Water tray of liquid based cooling device

Abstract

Disclosed is a water tray for a liquid based coolant device that includes a pump for circulating a liquid coolant between the water tray that is positionable on a heat generating device and a radiator that dissipates heat into the surrounding. The water tray includes a housing on which coolant inlet and outlet are formed for receiving the coolant from the pump and discharging the coolant to the radiator. The water tray also forms a recess in which a base is received in a liquid tight manner. The base defines a spiral coolant channel having ends respectively in fluid communication with the inlet and outlet for guiding the coolant from the inlet to the outlet to absorb and remove heat from the heat generating device.

1 . In a liquid based cooling device comprising a pump for circulating a liquid coolant between a water tray that is positionable on a heat generating device to remove heat therefrom by the coolant flowing through the water tray and a radiator that dissipates heat carried by the coolant into the surrounding, the water tray comprising: 
 a housing having defining a recess, and the housing forming an inlet for receiving the coolant and an outlet through which the coolant discharges; and    a base received in the recess in a liquid tight manner, the base defining a spiral channel having first and second ends respectively in fluid communication with the inlet and outlet whereby the coolant is allowed to flow along the channel from the inlet to the outlet.    
   
   
       2 . The water tray as claimed in  claim 1 , wherein the base and the housing are secured together by fasteners.  
   
   
       3 . The water tray as claimed in  claim 1 , wherein the base has a surface that is exposed for positionability on and physical contact with the heat generating device.
