Beneficial effect is: a kind of cooling device of the present invention, and by being set with the high inner core of heat transfer efficiency in motor outer rim, the heat that motor is distributed conducts to coolant fast, effectively reduces the temperature of motor, extends the useful life of motor; Cooling device is sleeved on outside motor and uses bolt to connect, easy for installation; The shell of cooling device not only avoid motor and is damaged by colliding, and noise when reducing electric machine rotation, improves operational environment.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail:
Fig. 1 is the schematic diagram of a kind of cooling device in the present invention.
Embodiment
Direction shown in arrow is coolant flow direction.
A kind of cooling device as shown in Figure 1, this device is mainly used in electric motor temperature reduction.Cooling device comprises the motor 1 that main shaft is vertically arranged and the cooling device be fixedly arranged on motor 1, and cooling device comprises the shell 2 of tubular, the inner core 3 be set in shell 2, the flow deflector 21 be fixedly arranged on shell 2 inwall, is fixedly arranged on the entrance 4 on shell 2 and exports 5; Tubular inner core 3 is sleeved on outside motor 1, shell 2 is sealed by sealing device with the two ends of inner core 3, flow deflector 21 is fixedly arranged on the inwall of shell 2 in the shape of a spiral, is filled with coolant in the cavity between shell 2 and inner core 3, and inner core 3 uses the good aluminum alloy materials of heat conductivity to make.The heat conduction that motor 1 running produces, on inner core 3, makes the temperature of inner core 3 raise; From the coolant that entrance 4 inputs, under the effect of flow deflector 21, flowing of rising in the shape of a spiral, by outlet 5 is flowed out after doing heat exchange in flow process with inner core 3; Coolant helical form rises, and can improve the heat exchanger effectiveness of coolant and inner core 3.Accommodation coolant is not only in the effect of shell 2, and motor 1 can also be avoided to be collided and to damage; If motor 1 is mounted in outdoor, motor 1 can also be avoided to expose to the sun and rain, extend the useful life of motor 1.
Described sealing device comprises the end cap 7 of the annular being arranged at shell 2 two ends, and the two ends of inner core 3 are provided with the flanging 31 of the annular abutted against with the end of shell 2, and the end of flanging 31 with housing 2 compresses and use bolted by end cap 7.
In order to prevent coolant from leaking out between shell 2 and inner core 3, between described shell 2 and flanging 31, be folded with pad, pad uses nitrile rubber to make.
Described inner core 3 is provided with the fin 32 identical with flow deflector 21 hand of spiral in shell 2.Fin 32 makes inner core 3 increase with the contact area of coolant, and add the heat conduction efficiency between fin 32 and coolant, the heat that motor 1 is given out can be passed to coolant faster; Fin 32 also plays the effect of water conservancy diversion simultaneously, and coolant is contacted with inner core 3 more fully.
