Abstract
The utility model relates to a hull of an electric machine with flow guiding radiating paths. The utility model has good radiating effect, can extend the service life of an electric machine, and can improve the use performance of the electric machine. The utility model is composed of a stator hull and a fan housing. The periphery of the stator hull is provided with a plurality of axial radiating ribs and grooves which are uniform distributed at intervals. The fan housing which is arranged outside a fan and is positioned on the side end of the stator hull is tightly sheathed on the axial radiating ribs of the stator hull. Flow guiding radiating paths for guide radiating air current are formed between the fan housing and the axial grooves on the stator hull.
Description
The utility model belongs to motor component, particularly a kind of electric machine casing with diversion heat-dispersion path.
As shown in Figure 1 and Figure 2, the electric machine casing of commonly using is made up of stator case and fan guard, and stator case is cast by cast iron, and its periphery is laid with axial cooling fin and groove; Cover in the outer fan guard of fan and be positioned at the side of stator case, and and stator case on axial cooling fin between have breach.The motor that adopts this electric machine casing in the running, the radiating airflow that fan produced on it on the stator case axial cooling fin and the breach between the fan guard directly to around dissipation, do not blow to axial notch on the stator case, thereby can't reach the cooling stator case effectively to improve the radiating condition of motor, have a strong impact on the useful life of motor and very easily cause the damage of motor internal parts.
The electric machine casing that the purpose of this utility model provides a kind of good heat dissipation effect, can prolong motor useful life, serviceability is good with diversion heat-dispersion path.
The utility model is made up of stator case and fan guard, and the stator case periphery is provided with a plurality of axial cooling fin and grooves uniformly at intervals; Cover in the outer and fan guard that is positioned at the stator case side of fan closely cover cover on outside the axial cooling fin of stator case, and between the axial notch on fan guard and the stator case, constitute the diversion heat-dispersion path of guiding radiating airflow.
Because the utility model is made up of stator case and fan guard, the stator case periphery is provided with a plurality of axial cooling fin and grooves uniformly at intervals; Cover in the outer and fan guard that is positioned at the stator case side of fan closely cover cover on outside the axial cooling fin of stator case, and between the axial notch on fan guard and the stator case, constitute the diversion heat-dispersion path of guiding radiating airflow.
When motor rotation, the radiating airflow that fan produced on it flows through the stator case surface along the diversion heat-dispersion path between axial notch on the stator case and the fan guard, improve the radiating effect of axial cooling fin on the stator case, cool off stator case effectively with the radiating condition that improves motor and the serviceability of motor, prolong the useful life of motor, thereby reach the purpose of this utility model.
Fig. 1, for adopting the electric machine structure schematic isometric of the electric machine casing commonly use.
Fig. 2, the radiating airflow flow schematic diagram that produces for the fan of the motor that adopts the electric machine casing commonly use.
Fig. 3, for having electric machine structure schematic isometric of the present utility model.
Fig. 4, for having motor decomposition texture schematic isometric of the present utility model.
Fig. 5, the radiating airflow flow schematic diagram that produces for fan with motor of the present utility model.
Below in conjunction with accompanying drawing the utility model is further elaborated.
As shown in Figure 3, Figure 4, the utility model is made up of stator case 1 and fan guard 2, and stator case 1 is formed by the die casting of aluminium alloy one, and its periphery is provided with a plurality of axial cooling fin 11 and grooves 12 uniformly at intervals; Fan guard 2 is positioned at the side of stator case 1, cover in be installed on the rotor axis of electric 3 fan 4 outer and closely cover cover on the stator case 1 axially outside the cooling fin 11, and between the axial notch 12 on fan guard 2 and the stator case 1, constitute the diversion heat-dispersion path 5 of guiding radiating airflow; Fan guard 2 is fixedly mounted on the stator case 1 with screw 6 and packing ring 7.
During motor rotation, as shown in Figure 5, the fan 4 that is installed on the armature spindle 3 produces the radiating airflow of turn, and this radiating airflow flows through stator case 1 surface along the diversion heat-dispersion path 5 between axial notch 12 on the stator case 1 and the fan guard 2, improves the radiating effect of axial cooling fin 11 on the stator case 1.
Claims (2)
1, a kind of electric machine casing with diversion heat-dispersion path, it is made up of stator case and fan guard, and the stator case periphery is provided with a plurality of axial cooling fin and grooves uniformly at intervals; Cover in the outer fan guard of fan and be positioned at the side of stator case, it is characterized in that described fan guard closely cover cover on outside the axial cooling fin of stator case, and between the axial notch on fan guard and the stator case, constitute the diversion heat-dispersion path of guiding radiating airflow.
