Description

Vehicle heating device and vehicle air conditioning device having the same

The present invention relates to a vehicle heating device, and more particularly, to a vehicle heating device that is installed in an air flow path of the vehicle air conditioner and heats air by exchanging heat with air passing therethrough, and to a vehicle air conditioner having the same.

In general, an air conditioner for a vehicle is a device for cooling or heating the interior of a vehicle by heating or cooling air. An air conditioner for a vehicle includes an evaporator, which is a cooling device, and a heater core, which is a heating device, inside an air conditioning case, and air cooled or heated by the evaporator or heater core is selectively blown to each part of the vehicle interior by operating a door. .

Such vehicle heating devices use a heater core using coolant as a heat source, an indoor heat exchanger using a refrigerant as a heat source, and a PTC heater that generates heat by applying power as an auxiliary heating device. In particular, in the case of an electric vehicle without an engine, a PTC heater is used as a main heating device. Korean Patent Registration No. 10-2002378, previously filed, discloses a PTC core structure of a PTC heater.

1 is a cross-sectional view showing a conventional PTC heater structure. In Fig. 1, the vertical direction is the thickness direction.

Referring to FIG. 1, a plurality of PTC elements 1 are arranged side by side, and electrode units 2 having + electrodes and - electrodes are provided on both sides of the PTC elements 1 in the thickness direction. When power is applied through the electrode part 2, the PTC element 1 generates heat. An insulating layer 3 for electrical insulation is coupled to each electrode unit 2, and a heat conductive layer 4 for smooth conduction of heat is coupled to the insulating layer 3. In addition, a heat dissipation fin 5 is coupled to each heat conductive layer 4 to increase a heat dissipation surface area.

In the conventional PTC heater, the heating element is easily broken and is divided into small pieces, and the PTC element (1), the electrode part (2), the insulating layer (3), the heat conductive layer (4), and the heat dissipation fin (5) must be separately configured for each layer. Therefore, there is a problem in that the number of parts increases and each power supply unit must be configured separately. In addition, since each power source must be connected again with a bus bar or the like, there is a problem in that electrical efficiency is lowered and manufacturing cost increases due to an increase in the number of parts.

In addition, the conventional PTC heater has a problem in that the heat transfer path is long and the area of the heating element is small, so the heating rate is lowered, the heat transfer efficiency is lowered, the rapid effect is reduced, and the temperature of the heating element is increased. In addition, in the conventional PTC heater, since the PTC element 1 and the heat conductive layer 4 are rigid, it is impossible to configure them in other shapes such as circular shapes, and consequently, they cannot be installed corresponding to various air flow path shapes.

Since the heating device for a vehicle and the air conditioner for a vehicle having the same according to the present invention are configured by connecting the power supply unit to one, there is no need for parts such as an electrode unit or a bus bar for separate electrical coupling, so the electrical efficiency is excellent and the number of parts is reduced. there is.

In addition, since it is possible to configure a heating device that heats air in a free shape, high-efficiency heating performance can be exhibited in a compact size while minimizing air volume loss of air-conditioning wind. In addition, since the heating element is formed as a single component, the number of components and the manufacturing process may be reduced, thereby reducing manufacturing cost.

As a result, the heating means has a high heating efficiency in a small size. In addition, regardless of the shape of the air conditioning passage, the air conditioning wind is prevented from leaking and the flexible heating module can be firmly fixed.

The vehicle air conditioner 100 according to the first embodiment of the present invention further includes a heating means 200. The vehicle air conditioner 100 may include the heating means 200 together with a heat exchanger (heater core: 103) for heating, or may include only the heating means 200 without a heat exchanger for heating.

The heating means 200 may be provided in at least one of the inside of the air conditioning case 110, the middle of a duct connecting the air conditioning case 110 and the interior of the vehicle, or an end portion of the duct. The heating means 200 heats the air by exchanging heat with the air passing therethrough. The heating means 200 includes a support frame 210 and a flexible heating module 300 . The flexible heating module 300 is provided inside the support frame 210 .

The support frame 210 is provided in an air flow path formed in the air conditioning case 110 of the vehicle air conditioner 100. That is, the support frame 210 is provided in at least one of the inside of the air conditioning case 110, the middle of a duct connecting the air conditioning case 110 and the interior of the vehicle, or the end of the duct.

The support frame 210 is made to correspond to the shape of the duct of the air conditioning case 110 and is inserted into the duct. That is, when the support frame 210 is installed in the air passage inside the air conditioning case 110, the support frame 210 corresponds to the shape of the air passage. In addition, when the support frame 210 is installed in the duct of the air conditioning case 110, the support frame 210 is made to correspond to the shape of the duct.

The flexible heating module 300 includes a planar heating element 500 and a heating element 400 . The planar heating element 500 generates heat by application of power, and is a unit heating unit covered with a film. The heat sink 400 is coupled to the planar heating element 500 and exchanges heat with the air passing therethrough. In this case, the support frame 210 is made of a rigid material and is not deformed, and the flexible heating module 300 is made of a flexible material and is deformable.

The planar heating element 500 is composed of a heating element 520 and a film 510. The heating element 520 is made of a conductor, and + electrode 521 and - electrode 522 are connected to one side. In addition, the heating element 520 forms a pattern of a certain shape, and when power is applied, heat is generated by electrical resistance. That is, one end of the heating element 520 is connected to the + electrode 521 and the other end is connected to the - electrode 522 . In addition, the film 510 is made of a thin shape and is composed of an insulator.

A pair of films 510 are provided and cover both sides of the heating element 520 in the thickness direction. In addition, the film 510 is made of a material that conducts heat well. That is, the heating element 520 is positioned between the pair of films 510, electricity passing through the heating element 520 is insulated by the film 510, and heat generated from the heating element 520 passes through the film 510. It is smoothly transferred to the heat dissipation fin 420 of the heat dissipation body 400 . In addition, the heating element 520 and the heat dissipation element 400 are insulated by a film 510 .

The support frame 210 is made of a cochlea structure having a circular cross-section shape or a polygonal cross-section shape so that the flexible heating module 300 can be wound. The support frame 210 according to the first embodiment of the present invention is composed of a cochlear structure having a circular cross-section. In this case, the duct shape of the air conditioning case 110 has a substantially circular cross section. That is, the cross-sectional shape of the support frame 210 is formed to correspond to the shape of the duct of the air conditioning case 110. In addition, an insertion space 215 through which air can pass is formed inside the support frame 210 .

More specifically, the support frame 210 has a substantially cylindrical body. An inlet pipe 213 having an inlet 215 formed on one side (upstream) side of the body is extended in the air flow direction, and an outlet pipe 214 having an outlet 216 formed on the other (downstream) side is extended. A guide wall 220 formed by winding the circumferential surface narrowly inward to form a wall in the shape of a cochlea extends inside the body in the radial direction.

In addition, a plurality of fastening parts 211 are formed on the outer circumferential surface of the support frame 210, and fastening holes 212 for screw fastening to the air conditioner are formed through the fastening parts 211. On the other hand, at least one rib 230, 240 for reinforcing strength across the transverse or longitudinal direction of the support frame 210 is further provided. The transverse ribs 230 and the longitudinal ribs 240 are disposed orthogonally to each other, and compensate for insufficient strength of the guide wall 220 formed in the shape of a cochlea to prevent deformation.

The heat dissipation body 400 is composed of heat dissipation fins 420 in the form of repeated pleats to increase the heat exchange surface area with air. Radiation fin 420 is formed extending along the longitudinal direction of the planar heating element (500). A heat conductive layer 410 is further provided between the heat dissipation fin 420 and the planar heating element 500, and the planar heating element 500 and the heat conductive layer 410 are in surface contact. The thermal conductive layer 410 supports the heat dissipation fins 420 by attaching the heat dissipation fins 420, and is made of a material that has excellent thermal conductivity and can be bent or bent.

The flexible heating module 300 is configured to be flexibly bent to a curved surface or vertically bent. In addition, the flexible heating module 300 is formed to extend continuously within the support frame 210, and is electrically connected by one power source. In addition, the flexible heating module 300 is inserted and guided into the insertion space 215 of the support frame 210 while being flexibly bent or bent at 90 °, filling all or part of the insertion space 215 .

If an electric heater composed of a planar heating element and a radiating fin is wound in an arbitrary shape without a separate support frame, an arbitrary air leak area inevitably occurs. The air leak area of the electric heater composed of the wound radiating fins mainly occurs in an outer end portion, an inner end portion, and a curved area. For this reason, there is a problem in that it is difficult to predict the air volume and the heat dissipation efficiency is lowered.

That is, in order to wind the electric heater while maintaining a constant quality, a certain or more curvature is required in the curved portion, but an impossible area is generated due to the shape of the electric heater. In particular, it becomes impossible to maintain the curvature toward the inner center of the electric heater. If the electric heater is forcibly crushed to remove the region in which the curvature cannot be maintained, quality control of the heater is difficult and overheating or failure occurs due to loss of the heater.

The heating means 200 according to the first embodiment of the present invention is a flexible heating module composed of a heat dissipation fin 420, a heat conduction layer 410, and a planar heating element 500 having flexibility to freely change shape in a curved or folded form. 300 can be configured to solve the above problems. The flexible heating module 300 is rolled or folded so as to partially or entirely fill the insertion space 215 of the support frame 210 formed to correspond to the shape of the flow path (or duct) through which the air conditioning wind passes and is inserted.

In addition, the heating means 200 according to the first embodiment of the present invention can be inserted and installed in the middle of a duct through which air-conditioning air flows, at the end of a duct, or inside an air-conditioning case. Since the heating unit 200 is connected to one power supply unit, it does not require components such as an electrode unit or a bus bar for separate electrical coupling, so that the electrical efficiency is excellent and the number of components is reduced.

In addition, since the heating means 200 according to the first embodiment of the present invention can be configured as a heating device that heats air in a free form, it is possible to exhibit high efficiency heating performance in a compact size while minimizing air volume loss of air conditioning wind. there is. In addition, since the heating element is formed as a single component, the number of components and the manufacturing process may be reduced, thereby reducing manufacturing cost.

Meanwhile, since the heat transfer path from the heating element to the heat radiating fin is shortened and heat is evenly transferred over a wide area, area use efficiency is increased, and the size of the entire heater can be drastically reduced. As a result, the heating means 200 has a high heating efficiency in a small size. In addition, regardless of the shape of the air conditioning flow path, the flexible heating module 300 can be firmly fixed so that the air conditioning wind does not escape.

11 to 13, the vehicle air conditioner 100 according to the second embodiment of the present invention includes a heating means 200. The heating means 200 is composed of a cochlea structure having a polygonal (rectangular) cross-section. In this case, the duct shape of the air conditioning case 110 has a substantially rectangular cross section. That is, the cross-sectional shape of the support frame 210 is formed to correspond to the shape of the duct of the air conditioning case 110. In addition, an insertion space 215 through which air can pass is formed inside the support frame 210 .

More specifically, the support frame 210 has a substantially rectangular cylindrical body. An inlet is formed on one side (upstream) side of the body in the air flow direction, and an outlet is formed on the other side (downstream) side. Inside the body, a guide wall 220 is extended to form an insertion space 215 so that the flexible heating module 300 can be inserted and guided by forming a wall in the shape of a cochlea. The guide wall 220 extends inwardly while being bent at 90° at each bent portion.

Meanwhile, further referring to FIG. 14 , a bypass passage 250 may be further formed in the support frame 210 . The bypass passage 250 allows some of the air passing through the heating means 200 to bypass without passing through the flexible heating module 300 . The bypass flow path 250 functions to increase the air volume by reducing air resistance by the flexible heating module 300 in an environment where the air volume may decrease.

15 and 16, the heating means 200 according to the third embodiment of the present invention includes a support frame 210 and a flexible heating module 300. The flexible heating module 300 is composed of a planar heating element 500 and a heat dissipation body 400, and the heat dissipation body 400 is composed of a radiation fin 420 extending along the longitudinal direction of the planar heating element 500. Radiating fins 420 are attached to both sides in the thickness direction with respect to the planar heating element 500.

In this way, by configuring the heat dissipation fin 420 on both sides of the planar heating element 500, it is possible to dissipate heat with a higher heating density compared to that configured on the end surface and reduce the size of the heating device.

The support frame 210 is composed of a cochlea structure having a circular cross-section. In addition, the densities of the radiating fins 420 on one side and the radiating fins 420' on the other side in the thickness direction based on the planar heating element 500 are formed differently. That is, the spacing between the creases of the radiating fins 420 of the radiator 400 on one side and the spacing of the creases of the radiating fins 420' of the other side of the radiator 400' on the basis of the planar heating element 500 are different.

On the basis of the planar heating element 500, the radiating fin 420' on the other side of the crease interval is formed wider than the radiating fin 420 on the one side of the crease interval. A heat conductive layer 410 is formed between the planar heating element 500 and the heat dissipating fin 420 on one side, and a heat conductive layer 410 'is formed between the planar heating element 500 and the heat dissipating fin 420' on the other side.

In this way, when the radiating fins are configured on both sides of the planar heating element 500, the spacing of the radiating fins after being wound can be made constant by configuring the densities of the radiating fins attached to the outside and the inside of the circular shape differently according to the curvature. In other words, when the radiating fin is configured with both sides, the radiating fin located outside the circle where the radiating fin is widened and the radiating fin located inside the circle where the radiating fin is folded have different densities or are composed of different types of radiating fins, so both sides after the radiating fin is wound and dried. It is to keep the density of the radiating fins similar.

The heating element 520 forms a pattern of a certain shape, and when power is applied, heat is generated by electrical resistance.

In particular, the heating element 520 is formed only on a portion of the film 510 in the longitudinal direction, so that the heating element 400 corresponds only to the portion where the heating element 520 is formed, and the heating element 520 is not provided in the portion where the heating element 520 is not formed. do. That is, the planar heating element 500 is composed of a heating element 520 and a non-heating element 525 .

For example, the non-heating element 525 may be implemented in the form of a metal plate such as aluminum (Al). The radiating fin 420 is not attached to a portion corresponding to the non-heating element 525 but is attached only to a portion corresponding to the heating element 520 .

A portion of the flexible heating module 300 in which the heating element 520 and the heat dissipating body 400 are not configured corresponds to a curved portion of the sidewall of the support frame 210 . By inserting the planar heating element 500 into each layer partitioned by the interlayer wall 280 of the support frame 210, the planar heating element 500 is bent by 90 ° at the bent portion of each layer and filled. After that, by coupling the cover 290 to the opening of the support frame 210, one heating means 200 is made.

Radiating fins 420 are attached to both sides in the thickness direction with respect to the planar heating element 500.

The support frame 210 is composed of a cochlear structure having a polygonal (rectangular) cross-section. An insertion space portion 215 through which air can pass is formed in the support frame 210, and the insertion space portion 215 is formed as one space. The planar heating element 500 is composed of a heating element 520 and a film 510. The heating element 520 is made of a conductor, and + electrode 521 and - electrode 522 are connected to one side. The heating element 520 forms a pattern of a certain shape, and when power is applied, heat is generated by electrical resistance.

In particular, the heating element 520 is formed only on a portion of the film 510 in the longitudinal direction, so that the heating element 400 corresponds only to the portion where the heating element 520 is formed, and the heating element 520 is not provided in the portion where the heating element 520 is not formed. do.
