Heat exchanger for liquid immersion cooling

Abstract

A heat exchanger for liquid immersion cooling includes a first coolant stored in a tank capable of accommodating an electronic component, and configured to cool the electronic component by immersion, an introduction pipe into which a second coolant is introduced from outside of the tank, a discharge pipe from which the second coolant is discharged to outside of the tank, and a plurality of connection pipes coupled between the introduction pipe and the discharge pipe and configured to flow the second coolant from the introduction pipe to the discharge pipe, wherein the heat exchanger is immersed in the first coolant and accommodated in the tank.

         5 . The heat exchanger according to  claim 1 ,
 wherein an interior of each of the plurality of connection pipes is partitioned into a plurality of spaces.   
     
     
         6 . The heat exchanger according to  claim 1 ,
 wherein the plurality of connection pipes are arranged so as to be shifted with respect to the electronic component in a direction intersecting the direction of gravity.   
     
     
         7 . The heat exchanger according to  claim 1 ,
 wherein the first coolant and the second coolant are same type of coolant.   
     
     
         8 . The heat exchanger according to  claim 1 ,
 wherein the first coolant and the second coolant are different types of coolant.   
     
     
         9 . The heat exchanger according to  claim 8 ,
 wherein the first coolant is a fluorine-based insulating coolant and the second coolant is water or a propylene glycol coolant.   
     
     
         10 . A heat exchanger system comprising:
