Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail: Fig. 1 is heat exchanger integrated blowing fan assemblying body embodiment 1 schematic representation of the present invention to Fig. 3.
As shown in Figure 1, this heat exchanger integrated blowing fan assemblying body comprises drive motor 1, running shaft 2, fan axle 3, flabellum 4, flabellum cover 10 etc.Running shaft 2 is combined in drive motor 1 rotation.Fan axle 3 forms long cylindrical shape, and is combined on the running shaft 2.On the surface of fan axle 3, use the thermal conductivity good metal to form flabellum 4 from the end to end of fan axle 3.Form the cylindrical shape flabellum cover 10 of hollow around the flabellum 4.
In addition, the inside of flabellum 4 forms snakelike coolant path 5, can make refrigerant moving along the surface current of flabellum 4.Here, though 5 situations about forming at flabellum 4 of coolant path only have been described, also can on flabellum 4 and fan axle 3, form simultaneously.
The other end of running shaft 2 is combined with upper terminal 6 and lower terminal 7.Their supporting rotating shafts 2 rotation, simultaneously, the refrigerant of sending from refrigerant supplying pipe 8 to coolant path 5 entry end water conservancy diversion, from the refrigerant of coolant path 5 outlet end discharge to compressor refrigerant recovering pipe 9 water conservancy diversion.Thereby, during flabellum 4 rotations, also can supply with refrigerant to coolant path 5, prevent the distortion of refrigerant dispatch tube.
Fig. 2 and Fig. 3 show the upper terminal 6 with above-mentioned functions and the structure of lower terminal 7.Upper terminal 6 forms cylindrical rotor 61, and the one end combines with running shaft 2.The center portion of these rotor 61 1 ends forms central bump 62.The central part of rotor 61 forms the 1st refrigerant intake channel 63, is communicated to central bump 62 ends.One end of the 1st refrigerant intake channel 63 is connected with the entry end of coolant path 5.Rotor 61 inside also form the side that the 1st refrigerant discharge tube 64 is communicated to rotor 61.One end of the 1st refrigerant discharge tube 64 is connected with the outlet end of coolant path 5.
In addition, lower terminal 7 comprises stator 71, central groove 78, the 2 refrigerant intake channels 73, the 2 refrigerant discharge tubes 74, bearing 79, structures such as sealing gasket 75-77.Wherein, cylindrical stator 71 inner formation store up tanks 72, can insert the rotor 61 of above-mentioned upper terminal.The central part of storage tank 72 forms spill central groove 78, can insert the central bump 62 of upper terminal 6.Stator 71 inner the 2nd refrigerant intake channel 73 and the 2nd refrigerant discharge tubes 74 of forming.One end of the 2nd refrigerant intake channel 73 is communicated with central groove 78, and the other end is connected with refrigerant supplying pipe 8.One end of the 2nd refrigerant discharge tube 74 is communicated to storage tank 72 inside, and the other end is connected with refrigerant recovering pipe 9.Bearing 79 is contained in storage tank 72 inside, supports the rotation of upper terminal 6 rotors 61.In order to prevent the refrigerant seepage between central groove 78 and storage tank 72 and the bearing 79, at the side face of rotor the 1st, 2,3 sealing gaskets 75,76,77 in conjunction with the oil ring form.
Here, when preventing rotor 61 rotation, the friction of rotor 61 and storage tank 72 inner faces improves the revolving ability of rotor 61, sealing gasket 75,76, and 77 preferably use the manufacturing of magnetic lubriation material.
In addition, when upper terminal 6 is combined in the storage tank 72 of lower terminal 7, form storage receiving part 72a between upper terminal 6 and the storage tank 72, the refrigerant by the 1st refrigerant discharge tube is discharged is discharged to earlier after this storage receiving part 72a, enters into the 2nd refrigerant discharge tube again.
Blowing fan assemblying body action with said structure is as follows:
Running shaft 2 rotations under the effect of drive motor 1, fan axle 3 that is attached thereto and flabellum 4 be rotation together also.At this moment, because of flabellum 4 is shaped as helical, so the air that flows to by flabellum cover 10 1 ends, along the surface of flabellum 4, to the axial screw rotational flow, the other end by flabellum cover 10 discharges at last.
Thereby, by upper terminal 6 and lower terminal 7, can supply with refrigerant to the coolant path of flabellum 4 and fan axle 3, can make air carry out heat exchange through flabellum 4.
If be described in detail, along with the rotation of running shaft 2, the upper terminal 6 of running shaft 2 lower end combinations is in rotation status in the storage tank 72 of lower terminal.
At this moment, the refrigerant by refrigerant supplying pipe 8 is supplied with flow into the 2nd refrigerant intake channel 73 that is positioned at lower terminal 7 central authorities.Then, upper terminal 6 the 1st refrigerant intake channel 63 by being positioned at central groove 78 tops flow in the coolant path 5.At flabellum 4, flow in the coolant path of fan axle 3, with process flabellum 4, the air of fan axle 3 carries out heat exchange.
After in coolant path 5, flow finishing, the refrigerant that outlet end by coolant path 5 is discharged, by the 1st refrigerant discharge tube 64 of upper terminal 6, be discharged to after the storage receiving part 72a of lower terminal 7 storage tanks 72, discharge to refrigerant recovering pipe 9 by the 2nd refrigerant discharge tube 74.The refrigerant of discharging to refrigerant recovering pipe 9 is from newly flowing back to the compressor.
As mentioned above, refrigerant that flows to lower terminal 7 central grooves 78 by the 2nd refrigerant intake channel 73 and the refrigerant of discharging to storage tank 72 storage receiving part 72a by the 1st refrigerant discharge tube 64, by the 1st, 2,3 sealing gaskets 75,76,77 are isolated.
As mentioned above, during flabellum 4 rotation, can be to the coolant path 5 sustainable supply refrigerants of flabellum 4 inside, make air through flabellum 4 surfaces carry out heat exchange after, discharge to the other end.
Thereby, when using the heat exchanger integrated combination of fans body that the invention described above provides, need not establish heat exchanger in addition, therefore can reduce the size of equipment greatly.
Fig. 4 is heat exchanger integrated blowing fan assemblying body the 2nd embodiment's schematic representation of the present invention.Among this embodiment, on the whole surface of blowing fan assemblying body flabellum 4, form many fins made from metal 41.Thereby increase the surface of contact between air and the flabellum 4,, can significantly improve heat exchange performance with this.
Fig. 5 is heat exchanger integrated blowing fan assemblying body the 3rd embodiment's schematic representation of the present invention.In establish the flabellum 4 of coolant path 5, be arranged on form of straight lines on the surface of fan axle 3.The 4th embodiment shown in Figure 6 on blowing fan assemblying body flabellum 4 shown in Figure 6, forms many fins made from metal 41, is used for heat exchange.
Fig. 7 and Fig. 8 are respectively heat exchanger integrated blowing fan assemblying body the 5th embodiment and the 6th embodiment's schematic representation of invention.Among the 5th embodiment, the section configuration undulate of blowing fan assemblying body flabellum 4.Among the 6th embodiment, the shape of blowing fan assemblying body flabellum 4 is spiralitys, and simultaneously, its transverse shape is curved.
Fig. 9 is blowing fan assemblying body the 1st embodiment of the present invention in addition, the example of installing on indoor apparatus of air conditioner.This indoor apparatus of air conditioner has shell 100.Form intakeport 101 and relief opening 102 on the shell.Shell 100 inside possess heat exchanger integrated blowing fan assemblying body of the present invention.Therefore, need not establish heat exchanger in addition and also can carry out indoor temperature control, therefore the size that can significantly dwindle air conditioner.
In the above-mentioned heat exchanger integrated blowing fan assemblying body embodiment explanation, flabellum quantity without limits.Simultaneously, the material of manufacturing flabellum can be the good material of any thermal conductivity.But, preferably use thermal conductivities such as resembling aluminium good, and light material.
