An electric vehicle air conditioner silicone heating film heater

Abstract

The invention relates to an electric vehicle air conditioner silicone rubber heating film heater comprising a shell and a plurality of silicone rubber heating sheet components arranged in the shell. The silicone rubber heating sheet components are arranged in a mutually spaced manner. Energizing leads connected to the silicone rubber heating sheet components are connected in parallel. Each silicone rubber heating sheet component comprises a long-strip-shaped heat dissipation aluminum plate and a long-strip-shaped silicone rubber heating film stuck to the heat dissipation aluminum plate, wherein the heat dissipation aluminum plate is provided with two gap adjusting blocks close to the two ends of the heat dissipation aluminum plate. The two ends of each heat dissipation aluminum plate are provided with two through holes each and the two sides in the shell are provided with two connecting rods each; the connecting rods penetrate through the through holes of the heat dissipation aluminum plates; the two ends of the heat dissipation aluminum plates are fixed to the connecting rods on the two sides of the shell. The electric vehicle air conditioner silicone rubber heating film heater is neat in layout and convenient to disassemble and assemble; each silicone rubber heating sheet component is relatively independent, so that maintenance and replacement are convenient. The electric vehicle air conditioner silicone rubber heating film heater are high in thermal conversion efficiency and high in temperature rise speed and can save electric energy effectively.

Description

technical field [0001] The invention relates to an air conditioner for automobiles, in particular to a silicone heating film heater for an air conditioner of an electric automobile. Background technique [0002] With the continuous improvement of society's energy-saving and environmental protection requirements, electric vehicles have become the development direction of modern automobile industry technology. However, the change of the power system has led to the fact that the heating method of traditional fuel vehicles using engine waste heat and setting independent fuel heat sources is no longer applicable to electric vehicles. Generally, electric heating is used to meet the comfort and safety of electric vehicle air conditioning and heating systems. . At present, electric vehicles generally use PTC electric heaters to achieve heating. Usually, glue, brazing, etc. are used to connect the PTC heating plate and heat dissipation fins. The thermal conversion efficiency of the...
