It can be arc or linear to connect section 21 and the 3rd linkage section 23.Formed between the linkage section 22 of first linkage section 21 and second
It is angled, angle is also formed between the linkage section 23 of the second linkage section 22 and the 3rd, so as to make drainage plate 20 that there is approximation
The form of arc.
It should be noted that first linkage section 21 is circular arc, first linkage section 21 of circular arc is formed
The center of circle is away from the water pipe hole 30, and the radius for forming first linkage section 21 of circular arc is less than the radius in water pipe hole 30.
In the present embodiment, the diameter L for the circular arc that first connection end 21 is formed is 8mm.First linkage section 21 of circular arc
It can be obtained by flanging bore of the prior art, the setting of circular arc is smaller to the flow resistance of heat smoke, it is ensured that hot cigarette
The velocity of liquid assets of gas.
Continue referring to Fig. 2, the minimum spacing between the water pipe hole 30 of 22 adjacent setting of the second linkage section is small
In 5mm, second linkage section 22 is less than with the angle in face of water pipe hole side that the 3rd linkage section 23 is formed more than 120 degree
135 degree.In the present embodiment, the spacing H between the hole wall of water pipe hole 30 of 221 adjacent setting of the first linkage section is
The angle that 4.5mm, the extension line of second linkage section 22 and the 3rd linkage section 23 are formed is 38 degree, second linkage section 22
Length be 8mm, a diameter of 15mm in the water pipe hole 30.Such setting, excessive spacing can be prevented and cause heat exchange to imitate
Rate is relatively low, it also avoid the excessive area occupied of drainage plate 20, improves the heat exchange area of heat smoke, further ensure that hot cigarette
The heat exchange efficiency of gas and water pipe.
Further, the drainage plate 20 is two, and two mirror images of drainage plate 20 are set.It refer to Fig. 2, two institutes
The structure that drainage plate 20 connects into a closing is stated, to prevent heat smoke from producing vortex group.
It is to be appreciated that heat exchanger fin includes at least two water pipe holes 30, two drainage plates 20 that mirror image is set are located at two
Between water pipe hole 30.In the present embodiment, the water pipe hole 30 is five, and five water pipe holes 30 are set in two rows, wherein two
The individual water pipe hole 30 is located at first row, and its excess-three water pipe hole 30 is located at second row, and a water pipe of first row
The center of circle in hole 30 is located on the center line of two adjacent circle center line connectings of water pipe hole 30 of second row, this to shift to install so that water
Pipe also serves drainage to heat smoke, ensures the heat exchange area of heat smoke and water pipe.At two water pipe holes 30 of first row
In the downstream of heat smoke flow direction, mirror image set two drainage plates 20 located at first row two water pipe holes 20 it
Between, also heat smoke can be just drained to the first drainpipe in face of the side of exhaust end, it is ensured that the heat exchange of water pipe and heat smoke effect
Rate.
Further, the substrate 10 is additionally provided with flanging bore, and the drainage plate 20 is located at the bore edges of flanging bore, Huo Zheke
To be interpreted as the side that drainage plate 20 is exactly flanging bore.
