Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings such that those skilled in the art may easily implement the present invention.

1 is a schematic explanatory diagram showing a state in which a cooler flows through a cold / hot refrigerator installed in an arm rest of an automobile according to the present invention.

As shown in FIG. 1, the cold / cold storage 100 according to the present invention may be installed in the front seat 11 or the rear seat 12. In the figure is shown an example in which the cold and warm storage 100 is installed on the rear seat 12.

In addition, a cooler discharge port 13 is formed in the lower portion of the front seat 11 so that the cooler can be delivered to the passenger of the rear seat 12. In addition, the rear seat 12 may be made of a seat cushion 14 and a seat back 15, the cold storage 100 according to the present invention may be coupled to the seat back 15 by a hinge 16.

In addition, as shown, the cooler flow passage 160 is formed in the lower portion or the side of the cold storage 100, so that the cool air from the cooler discharge port 13 can flow. Moreover, the cooler flow passage 160 is directly connected to the rear trunk 17. Therefore, the cold air of the air conditioner by the cooler flow passage 160 is rapidly discharged toward the trunk 17 while cooling the cold and hot storage 100.

Figure 2a is a cross-sectional view showing a cold and hot refrigerator installed on the arm rest of the vehicle according to an embodiment of the present invention, Figure 2b is a cross-sectional view showing a cold and hot refrigerator installed on the arm rest of the vehicle according to an embodiment of the present invention.

As shown, the cold and hot refrigerator 100 installed in the armrest of the vehicle according to the present invention is the armrest housing 110, Peltier element 120, blower fan 170, heat dissipation unit 140 and the cooler flow passage 160.

First, the armrest housing 110 may be installed at the center of the rear seat 12 or the front seat 11 of the vehicle as described above, but the installation position is not limited thereto. In addition, the armrest housing 110 includes a bottom surface 111 having a predetermined area and a sidewall 112 extending a predetermined height upward from a circumference of the bottom surface 111. In addition, any one side wall 112 of the side wall 112 is provided with an upper door 113 coupled by a hinge 114. Therefore, the upper door 113 can be opened at a predetermined angle upward from the armrest housing 110.

The Peltier element 120 may be installed in an approximately rear region of the armrest housing 110. As is well known, the Peltier element 120 absorbs heat when a predetermined power is applied in a climate such as summer. By dissipating heat, it can be used as a refrigerator, and under the same weather conditions as in winter, when the power is applied, the front side of the heat is released, and the rear side of the heat absorbed, it can be used as a warmer.

In the direct cooling (a in each drawing), heat transfer is performed by natural convection from the Peltier element 120 to the inside of the armrest housing 110 according to the temperature difference, but in the intercooling (b in each drawing) the circulation fan. 130 is coupled to the front of the Peltier element 120. By the circulation fan 130, circulation of the inside air (cold or hot air) of the armrest housing 110 occurs actively and thus the cooling performance is improved.

The heat dissipation unit 140 is approximately coupled to the rear of the Peltier element 120. That is, the heat dissipation unit 140 includes a heat sink 141 and a plurality of heat dissipation fins 142. The heat sink 141 made of a metal material having high thermal conductivity is directly coupled to the Peltier element 120. . In addition, a plurality of heat dissipation fins 142 are coupled to the rear of the heat sink 140 to increase the heat dissipation area. In addition, the heat dissipation fin 142 may be installed to extend to the inside of the cooler flow passage 160 to be described later. Of course, the heat dissipation fin 142 which is installed at the rear of the heat sink 141 and extends to the cooler flow passage 160 is thin and is stacked in a plurality of sheets at intervals, but the cooler flow passage 160 The portion extended into the heat dissipation performance of the rear and bottom surfaces of the Peltier element 120 by the heat dissipation unit 140 consisting of the heat sink 141 and the heat dissipation fins 142 should be in a state not to block the flow of air. This is improved. In addition, the portion extending into the cooler flow passage 160, which is the lower end of the heat dissipation fin 142, becomes a hollow conduit and has a high heat equivalent in the conduit to embed a latent heat transfer material having a high heat transfer rate, or a cooler flow passage. Material having a higher thermal conductivity than the heat dissipation fin 142 only in a portion extending into the heat sink 160 (it is generally economical to use only the portion in contact with the cooling / heating air rather than the entire heat dissipation fin as such a material because the material cost is high). It is apparent that such design changes are also within the protection scope of the present invention.

In addition, as shown, at least one of the front inlet, the middle region, or the rear outlet of the cooler flow passage 160 (only the head is shown in solid lines and the middle and tail are shown in dashed lines) is a cooler blower fan 170. If it is installed, it is possible to further improve the exchange rate of the cooler by improving the flow rate of air to improve the efficiency of the cold and hot storage.

Moreover, the cooler flow passage 160 includes a front inlet 161 through which the cooler is introduced and a rear outlet 162 through which the cooler is discharged toward the trunk. Accordingly, the cooler discharged from the lower portion of the front seat is introduced through the front inlet 161 of the cooler flow passage 160, and discharged toward the trunk through the rear outlet 162, so that the cooler 100 as a whole is Further improves cooling performance. In addition, by discharging the heat generated from the cold and warm storage (100) toward the trunk, so as not to cause discomfort to the driver or passenger in the cabin.

In addition, the cooler flow passage 160 formed at the lower portion (or outside of the side wall 112) of the bottom surface 111 of the armrest housing 110 has a rear outlet 162 at the heat dissipation portion 140. At the same time, at least one cooler blower fan 170 is further installed at a predetermined position of the cooler flow passage 160. Accordingly, the cooler introduced through the front inlet 161 of the cooler flow passage 160 is delivered more quickly to the rear outlet 162. Of course, the cold heater delivered as described above further increases the heat exchange of the heat dissipation fin 142 regardless of the presence or absence of the heat dissipation fan 150, thereby further improving the cooling performance of the cold / cold storage 100.

Here, the cooler blower fan 170 may be formed near the front inlet 161, the middle region (not shown) or the rear outlet 162 of the cooler flow passage 160. It does not limit the installation position in this invention.

As shown in the present invention, since the entire bottom surface 111 may be formed flat, the plurality of bottles or cans 200 may be laid down and stored. Therefore, it becomes possible to improve the volume inside the cold compartment 100, it is possible to refrigerate or warm more number of bottles or cans 200.

Figure 3a is a cross-sectional view showing a cold and hot refrigerator installed on the arm rest of the vehicle according to another embodiment of the present invention, Figure 3b is a cross-sectional view showing a cold and hot refrigerator installed on the arm rest of the vehicle according to another embodiment of the present invention to be.

As shown, the cold and hot refrigerator 100 according to another embodiment of the present invention has a configuration substantially the same as the above-described cold and cold storage 100, and will be described herein based on the differences and the same parts as the above-described configuration. Are given the same number and the description is omitted.

As shown, the heat radiating fan 150 is formed near the rear outlet 162 of the air conditioner cold air flow passage 160. That is, in the cold / hot refrigerator 100, there is no heat dissipation fan 150, but in the cold / hot refrigerator 100, the heat dissipation fan 150 is the rear of the heat sink 141 and the heat dissipation fin 142, and the air conditioner cold air flow passage. The one formed near the rear exit 162 of 160 is different. Of course, in this case, it is critical that the air conditioner cold air flow path 160 is also bent upward from the rear portion so as to be smoothly circulated. Thus, the cold / hot refrigerator 100 according to the present invention positions the heat dissipation fan 150 toward the rear side. By doing so, the entire bottom surface 111 can be formed flat, thereby maximizing the internal volume of the cold / cold storage 100.

In addition, heat exchange into the housing 110 may be used in both direct cooling and intercooling, as described above.

Figure 4a is a cross-sectional view showing a cold and hot refrigerator installed on the armrest of the vehicle according to another embodiment of the present invention, Figure 4b is a cross-sectional view showing a cold and hot refrigerator installed on the armrest of the vehicle according to another embodiment of the present invention to be.

The cold / hot refrigerator 100 according to another embodiment of the present invention also has a configuration substantially the same as the above-mentioned cold / hot refrigerator 100. Here, the differences will be described based on the differences, and the same reference numerals are used for the same components.

As shown, the Peltier element 120 may be formed on an approximately bottom surface 111 of the armrest housing 110. Of course, the heat sink 141 for cooling the Peltier element 120 is also formed under the bottom surface 111. In addition, a plurality of heat dissipation fins 142 extend to the lower portion of the heat sink 141 which is the lower portion of the bottom surface 111. Here, the blower fan 170 is formed on the upper portion of the Peltier element 120, so that the Peltier element 120 may slightly protrude upward.

In addition, the cooler flow passage 160 formed at the lower portion (or outside of the sidewall 112) of the bottom surface 111 of the armrest housing 110 has a rear outlet 162 having a heat dissipation unit 140 and a heat dissipation fan ( At the same time, a plurality of cooler blowing fans 170 are installed at predetermined positions of the cooler flow passage 160. In addition, as described above, the heat dissipation fin 142 of the heat dissipation unit 140 extends a predetermined length to the bottom surface 111 of the armrest housing 110. Therefore, the length of the heat dissipation fin 142 as a whole is shortened, which improves the heat transfer rate, so that the cooling performance of the cold / cold storage 100 is the best. In addition, the rear outlet 162 of the cooler flow passage 160 is connected to the trunk, so that the heat generated from the heat dissipation fin 142 and the extension 143 as described above is also discharged to the trunk instead of flowing into the cabin. Drivers and passengers in the cabin will not be offended.

In addition, in another embodiment of the present invention, the Peltier element 120 is installed on the bottom surface 111 of the armrest housing 110. Of course, the drawings are shown as if installed in the center of the lower surface in order to obtain a visual effect, it may be located in the front or rear of one corner rather than the center, it is obvious that the present invention is not limited to the exemplary drawings.

In addition, as the Peltier element 120 is installed on the bottom surface 111, the heat sink 141 and the heat dissipation fin 142 are also located together, and the circulation fan 130 may be installed on the inner surface side of the housing 110. have. Due to this arrangement, compared to other embodiments of the present invention shown in FIGS. 2 and 3, the inside of the housing 110 is further extended in the longitudinal direction, so that a large plastic bottle can also be used. In addition, since the heat exchange element is located on the bottom surface 111, the convection is more smoothly and the heat exchange rate can be increased.

Figure 5 and Figure 6 is a state of use of cold and cold storage installed in the armrest of the vehicle according to the embodiment of the present invention.

As shown, according to the aqueous solution of the present invention, the cooler flow passage 160 may be formed in the entire lower portion of the bottom surface 111 or a partial region of the lower portion of the armrest housing 110. Although the cooler flow passage 160 is shown as being formed in a portion of the bottom surface 111 in FIG. 5, as shown in FIG. 6, the cooler flow passage 160 has a lower portion of the bottom surface 111. It should be noted that they may be formed throughout. In addition, as a matter of course, the cooler flow passage 160 should be formed to pass through the heat dissipation fin 142 and the heat dissipation fan 150. That is, the heat dissipation performance of the cold / cold storage 100 is improved only when the cold air sucked through the cool air flow channel 160 passes through the heat dissipation fins 142.

On the other hand, when the cooler flow passage 160 is formed in the entire lower portion of the bottom surface 111 or only a part of the width of the armrest housing 110 in the longitudinal direction, the heat dissipation portion inside the cooler flow passage 160 The heat dissipation fin 142 and the blowing fan 170 may be installed. Therefore, a large amount of cooler introduced through the front inlet 161 of the cooler flow passage 160 is widely transmitted to the heat dissipation fin 142 and then discharged to the outside through the rear outlet 162. In this way, the cooler increases the cooling efficiency of the heat radiating fin 142. In addition, due to the heat dissipation fan 150 installed in the heat dissipation fin 142, the heat dissipation wind and the cooler are quickly discharged toward the trunk.

Reference numeral 200 in the drawings shows a variety of bottles and cans and the like stored in the cold and cold storage 100 according to the present invention. As shown in the figure, the heat sink fin 142 and the heat dissipation fan 150 is formed at a position where a small can or the like is suitable, and the heat dissipation fin and the heat dissipation fan is not formed on the bottom surface 111 is relatively large bottle It is suitable when the back is located. In this case, the heat dissipation fin and the heat dissipation fan may be formed in a predetermined area of the bottom surface 111 that is slightly protruded upward by the cooler flow passage 160. Therefore, the overall specification of the housing 110 may be adjusted. When the same, the internal volume is reduced to make it impossible to accommodate the large interior 200, as shown in Figure 6 to form the air conditioner cold air flow path 160 only on a portion of the bottom surface 111 In this case, the air conditioner cold air flow path 160 is not formed in the bottom surface 111 is formed lower than the surroundings to increase the storage height is also possible to accommodate a high-standard interior 200, this structure is obtained only in the present invention It is a unique structure.

On the other hand, in the cold and cold storage 100 of the present invention described above and described as the cooler flow flow path 160 is formed on the bottom surface 111 of the armrest housing 110, as seen from the description and drawings It is not intended to limit the invention. That is, the cooler flow passage 160 may be formed on the side wall 112 or the upper door 113 of the armrest housing 110.

As described above, in the cold storage device installed in the armrest of the vehicle according to the present invention, various types of cooler flow passages are formed in the lower part, whereby the heat dissipation performance of the heat dissipation part is further improved, and thus the cooling performance of the cold storage device is also improved. It works.

In addition, the cold and hot refrigerator installed in the armrest of the vehicle according to the present invention is further provided with a cooler blower fan in a predetermined region of the cooler flow flow path, thereby increasing the flow rate of the cooler, and thus the heat dissipation performance of the radiator and cooling of the cold storage The performance is further improved.

In addition, the hot and cold storage installed in the armrest of the vehicle according to the present invention is connected to the cooler flow flow path toward the trunk, so that the heat generated from the cold and cool storage is discharged to the trunk rather than transferred into the cabin. Therefore, there is also an effect that the discomfort caused by the heat generated from the cold and hot storage is not caused to the driver or passenger in the vehicle compartment.
