[0079] Example 1

[0080] In such Figure 5 The aluminum through-tube shown (the thickness of the radiating wall is 1.35mm, the thickness of the force-bearing wall is 0.9mm, the force-bearing wall is recessed inward, the outer height is 9.2mm, the inner height is 6.5mm), including the installation of PTC thermistors , PTC thermistor and the wall of the aluminum tube clamp the alumina ceramic plate to form the heating element. After the heating element and the heat sink are arranged at intervals, they are bonded to form the main part by thermal silica gel, and the outermost heat sink on one side is riveted There are 4 temperature sensors, custom-made fixtures are placed on both ends of the main part, and filled with silica gel with heat-resistant temperature of 280℃, thermal conductivity of 1.4 W / (m·K), and adhesiveness of 4MPa until Silica gel fills the space between the mold and the main part, solidifies, and electrically connects the conductive sheet of the PTC thermistor exte...

Abstract

The invention provides an electric heater, a defroster, an air-conditioning heating system and an automobile. The electric heater comprises a frame and a heater body component in the frame, wherein the heater body component comprises a plurality of heat dissipation bars and a plurality of heating elements, and the heat dissipation bars and the heating elements are arranged side by side at intervals. Each heating element comprises a core tube and a PTC thermistor installed in the core tube, heat conducting silica gel is arranged between each core tube and the adjacent heat dissipation bars, and the core tube and the adjacent heat dissipation bars are bonded through the heat conducting silica gel. The end, used for being connected with a current, of the heater body component is wrapped by a sealing waterproof rubber frame, and the sealing waterproof rubber frame is located in the frame. The waterproof performance can reach the IPX 7 level, and the comprehensive performance such as high voltage resistance and vibration performance is still high.

Description

technical field [0001] The invention relates to the heating field of an air-conditioning system of an electric vehicle, and more specifically relates to an electric heater, a defroster, an air-conditioning heating system and an automobile. Background technique [0002] In fuel vehicles, the defrosting and heating of the car in winter use an independent heat source (fuel) heating system or a waste heat (using engine cooling water or waste heat of exhaust gas) heating system. These two kinds of car heating and heating systems all need to rely on the engine of the car, that is to say, the defrosting, defogging and heating in the car can only be implemented when the engine is working. Heating is also impossible. In addition, the heating efficiency of this heating system is very low, and its structure is relatively complicated. It takes 6-10 minutes to supply heat after starting the engine in winter, especially for defrosting. The defrosting of the front windshield of the car re...
