Abstract

The invention relates to the technical field of air-conditioner heating, in particular to an electric heater. The metal ceramic hybrid PTC (Positive Temperature Coefficient) fast electric heater comprises a heating component, wherein the heating component is connected with two electrodes and comprises a heating ceramic plate and a metal PTC heating wire or strip; and one electrode is connected with one end of the heating ceramic plate, the other end of the heating ceramic plate is connected with one end of the metal PTC heating wire or strip, and the other end of the metal PTC heating wire or strip is connected with the other electrode. Due to adoption of the technical scheme, the metal ceramic hybrid fast electric heater not only has the advantages of stable performances, high efficiency, long service life, capability of being formed by bening and the like of a metal PTC electric heater, but also has the advantages of current limiting and temperature limiting of a ceramic PTC electric heater.

Description

technical field [0001] The invention relates to the technical field of air conditioning heating, in particular to an electric heater. Background technique [0002] Electric heaters are generally divided into two types, traditional ceramic PTC electric heaters and the latest metal PTC electric heaters. Ceramic PTC electric heaters have the advantages of current limiting and temperature limiting, and semiconductor switch type, but their mechanical strength is poor, multiple blocks are connected in parallel and easy to voltage breakdown, posing safety hazards. [0003] Metal PTC electric heaters have the advantages of stable performance, high efficiency, and long life, but metal PTC electric heaters do not have a semiconductor switch type. Contents of the invention [0004] The object of the present invention is to provide a pottery-gold hybrid PTC fast electric heater to solve the above technical problems. [0005] The technical problem solved by the present invention can ...
