The invention relates to an electric heating device with at least one electrically heatable heating element or with a plurality of electrically heatable heating elements, wherein at least one radiator element is thermally connected to the at least one heating element in order to heat a fluid flow, which flows against and/or around and/or through the at least one radiator element, wherein each heating element has at least one heater which heats up when electric current flows through the heater, wherein electrode elements are provided for electrically contacting the heater, wherein the electrode elements contacting a heater are arranged spaced from one another and accommodate at least one of the heater between them, wherein at least two heater are electrically interconnected in series.

A hybrid heater includes a heater core portion connected to a cooling water inflow tube and a cooling water outflow tube at one side and having an inside through which cooling water circulates, and a PTC heater portion fastened to a front of the heater core portion, inside of which a plurality of plate-type PTC rods arranged in parallel in a horizontal direction are provided, and provided at one side with a connector that is connected electrically to the plurality of PTC rods.

The invention relates to a method for producing a corrugated fin element for a heating register or for another heating device, through which corrugated fin element a flow can pass, to a corrugated fin element produced according to such a method, and to a heating register designed with such corrugated fin elements, wherein the corrugated fin elements are produced by unfolding.

Provided is a positive temperature coefficient (PTC) unit for a vehicle heater. The PTC unit according to an exemplary embodiment of the present invention includes: a heat generation part which includes PTC elements; and a heat radiation part which is provided on at least one surface of the heat generation part and includes a heat radiation base material and a heat radiation film provided on at least a portion of an outer surface of the heat radiation base material to improve heat radiation performance. According to the present invention, improved heat radiation performance may be exhibited, and concurrently, heat radiation performance due to excellent durability may be exhibited for a long period of time without a structural change for increasing a specific surface area of a heat radiation part while reducing an air ventilation property, so as to improve heat radiation performance. In addition, since an air ventilation property of the heat radiation part is increased, it is possible to prevent increases in noise and power consumption due to excessive use of peripheral devices such as a fan. Furthermore, since it is possible to prevent overheating of a PTC module and overload of a PTC module control circuit, which are caused by a reduction in the air ventilation property of the heat radiation part, a high-priced and high performance control circuit may not be required, thereby implementing a PTC heater for a vehicle with reduced production costs.

A fluid-heating device for heating fluid includes: a heater having a heat generating part, the heat generating part being configured to generate heat upon application of current; an electric component configured to control the application of the current to the heater; a tank having an opening portion, the tank being configured to accommodate the heat generating part; a top-plate portion configured to close the opening portion of the tank, the top-plate portion being configured to form a fluid chamber through which the fluid flows; and a first communication port and a second communication port configured to allow the fluid to flow through the fluid chamber; wherein the electric component is provided on an outer side of the fluid chamber along the top-plate portion.
