Abstract

The invention relates to a fixed tube-sheet heat exchanger with grooved parent tube surfaces, which particularly consists of heat exchange tubes, wherein the inner surface of the heat exchange tube is provided with a sintered layer, and the outer surface of the heat exchange tube is uniformly grooved both radially and axially. The fixed tube-sheet heat exchanger comprises a shell, wherein the left end of the shell is provided with a left channel box, and the right end of the shell is provided with a right channel box; the upper top of one end, adjacent to the left channel box, of the shell is provided with a thermal fluid inlet, and the lower bottom, adjacent to the right channel box, of the shell is provided with a thermal fluid outlet; the upper top of the left channel box is provided with a cold fluid inlet, and the lower bottom of the right channel box is provided with a cold fluid outlet; the heat exchange tubes distributed along the axial length of the shell are arranged in the shell, and each heat exchange tube comprises a parent tube; a porous layer is arranged on the inner peripheral surface of the parent tube, and a grooved layer is arranged on the outer peripheral surface of the parent tube; and the grooved layer comprises a plurality of grooves uniformly distributed along the axial direction and the circumferential direction of the parent tube. The fixed tube-sheet heat exchanger has a simple and compact structure, can improve the heat transfer efficiency of the heat exchanger, reduces the running energy consumption and equipment investment of the heat exchanger, and is safe and reliable.

Description

technical field [0001] The invention relates to a heat exchanger, especially a fixed tube-sheet heat exchanger with grooves on the surface of the base tube, specifically a sintered layer on the inner surface and uniform radial and axial openings on the outer surface. The fixed tube-sheet heat exchanger with grooves on the surface of the base tube composed of grooved heat exchange tubes is used for shell-and-tube heat exchangers with phase change boiling heat transfer used in petroleum, chemical, metallurgical and thermal energy engineering. The utility model relates to a C-type fixed tube-sheet heat exchanger, which belongs to the technical field of heat exchangers. Background technique [0002] Heat exchangers are widely used in chemical, fertilizer, oil refining, power, construction, food and other industrial sectors, among which shell-and-tube heat exchangers dominate many types of heat exchanger products. This type of heat exchanger tube bundle usually adopts smooth tub...
