Moreover, fasteningprotrusions 222 wrapping around theprotrusion ribs 162 of thecooling water tube 160 disposed on the leftmost side are formed on theconnector 220 side of thePTC heater 200, and thehooks 260 of thePTC heater 200 can be fastened by a structure wrapping around theprotrusion ribs 162′ of thecooling water tube 160 positioned on the rightmost side, as shown inFIG. 4 . - Meanwhile,
FIG. 6 is a view showing the PTC heater of the hybrid heater core system according to an exemplary embodiment of the present invention, andFIG. 7 is a view showing the electrical connection of the PTC heater of the hybrid heater core system according to an exemplary embodiment of the present invention. - As shown in
FIG. 6 , the PTC heater (200) is configured to include atop plate 201, abottom plate 202, and aPTC element 203 interposed therebetween,flow path holes 200A are formed to pass through thetop plate 201 and thebottom plate 202, andguide ribs flow path holes 200A of thetop plate 201 and thebottom plate 202 in directions facing each other. Therefore, the PTC element (203) can be located at a point between theflow path holes 200A adjacent to each other, and both side ends can be supported by theguide ribs - Moreover, as shown in
FIG. 7 , the PTC element can be connected to a positive electrode via theconnector 220, and the top plate and the bottom plate can perform the role of a negative electrode. That is, the positive electrode of the PTC element is connected via theconnector 220, a terminal (L) is disposed along the PTC element, and the positive electrode is connected via the terminal. Moreover, since the entire top plate and bottom plate form a negative electrode, a configuration of an internal circuit is simplified. Of course, in case where the terminal is disposed between the top plate and thePTC element 203, an insulator will be interposed and insulated between the terminal and the top plate. According to the hybrid heater core system having a structure as described above, it is possible to integrate the heater core and the PTC heater of the prior art by simply fastening and assembling these elements, and it is possible to maximize the heating performance through the optimization of a structure. - Further, weight and cost are reduced by the integrated structure, flow resistance is reduced by forming a continuous flow path, and thus the heating efficiency is maximized.
- For convenience in explanation and accurate definition in the appended claims, the terms “upper”, “lower”, “inner” and “outer” are used to describe features of the exemplary embodiments with reference to the positions of such features as displayed in the figures.
- The foregoing descriptions of specific exemplary embodiments of the present invention have been presented for purposes of illustration and description. They are not intended to be exhaustive or to limit the invention to the precise forms disclosed, and obviously many modifications and variations are possible in light of the above teachings. The exemplary embodiments were chosen and described in order to explain certain principles of the invention and their practical application, to thereby enable others skilled in the art to make and utilize various exemplary embodiments of the present invention, as well as various alternatives and modifications thereof. It is intended that the scope of the invention be defined by the Claims appended hereto and their equivalents.
