Electronic apparatus

Abstract

An electronic apparatus includes a case mounting a semiconductor element therein, a heat-receiving member thermally connected with the semiconductor element, a heat-radiation member disposed on an inner side surface of the case, and a liquid driver which drives a liquid coolant between the heat-radiation member and the heat-receiving member. The apparatus further includes a tank accumulating the liquid coolant therein and having at least a predetermined volume of the coolant to delimit a coolant surface within the tank. The tank, the heat-radiation member and the heat-receiving member are connected with tubes, and a suction end portion of a suction pipe connected into the tank is located at a position which is always below the coolant surface irrespective of change of position of the tank.

1 . An electronic apparatus, comprising: 
 a case mounting a semiconductor element therein;    a heat-receiving member thermally connected with said semiconductor element;    a heat-radiation member disposed on an inner side surface of said case;    a liquid driver which drives a liquid coolant between said heat-radiation member and said heat-receiving member; and    a tank accumulating said liquid coolant therein and having at least a predetermined volume of said coolant so as to delimit a coolant surface within said tank, wherein said tank, said heat-radiation member and said heat-receiving member are connected with tubes; and    a suction end portion of a suction pipe connected into said tank is located at a position which is always below the coolant surface irrespective of change of position of said tank.    
   
   
       2 . An electronic apparatus according to  claim 1 , wherein an inside of said tank is partially divided into multiple portions by at least two pieces of partition plates which do not inhibit liquid coolant flow among the multiple portions, and said suction end portion of said suction pipe is located between at least two pieces of the partition plates.  
   
   
       3 . An electronic apparatus according to  claim 2 , wherein a gap is provided between an inner surface of said tank and each of said partition plates, said multiple portions being communicable with one another.  
   
   
       4 . An electronic apparatus according to  claim 1 , wherein said tube connecting into said tank has a flow inlet and a flow outlet, and a nozzle for injecting said liquid coolant through pushing out air within said tube is connectable to said flow inlet and said flow outlet.  
   
   
       5 . An electronic apparatus according to  claim 2 , wherein said tube connecting into said tank has a flow inlet and a flow outlet, and a nozzle for injecting said liquid coolant through pushing out air within said tube is connectable to said flow inlet and said flow outlet.  
   
   
       6 . An electronic apparatus according to  claim 3 , wherein said tube connecting into said tank has a flow inlet and a flow outlet, and a nozzle for injecting said liquid coolant through pushing out air within said tube is connectable to said flow inlet and said flow outlet.
