Specific embodiment
In order that technological means, creation characteristic, reached purpose and effect that the present invention is realized are easy to understand, tie below
Conjunction is specifically illustrating, and the present invention is expanded on further.
As shown in figure 1, a kind of efficiently small temperature difference heat exchange end, including housing 1, the front end of housing 1 is provided with air outlet 2, goes out
Air cleaner 3 is provided with air port 2, the side of housing 1 is provided with air inlet 4, and being provided with fin between air inlet 4 and air outlet 2 changes
Hot device 5.
As shown in Fig. 2 finned heat exchanger 5 is made up of fin 501 and pipeline 502, fin 501 is using windowing aluminum fin-stock, pipe
Road 502 uses inner screw thread copper pipe, rational heat exchange area to be conducive to improving heat exchange efficiency.Finned heat exchanger 5 is connected with through-flow wind
Machine 6, the exit of cross flow fan 6 is connected with diversion air duct 7.During work, cold-hot wind from air inlet 4 via finned heat exchanger 5 from
Air outlet 3 sheds.The lower section of finned heat exchanger 5 is provided with water-collecting tray 8, the Pan Kou of water-collecting tray 8 is in horizontal level, and water-collecting tray 8 is tried to get to the heart of a matter
To be obliquely installed, and discharge outlet 10 is provided with the lowest part tried to get to the heart of a matter, such waste water would not be stockpiled, prevented in water-collecting tray 8
Fan coil units drainage is stopped.
