The invention discloses a countercurrent tube bundle type wall-type heat exchanger, which is formed by connecting 1 to 50 heat exchange units in series; and 1 to 65 rows of total 2 to 200 hot fluid tubes and cold fluid tubes which are opposite in flow directions and alternately arranged parallelly are arranged in each heat exchange unit; the hot fluid tubes and the cold fluid tubes are filled with flow around bodies; a heat insulating gasket is arranged between two heat exchange units and a connecting part of the two heat exchange units; and heat exchange units at the head and at the tail arerespectively communicated with cold and hot fluid splitter / mergers arranged at two ends. The countercurrent tube bundle type wall-type heat exchanger has the advantages of strong heat exchange capacity, high structural strength, compact equipment, small occupied space, low operating cost, obvious energy-saving potential, and convenient disassembly, cleaning and maintenance, and can be widely applied to industrial processes such as heating, cooling, condensing and evaporating in industrial departments such as chemical engineering, petroleum, foodstuff, metallurgy, machinery, light industry, electric power, shipping, papermaking, mines, medicaments, and concentrated heat supply.
