Accompanying drawing explanation
Fig. 1 is the utility model structural representation
Fig. 2 is heat exchanger structure schematic diagram in the utility model
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
As shown in Figure 1, the utility model comprises a housing 1, and housing 1 both sides arrange respectively an air inlet 11 and an air outlet 12, in housing 1, sets gradually fillter section 2, one preheating section 3, one fan section 4, one bringing-up section 5, one noise reduction sections 6 along air inlet 11.
As Fig. 1, shown in Fig. 2, the interior heat exchanger 8 that arranges respectively of preheating section 3 and bringing-up section 5, the upper end delivery port of heat exchanger 8 arranges a upper condensate sump 81, the lower end water inlet of heat exchanger arranges a lower condensate sump 82, number row heat exchanger tube 83 arranged side by side is set between upper condensate sump 81 and lower condensate sump 82, upper condensate sump 81 provides the water return outlet of the source pump of low-temperature heat source by a hot outlet tube road 84 external, upper condensate sump 81 tops arrange an air bleeding valve 86, lower condensate sump 82 connects the feed water inlet of source pump by a hot inlet pipe road 85, lower condensate sump 82 bottoms arrange a draining valve 87, the inner heating agent of filling of heat exchanger 8.Enter lower condensate sump 82 through the heating agent after source pump heating by hot inlet pipe road 85, by the rear heat exchanger tube 83 that evenly enters of lower condensate sump 82, discharged by hot outlet tube road 84 after then entering upper condensate sump 81, return to source pump and reheat.
