Embodiment Construction

[0034] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0035] The electric heater can convert electric energy into heat energy, and is suitable for heating the working medium in the state of liquid or vapor-liquid mixture. The heating method is to energize the electric heater by supplying electricity, so that the heating element will generate heat after being energized and heat the working medium. . Electric heaters can be used in technical fields such as vehicles, and provide heat for working conditions that require heat.

[0036] Please refer to Figure 1-Figure 26 , Figure 1-Figure 26 It is the first embodiment of electric heater. The electric heater 100 includes a housing 1, a fluid chamber 2, an isolation part 3, a driving module 4, a control module 5, a heating element 6, a wiring part 7, and an inlet 81 and an outlet 82. 6 generates heat and heats the working medium in the fluid chamber 2.

Abstract

An electric heater is used for a vehicle and comprises a heat transfer wall, heating elements and a fluid cavity; the heat transfer wall comprises a transfer wall first side part, the transfer wall first side part faces towards the fluid cavity and is part of the wall forming the fluid cavity, the heating elements are located on the side, away from the fluid cavity, of the heat transfer wall and do not make direct contact with a working medium in the fluid cavity, accordingly, the situation that the safety risk occurs due to the fact that the heating elements are corroded by the working mediumcan be avoided, and meanwhile, the situation that when the heating elements are broken, the working medium is electrified, and the safety risk occurs can be avoided.

Description

【Technical field】 [0001] The invention relates to the technical field of vehicles, in particular to an electric heater. 【Background technique】 [0002] At present, the commonly used electric heater for vehicles is a metal tube electric heater, which directly immerses the electric heating tube in the cooling liquid, and energizes to generate heat. Although the metal tube electric heater has high thermal efficiency and fast heating, sometimes there is a danger of the metal tube being corroded or cracked, which poses a certain safety risk. 【Content of invention】 [0003] The purpose of the present invention is to provide an electric heater with relatively high safety performance. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: an electric heater, which is used for vehicles, includes a heating element and a heat transfer wall, and the electric heater includes a fluid cavity, an inlet and an outlet, and the fluid ...
