    Abstract: A coolant heating apparatus includes: a housing having a coolant flow path therein and configured to cause coolant to flow into the housing and to flow out from the housing after being heated; a sheath heater provided in an inside of the housing and configured to heat the coolant; and a heat conduction plate provided inside the housing and made of a heat-conductive material. A portion of the heat conduction plate is bent in a shape to enclose an outer circumferential surface of the sheath heater and to be in surface contact with the sheath heater so as to carry out heat conduction with the sheath heater, and a remaining portion of the heat conduction plate is in surface contact with the coolant inside the housing such that the coolant is heated by heat conducted from the sheath heater.

    Abstract: A coolant heater for a vehicle includes: a housing unit having an inlet part through which a coolant is introduced and an outlet part through which the coolant is discharged; a baffle assembly provided in an internal space of the housing unit and having a first flow path through which the coolant flows in a first direction and a second flow path through which the coolant, passing through the first flow path, flows in a second direction different from the first direction; a first heater part provided in the first flow path; and a second heater part provided in the second flow path. The coolant heater makes it possible to obtain an advantageous effect of improving a fast-acting heating performance and heating efficiency.
