Specific embodiment
The present invention is furture elucidated with reference to the accompanying drawing.
As shown in Figure 1, a kind of recirculated water cooling motor case, including base 1, the stator 3 being fixedly connected with the base 1,
Relative to the stator 3 rotation rotor 4 and be set to the end caps 5,6 of 1 left and right ends of base；
The base 1 includes inner cylinder 11, outer cylinder 12 and the cooling water being formed between the inner cylinder 11 and the outer cylinder 12
Channel 13,
The inner cylinder 11 is that indent is stepped, and the outer cylinder 12, which is arranged on the ladder of inner cylinder 11 to be formed with inner cylinder 11, to be cooled down
Aquaporin 13 is equipped with sealing element 9 between 12 both ends circumference of outer cylinder and outer cylinder 12；The inner cylinder 11 is located under 6 one side of right end end cap
Portion is equipped with inner end cap 7, and cavity 8 is formed between inner end cap 7 and right end end cap 6；Inner end cap 7 and inner cylinder 11 be an integral molding structure or
It is welded to connect with inner cylinder 11, cooling device 2 is equipped in cavity 8；
As shown in Fig. 2, the cooling device 2 include return pipe 24, phase-change energy storage plate 25, temperature detect switch (TDS) 26, refrigerator 27,
Fluid box 28 and inlet tube 29；Top, 11 bottom of inner cylinder of the cavity 8 offer discharge outlet, discharge outlet and return pipe 24
Connection, return pipe 24 are assemblied in 25 upper end of phase-change energy storage plate, and phase-change energy storage plate 25 is mounted on 28 upper end of fluid box, before fluid box 28
End is provided with temperature detect switch (TDS) 26 and refrigerator 27, and temperature detect switch (TDS) 26 is assemblied in 27 upside of refrigerator, the connection of 28 lower end of fluid box
There is inlet tube 29, inlet tube 29 connect and (do not mark in figure) with 11 water inlet of inner cylinder of 8 lower section of cavity, forms an Inlet and outlet water
Circulation.The design can recycle coolant liquid, reduce the wasting of resources, improve cooling effect.
Turbulence structure 10 is installed, the turbulence structure 10 includes running through institute along its length in the cooling-water duct 13
It states the shaft 101 of cooling-water duct 13, be set to the lateral wall of the outer cylinder 12 and the power with the shaft 101 transmission connection
Component, and it is installed on several flow-disturbing fins 102 of the shaft 101.Turbulence structure 10 can be designed so that cooling-water duct
Coolant liquid in 13 forms flow-disturbing, increases the heat exchange area between cooling water and motor, extends heat exchanger time, simultaneously
The cooling water of flow-disturbing has the power of flowing, can directly import in return pipe 24 by this power, then by refrigerator 27
Refrigeration is discharged into again in cooling-water duct 13.
The working principle of cooling device: a suitable temperature value is arranged in staff on temperature detect switch (TDS) 26, electronic
When machine is worked, staff opens the circulating pump inside fluid box 28, and coolant liquid is passed through 8 lower section of cavity by circulation pump work
11 water inlet of inner cylinder transport in cooling-water duct 13, the starting of turbulence structure 10 carries out flow-disturbing to coolant liquid, so that cooling
Liquid flows in entire cooling-water duct 13, since cooling-water duct 13 is located at 11 surface of inner cylinder, so entire machine can be surround
Shell main body is cooled down, and coolant liquid absorbs heat, and the coolant liquid after heating flows into return pipe 24 from the discharge outlet above cavity 8
In, then from return pipe 24 enter phase-change energy storage plate 25 inside built-in pipe in, 25 pairs of phase-change energy storage plate heat up after cooling
Liquid is cooled down for the first time, is come back in fluid box 28 by the coolant liquid to cool down for the first time, the temperature sensor in fluid box 28
Temperature measurement is carried out to coolant liquid and sends temperature signal to temperature detect switch (TDS) 26, the temperature of coolant liquid at this time is still very high,
Not up to temperature value set by temperature detect switch (TDS) 26 when, 26 automatic work of temperature detect switch (TDS) realizes temperature detect switch (TDS) 26 and refrigerator 27
Circuit connect, refrigerator 27 open work freeze, cool down again to coolant liquid, it is ensured that coolant liquid reaches suitable
Temperature improves coolant liquid to the cooling effect of motor case, which solves the existing motor with turbulence structure 10
Not the technical issues of coolant liquid in casing not can be carried out recycling, cause the wasting of resources.
The circuit of the cooling device 2 can may be that independent circuits and extraneous power supply connect with the circuit connection of motor
It connects.
The matching design of inner end cap 7 and right side end cap 5,6 not only makes motor case keep an overall structure, beautiful outline form
It sees, convenient for packaging, carries；And inner end cap 7 has obstructed the contact of internal structure of motor with cooling device 2, so that cooling device 2
With independent working space, on the one hand ensure that inside motor with the work independent of cooling device 2, do not interfere with each other, mention
High safety；On the other hand, replacement cooling device 2 easy to repair, as long as removal right end end cap 6 can repair or replace cooling
Device 2 avoids damaging internal structure of motor in maintenance process without influencing whether the structure inside motor.
Since temperature detect switch (TDS) 26 is located in cavity 8, so temperature detect switch (TDS) 26 wirelessly goes extraneous movement or solid
Fixed controller connection, wireless mode are bluetooth or Wifi connection.Controller is single-chip microcontroller or PLC controller etc..
Built-in pipe is installed, and built-in pipe is connected by hose with fluid box 28 inside the phase-change energy storage plate 25
It connects, the return pipe 24 passes through 25 upper end of phase-change energy storage plate and is connected with built-in pipe.
The temperature detect switch (TDS) 26 is connected by electric wire with refrigerator 27.
Fluid box 28 is arranged in the top of 6 section of stretching out of right end end cap, support construction of the right end end cap 6 as fluid box 28,
In order to guarantee the mounting stability of fluid box 28, at least three groups of spring 282,28 left side of fluid box are equipped in 28 two sides of fluid box
The natural length of spring 282 is greater than fluid box 28 at a distance from inner end cap 7, and the natural length of 28 right side spring 282 of fluid box is big
In fluid box 28 at a distance from right end end cap 6.When installation, the spring 282 of 28 left and right sides of fluid box is in confined state, can
To play the supporting role of left and right.Another mode is by the way that at least three horizontal support bars are arranged in the left side of fluid box 28
281, support rod 281 is equipped with mounting hole, and 7 surface of inner end cap is equipped with corresponding threaded hole, and support rod 281 passes through nut or spiral shell
