Abstract
The utility model provides a kind of narrow tooth root air-conditioning refrigerating heat exchange riffled tube, it comprises: on pipe material inner wall, be uniformly distributed a kind of new tooth, this tooth is a kind of combination tooth, each tooth is made up of high tooth 1 and low tooth 2, their combination is 212,21 bilateral symmetry distribution, two low teeth are less than the width L1 of two low teeth near tooth top near the width L2 of inwall side.Two adjacent groups is closed between tooth and is formed a groove.This profile of tooth had both added gasification core amounts, increased heat exchange area, and the formation of groove simultaneously adds refrigerant turbulence level, has the advantage of high efficient heat exchanging.
Description
Technical field
The utility model relates to a kind of tubing, says accurately and relates to a kind of narrow tooth root air-conditioning refrigerating heat exchange riffled tube.
Background technology
Refrigeration air-conditioner heat exchanger internal thread tubing has multiple profile of tooth at present, there are full depth tooth, intersection tooth, tall and thin tooth, stage teeth, M type tooth, Y type tooth, chevron tooth etc., often kind of tooth compares light face copper pipe, heat exchange performance has raising in various degree, but in production and use, there is its limitation, as great in full depth tooth, M type tooth (application number 02232597.2) Mick, heat exchange efficiency is relatively low; Y type tooth (200510107334.X), tooth (application number 02237272.5 and application number 03284022.5) heat exchange efficiency of intersecting are high, are difficult to machine-shaping; Chevron tooth (application number 200820004885.2), Mick is great, and tooth bar number is relatively few, and heat exchange effect is not good enough.
Utility model content
The purpose of this utility model is: provide a kind of composite tooth form, can improve the heat exchange performance of riffled tube further.
The technical solution of the utility model is: a kind of narrow tooth root air-conditioning refrigerating heat exchange riffled tube, comprise riffled tube inwall side circumference and be uniformly distributed many protruding combination teeth, described combination tooth comprises a high tooth and two low teeth, two low teeth distribute in the bilateral symmetry of high tooth, and two low teeth and high tooth have arc transition, two low teeth are less than the width L1 of two low teeth near tooth top near the width L2 of inwall side.
The addendum angle α of described high tooth and the addendum angle β of low tooth is all less than 30 °, and outside the groove that described two adjacent groups conjunction tooth is formed, included angle of straight line γ is less than 40 °, the discrepancy in elevation h formed between described high tooth and low tooth
fshould be greater than 0.05mm, the helical angle of described combination tooth is less than 45 °.
The combination tooth of the utility model narrow tooth root air-conditioning refrigerating heat exchange riffled tube had both added gasification core amounts, increase heat exchange area, the formation of groove simultaneously adds refrigerant turbulence level, there is the advantage of high efficient heat exchanging, overall heat exchange performance is good, in two device processing expand tube operations, low tooth is indeformable, extends service life.
Accompanying drawing explanation
Fig. 1 is the profile of tooth cross section partial enlarged drawing of the utility model narrow tooth root air-conditioning refrigerating heat exchange riffled tube;
1. high teeth, 2. low tooth in figure.
Detailed description of the invention
The specific embodiment of the utility model narrow tooth root air-conditioning refrigerating heat exchange riffled tube as shown in Figure 1, it comprises riffled tube inwall side circumference and is uniformly distributed many protruding combination teeth, described each combination tooth comprises a high tooth 1 and two low teeth 2, described two low teeth 2 distribute in the bilateral symmetry of high tooth 1, and two low teeth 2 have arc transition with high tooth 1, described high tooth 1 will have certain difference in height h with low tooth 2
f, described two low teeth are less than the width L1 of two low teeth near tooth top near the width L2 of inwall side, and addendum angle α, the β of described high tooth 1 and low tooth 2 are all less than 30 °, and addendum angle is large, and Mick is heavy will be increased; Outside the groove that described two adjacent groups conjunction tooth is formed, included angle of straight line γ is less than 40 °, and γ is too large, and mould is difficult to processing, is difficult to shaping when production simultaneously; The discrepancy in elevation h formed between described high tooth 1 and low tooth 2 tooth
fshould 0.05mm be greater than, ensure that low tooth 2 is indeformable in two device processing expand tube operations; The helical angle of described combination tooth is less than 45 °.
Claims (5)
1. one kind narrow tooth root air-conditioning refrigerating heat exchange riffled tube, comprise body, it is characterized in that, described riffled tube inwall side circumference is uniformly distributed many protruding combination teeth, described combination tooth comprises a high tooth and two low teeth, two low teeth distribute in the bilateral symmetry of high tooth, and two low teeth and high tooth have arc transition, and two low teeth are less than the width L1 of two low teeth near tooth top near the width L2 of inwall side.
2. narrow tooth root air-conditioning refrigerating heat exchange riffled tube according to claim 1, it is characterized in that, the addendum angle α of described high tooth and the addendum angle β of low tooth is all less than 30 °.
3. narrow tooth root air-conditioning refrigerating heat exchange riffled tube according to claim 1, is characterized in that, outside the groove that described two adjacent groups conjunction tooth is formed, included angle of straight line γ is less than 40 °.
4. narrow tooth root air-conditioning refrigerating heat exchange riffled tube according to claim 1, is characterized in that, the discrepancy in elevation h formed between described high tooth and low tooth
f0.05mm should be greater than.
5. narrow tooth root air-conditioning refrigerating heat exchange riffled tube according to claim 1, it is characterized in that, the helical angle of described combination tooth is less than 45 °.
