The present invention operation principle and the course of work be:
The cooling device motor easy to disassemble of the present invention, the installation space of cooling device is reserved in housing exterior walls, cooling
The water-cooled layer of device is coated on the outer wall of shell, and water-cooled layer is close to the outer wall of shell, and water-cooled layer is closed annular.It first will be cold
But device is installed to the periphery of motor, and the water-cooled layer and water inlet pipe material used in the present invention are flexible material, can be fitted
Answering property is adjusted, and the first water inlet pipe side opposite with the second water inlet pipe is provided with regulating device, for adjusting the interior of water-cooled layer
The size of diameter, to adapt to different size of motor, the first water inlet pipe outer wall is connected with sliding block, outer wall of the sliding block in the first water inlet pipe
It can move up and down, the sliding slot moved convenient for sliding block is offered in the outer wall of the first water inlet pipe, according to the size of real electrical machinery, adjust
After the relative altitude of good sliding block, applying external force in the first armlet and the second armlet makes limited block be leaned on to centre spring-compressed
Closely, then limited block is made to be put into limiting slot, removes external force, limited block is made to abut against limit under the action of the restoring force of spring
In the slot of position, meanwhile, external force is applied to hook, so that elastic band is extended, then hook is suspended on corresponding link, has been assisted
The housing exterior walls of motor are abutted against at water-cooled layer；When needing to dismantle cooling device, limited block is made to be detached from limiting slot first, with
And hook is detached from link, that is, completes water-cooled layer to the holding of motor, the dismounting of cooling device then can be realized.Water-cooled layer
Upper end is connected with water inlet pipe, and lower end is connected with water outlet, and the lower end bifurcated of water inlet pipe forms the first water inlet pipe and the second water inlet pipe,
The water-cooled layer of annular is divided into left and right two parts by the outer wall of the first water inlet pipe and the second water inlet pipe, is allowed the water to through the first water inlet
Pipe enters the both sides of water-cooled layer with the second water inlet pipe simultaneously, and flow is entered after the lower end of water-cooled layer is converged by water outlet
In connecting tube, then by the effect of water pump by the water with heat is pumped into water storage box and is recycled, in water-cooled layer
The inner wall in the interior close center of circle is provided with the first flow deflector, and the inner wall far from the center of circle is provided with the second flow deflector in water-cooled layer, the
The inner wall of one end and water-cooled layer of one flow deflector and the second flow deflector is connected with each other, and the first flow deflector is another with the second flow deflector
End is hanging, and the free end of the first flow deflector and the second flow deflector is shifted to install along water (flow) direction.When the wider width of motor, such as
Then the width that fruit increases water-cooled layer is radiated although can also realize the covering to motor by way of water cooling, this
Sample heat dissipation effect is poor, and water absorbs heat water temperature in water-cooled layer and increases rapidly, makes the temperature and electric machine casing of the water in water-cooled layer
Temperature difference is small, and radiating efficiency is low, just needs to add a mutually independent water-cooled layer at this time and radiate, makes phase between water-cooled layer
Mutual heat dissipation does not influence each other, and improves radiating efficiency, is coordinated by the way that swallow-tail form is arranged in the side wall of water-cooled layer, you can realize water cooling
Connection between layer, meanwhile, the water cycle in water-cooled layer is independent of each other independently of each other.
Beneficial effects of the present invention are as follows：
1, cooling device of the invention can realize convenient and efficient dismounting, and flow deflector is provided in water-cooled layer, increase flow
With the contact area of water-cooled layer inner wall, slow down the flowing velocity of flow, improves flow in the flow time of water-cooled layer, fully take away
The heat of electric machine casing, to achieve the effect that reduce the temperature of motor；Flow by the first water inlet pipe and the second water inlet pipe into
Enter into water-cooled layer, the water for entering water-cooled layer all keeps lower temperature, makes the good heat dissipation effect of water-cooled layer both sides, water is avoided to exist
Annular cycle is carried out in water-cooled layer, is increased with the distance that flows through of flow, cooling effect reduces.
2, coordinated by water pump and water storage box, cooling water is made to recycle, reduce water resource waste.
3, the first flow deflector and the second flow deflector of water-cooled layer inner wall setting, the first flow deflector and the second flow deflector are along flow
Direction tilts, arc-shaped recess, and the free end of the first flow deflector and the second flow deflector is arranged along water (flow) direction mistake, water cooling
Water in layer plays the role of stirring when flowing through the channel formed between the first flow deflector and the second flow deflector, make high-temperature water with it is low
Warm water is mixed, and avoids high-temperature water from carrying out heat transfer only by way of diffusion with water at low temperature, whole water is taken away outside shell
The thermal efficiency of wall is low.
4, by regulating device, the inner diameter size of water-cooled layer is adjusted, to adapt to different size of electric machine casing, passes through limit
Block is matched with fiber slot, and hook is matched with link, ensure that water-cooled layer is close to the outer wall of electric machine casing, to reach more efficient
Transmit the effect of heat.
5, by the way that dovetail groove is arranged in the side of water-cooled layer, in the side of another water-cooled layer, setting cooperates with dovetail groove
Dovetails, make to be overlapped by way of dovetail cooperation between book cooling layer, realize that water-cooled layer keeps an entirety, and
Water in water-cooled layer keeps mutual indepedent.
