The invention discloses a heat exchanger and an air conditioning system, and relates to the technical field of heat exchange. The heat exchanger comprises: a first heat exchange assembly, provided with a refrigerant inlet and comprising multiple columns of first heat exchange pipes arranged in rows; and a second heat exchange assembly, provided with a refrigerant outlet, fixed and communicated with the first heat exchange assembly, and comprising multiple columns of second heat exchange pipes arranged in rows, wherein the hydraulic diameter of the second heat exchange pipes is smaller than that of the first heat exchange pipes. On the whole, compared with the prior art, the hydraulic diameter of the second heat exchange pipes is smaller than that of the first heat exchange pipes, so that the heat exchange pipes are matched with the phase change of a refrigerant medium, the heat exchange sufficiency and the heat exchange efficiency are improved, and meanwhile, the pressure loss of the refrigerant medium is also reduced.

    本发明公开了一种换热器及空调系统,涉及换热技术领域。该换热器包括第一换热组件,设有冷媒入口,第一换热组件包含多列成排设置的第一换热管;第二换热组件,设有冷媒出口,第二换热组件与第一换热组件固定并连通,第二换热组件包含多列成排设置的第二换热管,第二换热管的水力直径小于第一换热管的水力直径。整体而言,本发明相较于现有技术,通过设置第二换热管的水力直径小于第一换热管的水力直径,使换热管与冷媒介质的物相变化相匹配,提高了换热充分性、换热效率,同时也降低了冷媒介质的压力损失。
