前記フィン１１の数はそれほど多くなくて良く、また、
その長さも短くて良い。A large number of fins 11 for heat exchange are protruded from the inner peripheral surface of the first cylinder 1. Since the cooling water W flows through the first passage 12 in the first cylinder 1, the heat transfer coefficient is excellent, so that
The number of the fins 11 does not need to be so large, and
Its length is also short.

The combustion gas inlet side of the second cylinder 2 (same direction as the cooling water inlet side of the first cylinder 1) is connected to the intake passage 9 of the engine E using a pipe 23, and this pipe 23
A combustion burner 24 is installed therein, and the combustion gas outlet side is connected to the inlet of the intake manifold 8 of the engine E via a switching valve 7 using a pipe 25. This switching valve 7 is operated by an actuator 6 and connects either the pipe line 25 or the intake passage 9 to the exhaust manifold 8.

いる。The temperature sensor 14, the actuator 6, and the combustion burner 24 are connected to a control device 40, and the control device 40 moves the switching valve 7 via the actuator 6, so that the temperature detected from the temperature sensor 14 is set to a set value. If the temperature is lower than the set value, the intake manifold 8 is connected to the second passage 22 via the pipe 25, and if the temperature detected by the temperature sensor 14 is equal to or higher than the set value, the intake manifold 8 is connected to the second passage 22 via the pipe 25. It is designed to be connected to 9. Then, only when the intake manifold 8 is connected to the second passage 22, the combustion burner 24 is ignited by the control device 40, and hot combustion gas flows into the second passage 22.

ガスとなって第２通路２２内に流入する。In the vehicle heating heat exchanger of the present invention configured as described above, when the engine E is started from a cold state, the low temperature detected value of the cooling water from the temperature sensor 14 is detected by the control device 40.
is input, the control device 40 sets the switching valve 7 to the position indicated by the solid line, connects the intake manifold 8 to the second passage 22, and at the same time, the combustion burner 24 is ignited. Then, the intake air introduced into the engine E is combusted by the combustion burner and flows into the second passage 22 as a high-temperature gas.

を介して第３通路３２内にある暖房用空気を加熱する。This high temperature combustion gas is transferred to the first cylinder 1 and the second cylinder 2 of the heat exchanger.
It passes through a second passage 22 surrounded by fins 21 and heats the first cylinder 1 and the second cylinder 2. The first cylinder 1 and second cylinder 2, which have high thermal conductivity, become high in temperature in a short time due to this combustion gas, and this heat is transferred to the fins 31 and the lattice partition wall 33.
The heating air in the third passage 32 is heated through the heating air.

てエンジンの始動性を高める。Therefore, at this time, if the driver of the car turns on the heater switch inside the car, heating air is blown into the third passage 32 by the ventilation fan 35, and this air is heated in the third passage 32 and becomes warm air. , warm air is immediately introduced into the car. Furthermore, the combustion gas then flows into the engine to improve the startability of the engine.

の発生も減るという効果がある。In this way, warm air for indoor heating can be obtained by the vehicle heating heat exchanger of the present invention immediately after the engine is started.
Even if the vehicle is operated immediately after a cold start, warm air is supplied to the driver, which improves the comfort of driving during cold seasons or in cold regions, which in turn leads to safer driving and reduces the risk of accidents. It has the effect of reducing

４の作動を停止させる。When the coolant temperature of the engine E rises, the temperature sensor 14 detects this and inputs the signal to the control device 40, so the control device 40 detects when the detected value from the temperature sensor 14 exceeds the set value. At this point, the actuator 6 switches the switching valve 7 to the position shown by the broken line, connecting the intake manifold 8 to the intake passage 9 and connecting the combustion burner 2 in the pipe line 23.
Stop the operation of 4.

用空気は加熱されるので、室内暖房用の空気温度が低下
することがない。As a result, high-temperature combustion gas no longer passes through the second passage 22, but the first passage 1, which is at a high temperature at this point,
Since the heating air flowing in the third passage 32 is heated by the cooling water W in the third passage 32, the indoor heating air temperature does not drop.
