The invention relates to heat exchanger and anodic protection anti-corrosion technologies, in particular to an anodic protection evaporation type acid cooler mainly used for concentrated sulphuric acid cooling. An arranged heat exchange plate bundle (4) consists of a plurality of metal cavity plate tubes. A water spraying distributor (3) is arranged above the heat exchange plate bundle (4). A water tank (6) and a water pump (5) are arranged below the heat exchange plate bundle (4). An air blower (1) is arranged above the water spraying distributor (3). An air inlet is formed between the water tank and the heat exchange plate bundle. The plurality of cavity plate tubes form a passage for high-temperature sulphuric acids to pass through. Passages for air and sprayed water are formed between every two adjacent cavity plate tubes. Cooling water is sprayed on the heat exchange plate bundle, and performs heat transfer and mass transfer with the air to carry heat away in an evaporation way to further realize cooling
