A temperature detection element of a temperature sensor is connected to a print wire and three print wires for an input and output of a print substrate, one end of a lead wire for a connection is connected and fixed with solder to an external circuit for connection electrodes of the print wire, and the other end is externally drawn out of a sealing member of a hardened resin. Within the housing, the entire bottom surface of the print substrate is supported by a lower fixed member, and an end, closer to an opening part of the housing, of the print substrate, is sandwiched and fixed by an upper fixed member and the lower fixed member. The housing is configured with the same material and size as the housing of the temperature control element, and the temperature detection element inside is placed at a position approximated to a placement of a thermal response element of the temperature control element. By using an adhesive having a different thermal conductivity, a thermal characteristic of the temperature sensor can be varied.

A thermally responsive element in which the degree of freedom in setting a differential is high across a wide range of temperature zones and a relatively small differential is settable is provided. The element may be a plate-like member having a shape that changes in accordance with a temperature change. A cross-section of the thermally responsive element at room temperature may have a compound curved shape. A cross-section of the thermally responsive element after the shape change may have a compound curved shape. A border between the central portion and the outer peripheral portion is the same before and after the shape change of the thermally responsive element.

A thermally-controlled component and thermal control process are disclosed. The thermally-controlled component includes thermally-responsive features. The thermally-responsive features are configured to modify a flow path to control temperature variation of the thermally-controlled component. The thermally-responsive features deploy from or retract toward a surface of the thermally-controlled component in response to a predetermined temperature change. The thermal control process includes modifying the flow path in the thermally-controlled component to control temperature variation of the thermally-controlled component and/or cooling a region of the thermally-controlled component through the thermally-responsive features deploying from or retracting toward a surface of the thermally-controlled component.
