A plurality of heat dissipation units 3 are formed between the adjacent heat dissipation units 3 so that the heat dissipation unit 3 is surrounded by the low heat conduction unit 6.

However, such a radiant heater has a limit to the heat-resistant temperature of the material constituting the heater, and if the surface temperature is excessively increased, there is a fear of burning upon contact with the body, and the surface temperature of the heater can not be sufficiently raised. Therefore, the quick-impact is poor and the passenger does not feel a sufficient sense of warmth.

In addition, there is a problem that the heater is overheated during the abnormal operation, and the safety device for preventing the overheating is not complete, which causes a risk of fire.

Hereinafter, a radiant heater for a vehicle according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 3 is a perspective view (a) and an exploded perspective view (b) showing a radiant heater assembly for a vehicle including a radiant heater for a vehicle according to the present invention, and FIG. 4 shows an installation example of a radiant heater assembly 1000 for a vehicle according to the present invention.

As shown in the figure, the radiant heater 100 for a vehicle according to the present invention comprises a radiant heater assembly 1000, which is installed in the vehicle and generates heat when power is applied thereto. Even if passengers pass in winter, It is intended to solve the problem that the heater can not be heated because it can not be sufficiently heated. That is, since the radiant heater assembly 1000 is heated immediately when the power is applied, it is possible to solve the discomfort caused by the cold at the beginning of the ride in winter. At this time, the radiant heater assembly 1000 may be installed on the rear side of the first row seat so as to generate heat toward the passenger on the ridge, and the installation position thereof can be changed as much as the user wishes.

The front cover 400, the safety mesh 300, the radiator heater 100, and the back cover 200 are stacked in this order to form the front cover 400, The safety mesh 300 and the radiator heater 100 may be fixed by being coupled with the back cover 200. Here, the front cover 400 may be formed as a frame-like frame so that the rim portion of the safety mesh 300 may be fixed, and a plurality of engagement holes may be formed in the front cover 400, The fixing pin can be coupled to be inserted into the coupling hole of the front cover 400. [ The safety mesh 300 is formed in a net shape so that the radiant heat generated from the radiant heater 100 is radiated in the front direction and the rim portion can be fixed between the front cover 400 and the back cover 200.

FIG. 5 is a perspective view of the radiant heater 100 for a vehicle according to the present invention, and FIG. 6 is a sectional view taken along line A-A 'of FIG. As shown in the figure, the automotive radiant heater 100 of the present invention mainly comprises a base member 120, a PTFE rod 130, and a heat insulating material 140.

The base member 120 is made of a material having thermal conductivity, particularly, an aluminum material to form a heat generating surface, and can be formed into a plate having a predetermined thickness. At this time, the pettis seed rod 130 is fixed to the rear surface of the base member 120, and when the power is supplied, the Pettis seed element 132 that emits heat is internally interposed to generate heat. The base member 120 receives heat from the seat cushion 130 fixed to the rear surface of the base member 120 and discharges heat toward the passenger toward the passenger. At this time, a coating layer 110 is formed on the front surface .

As shown in the drawing, the heat insulating material 140 is closely adhered to the rear surface of the base member 120 on which the coating layer 110 is not formed and the rear surface of the PTFE rod 130 to reduce heat loss to the rear surface of the radiation heaters 100 And prevents the radiant heater 100 from damaging the peripheral portion due to the heat generating operation of the radiant heater 100. As the heat insulating material 140, foam silicone, an inorganic heat insulating material 140, or the like may be used, and in addition, any material capable of blocking heat may be used without limitation.

The radiant heater 100 of the present invention having the above-described structure emits radiant heat to the front surface of the base member 120 as the PTFE rod 130 generates heat. At this time, the coating layer 110 The radiation heat emission performance is maximized. Specifically, when the coating layer 110 is not formed, the amount of radiant heat radiated to the front of the radiant heater 100 and transmitted to the occupant is only about 40-50% of the heating value of the piston rod 130. However, when the coating layer 110 is formed, the performance of the coating layer 110 is improved to about 80-90% even when heat loss to the rear surface of the radiation heater 100 and loss due to conduction or convection are taken into consideration.

At this time, the coating layer 110 may be an oxide film formed by an anodizing process or a ceramic film, and may be formed to have a predetermined thickness to have electrical insulation. Specifically, in the case of an oxide film by anodizing, it may be formed to a thickness of several micrometers to several tens of micrometers, and in the case of a ceramic, it may be formed to a thickness of 200 micrometers to 300 micrometers. However, the thickness of the coating layer 110 is not limited to the above-described range, and it may be formed to have a proper thickness enough to have a certain radiation heat emitting performance with electrical insulation.

In addition, the radiating heater 100 for a vehicle according to the present invention further comprises a coloring layer 111 on the coating layer 110, so that aesthetics can be secured not only in terms of heat generation performance but also in terms of design. The coloring layer 111 may be formed by coloring the entire surface of the coating layer 110 after forming the coating layer 110 on the base member 120 or by coloring the coating layer 110 by forming an anodizing layer. have. In the anodizing process, the rear surface of the base member 120 is masked, and the coating layer 110 is formed by immersing the backside of the base member 120 in an electrolytic solution and electrically oxidizing the rear surface of the base member 120. At this time, the coating layer 110 is formed by using an electrolyte solution containing the coloring material . When such an anodizing process is applied, coloring can be performed very easily.

At this time, the color of the coloring layer 111 can be formed in a desired color, but in the case of any one of red, white, and black, or a combination thereof, it is more advantageous in terms of radiant heat emission efficiency.

7 is a view illustrating a manufacturing process of the radiant heater 100 for a vehicle according to an embodiment of the present invention. The base member 120 prepared in advance as shown in FIG. 7 (a) is preferably formed into a shape corresponding to the shape of the mounting position through a die casting or a drawing process. Thereafter, the coating layer 110 is formed by anodizing or ceramics (FIG. 7 (b)), and the coating layer 110 is developed (FIG. 7 (c)). Thereafter, a plurality of petty seal rods 130 are attached to the rear surface of the base member 120 to manufacture a heating element (Fig. 7 (d)). Finally, the heat insulating material 140 is laminated as shown in Fig.

7 (d), the radiant heater 100 for a vehicle according to the present invention may further include a fixing member 121 for fixing the piston rod 130 to the base member 120. 8, the fixing member 121 can be easily attached to the base member 120 by using an adhesive member 121a such as a silicone adhesive or the like. As shown in FIG. 7 the caulking member 121b may be formed on the rear surface of the base member 120 when the base member 120 is molded in the step a) so that the PTFE rod 130 may be caulked as shown in Fig.

At this time, it is preferable that the physiside rod 130 is firmly fixed so as to be in contact with the base member 120 completely. When the caulking member 121b is used as the fixing member 121 as described above, unlike the adhesive member 121a in which the radiant heater 100 is heated for a long time, The heat conduction efficiency from the rod 130 to the base member 120 is also excellent.

10 shows a state in which the seat portion 130 is mounted on the base member 120 with the seat portion 122 formed thereon. In order to improve the thermal conductivity of the base member 120 from the base member 120, it is preferable that the base member 120 and the piston 130 are completely in close contact with each other.

However, since the piston rod 130 has a rectangular cross section and is formed in a long rod shape having the Pettis element 132 interposed therebetween at regular intervals along the longitudinal direction, the contact surface with the base member 120 is flat, As shown in FIG. 7 (a), the base member 120 may be formed into a curved shape by being custom-formed according to the mounting position. In this case, the piston rod 130 can not be completely attached to the base member 120, and a clearance can not be generated, thereby lowering the radiation heat emission efficiency.

In order to solve such a problem, the radiating heater 100 for a vehicle according to the present invention has a structure in which the surface of the PTFE rod 130 is fixed to the surface of the PTFE rod 130 when the base member 120 is formed, 122 may be formed. That is, even though the overall shape of the base member 120 is formed as a curved surface, the surface to which the PTFE rod 130 is attached is flat so that the PTFE rod 130 can be closely fixed to the base member 120.

In the meantime, the present invention is a radiant heater 100 for a vehicle that radiates radiant heat as the heat is generated as described above. Hereinafter, the configuration of the piston rod 130 will be described in detail. 11 is an exploded perspective view showing an embodiment of a piston rod 130 constituting a radiant heater 100 for a vehicle according to the present invention.

As shown in the figure, the Pettis rod 130 includes an insulating support 131, a plurality of Pettis seed elements 132 interposed in the space, An electrode layer 133 including a first electrode 133a which is in close contact with the rear surface of the first electrode 133 and a second electrode 133b which is in close contact with the front surface of the first and the second electrodes 133a and 133b, An insulating layer 134 including a first insulating layer 134a and a second insulating layer 134b attached to the entire surface of the second electrode 133b, an insulating support 131, a Pt layer 140, 133, and a housing 135 formed to surround the insulating layer 134 and having a conductive property.

As shown in FIG. 5, the piston rod 130 having such a structure may have a long rod shape, and a plurality of the piston rod 130 may be spaced apart from the base member 120 by a predetermined distance to thereby constitute the automotive radiant heater 100 can do.

The petty-seed rod 130 generates heat by applying positive and negative voltages to the top and bottom surfaces of the Pettis device 132 through the first electrode 133a and the second electrode 133b, respectively . Generally, the resistance does not change according to the temperature, but in the case of a positive temperature coefficient (PTC) device, the resistance rises rapidly when the temperature rises at a certain temperature. If the temperature rises above a certain level, the resistance becomes large, and the amount of current that can flow through the resistor becomes small. As the current decreases, the amount of heat is reduced and the temperature drops again. When the temperature drops, the resistance increases and the heat generation starts.

That is, since the vehicular radiant heater 100 according to the present invention is constructed by applying the Pitti element 132, the temperature of the heater is fixed to the curi point of the Pitti element 132, Temperature control can be advantageous. At this time, the Curie point means that the properties change when the temperature becomes abnormal at a certain critical temperature. Accordingly, durability can be ensured even when the temperature of the heater is maintained at a high temperature of about 100 to 200 degrees Celsius, and there is no danger of overheating since it has a constant temperature characteristic.

12 is a view schematically showing various embodiments of a radiant heater 100 for a vehicle according to the present invention.

12A is a cross-sectional view of a semiconductor device including an insulating support 131, a Pt-Si device 132, a first electrode 133a, a second electrode 133b, a first insulating layer 134a, The second insulating layer 134b and the housing 135 are attached to the base member 120 on which the coating layer 110 is formed (the fixing member is omitted).

12 (b), in the structure of FIG. 12 (a), the second electrode 133b and the second insulating layer 134b are omitted, and the housing 135 is surrounded Structure. This is because the second electrode 133b and the second insulating layer 134b are not formed separately as the housing 135 and the base member 120 have conductivity. If the first electrode 133a is a positive electrode terminal, The housing 135 or the base member 120 serves as a negative terminal. Since the one surface of the PTC device 132 adjacent to the base member 120 does not need to include the electrode layer 133 and the insulating layer 134, the structure of the PTC device 130 is simplified, Can be maintained.

12 (c) shows a structure in which the base member 120 and the housing 135 are integrally formed. That is, since the housing 135 of the piston 130 can also serve as the base member 120, the coating layer 110 is formed on one surface of the piston 130 without the base member 120, The radiant heater 100 for a vehicle may be constructed.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
