Abstract

Abstract The apparatus circulates cooling fluid through a plura­lity of cooling modules (11) for cooling electronic components (33), such as IC or LSI. A plurality of cooling fluid supply systems are independently connected to the respective cooling modules (11), and each of the supply systems includes a fluid line (7a, 7b, ...) connected to a single tank (2) containing cooling fluid and provided with a pump (3) and a heat exchanger (5), so that the cooling fluid in the tank is circulated through the respective cooling modules (11) and returned to the tank (2), in which the cooling fluid is then mixed.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 93 words
An apparatus for supplying cooling liquid for circulation through a plurality of cooling modules for cooling electronic components, comprising: fluid; a single tank for containing cooling a plurality of cooling fluid supply systems independently connected to said plurality of cooling modules; each of said cooling fluid supply systems including a fluid line connected to said tank and provided with at least one pump and a heat exchanger, to circulate the cooling fluid from said tank through said respective cooling modules and back to said tank, in which the cooling fluid is then mixed.
Claim 2
Independent Claim 93 words
An apparatus for supplying cooling liquid for circulation through a plurality of cooling modules for cooling electronic components, comprising: fluid; a single tank for containing cooling a plurality of cooling fluid supply systems independently connected to said plurality of cooling modules; each of said cooling fluid supply systems including a fluid line connected to said tank and provided with at least one pump and a heat exchanger, to circulate the cooling fluid from said tank through said respective cooling modules and back to said tank, in which the cooling fluid is then mixed.
Claim 3
Dependent Claim 20 words
An apparatus according to claim 1, wherein said tank containing said cooling fluid is provided with a liquid cleaning means.
Claim 4
Dependent Claim 50 words
An apparatus according to claim 2, wherein said liquid cleaning means comprises a further fluid line connected to said tank and provided with a pump and. a liquid cleaning element, so that said cooling fluid from said tank is circulated through said liquid cleaning element when returned to said tank.
Claim 5
Dependent Claim 39 words
An apparatus according to claim 3, wherein said liquid cleaning element comprises at least one of a filter for removing foreign substances from the cooling fluid and an ion exchanger for neutralizing metal ions contained in the cooling fluid.
Claim 6
Dependent Claim 31 words
An apparatus according to claim 3, wherein both ends of said further fluid line are connected to said tank and said pump of said liquid cleaning means is an exclusive-use pump.
Claim 7
Dependent Claim 91 words
An apparatus according to claim 3, wherein said further fluid line comprises a pipe provided with said liquid cleaning element and having one end con­nected to said tank and the other end connected to the fluid line of one of said cooling fluid supply systems, at a point downstream of the pump of said cooling fluid supply system, so that said pump not only circulates the cooling fluid through said cooling fluid supply system, but also circulates a part of the cooling fluid through said pipe of said further fluid line.
Claim 8
Dependent Claim 16 words
