  • Hydrogen combustion heater
    Publication number: 20050142507
    Abstract: The invention relates to a hydrogen combustion heater. This heater includes (a) a passage for allowing hydrogen gas and air to flow therethrough; (b) a first catalyst provided in the passage, the first catalyst being heated, when electricity is applied thereto, thereby starting a first combustion of a first mixture of the hydrogen gas and the air in the first catalyst; and (c) a heat exchanger provided downstream of the first catalyst in the passage, the heat exchanger being adapted to transfer heat generated by the first combustion to a heating medium of the heat exchanger.
    Type: Application

  • Safety device
    Patent number: 4865249
    Abstract: A safety device for an engine cooling system having a heater core circuit for circulating the engine cooling water through the heater core of an automotive air conditioning system, and a radiator circuit for circulating the engine cooling water through a radiator. The safety device comprises a safety valve provided in the heater core circuit and capable of discharging the engine cooling water outside the vehicle when the temperature of the engine cooling water exceeds a predetermined temperature and/or when the pressure of the engine cooling water exceeds a predetermined pressure.
