Among these amenities, there are cold dampers for cars that cool drinks in summer and warm drinks in winter.

Conventional vehicle cold and cold storage used a method of cooling or heating the storage container by forming a thermoelectric element in the storage container of the vehicle cold and cold storage. However, when only the thermoelectric element is used to cool or heat the storage container, there is a limit to the range in which the temperature of the storage container can be changed for a predetermined unit time. That is, when only the thermoelectric element is used to cool or heat the storage container, there is a limit to the temperature at which the storage container can be cooled and the temperature at which it can be heated. It will take a lot of time.

In addition, the bottom shape of a storage container of a conventional cold storage cabinet for vehicles is manufactured in a shape that results in a loss of thermal efficiency. That is, as shown in Figure 1, since the storage container 10 of the conventional vehicle cold and cold storage bin is formed in a rounded (rounded) corner portion of the bottom surface (rounding), the thermoelectric element 12 on the back of the storage container 10 ), The thermoelectric element 12 is formed at a predetermined height h from the lower end of the storage container 10.

In this case, there is a problem that the manufacturing process of the cold storage for vehicles is complicated.

In addition, since the first heat conductive block 21 is welded and bonded to the rear surface of the storage container 20, it is difficult to bring the storage container 20 and the first heat conductive block 21 into close contact with each other, and heat generated by the thermoelectric element 23 is obtained. Is transferred to the storage container 20, there is a problem that heat loss occurs in the seam portion of the storage container 20 and the first heat conductive block 21.

An embodiment of the present invention is to provide a cold storage device for a vehicle that can quickly cool or heat the storage stored in the storage container.

In addition, the cold storage apparatus for a vehicle may be installed in, for example, the console box of the front seat or the rear armrest of the vehicle, but is not limited thereto, and other positions (for example, a glove box, a door pocket, It may also be installed in a panel on the front of the vehicle. Here, only the case where the cold storage device for a vehicle is applied to the armrest is shown as an example, the shape may be variously modified when the cold storage device for the vehicle is applied to other locations in the vehicle.

Referring to FIG. 3, the cold storage apparatus 100 for a vehicle may include a storage container 102, a cover 104, an auxiliary storage unit 106, a first heat conductive member 108, a thermoelectric element 110, and a heat dissipation unit ( 112).

The storage container 102 has a storage space of a predetermined shape therein and is open at the top. In this case, the storage container 102 can store articles such as, for example, water bottles, drinks, and the like. The storage container 102 may be made of a thermally conductive metallic material. In addition, a sterilization and sterilization device (not shown) for generating negative ions or the like may be formed in the storage container 102.

A cover 104 is formed on top of the storage container 102. At this time, one side of the cover 104 may be hinged to the storage container 102 so as to be rotatable. In this case, the cover 104 can be opened and closed. When the cover 104 is opened, the upper part of the storage container 102 is opened, and when the cover 104 is closed, the storage container 102 is sealed. In addition, the other side of the cover 104 can be hooked to the storage container 102. In this case, when the cover 104 is closed, the cover 104 is firmly engaged with the storage container 102, so that the storage container 102 can be surely sealed.

On the other hand, the cold storage apparatus 100 for a vehicle may be configured as a double cover cover. That is, a cover 121 serving as a cup holder can be formed inside the cover 104. At least one first accommodating hole 123 capable of accommodating the cup may be formed in the cup holder combined cover 121. The cup holder combination cover 121 can be hinged to the cover 104 or the storage container 102 so that one side is rotatable. The cup holder combination cover 121 may be opened and closed together with the cover 104 and may be independently opened and closed separately from the cover 104. [

For example, as shown in FIG. 4, when the user wants to remove a water bottle from the storage container 102, the cover 102 and the cup holder cover 121 are opened together to open the upper portion of the storage container 102 After the water bottle can be removed.

As shown in FIG. 5, when the user wants to store the cup, the cup may be stored in the first storage hole 123 of the cup holder combined cover 121 with only the cover 102 opened. . In this case, the user seated in the seat in which the cold storage apparatus 100 for the vehicle is installed can be safely stored without shaking the cup used by the user using the cup holder combined cover 121. In particular, since there is no place to store a cup in the rear seat of a general vehicle, when the cold / cold storage device 100 having a cup holder cover 121 is installed in the rear seat of a vehicle, the person sitting in the rear seat may also You will be able to safely store this used cup.

The auxiliary storage portion 106 is formed in front of the storage container 102. Specifically, the front of the storage container 102 may be formed with a display unit 125 for displaying the operating state and temperature of the cold storage apparatus 100 for vehicles, the auxiliary storage unit 106 is the display unit 125 It may be formed in the space below. In this case, the space efficiency of the on-vehicle cold storage device 100 can be improved.

The auxiliary storage portion 106 may be formed in a structure that can be opened and closed like a drawer. The cup holder plate 127 may be formed in the auxiliary storage unit 106 to store the cup. The cup holder plate 127 may be stored in the auxiliary storage unit 106 when the auxiliary storage unit 106 is closed. After being in the closed state, it comes out when the auxiliary storage unit 106 is opened. At this time, the auxiliary storage part 106 may be connected to the storage container 102 through a separate heat conductive member (not shown). A detailed description thereof will be described later with reference to FIGS. 11 and 12.

The first heat conductive member 108 is provided on the outer surface of the storage container 102. At this time, the first thermally conductive member 108 may be formed with one side connected to the thermoelectric element 110. In this case, the first thermally conductive member 108 serves to transmit the heat generated from the thermoelectric element 110 (in this case, the heat may be a high temperature of 0 ° C or higher and a low temperature of less than 0 ° C) to the storage container 102 .

The first thermally conductive member 108 is made of a material or a product having an excellent thermal conduction efficiency. For example, a heat pipe may be used as the first heat conduction member 108. When a heat pipe is used as the first heat conduction member 108, at least one first heat conduction member 108 may be installed on the outer surface of the storage container 102, And may be formed in a U-shape across the back, the lower surface, and the entire surface of the substrate 102. In this case, by widening the area in which the first heat conductive member 108 contacts the storage container 102, heat generated in the thermoelectric element 110 may be quickly transferred to the storage container 102, and the inside of the storage container 102 may be increased. By uniformly adjusting the temperature of the storage container 102 it is possible to prevent the temperature difference occurs depending on the place. However, the shape of the first heat conduction member 108 is not limited to the U-shape, but may be formed in various other shapes.

Here, the first thermally conductive member 108 is described as being formed between the storage container 102 and the thermoelectric element 110. However, the present invention is not limited thereto, and the thermoelectric element 110 may be in direct contact with the storage container 102 It is possible. Although the first thermally conductive member 108 is described as being in contact with the thermoelectric element 110, the first thermally conductive member 108 is not limited to being in contact with the thermoelectric element 110, (Not shown). For example, the first thermally conductive member 108 can be installed on the lower surface of the storage container 102, in which case the first thermally conductive member 108 is transferred from the thermoelectric element 110 to the storage container 102 Thereby facilitating faster movement of the heat in the storage container 102.

The thermoelectric element 110 refers to a device capable of converting electrical energy into thermal energy and thermal energy into electrical energy. Here, the electrical energy is converted into thermal energy through the thermoelectric element 110, in which case cooling or heating is possible through the thermoelectric element 110 according to the polarity of the power applied to the thermoelectric element 110.

For example, in hot weather such as summer, the front surface of the thermoelectric element 110 (that is, the surface in contact with the first thermal conductive member 108) absorbs heat, and the rear surface of the thermoelectric element 110 (that is, the heat sink). Power to the thermoelectric element 110 to radiate heat from the surface in contact with the surface 128, and in this case, the storage container 102 is cooled by the thermoelectric element 110 to cool the storage device 100 for a vehicle. Can be used as a refrigerator.

In cold weather like winter, heat is emitted from the front surface of the thermoelectric element 110 (that is, the surface in contact with the first thermally conductive member 108) by reversing the polarity of the power source applied to the thermoelectric element 110, It is possible to absorb heat at the back surface of the thermoelectric element 110 (i.e., the surface in contact with the heat sink 128). In this case, the storage container 102 is heated through the thermoelectric element 110 to use the cold storage device 100 for a vehicle as a warmer.

The heat dissipation unit 112 is installed on the rear surface of the thermoelectric element 110 to absorb and release heat generated from the thermoelectric element 110. In addition, the heat dissipation unit 112 functions to absorb heat around the thermoelectric element 110. That is, the heat dissipation unit 112 functions to absorb and release heat generated by the thermoelectric element 110 when the thermoelectric element 110 cools the storage container 102, and the thermoelectric element 110 stores the storage container. When the 102 is heated, it functions to absorb surrounding heat and transfer it to the thermoelectric element 110.

The heat radiating portion 112 may include a heat sink 128 and a radiating fin 129. Here, the heat sink 128 may be installed, for example, on the back surface of the thermoelectric element 110, and the heat radiating fin 129 may be installed on the rear side of the heat sink 128. The heat sink 128 and the radiating fin 129 are made of a material having a high thermal conductivity to quickly and efficiently absorb or discharge heat. At this time, the radiating fins 129 may have a plurality of plate-like layers laminated to widen the heat radiation area.

Meanwhile, the cold storage apparatus 100 for a vehicle cools the storage container 102 using not only the thermoelectric element 110 but also a cooling device (for example, an air conditioner) and a heating device (for example, a heater) installed in the vehicle. Or heating. That is, when the cooling device (not shown) in the vehicle is operated, the storage container 102 may be cooled by using the thermoelectric element 110 and the cooling device (not shown). When the heating device (not shown) in the vehicle is operated, the storage container 102 may be heated using the thermoelectric element 110 and the heating device (not shown). Hereinafter, the cooling device and heating device in a vehicle are called air conditioning devices.

6 is a perspective view showing the internal configuration of the cold storage apparatus for a vehicle according to an embodiment of the present invention, Figure 7 is an exploded perspective view showing the internal configuration of a cold storage apparatus for a vehicle according to an embodiment of the present invention. For convenience of description, the first heat transfer member is omitted here.

6 and 7, the storage container housing 114 is formed outside the storage container 102. The storage container 102 is housed in the storage container housing 114 and is spaced apart from the storage container housing 114 by a predetermined distance. Here, the storage container 102 and the storage container housing 114 form a storage unit of the cold storage apparatus 100 for a vehicle.

At least one heat dissipation fin 131 is formed on an outer circumferential surface of the storage container 102. For example, the heat dissipation fin 131 may be formed to protrude along the outer circumferential surface of the storage container 102 at the upper and lower ends of the outer circumferential surface of the storage container 102, respectively. At this time, the end of each of the heat radiation fins 131 may be formed in close contact with the storage container housing 114. In this case, a gas movement passage is formed between the storage container 102 and the storage container housing 114 by heat dissipation fins 131 formed at the upper and lower ends of the outer circumferential surface of the storage container 102.

The gas inlet 116 is formed at one side of the storage container housing 114. The gas inlet 116 includes a first gas inlet 116-1 and a second gas inlet 116-2. One side of the first gas inlet 116-1 is formed to correspond to the storage container 102, and the other side of the first gas inlet 116-1 is connected to a discharge part (not shown) of the air conditioning apparatus. One side of the second gas inlet 116-2 is formed to correspond to the heat dissipation unit 112, and the other side of the second gas inlet 116-2 is connected to a discharge unit (not shown) of the air conditioning unit.

The other side of the reservoir housing 114 is formed with a gas outlet 118. The gas discharge part 118 includes a first gas discharge part 118-1 and a second gas discharge part 118-2. One side of the first gas discharge part 118-1 is formed to correspond to the storage container 102, and the other side of the first gas discharge part 118-1 is connected to a recovery part (not shown) of the air conditioning apparatus. One side of the second gas discharge unit 118-2 is formed to correspond to the heat dissipation unit 112, and the other side of the second gas discharge unit 118-2 is connected to a recovery unit (not shown) of the air conditioner.

The cold storage apparatus 100 for a vehicle may include an opening and closing control unit (not shown) that may open and close the internal passages of the gas inlet 116 and the gas outlet 118. In this case, when the air conditioner in the vehicle is operated, the vehicle cold / cold storage device 100 may open the internal passages of the gas inlet 116 and the gas outlet 118 through an opening and closing control unit (not shown). In addition, when the air conditioner in the vehicle is not operated, the vehicle cold / cold storage device 100 may close the internal passages of the gas inlet 116 and the gas outlet 118 through an opening and closing control unit (not shown). .

In the cold and cold vehicle apparatus 100 configured as described above, in a hot weather such as summer, absorbs heat from the front surface of the thermoelectric element 110, and releases heat from the rear surface of the thermoelectric element 110 to open the storage container 102. Can be cooled. At this time, when the air conditioner of the vehicle heating and cooling device is operated, the vehicle cold storage device 100 opens the inner passage of the gas inlet 116 through the opening and closing control unit (not shown) to discharge the discharge unit (not shown) Allow cold air to flow from

Here, the cold air flowing into the first gas inlet 116-1 of the gas inlet 116 supplies cold air to the storage container 102 while moving along the gas flow passage formed by the heat dissipation fin 131, and then supplies the cold air to the first container. It is discharged through the gas discharge part 118-1. In this case, not only the storage container 102 may be cooled through the thermoelectric element 110, but the storage container 102 may be cooled by cold air generated in a cooling device. Thus, the storage container may be used using only the thermoelectric element 110. Compared with the case where the 102 is cooled, the storage container 102 can be cooled efficiently. That is, when the thermoelectric element 110 and the cooling device are used at the same time, the storage container 102 can be cooled to a predetermined temperature in a short time.

The cold air introduced into the second gas inlet 116-2 of the gas inlet 116 is heat-exchanged in the heat dissipating unit 112 and discharged through the second gas outlet 118-2. In this case, since the cool air generated in the cooling device is supplied to the heat dissipation unit 112 through the second gas inlet 116-2, the heat dissipation efficiency of the heat dissipation unit 112 may be improved, and thus the thermoelectric element ( It is possible to improve the cooling efficiency of 110).

When the cooling device of the vehicle's air conditioning unit is operated, the vehicle cold storage apparatus 100 opens the internal passage of the gas discharge unit 118 through an opening and closing control unit (not shown). Then, the cold air discharged to the first gas discharge unit 118-1 is recovered to the air conditioning unit through a recovery unit (not shown) of the air conditioning unit, and the heat exchanged cold air discharged to the second gas discharge unit 118-2. Is recovered to the air conditioning unit through a recovery unit (not shown) of the air conditioning unit.

In addition, in cold weather such as winter, heat may be emitted from the front surface of the thermoelectric element 110, and heat may be absorbed from the rear surface of the thermoelectric element 110 to heat the storage container 102. At this time, when the heating device of the heating and cooling device of the vehicle is operated, the vehicle cold and refrigerator apparatus 100 opens the inner passage of the gas inlet 116 through an opening and closing control unit (not shown) to discharge the discharge unit (not shown) Allow warmth to flow from

Here, the warm air introduced into the first gas inlet 116-1 of the gas inlet 116 moves along the gas flow passage formed by the heat dissipation fin 131 to supply warmth to the storage container 102, and then to supply the warmth to the first container. It is discharged through the gas discharge part 118-1. In this case, since the storage container 102 can be heated not only by the thermoelectric element 110 but also by the warmth generated by the heating device, the storage container using only the thermoelectric element 110. As compared with the case where the 102 is heated, the storage container 102 can be heated efficiently. That is, when the thermoelectric element 110 and the heating device are used at the same time, the storage container 102 can be heated to a predetermined temperature in a short time.

The warm air introduced into the second gas inlet 116-2 of the gas inlet 116 is heat-exchanged in the heat radiating unit 112 and is discharged through the second gas outlet 118-2. In this case, since the warm air generated by the heating device through the second gas inlet 116-2 flows into the heat dissipation unit 112 to supply heat to the heat dissipation unit 112, the heating efficiency of the thermoelectric element 110 is increased. It can be improved.

Here, the cold air or warm air introduced through the first gas inlet 116-1 is discharged through the first gas outlet 118-1, and the cold air introduced through the second gas inlet 116-2. Or it is shown that the warmth is discharged through the second gas discharge unit 118-2, but is not limited to this, the cold storage apparatus 100 for a vehicle is the first gas discharge unit 118-1 and the second gas discharge. It may be implemented without the portion 118-2. In this case, the cold air or warm air introduced through the first gas inlet 116-1 may be discharged to the rear of the heat dissipating unit 112 while moving the gas movement passage. In addition, the cold air or warm air introduced through the second gas inlet 116-2 may be heat exchanged in the heat radiating unit 112, and then discharged to the rear of the heat radiating unit 112.

In addition, although one side of the first gas inlet 116-1 is illustrated as being connected to the storage container housing 114, the present invention is not limited thereto, and one side of the first gas inlet 116-1 may be the storage container housing. It may be connected to the storage container 102 through 114. In this case, cold air or warm air flows directly into the storage container 102 from the discharge part (not shown) of the air conditioning and heating device. Then, the object accommodated in the storage container 102 can be directly cooled or heated with cold air or warmth of the air conditioning apparatus. In this case, one side of the first gas discharge part 118-1 may also be connected to the storage container 102 through the storage container housing 114.

In addition, one side of one gas inlet is connected to the storage container housing 114 to allow the cold or warm air of the air conditioning unit to cool or heat the storage container 102 while moving the gas movement passage, and another gas inlet. One side of the portion may be connected to the storage container 102 through the storage container housing 114 to directly cool or heat an object stored in the storage container 102.

When the heating device is operated among the heating and cooling devices of the vehicle, the vehicle cold storage apparatus 100 opens the internal passage of the gas discharge unit 118 through an opening and closing control unit (not shown). Then, the warm air discharged to the first gas discharge unit 118-1 is recovered to the air conditioning unit through a recovery unit (not shown) of the air conditioning unit, and the heat exchanged warmer discharged to the second gas discharge unit 118-2. Is recovered to the air conditioning unit through a recovery unit (not shown) of the air conditioning unit.

On the other hand, if the heating and cooling device does not operate while the thermoelectric element 110 cools or heats the storage container 102, the vehicle cold / cold storage device 100 is the gas inlet 116 through the opening and closing control unit (not shown) ) And the inner passage of the gas outlet 118 may be closed to block the storage container 102 from the outside. In this case, by blocking the storage container 102 from the outside, the cooling efficiency and the heating efficiency of the storage container 102 can be prevented from being lowered.

In this case, when the vehicle air conditioning apparatus is operated, the vehicle cold storage apparatus 100 opens both the internal passages of the first gas inlet 116-1 and the second gas inlet 116-2, and the first Although illustrated as opening both the internal passages of the gas discharge unit 118-1 and the second gas discharge unit 118-2, the present invention is not limited thereto, and the cold storage apparatus 100 for the vehicle may include the first gas inlet unit 116-. The inner passage of any one of 1) and the second gas inlet 116-2 is opened, and the inner passage of any one of the first gas outlet 118-1 and the second gas outlet 118-2. You can also open it.

For example, when the air conditioner of the vehicle is operated, the vehicle cold storage apparatus 100 opens the inner passage of the first gas inlet 116-1, and the interior of the first gas outlet 118-1. When the passage is opened, cold air or warm air flows into the first gas inlet 116-1 from the discharge unit (not shown) of the air conditioner, and supplies cold air or warm air to the storage container 102, and then the first gas outlet. Discharged to (118-1).

When the air conditioner of the vehicle is operated, the vehicle cold / cold storage device 100 opens the inner passage of the second gas inlet 116-2 and opens the inner passage of the second gas outlet 118-2. When opened, cold air or warm air flows into the second gas inlet 116-2 from the discharge unit (not shown) of the air conditioner, supplies cold air or warm air to the heat radiating unit 112, and then discharges the second gas outlet 118. -2) will be discharged.
