A liquid cooling apparatus for use in a disk array apparatus which contains a plural number of units having a disk drive inside of a housing and disposed within a rack, including an air-blow fan, a pump for transmitting liquid coolant, a radiator for transmitting heat absorbed into the liquid coolant into outside air, and pipes for connection of the pump and radiator. The liquid cooling apparatus further includes a temperature sensor disposed at a position for detecting temperature of the liquid coolant, which temperature changes in response to electric power consumed within the plural number of disk drives, and a rotation speed of the pump is controlled in dependence upon a detection signal from the temperature sensor.

What is claimed is: 1. A disk array apparatus, comprising: a plural number of units, each containing at least one disk drive into an inside of a housing; and a rack for containing the plural number of units within an inside thereof, wherein said unit comprises a controller for controlling each of s
What is claimed is: 1. A disk array apparatus, comprising: a plural number of units, each containing at least one disk drive into an inside of a housing; and a rack for containing the plural number of units within an inside thereof, wherein said unit comprises a controller for controlling each of said at least one disk drive within said unit and an air-blow fan, as well as, a liquid cooling system having, a pump for transmitting a liquid coolant, a radiator for transmitting heat absorbed into the liquid coolant into an outside air, and pipes for connecting those, said liquid cooling system is connected thermally with, at least said controller for said at least one disk drive and a part of said unit adjacent said at least one disk drive for enabling cooling of said at least one disk drive, and further a rotation speed of said pump is controlled depending on a detection signal from a temperature sensor, which is provided in a part of said liquid cooling system, for detecting a temperature of the liquid coolant, which changes in response to electric power consumed within said controller and said at least one disk drive of said plural number of units, wherein the rotation speed of said pump is controlled independently of any other control of said disk array apparatus including control of said air-blow fan. 2. The disk array apparatus, as described in the claim 1, wherein the pipes of said liquid cooling system within each of said units are further provided within a power source portion of said unit. 3. The disk array apparatus, as described in the claim 1, wherein said temperature sensor within each of said units is provided in a part of the pipes, which build up said liquid cooling system. 4. The disk array apparatus, as described in the claim 2, wherein said temperature sensor within each of said units is provided in a part of the pipes, which build up said liquid cooling system. 5. The disk array apparatus, as described in the claim 1, wherein the part adjacent said at least one disk drive is a cooling jacket which is provided within each of said units, being thermally connected with the plural number of units containing said at least one disk drive and contained within said housing, and is connected to said pipes, thereby building up a part of said liquid cooling system. 6. The disk array apparatus, as described in the claim 1, wherein further a cooling jacket is provided within each of said units, for cooling said controller, and is connected to said pipes, thereby building up a part of said liquid cooling system. 7. The disk array apparatus, as described in the claim 5, wherein further a cooling jacket is provided within each of said units, for cooling said controller, and is connected to said pipes, thereby building up a part of said liquid cooling system. 8. The disk array apparatus, as described in the claim 1, wherein said temperature sensor is provided in vicinity of an inlet of said radiator within each of said units. 9. The disk array apparatus, as described in the claim 5, wherein said temperature sensor is provided in vicinity of an inlet of said radiator within each of said units. 10. The disk array apparatus, as described in the claim 1, wherein the detection signal from said temperature sensor within each of said units is directly inputted into a controller portion of said pump building up said liquid cooling system within each of said units. 11. The disk array apparatus, as described in the claim 5, wherein the detection signal from said temperature sensor within each of said units is directly inputted into a controller portion of said pump building up said liquid cooling system within each of said units. 12. The disk array apparatus, as described in the claim 1, wherein a partition is provided within an inside of each of said units, thereby separating said liquid cooling system in spaces thereof. 13. The disk array apparatus, as described in the claim 5, wherein a partition is provided within an inside of each of said units, thereby separating said liquid cooling system in spaces thereof. 14. A liquid cooling apparatus for use in a disk array apparatus, containing a plural number of units, each containing at least one disk drive into an inside of a housing, within a rack, comprising: an air-blow fan; a pump for transmitting a liquid coolant; a radiator for transmitting heat absorbed into the liquid coolant into an outside air; a part adjacent said at least one disk drive for enabling cooling thereof; pipes for connection of at least said pump, said radiator and said part; and a temperature sensor for detecting temperature of the liquid coolant; wherein said temperature sensor is disposed at a position so as to detect the temperature of the liquid coolant, which changes in response to electric power consumed within said at least one disk drive of said plural number of units; wherein a rotation speed of said pump is controlled depending upon a detection signal from said temperature sensor; and wherein the rotation speed of said pump is controlled independently of and other control of said disk array apparatus including control of said air-blow fan. 15. The liquid cooling apparatus, as described in the claim 14, wherein said part includes a cooling jacket, which is thermally connected with said at least one disk drive of the plural number of units contained within said housing, wherein said cooling jacket is connected to said pipes.
