is significantly reinforced.
In the present embodiment, convex embossing 51 is at least three, from convex embossing 52 under separate to the convex embossing under
On 52 direction, the length of convex embossing 51 is sequentially reduced；Under convex embossing 52 it is identical as the item number of convex embossing 51, from
Far from convex embossing 51 on the direction of convex embossing 51, under the length of convex embossing 52 be sequentially reduced, and length
It is respectively corresponded with convex embossing 51 identical.Purpose is, at least three convex embossing 51 and under convex embossing 52, make convex
The area of fin body 3 shared by embossing group is sufficiently large, it is ensured that heat exchange and the reliable realization of flow-disturbing effect.
In the present embodiment, the both sides of fin body 3 along its length are equipped with waveform embossing 6.Purpose is that it is possible to
The further heat exchange area for increasing fin body 3, and keep moving air real at the wave crest and trough of waveform embossing 6
The change suddenly of existing speed, further increases flow-disturbing effect, makes heat transfer effect more preferably.
In the present embodiment, through-hole 4 turns up along hole edge equipped with wide bound edge 7, and wide bound edge 7 is close to be wrapped in the outer wall of base tube 1
On.Purpose is, increases contact area between fin body 3 and base tube 1, improves heat transfer effect, in addition connection structure is secured
Property also increases, and keeps properties of product more reliable and more stable.
In the present embodiment, fin body 3 is in addition to can be selected metal material system used by heat exchanger fin in the prior art
At being preferably made of thermal conductivity, the good synthetic material of ductility (asepsis environment-protecting, highly corrosion resistant).
Referring to Fig. 3, the present invention also provides a kind of heat exchangers containing the fin comprising base tube 1 and above-mentioned fin sheet
Body 3.The attached drawing of the present embodiment is the arrangement of 3 parallel interval of multiple groups fin body, and base tube 1 is inserted perpendicularly into arrangement therein,
It is contemplated that by segmentation fin body 3, the fin body 3 that a base tube 1 is inserted into after multiple segmentations is formed by heat exchange
The modes such as device, or the length shapes by changing base tube 1, can all be adjusted according to actual needs, therefore this implementation
It will not go into details for example.
The above is only a preferred embodiment of the present invention, protection scope of the present invention is not limited merely to above-mentioned implementation
Example, all technical solutions belonged under thinking of the present invention all belong to the scope of protection of the present invention.It should be pointed out that for the art
Those of ordinary skill for, several improvements and modifications without departing from the principles of the present invention, these improvements and modifications
It should be regarded as protection scope of the present invention.
