Abstract

A cooling system includes a heat absorbing device which has a first pipe port and absorbs heat discharged from equipment by using refrigerant; a radiator which has a second pipe port placed higher than the first pipe port and cools the refrigerant; a first flexible pipe whose one end is connected with the first pipe port and whose another end is connected with the second pipe port and through which the refrigerant flows and which can bend freely; and a loading table having a surface which becomes higher in a vertical direction as approaching from one end of the surface to another end, and on which the first flexible pipe is placed so as to become higher in the vertical direction as approaching from a side of the first flexible pipe, which is connected with the first pipe port, to a side of the first flexible pipe which is connected with the second pipe port.

First claim

The invention claimed is:

1. A cooling system comprising:
a heat absorbing device which has a first pipe port and absorbs heat discharged from equipment by using refrigerant;
a radiator which has a second pipe port placed higher than the first pipe port and cools the refrigerant;
a first flexible pipe that is bendable and serves as a flow path of the refrigerant, the first flexible pipe being connected to the first pipe port at one end and the second pipe port at another end; and
a loading table having a surface that rises in a vertical direction as a corresponding position onto the surface approaches from one end of the surface to another end, the surface supporting the first flexible pipe placed thereon in such a way that the first flexible pipe rises in the vertical direction as a corresponding position on the first flexible pipe approaches from a side connected to the first pipe port to a side connected to the second pipe port.

2. The cooling system according to claim 1 , further comprising:
a second flexible pipe that is bendable and serves as a flow path of the refrigerant, wherein
the heat absorbing device further includes a third pipe port and absorbs the heat discharged from the equipment by evaporating the refrigerant, wherein
the radiator further includes a fourth pipe port, which is placed higher than the third pipe port, and condenses the evaporated refrigerant by cooling the evaporated refrigerant, wherein
the second flexible pipe is connected to the third pipe port at one end and the fourth pipe port at another end, wherein
the loading table has the surface supporting the second flexible pipe placed thereon in such a way that the second flexible pipe rises in the vertical direction as a corresponding position on the second flexible pipe approaches from a side connected to the third pipe port to a side connected to the fourth pipe port, wherein
the first flexible pipe is a path through which the refrigerant evaporated by the heat absorbing device is conveyed to the radiator, and wherein
the second flexible pipe is a path through which the refrigerant condensed by the radiator is conveyed to the heat absorbing device.

3. The cooling system according to claim 1 , wherein
each of the first and the second flexible pipes has a bent portion when being placed on the loading table and bends freely in response to a movement of the heat absorbing device.

4. The cooling system according to claim 1 , further comprising:
a cart to which one end of each of the first and the second flexible pipes is fixed, the cart being movable in response to a movement of the heat absorbing device.

5. The cooling system according to claim 1 , wherein
the loading table is placed onto a surface which is positioned higher than the heat absorbing device.

6. The cooling system according to claim 1 , wherein
the loading table is hung from a place higher than a place of the heat absorbing device.

7. The cooling system according to claim 2 , further comprising:
a pressure gauge which measures pressure of the evaporated refrigerant; and
a pressure regulator which regulates the pressure based on the pressure measured so as to be in a prescribed state.

8. Electronic equipment, comprising:
the cooling system according to claim 1 .
