Problems solved by technology
Although the metal tube electric heater has high thermal efficiency and fast heating, there is usually ethylene glycol in the coolant, which has weak acidity and is corrosive to the metal tube to a certain extent, posing a safety risk; the metal tube is in direct contact with the coolant , once the metal pipe has cracks, it will make the coolant electrified, which is very dangerous; in addition, in the absence of coolant, if the electric heater is dry-burned, it will cause serious safety problems

Description
[0001] This application claims the priority of the Chinese patent application with the application number 201611259684.2 and the title of the invention "Electric Heater" filed with the China Patent Office on December 30, 2016, the entire contents of which are incorporated herein by reference. technical field [0002] The invention relates to the technical field of electric heaters, in particular to an electric heater. Background technique [0003] New energy vehicles mostly use electric heating to heat the cockpit, in line with the concept of zero emissions. [0004] At present, a commonly used electric heater is a metal tube electric heater, which directly immerses the electric heating tube in the cooling liquid, and generates heat when it is energized. Although the metal tube electric heater has high thermal efficiency and fast heating, there is usually ethylene glycol in the coolant, which has weak acidity and is corrosive to the metal tube to a certain extent, posing a s...
