<p><P>PROBLEM TO BE SOLVED: To provide a thermostat capable of minimizing a temperature difference with a set temperature when carrying out temperature control by using a constant temperature liquid supplying device. <P>SOLUTION: The thermostat is characterized by that it is provided with an outer tube 2 with an interior provided as a sealed space, a supply port 201 formed in a one end vicinity in the outer tube 2, a discharge port 202 formed in another end vicinity in the outer tube 2, an inner tube 3 inserted in the outer tube 2 and built with a heater 4 in an interior, and a stream lining means circumferentially provided in a spiral state in an outer circumference side of the inner tube 3. Thereby, since an air pressure and a liquid medium supplied into the outer tube are guided by a partition plate to the discharge port in a volute state around an outer circumference side of the inner tube while being agitated during the process, wholes of the air pressure and the liquid medium are uniformly brought into contact with the inner tube, and the wholes of the air pressure and the liquid medium are evenly heated to a set temperature, ultraprecise temperature control of a device or the like can be carried out. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
