Cause a high, volume greatly, air draft is not smooth.（3）Volume is heavy, and transport and installation are inconvenient, does not adapt to especially pacify on window
Dress is used.
The content of the invention
The invention aims to overcome the deficiencies in the prior art there is provided a kind of volume compact, UTILIZATION OF VESIDUAL HEAT IN fully, wind
A kind of new blower fan that road is ingenious in design, cost is low, be easily installed.
The present invention is achieved by the following technical programs：
A kind of new blower fan, including casing, heat exchanger, filter, pressure fan, exhaust blower, it is characterised in that the air-supply
The outlet of machine is connected with heat exchanger, is provided with flow-guiding structure in the heat exchanger, and the flow-guiding structure is by the new of heat exchanger
Wind side is isolated into some sections, and fresh air side of the fresh air that pressure fan is sent by isolation is got in into " S " type from fresh air outlet.
Further, be provided with the heat exchanger with the staggered air draft side in fresh air side, air draft side one end with
Exhaust blower be connected, the other end of the air draft side is communicated with exhausting duct, the exhausting duct along casing periphery setting, and with casing
The air draft entrance in portion is communicated, and the exhausting duct is hollow-core construction, it is ensured that air draft is unimpeded, and plays heat-blocking action.
Further, the pressure fan, exhaust blower use the ultrathin centrifugal fan with closed impeller, described close
Double shrouded wheel by non-porous wheel plate and be arranged on wheel plate edge in centrifugation shape blade constitute.
Further, cleaning module is provided with the casing, the cleaning module is by the filter being mounted side by side and air-supply
Machine is constituted, and the filter is one or more combinations in low efficient filter, medium effeciency filter, high efficiency particulate air filter.
Further, the cleaning module is Demountable, buckle or bolt or activity by way of inlaying
In casing.
Further, the casing is provided with a bypass valve, and the bypass valve is communicated with the outlet of pressure fan.
The present invention has following technique effect：
The present invention solves that existing new blower fan UTILIZATION OF VESIDUAL HEAT IN is insufficient, heat exchanger effectiveness is low, Duct design is unreasonable, volume
Greatly, arrangement is optimized to heat exchanger, casing and air channel in the problem of installing inconvenience, the present invention, dexterously by air channel and heat
Exchanger, casing are combined as a whole, using the heat exchanger with flow-guiding structure and with the ultrathin centrifugal of closed impeller
Blower fan, and detachable module combining structure is applied, fresh air is carried out sufficient heat exchange with air draft, eliminate heat exchange dead
Angle, improves utilization rate of waste heat, and significantly reduces the volume of the whole new blower fan of flow guiding type, improves the convenience installed and safeguarded
Property, while simplifying manufacturing process, reduce production cost.
The exhausting duct of the present invention is set along internal side of shell periphery in hollow-core construction, has on the one hand played thermal insulation layer.Work as the winter
During the season relatively low and higher indoor temperature of outdoor temperature, exhausting duct can prevent condensed water from being condensed in casing outer surface as thermal insulation layer.
When summer outdoor temperature is higher, and interior be provided with air-conditioner temperature it is relatively low when, exhausting duct can effectively prevent outdoor as thermal insulation layer
Temperature passes to interior, can reduce air conditioner energy source consumption；On the other hand, exhausting duct makes air draft and fresh air formation countercurrent heat exchange, then
" S " the type fresh air side design isolated plus flow-guiding structure, greatly improved heat exchanger effectiveness, and energy conservation and consumption reduction effects significantly, make new
Wind and the heat exchange that air draft is carried out are more abundant, improve utilization rate of waste heat, and reduce the volume of whole new blower fan.
The casing of the present invention is provided with a bypass valve, and the bypass valve is communicated with the outlet of pressure fan.In transition season, when
When the temperature difference of indoor and outdoor is little, heat exchange has little significance, and at this moment can manually or automatically open bypass valve, outdoor air is directly led to
Cross filter, pressure fan feeding indoor, without over-heat-exchanger, reduce fan resistance, increase air output, while also reducing
The energy consumption present invention is simple in construction, and volume compact is easy for installation, and adaptability is good, can a tractor serves several purposes.

Embodiment
Invention is described in detail with reference to the accompanying drawings, but the present invention is not limited to following embodiments.
As shown in Figure 1 and Figure 2, a kind of new blower fan, including casing 14, heat exchanger 7, filter 12, pressure fan 2, exhaust blower
8。
Casing 14 is made using metal, plastics, wood-based plate or other materials, and cleaning module is provided with casing 14, described net
Change module be made up of the filter 12 and pressure fan 2 being mounted side by side, the filter 12 be low efficient filter, medium effeciency filter,
One or more combinations in high efficiency particulate air filter.Cleaning module is Demountable, by buckle or bolt or is inlayed
Mode is movably arranged in casing 14.In manufacture or maintenance process, filter 12, air-supply can be quickly and easily installed or removed
Machine 2 or whole cleaning module.
Pressure fan 2 uses the ultrathin centrifugal fan with closed impeller, and the closed impeller is by non-porous wheel plate
And it is arranged on blade composition of the wheel plate edge in centrifugation shape.This ultrathin centrifugal fan with closed impeller has noise
Small, resistance is small, small volume, high-power advantage, and is mounted side by side with filter 12, is effectively reduced volume, saves space, carries
Height transport and convenience, the adaptability installed.Fresh air inlet 11 is additionally provided with casing 14, outdoor fresh air enters from fresh air inlet 11
In casing 14, first pass around multistage filter 12 and filtered, enter back into the pressure fan 2 being arranged side by side with multistage filter 12,
Then the top of casing 14 is entered by pressure fan outlet 4.
The top of casing 14 is provided with heat exchanger 7, exhaust blower 8, and the exhaust blower 8 is arranged on the side of heat exchanger 7.Heat exchange
Device 7 can use heat-exchangers of the plate type or tubing heat exchanger, and the heat exchanger 7 of the present embodiment preferentially uses aluminum plate type heat exchange
Device, is rearranged by multilayer fresh air side and air draft top-cross mistake, so that heat exchange and waste heat must be utilized.As shown in figure 1, heat exchange
Flow-guiding structure is provided with the fresh air side of device 7, the flow-guiding structure is made up of fresh air wind deflector 5, fresh air wind-guiding adhesive tape 6.It is described new
Wind wind-guiding adhesive tape 6 is pasted onto in the fresh air side of heat exchanger 7, is arranged in parallel in multiple tracks, and the fresh air side of heat exchanger 7 is isolated into
Some sections, the fresh air wind deflector 5 is in diagonally-installed at pressure fan outlet 4 and fresh air outlet 9, and make that pressure fan 2 sends is new
Fresh air side of the wind by isolation is got in into " S " type from fresh air outlet 9.It is provided with and is staggered with fresh air side in heat exchanger 7
Air draft side, the air draft side is communicated with being arranged on the exhausting duct 3 of the inner side of casing 14.
Exhausting duct 3 is set along the periphery of casing 14, and is communicated with the air draft entrance 1 of the bottom of casing 14, and the exhausting duct 3 is sky
Core structure, it is ensured that air draft is unimpeded.Exhausting duct 3 can be the exhaust duct or hollow edge set along the inner side of casing 14
The sandwich set on the inside of the periphery of casing 14.The exhausting duct 3 of the present embodiment preferentially uses what is set along the inside parallel of casing 14
