The invention discloses a heat exchange plate and a heat exchanger, relates to the technical field of heat exchange devices, and aims to avoid the phenomena of large pressure drop and reduced heat exchange temperature difference of phase change fluid and improve the heat exchange performance of the heat exchanger. A first partition and a second partition are arranged on the heat exchange plate. A plurality of first heat exchange units are arranged in the first partition, a plurality of first protruding parts are arranged on the top face of each first heat exchange unit, and a first concave part is defined by the first protruding parts. A plurality of second heat exchange units are arranged in the second subarea, a plurality of second protruding parts are arranged on the top face of each second heat exchange unit, and a second concave part is defined by the second protruding parts. And the volume of a heat exchange cavity formed on the top surface of the first subarea on the heat exchange plate is greater than
