Description
Technical field:
The utility model relates to a kind of centrifugal blower of dual-spiral sprue, and it belongs to centrifugal blower field.
Background technique:
Centrifugal blower is because its rotating speed is high, volume is little, high-power feature, and in running, the heating of motor is very large.For low power type, the air-cooled mode of Blower Housing can be adopted to dispel the heat to it, in prior art, a kind of air-cooled method of Blower Housing as shown in Figure 1, it by arranging radiating fin 1 on Blower Housing, after cooling-air enters into Blower Housing, taken away the heat in motor by radiating fin, and then reduce the heat of whole motor.
But for powerful centrifugal blower, above-mentioned radiating mode radiating efficiency is lower, is difficult to the cooling requirements meeting centrifugal blower.
Therefore, necessary the deficiency solving prior art is improved to prior art.
Model utility content:
In order to solve the problems of the technologies described above, the utility model provides a kind of centrifugal blower that can improve the dual-spiral sprue of radiating efficiency.
The utility model adopts following technological scheme: a kind of centrifugal blower of dual-spiral sprue, it comprises Blower Housing, be installed on the rotor in Blower Housing, be installed on the impeller of end on rotor and be installed on the cooling fan of rotor lower end, described Blower Housing is circumscribed with refrigerator, the refrigerant tubing flow into by the refrigeration agent in refrigerator in Blower Housing is connected with between described refrigerator and Blower Housing, the inwall of described Blower Housing is formed with the first helical flow path and the second helical flow path, described first helical flow path and the staggered spread configuration of the second helical flow path, described refrigeration agent is divided into two runners when flowing through Blower Housing along described first helical flow path and the second helical flow path and circulates.
The utility model has following beneficial effect: the utility model by arranging two helical flow paths on the inwall of Blower Housing, substantially reduce the distance of every bar helical flow path, reduce the inwall resistance of Blower Housing, be conducive to the flowing of refrigeration agent, improve the efficiency of refrigeration agent, and then improve the radiating efficiency of Blower Housing.
Accompanying drawing illustrates:
Fig. 1 is the schematic diagram of the centrifugal blower adopting air cooling way to dispel the heat in prior art.
Fig. 2 is the schematic diagram of the centrifugal blower of the utility model dual-spiral sprue.
Fig. 3 is that in Fig. 2, refrigeration agent flows to schematic diagram at refrigerant inlet and refrigerant outlet.
Wherein:
1-radiating fin; 2-Blower Housing; 3-rotor; 4-impeller; 5-cooling fan; 6-first helical flow path; 7-second helical flow path; A-refrigerant inlet; B-refrigerant outlet;
Embodiment:
Please refer to shown in Fig. 2 to Fig. 3, the centrifugal blower of the utility model dual-spiral sprue comprises Blower Housing 2, the rotor 3 be installed in Blower Housing 2, be installed on the impeller 4 of end on rotor 3 and be installed on the cooling fan 5 of rotor 3 lower end.
The inwall of wherein Blower Housing 1 is formed with two helical flow paths, and it is respectively the first helical flow path 6 and the second helical flow path 7, wherein the first helical flow path 6 and the staggered spread configuration of the second helical flow path 7.
The Blower Housing 1 of the utility model centrifugal blower is circumscribed with refrigerator, refrigeration agent in refrigerator flow in Blower Housing 1 by refrigerant tubing, wherein refrigeration agent is divided into two runners at refrigerant inlet A place along the first helical flow path 6 and the second helical flow path 7 circulates when inflow Blower Housing 1, finally discharges outside Blower Housing 2 after above-mentioned first helical flow path 6 in refrigerant outlet B place and the second helical flow path 7 merge.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art, can also make some improvement under the prerequisite not departing from the utility model principle, these improvement also should be considered as protection domain of the present utility model.
