<p>PURPOSE:To uniformize temperatures of coolants sent out from supporting ports by respectively providing the supplying ports and returning ports at the central part of the bottom section of a tank and outer peripheral section of the part where the supplying ports are provided so that the coolants can form a vortex and setting the directions of the returning ports so that the vortex can be made stronger. CONSTITUTION:Supporting ports (5-1)-(5-N) and returning ports (4-1)-(4-N) are respectively provided at the central part 2A of the bottom section 2 of a container 1 and at the outer peripheral section 2B of the section 2A where the ports (5-1)-(5-N) are provided so that a coolant preserved in the container 1 can form a vortex in a prescribed direction when the coolant 3 flows out through the returning ports (4-1)-(4-N) and, at the same time, the directions of the pots (4-1)-(4-N) are set in the directions in which the vortex can be made stronger. Therefore, even when the coolant 3 having a temperature difference is returned from the ports (4-1)-(4-N), the temperature variation of the coolant 3 can be eliminated by means of the agitating effect of the vortex. As a result, coolants 3 of a prescribed uniform temperature can be supplied from the supplying ports (5-1)-(5-N).</p> |
