The invention relates to the technical field of waste heat recovery, and discloses a waste heat recovery heat exchanger and an automobile air conditioner. The waste heat recovery heat exchanger comprises an upper cover plate, heat exchange plate groups and a lower bottom plate which are sequentially stacked, wherein a first liquid inlet, a first liquid outlet, a second liquid inlet and a second liquid outlet are formed in the upper cover plate, the number of the heat exchange plate groups is at least one, first liquid channels are respectively formed between the heat exchange plate groups, between the heat exchange plate group and the upper cover plate and between the heat exchange plate group and the lower bottom plate, the first liquid channel is respectively communicated with the firstliquid inlet and the first liquid outlet, each heat exchange plate group comprises two heat exchange plates, the two heat exchange plates form a second liquid channel, the second liquid channel is isolated from the first liquid channel, and the second liquid channel is respectively communicated with the second liquid inlet and the second liquid outlet. The waste heat recovery heat exchanger disclosed by the invention is compact in structure, small in size, convenient to install and high in heat exchange efficiency, and the heating capacity of the automobile air conditioner running under a low-temperature condition is enhanced.
