HEAT EXCHANGING ASSEMBLY

A heat exchanging assembly (100), comprising a heat exchanger core body (1). The heat exchanger core body (1) comprises a plurality of first-type plates (1141) and a plurality of second-type plates (1142) that are stacked; each first-type plate (1141) has a first orifice (1141a), a second orifice (1141b), and a third orifice (1141c); each second-type plate (1142) has a first orifice (1142a) and a second orifice (1142b); along the length or width direction of the heat exchange core body (1), the third orifice (1141c) is located between the first orifice (1141a) and the second orifice (1141b); a first flow channel (12) has a first partial fluid path (121), a second partial fluid path (123), a third partial fluid path (1224), and an inter-plate path (122); the first partial fluid path (121) is formed at the first orifice (1141a); the second partial fluid path (123) is formed at the second orifice (1141b); the third orifices (1141c) are aligned to form the third partial fluid path (1224); and the inter-plate path (122) is communicated with the first partial fluid path (121), the second partial fluid path (123), and the third partial fluid path (1224). The heat exchanging assembly (100) is small in structure.
