Abstract
The utility model, which belongs to the motor field, relates to a low-noise motor cooling device. A louver board (2) is installed outside a base (3) approaching a shaft extending end of a motor (1); a radial ventilating duct is arranged in the base (3); a screw (5) passes through an installing hole of a fan cover (7) and is engaged with an internal thread of a hole of an end cover (4) of a non-shaft extending end of the motor (1); and a ventilation hole is arranged at the end cover (4) of the motor (1). The provided low-noise motor cooling device has the characteristics of low noise, good heat dissipation, simple structure and convenient installation and the like.
Description
Technical field
The utility model relates to machine field, especially a kind of low noise motor heat abstractor.
Background technology
1. existing variable-frequency motor heat abstractor mostly adopts independently centrifugal fan heat radiation.Employing is equipped with centrifugal blower outside the support of motor, utilize centrifugal blower to blow into wind, and the heat dissipation channel through in motor, go out from the rear end cap louvre, and the heat of motor is taken away.
The shortcoming of existing variable-frequency motor heat abstractor:
1. air quantity is little;
2. noise is larger.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, adopt absorption radiator structure, any one party in the non-shaft extension of motor is installed the individual motor with centrifugal impeller, on the support on the motor respective direction or end cap, process ventilation hole and protected, utilizing the individual motor energising to drive centrifugal impeller rotates, make to carry out exchange heat inside and outside motor, thus the low noise motor heat abstractor that motor is dispelled the heat.
The purpose of this utility model adopts technical scheme, comprise motor, individual motor, the main shaft of aforesaid individual motor is equipped with centrifugal impeller, centrifugal impeller is covered with the fan housing of air-out cylindrical void radially, between individual motor and fan housing, with bolt, connect, near outside the support of motor-shaft extending end, louver board is being housed, support has radial ducts, screw passes the ending cover hole internal thread engagement of fan housing installing hole and motor non-shaft stretching end, and the end cap of aforesaid motor has ventilation hole.
The utility model is by means of individual motor energising, to drive centrifugal impeller to rotate, and the motor cooling air is advanced from louver board, through the radial ducts of support and end cap, from fan housing radially the air-out cylindrical void go out, motor is dispelled the heat.
The utlity model has that noise is little, good heat dissipation, the characteristics such as simple in structure, easy for installation.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, further illustrate the utility model.
Fig. 1 is the utility model structural representation.
In figure: 1-motor, 2-louver board, 3-support, 4-end cap, 5-screw, 6-centrifugal impeller, 7-fan housing, 8-individual motor.
Embodiment
As Fig. 1, the main shaft that comprises motor 1, individual motor 8, aforesaid individual motor 8 is equipped with centrifugal impeller 6, centrifugal impeller 6 is covered with the fan housing 7 of air-out cylindrical void radially, between individual motor 8 and fan housing 7, with bolt, be connected, the outer louver board 2 that is equipped with of its support by motor 1 shaft extension end 3, in support 3, radial ducts is arranged, screw 5 passes the end cap 4 hole internal thread engagements of fan housing 7 installing holes and motor 1 non-shaft stretching end, and the end cap 4 of aforesaid motor 1 has ventilation hole.
With the 400kW motor of low noise heat abstractor, the actual measurement noise is 84dB (A), and is 110dB (A) with the noise of centrifugal fan independently.
Claims (1)
1. low noise motor heat abstractor, comprise motor (1), individual motor (8), the main shaft of aforesaid individual motor (8) is equipped with centrifugal impeller (6), centrifugal impeller (6) is covered with the fan housing of air-out cylindrical void (7) radially, between individual motor (8) and fan housing (7), with bolt, be connected, it is characterized in that near the outer louver board (2) that is equipped with of the support (3) of motor (1) shaft extension end, support has radial ducts in (3), screw (5) passes end cap (4) the hole internal thread engagement of fan housing (7) installing hole and motor (1) non-shaft stretching end, the end cap (4) of aforesaid motor (1) has ventilation hole.
