Liquid cooled motor assembly and cover thereof

Abstract

A liquid cooled motor assembly and a cover thereof The cover of the liquid cooled motor assembly has an outer cylinder, an inner cylinder, a channel and multiple fins. The inner cylinder is mounted in and connected securely with the outer cylinder. The channel is zigzag and is formed between the inner cylinder and the outer cylinder. The fins are mounted securely on an outer surface of the inner cylinder. With the fins mounted on the outer surface of the inner cylinder, water can dissipate heat from the fins quickly and a dissipating efficiency is enhanced.

1 . A cover of a liquid cooled motor assembly, the cover comprising:
 an outer cylinder;   an inner cylinder, mounted inside the outer cylinder and having
 two opposite ends; 
 a length; 
 an outer surface; and 
 multiple elongated connecting sections formed on and protruding from the outer surface of the inner cylinder at intervals, connected securely with the outer cylinder, each connecting section having
 a length the same as that of the inner cylinder; 
 an end; and 
 
 multiple breaches respectively formed at the ends of the connecting sections, wherein the adjacent two of the breaches are respectively located at the ends of the inner cylinder; 
   a zigzag channel formed between the outer cylinder and the inner cylinder; and   multiple fins mounted securely on the outer surface of the inner cylinder except at the connecting sections.   
     
     
         2 . The cover of a liquid cooled motor assembly as claimed in  claim 1 , wherein each connecting section is linear and extends along a line parallel to an axis of the inner cylinder. 
     
     
         3 . The cover of a liquid cooled motor assembly as claimed in  claim 2 , wherein at least two fins are located at each position between adjacent two connecting sections; and each fin is linear and extends along a line parallel to the axis of the inner cylinder. 
     
     
         4 . The cover of a liquid cooled motor assembly as claimed in  claim 3 , wherein
 the outer cylinder has
 an inner surface; 
 an inlet radially formed in the outer cylinder and communicating with the channel; 
 an outlet radially formed in the outer cylinder and communicating with the channel; and 
 a block section formed on and protruding from the inner surface of the outer cylinder, being beam-shaped, extending along a line parallel to the axis of the inner cylinder, located between the inlet and the outlet and connected securely with the outer surface of the inner cylinder except at the connecting sections. 
   
     
     
         5 . The cover of a liquid cooled motor assembly as claimed in  claim 4 , wherein the outer cylinder has a hanging hole radially formed in the outer cylinder and located between the inlet and the outlet. 
     
     
         6 . A liquid cooled motor assembly comprising:
 a cover having
 a first end; 
 a second end opposite to the first end of the cover; 
 an outer cylinder; 
 an inner cylinder, mounted inside the outer cylinder and having
 an axial space; 
 two opposite ends; 
 a length; 
 an outer surface; and 
 multiple elongated connecting sections formed on and protruding from the outer surface of the inner cylinder, connected securely with the outer cylinder, each connecting section having
 a length the same as that of the inner cylinder; 
 an end; and 
 a breach formed at the end of the connecting section, wherein the adjacent two of the breaches are respectively located at the ends of the inner cylinder; 
 
 
 a zigzag channel formed between the outer cylinder and the inner cylinder; and 
 multiple fins mounted securely on the outer surface of the inner cylinder except at the connecting sections; 
   a motor device mounted inside the axial space of the inner cylinder;   a first cap mounted securely on the first end of the cover;   a second cap mounted securely on the second end of the cover, wherein the first cap and the second cap seal the channel and the axial space of the inner cylinder; and   a washer kit connected with the cover.   
     
     
         7 . The liquid cooled motor assembly as claimed in  claim 6 , wherein each connecting section is linear and extends along a line parallel to an axis of the inner cylinder. 
     
     
         8 . The liquid cooled motor assembly as claimed in  claim 7 , wherein at least two fins are located at each position between adjacent two connecting sections; and each fin is linear and extends along a line parallel to the axis of the inner cylinder. 
     
     
         9 . The liquid cooled motor assembly as claimed in  claim 8 , wherein
 the outer cylinder has
 an inner surface; 
 an inlet radially formed in the outer cylinder and communicating with the channel; 
 an outlet radially formed in the outer cylinder and communicating with the channel; and 
 a block section formed on and protruding from the inner surface of the outer cylinder, being beam-shaped, extending along a line parallel to the axis of the inner cylinder, located between the inlet and the outlet and connected securely with the outer surface of the inner cylinder except at the connecting sections. 
   
     
     
         10 . The liquid cooled motor assembly as claimed in  claim 9 , wherein the outer cylinder has a hanging hole radially formed in the outer cylinder and located between the inlet and the outlet.
