Abstract: Disclosed are a header assembly (100) for a heat exchanger and a heat exchanger having the header assembly (100). The header assembly (100) includes: an outer tube (1), the outer tube (1) having a tube wall (11); an inner tube (2), the inner tube (2) being provided in the outer tube (1) and having a tube wall (21) and a through hole (22) penetrating through the tube wall (21) of the inner tube (2), and a cavity (30) being formed between the outer tube (1) and the inner tube (2); and an opening (12) formed in the tube wall (11) a of the outer tube (1) and used for communicating the cavity (30) between the outer tube (1) and the inner tube (2) with a heat exchange g tube. The header assembly (100) and the heat exchanger having the header assembly (100) can improve heat exchange efficiency.

Abstract: Disclosed is a multi-loop plate heat exchanger, including: a plurality of heat exchange plates arranged in a stacked manner; heat exchange channels formed between adjacent heat exchange plates in the plurality of heat exchange plates; and port channels extending through the heat exchange plates and respectively used for inflow and outflow of a heat exchange medium, at least one of the port channels including at least two fluid channels which are separated from each other and used for inflow or outflow of at least two of multiple loops of refrigerant. The at least two fluid channels share one of the port channels, and the at least two fluid channels are arranged side by side in the radial direction of the port channel.
