Abstract
According to the present invention, a heat exchanger comprises a plurality of coolant tubes; a plurality of fins contacting the plurality of coolant tubes, wherein each of the plurality of fins comprises: a plurality of fin parts spaced apart from each other; an upper fin part connecting part connecting respective upper portions of the plurality of fin parts with each other, the upper fin part connecting part contacting one of the plurality of coolant tubes; a lower fin part connecting part connecting respective lower portions of the plurality of fin parts with each other, the lower fin part connecting part contacting another one of the plurality of coolant tubes; an upper opening formed at an upper portion of each of the plurality of fin parts; a lower opening formed at a lower portion of each of the plurality of fin parts; an upper protrusion protruded from an upper portion of each of the plurality of fin parts, the upper protrusion contacting the first coolant tube; and a lower protrusion protruded from a lower portion of each of the plurality of fin parts, the lower protrusion contacting the second coolant tube. Accordingly, the present invention provides increased productivity…
