Integrated circuit package having a cooling mechanism

An integrated circuit package having a cooling mechanism, comprising;

• a printed wiring board;
• a plurality of integrated circuit chips disposed on said printed wiring board in a matrix;
• cooling means, disposed corresponding to said integrated circuit chips, for cooling said integrated circuit chips using jet impingement of liquid coolant, wherein said cooling means comprises
• a cooler plate in contact with the top face of a respective integrated circuit chip,
• a cylinder-shaped housing with an end fixed to said cooler plate,
• a nozzle inserted into said housing to jet said liquid coolant to substantially the center of said cooler plate, and
• a drain tube disposed at said housing to drain said liquid coolant jet into said housing;
• holding means, in fixed relationship to said printed wiring board, for positioning and holding said cooling means corresponding to said integrated circuit chips, wherein said holding means has positioning holes to hold said cooling means with their top part projecting at the positions corresponding to said integrated circuit chips;
• pressing means for pressing said cooling means against said integrated circuit chips with force of a predetermined level;
• a supplying manifold which is provided with an inlet for liquid coolant supplied from outside said integrated circuit package and distributes the liquid coolant to each row of cooling means;
• a draining manifold which collects the liquid coolant flowing from said rows of cooling means and is provided with an outlet to drain such liquid coolant;
• and
• connecting tubes to connect said supplying manifold and draining manifold with the rows of cooling means and to connect adjacent cooling in each row.
