a frame disposed between a first heat exchanger and a second heat exchanger and defining an inner space through which air introduced from a grill opening of a vehicle flows in an airflow direction, each of the first heat exchanger and the second heat exchanger having a core in which heat exchange is performed and a remaining portion other than the core;
an opening-closing portion configured to selectively open and close the inner space of the frame; and
a protrusion protruding, in a direction parallel to the airflow direction, from the frame toward the remaining portion of at least one of the first heat exchanger or the second heat exchanger, wherein
the first heat exchanger is located upstream of the second heat exchanger in the airflow direction,
the protrusion includes:
a first protrusion protruding from the frame toward the second heat exchanger; and
a second protrusion protruding from the frame toward the first heat exchanger,
the first protrusion is in contact with the second heat exchanger and the second protrusion is in contact with the first heat exchanger,
the core is formed by a plurality of tubes that are stacked with each other in a tube stacking direction,
each of the first heat exchanger and the second heat exchanger includes a side plate disposed at an end of the core in the tube stacking direction to reinforce the core,
the first protrusion is in contact with the side plate of the second heat exchanger, and
