Detailed description of the invention
Referring to Fig. 3～5 Suo Shi to the heat exchanger for air-conditioning of the present invention and air-conditioning
Detailed description of the invention be described in detail.
Dash forward as it is shown on figure 3, form multiple crack on fin 1 between adjacent heat exchange pore 2
Playing 3, this multiple cracks projection 3 be arranged in parallel, and it is whole relative to the side of fin 1
11 are obliquely installed.As shown in Figure 4, the angle between air intake direction and side 11 be θ 1 (i.e.
θ 1 in Fig. 1 and Fig. 2), crack projection 3 is relative to side 11 along clockwise direction
Tilting, the angle between this crack projection 3 and side 11 is set to θ 2, this θ 2 is more than 0
Degree, less than π-2 θ 1, makes the angle between crack projection 3 and air intake direction be consistently greater than θ 1.
As it is shown in figure 5, employing said structure, due to the folder between crack projection 3 and air intake direction
Angle is consistently greater than θ 1, makes the slit formed by crack projection 3 be perpendicular on air intake direction
Projected area increase (L2 be more than L1), increase accordingly formed gas channel
Incoming air area, it is possible to accelerate the circulation of gas, is conducive to improving the heat exchange efficiency of heat exchanger,
Thus improve the performance of air-conditioning.
Meanwhile, the angle (θ 1+ θ 2) between crack projection 3 and air intake direction is more than 45
Degree is less than 135 degree, it is possible to ensure that the slit formed by crack projection 3 is being perpendicular to air intake
Projected area on direction is more than its projected area on air intake direction, is conducive to accelerating gas
The circulation of body.Especially, when θ 1 and θ 2 sum are 90 degree, crack projection 3 is perpendicular to
Air intake direction, the incoming air area of the gas channel now formed is maximum.
It addition, as shown in Figure 4, by the folder between connecting portion and the side 11 of crack projection 3
Angle is set to θ 3, then this θ 3 and θ 1 is equal, i.e. connecting portion place plane is put down with air intake direction
OK.As it is shown in figure 5, employing said structure, connecting portion is made to be perpendicular on air intake direction
Projected area minimizes, it is possible to avoids connecting portion to stop gas flowing, helps speed up gas
Body circulates, and is conducive to improving the heat exchange efficiency of heat exchanger, thus improves the performance of air-conditioning.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention,
All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement made
Deng, should be included within the scope of the present invention.
Such as, in the above-described embodiments, as shown in Figure 4, the connecting portion place of crack projection 3
Plane parallel with air intake direction (i.e. θ 3 equal to θ 1), now, connecting portion be perpendicular to into
Projected area on wind direction is minimum (as shown in (B) in Fig. 5).But be not limited to
This, as shown in Figure 4, by the angle between plane perpendicular for side 11 and air intake direction
Being set as θ 4, the angle between plane and the air intake direction paralleled with side 11 is θ 1,
And θ 1 is 90 degree with θ 4 sum, when connecting portion place plane and the air intake of crack projection 3
When angle between direction is less than θ 4 (i.e. pi/2-θ 1), with connecting portion place plane and side
Limit 11 is vertically compared, it is also possible to the connecting portion reducing crack projection 3 to a certain extent is hanging down
Straight projected area on air intake direction.
