Heating device
View Patent ↗A heating device includes a heater ( 2 ) having a heating portion ( 6 ) which generates heat by energization; a housing ( 4 ) which contains the heating portion and forms a passage ( 18 ) for a heating medium between the housing and the heating portion; a temperature sensor ( 26 ) for detecting the temperature of the heating medium in the passage; and an inverter for interrupting energization of, that is, the carrying of current to, the heater depending on the temperature of the heating medium detected by the temperature sensor. The temperature sensor is brought into contact with the heating portion.
1. A heating device for use in a motor vehicle as a source of heat within the motor vehicle, comprising:
a heater having a heating portion which generates heat by energization;
a housing which contains the heating portion and forms a passage for a heating medium between the housing and the heating portion;
a temperature detection means for detecting the temperature of the heating medium in the passage; and
an energization interrupting means for interrupting the carrying of current to the heater depending on the temperature of the heating medium detected by the temperature detection means,
wherein the temperature detection means is brought into contact with the heating portion, and
wherein the housing comprises one or more cast bodies.
2. The heating device according to claim 1 , wherein the temperature detection means comes into surface contact with the heating portion.
3. The heating device according to claim 1 , wherein the temperature detection means is connected to the housing via a seal member.
4. The heating device according to claim 3 , wherein a plurality of the seal members are provided.
5. The heating device according to claim 2 , wherein the temperature detection means is connected to the housing via a seal member.
6. The heating device according to claim 5 , wherein a plurality of the seal members are provided.
