Liquid cooling system

Abstract

In some embodiments, a cooling device may be mounted to a portion of a chassis of an electronic system, wherein the cooling device may be releasably and pivotably attached to the chassis in at least an open position to permit access to components within the electronic system and a closed position to permit installation of a cover on the chassis. Other embodiments are disclosed and claimed.

       3 . The apparatus of  claim 1 , wherein the at least one lock member comprises a pair of lock bumps on the housing.  
   
   
       4 . The apparatus of  claim 1 , wherein the at least one lock member comprises a pair of lock pins on the housing.  
   
   
       5 . The apparatus of  claim 1 , further comprising: 
 at least one stop member disposed on the housing and positioned to cooperate with a corresponding feature on the chassis to inhibit movement of the cooling unit beyond a closed position.    
   
   
       6 . The apparatus of  claim 5 , wherein the at least one stop member comprises a protuberance on the housing.  
   
   
       7 . The apparatus of  claim 5 , wherein the at least one stop member comprises a pair of stop tabs on the housing.  
   
   
       8 . The apparatus of  claim 1 , wherein the housing comprises a shroud and the cooling unit further comprises a heat exchanger and a fan configured to direct air through the shroud and over the heat exchanger.  
   
   
       9 . A method, comprising: 
 positioning a cooling unit on a chassis;    temporarily securing the cooling unit on the chassis in an open position providing access inside the chassis;    moving the cooling unit from the open position to a closed position without removing the cooling unit from the chassis; and    securing the cooling unit in the closed position.    
   
   
       10 . The method of  claim 9 , wherein positioning the cooling unit on the chassis comprises inserting hinge pins on the cooling unit into corresponding mounting blocks on the chassis.  
   
   
       11 . The method of  claim 10 , wherein the moving the cooling unit from the open position to the closed position comprises rotating the cooling unit on the hinge pins.  
   
   
       12 . The method of  claim 9 , wherein the securing the cooling unit on the chassis in the open position comprises providing a lock member on the cooling unit which cooperates with a corresponding structure on the chassis to inhibit undesired movement of the cooling unit.  
   
   
       13 . The method of  claim 12 , wherein the lock member comprises a protuberance on a housing of the cooling unit.  
   
   
       14 . The method of  claim 9 , further comprising: 
 inhibiting the cooling unit from moving inside the chassis beyond the closed position.    
   
   
       15 . The method of  claim 14 , wherein the inhibiting the cooling unit from moving inside the chassis beyond the closed position comprises providing a stop member on the cooling unit which cooperates with a corresponding structure on the chassis to inhibit the movement of the cooling unit beyond the closed position.  
   
   
       16 . The method of  claim 15 , wherein the stop member comprises a protuberance on a housing of the cooling unit.  
   
   
       17 . A system, comprising: 
 a chassis; and    a heat exchanger assembly mounted on the chassis, wherein the heat exchanger assembly comprises: 
 a heat exchanger;  
 a housing for the heat exchanger;  
 positioning pins disposed on the housing for positioning the housing on the chassis during assembly; and  
 at least one lock member disposed on the housing and positioned to cooperate with a corresponding structure on the chassis to temporarily secure the heat exchanger assembly in an open position.  
   
   
   
       18 . The system of  claim 17 , further comprising: 
 a pair of mounting blocks disposed on a side panel of the chassis, wherein the mounting blocks are adapted to receive the positioning pins of the heat exchanger assembly, and wherein the mounting blocks are adapted to engage the at least lock member to temporarily secure the heat exchanger assembly in the open position.    
   
   
       19 . The system of  claim 18 , wherein each mounting block comprises: 
 a first channel adapted to receive one of the positioning pins; and    a second channel adapted to receive the at least one lock member.    
   
   
       20 . The system of  claim 17 , wherein the heat exchanger assembly further comprises: 
 a stop member disposed on the housing and positioned to cooperate with a corresponding feature on the chassis inhibit movement of the heat exchanger assembly beyond a closed position.    
   
   
       21 . The system of  claim 20 , wherein the chassis further comprises: 
 a cross beam positioned between opposed panels of the chassis; and    a blocking member disposed on the cross beam and positioned to block the stop member from moving beyond the closed position when the heat exchanger assembly is moved from the open position to the closed position.    
   
   
       22 . The system of  claim 20 , wherein the chassis further comprises: 
 a cantilever beam attached to a panel of the chassis; and    a blocking member disposed on the cantilever beam and positioned to block the stop member from moving beyond the closed position when the heat exchanger assembly is moved from the open position to the closed position.    
   
   
       23 . The system of  claim 20 , wherein the chassis further comprises:
