Abstract

A cooling system of an electronic device storing apparatus of the present invention comprises: a rack including an electronic device and a plurality of placement shelves to place the electronic device; in the rack, a vaporizer having a refrigerant internally being mounted; outside the rack, a condensing part connected with the vaporizer by a laying pipe being installed; and a refrigerant adjustment means for adjusting a height of a refrigerant surface in the vaporizer.

Claims (25)

1. A cooling system for an electronic device storing apparatus, comprising:

a rack including a plurality of placement shelves to place an electronic device;

a plurality of vaporizers having a refrigerant internally and being mounted in said rack;

a condensing part being installed outside said rack and connected with said plurality of vaporizers by a laying pipe;

a plurality of tanks, each storing said refrigerant and being connected to each of said plurality of vaporizers by a heat exchanger connecting pipe;

a plurality of tank connecting pipes connecting said plurality of tanks;

a condenser pipe connecting one of said plurality of vaporizers and said condensing part; and

a refrigerant adjustment means for adjusting a height of refrigerant surface in said plurality of vaporizers,

wherein said refrigerant adjustment means has a means for controlling a height of said plurality of tanks.

2. The cooling system of an electronic device storing apparatus according to claim 1 ,

wherein said refrigerant adjustment means is provided with a plurality of fluid control devices each being connected to said condensing part and being connected to a different height of said plurality of tanks.

3. The cooling system of an electronic device storing apparatus according to claim 1 , comprising

a temperature sensor to detect temperature of said rack; and, according to a detection result of said temperature sensor, controlling said refrigerant adjustment means for adjusting a height of said refrigerant surface.

4. A cooling system for an electronic device storing apparatus, comprising:

a rack including a plurality of placement shelves to place an electronic device, said rack being arranged in a building, being installed with a plurality of air intake openings and air exhaust an outside air;

a plurality of vaporizers, each vaporizer having a refrigerant internally and being mounted in said rack;

a condensing part begin installed outside said rack and connected with said plurality of vaporizers by a laying pipe;

a plurality of tanks, each storing said refrigerant and being connected to each of said plurality of vaporizers by a heat exchanger connecting pipe;

a plurality of tank connecting pipes connecting said plurality of tanks;

a condenser pipe connecting one of said plurality of vaporizers and said condensing part; and

a refrigerant adjustment means for adjusting a height of a refrigerant surface in said plurality of vaporizers,

wherein said refrigerant adjustment means has a means for controlling a height of said plurality of tanks.

5. The cooling system of an electronic device storing building according to claim 4 , wherein a fan is provided in an air exhaust opening of said electronic device storing building.

6. The cooling system of an electronic device storing building according to claim 4 ,

wherein a temperature sensor to detect temperature of said rack is provided, and, according to a result of said temperature sensor, output of said fan of said electronic device storing building and said refrigerant adjustment means are controlled.
