Patent ID: 10823514

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).
