Embodiment one
As shown in Figs 1-4, a kind of spiral fin coil provided in this embodiment is mounted in gas heater or wall-hung boiler,
Including tube body 100 and with 100 integrally formed fin 200 of the tube body；The fin 200 is along 100 axis direction of the tube body
It is arranged in the shape of a spiral in the outer surface of the tube body 100；200 surface of the fin is provided with multiple breaches 300, multiple described to split
Mouth 300 is arranged in the shape of a spiral along 100 axis direction of the tube body；The width of the breach 300 is sequentially increased from bottom to top.
Compared with prior art, technical advantage possessed by a kind of spiral fin coil provided in this embodiment is：
The spiral fin coil of the present embodiment, since fin 200 and tube body 100 are arranged using integrated molding, there is no wings
The phenomenon that piece 200 and 100 failure welding of tube body, heat exchange efficiency can reach requirement when use, between fin 200 and tube body 100
No-welding-spot, thermal contact resistance is small, can improve heat exchange efficiency；
The spiral fin coil of the present embodiment, when burning, since there are multiple breaches 300 on fin 200 so that phase
Air circulation is more preferable between adjacent fin 200, and combustion space is big, forms the three dimensions of flowing, and burning is more abundant so that
The transmission of heat is more direct, and heat exchange efficiency further increases；
The spiral fin coil of the present embodiment, since the width of breach 300 is sequentially increased from bottom to top, rather than using same wide
The breach 300 of degree can also reduce the area of breach 300 on the basis of improving combustion flows, ensure the face of fin 200
Product will not significantly reduce.
Specifically, it is described in detail below for each structure of spiral fin coil in the present embodiment：
In the alternative of the present embodiment, in the alternative of the present embodiment, between the top and root of the fin 200
Distance be 5-15mm.
In the alternative of the present embodiment, the distance between the bottom of the breach 300 and 200 root of the fin are
1-5mm.
In the first alternative of the present embodiment, please continue to refer to Fig. 4, the breach 300 uses inverted triangle breach
300.The inverted triangle breach 300 includes tip 310 and the fluting portion 320 positioned at 310 both sides of the tip, two fluting portions
320 bottoms are crossed to form tip 310, and top extends respectively to intersect with 200 surface of fin, and each fluting portion 320 respectively with
200 solid object surface of fin constitutes obtuse angle.During burning, if 200 surface of fin is without breach 300, flame is respectively two
It burns between a fin 200, since fin 200 itself has certain thickness, can cause to burn so insufficient, exchange heat
It is insufficient, therefore open up breach 300 so that it burns between all fins 200 abundant, if however, breach 300 occupies proportion mistake
Greatly, then 200 area of fin can be reduced accordingly, it is thus possible to heat exchange efficiency can be caused to reduce, to reduce 300 area of breach, because
This sets breach 300 to the structure that bottom is tip 310, and open top is bigger, can flame fully be circulated, this conjunction
The setting of physics and chemistry can further increase the heat exchange efficiency of spiral fin coil.
In second of alternative of the present embodiment, the breach 300 is using inverted trapezoidal breach 300.
In the alternative of the present embodiment, the spiral angle of the breach 300 is 5 ゜ -26 ゜.
In the alternative of the present embodiment, the tube body 100 uses copper pipe.
In the alternative of the present embodiment, the thickness of the fin 200 is 0.2-0.8mm.The thickness of the tube body 100
For 0.6-1.2mm
In the alternative of the present embodiment, the screw pitch of the fin 200 is 1.5-5mm.
