Abstract
The utility model relates to a motor heat dissipation end cover which comprises a cover body formed by an inner ring and an outer ring, wherein the outer ring is distributed with radiation ribs which are provided with ventilation channels; a cooling air circulating bin is arranged on the outer ring close to the inner ring; the radiation ribs are fixedly connected with the cooling air circulating bin; the ventilation channels of the radiation ribs are communicated with the cooling air circulating bin; air inlets of the ventilation channels of the radiation ribs are distributed near the outer ring; and the outer ends of the radiation ribs are provided with air outlets. The motor heat dissipation end cover realizes double heat dissipation of the radiation ribs, and remarkably improves the heat dissipation effect.
Description
Technical field
The utility model relates to a kind of electric motor end cap, relates in particular to a kind of electric motor end cap that has radiating ribs.
Background technology
Motor radiating is a big problem of machine field all the time.Along with the development of electric machine industry, power of motor do bigger and bigger, the motor radiating problem is also more and more outstanding.The motor big for power, that volume is little, the motor bearings a great problem especially that dispels the heat.
Disclose a kind of motor radiating end cap Chinese patent ZL200620118624.4 number, be evenly distributed with some radiating ribs on this end cap lid, but its radiating ribs being solid, only is to increase cooling surface area, and radiating rate is still slower, and it is desirable that radiating effect is still owed.
The utility model content
The purpose of this utility model is to provide a kind of radiating effect better to have the electric motor end cap of radiating ribs.
The technical solution of the utility model is: it comprises the lid that is made of interior ring and outer shroud, be distributed with radiating ribs on the described outer shroud, described radiating ribs is provided with vent passages, be provided with cooling air circulation storehouse near interior ring place on the outer shroud, radiating ribs is fixedlyed connected with the cool cycles storehouse, in the vent passages of radiating ribs and the cooling air circulation storehouse; The air inlet of the vent passages of radiating ribs is distributed near the outer shroud; The outer end of radiating ribs is provided with air outlet.
Radiating ribs can be welding, rivets or is connected by nut with the fixedly connected mode in cool cycles storehouse.
The utility model both can be by the outwards heat radiation of radiating ribs surface, and be provided with vent passages and air outlet in it, cooling air can pass through vent passages, and discharge from air outlet, thereby reach the purpose of radiating ribs internal heat dissipating, so dispel the heat simultaneously, improved radiating effect effectively by the radiating ribs surfaces externally and internally.
Description of drawings
Fig. 1 is the structural representation (vertical view) of the utility model embodiment;
Fig. 2 looks (local for analysing and observe) figure for Side embodiment illustrated in fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
With reference to accompanying drawing 1,2, present embodiment comprises the lid that is made of interior ring 5 and outer shroud 6, be distributed with radiating ribs 2 on the described outer shroud 6, described radiating ribs 2 is provided with vent passages 3, be provided with cooling air circulation storehouse 7 near interior ring 5 places on the outer shroud 6, radiating ribs 2 is fixedlyed connected with cool cycles storehouse 7, and the vent passages 3 of radiating ribs 3 is communicated with cooling air circulation storehouse 7; The air inlet 4 of the vent passages 3 of radiating ribs 2 is distributed near the outer shroud 6; The outer end of radiating ribs 2 is provided with air outlet 1.
Radiating ribs 2 is fixedlyed connected mode with cool cycles storehouse 7, can be welding, and nut connects or riveted joint.
Motor is in running, and the heat that end cap and bearing produce is delivered on the radiating ribs 2 by end cap lid and bearing, is distributed to the outside from radiating ribs 2 surfaces again; Simultaneously, the cold wind that comes out from cooler enters cool cycles storehouse 7 from air inlet 4, enters vent passages 3 in the radiating ribs 2 by cool cycles storehouse 7 again, then discharges from air outlet 1, can take away a part of heat again, thereby realize radiating ribs inside and outside dual heat radiation cooling.
Claims (4)
