The heat dissipation ditch of recess is provided with several ventilation blocks in the heat dissipation ditch, and the side of the bound edge offers air inlet, institute
State every offered on platform several connection heat dissipation ditches and axis hole interface channel.
The technical effect of this electric motor end cap are as follows: relative to traditional electric motor end cap, offered on the end casing of this motor into
The interface channel in air port, heat dissipation ditch and connection heat dissipation ditch and axis hole, at work, this end casing can be with radiator fan one for motor
It is used with collocation, the air-flow that radiator fan work drives can pass the gas through air inlet and enter heat dissipation ditch inside motor
In, the ventilation block being set in heat dissipation ditch can help to improve the transmitting contact area of air-flow, be then discharged by interface channel.
In a kind of above-mentioned electric motor end cap, the ventilation block circumferential direction Rotating with Uniform described in several is distributed in radiating groove,
And the both ends of each ventilation block each extend over and are fixed on bound edge, every on platform, the top of the ventilation block has been offered in circle
The ventilation gap of arcuation.The setting of ventilation block can help to promote residence time of the air-flow in end casing, biography as much as possible
Heat is passed, radiating efficiency is improved.
In a kind of above-mentioned electric motor end cap, described every offering air hole on platform, the air hole is equidistantly equal
It is even to be distributed in every on the top surface of platform.It helps to carry out heat exchange inside motor.
In a kind of above-mentioned electric motor end cap, the quantity of the interface channel is 2, and interface channel described in two is symmetrical
It is distributed in end casing two sides.
In a kind of above-mentioned electric motor end cap, the setting of interface channel opposite tilt described in two.The connection being obliquely installed
Channel can help for the air-flow in the ditch that radiates preferably to be introduced into axis hole.
Compared with prior art, air inlet, heat dissipation ditch and connection heat dissipation ditch are offered on the end casing of this electric motor end cap
With the interface channel of axis hole, air circulation can be realized to motor inside by a series of radiator structure, good with thermal diffusivity,
Structurally reasonable advantage.
