Description

Technical Field

[0001] The present disclosure relates to a heating device configured to provide heated air. Background Art

[0002] A heater is a device that generates heat by heating operation and is widely used in various systems, such as a hot air blower for providing hot air or an air conditioning system for a mobile vehicle. Such a heater may be implemented as a positive temperature coefficient (PTC) heater, which adjusts the heating value by controlling the amount of current applied based on the PWM duty cycle.

[0003] In hybrid vehicles or electric vehicles, electric heaters are mainly used due to insufficient or lack of engine coolant required for heating.

[0004] Recently, a heater has been applied to the grille side of the exhaust air. However, this heater has a fixed structure and can only heat the air without a separate airflow direction control function.

[0005] In addition, in order to improve its heat dissipation efficiency, the heater is configured so that the heat dissipation plates are staggered. However, this configuration creates resistance to airflow. In addition, the heater cannot selectively provide radiant heat, and part of the thermal energy is always used as radiant heat, which leads to a decrease in convective heat transfer efficiency.

[0041] Hereinafter, a heating device according to exemplary embodiments of the present disclosure will be described with reference to the accompanying drawings.

[0042] The heating device according to the present disclosure may be applied to an air conditioning system of a mobile vehicle, and may also be applied to various other systems that provide heat for heating.

[0043] The heating device according to the present disclosure may be implemented as various embodiments.

[0044] The heating device includes a housing 100 defining an air flow space S therein. The housing 100 is formed in various shapes according to the purpose of use, and includes an inlet and an outlet for allowing air to flow therethrough.

[0045] Air flows through an air flow space S in the housing 100 , and the air flow space S is provided with a heat conduction plate 200 and a heater 300 .

[0046] The heat conducting plate 200 is provided in plurality. The plurality of heat conducting plates 200 are arranged and rotatably installed in the air flow space S of the housing 100, and a plurality of ventilation holes H are formed in the plurality of heat conducting plates 200.

[0047] The heater 300 is provided in plural. The plural heaters 300 are coupled to the heat conducting plate 200 and perform a heat generating operation. The heater 300 may be a thin film heater that can be attached to the heat conducting plate 200.

[0048] The heat conductive plate 200 may be made of aluminum, and the heater 300 may be implemented as a PTC heater.

[0049] According to the embodiments of the present disclosure, Figure 2 As shown, the heat conducting plate 200 may be arranged across the airflow space S in the housing 100, and may be rotatably mounted to change the flow direction of the air flowing through the airflow space S. For example, the heat conducting plate 200 may be arranged to face the airflow direction in the airflow space S, or may be arranged to extend along the airflow direction in the airflow space S. Therefore, the heat conducting plate 200 may adjust the flow direction of the air flowing through the airflow space S.

[0050] Since the plurality of ventilation holes H are formed in the heat conductive plate 200 , even if the heat conductive plate 200 is disposed to face the air flow direction in the air flow space S, air may flow through the ventilation holes H. As shown in FIG.

[0051] Since the heater 300 is coupled to the heat conductive plate 200, the heater 300 can change position together with the heat conductive plate 200. The heater 300 functions to heat the air flowing through the air flow space S and provide heat to the heat conductive plate 200 through a heating operation, thereby improving convective heat transfer performance.

[0052] In order to rotate the heat conductive plate 200 , the heating device according to the present disclosure further includes a link unit 400 connected to a rotation center point P of the heat conductive plate 200 , and a driving unit 500 connected to the link unit 400 to move the link unit 400 to rotate the heat conductive plate 200 .

[0053] The connecting rod unit 400 may be configured to be connected to the rotation center point of the heat conducting plate 200, and convert the linear motion of the heat conducting plate 200 into the rotational motion of the heat conducting plate 200 through the driving unit 500. For example, the driving unit 500 may be implemented as a motor, and the connecting rod unit 400 may be connected to the heat conducting plate 200 through a gear rack mechanism. Therefore, the heat conducting plate 200 may rotate while the driving unit 500 is operating. The driving unit 500 may be controlled by a controller.

[0054] The driving unit 500 may be installed outside the housing 100 so as not to affect air flow, and the link unit 400 passes through the housing 100 so as to be connected to the heat conducting plate 200 .

[0055] According to an embodiment of the present disclosure, when the heat conducting plates 200 are disposed to face the airflow direction in the airflow space S, the heat conducting plates 200 may partially overlap each other in the airflow direction.

[0056] Therefore, when the rotational positions of the heat conductive plates 200 are changed to face the air flow direction in the air flow space S, the heat conductive plates 200 partially overlap each other, thereby improving the efficiency of radiant heat through the heater 300 .

[0057] Specifically, the rotation center points of the heat conducting plates 200 are located on the same line. Each heat conducting plate 200 includes a side portion 210 and another side portion 220, which are formed to be opposite to each other with respect to the rotation center point and extend along a straight line. When the heat conducting plates 200 are arranged to face the airflow direction in the airflow space S, one side portion 210 of each heat conducting plate 200 and another side portion 220 of an adjacent heat conducting plate 200 may overlap each other.

[0058] Therefore, since the rotation center points of the heat conducting plates 200 are located on the same line, a structure in which the heat conducting plates 200 are connected to each other through the link unit 400 and rotate simultaneously is easily formed. In addition, since the rotation center points of the heat conducting plates 200 are located on the same line, when the heat conducting plates 200 rotate to face the airflow direction in the airflow space S, one side portion 210 of each heat conducting plate 200 and the other side portion 220 of the adjacent heat conducting plate 200 can overlap each other in an inclined direction. One side portion 210 and the other side portion 220 of each heat conducting plate 200 can be formed to have the same length.

[0059] When the heat conducting plates 200 are disposed to face the airflow direction in the airflow space S, one side portion 210 of each heat conducting plate 200 and another side portion 220 of an adjacent heat conducting plate 200 may be spaced apart from each other so that air flows therebetween.

[0060] In addition, when the heat conducting plates 200 are arranged to face the airflow direction in the airflow space S, the ventilation holes H formed in different heat conducting plates 200 may be staggered from each other. When the heat conducting plates 200 are arranged to extend along the airflow direction in the airflow space S, the heater 300 coupled to each heat conducting plate 200 may face the adjacent heat conducting plates 200.

[0061] In other words, if Figure 2 As shown, since the heat conducting plates 200 are rotated at the same angle at the same time, when the heat conducting plates 200 are arranged to face the airflow direction in the airflow space S, the heat conducting plates 200 are oriented in the same inclined direction, and one side portion 210 of each heat conducting plate 200 and the other side portion 220 of the adjacent heat conducting plate 200 face each other. In this case, since the heat conducting plates 200 are arranged to be oriented in an inclined direction, one side portion 210 of each heat conducting plate 200 and the other side portion 220 of the adjacent heat conducting plate 200 are spaced apart from each other, so that air flows between them. Therefore, the air flowing through the airflow space S in the housing 100 passes through the ventilation holes H in the heat conducting plates 200 and diffuses between one side portion 210 of each heat conducting plate 200 and the other side portion 220 of the adjacent heat conducting plate 200, so that the heating area by the heater 300 can be increased.

[0062] In addition, if Figure 3 As shown, when the heat conducting plates 200 are arranged to extend in the airflow direction in the airflow space S, the heater 300 coupled to each heat conducting plate 200 can provide heat to the adjacent heat conducting plates 200. Therefore, the heat conducting plates 200 can disperse radiant heat, thereby improving convective heat transfer performance.

[0063] On the other hand, the heater 300 may be disposed on a surface of the heat conductive plate 200 opposite to the air flow direction in a state where the heat conductive plate 200 is disposed to face the air flow direction in the air flow space S. Therefore, since the heater 300 generates heat in a direction in which heat should be provided in the air flow space S in the housing 100, the radiation heat transfer performance is ensured.

[0064] As described above, according to an embodiment of the present disclosure, the rotation position of the heat conducting plate 200 is determined according to the mode. That is, in the radiation mode, the heat conducting plate 200 may be arranged to face the airflow direction in the airflow space S, and in the convection mode, the heat conducting plate 200 may be arranged to extend in the airflow direction in the airflow space S.

[0065] Radiation mode is a mode used to improve the performance of radiation heat transfer. Figure 2 As shown, since the heat conducting plates 200 are arranged to face the airflow direction in the airflow space S, the heat conducting plates 200 partially overlap each other in the oblique direction. Therefore, the heater 300 coupled to the heat conducting plates 200 is oriented along the airflow direction, thereby improving the radiation heat transfer efficiency. In addition, the air is heated by the heater 300 when flowing between the heat conducting plates 200.

[0066] Convection mode is a mode used to improve convection heat transfer performance. Figure 3 As shown, since the heat conducting plates 200 are disposed to extend in the air flow direction in the air flow space S, the air flow resistance through the air flow space S is reduced. In particular, since the heat conducting plates 200 are disposed to face each other, the heat generated from the heater 300 coupled to each heat conducting plate 200 is transferred to the adjacent heat conducting plates 200. Therefore, the energy wasted as radiant heat is reduced, thereby facilitating the increase of the temperature of the convection heat.

[0067] According to another embodiment, Figure 4 As shown, the rotation center points of the heat conducting plates 200 are located on the same line, and each heat conducting plate 200 includes a first panel portion 230 and a second panel portion 240, which are formed to be opposite to each other relative to the rotation center point. The first panel portion 230 and the second panel portion 240 may be formed to be spaced apart from each other and may include a plurality of ventilation holes H formed therein.

[0068] Therefore, when the heat conducting plates 200 are disposed to face the airflow direction in the airflow space S, the first panel portion 230 of each heat conducting plate 200 and the second panel portion 240 of the adjacent heat conducting plate 200 may partially face each other in the airflow direction.

[0069] The heat conducting plate 200 may be arranged across the airflow space S in the housing 100, and may be rotatably installed in the airflow space S in the housing 100. The first panel portion 230 and the second panel portion 240 of each heat conducting plate 200 may be formed to be spaced apart from each other, and a vent H may be formed in each panel portion. Therefore, the heat conducting plate 200 may change the flow direction of air flowing through the airflow space S according to the rotational position.

[0070] For example, the heat conducting plate 200 may be disposed to face the airflow direction in the airflow space S, or may be disposed to extend along the airflow direction in the airflow space S. Therefore, the heat conducting plate 200 may adjust the flow direction of air flowing through the airflow space S.

[0071] Specifically, the rotation center points of the heat conducting plates 200 are located on the same line, and when the heat conducting plates 200 are arranged to face the airflow direction in the airflow space S, the first panel portion 230 of each heat conducting plate 200 and the second panel portion 240 of the adjacent heat conducting plate 200 can be arranged to be spaced apart from each other in the airflow direction.

[0072] like Figure 4 As shown, since the rotation center points of the heat conducting plates 200 are located on the same line, a structure can be formed in which the heat conducting plates 200 are connected to each other through the link unit 400 and rotate simultaneously.

[0073] In addition, since the first panel portion 230 and the second panel portion 240 of each heat conducting plate 200 are formed to be spaced apart from each other, when the heat conducting plate 200 is set to face the airflow direction, the first panel portion 230 of each heat conducting plate 200 and the second panel portion 240 of the adjacent heat conducting plate 200 can overlap each other in the airflow direction in the airflow space S.

[0074] Each of the heat conducting plates 200 may include a connection end portion 250 connecting the first panel portion 230 and the second panel portion 240 , and the connection end portion 250 may be connected between the first panel portion 230 and the second panel portion 240 and perpendicular to the first panel portion 230 and the second panel portion 240 .

[0075] In this way, each heat conducting plate 200 may include a first panel portion 230, a connection end portion 250, and a second panel portion 240, and the first panel portion 230 and the second panel portion 240 may extend from respective ends of the connection end portion 250 in opposite directions and be perpendicular to the connection end portion 250. The first panel portion 230 and the second panel portion 240 of each heat conducting plate 200 may be formed to have the same length.

[0076] Therefore, when the heat conducting plate 200 is set to face the airflow direction in the airflow space S, the first panel portion 230 of each heat conducting plate 200 and the second panel portion 240 of the adjacent heat conducting plate 200 can be set to be spaced apart from each other in the airflow direction, so that air can flow between the first panel portion 230 and the second panel portion 240.

[0077] In addition, a ventilation hole H may be formed in the connection end 250 of the heat conducting plate 200. Therefore, when the heat conducting plate 200 is arranged to extend in the airflow direction in the airflow space S, the first panel portion 230 and the second panel portion 240 are arranged to extend in the airflow direction, thereby reducing resistance to air flow. In addition, since air passes through the ventilation hole H in the connection end 250, airflow loss caused by the connection end 250 is reduced.

[0078] On the other hand, when the heat conducting plates 200 are arranged to face the airflow direction in the airflow space S, the ventilation holes H formed in different heat conducting plates 200 may be staggered from each other. When the heat conducting plates 200 are arranged to extend along the airflow direction in the airflow space S, the heater 300 coupled to each heat conducting plate 200 may face the adjacent heat conducting plates 200.

[0079] like Figure 4 As shown, since the heat conducting plates 200 rotate at the same angle at the same time, when the heat conducting plates 200 are arranged to face the airflow direction in the airflow space S, the first panel portion 230 and the second panel portion 240 are arranged across the airflow space S, and the first panel portion 230 of each heat conducting plate 200 and the second panel portion 240 of the adjacent heat conducting plate 200 face each other in a mutually spaced state.

[0080] In addition, since the first panel portion 230 of each heat conducting plate 200 and the second panel portion 240 of the adjacent heat conducting plate 200 are spaced apart from each other, air can flow between the first panel portion 230 of each heat conducting plate 200 and the second panel portion 240 of the adjacent heat conducting plate 200. Therefore, the air flowing through the airflow space S in the housing 100 passes through the ventilation holes H in the heat conducting plate 200 and diffuses between the first panel portion 230 of each heat conducting plate 200 and the second panel portion 240 of the adjacent heat conducting plate 200, so that the heating area by the heater 300 can be increased.

[0081] In addition, if Figure 5As shown, when the heat conducting plate 200 is arranged to extend in the air flow direction in the air flow space S, air flows through the ventilation holes H formed in the connection end portions 250 of the heat conducting plate 200, the first panel portions 230 of the heat conducting plate 200 face each other, and the second panel portions 240 of the heat conducting plate 200 face each other. In this state, the heater 300 coupled to each heat conducting plate 200 provides heat to the panel portion of the adjacent heat conducting plate 200. Therefore, the heat conducting plate 200 can disperse the radiant heat, so that the convective heat transfer performance can be improved.

[0082] On the other hand, the heater 300 may be disposed on a surface of the heat conductive plate 200 opposite to the air flow direction in a state where the heat conductive plate 200 is disposed to face the air flow direction in the air flow space S. Therefore, since the heater 300 generates heat in a direction in which heat should be provided in the air flow space S in the housing 100, the radiation heat transfer performance is ensured.

[0083] As described above, according to another embodiment of the present disclosure, the rotation position of the heat conducting plate 200 is determined according to the mode. That is, in the radiation mode, the heat conducting plate 200 may be arranged to face the airflow direction in the airflow space S, and in the convection mode, the heat conducting plate 200 may be arranged to extend in the airflow direction in the airflow space S.

[0084] Radiation mode is a mode used to improve the performance of radiation heat transfer. Figure 4 As shown, since the heat conducting plates 200 are arranged to face the airflow direction in the airflow space S, the first panel portion 230 of each heat conducting plate 200 and the second panel portion 240 of the adjacent heat conducting plate 200 overlap each other in the airflow direction. Therefore, the heater 300 coupled to the heat conducting plates 200 is oriented in the airflow direction, thereby improving the radiation heat transfer efficiency. In addition, the air is heated by the heater 300 when flowing between the heat conducting plates 200.

[0085] Convection mode is a mode used to improve convection heat transfer performance. Figure 5 As shown, since the heat conducting plates 200 are arranged so that the first panel portion 230 and the second panel portion 240 extend in the air flow direction in the air flow space S, the resistance of the air flow through the air flow space S is reduced. In particular, since the heat conducting plates 200 are arranged to face each other, the heat generated from the heater 300 coupled to each heat conducting plate 200 is transferred to the adjacent heat conducting plates 200. Therefore, the energy wasted as radiant heat is reduced, thereby facilitating the increase of the temperature of the convection heat.

[0086] According to another embodiment, Figure 6 As shown, each heat conducting plate 200 includes: a fixing portion 260 arranged to extend in the airflow direction in the airflow space; a rotating portion 270 rotatably connected to the fixing portion 260 ; and a plurality of ventilation holes H formed in the fixing portion 260 and the rotating portion 270 .

[0087] Specifically, the heat conducting plates 200 may be arranged across the airflow space S in the housing 100, and each heat conducting plate 200 includes a fixed portion 260 and a rotating portion 270. Here, the fixed portion 260 is arranged to extend in the airflow space S of the housing 100 along the airflow direction, and the rotating portion 270 is rotatably mounted to the fixed portion 260. The rotating portion 270 may be closer to the outlet of the airflow space S than the fixed portion 260.

[0088] Ventilation holes H may be formed in the fixing portion 260 and the rotating portion 270 of the heat conductive plate 200 , and the heat conductive plate 200 may adjust the flow direction of air flowing through the air flow space S according to the rotation position of the rotating portion 270 .

[0089] For example, the rotating portion 270 of the heat conductive plate 200 may be disposed to face the airflow direction in the airflow space S, or may be disposed to extend along the airflow direction in the airflow space S. Therefore, the heat conductive plate 200 may adjust the flow direction of air flowing through the airflow space S.

[0090] Specifically, each heat conducting plate 200 may be installed in the housing 100 such that the fixing portion 260 and the rotating portion 270 are connected to each other, and a connection point between the fixing portion 260 and the rotating portion 270 is defined as a rotation center point.

[0091] like Figure 6 As shown, in each heat conducting plate 200, the rotating portion 270 is rotatably connected to the fixed portion 260. Since the fixed portion 260 is arranged to extend in the airflow direction in the airflow space S of the housing 100, and the rotating portion 270 rotates relative to the fixed portion 260, the fixed portion 260 and the rotating portion 270 of each heat conducting plate 200 may be arranged in an "L" shape or an "I" shape, or may be arranged to form an acute angle or an obtuse angle between the fixed portion 260 and the rotating portion 270.

[0092] Here, the rotation center points of the heat conducting plates 200 are located on the same line, so it is easy to form a structure in which the rotating parts 270 of the heat conducting plates 200 rotate simultaneously.

[0093] In this way, the fixing portions 260 of the heat conducting plates 200 are arranged across the airflow space S so as to face each other. That is, the heater 300 coupled to each heat conducting plate 200 faces the fixing portion 260 of the adjacent heat conducting plate 200 and provides heat to the fixing portion 260. Therefore, the heat conducting plates 200 can disperse radiant heat, so that convective heat transfer performance can be improved.

[0094] In addition, in each heat conduction plate 200 , the rotating portion 270 rotates relative to the fixing portion 260 , and thus, the air flow direction and the radiant heat emission direction of the heater 300 can be adjusted according to the rotation position of the rotating portion 270 .

[0095] As described above, according to another embodiment of the present disclosure, the rotation position of the rotating portion 270 of the heat conducting plate 200 is determined according to the mode. That is, in the radiation mode, the rotating portion 270 of the heat conducting plate 200 may be arranged to face the airflow direction in the airflow space S, and in the convection mode, the rotating portion 270 of the heat conducting plate 200 may be arranged to extend in the airflow direction in the airflow space S.

[0096] Radiation mode is a mode used to improve the performance of radiation heat transfer. Figure 6 As shown, the rotating portion 270 of the heat conducting plate 200 is arranged to face the airflow direction in the airflow space S. Therefore, the heater 300 coupled to the rotating portion 270 of the heat conducting plate 200 is oriented in the airflow direction, thereby improving the radiation heat transfer efficiency. In addition, the air is heated by the heater 300 provided on the fixed portion 260 and the rotating portion 270, and flows through the ventilation holes H in the rotating portion 270.

[0097] Convection mode is a mode used to improve convection heat transfer performance. Figure 7 As shown, since the rotating part 270 of the heat conducting plate 200 is arranged to extend in the air flow direction in the air flow space S, the resistance of the air flow passing through the air flow space S is reduced. In addition, since the fixed parts 260 of the heat conducting plate 200 are arranged to face each other, the heat generated from the heater 300 coupled to the fixed part 260 of each heat conducting plate 200 is transferred to the fixed part 260 of the adjacent heat conducting plate 200. Therefore, the energy wasted as radiant heat is reduced, thereby easily increasing the temperature of the convection heat. In addition, the air flow direction can be changed according to the rotation angle of the rotating part 270.

[0098] It can be clearly seen from the above description that the heating device with the above-mentioned structure can provide heat for heating in various modes according to user requirements through the rotation of the heat conduction plate, such as airflow direction control mode, radiation heat dedicated mode and convection heat dedicated mode, thereby improving user satisfaction.

[0099] In addition, the heat conduction plate can improve the heating efficiency by ensuring thermal efficiency according to a mode corresponding to the purpose of use.

[0100] Although the preferred embodiments of the present disclosure have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the disclosure as disclosed in the accompanying claims.
