Abstract

The present invention relates to a coolant heater comprising: a heating element for heating coolant; a first housing for accommodating the heating element; a cover plate for sealing the first housingin which the heating element is accommodated; a temperature fuse provided in an external space formed by coupling the first housing and the cover plate, and disposed to be adjacent to the cover plate;and a second housing for pressing the temperature fuse so as to pressurize the same toward the cover plate, wherein overheat sensing responsiveness of the heating element is improved such that the overheat of the heating element can be prevented, and failure factors in a part in which the temperature fuse is coupled are reduced such that a durability is improved.

Description

technical field [0001] The present invention relates to a coolant heater capable of heating a vehicle coolant using a jacket heater and preventing overheating of the jacket heater as a heating element. Background technique [0002] Currently the most common type of vehicle is a vehicle having an engine powered by gasoline, diesel, etc. as a driving source. However, such energy for vehicles causes various problems such as environmental pollution and reduction in oil reserves, and the necessity of new energy is increasing. Therefore, electric vehicles, hybrid vehicles, fuel cell vehicles, and the like are being actually used or are being developed. [0003] However, unlike conventional vehicles using oil-powered engines, it is impossible or difficult to apply a heating system using coolant to electric vehicles, hybrid vehicles, or fuel cell vehicles. That is, in a conventional vehicle having an engine powered by oil as a driving source, a large amount of heat is generated fr...
