Ordinarily, vehicles are transportation means that are provided with a prime mover powered by gasoline or light oil, and rotate wheels by using the power of the prime mover to run on a road. A vehicle is provided with a plurality of seats, and a refrigerator may be installed inside the vehicle.
Refrigerators store food items or medicines at low temperature, to keep them cold or prevent them from decaying. In recent years, a refrigerator is installed inside a vehicle, to meet the customer's needs.
A conventional vehicle refrigerator cools beverages or food items based on the Peltier effect. The Peltier effect means that in the case where two different sorts of metals are joined, and electric current passes through the metals, heat is generated and absorbed in proportion to the electric current at a joined portion between the metals.
In the case where electric current is applied reversely, heat is absorbed and generated reversely. In the case where a N-type semiconductor and a P-type semiconductor are arranged alternately and cooled or heated based on the Peltier effect, there may be a different of about 40° C. in temperature. With a thermoelectric semiconductor element, a vehicle refrigerator or a cooling and heating cabinet may be provided.
However, in the case where a beverage container and the like is stored in a conventional vehicle refrigerator, it is difficult to take out a plurality of beverage containers from the vehicle refrigerator and move them.
Additionally, in the case where a plurality of beverage containers are put into a tray and moved, since an additional cooling device is not provided in the tray, the temperature of the plurality of beverage containers refrigerated increases.
Further, in the case where a tray in which a beverage container is stored is mounted inside a vehicle refrigerator, cold air of the vehicle refrigerator is not delivered to the beverage container inside the tray.
As a related art, a refrigerator of a vehicle is disclosed in KR Patent No. 10-0845153 (registered on Jul. 3, 2008).

Accordingly, the beverage containers 200 are cooled by a cooling device provided at the vehicle refrigerator 100, such that the beverage containers 200 remain refrigerated in a vehicle.
To be readily put into and out of the vehicle refrigerator 100, the movable tray 1 moves up in an oblique direction. Since the movable tray 1 is attached to and detached from the vehicle refrigerator 100 by moving in an oblique direction, the exterior of the housing unit 10 of the movable tray 1 inclines to one side. Additionally, a mounting case 160 provided in the vehicle refrigerator 100 has a groove that inclines in the same direction as the moveable tray 1.
A cooling module unit 30 is installed inside the movable tray 1 that operates based on the Peltier effect. A cooling element 32 provided in the cooling module unit 30 is a thermoelectric module 142 operating based on the Peltier effect, and when necessary, performs a heating operation or a cooling operation.
The cooling module unit 30 is operated by a battery unit 40 built into the movable tray 1, and heat generated from the cooling module unit 30 is discharged out of the housing unit 10.

The outer housing 12 is installed in such a way that the outer housing 12 inclines to one side together with the refrigerated storage unit 20.
The vehicle refrigerator 100 is installed in a relatively small space at the lower side of a seat of a vehicle. Accordingly, in the case where the movable tray 1 stored in the vehicle refrigerator 100 is moved up perpendicularly, the movable tray 1 may be interfered with by the seat of the vehicle. To solve this problem, the movable tray 1 needs to be moved up at a slant in a forward direction.
Accordingly, the housing unit 10 which forms the exterior of the movable tray 1, and a mounting unit 150 of the vehicle refrigerator 100, in which the housing unit 10 is mounted, have a shape that inclines forward.
The outer housing 12 is provided with a rectangular bottom and shaped into a box the upper side of which is open, and has a front surface and a rear surface that inclines forward (the left side in
The outer housing 12 is provided with a first vent hole part 14 and a second vent hole part 16 that are a passage for air to move. The first vent hole part 14 is a passage in which air passing through the cooling module unit 30 moves. Since the first vent hole part 14 of one embodiment is installed respectively at both sides of the outer housing 12 in the widthwise direction W thereof, the first vent hole part 14 forms a passage in which air for cooling the cooling module unit 30 moves.
The first vent hole part 14 extends in the lengthwise direction D of the housing unit 10, along an edge that is a boundary between a lateral surface and the bottom surface of the housing unit 10, and forms a plurality of holes for air to move.
Since the pair of first vent hole parts 14 is installed at a position where the first vent hole parts 14 face each other, air, which is drawn into a first vent hole part 14 provided at one side of the housing unit 10 in the widthwise direction W thereof, is discharged out of the housing unit 10 through a first vent hole part 14 provided at the other side of the housing unit 10 in the widthwise direction W thereof.

An angle at which the housing unit 10 inclines with respect to a vertical line V and an angle at which the container storage unit 22 inclines with respect to the vertical line V may be the same. Since the housing unit 10 and the container storage unit 22 are installed in the state where the housing unit 10 and the container storage unit 22 incline, the movable tray 1 or the beverage container 200 may be taken out readily from the vehicle refrigerator 100 installed in a relatively small space.
The container storage unit 22 may be shaped into a circular pipe the lower side of which is closed, and formed in such a way that a material such as metal or aluminum having high heat conductivity is molded.
A central line C of the container storage unit 22 forms an acute angle with respect to the vertical line V and inclines. Under the assumption that an angle formed by the central line C of the container storage unit 22 and the vertical line V is referred to as a first angle A, the first angle A may be greater than 1 degree and less than 40 degrees.
Since the container storage unit 22 in which the beverage container 200 is mounted, and the housing unit 10 incline in one direction, the beverage container 200 or the movable tray 1 is drawn at a slant from the upper side of the movable body unit 120 in the state where the movable body unit 120 moves forward to the outside of a fixed body unit 110, such that the beverage container 200 or the movable tray 1 does not interfere with another component.

The first heat dissipating unit 36 is installed in the state of contacting the lower side of the cooling element 32, and since the first heat dissipating unit 36 exchanges heat with air, reduces the generation of heat of the cooling element 32. The first heat dissipating unit 36 of one embodiment comprises a heat dissipating plate 37, and a heat dissipating pin 38.
The heat dissipating plate 37, together with the container lower surface 23, is installed at a slant, in the state of contacting the lower side of the cooling element 32. The upper side of the cooling element 32 contacts the container lower surface 23, and the lower side of the cooling element 32 contacts the heat dissipating plate 37.
An angle formed between the heat dissipating plate 37 and a horizontal line is the same as the first angle A that is an angle formed between the central line C of the container storage unit 22 and the vertical line V. Additionally, since the bottom of the housing unit 10, disposed at the lower side of the heat dissipating plate 37, extends horizontally, the length of the heat dissipating pin 38 being perpendicular to the heat dissipating plate 37 and protruding to the lower side of the heat dissipating plate 37 increases gradually from one side of the heat dissipating plate 37 toward the other side of the heat dissipating plate 37.

The heat dissipating pin 38 of one embodiment is installed in a plurality of numbers in such a way that the plurality of heat dissipating pins 38 is installed in succession from one side of the heat dissipating plate 37 to the other side thereof. The heat dissipating pin 38 forms a plurality of rows along the lengthwise direction D of the heat dissipating plate 37. Additionally, the heat dissipating pin 38 is a rectangular plate that form waves, such that a surface area where the heat dissipating pin 38 exchanges heat with air increases.
Since the heat dissipating pin 38 extends in the widthwise direction W of the heat dissipating plate 37 and forms a plate that bends in a wave shape, such that the heat dissipating pin 38 has a greater surface area of contact with air than a planar plate.
Additionally, a length at which the heat dissipating pin 38 protrudes increases from one side of the heat dissipating plate 37 toward the other side thereof. As illustrated in
A flow of air through the first vent hole part 14 is based on a rotation of the cooling fan 34, and heat exchange between the first heat dissipating unit 36 and air is rapidly performed, such that the heat dissipation of the cooling element 32 is rapidly performed.
