The invention discloses a heat exchanger and a motor vehicle air conditioning system, and belongs to the technical field of heat exchange equipment, the heat exchanger comprises a shell, the shell comprises a side plate assembly and a first cover plate assembly, a heat exchange cavity is defined by the side plate assembly, the side plate assembly comprises a first side plate, and the end of the first side plate protrudes from inside to outside to form a convex hull; a first inlet allowing first fluid to flow in is formed in the convex hull, and the first cover plate assembly covers a port of the heat exchange cavity; the spoiler is arranged between the convex hull and the heat exchange cavity, a retention cavity capable of retaining the first fluid is defined by the spoiler, the convex hull and the first cover plate assembly, and a circulating opening is formed in the position, close to the first cover plate assembly, of the spoiler so that the first fluid can flow into the heat exchange cavity through the retention cavity. The spoiler is additionally arranged in the shell, when the first fluid flows in, the first fluid is spoiled by the spoiler, is retained in the retention cavity and then flows into the heat exchange cavity through the circulation opening, the entering flow is reduced, the flow speed is reduced, the space utilization rate of the heat exchange cavity is increased, heat exchange is more sufficient, and the heat exchange effect is improved.

    本发明公开了一种换热器及机动车空调系统,属于换热设备技术领域,换热器,换热器包括:壳体,壳体包括侧板组件和第一盖板组件,侧板组件围成换热腔,侧板组件包括第一侧板,第一侧板的端部由内向外凸起形成凸包,凸包处设有供第一流体流入的第一入口,第一盖板组件盖设在换热腔的端口处;阻流板,设在凸包与换热腔之间,并与凸包、第一盖板组件围成能够留滞第一流体的留滞腔,且阻流板靠近第一盖板组件处设有流通口,以供第一流体经留滞腔流入换热腔中。在壳体中另设阻流板,第一流体流入时,被阻流板阻流,滞留在留滞腔中,再通过流通口流入换热腔中,减小进入的流量,并降低流速,提高了换热腔的空间利用率,换热更充分,提升换热效果。
