Abstract: A system for testing objects such as electronic devices and mechanical components to see how they can withstand thermally hard circumstances created by a thermal agent supplied from a supplying system communicating with a testing section by and through an inlet flow path and an outlet flow path, wherein heat exchange is effected between the incoming agent and the outgoing agent, so that the remaining heat content, worm or cold, is taken and utilized for later uses.

Abstract: A thermostat includes a plate body, a heat insulator, and an electric heater. The plate body defines a cavity therewithin. The plate body has on its bottom two openings, which communicate with the cavity and function as a cooling medium inlet and a cooling medium outlet, respectively. The outer periphery of the plate body is covered with the heat insulator. That prevents heat intrusion and/or dissipation from the outer periphery of the plate body in transferring heat between the mounting face and a heat transfer medium within the cavity. That reduces the thermal influence on the mounting face, thereby ensuring more uniform temperature distribution on the mounting face.

Abstract: In one example, a piping system 20 is built around a wire (elongated flexible member) 25. An inlet pipe 21 and an outlet pipe 22 are fixed to both sides of the wire 25 parallel to each other via a plurality of pipe holders 26. Further, insulator holders 27 are attached to the wire 25 and heat insulating sections 28 are attached to the insulator holders 27. A cylindrical gap 51 is formed between the inlet pipe 21 and the inner surface of each of the heat insulating section 28.

Abstract: A disc-type unit 10 adjusts temperature of a control face 14 by means of a heater 12 and coolant, with a hollow plate 11 to which the heater 12 is secured, a cavity 13 formed in the hollow plate 11 and a piping 20 for supplying the coolant to the cavity 13, the piping 20 opening in the cavity 13, and the coolant being jetted to a portion to which the heater 12 is secured or a portion in proximity thereto and which shows high temperature rise when energizing the heater 12.
