<p>The present invention relates to a plate-type heat exchanger and, more specifically, to a plate-type capable of preventing the deformation of a heating plate supported around through-holes by a frame by forming a gap-shaped penetration channel connecting the through-holes on flow passage forming plates overlapped on both sides of the heating plate and inner flow passages of the frame. In the plate-type heat exchanger including the multiple plate-shaped flow passage forming plates surrounded by the frame formed on the sides and the plate-shaped heating plates interposed between the flow passage forming plates and stacked with the multiple flow passage forming plates by turns to form a flow passage inside the frame by being closely adhering the sides of the heating plates to the frame of the flow passage forming plates, the plate-type heat exchanger according to the present invention includes at least one through-hole on the frame of the flow passage forming plates and through-holes connected to the through-holes of the flow passage forming plates on both sides of the heating plate. The present invention is characterized by including the gap-shaped penetration channel to connect some or all of the through-holes and the flow passage formed inside the frame in the frame of the flow passage the forming plate.</p> |
