摘要： To reduce the width of variations in temperature of circulating liquid due to a variation in a heat load of an external device to a low level to stabilize the performance of the external device in a constant temperature liquid circulating device. In a constant temperature liquid circulating device that connects a piping of circulating liquid in an external device between a discharge port and a return port of a conduit for delivering the circulating liquid at a constant temperature by a pump, a flow amount sensor and temperature sensors for detecting discharge temperature (T1) of the circulating liquid from the conduit and the return temperature (T2) of the circulating liquid are provided in the conduit, so that the flow amount and the temperature of the circulating liquid is controlled by a controller according to the heat load of the external device obtained on the basis of the outputs from the temperature sensors. The control is such that when the difference between the discharge temperature and the return temperature is smaller than the preset value, the temperature of the circulating liquid is controlled corresponding to the heat load, and when the temperature difference is larger than the preset value, the temperature of the circulating liquid is controlled corresponding to the heat load by increasing the flow amount of the circulating liquid to the piping of the external device in addition to the temperature control described above.

摘要： To provide a water-cooled constant temperature liquid circulating device in which the stability in temperature of circulating liquid can be improved by optimizing a flow channel of radiating water and a method of controlling the temperature of circulating liquid in the same device. In a water-cooled constant temperature liquid circulating device in which a heat exchange portion of the radiator tube, in which radiating water which is controlled in flow amount flows therein, is attached to a tank, a pump is provided in a conduit which allows the circulating liquid in the tank to circulate through the external device, and constant temperature circulating liquid is delivered into the piping in the external device by the pump, comprising: an electric proportional valve for controlling the flow amount of radiating water to be delivered to the heat exchange portion of the radiator tube and an electromagnetic valve for delivering the radiating water, which is controlled in flow amount by the electric proportional valve, to the heat exchange portion in an optimal flow amount regulated by controlling the opening-closing duration thereof. The electric proportional valve is controlled to a flow amount suitable for heat exchange with respect to circulating liquid at the heat exchange portion and equal to, or larger than, a low flow limit value that can be controlled by the electric proportional valve, or to an amount slightly larger than that value.
