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.
