Abstract

The invention relates to a heat exchanger module (100) for a refrigerant circuit, comprising a refrigerant accumulator (102) with an accumulator bottle (104) and a heat exchanger (106), wherein the heat exchanger includes a stack of plates (108) consisting of at least two heat exchanger plates (110). The heat exchanger plates (110) of the heat exchanger (106) are formed with a basic shape that deviates from a rectangle, and the heat exchanger plates (110) surround the accumulator bottle (104) at least partially. The invention further relates to a cooling system and vehicle with such a heat exchanger module (100).
