Motor device with heat dissipating capability

Abstract

A motor device includes a motor body and a set of heat-conducting pipes. The motor body includes a motor casing that defines a chamber, a stator that is disposed in the chamber, and a rotor that is rotatably disposed in the chamber. Each of the heat-conducting pipes has a heat-absorbing end that extends into the motor body, and a heat-dissipating end that is opposite to the heat-absorbing end and that extends outwardly of the motor body.

1 . A motor device comprising:
 a motor body including a motor casing that defines a chamber, a stator that is disposed in said chamber, and a rotor that is rotatably disposed in said chamber; and   a set of heat-conducting pipes, each having a heat-absorbing end that extends into said motor body, and a heat-dissipating end that is opposite to said heat-absorbing end and that extends outwardly of said motor body.   
   
   
       2 . The motor device as claimed in  claim 1 , further comprising a plurality of heat-dissipating fins disposed on a surface of said motor casing, said heat-dissipating ends of said heat-conducting pipes extending between said surface of said motor casing and said heat-dissipating fins. 
   
   
       3 . The motor device as claimed in  claim 1 , further comprising a fan unit disposed on a surface of said motor casing, said heat-dissipating ends of said heat-conducting pipes extending between said surface of said motor casing and said fan unit. 
   
   
       4 . The motor device as claimed in  claim 3 , wherein said fan unit is coupled co-rotatably to said rotor. 
   
   
       5 . The motor device as claimed in  claim 1 , further comprising a cooling unit disposed on a surface of said motor casing, said cooling unit being formed with a coolant channel, and a coolant inlet and a coolant outlet that are in fluid communication with said coolant channel, said heat-dissipating ends of said heat-conducting pipes extending into said cooling unit. 
   
   
       6 . The motor device as claimed in  claim 5 , wherein said cooling unit includes:
 a base part having one side formed with a groove that serves as said coolant channel, said base part being formed with said coolant inlet and said coolant outlet, said heat-dissipating ends of said heat-conducting pipes extending into said base part; and   a cover part that covers removably said one side of said base part.   
   
   
       7 . The motor device as claimed in  claim 5 , wherein said coolant channel is spiral. 
   
   
       8 . The motor device as claimed in  claim 1 , wherein said heat-absorbing ends of said heat-conducting pipes extend into said motor casing. 
   
   
       9 . The motor device as claimed in  claim 1 , wherein said heat-absorbing ends of said heat-conducting pipes extend between said stator and said motor casing. 
   
   
       10 . The motor device as claimed in  claim 1 , wherein said heat-absorbing ends of said heat-conducting pipes extend into said stator.
