Liquid cooling module

Abstract

A liquid cooling module has a sealed unit and a heat dissipating module connected by multiple flexible pipes. The sealed unit has a contacting surface attached to an electronic element. The heat dissipating module has a radiator, coolant tanks and a pump all mounted compactly together. The radiator has multiple fins and tubes to allow the coolant to flow through and dissipate heat and may have a fan to increase airflow. The coolant tank is formed on the radiator. The pump circulates the coolant along the coolant pipes. Accordingly, the liquid cooling module has a compact structure and the coolant pipes are flexible, so the liquid cooling module can be mounted simply in a computer case, and is installed easily by home users and professionals alike.

 a side wall; 
 an inlet being formed through the side wall; 
 an outlet being formed through the side wall; 
 a partition being mounted securely in the lower tank and defining
 a cool chamber communicating with half of the flow channels of the warm and cold tubes; and 
 a hot chamber communicating with the other half of the flow channels of the warm tubes and the inlet; 
 
   wherein the tubes are further formed between the upper and lower tanks and through the bottom cover; and   the pump is mounted in the cool chamber and further has
 a pump case having
 a top surface; 
 a pump partition being mounted sealably in the cool chamber between the bottom cover and the pump case; 
 a pump chamber being defined between the pump case, pump partition and bottom cover and communicating with half of the cold tubes; 
 a pump inlet being formed through the top surface of the pump case and communicating with the pump chamber; 
 a pump exhaust being formed on and protruding from the pump case, communicating with the pump chamber via the pump inlet and being mounted sealably in the outlet of the lower tank; and 
 
   wherein the inlet pipe is further connected to the inlet of the lower tank; and   the outlet pipe is further connected to the outlet of the lower tank.   
   
   
       4 . The liquid cooling module as claimed in  claim 3 , wherein the pump is an impeller pump having a pump assembly mounted in the pump case. 
   
   
       5 . The liquid cooling module as claimed in  claim 4 , wherein the heat dissipating module further comprising a fan being securely mounted adjacent to the front of the radiator to increase airflow flowing through the fins of the radiator to increase heat dissipation. 
   
   
       6 . The liquid cooling module as claimed in  claim 5 , wherein the sealed unit further has
 a lid;   a mounting board being mounted sealably on the lid;   and multiple inner fins being formed on the mounting board in the chamber of the sealed unit;   wherein the contacting surface is formed on the mounting board.   
   
   
       7 . The liquid cooling module as claimed in  claim 6 , wherein
 the sealed unit further has an outlet seat and an inlet seat being formed separately through the lid of the sealed unit and communicating with the chamber;   wherein the outlet pipe is further connected to the outlet seat of the sealed unit; and   the inlet pipe is further connected to the inlet seat of the sealed unit.   
   
   
       8 . The liquid cooling module as claimed in  claim 7 , wherein
 the upper tank further has
 a coolant input being formed through the top of the upper tank for adding coolant; and 
 a cap being securely mounted detachably on the coolant input of the upper tank. 
   
   
   
       9 . The liquid cooling module as claimed in  claim 8 , wherein
 the coolant input of the upper tank is threaded; and   the cap is threaded to correspond to the coolant input.
