In accordance with the present invention, provided is a flow path structure of a hybrid heat exchanger. The flow path structure includes: a first pass part formed by stacking a plurality of plate-shaped heat exchange plates, wherein a first coolant flow path for the flow of high-temperature coolant and a first refrigerant flow path for the flow of a refrigerant are formed, and the high-temperature coolant and the refrigerant, flowing in the first coolant flow path and the first refrigerant flow path respectively, selectively exchange heat with each other; a second pass part provided on a lower side of the first pass part, and formed by stacking the plurality of plate-shaped heat exchange plates, wherein a second coolant flow path for the flow of low-temperature coolant and a second refrigerant flow path for the flow of a refrigerant are formed, and the low-temperature coolant and the refrigerant, flowing in the second coolant flow path and the second refrigerant flow path respectively, selectively exchange heat with each other; a first refrigerant discharge pipe formed on an upper side of the first pass part while connected with the first refrigerant flow path to selectively discharge the refrigerant; and a second refrigerant discharge pipe formed on a lower side of the second pass part while connected with the second refrigerant flow path to selectively discharge the refrigerant. Therefore, the flow path structure of a hybrid heat exchanger is capable of reducing the passage resistance of a refrigerant becoming larger in specific volume during a heating operation.
