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 includes a heat transfer wall, a heat element and a fluid chamber, the heat transfer wall includes a first side portion of the heat transfer wall, A first side of the heat transferwall faces the fluid chamber, A first side portion of the heat transfer wall is a wall portion forming a portion of the fluid chamber, The heating element is located at a side of the heat transfer wall opposite to the fluid chamber, and the heating element is not in direct contact with the working medium in the fluid chamber, so that the safety risk caused by the corrosion of the working medium onthe heating element can be avoided, and at the same time, the safety risk caused by the electrification of the working medium when the heating element is damaged 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] To achieve the above object, the present invention adopts the following technical solution: an electric heater, which is used in a vehicle, includes a heat transfer wall, a heating element, and a heat transfer portion, the heat transfer wall includes a first side portion, the The first sid...
