Abstract

Heat exchangers gained wide acceptance in aviation and energetics in heat supply systems. The coupling between the pipes and the pipe grid is one of the critical places in the heat exchanger. Conventional technologies of this coupling (flaring, welding, soldering) are complex, costly and time-consuming. This article presents the study and implementation of the possibility of applying an electric-explosive pulse for this kind of coupling. The authors considered the main stages of the said technology such as of an electric-explosive cartridge manufacturing, the product and test installation preparing, conducting an experiment and quality checking of the coupling. The results of the study revealed that application of the electric-explosive impulse meets the level of conventional coupling methods, whereas the cost of materials and time is by far less.

Keywords:

heat exchanger, pipe, pipe grate, pulse pressure source, electric explosive cartridge
