ABSTRACT:
An electric heating module includes an electric heater (10), a heat pipe (20) having an evaporating section (22) thermally attached to the electric heater and a condensing section (24), and at least one heat radiator (30, 40) thermally attached to the condensing section. The electric heater includes a pair of electrode plates (12, 14) and a heating element (16) sandwiched between and electrically connecting the electrode plates. An insulation frame (19) encloses the electrode plates therein for electrically insulating the electric heater from the heat radiator. For the non-linear PTC heating element, the electric heater can rapidly heat up to and stay at a desired stable temperature. The heat pipe can transfer heat from the electric heater to the heat radiator rapidly and timely by phase change.
