1. A plate-type heat exchanger comprising:
a plurality of stacked main plates each comprising a center flat plate having a fluid flowing structure including a through hole formed in the center flat plate, and a lateral blade formed by bending an edge of the center flat plate in one direction; and
a reinforcing plate interposed between a bracket plate fixed to an external device and at least one of the plurality of stacked main plates connected to the bracket plate,
wherein the reinforcing plate and the bracket plate are at least partially in surface contact with each other,
wherein the reinforcing plate is in surface contact with the entire center flat plate of one of the plurality of stacked main plates and is in surface contact with at least a part of the lateral blade,
wherein when one or more of the lateral blades of the plurality of stacked main plates overlap one another to define a multilayer and the remaining lateral blades of the remaining plurality of stacked main plates, which do not overlap one another, define a single layer as a heat exchanger core formed by stacking the plurality of stacked main plates so that the plurality of stacked main plates overlaps one another, the reinforcing plate is in surface contact with the lateral blade in a region including a single-layer forming region of the lateral blade in which the single layer is formed,
wherein the bracket plate comprises:
a fixing plate portion comprising a plate surface portion provided to be in surface contact with one surface of the heat exchanger core, and a peripheral portion bent from an edge of the plate surface portion and configured to surround a part of a periphery of the heat exchanger core; and
a connection plate portion integrated with the fixing plate portion and bent in a direction different from that of the peripheral portion in a region except for a region in which the peripheral portion is formed, the connection plate portion being connected to the external device, and
wherein the reinforcing plate is in surface contact with at least a part of the lateral blade in a region in which the connection plate portion is formed.
