Claims17
A heat exchanger of an exhaust heat recovery apparatus comprising:
- a housing extending in one direction, with both sides thereof being opened to allow exhaust gas to be introduced from one side thereof and discharged to the other side thereof;
- at least two tube parts spaced apart from each other at a predetermined distance in a height direction while being accommodated inside the housing to form a flow path in a direction in which the housing extends to allow the exhaust gas introduced from the one side of the housing to pass therethrough;
- an exhaust gas inlet formed in a lower portion of the one side of the housing;
- an exhaust gas outlet formed in a lower portion of the other side of the housing and having a smaller area than the exhaust gas inlet;
- a coolant inlet formed in a side surface of the housing to introduce coolant between the tube parts;
- and
- a coolant outlet formed in the side surface of the housing to discharge the coolant introduced between the tube parts,
- wherein one end of the exhaust gas inlet is opened and the exhaust gas outlet has an end portion formed at the other side thereof to be closed.
