Related content in technique scheme is explained as follows:
1. in such scheme, on the lamellar body of described spoiler, there is " the flow-disturbing face of indent arcuation ", design whereby, make in the time that air enters, the dust of described spoiler in not only can blocks air, reduces it and enters air channel, more can produce a flow-disturbing on the surface that approaches this ripple floor by the design of this specific indent arcuation flow-disturbing face, make dust be difficult to landing, and then significantly reduce the accumulation of dust.
2. in such scheme, described flow-disturbing hole connects the tow sides of this ripple floor and offers, and to strengthen even increasing the generation of described flow-disturbing, coordinates the design of described spoiler, further reduces the accumulation of dust on ripple floor surface.
3. in such scheme, the angle between lamellar body and the air channel of described spoiler is 20～70 degree, to stop how airborne dust and produce more effectively flow-disturbing in facilitating air to enter air channel.
4. in such scheme, the angle between lamellar body and the air channel of described spoiler is 30～60 degree.
5. in such scheme, described spoiler and flow-disturbing hole are between the air intake vent and left window of described ripple floor, between described left window and right window, all respectively arrange two pairs between described right window and the air outlet of described ripple floor.
Operation principle of the present utility model and advantage are as follows:
A kind of air heat exchanger fin of the utility model arranges in pairs spoiler and flow-disturbing hole on described fin along air channel; Wherein, the most of dust of spoiler in not only can blocks air enters air channel, more can produce a flow-disturbing on the surface that approaches this ripple floor by the unique design of indent arcuation flow-disturbing face on its lamellar body, make dust be difficult to landing, and then significantly reduce the accumulation of dust; In addition, described flow-disturbing hole connects the tow sides of this ripple floor, to strengthen even increasing the generation of described flow-disturbing, coordinates the design of described spoiler, further reduces the accumulation of dust on ripple floor surface; The utility model contrast prior art, can ensure still possess good heat exchange property after the long-term use of heat exchanger, and the Energy Efficiency Ratio of system is improved; In addition, owing to having reduced the accumulation of dust, reduce the wash number of heat exchanger, the service life of also having improved heat exchanger simultaneously.
