The specific embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the invention clearer; To combine the accompanying drawing in the embodiment of the invention below; Technical scheme in the embodiment of the invention is carried out clear, intactly description; Obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
With Fig. 1～Fig. 4 is that the present invention will be described for example.
As shown in Figure 1, the heat exchange ventilation blower comprises: housing 1, be arranged at return fan 5, pressure fan 9 and heat exchanger 7 in the housing 1.
The two ends of housing 1 have first outlet, 13, second outlet 2 respectively, and the body of housing 1 has the 3rd outlet (not shown), and it is first isolation part 01 and second isolation part 02 of three sub spaces that set inside has the spatial division in the housing 1.Three sub spaces comprise the subspace at first outlet, 13 places, the subspace at the subspace at second outlet, 2 places and the 3rd outlet (not shown) place.
Wherein, first outlet 13 is an air outlet, and second outlet 2 is a return air inlet.
Return fan 5 is between second outlet 2 of second isolation part 02 and housing 1.
The first air-supply dividing plate 011, the second air-supply dividing plate 012 and the 3rd air-supply dividing plate 013 that first isolation part 01 comprises successively that head and the tail connect; The first air-supply dividing plate 011, the 3rd air-supply dividing plate 013 are parallel with air flow direction; The second air-supply dividing plate, 012 air flow direction is vertical; The end that the first air-supply dividing plate 011, the 3rd air-supply dividing plate 013 deviate from the second air-supply dividing plate 012 is fixed on the inwall of housing 1; The second air-supply dividing plate 012 has first through hole 0121 that the air outlet with pressure fan 9 is complementary; Pressure fan 9 is arranged on the second air-supply dividing plate 012, and the air outlet of pressure fan 9 is buckled on first through hole 0121, and the first air-supply dividing plate 011 is between first outlet 13 of pressure fan 9 and housing 1.The inwall of the first air-supply dividing plate 011 and the second air-supply dividing plate 012 and housing 1 forms pressure fan chamber 8.
The subspace at first outlet, 13, second outlet, 2 places of housing 1 or the subspace at first outlet, 13 and second outlet, 2 places can be provided with baffle plate.
As shown in Figure 1, the subspace at first outlet, 13 places of housing 1 is provided with air-supply static pressure chamber baffle plate 15.The both sides of the static pressure of blowing chamber baffle plate 15, the first air-supply dividing plate 011 all post acoustical cotton 14 towards the inwall of the housing 1 that hold at a side and first outlet, 13 places of first outlet 13, with further reduction noise.
Wherein, air-supply static pressure chamber baffle plate 15 is the first air-supply dividing plate 011 and second extension that a end that dividing plate 012 is connected has of blowing, and has the gap between the inwall of the afterbody of extension and housing 1.The inwall that air-supply static pressure chamber baffle plate 15 and second is blown dividing plate 012, the 3rd air-supply dividing plate 013 and housing 1 forms air-supply static pressure chamber 12, and the inwall that belongs to the housing 1 of end with first outlet 13 forms wind pushing cavity 19.
As shown in Figure 2; Second outlet of return fan 5 and housing 1 also is provided with return air static pressure chamber baffle plate 16 between 2, and the inwall that an end of return air static pressure chamber baffle plate 16 is arranged on housing 1 is provided with a side of the first return air dividing plate 021, has the gap between the inwall of the other end and housing 1; So that air-flow baffle plate 16 circulations that get into from second outlet 2 along return air static pressure chamber; Prolong the circulation path of air-flow, arrow path Y as shown in Figure 2, and air-flow played barrier effect; The energy of attenuating noise effectively reaches the purpose of reducing noise.
The exit of the exit of the exit of first through hole 0121, second through hole 0221 or first through hole 0121 and second through hole 0221 all can be provided with abatvoix.Abatvoix can be the herringbone orifice plate, and the tip of herringbone orifice plate is towards first through hole 0121, second through hole 0221 or first through hole 0121 and second through hole 0221.
As shown in Figure 3, the exit of first through hole 0121 and second through hole 0221 is provided with herringbone orifice plate 17, is used for air-flow and return fan 5 that pressure fan 9 is discharged through first through hole 0121 are passed through the air-flow that second through hole 0221 is discharged; Shunt in the outside along herringbone orifice plate 17; Air-flow after the shunting has prolonged the circulation path of air-flow along arrow Z circulation, has effectively weakened the energy of noise; And herringbone orifice plate 17 itself has the effect of absorption noise, thereby greatly reduces noise.
Abatvoix also can be at least one parallel sound-absorbing deflector, and parallel sound-absorbing deflector is parallel with the second air-supply dividing plate 012 or the second return air dividing plate 022.Parallel sound-absorbing baffle surface also can be posted acoustical cotton 14, with further reduction noise.
As shown in Figure 4, air-supply static pressure chamber baffle plate 15 vertically is connected with parallel sound-absorbing deflector 18, the three air-supply dividing plates 013 side vertical be connected with another piece parallel sound-absorbing deflector 18 relative with the static pressure chamber baffle plate 15 of blowing; Two parallel sound-absorbing deflectors 18 are parallel to each other staggered; Be positioned at the below of first through hole 0121, the air-flow that first through hole 0121 is discharged stops, makes air-flow W circulation along the arrow path; Reduced the flow velocity of air-flow; Weaken the energy of noise effectively, prolonged the path of air-flow, played the effect that reduces noise.
Similarly, be provided with two staggered parallel sound-absorbing deflectors 18 that are parallel to each other in the return air static pressure chamber 6, be positioned at the exit of second through hole 0221; The air-flow that second through hole 0221 is discharged stops; Make air-flow W circulation, reduced the flow velocity of air-flow, weakened the energy of noise effectively along the arrow path; Prolong the path of air-flow, played the effect that reduces noise.
The heat exchange ventilation blower that the foregoing description provides is cut apart the space of heat exchange ventilation blower through first isolation part and second isolation part, has optimized the structure of enclosure interior, has improved the heat exchange performance of ventilating; Through the baffle plate that is provided with in the housing, the air-flow that circulates has been played barrier effect, weakened noise energy effectively, increased the length of noise channel, reached the purpose that reduces noise, and, for being set in the passage, more acoustical cotton created condition.Further, acoustical cotton is set in the housing, when reducing noise, has also forcibly changed the flow direction of air-flow, further weakened the energy of noise, increased the noise reduction of baffle plate, reduced noise.
What should explain at last is: above embodiment is only in order to explaining technical scheme of the present invention, but not to its restriction; Although with reference to previous embodiment the present invention has been carried out detailed explanation, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these are revised or replacement, do not make the spirit and the scope of the essence disengaging various embodiments of the present invention technical scheme of relevant art scheme.
