Cylindrical heat exchanger with high heat exchange efficiency

Abstract

The invention relates to a cylindrical heat exchanger with high heat exchange efficiency. The cylindrical heat exchanger with high heat exchange efficiency comprises a shell, a heat exchange coil anda heat insulation plate piece, wherein the shell comprises a circular body part with upper and lower openings, a circular base part and a circular end cover part; a combustor installing hole, a seat toroidal clamping groove and a water outlet port stretching hole are formed in the base part; the end cover part comprises a smoke outlet hole located in the center, an end toroidal clamping groove surrounding the smoke outlet hole, and a water inlet port stretching hole; the heat exchange coil is formed by spirally winding a pipe body into a cylinder shape; the heat insulation plate piece is arranged in the heat exchange coil; a combustion cavity is arranged at one end of the heat insulation plate piece; a smoke outlet cavity is arranged at the other end of the heat insulation plate piece; andthe water outlet end of the heat exchange coil is arranged in the seat toroidal clamping groove. The cylindrical heat exchanger with high heat exchange efficiency further comprises an inner flow guiding sleeve, wherein the inner flow guiding sleeve is located in the shell and surrounds the heat exchange coil; and a flow guiding clearance is arranged between the inner flow guiding sleeve and the heat exchange coil. By arranging the inner flow guiding sleeve, heat energy is guided into the heat exchange coil pipe, so that a heat insulation effect is achieved, the temperature rise of the shell is reduced, and the heat exchange efficiency is improved.
