The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in further detail.
Shown in Fig. 1～4, the present invention includes support 1 and dew point heat exchange movement 2, as Fig. 4, dew point heat exchange movement 2 by several heat exchange units 3 in turn in abutting connection with constituting, each heat exchange unit 3 is separated also the humid air passage 5 of adjacency in turn by dividing plate 4, hot media channel 6, humid air passage 5 and dry air passage 7 constitute, that is to say, the passage permutation and combination of dew point heat exchange movement 2 is a humid air passage 5, hot media channel 6, humid air passage 5, dry air passage 7, humid air passage 5, hot media channel 6, humid air passage 5, dry air passage 7 ... the multichannel dew point heat exchange movement 2 of arranging thus and constituting, its hot media channel 6 both sides are humid air passage 5, and the both sides of dry air passage 7 are similarly humid air passage 5.Be provided with 2 layers of horizontal laminate 8 in the hot media channel 6, (not drawing in the drawings) sealed with strip of paper used for sealing in the both sides up and down of hot media channel 6, horizontal laminate 8 constitutes the runner (Fig. 2 B) that comes and goes baffling with the end socket 9 at dew point heat exchange movement 2 two ends, the orlop runner connects medium inlet joint 10, the superiors' runner connects media outlet pipe joint 11, at least should be provided with 1 layer of horizontal laminate 8 in the hot media channel 6, quantity is set determines according to actual needs of horizontal laminate 8, in the present embodiment, be provided with the serrated fin 15 of vertical direction in the hot media channel 6, the thermal medium of bottom horizontal flow sheet flows through from the slit of serrated fin 15, and serrated fin 15 can improve the heat exchanger effectiveness of thermal medium in the hot media channel 6.Be provided with the fin 12 of vertical direction in the humid air passage 5, in the present embodiment, fin 12 is a rippled fin.The dividing plate 4 of dry air passage 7 both sides is provided with several apertures 13 that is communicated with humid air passage 5, the both sides of dew point heat exchange movement 2 bottoms are provided with dry air inlet connector tube 14(Fig. 3 A, 3B), dry air passage 7 connects dry air inlet connector tube 14, seal by strip of paper used for sealing around the dry air passage 7, dry air enters dry air passage 7 from dry air inlet connector tube 14, and aperture 13 enters humid air passage 5 from the dry air passage 7 both sides dividing plates 4, in the present embodiment, be provided with the serrated fin 16 of vertical direction in the dry air passage 7, the dry air that enters dry air passage 7 is flowed from the bottom up, and aperture 13 enters humid air passage 5 from the dry air passage 7 both sides dividing plates 4, and serrated fin 16 improves the heat exchanger effectiveness of dry air in the dry air passage 7.
