Abstract
The utility model discloses a water -cooling structure of car motor, including motor housing and left end lid, right -hand member lid, the last water course groove that is provided with axial, intercommunication both ends of motor housing, be provided with recesses that the position corresponds, two water course grooves of intercommunication on the medial surface of left end lid and right -hand member lid, be connected with the coupling on the recess of a set of symmetry of left end lid or right -hand member lid, the internal diameter of coupling does more than the twice in water course inslot footpath. Adopt two tunnel water routes and cool off, accelerate the water velocity simultaneously, improve the cooling effect, place car motor local overheat.
Description
Technical field
The utility model relates to a kind of water-cooling structure of electric motor of automobile.
Background technology
The structure of traditional former employing of electric motor of automobile water-cooling structure is the heat dissipation path of water channel groove from water inlet to delivery port of motor housing is a road, water channel groove makes circle distribution along the shape of rectangular ripple in frame shell wall, water circulation path is longer, water velocity is slow, and the flow velocity of water is one of heat-sinking capability important factor in order, therefore water circulation cooling effect is poor, electric machine temperature rise is high; The heat that electric machine iron core entirety produces in addition is uniform, but along with water channel groove and water inlet are apart from longer, the temperature of water is higher, cooling effect is deteriorated, form motor temperature rise everywhere uneven, particularly near the position of delivery port, cooling effect is the poorest, temperature rise is the highest, easily causes this position coil sections to burn out because temperature rise is too high.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of water-cooling structure of electric motor of automobile, adopts the cooling of two water routes and water channel tank circuit footpath is reduced one times, increasing water velocity, improving cooling effect.
The utility model solves the technical scheme that its technical problem adopts:
A kind of water-cooling structure of electric motor of automobile, include motor housing and left end cap, right end cap, described motor housing is provided with axial, to be communicated with two ends water channel groove, the medial surface of described left end cap and right end cap is provided with position corresponding, be communicated with the groove of two water channel grooves, the groove of one group of symmetry of described left end cap or right end cap is connected with pipe joint, and the internal diameter of described pipe joint is more than the twice of described water channel groove internal diameter.
As the improvement of technique scheme, the quantity of described water channel groove is the multiple of four.
As the further improvement of technique scheme, described water channel grooved ring is to being distributed on described motor housing.
Further, the groove of one group of symmetry of described left end cap or right end cap is respectively connected with two pipe joints.
Further, described left end cap and be provided with sealing gasket between right end cap and motor housing.
The beneficial effects of the utility model are: corresponding by being provided with position on the medial surface of left end cap and right end cap, the groove of the connection groove of two water channel grooves and one group of symmetry of left end cap or right end cap is connected with the structure of pipe joint, electric motor of automobile water-cooling structure is changed into two-way transmission, water channel groove internal diameter is less than the half of pipe joint, water velocity increases, greatly improve the cooling effect of electric motor of automobile, whole motor temperature is tended to balance, thus control electric machine temperature rise within allowed band, increase the load capacity of motor, prevent electric motor of automobile local temperature rise too high, improve the useful life of electric motor of automobile, and reconstruction structure is simple.The utility model is simple and practical, and implement simple, cost is low.

Embodiment
With reference to Fig. 1 ~ Fig. 4, a kind of water-cooling structure of electric motor of automobile, include motor housing 1 and left end cap 2, right end cap 3, described motor housing 1 is provided with axial, to be communicated with two ends water channel groove 101, the medial surface of described left end cap 2 and right end cap 3 is provided with position corresponding, be communicated with the groove 4 of two water channel grooves 101, the groove 4 of one group of symmetry of described left end cap 2 or right end cap 3 is connected with pipe joint 5, and the internal diameter of described pipe joint 5 is more than the twice of described water channel groove 101 internal diameter.Intake for left end cap 2, with reference to Fig. 4, water flows into from a groove 4 of left end cap 2, this groove 4 is communicated with 2 water channel grooves 101 and therefore forms two-way cooling water channel, current finally come together in another groove 4 be arranged symmetrically with the groove 4 of intaking and flow out behind the water route of rectangular ripple, thus formation two-way cooling water channel cools electric motor of automobile, improves cooling effect; In addition, the internal diameter of pipe joint 5 is more than the twice of described water channel groove 101 internal diameter, and increased water flow speed, improves cooling effect further.
In the present embodiment, preferably, the quantity of described water channel groove 101 is the multiple of four.Preferably, described water channel groove 101 hoop is distributed on described motor housing 1.Adopt said structure, ensure that the two-way cooling water channel formed is arranged symmetrically with, cooling effect is more balanced.
In the present embodiment, preferably, the groove 4 of one group of symmetry of described left end cap 2 or right end cap 3 is respectively connected with two pipe joints 5.Adopt said structure, two cooling water channels are intake and water outlet respectively, and discharge is larger, and cooling effect is better.
In the present embodiment, preferably, described left end cap 2 and be provided with sealing gasket 6 between right end cap 3 and motor housing 1, ensures sealing and anti-leakage.
The above, just better embodiment of the present utility model, but the utility model is not limited to above-described embodiment, as long as it reaches technique effect of the present utility model with any same or similar means, all should fall within protection range of the present utility model.
