ENSURING THERMAL REGIME FOR THE SUPPLY DISTRIBUTED DEVICES IN THE COMPOSITION OF THE SHIP'S SECONDARY POWER SUPPLY SYSTEMS ON THE BASE OF THE STANDARDIZED UNITS

Abstract

Aim. The article deals with the problem of constructing the power supply devices in the composition of the ship's secondary power systems based on standardized blocks and securing their thermal regime.Methods. It is stated that with the advent of modern power electronics multifunctional components the secondary power supply developers got possibilities to improve the quality of secondary power supply and to upgrade the existing systems.Results. The advantages of unified power units, having a function of parallel operation are revealed. Heat transfer processes in a vertical channel with free convection, and the calculation of the minimum width of the channel, which provides efficient heat removal have been analyzed.Conclusion.A model is proposed for determining the minimum distance between the blocks without deterioration of heat transfer in the channel formed by the walls of adjacent blocks.
