Vehicle heating system

Abstract

Abstract PURPOSE:To improve the qualities of instant heating and pleasantness at a heat pipe type exhaust heat heating system, by detecting an engine cooling water temperature and a heat pipe temperature, and arranged so that a fan may be started when either of the two temperatures surpasses a predetermined value. CONSTITUTION:In the case of a heat pipe switch 37 being ON, respective detection temperatures from the cooling water temperature sensor 15 of an engine 1 and the steam temperature sensor 18 of a heat pipe 8 are inputted into a controller 38. The controller 38 compares the detection temperatures inputted from both sensors 15, 18 with a predetermined value. And, when both temperatures are together less than the predetermined value, a fan 11 is not started. However, when either of the water temperature and the heat pipe temperature surpasses the predetermined value, the controller 38 starts the fan 11. As a result, the quality of instant heating is improved, and the quality of pleasantness can be improved.
