Technical Field [0001] The present invention relates to a heating apparatus for a cockpit of a train,

The present invention relates to a heating mechanism, and more particularly, to a heating mechanism used for heating a lower portion of a train cockpit.

A train is a vehicle that travels on a railroad by connecting several locomotives or vans to a locomotive. Trains pull trains or lorries by the traction of a locomotive. Trains are diesel trains and electric trains depending on the power source. Generally, a locomotive is equipped with a cockpit to control train operations, and a railroad engineer sits in the cockpit to control the train.

However, when the train is operated during the winter season, the cold air of the cockpit may interfere with the operation of the railroad engine engineer, which may cause inconvenience to the railroad engineer. In order to solve this problem, it is required to effectively heat the lower portion of the cockpit when the train is operated during the winter season.

An object of the present invention is to provide a heating mechanism for a train cockpit capable of effectively heating a lower portion of a cockpit.

According to an aspect of the present invention, there is provided a heating mechanism for a train cockpit, including a case, a gasket, at least one heating tube, a heat dissipation panel, packing materials, a supporting mechanism, Reflector, and insulation. The case has a case body having an inner space with an open upper portion, and a flange formed along the upper periphery of the case body. The gasket covers the top surface of the flange. The heating tube is disposed in the case body so as to extend in the left and right direction, and generates heat when power is applied. The heat dissipation panel is housed in the case body and has an insertion hole for drawing the left and right ends of the heating tube in a state where the heating tube is inserted into the lower part. The heat generated from the heating tube is accumulated and radiated to the far infrared ray column. The packing materials pack the front and rear ends of the heat dissipating panel against the case body. The support mechanism supports the left and right ends of the heating tube to the case body. The covers cover the upper opening areas located on the left and right sides of the heat radiation panel in the upper opening area of the case body, respectively. The reflection plate is disposed on the lower side of the heat dissipation panel and housed in the case body. The heat insulating material is disposed on the lower side of the reflector and housed in the case body.

The heating mechanism for a train cockpit according to the present invention is embedded in a footstool of a cockpit and radiates a far infrared ray when the train is operated during the winter season, so that the lower part of the cockpit can be effectively heated by the far infrared ray heat. Therefore, the railway engineer can control the train in a comfortable environment.

1 to 6, a heating mechanism 100 for a train cockpit includes a case 110, a gasket 120, a heating tube 130, a heat dissipation panel 140, a packing material 150, A supporting mechanism 160, a cover 170, a reflection plate 181, and a heat insulating material 186. [

The case 110 has a case body 111, and a flange 112. The case body 111 has an inner space in which an upper portion is opened. The case body 111 may have a structure in which portions except the upper portion are clogged. The case body 111 has a hexahedron-like appearance and has a uniform thickness, so that it can have a hexahedron-like internal space.

The flange 112 is formed along the upper periphery of the case body 111. When the case body 111 has a hexahedral appearance, the flange 112 may have a rectangular ring shape. Fastening holes 112a may be formed in the flange 112. The case body 111 and the flange 112 may be integrally made of the same material. The case 110 may be made of a cold rolled steel sheet and then surface-treated by heat-resistant powder coating.

The upper end of the flange 112 may be positioned lower than the upper end of the case body 111. Therefore, the upper end of the case body 111 can protrude from the upper end of the flange 112. The upper end protrusion 111a of the case body 111 may be set to be equal to or smaller than the thickness of the gasket 120. [ Therefore, the inner peripheral surface of the gasket 120 can be held in contact with the outer peripheral surface of the upper end projection 111a of the case body 111. [

Such a case 110 may be embedded in the footstep 11 of the train cockpit 10. The footrest 11 may be provided at the lower portion of the cockpit 10 so that the foot of the footrest 11 can be raised while the railroad engineer is sitting on the cockpit 10. [ The foot plate 11 may have a buried groove 11a.

When the lower portion of the case body 111 is received in the embedding groove 11a of the foot plate 11, the flange 112 is placed on the periphery of the embedding groove 11a. In this state, when the bolts 113 are fastened to the thread grooves 11b around the embedding groove 11a through the fastening holes 112a of the flange 112, the case 110 is embedded in the foot plate 11 As shown in Fig. Here, the bolt 113 may be formed of a plate head bolt having a plate-like head. Therefore, the bolt 113 may not protrude from the gasket 120 in a state where the gasket 120 and the flange 112 are fastened to the footplate 11. [

The gasket 120 covers the upper surface of the flange 112. When the flange 112 is formed into a square ring shape, the gasket 120 may have the same size as the flange 112 and may have a rectangular ring shape. The gasket 120 may have a uniform thickness. The gasket 120 may be made of a polyethylene (PE) material or the like.

The gasket 120 can insulate the case body 111 and alleviate the impact applied to the case body 111. [ The gasket 120 has fastening holes 120a corresponding to the fastening holes 112a of the flange 112. The gasket 120 may be fixed together with the flange 112 by bolts 113 fastened through the fastening holes 120a.

The gasket 120 may be provided with a position identification lamp 126. The position identification lamp 126 illuminates the upper portion of the gasket 120 so that the position of the heating mechanism 100 can be identified to the railway engineer. The position identification lamps 126 may be disposed on the left and right sides of the gasket 120, respectively. The gasket 120 may be formed by recessing the mounting groove 127 from the upper surface. The position identification lamp 126 may be received in the mounting groove 127.

The position identification lamp 126 may be an LED module. The LED module is configured by mounting an LED on a circuit board. The LED may be an LED that emits white light. The semitransparent member 128 can close the mounting groove 127 to protect the position identification lamp 126 while the position identification lamp 126 is accommodated in the mounting recess 127. [ The translucent member 128 may be made of a material such as acrylic having a brown color.

The heating tubes 130 are arranged in the case body 111 so as to extend in the lateral direction. The heating tubes 130 have the same shape and can be arranged in the front-rear direction. The heating tubes 130 generate heat as the power is applied. The heating tube 130 may have a cylindrical shape. Although the heating tubes 130 are illustrated as being provided in two, one or three or more heating tubes 130 may be provided.

In one example, the heating tube 130 may be a sheath heater. The sheath heater is a tubular heating element with a heating coil embedded in a metal protection tube and a magnesium oxide as an insulating powder, filling the heating wire and the metal protection tube.

The heating tube 130 may have left and right terminals 131a and 131b at left and right ends. The left terminals 131a of the heating tubes 130 may be electrically connected by the left connector 132a. The nuts 133 are screwed to the left terminals 131a of the heating tubes 130 with both ends of the left connector 132a sandwiching the left terminals 131a of the heating tubes 130. [ Accordingly, the left connector 132a can be fixedly connected to the left terminals 131a of the heating tubes 130. [

The right terminals 131b of the heating tubes 130 can be electrically connected by the right connector 132b. The right connector 132b can be fixedly connected to the right terminals 131b of the heating tubes 130 in the same manner as the left connector 132a. The left and right connectors 132a and 132b are made of a conductive metal material. The left and right connectors 132a and 132b are connected to the power supply terminal 21 and the ground terminal 22 of the DC power source 20 (see FIG. 7), respectively, so that the heating tubes 130 can be connected in parallel.

As another example, the heating tube 130 may be made of a PTC heater (positive temperature coefficient heater). A PTC heater is a heating element whose principle is that the resistance increases when the temperature becomes too high, the temperature is lowered by decreasing the amount of current, the resistance is lowered and the amount of current is increased when the temperature is lowered.

The PTC heater can be composed of a mixture of conductive polymer and insulator made of 600 mesh to 15,000 mesh nanoparticles. The conductive polymer may be composed of a mixture of carbon and graphite, and the insulator may be composed of a mixture of mica and magnesium. When the heating tube 130 is made of a PTC heater, the overheating prevention sensor 196 to be described later may be omitted.

The heat dissipation panel 140 is accommodated in the case body 111. The heat dissipation panel 140 has an insertion hole 140a through which the left and right ends of the heating tube 130 are drawn while the heating tube 130 is inserted into the lower portion. The heat dissipation panel 140 has the same number of protruding blocks 141 as the number of the heating tubes 130 at the bottom. The protruding blocks 141 extend in the left-right direction and are arranged in the front-rear direction. The insertion holes 140a may be formed in the protruding blocks 141, respectively.

When the heating tube 130 has a cylindrical shape, the insertion hole 140a may have a circular cross-section. The insertion hole 140a may have a diameter larger than the diameter of the heating tube 130. [ Therefore, the outer circumferential surface of the heating tube 130 can be spaced from the inner circumferential surface of the insertion hole 140a. The heat dissipation panel 140 has a lateral width that is shorter than the lateral width in the case body 111.

The heat dissipation panel 140 accumulates the heat generated from the heating tube 130 and radiates the far infrared ray heat. The heat dissipation panel 140 accumulates heat generated from the heating tube 130 for a long time, thereby reducing power consumption. In addition, the far-infrared ray emitted from the heat dissipation panel 140 can be radiated to the railway engineer without a separate blower, and the body temperature of the railway engineer can be comfortably increased even with a relatively small amount of heat. In addition, since the far infrared ray heat does not adversely affect the paper even at a high temperature, a fire can be prevented.

The heat dissipation panel 140 may include a panel base made of aluminum or the like and a heat dissipation coating layer coated on the surface of the panel base with a mineral. The heat-radiating coating layer may be composed of montmorillonite or illite consisting of nanoparticles of 1,000 mesh to 10,000 mesh, and a mixture of kaolin, gin tin, and an adhesive. Waveguide grooves 142 may be formed on the upper surface of the heat dissipation panel 140 in the front-rear direction to increase the heat dissipation area.

The packing materials 150 pack the front and rear ends of the heat dissipation panel 140 with respect to the case body 111. For example, the packing materials 150 have substantially the same length as the front and rear end lengths of the heat dissipation panel 140, and have grooves 150a formed at the center thereof in the lateral direction. That is, the packing material 150 may have a cross-section of a 'D' shape. The packing materials 150 are brought into close contact with the inner wall of the case body 111 with the front and rear ends of the heat dissipating panel 140 sandwiched between the grooves 150a, 111).

The packing materials 150 prevent foreign matter from penetrating between the heat dissipation panel 140 and the case body 111 and insulate the heat dissipation panel 140 from the case body 111. The heat dissipation panel 140 and the case body 111 are made of, Thereby reducing the impact on the vehicle. The packing material 150 may be made of a material having heat resistance. For example, the packing material 150 may be made of a material such as silicon having a heat-resistant temperature of 320 ° C.

The support mechanism 160 supports the left and right ends of the heating tube 130 to the case body 111. For example, support mechanism 160 may include insulation tube caps 161, support brackets 162, insulation washers 163, and springs 164.

The insulating tube caps 161 penetrate the left and right ends of the heating tube 130. Each end portion 161a has a smaller cross sectional area than the central portion 161b and is fitted into the insertion hole 140a, And the other end portion 161c has a larger cross-sectional area than each central portion 161b. The insulating tube caps 161 maintain the state that the outer circumferential surface of the heating tube 130 is spaced from the inner circumferential surface of the insertion hole 140a while the heating tube 130 is inserted into the insertion hole 140a, 130 can be insulated from the heat dissipation panel 140. In addition, the insulating tube caps 161 can insulate the heating tube 130 from the support brackets 162. [ The space between the outer circumferential surface of the heating tube 130 and the inner circumferential surface of the insertion hole 140a may be filled with an insulating material.

The center portion 161b of the insulation tube cap 161 may be a hollow cylindrical shape. The one end portion 161a of the insulating tube cap 161 may be a hollow cylindrical body having an outer diameter smaller than the center portion 161b of the insulating tube cap 161. [ The other end portion 161c of the insulating tube cap 161 may be a hollow cylindrical body having an outer diameter larger than the central portion 161b of the insulating tube cap 161. [ The inner diameter of the insulating tube cap 161 may be set equal to the outer diameter of the heating tube 130. The insulating tube cap 161 may be made of a ceramic material such as alumina.

The support brackets 162 are respectively disposed on the left and right sides of the heat dissipation panel 140 and fixed within the case body 111. The support brackets 162 support the respective other end portions 161c of the insulation tube caps 161 while sandwiching the respective central portions 161b of the insulation tube caps 161. The left support bracket 162 supports the insulation tube caps 161 fitted in the left ends of the heating tubes 130, respectively, in the holes. The right support bracket 162 supports the insulation tube caps 161 fitted in the right ends of the heating tubes 130, respectively, in the holes.

The support bracket 162 may be configured such that a horizontal plate 162b is connected to the lower end of the vertical plate 162a. The vertical plate 162a has holes for inserting the insulating tube caps 161, respectively. The horizontal plate 162b can be fastened to the case body 111 by bolts while being in contact with the bottom surface of the case body 111. [ The support bracket 162 may be made of cold-rolled steel and then surface-treated by heat-resistant powder coating.

The insulating washer 163 is disposed on the opposite side of the other end portion 161c of the insulating tube caps 161 with the support brackets 162 therebetween and sandwiches the respective central portions 161b of the insulating tube caps 161 . The insulating washer 163 can insulate the spring 164, which is in contact with the heat dissipating panel 140, against the support bracket 162. The insulating washer 163 may be made of a ceramic material such as alumina.

The springs 164 support the left and right ends of the heat dissipation panel 140 with elastic force against the insulating washers 163, respectively. The spring 164 may be a compression coil spring. The spring 164 is disposed such that both ends of the spring 164 are in contact with the insulating washer 163 and the heat dissipating panel 140 with the insulating tube cap 161 fitted in the center. Here, the spring 164 may be disposed in a compressed state between the insulating washer 163 and the heat dissipating panel 140. The spring 164 functions to mitigate the shock applied to the heat dissipation panel 140 and the heating tube 130.

The covers 170 cover the upper opening areas located on the left and right sides of the heat radiation panel 140 in the upper opening area of the case body 111, respectively. The covers 170 may each be formed in the same shape. The cover 170 has a hexahedron-like appearance and has a uniform thickness, so that it can have a hexahedral internal space.

The cover 170 may be opened to the side and the bottom adjacent to the heat dissipation panel 140. The cover 170 may be formed such that the upper surface of the cover 170 has the same height as the upper surface of the gasket 120 and the lower end of the cover 170 abuts against the bottom surface of the case body 111. The cover 170 can be fastened to the case body 111 by bolts in a state where the side surfaces thereof are in contact with the inner wall of the case body 111. The cover 170 may be made of a cold-rolled steel sheet and then surface-treated by heat-resistant powder coating.

The reflection plate 181 is disposed below the heat dissipation panel 140 and is housed in the case body 111. The reflection plate 181 reflects the heat radiated from the heat dissipation panel 140 upward, thereby preventing the heat radiated from the heat dissipation panel 140 from escaping to the rear, thereby enhancing the heat dissipation effect. The reflection plate 181 may be made of stainless steel or the like. The reflection plate 181 is polished to face the heat dissipation panel 140 to have reflection characteristics.

The reflector 181 includes first extensions 181a extending upwardly and backwardly from the front and rear ends thereof and second extensions 181b extending horizontally from the first extensions 181a, 181b, and third extensions 181c that extend downwardly from the second extensions 181b, respectively. The third extensions 181c of the reflector 181 can be held in contact with the inner wall of the case body 111. [

The heat insulating material 186 is disposed on the lower side of the reflection plate 181 and is housed in the case body 111. The heat insulating material 186 prevents heat transfer between the reflection plate 181 and the case body 111 and allows the heat insulating material 186 to be insulated. The heat insulating material 186 may be formed in a plate shape having a uniform thickness. The heat insulating material 186 may have the same size as the bottom surface size of the case body 111. The heat insulating material 186 may be one produced by continuously laminating mica-based ceramic silica and fibers made by melting alumina. Here, the heat insulating material 186 has a packing density of 96 kg / m 3 and a heat-resistant temperature of 1260 ° C.

The heating mechanism 100 for the train cockpit described above is embedded in the footstool 11 of the cockpit 10 and radiates the far infrared ray during the winter train operation so that the lower portion of the cockpit 10 can be efficiently heated by the far- have. Thus, the railway engineer can control the train in a comfortable environment.

7, the heating temperature of the heating tubes 130 may be adjusted to a high temperature or a low temperature by a temperature controller. The temperature controller allows power to be applied to one or two of the two heating tubes 130 according to the user's operation to adjust the temperature. The temperature regulator may include a selection switch 191 and a relay 192.

The selection switch allows the user to select the rest mode, the low temperature mode, and the high temperature mode according to the user's operation. The selection switch 191 may be disposed at the top of the cockpit 10. The selection switch 191 includes first, second, and third switches 191a, 191b, and 191c. The first, second and third switches 191a, 191b and 191c and the relay 192 constitute a circuit together with the DC power source 20 and the heating tube 130.

When the user operates the selection switch 191 to select the rest mode, the first switch 191a is turned off. Therefore, all of the two heating tubes 130 are not supplied with power.

When the user selects the low temperature mode by operating the selection switch 191, the first switch 191a is turned on and the second switch 191b is turned on. At this time, since the third switch 191c is in an off state, only one heating tube 130 can receive power and generate heat.

When the user selects the high temperature mode by operating the selection switch 191, the first switch 191a is turned on, the second switch 191b is turned on, the relay 192 is activated, and the relay contact 192a is turned on do. Therefore, all of the two heating tubes 130 can receive power and generate heat.

When the second switch 191b is turned on according to the selection of the low temperature mode, the first lamp 194a can emit light. When the third switch 191c is turned on according to the selection of the high temperature mode, the second lamp 194b can emit light. The first and second lamps 194a and 194b may emit light of different colors. The first and second lamps 194a and 194b may each be an LED.

The overheat prevention sensor 196 cuts off the power supplied to the heating tubes 130 when the temperature of the heat dissipation panel 140 is sensed to exceed the set temperature, for example, 50 占 폚. The overheat prevention sensor 196 is disposed on the side of the heat dissipation panel 140 and may be circuitly connected to open and close the power supply line between the power supply stage 21 and the first switch 191a. The overheat prevention sensor 196 may be a bimetallic thermal protector or the like.
