Title:
VEHICULAR HEATING SYSTEM
Document Type and Number:
Japanese Patent JP3774991
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To shorten the heating risetime and limit the mounting space in vehicles of a vehicular heating system.
SOLUTION: Since catalytic combustion produces clean combustion gas and less soot, the same constitution of a hot-water heating heat exchanger core part for heat exchange between combustion gas and hot water as that of a heat exchanger core part for heat exchange between the hot water and heating air has no disadvantages in terms of its use. From that standpoint, a heat exchanger 10 for heat exchange between hot water and heating air to heat the air up is integrated with a first core part 19 for heat exchange between combustion gas from a combustion chamber 31 and hot water to heat the water up and with a second core part for heat exchange between the hot water and heating air; the first core part 19 is arranged on the upstream side of hot water and the second core part is on the downstream side. The hot water heated up with combustion gas in the first core part 19 is immediately fed into the second core part, where it is subjected to heat exchange with heating air to heat the air up.
