Apparatus for cooling heat generating members

An apparatus for cooling heat generating members by dipping or boiling by means of a refrigerant liquid flow, said apparatus for cooling heat generating members comprising:

• first means for branching a portion of a low temperature refrigerant liquid against said heat generating members for cooling said heat generating members and thereby heating said portion of refrigerant liquid to a high temperature and causing boiled bubbles of said refrigerant liquid to occur, and second means for mixing, with each other, another portion of said low temperature refrigerant liquid and said high temperature refrigerant with liquid with boiled bubbles which has cooled said heat generating members to cause boiled bubbles in said high temperature refrigerant liquid to disappear.

An apparatus for cooling heat generating members by means of a refrigerant liquid flow, said apparatus for cooling heat generating members comprising:

• first means for jetting a portion of a low temperature refrigerant liquid into contact with one or a plurality of said heat generating members for cooling the same and thereby heating said refrigerant liquid to a high temperature and causing boiled bubbles of said refrigerant liquid to occur, and second means for directing another portion of said low temperature refrigerant liquid into said high temperature refrigerant liquid with boiled bubbles therein, so that the gas phase from said boiled bubbles in said high temperature refrigerant liquid flow disappears.

An apparatus for cooling heat generating members by means of a refrigerant liquid flow, said apparatus for cooling heat generating members comprising:

• a low temperature refrigerant liquid for cooling heat generating members in a manner which causes boiled bubbles of said refrigerant liquid to occur,
• first nozzles for jetting a portion of said low temperature refrigerant liquid into contact with said heat generating members for cooling said members and heating said portion of refrigerant liquid to a high temperature and causing boiling bubbles of said refrigerant liquid to occur, and
• a means for mixing having second nozzles disposed adjacent to said first nozzles, for jetting another portion of said low temperature refrigerant liquid into a gas-liquid phase of said high temperature refrigerant flow, which has cooled said heating generating members, before it is discharged so the gas phase boiled bubbles in said high temperature refrigerant liquid flow are caused to disappear.
