The present invention relates to a cold storage cabinet for a vehicle, and more particularly, having two or more storage compartments capable of controlling individual temperatures so that refrigeration and heating can be performed simultaneously, and a working system such as welding is unnecessary by configuring a cooling system using a thermoelectric element. At the same time, the present invention relates to a cold and cold refrigerator for a vehicle that is simple in structure and can solve problems such as environmental pollution.

In general, the refrigerator is configured to supply the cool air generated in the evaporator of the refrigeration cycle to the storage compartment in the cabinet to maintain the freshness of various foods for a long time. However, such a refrigerator may perform only a refrigerating and refrigerating function, and many components such as a condenser, an evaporator, and a compressor are required to achieve a refrigeration cycle.

In order to solve this problem, recently, a cold / cold refrigerator has been devised that can simultaneously heat and cool using a thermoelectric element.

Hereinafter, with reference to the accompanying drawings it will be described a conventional cold and cold storage for vehicles.

1 is an exploded perspective view of a conventional cold storage for a vehicle.

As shown in FIG. 1, a conventional cold storage cabinet for a vehicle includes a cabinet-shaped cabinet 10 having storage spaces 21 and 22 formed therein for storing food, and a storage space that is hinged to the cabinet 10. It is comprised so that the door 50 which opens and closes 21 and 22 may be provided.

The cabinet 10 has an inner case 11 for forming the storage spaces 21 and 22 with the front portion open, and a thermoelectric element disposed on the rear wall of the inner case 11 and capable of performing heat and endothermic functions on its own. Elements 41 and 42 and an outer case 12 coupled to surround the inner case 11 are included.

In addition, the storage space in the cabinet 10 is divided into a first storage chamber 21 and a second storage chamber 22. The first storage chamber 21 and the second storage chamber 22 are divided up and down by a middle plate 30 of a rectangular plate having a predetermined thickness, so that the refrigerating and warming functions can be performed simultaneously or separately. to be. That is, the first storage compartment 21 and the second storage compartment 22 partitioned up and down can be used for the same purpose, and can be used differently as a refrigerating compartment and a heating compartment or, conversely, a heating compartment and a refrigerating compartment. In addition, the intermediate partition 30 is detachably assembled from the cabinet 10, which is to remove the first storage chamber 21 and the second storage chamber 22 when they are used for the same purpose, so as to effectively use the storage space. . To this end, a pair of rails 31 are symmetrically provided on both side walls of the inner case 11 so that both side ends 30L and 30R of the intermediate partition 30 slide together. Therefore, when the intermediate partition 30 is installed in the horizontal direction along the pair of rails 31, the storage space is partitioned vertically into the first storage chamber 21 and the second storage chamber 22, and the intermediate partition 30 is a shelf. You will be able to perform the function.

The thermoelectric elements 41 and 42 are Peltier elements in which one side is cooled by the semiconductor carrier and the other side is heated when a current flows through the semiconductor (or conductor). The first storage chamber 21 is used according to the applied current direction. The second storage compartment 22 is installed in close contact with the inner case 11 so as to easily change the temperature. The thermoelectric element includes a first thermoelectric element 41 disposed on the rear wall of the first storage chamber 21 and a second thermoelectric element 42 disposed on the rear wall of the second storage chamber 22. Accordingly, when the current directions applied to the first thermoelectric element 41 and the second thermoelectric element 42 are different, the first storage chamber 21 and the second storage chamber 22 have different uses (refrigeration chamber, warm room, or warm room). The first storage chamber 21 and the second storage chamber 22 are configured to be used for the same purpose (both a warm room or a refrigerator).

At this time, the user controls the thermoelectric elements 41 and 42 by operating the control panel 13 disposed on the upper surface of the cabinet 10 to adjust the temperatures of the storage spaces 21 and 22.

However, the conventional cold and cold refrigerator for a vehicle has a disadvantage in that cooling and heating efficiency is low because heat generated from the thermoelectric elements 41 and 42 is conducted to the inner case 11 and then radiated into the storage compartments 21 and 22. . At this time, in order to increase the capacity of the thermoelectric elements (41, 42) in order to solve the above problems, there is a limit in the amount of power that can be supplied in the vehicle itself to increase the capacity of the thermoelectric elements (41, 42) There are many difficulties.

The present invention has been made to solve the above problems, the heat generated from the thermoelectric element can be more efficiently transferred to the interior of the storage compartment, to provide a cold and cold storage for vehicles configured to even the temperature distribution inside the storage compartment. There is a purpose.

The storage compartment is formed to be divided into a first storage compartment and a second storage compartment, and a first through hole and a second through hole are formed on one side of the first storage compartment and the second storage compartment, respectively, and the first through hole and the second through hole are independent of each other. The first thermoelectric element and the second thermoelectric element are configured to be capable of heating or cooling.

Cold storage for a vehicle according to the present invention is a heat sink coupled to the structure capable of heat transfer to one side of the thermoelectric element exposed to the interior of the storage compartment, and a circulation fan coupled to the heat sink to transfer the heat of the heat sink evenly into the storage compartment. It is further provided.

In addition, the heat sink is coupled to the structure capable of heat transfer to the other side of the thermoelectric element exposed to the outside of the main body, and a fan coupled to the heat sink to ventilate the heat of the heat sink to the outside is further provided.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

Figure 2 is an exploded perspective view of a cold compartment for a vehicle according to the present invention.

As shown in FIG. 2, in the cold storage apparatus for a vehicle according to the present invention, a first storage compartment 110 and a second storage compartment 120 are formed therein to enable storage of articles, and the interiors of the storage compartments 110 and 120 may be formed. A main body 100 having a first through hole 112 and a second through hole (not shown) formed on one side thereof to be exposed to the outside; A first thermoelectric element 210 and a second thermoelectric element (not shown) coupled to each through hole to generate cold or warm air; A first heat transfer block 212 and a second heat transfer block (not shown) coupled to be in contact with one side of each thermoelectric element exposed to the interior of the storage chambers 110 and 120; A first heat sink 310 and a second heat sink 320 coupled to one surface of each heat transfer block opposite to the thermoelectric element; A first circulation fan 410 and a second circulation fan 420 coupled to each of the heat sinks 310 and 320 to evenly transfer cold or warm air of the heat sinks 310 and 320 into the storage compartments 110 and 120. ; A first heat dissipation plate 510 and a second heat dissipation plate 520 coupled to contact the other side surfaces of the thermoelectric elements exposed to the outside of the main body 100; It is coupled to each of the heat sink (510, 520) is configured to include a first ventilation fan 610 and the second ventilation fan 620 for ventilating the cold or warm air of the heat sink (510, 520) to the outside.

In the main body 100, an opening is formed in an upper portion of the first storage chamber 110 and the second storage chamber 120, and the first cover 114 which opens and closes the opening of the first storage chamber 110 and the second storage chamber 120. ) And a second cover 124.

The thermoelectric element is configured in a structure capable of mutually independent operation to emit cold air or warmth according to the direction of the applied current, when the cold air is emitted from the thermoelectric element, the storage chambers 110 and 120 serve as a refrigerating chamber, When warmth is emitted from the thermoelectric element, the storage chambers 110 and 120 serve as a warming chamber. In this case, the on-vehicle refrigerator according to the present invention is preferably provided with a selection unit for controlling the operation of the thermoelectric element so that the user can independently select the function of each of the storage compartments (110, 120) to be heated or refrigerated, the selection unit It may be configured in various structures such as a control panel fixed to the main body 100 or a remote control separated from the main body 100.

The number of storage compartments 110 and 120 formed in the main body 100 is not limited to two as shown in FIG. 2 but may be integrated into one according to a user's selection, and may be changed to be formed in three or more.

In the present embodiment, the first thermoelectric element 210 is controlled to radiate cold air and the second thermoelectric element is controlled to radiate warmth, such that the first storage compartment 110 is used as a refrigerating compartment and the second storage compartment 120 is a storage compartment. Is utilized. However, in the cold storage for a vehicle according to the present invention, when the user controls the selector to control both the first thermoelectric element 210 and the second thermoelectric element to emit cold air, the first storage compartment 110 and the second storage compartment 120. All may be used as a refrigerating compartment, and when the first thermoelectric element 210 and the second thermoelectric element are controlled to radiate warmth, both the first storage chamber 110 and the second storage chamber 120 may be used as a heating chamber.

In addition, the circulation fan (410, 420) applied to the cold and cold storage for the vehicle according to the present invention, the storage compartment 110 in order to evenly transfer the cold and warm air delivered to the heat sink (310, 320) inside the storage compartment (110, 120). , 120) Since the internal air is sucked into the circulation fans 410 and 420 in front and discharged between the circulation fans 410 and 420 and the heat sinks 310 and 320, only one side of the thermoelectric element is located. The excessive heating or cooling does not occur and the temperature distribution inside the storage chambers 110 and 120 is uniformly formed. Therefore, there is an advantage that the article stored in the storage compartments 110 and 120 is heated or cooled in the same manner regardless of the loading position.

The structure and operation of the heat sinks 510 and 520 and the ventilation fans 610 and 620 coupled to the rear surface of the main body 100 will be described with reference to the following drawings.

3 is a cross-sectional view cut vertically to the portion where the first thermoelectric element is coupled, Figure 4 is a perspective view showing the back of the cold compartment for a vehicle according to the present invention.

As shown in FIG. 3, the cool air generated in the first thermoelectric element 210 is transferred to the first heat sink 310 via the first heat transfer block 212 and transferred to the first heat sink 310. The cold air is forcedly circulated into the first storage compartment 110 by the first circulation fan 410. At this time, since a plurality of first cooling fins 312 are formed in the first heat sink 310 of the side surface coupled with the first circulation fan 410, the first heat sink ( The air flowing toward 310 is cooled while passing through the space between the first cooling fins 312 and is discharged between the first circulation fan 410 and the first heat sink 310.

In this case, when the first cooling fins 312 are not formed on the first heat sink 310, the first circulation fan 410 and the first heat sink 310 are coupled to be spaced apart from each other by a predetermined interval or are coupled to each other. At least one flow path is formed in the site. Therefore, the air sucked by the first circulation fan 410 may be discharged between the first circulation fan 410 and the first heat sink 310.

Since the main body 100 is made of a heat insulating material to block heat transfer between the inside and the outside, and the first heat transfer block 212 is made of a material having a high heat transfer rate, the heat generated from the first thermoelectric element 210 is the main body 100. It is not conducted to the heat transfer through the first heat block 212 only to the heat sink (310, 320). Therefore, since the heat generated in the first thermoelectric element 210 is used only to cool the air inside the first storage chamber 110, the efficiency is remarkably improved. At this time, the first heat transfer block 212 is made of a material capable of heat conduction to transfer the heat generated from the first thermoelectric element 210 to the first heat sink 310, the air inside the first storage chamber (110). Is contacted to the inner surface of the first thermoelectric element 210 so as not to leak out of the main body 100 and coupled to the first through hole 112 in a fitting structure.

When the first thermoelectric element 210 is operated to cool the side facing the inner side of the main body 100, the side facing the outer side of the main body 100 is heated. Since the first heat sink 510 and the first ventilation fan 610 are sequentially coupled to the side surfaces of the first thermoelectric element 210 facing the outside of the main body 100, the first thermoelectric element ( Heat generated in the 210 is transferred to the first heat sink 510 and then leaked to the outside by the first ventilation fan 610.

As such, when the first heat sink 510 and the first ventilation fan 610 are further provided to cool the first thermoelectric element 210, the first thermoelectric element dissipates cold air toward the first storage chamber 110. The performance of 210 is further improved.

The process of heating the second storage chamber 120 by the second thermoelectric element is only a direction in which cold air and warm air are released when compared with the case in which the first storage chamber 110 is cooled by the first thermoelectric element 210. On the contrary, since the basic operation is the same, detailed description thereof will be omitted.

As mentioned above, although this invention was demonstrated in detail using the preferable Example, the scope of the present invention is not limited to a specific Example and should be interpreted by the attached Claim. In addition, those skilled in the art should understand that many modifications and variations are possible without departing from the scope of the present invention.

The cold and cold refrigerator for a vehicle according to the present invention can more efficiently transfer heat generated from a thermoelectric element into a storage compartment, and evenly distributes the items stored in the storage compartment regardless of the loading position because the temperature inside the storage compartment is evenly distributed. The advantage is that it can be cooled or cooled.
