Liquid circulation system and liquid cooling system therewith

Abstract

A pump equipped with an impeller having a plurality of vanes is installed through a packing at an opening section formed on a wall surface of one of components in a liquid circulation passage, such as a radiator so that the impeller of the pump section may be disposed herein. Inside the component, there is provided a partition plate formed with a hole at such a position as to face the center of the impeller. A port is provided between a wall surface having the opening section and the partition plate. By the rotation of the impeller, a liquid flow is produced toward the port from the inside of the compartment through the hole.

1 . A liquid circulation system which permits liquid to pass through a component thereof, comprising: 
 an impeller having a plurality of vanes;    a wall of the component on which the impeller is mounted and in which an opening section is formed so as to permit the vanes to be disposed;    a partition section having a hole at such a position as to face a rotating shaft of the impeller; and    a port formed by the wall and the partition section, wherein    the liquid passing through the component flows into the port through the hole by the rotation of the impeller.    
   
   
       2 . The liquid circulation system according to  claim 1 , comprising: 
 a bottom wall for supporting the rotating shaft of the impeller; and    electromagnets mounted on the opposite side to the impeller on the bottom wall, wherein    the impeller is rotated by the electromagnets and permanent magnets included in the impeller.    
   
   
       3 . The liquid circulation system according to  claim 2 , wherein the bottom wall includes a liquid sealing member on the same side as the impeller.  
   
   
       4 . A liquid circulation system which permits liquid to pass through a component thereof, comprising: 
 an impeller having a plurality of vanes;    an inlet port for permitting liquid to flow into from the outside of the component; and    a duct connected with the inlet port and having a hole such at a position as to face the rotating shaft of the impeller, wherein    liquid flowing into from the inlet port flows into the inside of the component through a hole of the duct by the rotation of the impeller.    
   
   
       5 . The liquid circulation system according to  claim 4 , comprising: 
 a bottom wall for supporting the rotating shaft of the impeller; and    electromagnets mounted on the opposite side to the impeller on the bottom wall, wherein    the impeller is rotated by the electromagnets and permanent magnets included in the impeller.    
   
   
       6 . The liquid circulation system according to  claim 5 , wherein 
 the bottom wall includes a liquid sealing member on the same side as the impeller.    
   
   
       7 . The liquid circulation system according to  claim 4 , wherein 
 the liquid passing through the component is a collision jet flow against the inside of the component.    
   
   
       8 . A liquid cooling system for cooling a component with coolant, comprising: 
 the liquid circulation system according to  claim 1 , wherein    the component is the one that performs heat exchange.    
   
   
       9 . A liquid cooling system for cooling a component with coolant, comprising: 
 the liquid circulation system according to  claim 1 , wherein    the component is the one that retains coolant.    
   
   
       10 . A liquid cooling system for cooling a component with coolant, comprising: 
 the liquid circulation system according to  claim 4 , wherein    the component is the one that comes into contact with a heat generating member to cool the heat generating member.    
   
   
       11 . The liquid circulation system according to  claim 1 , including: 
 a pump section having a bottom wall for supporting the rotating shaft of the impeller and electromagnets mounted on the opposite side to the vanes on the bottom wall, wherein    the pump section rotates the impeller by the electromagnets and the permanent magnets included in the impeller.    
   
   
       12 . The liquid circulation system according to  claim 4 , including: 
 a pump section having a bottom wall for supporting the rotating shaft of the impeller and electromagnets mounted on the opposite side to the vanes on the bottom wall, wherein    the pump section rotates the impeller by the electromagnets and the permanent magnets included in the impeller.
