Abstract:
1. A system for controlling temperature of a liquid in a small flow amount, comprising: a supply path connected to a supply source of the liquid and including a regulator for pressurizing the liquid supplied from the supply source; a circulation path connected to the supply path and for circulating the liquid pressurized by the regulator in a pressurized condition by a pump; a temperature control device for performing a temperature control operation for the liquid circulating in the circulation path upon intervening in the circulation path; and a discharge path provided with a discharge valve for supplying the temperature-controlled liquid in the circulation path to an exterior device as a consecutive flow in a small amount or an intermittent flow in a small amount in a flow amount less than at least ½ times the flow amount in the circulation path upon branching from the circulation path, wherein the discharge path is formed from a double tube-type heat exchanger, and a tube for causing to flow all of or a part of the liquid flowing in the circulation path is connected to the outer tube of the double tube-type heat exchanger.
