FIELD: chemical industry; production of the heat exchangers for the isothermal chemical reactors. ^ SUBSTANCE: the invention is pertaining to the chemical industry, in particular, to the heat exchangers for the isothermal chemical reactors and presents the block heat exchanger for the radial or radial-axial isothermal reactors and has essentially the annular and cylindrical structure with the axial through hole of the definite diameter and consists of the set of the essentially rectangular solid box-shaped heat exchangers located in several having the common axis concentric areas and forming in the block-shaped heat exchanger the set of the essentially radial groups consisting of the heat exchangers laying in one radial plane and in the different annular zones, the long sides of which are passing in parallel to the axis of the block heat exchanger, and their short sides are passing in the radial direction, and each such heat exchanger has the internal cavity, through which the running coolant is passing; at least one located on one side of the heat exchanger pipe for distribution of the fed in it running coolant and at least one located on the opposite side of the heat exchanger pipe, In which the running coolant having passed through the heat exchanger is collected. The indicated pipes are connected on the one side to the heat exchanger internal cavity at least through one hole present in them, and on the other side - with the branch-pipes located outside for feeding in the heat exchanger and for withdrawal from it of the running coolant. The technical result of the invention is provision of the flow of the running coolant in the radial direction side by side with the axial direction. ^ EFFECT: the invention ensures the flow of the running coolant in the radial direction side by side with the axial direction. ^ 22 cl, 10 dwg
