Abstract

The invention discloses a manufacturing method for a C-shaped shell-cladding-free type heat exchanger, and relates to a manufacturing method for a heat exchanger. In order to solve the problems that an existing heat exchanger assembly method is great in operation difficulty and is low in working efficiency while heat exchange tubes penetrate into tube holes by adopting a method of enabling a fixedtube plate to sequentially penetrate through the heat exchange tubes, the invention provides a mounting method comprising the following steps: step I, arranging the heat exchange tubes one by one; step II, arranging the tube plate in a sleeving mode; step III, fixedly connecting the two ends of the tube plate to corresponding supporting devices; step IV, welding and expanding the end part of eachupper single tube body and the end part of each lower single tube body with corresponding tube holes of the tube plate; and step V, lifting and turning over a heat exchanger assembly formed in the steps to other positions to perform other processes. The invention belongs to the manufacturing field of heat exchangers.

Description

technical field [0001] The invention relates to a method for manufacturing a heat exchanger, in particular to a method for manufacturing a C-type casing-less wrapping heat exchanger, which belongs to the field of heat exchanger manufacturing. Background technique [0002] A heat exchanger is an energy-saving device that transfers heat between materials between two or more fluids at different temperatures. It transfers heat from a fluid with a higher temperature to a fluid with a lower temperature, so that the fluid temperature reaches the process The specified index is to meet the needs of the process conditions, and it is also one of the main equipment to improve energy utilization. In the product and manufacturing process of nuclear power, thermal power and petrochemical container heat exchangers, the assembly process of tube sheets and heat exchange tubes is the key difficulty in manufacturing. After the position is fixed, the heat exchange tubes are inserted sequentiall...
