Description
Technical field
The utility model relates to the heat exchange field, in particular to a kind of fin-tube heat exchanger.
Background technology
One of problem of current air-conditioner industry primary study is to improve the heat exchange efficiency of heat exchanger of air condition and reduce the heat exchanger cost.The used accurate inner screw thread copper pipe of fin-tube heat exchanger U type pipe.Pathization, thin-walled property become one of emphasis direction.Copper pipe external diameter of pipe exploitation is from 9.52mm, then towards 8.0mm, 7.0mm, the direction of 6.35mm develops, now external diameter be 5-6mm or more the copper pipe of minor diameter bring into use.
The inventor finds that there are the following problems at least in the prior art:
Though small caliber inner screw thread pipe intraductal heat exchange coefficient increases, unit length intraductal heat exchange area is littler than other riffled tubes such as 7mm, and heat exchange tube outer fin in existing tubule footpath is listed as apart from ubiquity phenomenon less than normal, can't directly substitute big caliber heat exchanger tube.For example, the pitch-row of existing Ф 5mm caliber fin mostly is 19.05, and line-spacing is 11-12mm, and the sheet type is bridge sheet or window, is used for indoor evaporator more.Though the coefficient of heat transfer of this fin fin side is higher, because its fin side heat exchange area is less, so whole heat exchange property is not high.
The utility model content
The utility model aims to provide a kind of fin-tube heat exchanger, and is less to solve existing fin side heat exchange area, the problem that whole heat exchange property is not high.
In embodiment of the present utility model, a kind of fin-tube heat exchanger is provided, comprising: caliber is smaller or equal to many groups U type pipe of 6mm; Many group fins, expanded joint is outside many groups U type pipe abreast; Many group fins are provided with a plurality of installing holes that at least two row are pegged graft for a plurality of U type pipes, and the spacing P of adjacent two installing holes equates and P=18～21mm, the line-spacing S=15.6～18.2mm of two row installing holes.
Preferably, the caliber of organizing U type pipe is 5mm to 6mm more.
Preferably, the spacing P=19.05mm of adjacent two installing holes.
Preferably, the line-spacing S=16.5mm of two row installing holes.
Preferably, fin is plate fin or corrugated fin or bridge sheet.
Preferably, corrugated fin is W type or sinusoidal waveform.
Preferably, fin thickness is 0.08～0.2mm.
Be provided with a plurality of installing holes that at least two row are pegged graft for a plurality of U type pipes because organize fin more, the spacing P of adjacent two installing holes equates and P=18～21mm, line-spacing S=15.6～the 18.2mm of two row installing holes, so increased fin side heat exchange area, improve whole heat exchange property, and then reached and have higher heat exchange efficiency, air flow resistance is little, heat exchanger is applied widely, characteristics such as the equipment input cost is low are simplified production technology simultaneously to a certain extent, enhance productivity.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, constitutes the application's a part, and illustrative examples of the present utility model and explanation thereof are used to explain the utility model, do not constitute improper qualification of the present utility model.In the accompanying drawings:
The fin that Fig. 1 has schematically shown according to the utility model embodiment is the structure of φ 5 tube wave corrugated fins;
The fin that Fig. 2 has schematically shown according to the utility model embodiment is the structure of φ 5 pipe bridge sheets.
The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
The fin that Fig. 1 and Fig. 2 have schematically shown according to the utility model embodiment is the structure of φ 5 tube wave corrugated fins and bridge sheet.About the structure of U type pipe, prior art is existing to be related to, and does not repeat them here, and illustrates no longer separately among the figure, mainly shows the structure of fin below.As shown in the figure, the fin-tube heat exchanger according to the utility model embodiment comprises: caliber is smaller or equal to many groups U type pipe of 6mm; Many group fins 10, expanded joint is outside many groups U type pipe abreast; Many group fins are provided with a plurality of installing holes that two row are pegged graft for a plurality of U type pipes, the i.e. first row installing hole S1 and the second row installing hole S2, many group fins pass through these installing hole 11 expanded joints outside many groups U type pipe, the spacing P of adjacent two installing holes 11 equates and P=18～21mm, the line-spacing S=15.6～18.2mm of two row installing holes.
Because the line-spacing S=15.6～18.2mm of the installing hole of fin, the line-spacing S=11-12mm of more existing installing hole has increase by a relatively large margin, therefore, increased fin around area, in addition, original small pipe diameter fin adjacent holes center distance does not wait, and promptly the straight cutting eyesight elbow is different with oblique cutting eyesight elbow size, needs to be equipped with two different eyesight elbow bending machines, when influencing production efficiency, cause the increase of equipment input cost, and the spacing P of adjacent two installing holes 11 of the fin-tube heat exchanger of the utility model embodiment equates, so, only need an identical eyesight elbow bending machine, when having improved production efficiency, reduce the equipment input, reduced cost.
Preferably, the caliber of organizing U type pipe is 5mm to 6mm or minor diameter more more, can improve the coefficient of heat transfer.
Preferably, the spacing P=19.05mm of adjacent two installing holes.Like this, pitch-row is comparatively reasonable.
Preferably, the line-spacing S=16.5mm of two row installing holes.Like this, heat exchange area is comparatively reasonable.
Preferably, fin is plate fin or corrugated fin or bridge sheet.As shown in Figure 1, fin is a corrugated fin, and corrugated fin is with flat fin press forming, and its characteristics are strengthened the mobile turbulence intensity of air when increasing the outer fin heat exchange area of pipe; As shown in Figure 2, fin is the bridge sheet, and it has high heat exchanger effectiveness, the little characteristics of air flow resistance.
Preferably, corrugated fin is W type or sinusoidal waveform, like this, strengthens the turbulence intensity that air flows when can further increase the fin heat exchange area.
Preferably, fin thickness is 0.08～0.2mm, and like this, the heat exchange effect is better.
As can be seen from the above description, the utility model the above embodiments have realized following technique effect:
Characteristics such as the fin-tube heat exchanger according to the utility model embodiment has higher heat exchange efficiency, and air flow resistance is little, heat exchanger is applied widely, and the equipment input cost is low are simplified production technology simultaneously to a certain extent, enhance productivity.
The above is a preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
