As shown in FIG. 1, the heat core sensor 200 of the vehicle heating apparatus according to the present embodiment includes a dual heat core 250 of up / down or left / right.

Hereinafter, the dual heat core 250 will be described in the present embodiment, but it should be noted that three or more heat cores capable of independent control can be assembled and implemented according to the embodiment.

The dual heat core 250 includes a first heat core 251 and a second heat core 252 that are independently operable (i.e., independently controllable). The first heat core 251 and the second heat core 252 are assembled by the main housing 260. In this embodiment, the dual heat core 250 is assembled by separating the upper and lower parts. However, the dual heat core 250 may be assembled separately in the left / right direction or may be assembled before / after Or may be embodied in any shape.

In the present embodiment, the first heat core 251 and the second heat core 252 are shown to have the same size and area. Therefore, the first heat core 251 and the second heat core 252 have the same number (for example, three) of heat RODs 240. However, the first heat core 251 and the second heat core 252 may be configured to have different sizes and areas, so that the heat ROD (heat ROD) embedded in each of the heat cores 251 and 252 240 may also vary.

The heat load 240 is implemented by a PTC device that generates heat using a power source supplied through a power terminal (+) terminal and a (-) terminal, and the PTC device indirectly contacts the heat bar, .

Each of the heat RODs 240 embedded in the first and second heat cores 251 and 252 is connected to one end of the main housing And is configured to receive power to each heat load 240 in a parallel manner by a board detector 220. The power board assay 220 is shown in more detail in FIG.

Power terminals of the heat loads 240 installed in the first heat core 251 and the second heat core 252 are connected to the power board seal 230 to protect the power terminals, And the power board detector 220 is coupled thereto.

The power board cover 210 is coupled to the power board assembly 220. The power board cover 210 prevents external terminals of the heat load 240 and the power board 200 from being exposed to the outside, thereby preventing a safety accident.

2 is an exemplary diagram showing a more detailed configuration of the power board detector 220 in FIG.

2, the power board detector 220 is connected to a power supply terminal (not shown) of each of the heat RODs 240 installed in the first heat core 251 and the second heat core 252, In parallel manner.

2, the power board detector 220 is connected to the (+) power supply terminal of each of the heat RODs included in the first and second heat cores 251 and 252, A second terminal 222 for commonly connecting negative power terminals of respective heat rods incorporated in the first heat core 251, and a second terminal 222 for commonly connecting negative power terminals of the heat ROD built in the first heat core 251, And a third terminal 223 for commonly connecting (-) terminals of respective heat rods contained in the second heat core 252.

FIG. 3 is a diagram illustrating a configuration of a controller for controlling a power supplied to a power board assay in FIG. 2, and FIG. 4 is a diagram illustrating a power control Fig. 8 is an exemplary view for explaining a coupling structure for heat dissipation of a related device; Fig.

As shown in FIG. 3, the controller 300 is configured on one side of the main housing 260 (e.g., on the exposed side of the terminal terminal of the power board attachment). That is, depending on whether the dual heat core 250 according to the present embodiment is an up / down stand-alone type or a left / right stand-alone type, the controller 300 may be mounted on an upper side, a left side or a right side of the main housing 260 Can be configured on one side.

The controller assembly 300 is configured such that the upper housing 350 is coupled to one side of the main housing 260 (the side where the terminal terminal of the power board is exposed) A control-related element 340 (e.g., an IGBT or the like) is coupled.

In this embodiment, two power supply control related elements 340 are coupled to each other to control the power supplied to the first heat core 251 and the second heat core 252. At this time, the device 340 related to the power control may be further coupled corresponding to the number of the heat cores.

Meanwhile, the heating unit 341 of the device 340 related to the power control is coupled to the upper housing 350 to be in contact with the heating unit. Accordingly, each terminal (for example, the power supply terminal and the control terminal) of the element 340 related to the power supply control is directed to the upper side (that is, the opposite side space to be coupled to the upper housing).

At this time, a heat dissipation plate 341 is formed in the heat generating portion of the device 340 related to the power supply control so that the heat dissipation plate 341 contacts the upper housing 350 (see FIG. 4). In this embodiment, the upper housing 350 and the controller cover 310 coupled thereto are made of aluminum material, and the heat generated in the element 340 related to the power supply control So that the heat can be radiated through the upper housing 350 and the controller cover 310. Further, instead of forming the heat dissipation plate 341, the upper housing 350 may be formed so that the shape of the upper housing 350 protrudes out of contact with the element 340 related to the power supply control.

At this time, when the portion protruding from the upper housing 350 convexly protrudes and is in surface contact with the element 340 related to the power supply control, the cross section has a trapezoidal shape and the length of the portion contacting the upper housing 350 Is longer than the length of the portion contacting the power-control-related element 340, so that the heat dissipation can be made easier. The heat radiating plate 341 may be formed in the same shape (a portion where the portion contacting the upper housing 350 is wider).

Further, the heat dissipation performance is improved by allowing the heat dissipation plate 341 formed on the element 340 related to the power supply control to be coupled to the position closest to the vent 351 of the upper housing 350.

The upper housing 350 is in contact with the main housing 260 to transfer heat generated from the power supply control related device 340 to the main housing 260 to dissipate heat. The upper housing 350 is made of an aluminum material having a good thermal conductivity so that the heat generated in the device 340 related to the power supply control is transferred to the upper housing 350 and then the HVAC (Heating, Ventilation, and Air Conditioning: It is also possible to cool the element 340 related to the power supply control by radiating heat by the blower wind of an air conditioner (not shown).

Each terminal of the power source control related device 340 coupled to the upper housing 250 and directed to the upper side (i.e., the opposite side space coupled to the upper housing) and the terminal terminal of the power board detector 220 (221, 222, 223) are electrically connected by a printed circuit board (PCB) 320.

Circuit patterns for electrically connecting the terminals of the device 340 related to the power control and the terminal terminals 221, 222, and 223 are formed on the printed circuit board 320. Accordingly, power is supplied to or cut off from the terminal terminals 221, 222, and 223 under the control of the device 340 related to the power control.

The controller cover 310 prevents the device 340 related to the power supply control and the terminal terminals 221, 222 and 223 coupled to the upper side of the upper housing 250 from being exposed to the outside, do.

FIG. 5 is an exemplary view showing a schematic configuration of a vehicle heating apparatus according to an embodiment of the present invention.

5, the vehicle heating apparatus according to the present embodiment includes a temperature sensing unit 110, a heat generating unit 120, a power driving unit 130, and a control unit 140. As shown in FIG.

The temperature sensing unit 110 senses a temperature inside the vehicle or a temperature of the heat generating unit 120. The temperature sensing unit 110 includes at least one temperature sensing unit 111, 112. The at least one temperature sensing unit 111, 112 may include a contact temperature sensor (not shown) or a non-contact temperature sensor (not shown).

The heat generating unit 120 includes at least two PTC arrays 121 and 122.

The at least two PTC arrays 121 and 122 are formed of the at least two heat cores 251 and 252.

The power driver 130 includes at least two power drivers 131 and 132. The at least two power drivers 131 and 132 control the at least two PTC arrays 121 and 122 (i.e., at least two heat cores 251 and 252).

The power driver 130 may turn on or off the power supplied to the at least two PTC arrays 121 and 122 (i.e., at least two heat cores 251 and 252) under the control of the controller 140 .

The control unit 140 adjusts the internal temperature of the vehicle (or the temperature of the heat generating unit 120) by comparing the temperature sensed by the temperature sensing unit 110 with a predetermined target temperature. The controller 140 controls the power supply to the heater 120 through the power driver 130 to control the heating temperature of the heater 120. That is, the control unit 140 independently controls the heat generation temperatures of the at least two PTC arrays 121 and 122 (that is, at least two heat cores 251 and 252).

At this time, the controller 140 may control the power applied to the heating unit 120 by controlling the power driving unit 130 by a PWM (Pulse Width Modulation) method.

For example, the control unit 140 can independently control the power application time (Duty) applied to each of the at least two PTC arrays 121 and 122 (i.e., at least two heat cores 251 and 252) (See FIG. 6).

6 is a diagram illustrating pulse timing charts for power control of a vehicle heating apparatus according to an embodiment of the present invention.

6, the controller 140 may control the duty ratio of the power applied to the first PTC array 121 and the power applied to the second PTC array 122 to different values.

For example, if it is assumed that the controller 140 applies power to the first PTC array 121 for 1T and the second PTC array 122 supplies power for 2T, the corresponding power consumption is also increased or decreased . ≪ / RTI > Therefore, the power consumption may be reduced by selectively driving the at least two PTC arrays 121 and 122 through duty control of the power source applied to the at least two PTC arrays 121 and 122 according to the state of the vehicle battery .

As described above, according to the present embodiment, in a heating apparatus for operating independently by applying a plurality of heaters in a vehicle such as an electric vehicle, it is possible to prevent the terminal of the element related to the terminal terminal and the power control from being exposed to the outside And further, the heat dissipation of the elements related to the power supply control is easily performed, thereby improving the safety. Further, by selectively driving the at least one PTC array 121 or 122, power consumption is reduced to improve energy efficiency.
