Cooling unit

Abstract

A cooling unit includes: at least one pump that circulates coolant; a tank having a first inlet through which coolant is caused to flow in and at least one first outlet through which the coolant is expelled to the at least one pump; and an air bubble accumulating portion provided in an upper part of the tank, wherein the first inlet is disposed at a position such that the coolant is caused to flow into the air bubble accumulating portion, and the at least one first outlet is provided below the air bubble accumulating portion.

1 . A cooling unit comprising:
 at least one pump that circulates coolant;   a tank having a first inlet through which coolant is caused to flow in and at least one first outlet through which the coolant is expelled to the at least one pump; and   an air bubble accumulating portion provided in an upper part of the tank,   wherein the first inlet is disposed at a position such that the coolant is caused to flow into the air bubble accumulating portion, and   the at least one first outlet is provided below the air bubble accumulating portion.   
     
     
         2 . The cooling unit according to  claim 1 , wherein
 the at least one pump comprises a plurality of pumps,   the at least one first outlet comprises a plurality of first outlets, and   the tank further has at least one mixing chamber having a plurality of second inlets connected to outlets of the plurality of pumps.   
     
     
         3 . The cooling unit according to  claim 2 , wherein
 the at least one mixing chamber has a second outlet through which the coolant flowing in through the plurality of second inlets is expelled, and   a circulation loop that leads from the second outlet to the first inlet and circulates the coolant is connected to the at least one mixing chamber.   
     
     
         4 . The cooling unit according to  claim 3 , wherein
 a radiating fin that cools the coolant, and   a cooling member that absorbs heat from a heat-generating component with the coolant are connected to the route of the circulation loop.   
     
     
         5 . The cooling unit according to  claim 2 , wherein
 the at least one mixing chamber comprises a plurality of mixing chambers, and   the tank further has a second mixing chamber in which the coolant from the plurality of mixing chambers is mixed.
