Description

Vehicle heating device

[0001] The present invention relates to a vehicle heating device capable of directly heating air blown into the interior of a vehicle by exchanging heat as air passes through a through hole formed in a heat dissipation part coupled to a heating part.

[0002]

[0003] In a vehicle heating system, the heating device responsible for heating the vehicle's interior is designed to heat the vehicle's interior by circulating coolant, which is used to cool the engine, through a heater core to heat the air.

[0004] However, among engines, diesel engines have a high heat exchange rate, so it takes longer than with gasoline engines for the heat exchange medium cooling the engine to heat up during the initial start of a vehicle. Therefore, in winter, vehicles equipped with diesel engines have a problem where the heating of the heat exchange medium is delayed after the initial start, resulting in reduced initial interior heating performance.

[0005] In order to solve the problems described above, an air-heating heater has been proposed that directly heats the air blown into the room using various means.

[0006] Although the above-mentioned air-heating heater has the advantage of enhancing heating performance by directly heating the air, it may hinder miniaturization by occupying space equivalent to the size of the heater, especially in situations where it is difficult to secure sufficient space inside the engine compartment due to the trend toward miniaturization and high efficiency.

[0007] FIG. 1 is a perspective view showing a heat exchanger for heating a vehicle, and FIG. 2 and FIG. 3 are an assembled perspective view and an exploded perspective view showing an electric heating auxiliary heater of FIG. 1.

[0008] As described above, a conventional heating heat exchanger comprises: a first header tank (10) and a second header tank (20) spaced apart from each other and having an inlet pipe (11) and an outlet pipe (12) for a heat exchange medium; a plurality of tubes (30) with one end connected to the first header tank (10) and the other end connected to the second header tank (20) through which the heat exchange medium flows; heat exchange fins (40) interposed between the plurality of tubes (30); and an electric heating auxiliary heater (50).

[0009] And the electric heating auxiliary heater (50) comprises: a heating assembly (51) that generates heat electrically; heat dissipation fins (52) installed on both sides of the heating assembly (51); a heat blocking member (53) laminated on the outer side of the heat dissipation fins (52); and mounting members (54) installed at both ends of the heating assembly (51), the heat dissipation fins (52), and the heat blocking member (53) to mount them at a predetermined location on an object. Thus, when power is applied to the heating assembly (51) and it is heated, heat is transferred to the heat dissipation fins (52) adjacent to the heating assembly (51), and the air can be heated by heat exchange as it passes through the corrugated heat dissipation fins (52).

[0010] However, conventional vehicle heating devices using such heating assemblies and heat dissipation fins suffer from reduced thermal efficiency due to heat loss during the heat conduction process, and consequently, there is a problem in that the heating part where heat is generated is prone to overheating in order to satisfy heating performance.

[0043]

[0044] Hereinafter, a vehicle heating device of the present invention having the configuration as described above will be explained in detail with reference to the attached drawings.

[0045] FIGS. 4 to 6 are an assembled perspective view, an exploded perspective view, and a front view showing a vehicle heating device according to an embodiment of the present invention, and FIG. 7 is a partial enlarged view of FIG. 6.

[0046] As described above, a vehicle heating device according to one embodiment of the present invention may be configured to include a heat dissipation unit (100), a plurality of partitions (200), a case (300), and a cover (400).

[0047] The heat dissipation unit (100) may include a plurality of heat dissipation fins (110) formed by bending them into a waveform and a connecting unit (120) that connects the plurality of heat dissipation fins (110) in series. Each of the plurality of heat dissipation fins (110) may be formed by extending along the longitudinal direction, so that the length is longer than the width and height. Additionally, the plurality of heat dissipation fins (110) may be spaced apart along the height direction and arranged in parallel. The connecting unit (120) is a part that connects the plurality of heat dissipation fins (110) in series. The connecting unit (120) may connect the ends and other ends of adjacent heat dissipation fins, and the connecting unit (120) may be formed in a form that is integrally connected to the plurality of heat dissipation fins (110). For example, the ends in the longitudinal direction of the plurality of adjacent heat dissipation fins (110) may be connected to each other and the other ends may be connected to each other by the connecting unit (120), so that the plurality of heat dissipation fins (110) can be connected in series. Thus, the connecting portion (120) can be formed alternately on one side and the other side in the longitudinal direction as it goes in the height direction. Additionally, the connecting portion (120) can be formed to protrude outward in the longitudinal direction from both ends of the plurality of heat dissipation fins (110) in the longitudinal direction. In addition, power can be applied to the end of both sides of the plurality of heat dissipation fins (110) of the heat dissipation portion (100), and when power is applied to the heat dissipation portion (100), it can be heated and heat dissipation can be achieved.

[0048] A plurality of partitions (200) are arranged spaced apart in the height direction, and the plurality of partitions (200) can be interposed and coupled between a plurality of heat dissipation fins (110). Thus, a path in which a plurality of heat dissipation fins (110) are electrically connected in series can be maintained by the plurality of partitions (200). Additionally, each longitudinal end of the plurality of partitions (200) can be inserted and coupled into the inner side of the connecting part (120). Furthermore, there may be a gap between the outer surface of the longitudinal end of the partition (200) and the inner surface of the connecting part (120), and there may be a partially contacted portion.

[0049] The case (300) may include a first body (310) and a first rib (320), and the first rib (320) may be formed in multiple numbers so that the multiple first ribs (320) are spaced apart in the longitudinal direction and arranged side by side. The first body (310) may be formed in the shape of a rectangular frame that surrounds the outer perimeter of the heat dissipation part (100) and the multiple partitions (200). The first rib (320) may be formed in a shape that crosses the first body (310) in the height direction so that both ends of the first rib (320) in the height direction may be connected to the first body (310). The heat dissipation part and the multiple partitions may be inserted and connected inside the case (300). For example, a coupling groove (311) is formed in the first body (310) of the case (300), and a longitudinal end of the partition (200) can be inserted into the coupling groove (311) to be coupled. Also, the longitudinal ends of the partition (200) can be supported by contacting the first rib (320).

[0050] The cover (400) may be formed in a shape corresponding to the case (300), and the cover (400) may be attached to one side in the width direction, which is the open side of the case (300). Thus, the cover (400) may cover one side in the width direction of the case (300). The cover (400) may include a second body (410) and a second rib (420), and the second rib (420) may be formed in multiple numbers so that multiple second ribs (420) are spaced apart in the longitudinal direction and arranged side by side. The fourth body (410) may be formed in a rectangular frame shape corresponding to the first body (310) of the case (300). The second rib (420) may be formed in a shape that cuts across the second body (410) in the height direction, so that both ends of the second rib (420) in the height direction may be attached to the second body (410). With the cover (400) attached to the case (300), the second rib (420) can reach the partition (200).

[0051] Thus, a heat dissipation unit (100) and a plurality of partitions (200) are provided on the inside formed by the combination of a case (300) and a cover (400), and the plurality of partitions (200) are combined with the case (300) and the cover (400), so that the heat dissipation unit (100) and the plurality of partitions (200) can be fixed inside the case (300) and the cover (400). Here, the plurality of partitions (200), the case (300), and the cover (400), excluding the heat dissipation unit (100), may be formed of an electrically insulating material. When power is applied to the heat dissipation unit (100), it can be heated and heat dissipation can be achieved. Therefore, when power is applied to the heat dissipation unit (100), the heat dissipation unit (100) can be directly heated and heat dissipation can be achieved, and as a result, efficient heat dissipation is possible from the heat dissipation unit (100), which is a heating element, and heat loss is reduced, thereby improving heat dissipation performance.

[0052] Additionally, an insertion groove (312) into which the longitudinal end and connecting part (120) of the partition (200) are inserted may be formed in the first body (310) of the case (300). Thus, the longitudinal end and connecting part (120) of the partition (200) can be stably positioned inside the insertion groove (312). Furthermore, the longitudinal end of the connecting part (120) inserted into the insertion groove (312) of the case (300) and the adjacent heat dissipation fin (110) may be positioned spaced apart from the insertion groove (312) and the first body (310) of the case (300). Thus, even if dust accumulates around the insertion groove (312) over time, it can be prevented from being electrically connected to other adjacent parts.

[0053] FIGS. 8 and 9 are partial perspective views showing the assembly structure of a case, partition, and cover of a vehicle heating device according to an embodiment of the present invention.

[0054] As illustrated, a position alignment groove (230) into which a first rib (320) and a second rib (420) are inserted may be formed in the partition (200). As illustrated, a position alignment groove (230) is formed on one side and the other side in the height direction of the partition (200), so that the first rib (320) and the second rib (420) can be inserted into and joined to the position alignment groove (230). Thus, the longitudinal position of the partition (200) can be fixed.

[0055] Additionally, the position alignment grooves (230) of the partition (200) may be formed in multiple adjacent but spaced apart from each other. For example, two adjacent but spaced-apart position alignment grooves (230) may be formed as a pair. Thus, in one partition (200) among the adjacent partitions (200), the first rib (320) and the second rib (420) may be inserted into the position alignment groove (230) on the other side in the longitudinal direction of the pair of position alignment grooves (230), and in the other partition (200) among the adjacent partitions (200), the first rib (320) and the second rib (420) may be inserted into the position alignment groove (230) on the one side in the longitudinal direction of the pair of position alignment grooves (230). As a result, a pattern can be formed in which a partition (200) offset to one side in the longitudinal direction and a partition (200) offset to the other side in the longitudinal direction are alternately arranged in the height direction in which multiple partitions (200) are arranged. Accordingly, it may be easy to arrange the longitudinal end of the connecting part (120) inserted into the insertion groove (312) of the case (300) and the heat dissipation fin (110) adjacent thereto so as to be spaced apart from the insertion groove (312) and the first body (310) of the case (300).

[0056] Additionally, a plurality of partitions (200) may be inserted and clamped by fixed protrusions (321, 421) formed in the first rib (320) and the second rib (420). The fixed protrusions (321, 421) may be formed to protrude from both sides in the longitudinal direction from the first rib (320) and the second rib (420). Furthermore, the fixed protrusions (321, 421) may form a pair of two fixed protrusions spaced apart in the height direction, and a partition (200) may be inserted and clamped between the pair of fixed protrusions.

[0057] FIG. 10 is a cross-sectional view showing the assembly structure of a partition and a heat dissipation fin of a vehicle heating device according to an embodiment of the present invention.

[0058] As described above, a plurality of partitions (200) may include a plate (210) and a step (220) formed to protrude from both ends of the plate (210) in the width direction to both sides in the height direction. A heat dissipation fin (110) may be inserted and clamped between the steps (220) at both ends of the plurality of partitions (200) in the width direction. Thus, the heat dissipation fin (110) can be firmly fixed without being dislodged by the steps (220) of the partitions (200).

[0059] FIG. 11 is a perspective view showing the combined structure of a heat dissipation fin and a terminal of a vehicle heating device according to an embodiment of the present invention.

[0060] As described, terminals (500) for power connection can be attached to each of the two end portions of the heat dissipation portion (100). The terminals (500) can be attached to the case (300), and the ends of the terminals (500) can be drawn out to the outside of the case (300). Thus, positive and negative power sources can be connected to the terminals (500).

[0061] Additionally, the terminal (500) may have fixing tabs (510) formed protruding on both sides in the width direction, and, for example, a fixing groove (313) may be formed in the case (300) and a fixing groove (413) may be formed in the cover (400). Thus, the fixing tabs (510) may be inserted into the fixing grooves (313, 413) so that the terminal (500) can be fixed to the case (300) and the cover (400).

[0062] Additionally, a locking projection (330) may be formed protrudingly on the case (300), and a locking hook (430) may be formed on the cover (400). Thus, the locking projection (330) is inserted into a hole formed in the locking hook (430), allowing the case (300) and the cover (400) to be combined so as to be disassembled and assembled.

[0063] FIGS. 12 to 15 are conceptual diagrams showing embodiments of a heat dissipation part of a vehicle heating device according to an embodiment of the present invention.

[0064] As described, the heat dissipation unit (100) may be composed of a single heat dissipation unit, or it may be composed of two or more heat dissipation units divided into two to four zones.

[0065] FIGS. 16 to 19 are conceptual diagrams showing embodiments in which a vehicle heating device according to an embodiment of the present invention is arranged in various ways.

[0066] As described above, a vehicle heating device according to one embodiment of the present invention may be composed of one unit, or it may be composed of two or more vehicle heating devices, with two to four vehicle heating devices arranged in various ways and connected in series.

[0067] The present invention is not limited to the embodiments described above and has a diverse scope of application. Furthermore, it is understood that anyone with ordinary knowledge in the field to which the present invention pertains can make various modifications without departing from the essence of the invention as claimed in the claims.
