Microwave heater for heating liquid and/or gases

Abstract

The invention relates to a microwave heater for heating liquid and/or gases, which consists of a heating chamber, a microwave generator and a temperature measurement and control system, wherein the heating chamber consists of three functional layers, namely an external wave-reflecting heat-conducting metal shell, a medium wave absorbing and heating layer and an internal wave-transmitting thermal insulation layer. The microwave heater is characterized in that: after passing through the thermal insulation layer, microwaves emitted by the microwave generator are absorbed by the wave absorbing and heating layer for heating; and heat is transmitted outward to the metal shell which transmits the heat to surrounding liquid and/or gases to realize the heating of flowing or static liquid and/or gases at last. The microwave heater unit with the structure can be used singly or a plurality of microwave heater units are used in serial and/or parallel connection. The microwave heater has the advantages of simple structure, low manufacturing cost, high thermal efficiency, easy replacement, maintenance and carrying and high safety due to non-contact heating, and can be used as a heat source in various fields such as large and small shower water heaters, hydrothermal heating, hot air heating and industrial production.

Description

technical field [0001] The invention relates to a heater, in particular to a microwave heater used for heating liquid and / or gas, which belongs to the technical field of microwave heating. The heater can quickly heat the flowing or still liquid and / or gas around it, and can be used as a heat source in various fields such as shower water heater, hydrothermal heating, hot air heating, water dispenser, cooking and industrial production. Background technique [0002] At present, there are four main types of heaters used for heating fluid (including liquid and / or gas) according to the way they generate heat, namely electric heating (such as: electric heating tube), gas-fired, coal-fired or solar-powered. It has its limitations: electric heating generally belongs to contact heating, and there are hidden dangers of electric leakage (for example: electric heating tube rupture), and the safety is not good; gas-fired and coal-fired heating have the risk of gas leakage and poisoning, a...
