Accompanying drawing explanation
Describe the feature of exemplary embodiment of the present invention, advantage and technology and industrial significance hereinafter with reference to the accompanying drawings, Reference numeral identical in the drawing represents identical element, and wherein:
Fig. 1 is the sectional view of the irregular interior barrel in asymmetric cross section according to an embodiment of the invention;
Fig. 2 is a part of zoomed-in view of the irregular interior barrel in the asymmetric cross section shown in Fig. 1;
Fig. 3 is the sectional view of the irregular interior barrel in cross section of symmetry according to another embodiment of the invention; With
A part of zoomed-in view of the irregular interior barrel in the cross section that Fig. 4 is the symmetry shown in Fig. 3.
Detailed description of the invention
Fig. 1 is the sectional view according to the irregular interior barrel 1 in the asymmetric cross section of the first embodiment of the present invention, and Fig. 2 is a part of zoomed-in view of the irregular interior barrel in the asymmetric cross section shown in Fig. 1.As shown in Figure 1, the irregular interior barrel 1 in asymmetric cross section comprise there is the first height hf(see Fig. 2) multiple first fin 10 and there is the second height H f(see Fig. 2) multiple second fins 20, wherein the second height H f is greater than the first height hf.Multiple first fin 10 is arranged on the inner surface of interior barrel 1, and is spaced apart from each other, and makes to form the first groove 11 between adjacent two the first fins 10.Similarly, multiple second fin 20 is arranged on the inner surface of interior barrel 1, and is spaced apart from each other, and makes to form the second groove 21 between adjacent two the second fins 20.First fin 10 is parallel to the second fin 20.
As can see from Figure 1, because the height of the second fin 20 to the first fin 10 is high, so when interior barrel 1 is squeezed into the shape in by figure shown in dotted line, second fin 20 will keep space in interior barrel 1, heat transfer medium (such as steam) is made to pass through described spatial flow, that is, this space forms at least one flow channel being used for heat transfer medium, to accelerate the circulation of heat transfer medium.Therefore, the identical interior barrel of fin height in identical with fin height compared with barrel, heat transfer efficiency can be significantly improved, because cannot keep enough space/flow channels when being crushed.
Although Fig. 1 shows be furnished with only one group of first fin 10 and one group of second fin 20 on the inner surface of interior barrel 1, the present invention is not limited to this structure.The irregular interior barrel 1 in asymmetric cross section can have two or more groups first fin 10 and/or two or more groups second fin 20.In addition, the first fin 10 comprised in each group and the quantity of the second fin 20 also can be organized different from other.
According to a preferred embodiment, the outer diameter D of the irregular interior barrel 1 in asymmetric cross section can in the scope of 3mm-16mm, and the thickness Hw of wall 30, in the scope of 0.10mm-0.60mm, makes interior barrel 1 can be arranged in limited space when being crushed.
According to further preferred embodiment, the parameter of the second fin 20 and the second groove 21 limits as follows:
Second height H f:0.10mm-0.30mm of the second fin 20;
The width G f:0.10mm-0.50mm of the second groove 21;
Apex angle α 1:0 °-50 ° of second fin 20;
The quantity of the second fin 20: 5-100.
According to above second fin 20 of restriction and the parameter of the second groove 21, the parameter of the first fin 10 and the first groove 11 can limit as follows:
First height hf:0.01mm-0.15mm of the first fin 10;
The width gf:0.01mm-0.20mm of the first groove 11;
Apex angle α 2:0 °-50 ° of first fin 10;
The quantity of the first fin 10: 1-150.
Although illustrated in Fig. 1 and Fig. 2 that the first all fins 10 has identical height and identical drift angle, and the second fin 20 also has identical height and identical drift angle, the present invention is not limited to this structure.Alternately, the height of the first fin 10 and/or drift angle can be different, and the height of the second fin 20 and/or drift angle can be different.This is also applicable to the first groove 11 and the second groove 21.
Fig. 3 is the sectional view of the irregular interior barrel 1a in cross section of symmetry according to another embodiment of the invention, a part of zoomed-in view of the irregular interior barrel 1a in the cross section that Fig. 4 is the symmetry shown in Fig. 3.As shown in Figure 4, the inner surface of the irregular interior barrel 1a in the cross section of symmetry is provided with two group of first fin 10 and two group of second fin 20.Structure shown in Fig. 3 contributes to the manufacture of interior barrel 1a, this is because so interior barrel is by making pipe drawing by mould, the symmetrical structure of the first fin 10 and the second fin 20 creates symmetrical power on pipe and mould.
Similarly, the parameter of the first fin 10 and the second fin 20 and interior barrel 1a can be above defined in those parameters.In addition, the first fin 10(and the second fin 20) parameter can be different from each other.
In two embodiments described hereinbefore, the first fin 10 and the second fin 20 can extend along the direction of the longitudinal axis being parallel to interior barrel, or extend spirally around the described longitudinal axis of described interior barrel.
Embodiment disclosed herein is exemplary, and should not be construed to restrictive by any way.Scope of the present invention is defined by the claims, and can't help above-described embodiment and limit, and scope of the present invention is intended to the equivalent of the scope comprising claim and is in all deformation programs in right.
