PORTABLE HYBRID THERMAL CONTROLLED HEATING UNIT FOR FLUIDS

Abstract

The present invention relates to the technical field of portable devices for heating liquids by electromagnetic induction. The technical problem addressed is the difficulty of keeping beverages hot while on the go, with precise temperature control and energy efficiency, without relying exclusively on external heat sources. The proposed solution consists of a portable thermos that integrates a planar induction coil in its base, controlled by a high-frequency inverter stage and an intelligent electronic unit with PID algorithms. Heat is transferred through a removable ferromagnetic jacket, without direct contact with the liquid. The system includes temperature, weight, and level sensors, a rechargeable battery with a battery management system (BMS), a user interface for selecting thermal profiles, and electromagnetic shielding.This invention is applicable in contexts of travel, fieldwork, outdoor activities and situations where thermal autonomy with safety and precision is required.
