Electric heater for air conditioner of automobile

Abstract

The invention provides an electric heater for an air conditioner of an automobile and belongs to the indoor heating equipment of an automobile, in particular to an electric heating device arranged in an air conditioner of an automobile. The electric heating device comprises a heating core body electrically powered by an electrode component, wherein the heating core body is formed by the superposition of a heating component and a heat dissipation component; the heating core body is provided with a core body protection plate component consisting of a first core body protection plate arranged onone side of the heating core body and a second core body protection plate arranged on the other side of the heating core body; a tight spring clamp is arranged on the end part of the heating core body provided with the core body protection plate component; a lower bracket is arranged on one side of the heating core body, an upper bracket is arranged on the other side of the heating core body, andthe lower bracket is provided with a lower bracket mould cavity adopting a mould cavity structure capable of accommodating the corresponding end part of the heating core body clamped by the core bodyprotection plate component; and the upper bracket is provided with an internal mould hole which is matched with the corresponding end part of the heating core body clamped by the core body protectionplate component. The electric heating device has the advantages of simple assembly process, safety and reliability and effective improvement of heating efficiency of the heater.

Description

technical field [0001] The invention belongs to vehicle indoor heating equipment, in particular to an electric heating device arranged in an automobile air conditioner. Background technique [0002] When the car is just started or for a period of time after starting, the heat delivered by the engine coolant cannot quickly heat the car interior, nor can it meet the defrosting and defogging requirements of the car. In order to solve such problems and improve the comfort of the car, people use the An additional device is installed in the air conditioner - an electric heater. [0003] For example, the published Chinese patent: 200310123139.7 relates to a new construction principle of an electric heater, wherein the functions of the frame and the elastic device are separated from each other. As a frame for the electric heater, a housing comprising two half shells is used. A positioning aid for the PTC heating element is arranged in the housing. The longitudinal sides of the ho...

Problems solved by technology

[0006] In the known technology, for the assembly of parts of electric heaters, such as heating components, cooling fins, etc., some are bonded with silica gel. This kind of tooling measures has problems such as aging of silica gel, unstable power, and rapid decay of heater functions. problems, thus affecting the normal use of electric heaters; some use a frame to position heating components, heat dissipation fins and other parts in it. This kind of tooling measures has large application limitations, poor compatibility, complex assembly structure, and high industrial costs.
