Abstract
The invention belongs to the technical field of motors and particularly relates to a motor case having advantages of uniform heat radiation and good heat radiating performance. The motor case comprises a shell, a water-cooled layer and end covers, wherein the housing is a hollow cylinder, uniformly distributed rifling in a direction consistent with the rotating direction of a motor are arranged on the periphery of the inner wall of the shell, uniformly distributed heat radiating fins are arranged on the periphery of the outer wall of the shell, the water-cooled layer covers the external portion of the shell, three uniformly distributed supporting and reinforcing ribs are arranged between the water-cooled layer and the shell, and the end covers are arranged at the two ends of the shell and are secured on the shell. The motor case can provide radial and axial heat radiation of the motor, better protect the motor and prolong the service life thereof.
Description
Technical field
The invention belongs to technical field of motors, be specifically related to a kind of motor housing even, thermal diffusivity is good that dispels the heat.
Background technology
Motor finds broad application as a kind of driven tool, a large amount of heats can be produced because motor runs up for a long time, the too high meeting of heat burns out motor, heat is too high is the main cause affecting motor useful life, radiating mode mainly air-cooled type and the water-cooled two kinds of current motor, but still there is the too high situation of the uneven amount of localized heat of heat radiation.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of motor housing even, thermal diffusivity is good that dispels the heat for above-mentioned situation, it can provide the radial and axial heat radiation of motor.
The technical solution adopted in the present invention is:
A kind of motor housing, comprise housing, water-cooled layer and end cap, described housing is hollow cylinder, inner walls side face is provided with the equally distributed rifling consistent with motor direction of rotation, housing exterior walls side face is provided with equally distributed fin, described water-cooled layer is coated on outside, and be provided with 3 equally distributed supporting rib stiffeners between water-cooled layer and housing, described end cap is arranged on housing two ends and is fixed on housing.
The initiating terminal of the every bar rifling of described inner walls and end are with point-blank, and rifling is only around inner walls one week, and described housing exterior walls fin quantity is 21.
Described supporting rib stiffener is provided with the through hole being convenient to the circulation of water-cooled liquid, and the end face of supporting rib stiffener is provided with the screwed hole of fixing end cap.
Described end cap is provided with ventilating opening, and the coated right side of ventilating opening is dust-proof.
Be provided with water inlet other end top bottom described water-cooled layer one end and be provided with delivery port.
The invention has the beneficial effects as follows: adopt such scheme, water-cooled is combined with air cooling, the radial and axial heat radiation of motor can be provided, loose 1 backing of housing exterior walls and the water-cooled layer of outer wrap provide the heat radiation of motor radial direction, water-cooled liquid enters from bottom water inlet and is slowly full of whole water-cooled layer and flows out from top delivery port, housing contacts with water-cooled liquid and improves contact area greatly in conjunction with the fin of housing exterior walls in this course increases heat dissipation capacity, and water circulation plays Homogeneouslly-radiating effect; Inner walls has the rifling consistent with motor direction of rotation, motor is meeting agitation air when High Rotation Speed, make air by flowing along inner walls rifling in the ventilating opening suction casing of end cap, there is provided the axis of motor to dispel the heat, the two combination makes the useful life that motor radiating is even, thermal diffusivity improves well motor.
Accompanying drawing explanation
Fig. 1 is perspective view of the present invention;
Fig. 2 is left view of the present invention;
Fig. 3 is cross-sectional view of the present invention;
Fig. 4 is longitudinal section of the present invention.
In figure: 1 is water-cooled layer, 2 is housing, and 3 is screwed hole, and 4 is supporting rib stiffener, and 5 is rifling, and 6 is end cap, and 7 is dust cover, and 8 is air vent hole, and 9 is fin, and 10 is delivery port, and 11 is through hole, and 12 is water inlet.
Embodiment
See motor housing shown in Fig. 1-4, comprise housing 2, water-cooled layer 1, end cap 6, housing 2 is hollow cylinder, housing 2 inwall side face is provided with the equally distributed rifling 5 consistent with motor direction of rotation, the initiating terminal of every bar rifling 5 and end are with point-blank, and rifling 5 is only around housing 2 inwall one week, housing 2 outer wall side face is provided with equally distributed fin 9, it is outside that water-cooled layer 1 is coated on housing 2, 3 equally distributed supporting rib stiffeners 4 are provided with between water-cooled layer 1 and housing 2, supporting rib stiffener 4 is provided with the through hole 11 being convenient to the circulation of water-cooled liquid, be provided with water inlet 12 other end top bottom water-cooled layer 1 one end and be provided with delivery port 10, end face is also provided with the screwed hole 3 of fixing end cap 6, end cap 6 is fixed by screws on housing 2.The water circulation that bottom during work, water inlet 12 and top delivery port 10 are formed can absorb uniformly takes away a large amount of heats, water-cooled liquid directly contacts with housing 2 and fin 9 turn increases contact area and substantially increases radiating efficiency, motor rotates and makes drive air agitation, motor end can form negative pressuren zone, air enters in housing 2 by the air vent hole 8 on end cap 6, housing 2 inwall has rifling 5, air can flow out along rifling 5 from motor end parts to motor front end and from the air vent hole of front end housing, take away heat simultaneously, dust cover 7 coated on air vent hole 8 can prevent dust from entering in electric machine casing 2, the initiating terminal of rifling 5 can end all on the same line and only around housing 2 inwall one week, be conducive to air flowing like this, air turbulence can not be formed, be conducive to heat radiation.Water-cooled combines with air cooling and makes that motor is radial and axial all to be obtained Homogeneouslly-radiating thus protect motor to extend its useful life.
The present invention is not limited to described embodiment, and those skilled in the art, not departing from spirit of the present invention namely openly in scope, still can do some and revise or change, therefore the scope that the scope of the present invention limits with claims is as the criterion.
