The utility model relates to the field of machinary, concretely relates to graphite heat exchanger. Graphite hole piece heat exchanger that downthehole wall is reinforceed, including massive graphite block, it has plural number strip interconnection and plural number strip longitudinal channel to open in the graphite block, and interconnection, longitudinal channel's both ends all are equipped with the hole, and interconnection, longitudinal channel's inner wall facing covers and has one deck basalt fiber layer, be equipped with the equidistant strip recess of arranging of complex root on the inner wall of interconnection, basalt fiber layer thickness everywhere equals, basalt fiber layer surface coating has one deck graphite alkene coating, and the strip recess is filled up to graphite alkene coating. The basalt fiber layer has great intensity, and the low shortcoming of graphite material compressive strength has been overcome on the basalt fiber layer of establishing in the graphite block passageway, makes
