Abstract: A heat exchange plate for a plate-type heat exchanger and a plate-type heat exchanger provided with said heat exchange plate. The heat exchange plate comprises: an opening (11) used to form an end opening; a plurality of protrusions (12) arranged around at least a portion of the opening (11) along a circular line along the opening (11), the plurality of protrusions (12) protruding towards one side of a plate plane (15); transition portions (16) arranged between at least two neighbouring protrusions (12), the transition portions (16) being located on one side of the plate plane (15), and being a preset distance from the plate plane (15). The distance from the tops of the protrusions (12) to the plate plane is greater than the distance from the lowest points of the transition portions (16) to the plate plane. The present heat exchange plate and plate-type heat exchanger are provided with a relatively small end opening, can obtain a better fluid distribution between heat exchange fluid channels, and can obtain a better fluid distribution between heat exchange fluid channels even if a carbon dioxide refrigerant is used.

Abstract: Provided are a reinforcer (30) used for a plate heat exchanger (100) and a plate heat exchanger (100), the reinforcer (30) being used to reinforce an area around an opening (13) of at least one heat exchange plate (10). The plate heat exchanger (100) comprises multiple heat exchange plates (10); a heat exchange space formed between adjacent heat exchange plates (10) of the multiple heat exchange plates (10); a heat exchange channel (11) formed between the heat exchange plates (10), wherein the heat exchange channel (11) is used for a heat exchange medium to flow into or out of the plate heat exchanger (100), and is constituted by openings (13) in the multiple heat exchange plates (10); and a reinforcer (30), used to reinforce an area around an opening (13) in at least one heat exchange plate (10). The plate heat exchanger (100) can alleviate or prevent deformation or cracking of a backing plate (18) and a heat exchange plate (10) of the plate heat exchanger (100), especially the two heat exchange plates (10) adjacent to the backing plate (18), in the area around the heat exchange channel (11).
