RU95104992A - Induction heater of liquids - Google Patents

Abstract

FIELD: electric engineering. SUBSTANCE: device has housing 14, transformer, which is located in housing and has multiple-rod ferromagnetic core 1 and multiple- phase primary winding 2, which is connected to alternating current power supply. In addition device has secondary winding which serves for heat exchange and is designed as hollow chamber 4 with lower inlet 5 and upper outlet 6 for transmission of fluid to be heated. Chamber 4 has through vertical channels 7 with electric- current conducting walls 8. Rods of transformer core 1 are located in channels with space. Device may be used for electric heating of houses and hot-water supply. EFFECT: increased efficiency, decreased usage of materials.

Claims (1)

The invention relates to electrical engineering and can be used for heating liquids, in particular for electric heating and hot water supply. The induction fluid heater contains a housing 14, a transformer with a multi-rod ferromagnetic core 1 located on it with a multiphase primary winding 2 connected to the AC mains and a secondary winding being a heat exchanger made in the form of a hollow chamber 4 with a lower input 5 and upper output 6 pipes for the passage of the heated fluid. In the chamber 4 there are through vertical channels 7 with electrically conductive walls 8, in each of which the core rods 1 of the transformer are installed with a gap. The proposed induction fluid heater has a higher efficiency and reduced material consumption.
