The content of the invention
The purpose of this utility model is to provide the closed type centrifugal refrigerating that a kind of structure setting is reasonable and stability in use is good Motor rotary spray cooling structure.
The technical scheme for realizing the utility model purpose is a kind of closed type centrifugal refrigerating motor rotary spray cooling structure, Including support and end cap, rotor and stator are provided with the support, there is air gap between rotor and stator, the rotor is set In the underface of the stator, coolant connection terminal is fixed with the support, in the end cap be provided with it is described cold But the cooling passage that liquid connection terminal is connected, axial passage is provided with the bottom of the rotor, at the center of the rotor The air gap cooling duct being connected provided with bottom with axial passage, it is perpendicular that at least three parallel coolings are provided with the stator Hole, and cool down vertical core and be in logical with axial direction with least three parallel and bottoms on annulus, are further fixed on the rotor The coolant transmission channels that road is connected, the position of the coolant transmission channels is identical with the position for cooling down vertical core, described When rotor rotates, the tops of the coolant transmission channels and the bottom of cooling vertical core coincide, the axial passage with it is described Cooling duct is in same level.
Cavity is provided with the opening inwall of the cooling passage, baffle plate is provided with the cavity, in the gear Spring is fixed between the end wall of plate and the cavity, the outside of the baffle plate is in for the inclined low-end of inclined plane and inclined plane Coolant connection terminal side, the baffle plate are stretched into cooling passage in the presence of the spring.
The length that the baffle plate is stretched into cooling passage is the 1/4 of cooling passage diameter.
Installation journal stirrup is fixed with the support, mounting hole is fixed with the installation journal stirrup.
Its operation principle is summarized as follows:Extraneous coolant media is flowed into cold by the coolant connection terminal being arranged on end cap But liquid passage, the axial passage of rotor is entered back into.Coolant media is after the axial passage of rotor is entered, caused by rotor rotation Under centrifugal action:A part of coolant media enters cooling vertical core by coolant transmission channels and cools down motor stator;Another portion Coolant media is divided to enter the surface of air gap cooling stator inner circle and rotor outer circle by air gap cooling duct.So as to reach while cold But the purpose of motor stator and rotor.
The utility model has positive effect:Structure setting of the present utility model is reasonable, simple operation, can be effectively and fast Cooling of the completion of speed to motor stator and rotor, be advantageous to improve the stability in use and use reliability of electronics, applicability Strong and practicality is good.
Brief description of the drawings
In order that content of the present utility model is more likely to be clearly understood, below according to specific embodiment and combine attached Figure, is described in further detail to the utility model, wherein:
Fig. 1 is structural representation of the present utility model.
Embodiment
(embodiment 1)
Fig. 1 shows a kind of embodiment of the present utility model, and wherein Fig. 1 is structural representation of the present utility model Figure.
Fig. 1, a kind of closed type centrifugal refrigerating motor rotary spray cooling structure, including support 1 and end cap 2 are seen, described Rotor 3 and stator 4 are provided with support, there is air gap 5 between rotor and stator, the rotor be arranged on the stator just under Side, coolant connection terminal 6 is fixed with the support 1, is provided with and the coolant connection terminal phase in the end cap 2 The cooling passage 7 of connection, axial passage 8 is provided with the bottom of the rotor, and bottom and axle are provided with the center of the rotor The air gap cooling duct 9 being connected to passage, at least three parallel cooling vertical cores 10 are provided with the stator, and cooled down Vertical core is in on annulus, being further fixed on what at least three parallel and bottoms were connected with axial passage on the rotor Coolant transmission channels 11, the position of the coolant transmission channels is identical with the position for cooling down vertical core, is rotated in the rotor When, the top of the coolant transmission channels coincides with cooling down the bottom of vertical core, the axial passage and the cooling duct In same level.
Cavity 12 is provided with the opening inwall of the cooling passage, baffle plate 13 is provided with the cavity, in institute State and spring 14 is fixed between the end wall of baffle plate and the cavity, the outside of the baffle plate is low for the inclination of inclined plane and inclined plane End is in coolant connection terminal side, and the baffle plate is stretched into cooling passage in the presence of the spring.When in use, Inclined plane is provided with, bullet can be compressed when the fluid pressure of entrance is larger according to the fluid pressure of coolant connection terminal Spring is so that the length that baffle plate is stretched into cooling duct changes, so that the coolant tool from cooling passage outlet discharge There is stronger pressure, so as to ensure that the pressure of its liquid is more than the centrifugal force that rotor rotates, it is logical from axial direction to be advantageous to coolant Road enters.
The length that the baffle plate is stretched into cooling passage is the 1/4 of cooling passage diameter.
Installation journal stirrup 15 is fixed with the support, mounting hole 16 is fixed with the installation journal stirrup.
Its operation principle is summarized as follows:Extraneous coolant media is flowed into cold by the coolant connection terminal being arranged on end cap But liquid passage, the axial passage of rotor is entered back into.Coolant media is after the axial passage of rotor is entered, caused by rotor rotation Under centrifugal action:A part of coolant media enters cooling vertical core by coolant transmission channels and cools down motor stator;Another portion Coolant media is divided to enter the surface of air gap cooling stator inner circle and rotor outer circle by air gap cooling duct.So as to reach while cold But the purpose of motor stator and rotor.
Structure setting of the present utility model is reasonable, simple operation, effectively and can quickly finish to motor stator and rotor Cooling, be advantageous to improve the stability in use and use reliability of electronics, strong applicability and practicality is good.
Obviously, above-described embodiment of the present utility model is only intended to clearly illustrate the utility model example, and It is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, in described above On the basis of can also make other changes in different forms.There is no need and unable to give all embodiments It is exhaustive.And these belong to the obvious changes or variations that connotation of the present utility model is extended out and still fall within this practicality New protection domain.
