The invention relates to cooling equipment. The cooling equipment comprises an upper sealing head, a shell body and a lower sealing head, wherein the upper sealing head is located at the upper part of the shell body and an observation hole and a material inlet are formed in the upper sealing head; an upper pipe plate is arranged between the upper sealing head and the shell body; the lower sealing head is located at the lower part of the shell body; a maintenance hole and a material outlet are formed in the lower sealing head; a lower pipe plate is arranged between the lower sealing head and the shell body; a heat exchange pipe is arranged between the upper pipe plate and the lower pipe plate; the shell body is internally provided with a cooling water inlet and a cooling water outlet; the heat exchange pipe is a phenolic resin pressing type graphite pipe; the heat exchange pipe is in elastic sealed connection with the upper pipe plate through a sealing ring; and the heat exchange pipe is in elastic sealed connection with the upper pipe plate through a sealing ring. According to the cooling equipment provided by the invention, elastic connection is realized through adopting rubber rings, so that strength of carbon steel and advantages including corrosion resistance, good heat exchange effect and the like of a graphite material are perfectly combined.
