Title:
PLATE HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2024/060347
Kind Code:
A1
Abstract:
A plate heat exchanger, comprising a plurality of heat exchange plates (3) which are stacked between a front clamping plate (1) and a rear clamping plate (2). A distribution plate (4) is arranged in a refrigerant feeding channel (103) along the channel direction; the distribution plate (4) divides the refrigerant feeding channel (103) into a first chamber (103a) and a second chamber (103b); the first chamber (103a) and the second chamber (103b) are communicated by means of through holes (41) on the distribution plate (4); a refrigerant inlet (101) and a refrigerant outlet (102), and a secondary refrigerant inlet (201) and a secondary refrigerant outlet (202) in each heat exchange plate (3) each are oppositely arranged on diagonal positions of a plate body (30); a heat exchange texture is constructed in the middle of the plate body (30); in addition to a plurality of transverse ribs (32), the heat exchange texture further comprises a plurality of vertical ribs (33) constructed between every two adjacent transverse ribs (32). By using the structure, fluids in the plate heat exchanger are uniformly distributed, and the heat exchange efficiency is higher.
