The surface of the fin is provided with oblique flanges symmetrical along the casing ring axial line, edges on two sides of the flange are provided with notches, and the notches do not separate all the flanges. The notches are distributed in up-down symmetry by a connecting line of center points of two adjacent casing rings, and in left-right symmetry by a vertical line at the mid-point of the connecting line of the center points of the two adjacent casing rings. The tube fin type heat exchanger can effectively increase heat exchanging efficiency of the fins.
Description
Technical field
The present invention relates to a kind of idle call heat exchanger, relate in particular to a kind of tube-fin type heat exchanger for air conditioner.
Background technology
Development along with society, the energy-efficient performance requirement of people's heat exchanging device is more and more higher, idle call heat exchanger caliber is 9.53mm, 7mm develops to tubule footpath direction, when people directly are transformed into 5mm caliber or littler caliber to caliber from 7mm, and when used fin not being carried out again development and Design, its heat exchange property often reaches and does not require.
Summary of the invention
At the shortcoming of prior art, the purpose of this invention is to provide a kind of tube-fin type heat exchanger for air conditioner that can effectively improve the heat exchange efficiency of fin.
For achieving the above object, technical scheme of the present invention is: a kind of tube-fin type heat exchanger for air conditioner, comprise some collars that are arranged in parallel and the fin that axially is provided with along the collar, fin surface is provided with along the symmetrical oblique flange of collar axial line, the edge of flange both sides is provided with breach, and breach does not separate all flange.
Breach is symmetrical distribution up and down with the line of adjacent two collar central points, reaches the vertical line left-right symmetry distribution with the line mid point of adjacent two collar central points.
This collar comprises ring wall and bottom, and the ring wall lower end is provided with first fillet that is connected with the bottom transition.There is second fillet upper end of ring wall toward the collar outside.Also be connected with stepped annular transition structure between ring wall and the bottom.
The internal diameter of ring wall is D1=5 ± 1mm, and the one-sided width of annular transition structure is E=0.8～1.5mm, and the internal diameter of annular transition structure is D2=D1+2E, and every flange two ends are R3=(1/2) D2+0.8～1.5 near the beeline at collar center.
Height h1=1.1～the 1.6mm of ring wall, the height h2=0.1～0.3mm of annular transition structure, the radius R 1 of first, second fillet, R2 are 0.2～0.4mm, fin width Pw=11mm, adjacent collar centre-to-centre spacing Pt=19mm.The flange quantity of fin one side of something is 4～8, and the L=1.0～1.5mm of projection width of the relative horizontal plane of flange, flange height h3=0.4～0.8mm.This breach extends y1=1～2mm inwards by outer side flanging edge, and the transverse width y2=1～3mm of this breach.
Compared with prior art, the present invention becomes big by oblique flange is set, makes the flow through resistance of this regional air-flow at fin surface, makes air-flow be subjected to good disturbance, has improved heat exchange efficiency.Owing to be provided with breach at the edge of flange both sides, the breach at fin bar seam middle part can not be excessive, particularly can not all be divided into two sections to all bar seams, so just make whole fin surface more even to the resistance of air-flow, air-flow also can be subjected to good disturbance in this zone, so heat exchange efficiency also is improved.

The specific embodiment
The present invention is described in further detail below in conjunction with accompanying drawing.
A kind of tube-fin type heat exchanger for air conditioner as shown in Figure 1, comprise some collars that are arranged in parallel 1 and the fin that axially is provided with along the collar 1, fin surface is provided with along the symmetrical oblique flange 2 of the collar 1 axial line, and the edge of outer side flanging 2 is provided with breach 3, and breach 3 does not separate all flange 2.Wherein, fin width Pw=11mm, the adjacent collar 1 centre-to-centre spacing Pt=19mm.This breach 3 is symmetrical distribution up and down with the line of adjacent two collar 1 central points, reaches the vertical line left-right symmetry distribution with the line mid point of adjacent two collar 1 central points.
This breach 3 extends y1=1～2mm inwards by outer side flanging 2 edges, and the transverse width y2=1～3mm of this breach 3, y1=1.2mm in the present embodiment, y2=1.5mm.
The zone of above-mentioned breach 3 can not be excessive, particularly can not all be divided into two sections to all flange 3, that is to say that y1 is little.If breach 3 has run through all flange 2, so just form the passage that resistance is little at fin surface, air-flow also can directly pass from here, is not subjected to good disturbance, can cause heat exchange efficiency poor.In order to make breach 3 zones possess bigger resistance, make the air-flow that flows through obtain good disturbance, breach 3 can not separate all flange 2.
This collar 1 comprises ring wall 4 and bottom 5 as shown in Figure 2, and to be provided with the first fillet R1 that is connected with bottom 5 transition be 0.2～0.4mm in ring wall 4 lower ends, and R1 is 0.3mm in the present embodiment.The internal diameter of ring wall 4 is D1=5 ± 1mm, the height h1=1.1～1.6mm of ring wall 4, h1=1.2mm in the present embodiment.Every flange 2 two ends are near the beeline at the collar 1 center, and promptly to extend to the collar 1 center be the center of circle to flange 2 length, and radius is the rounded edge of R3, R3=(1/2) D1+1.6～3.0 wherein, present embodiment, R3=4mm.
As shown in Figure 6, the flange quantity of fin one side of something is 4, and the L=1.0～1.5mm of projection width of flange 2 relative horizontal planes, flange 2 height h3=0.4～0.8mm.In the present embodiment, L=2mm, h3=0.6mm.
As shown in Figure 3, the structure of present embodiment is similar to embodiment 1, and its difference is: there is second fillet upper end of ring wall 4 toward the collar 1 outside, and the radius R 2 of this second fillet is 0.2～0.4mm also, and in the present embodiment, R2 is 0.3mm.
As shown in Figure 4, the structure of present embodiment is similar to embodiment 1, and its difference is: also be connected with stepped annular transition structure 6 between ring wall 4 and the bottom 5.Height h2=0.1～the 0.3mm of annular transition structure 6, its one-sided width is E=0.8～1.5mm, the internal diameter of annular transition structure 6 is D2=D1+2E, h2=0.2mm in the present embodiment, E=0.8mm, D2=6.8mm.Near beeline R3=(1/2) D2+0.8～1.5 at the collar 1 center are arrived at every flange 2 two ends, in the present embodiment, and R3=4.5mm.
As shown in Figure 5, the structure of present embodiment is similar to embodiment 3, and its difference is: there is second fillet upper end of ring wall 4 toward the collar 1 outside, and the radius R 2 of this second fillet is 0.2～0.4mm also, and in the present embodiment, R2 is 0.3mm.
As shown in Figure 7, this fin-tube type heat exchanger can form two rows, three row or more row's fins in the longitudinal direction expansion with fin of the present invention in actual applications, also can with other traditional fins, be that 7mm, 9.53mm etc. are combined to form two rows, three row or more row's fins as fin cover ring diameter.
