The invention discloses a liquid heavy metal pipe shell type heat exchanger. The liquid heavy metal pipe shell type heat exchanger comprises a barrel, an upper seal head, a lower seal head, a plurality of heat exchange pipes arranged in the barrel, and a pipe plate which is in sealed connection between the barrel and the lower seal head, wherein the upper seal head and the lower seal head are in sealed connection to the upper end and the lower end of the barrel correspondingly. The side wall of the barrel is provided with a shell pass inlet and a shell pass outlet which are used for liquid heavy metal inflow and outflow. A partition plate is in sealed connection between the pipe plate and the lower seal head, and an inlet cavity and an outlet cavity are formed in the two sides of the partition plate correspondingly. The pipe plate is provided with a plurality of first through holes communicating with the inlet cavity and a plurality of second through holes communicating with the outletcavity. The inlet ends of the multiple heat exchange pipes are in sealed connection to the corresponding multiple first through hole positions and communicate with the inlet cavity. The outlet ends of the multiple heat exchange pipes are in sealed connection to the corresponding multiple second through hole positions and communicate with the outlet cavity. The lower seal head is provided with a pipe pass inlet communicating with the inlet cavity and a pipe pass outlet communicating with the outlet cavity. The liquid heavy metal pipe shell type heat exchanger is simple and compact in structure, stable and firm.
