Abstract: A heat exchange assembly (1) for a heat exchanger, a heat exchanger comprising the heat exchange assembly (1), and a mold forming the heat exchange assembly (1) are provided. The heat exchange assembly (1) comprises: multiple heat exchange tubes (11) through which a heat exchange medium flows; a connecting plate (12) connected between adjacent heat exchange tubes (11); and a heat exchange plate (121) formed by at least one part of the connecting plate (12). The mold comprises: a first mold, the first mold forming holes (110) in the multiple heat exchange tubes (11); and a second mold (2), the second mold having a mold cavity (20) forming a main body of the heat exchange assembly (1), the mold cavity (20) having an opening (21), the heat exchange assembly (1) being extruded from the opening (21) of the mold cavity (20) of the second mold (2), and the opening (21) being strip-shaped and extending along a curved line.

Abstract: An un-finned heat exchanger (100). The heat exchanger (100) comprises: a heat exchange tube (1), which comprises a body; a fluid channel (11) formed inside the body; and a collecting tube (2) connected to the heat exchange tube (1). Using the heat exchanger can reduce accumulation of dirt on the heat exchanger.

Abstract: A heat exchanger (100), a heat exchanger module (100?) having the heat exchanger (100), and an air conditioning system having the heat exchanger (100) or the heat exchanger module (100?); the heat exchanger (100) comprises: a first header (11) and a second header (12), with an axis of the first header (11) being inclined relative to an axis of the second header (12); and a heat exchange pipe (2) connected to the first header (11) and the second header (12), the heat exchange pipe (2) being bent. The heat exchange efficiency can be increased by using the heat exchanger (100).

Abstract: A heat exchanger (10) comprises: a first sub-heat exchanger (100), which has a first manifold (110), a second manifold (120), and at least two heat exchange tubes (130); and a second sub-heat exchanger (200), which has a third manifold (210), a fourth manifold (220), and at least one heat exchange tube (230), at least one of the heat exchange tubes (130) in the first sub-heat exchanger (100) being part of a flow path of the second sub-heat exchanger (200).

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).
