A heat exchange element is a heat exchange element formed by stacking a plurality of heat transfer plates. The heat transfer plate includes: a heat exchanger that allows air passing through one side in a stacking direction of a plurality of the heat transfer plates and air passing through another side in the stacking direction to pass through in directions facing to each other to cause heat exchange; a header provided on one side and another side with the heat exchanger interposed therebetween when viewed along the stacking direction; and a joining edge provided along a side of the heat exchanger not in contact with the header. Joining edges of a plurality of the stacked heat transfer plates are in contact with each other and joined by ultrasonic welding, and the joining edge is formed with a first convex portion that protrudes along the stacking direction.

The heat exchanger tray provided herein may include a base, a cover, and a heat exchange coil. The base may include a cutout and a bottom portion with one or more sidewalls forming a serpentine path for wastewater. The cover may be positioned within the cutout of the base to create a space between the base and the cover. The cover may include one or more protruding portions that engage with the one or more sidewalls of the bottom portion of the base to enclose the serpentine path. The heat exchange coil may be positioned in and along at least a portion of the serpentine path between the base and the cover. Fresh water may flow through the heat exchange coil. Wastewater may flow through the serpentine path between the base and the cover, such that the wastewater may heat the fresh water flowing through the heat exchange coil.

The present invention is to resolve a problem such as the above, the purpose being providing a heat exchanger capable of improving heat exchange efficiency by allowing the amount of heating medium flowing through heat medium channels, which are in multiple layers between a plurality of plates, to be evenly distributed. The present invention comprises: heating medium channels, in the space in between a pair of plates facing each other, through which the heating medium flows; combustion gas channels, on the outer sides of the heating medium channels, through which combustion gas burned in a burner flows; and heating medium dispersion parts, having an opening part and a shutting part, on an inlet, through which the heating medium flows into the heating medium channel, and an outlet, through which the heating medium flows out from the heating medium channel.

The purpose of the present invention is to provide a heat exchanger which minimizes pressure drops of the heating medium by allowing smooth circulation of same along the heating medium channels formed between plates, improves the efficiency of heat exchange by preventing localized overheating, and which additionally facilitates the production of the heat exchanger. The present invention comprises a heat exchange part having heating medium channels, through which heating medium flows, and combustion gas channels, through which combustion gas burned in a burner flows, adjacently disposed in alternation in the spaces between the plurality of plates, wherein the heat exchange part surrounds the outer sides of a central combustion chamber space, a plurality of the heat exchange parts are provided in a stacked structure, and the flow direction of the heating medium is unidirectional only in a part of the heating medium channels from among the heating medium channels provided in each layer.
