<p>A positive temperature coefficient thermistor device adapted for a heating apparatus comprises a board-type positive temperature coefficient thermistor element (7) and a first and a second radiator (HR1, HR2) for radiation adjacently disposed on a front and a rear surface (7a, 7a) of the thermistor element (7), respectively. Each of these radiators (HR1, HR2) has a pair of fitting flanges (1a,1b; 3a,3b) which are, respectively, arranged on a pair of opposed sides of each radiator(HR1,HR2) located so as to meet at right angles with a flow direction of the air to be heated by the positive temperature coefficient thermistor device. Corresponding fitting flanges (1a,3a; 1b,3b) of the first and second radiators (HR1, HR2) are engaged with each other by respective spring pin members (9) which are, respectively, inserted between the surfaces of the facing flanges (1a,3a; 1b,3b) so as for them to be united. The thermistor element (7) is contained in a space surrounded by the first and second radiators (HR1,HR2).</p> |
