The present invention relates to a PT heater and, more specifically, to a PTC heater which: mechanically fixes a heating element, a terminal, an insulating layer, and a heat-radiating unit, which constitute the PTC heater, by bending a fixing projection of a hook structure formed at a heat rod; and further has an auxiliary fixing protrusion capable of fixing the position of the heating element so as to increase the adhesiveness between the PTC element and the heat-radiating unit, thereby enabling performance to improve and facilitating assembly through the heat rod.

An electric heating device includes a housing having a partition wall which separates a connection chamber from a heating chamber for dissipating heat and from which at least one receiving pocket protrudes into the heating chamber as a heating rib. A PTC heating device with at least one PTC element and conductor tracks for energizing the PTC element with different polarities, which are electrically conductively connected to the latter and which are electrically connected in the connection chamber, are received in the housing. The PTC element and at least one of the conductor tracks are received in a heater casing. The heater casing is pressed into the receiving pocket subject to plastic deformation of the heater casing and/or the receiving pocket.

A heater assembly having a lower tank that is provided with an inlet and an outlet and has a first space, a heater case that covers the first space, has at least one heat transfer pocket that is situated in the first space, and has a second space, at least one heating module that is inserted into the heat transfer pocket such that a terminal thereof is situated in the second space, a bus bar block which is accommodated in the second space and to which the terminal is connected, and a PCB module that controls the heating module is provided. The bus bar block includes a bus bar that contacts the terminal, and a first bus bar plate which has a terminal through-hole, through which the terminal passes, and in which the bus bar is arranged.

A heating device for a vehicle is described. The heating device includes a heater core and a housing assembly. The housing assembly includes a housing configured with a protruded portion, a first terminal, and a second terminal. The first terminal is configured on the protruded portion of the housing and adapted to be connected with a first bus bar. The second terminal is configured on a first end of the housing and adapted to be connected with a second bus bar. The first bus bar and the second bus bar are connected to the heater core to provide an electrical connectivity to the heater core. The first terminal and the second terminal are laterally offset to each other, and are at least partially on opposite sides of a reference line coinciding with an edge of a printed circuit board received in the housing.
