Description

Technical Field

[0001] The present invention relates to a cooling device with increased cooling efficiency. More specifically, a cooling rod is installed penetrating the inside of a storage chamber, and the cooling rod is configured to cool an object to be cooled stored inside the storage chamber. By filling the cooling rod or the storage chamber with a cooling auxiliary solution for increasing the cooling efficiency, even in an environment with a high external temperature, the internal temperature of the storage chamber can be cooled to a preset temperature, and the present invention relates to a cooling device with increased cooling efficiency.

Background Art

[0002] Generally, as a cooling means for small household appliances such as small refrigerators, small water purifiers, and cold water mats, thermoelectric elements are mainly used.

[0003] At this time, a thermoelectric element is a semiconductor element in which heat dissipation (heating) occurs at the forward junction and heat absorption (cooling) occurs at the reverse junction when an electric current is applied, and it can be realized with low power and ultra-small size.

[0004] Republic of Korea Registered Utility Model No. 20-0390039 (invention name: Cooling device for a grain refrigerator) (hereinafter referred to as "the prior art") is a grain refrigerator to which such a thermoelectric element is applied.

[0005] FIG. 1 is a perspective view of the prior art. As shown in FIG. 1, the prior art 900 includes a cooling post 910, a housing 920, a heater wire 930, a heat radiation fin 940, and a cooling fan 950.

[0006] The cooling post 910 is formed in a cylindrical shape and is made of a material with excellent thermal conductivity.

[0007] Further, a Peltier element 911 is attached to the lower surface of the cooling post 910.

[0008] When an electric current flows through the Peltier element 911, one surface is cooled and the other surface is heated.

[0009] In this type of Peltier element 911, the surface to be cooled is attached to the cooling post 910, transferring cold air to the cooling post 910, and the surface to be heated is attached to the heat dissipation fin 940, releasing hot air to the outside.

[0010] The housing 920 is installed to enclose the cooling post 910 and transfer the cool air emitted from the cooling post 910 to the grain.

[0011] Furthermore, the housing 920 is made of a breathable and moisture-absorbing material such as loess or charcoal, which can absorb moisture that may be generated during the cooling process and prevent the grain from being exposed to moisture.

[0012] The heater wire 930 is installed in the space between the cooling post 910 and the housing 920. A humidity sensor (not shown) installed inside the housing 920 determines that moisture has formed on the outer surface of the cooling post 910 due to condensation when the internal humidity of the housing 920 exceeds a critical value, and removes the moisture formed on the outer surface of the cooling post 910 using heat.

[0013] The heat dissipation fin 940 is in contact with the Peltier element 911 on one side, and releases the heat transferred through the Peltier element 911 to the outside.

[0014] The cooling fan 950 is installed on the heat dissipation fin 940 and expels the heat from the heat dissipation fin 940 to the outside.

[0015] In a grain refrigerator to which the conventional technology 900 configured in this manner is applied, the grain inside is cooled by the cooling post 910 and the housing 920, and the moisture inside the housing 920 is removed by the heater wire 930, thereby preventing the moisture inside the housing 920 from leaking out and causing the grain to rot or be damaged.

[0016] However, such conventional technology 900 lacks any additional means to increase the cooling efficiency of the cooling post 910. Therefore, when the cooling of the cooling post 910 is carried out by a single Peltier element 911, not only does the time required to cool the cooling post 910 to the target set temperature increase, but if the external temperature is high, a problem arises in which it becomes impossible to cool it to the target temperature. [Overview of the Initiative] [Problems that the invention aims to solve]

[0017] The present invention aims to solve these problems, and the object to be cooled by the present invention is to provide a cooling device with increased cooling efficiency in which a cooling rod is installed penetrating the inside of a storage chamber in which an object to be cooled is stored, and the cooling rod installed inside the storage chamber is cooled by a thermoelectric element, thereby cooling the object to be cooled inside the storage chamber.

[0018] Another problem to be solved by the present invention is to provide a cooling device with increased cooling efficiency, which not only increases the cooling rate by attaching an allotrope of carbon with high thermal conductivity to the cooling rod, but also allows the temperature of the cooling rod to be smoothly cooled to the target temperature even when the external temperature is high.

[0019] Another problem to be solved by the present invention is to provide a cooling device with increased cooling efficiency in which a ring-shaped ice generating section is installed to enclose the outer surface of the cooling rod, but is installed in a position adjacent to the thermoelectric element, so that the cold air from the thermoelectric element fills the inside with ice, and the inside of the cooling rod and storage chamber can be cooled rapidly by the ice that has filled the inside.

[0020] Furthermore, another problem to be solved by the present invention is to provide a cooling device with increased cooling efficiency, in which the cooling rate of the cooling rod is increased by filling the inside of the cooling rod with a cooling auxiliary solution having high thermal conductivity and heat capacity, and by preventing the inflow of heat from the outside by installing insulating material that wraps around the side walls and bottom of the storage chamber, thereby reducing the internal temperature of the storage chamber to the temperature set by the user, even in environments with high external temperatures.

[0021] Furthermore, another problem to be solved by the present invention is to provide a cooling device with increased cooling efficiency, which can increase the cooling efficiency of thermoelectric elements by installing a second heat sink in the shape of a rectangular plate on top of a heat sink fin structure, and a first heat sink formed in the shape of a cross and installed on top of the second heat sink, with each end positioned outside the second heat sink, and by making the first and second heat sinks out of a material such as copper or silver which has a higher thermal conductivity than aluminum which is used in existing heat sink structures, thereby increasing the heat dissipation efficiency.

[0022] Furthermore, another problem to be solved by the present invention is to provide a cooling device with increased cooling efficiency, in which an allotrope of carbon having high thermal conductivity is inserted between the heat dissipation fin structure and the second heat dissipation plate, and between the second heat dissipation plate and the first heat dissipation plate, thereby increasing the overall thermal conductivity of the heat dissipation section and increasing the heat dissipation efficiency.

[0023] Another problem to be solved by the present invention is to provide a cooling device with increased cooling efficiency, in which, when a cooling rod having a structure in which a plurality of ice buckets with internal spaces are connected is cooled by a thermoelectric element, ice is sequentially generated from the ice buckets installed adjacent to the thermoelectric element, and the water inside the storage chamber is cooled by the ice generated inside the ice buckets. This not only cools the water to a constant temperature with ice, but the contact area with the water is increased by the cooling rod installed inside the chilled water tank, and the water contained inside the chilled water tank is cooled uniformly.

[0024] Another problem to be solved by the present invention is that since a cooling tube filled with a cooling auxiliary solution having a large heat capacity is installed inside the cold water tank, even if the cooling of the thermoelectric element is interrupted due to a power failure or a malfunction, the ice generated inside the cooling rod and the cooling auxiliary solution filled inside the cooling tube can maintain cold air for a long time, and the temperature of the water stored inside the cold water tank can be maintained cold for a long time, providing a cooling device with increased cooling efficiency.

[0025] Another problem to be solved by the present invention is that a cold air transmission part with a thermoelectric element attached to the rear end for directly transmitting cold air is installed to wrap the cooling rod, so that the cold air of the thermoelectric element can be uniformly transmitted to the whole cooling rod, increasing the speed at which ice is generated inside the ice bucket, and providing a cooling device with increased cooling efficiency.

[0026] Another problem to be solved by the present invention is that a cooling tube filled with a cooling auxiliary solution is arranged inside the ice bucket, and the cooling tube is connected to the cold air transmission part and configured to transmit cold air, so that even if the cooling of the thermoelectric element is interrupted due to a malfunction or a power failure, the time taken for the ice generated inside the ice bucket to melt can be increased, and cooling can be carried out for a long time, providing a cooling device with increased cooling efficiency.

[0031] In addition, the present invention relates to a cooling device installed in a storage chamber for cooling an object to be cooled stored inside the storage chamber. The cooling device includes a cooling rod that penetrates the bottom surface of the storage chamber and is installed inside the storage chamber, with the lower end portion located below the bottom surface of the storage chamber, a cooling means installed on the lower surface of the cooling rod, and a heat radiating portion installed on the lower surface of the cooling means for discharging the heat generated from the cooling means to the outside. On the outer peripheral surface of the cooling rod, an adhesive material having an allotrope of carbon attached to the adhesion surface is attached at intervals in the vertical direction of the cooling rod.

[0032] In addition, in the present invention, the allotrope of carbon is graphite in which layers are separated by a peeling process.

[0033] In addition, in the present invention, it is preferable that a cooling auxiliary solution insertion groove into which a cooling auxiliary solution and cotton are inserted is formed on the upper surface of the cooling rod.

[0034] Furthermore, the present invention relates to a cooling device comprising a mat section in which a circulation pipe through which water is circulated is installed, and a chilled water circulation section connected to the circulation pipe and for cooling the circulating water, wherein the chilled water circulation section comprises a case, a chilled water tank installed inside the case and containing water, and connected to the circulation pipe, a cooling section for cooling the water contained inside the chilled water tank, and a motor for circulating the water contained inside the chilled water tank, wherein the cooling section comprises a cooling rod formed in the shape of a rod and installed inside the chilled water tank, and a cooling means for cooling the cooling rod, wherein the cooling rod is formed in the shape of a column with a space inside and includes a plurality of ice buckets in which ice is generated inside when cooled.

[0035] Furthermore, in the present invention, it is preferable that the chilled water circulation section further includes at least one cooling tube which is formed in the shape of a rod, installed inside the chilled water tank, has its outer surface in contact with the cooling rod, and is filled with a cooling auxiliary solution.

[0036] Furthermore, in the present invention, the cooling auxiliary solution is preferably prepared by mixing 70-80% by weight of acetic acid and 20-30% by weight of salt.

[0037] Furthermore, the present invention relates to a cooling device installed in a storage chamber for cooling an object to be cooled stored inside the storage chamber, and includes: a cooling rod installed inside the storage chamber, penetrating the bottom surface of the storage chamber, but with its lower end located below the bottom surface of the storage chamber; a cooling means installed on the lower surface of the cooling rod; a heat dissipation unit installed on the lower surface of the cooling means, which releases heat generated from the cooling means to the outside; and a cooling auxiliary ring formed in the shape of a ring with a space formed inside, through which the cooling rod penetrates, and installed at a position adjacent to the lower end of the cooling rod when installed.

[0038] Furthermore, in the present invention, the cooling means is preferably a thermoelectric element. [Effects of the Invention]

[0039] According to the present invention, which has the above-mentioned problems and solutions, a cooling rod is installed penetrating the inside of a storage chamber in which an object to be cooled is stored, and the cooling rod installed inside the storage chamber is cooled by a thermoelectric element, thereby enabling the object to be cooled stored inside the storage chamber to be cooled.

[0040] Furthermore, according to the present invention, by attaching an allotrope of carbon with high thermal conductivity to the cooling rod, the cooling efficiency of the cooling rod is increased, which not only increases the cooling rate but also allows the temperature of the cooling rod to be smoothly cooled to the target temperature even when the external temperature is high.

[0041] Furthermore, according to the present invention, the ring-shaped ice generating section is installed to enclose the outer surface of the cooling rod, and by being installed in a position adjacent to the thermoelectric element, the cold air from the thermoelectric element fills the inside with ice, and the ice that fills the inside can rapidly cool the inside of the cooling rod and the storage chamber.

[0042] Furthermore, according to the present invention, the cooling rod is filled with a cooling aid solution that has high thermal conductivity and heat capacity, which not only increases the cooling rate of the cooling rod, but also prevents heat from entering from the outside by insulating material that is installed to enclose the side walls and bottom of the storage chamber. As a result, even in environments with high external temperatures, the internal temperature of the storage chamber can be reduced to the temperature set by the user.

[0043] Furthermore, according to the present invention, a second heat sink in the shape of a rectangular plate is installed on the upper part of the heat sink fin structure, and a first heat sink is formed in a cross shape and installed on the upper part of the second heat sink, with each end positioned outside the second heat sink. The first and second heat sinks are made of materials such as copper or silver, which have a higher thermal conductivity than aluminum, which is used in existing heat sink structures, thereby increasing the heat dissipation efficiency and increasing the cooling efficiency of the thermoelectric element.

[0044] Furthermore, according to the present invention, allotropes of carbon having high thermal conductivity are inserted between the heat dissipation fin structure and the second heat sink, and between the second heat sink and the first heat sink, thereby increasing the thermal conductivity of the entire heat dissipation section and increasing the heat dissipation efficiency.

[0045] Furthermore, according to the present invention, when a cooling rod having a structure in which a plurality of ice buckets with internal spaces are connected is cooled by a thermoelectric element, ice is sequentially generated from the ice buckets installed adjacent to the thermoelectric element, and the water inside the storage chamber is cooled by the ice generated inside the ice buckets. As a result, the water is not only cooled to a constant temperature by the ice, but the contact area with the water is increased by the cooling rod installed inside the chilled water tank, and the water contained inside the chilled water tank is cooled uniformly.

[0046] Furthermore, according to the present invention, since a cooling tube filled with a cooling auxiliary solution with a large heat capacity is installed inside the chilled water tank, even if the cooling of the thermoelectric element is interrupted due to a power outage or malfunction, the ice generated inside the cooling rod and the cooling auxiliary solution filled inside the cooling tube will maintain the cold air for a long period of time, and the temperature of the water contained inside the chilled water tank will remain cold for a long period of time.

[0047] Furthermore, according to the present invention, by installing a cold air transfer section, to which a thermoelectric element is attached at the rear end and to which cold air is directly transferred, so as to enclose the cooling rod, the cold air from the thermoelectric element can be uniformly transferred to the entire cooling rod, thereby increasing the rate at which ice is formed inside the ice bucket.

[0048] Furthermore, according to the present invention, a cooling tube filled with a cooling auxiliary solution is placed inside the ice bucket, and the cooling tube is connected to a cold air transfer unit so that cold air is transferred. This increases the time it takes for the ice generated inside the ice bucket to melt, even if the cooling of the thermoelectric element is interrupted due to a malfunction or power outage, allowing for cooling for a longer period of time.

[0050] An embodiment of the present invention will be described below with reference to the attached drawings.

[0051] Figure 2 is a cross-sectional view of a first cooling device, which is a first embodiment of the present invention.

[0052] The first cooling device 100 is a device that can uniformly cool the water stored inside the storage chamber by installing cooling rods in the vertical direction inside the storage chamber and cooling the water inside the storage chamber with the cooling rods.

[0053] As shown in Figure 2, the first cooling device 100 consists of a case 120, a storage chamber 130, a cooling section 140, and a drainage section 150.

[0054] The case 120 is formed in the shape of a box with an open top, and a storage chamber 130, a cooling section 140, and a drainage section 150 are installed inside.

[0055] In Figure 2, for the sake of explanation, the case 120 is shown as being in the shape of a rectangular box. However, the shape of the case 120 is not limited to this, and it may be formed in various shapes such as a cylinder or a polygonal prism.

[0056] Furthermore, a water pipe insertion hole 121 is formed on one side of the case 120, through which the water pipe 151, described later, passes.

[0057] Figure 3 is a cross-sectional perspective view of the storage room shown in Figure 2.

[0058] As shown in Figure 3, the storage chamber 130 is formed in the shape of a box with an open top.

[0059] Furthermore, a cooling aid solution 131 and cotton are inserted into the side walls and bottom surface of the storage chamber 130.

[0060] The cooling aid solution 131 is a solution consisting of 70-80% by weight of acetic acid and 20-30% by weight of salt, and is inserted into the side walls and bottom surface of the storage chamber 130 in a state absorbed by cotton.

[0061] Since the cooling aid solution 131 has high thermal conductivity and heat capacity when a salt is dissolved in acetic acid, the thermal conductivity and heat capacity of the storage chamber 130 into which the cooling aid solution is inserted are increased, thereby increasing the cooling efficiency.

[0062] Furthermore, since the cooling aid solution 131 is absorbed by the cotton and then inserted into the storage chamber 130, the storage period is longer than if it were inserted in liquid form.

[0063] Such a cooling auxiliary solution 131 not only has high thermal conductivity but also a large heat capacity, so even if the external temperature drops, it maintains a cooling state for a long time, and even when the cooling of the Peltier element 1411 is interrupted due to a power outage, malfunction, etc., it maintains the cooling state of the storage chamber 130, thereby increasing the time it takes for the temperature of the water stored inside the storage chamber 130 to rise.

[0064] In addition, insulation material 132 is installed on the outside of the side walls and bottom surface of the storage room 130.

[0065] The insulation material 132 not only prevents external heat from flowing into the storage chamber 130, but also prevents internal cold air from being released to the outside, thereby preventing a decrease in cooling efficiency.

[0066] In addition, multiple partition walls 133 are installed inside the storage room 130.

[0067] The partition wall 133 is formed in the shape of a plate and is installed inside the storage chamber 130, separated vertically, to divide the internal space of the storage chamber 130. However, it is configured so that water can move through it by forming a drain hole 1331.

[0068] Such a storage chamber 130 is configured such that the water stored inside is divided by a partition wall 133 and flows through a drain hole 1331, and the convection velocity is reduced. As a result, when room temperature water is supplied from the outside, the water adjacent to the drain section 150 mixes with the water supplied from the outside, preventing the temperature from rising.

[0069] In other words, even when water is supplied from the outside, the storage chamber 130 has a reduced convection velocity due to the partition wall 133, which not only prevents the water stored inside from mixing with the water supplied from the outside and causing a rapid rise in temperature, but also ensures that the water supplied from the outside has sufficient time to be cooled by the cooling unit 140, thereby preventing the temperature of the water discharged from the drainage unit 150 from rising.

[0070] Furthermore, a cooling rod through-hole 134 and a drainage connection hole 135 are formed on the lower surface of the storage chamber 130, through which the cooling rod 141 (described later) passes.

[0071] In the storage chamber 130 configured in this way, the cooling aid solution 131 is filled inside the side walls and bottom surface, increasing the cooling efficiency. This not only allows the water stored inside the storage chamber 130 to cool quickly, but also prevents external heat from flowing into the interior. As a result, the water stored inside can be cooled quickly, and the internal temperature of the storage chamber 130 can be maintained even when the external temperature is high.

[0072] Furthermore, the storage chamber 130, by reducing the convection velocity of the water through the partition wall 133, can prevent the temperature of the water discharged from the drainage section 150 from rising even when room temperature water is supplied from the outside.

[0073] Figure 4 is an exploded perspective view of the cooling unit in Figure 2, and Figure 5 is a cross-sectional view of the cooling unit in Figure 2.

[0074] As shown in Figure 4, the cooling section 140 consists of a cooling rod 141, a heat sink structure 142, a cooling fan 143, and a pipe 144.

[0075] The cooling rod 141 is formed in the shape of a circular rod, and a Peltier element 1411 is attached to its lower surface.

[0076] The Peltier element 1411 is an element that operates on the principle that when an electric current flows through it, one side is cooled and the other side is heated.

[0077] In this type of Peltier element 1411, one side is attached to the lower surface of the cooling rod 141 to cool the cooling rod 141, and the other side is attached to the upper surface of the heat sink structure 142 to heat the heat sink structure 142.

[0078] Furthermore, the inside of the cooling rod 141 is filled with salt S.

[0079] Since salt S has low thermal conductivity, it is not only rapidly cooled by the cold air generated from the Peltier element 1411, but it also becomes contaminated with the cold air generated from the Peltier element 1411.

[0080] By filling the inside of such a cooling rod 141 with salt S, the cooling efficiency is increased, and even when the external temperature (i.e., outside the case) is high, the internal temperature of the storage chamber 130 can be cooled to a predetermined temperature.

[0081] The heat sink structure 142 consists of a flat heat sink frame 1421 on which a Peltier element 1411 is attached to the upper surface, and a plurality of flat heat sinks 1422 that are perpendicularly connected to the lower surface of the heat sink frame 1421.

[0082] This heat sink structure 142 receives the hot air generated from the Peltier element 1411 via the heat sink frame 1421 and releases the hot air into the atmosphere via the heat sink 1422.

[0083] The cooling fan 143 is installed below the heat sink structure 142 and cools the heat sink structure 142, thereby expelling the hot air from the Peltier element 1411 to the outside more quickly, and ensuring that the cooling process of the cooling rod 141 proceeds smoothly.

[0084] The pipe body 144 is formed in a circular tubular shape with a closed upper end, and consists of a double wall body with an inner wall 1441 and an outer wall 1442.

[0085] Furthermore, the first dividing plate 1443 and the second dividing plate 1444 are installed inside the pipe body 144, spaced apart from each other in the vertical direction.

[0086] Furthermore, the pipe body 144 is configured such that water can flow in and out through multiple through holes 1445 formed in the inner wall 1441, the outer wall 1442, and the dividing plates 1443 and 1444.

[0087] At this time, the inner wall 1441 of the pipe body 144 is made of a material with high thermal conductivity and is rapidly cooled by the cold air released from the cooling rod 141, causing its temperature to drop, while the outer wall 1442 is made of a material with low thermal conductivity and has a relatively higher temperature than the inner wall 1441.

[0088] Such a pipe 144 is configured such that its internal space is separated by a first dividing plate 1443 and a second dividing plate 1444, but through holes 1445 allow water to move between each space.

[0089] For the sake of explanation, the space formed between the storage chamber 130 and the first dividing plate 1443 will be described as area A, the space formed between the first dividing plate 1443 and the second dividing plate 1444 will be described as area B, and the space formed between the second dividing plate 1444 and the upper surface of the pipe body 144 will be described as area C.

[0090] Since region A is formed in the position closest to the Peltier element 1411, the temperature inside the storage chamber 130 will decrease the fastest.

[0091] As a result, ice forms in area A based on the cooling rod 141, inner wall 1441, and first dividing plate 1443 located inside area A, and as time passes, the entire area A is filled with ice.

[0092] Since region B is located further from the Peltier element 1411 than region A, ice formation in region B begins even later than in region A. However, because it is adjacent to region A, ice forms inside due to the cold air transmitted from region A and the cooling rod 141, and as time passes, the entire region B is filled with ice.

[0093] Since region C is located further from the Peltier element 1411 than regions A and B, ice formation begins even later in region C than in regions A and B. However, ice forms inside region C due to the cold air transmitted from region C and the cooling rod 141, and as time passes, the entire region C is filled with ice.

[0094] In other words, during cooling, ice is sequentially formed and filled in regions A, B, and C of the pipe 144, forming a long structure in the vertical direction, and preventing ice from forming on the outer wall 1442, thereby guiding the internal space to be filled with ice.

[0095] At this time, the water stored inside the storage chamber 130 is cooled by the cold air from the ice formed inside the pipe 144, which not only increases the cooling rate but also ensures that the water is cooled uniformly in the vertical direction.

[0096] Furthermore, the water stored inside the storage chamber 130 is configured to come into direct contact with the ice through through-holes 1445 formed in the pipe 144, thereby directly transferring the cold air from the ice and increasing the cooling rate.

[0097] In such a tube 144, ice is filled into the internal space (regions A, B, and C), and the ice forms a long shape in the vertical direction. This cools not only the water located at the bottom of the storage chamber 130 adjacent to the Peltier element 1411, but also the water located at the top. This increases the contact area with the water stored inside the storage chamber 130, allowing the water stored inside the storage chamber 130 to be cooled uniformly.

[0098] Furthermore, the pipe body 144 can prevent the drainage section 150 from being blocked by ice by fixing the shape and position of the ice formed on the outer surface of the cooling rod 141.

[0099] The drainage section 150 consists of a water pipe 151 and a cock 152.

[0100] The water distribution pipe 151 is connected at one end to the storage chamber 130, and the other end is installed protruding from the outside of the case 120.

[0101] Furthermore, a cock 152 is installed at the other end of the water distribution pipe 151, so that the user can drain the water inside the storage room 130 by operating the cock 152.

[0102] At this time, a check valve 1511 is installed inside the water distribution pipe 151.

[0103] The check valve 1511 is installed at the connection point between the storage chamber 130 and the water pipe 151 and is configured to open only when the cock 152 is operated by the user, thereby preventing backflow of water or air discharged to the outside.

[0104] Such a check valve 1511 can prevent the temperature of the water stored inside the storage chamber 130 from rising due to air or water flowing back from the water pipe 151.

[0105] In the first cooling device 100 configured in this way, ice is formed in a long vertical direction by the pipe 144 that encloses the cooling rod 141. However, the shape of the ice is restricted by the pipe 144, so that the water inside the storage chamber 130 is cooled uniformly by the ice that is formed in a long vertical direction, and the cooling rate is increased.

[0106] Furthermore, the first cooling device 100 is configured such that when water is supplied from the outside, the temperature of the water stored inside does not drop rapidly due to the supply of water, as multiple partition walls 133 are installed inside the storage chamber 130 to reduce the convection velocity of the water. In addition, the cooling auxiliary solution 131 and insulation material 132 filled inside the side walls and bottom surface of the storage chamber 130 are configured to keep the cold air released from the cooling unit 140 inside the storage chamber 130, thereby increasing the cooling efficiency.

[0107] Such a first cooling device 100 is configured to cool the water stored inside the storage chamber 130 to the user's desired temperature, even in environments with high external temperatures, without the need to install multiple Peltier elements 1411, thereby reducing manufacturing costs and maintenance costs.

[0108] Figure 6 is a perspective view of a second cooling device, which is a second embodiment of the present invention; Figure 7 is a cross-sectional example of Figure 6; and Figure 8 is a cross-sectional example of the cooling device and a storage room in which the cooling device is installed.

[0109] The second cooling device 200 is installed in small refrigerators such as cosmetic refrigerators and wine refrigerators, and is configured to cool the inside of the refrigerator using a cooling rod. By attaching an allotrope of carbon with high thermal conductivity to the surface of the cooling rod, the cooling efficiency of the cooling rod can be increased.

[0110] As shown in Figures 6 and 7, the second cooling device 200 consists of a cooling rod 210, a heat dissipation unit 220, and a cooling fan 230.

[0111] As shown in Figure 8, in this second cooling device 200, a cooling rod 210 is installed inside a storage chamber 240 in which an object to be cooled (not shown) is stored, thereby cooling the object to be cooled.

[0112] At this time, a cooling rod through-hole 241 is formed in the bottom surface of the storage chamber 240 through which the cooling rod 210 passes.

[0113] The cooling rod 210 is formed in the shape of a circular rod, and a Peltier element 211 is attached to its lower surface.

[0114] The Peltier element 211 is an element that operates on the principle that when an electric current flows, one side is cooled and the other side is heated.

[0115] In this type of Peltier element 211, the upper surface that is cooled is attached to the lower surface of the cooling rod 210, cooling the cooling rod 210, and the lower surface is attached to the upper surface of the heat dissipation section 220, heating the heat dissipation section 220.

[0116] Furthermore, adhesive material 212, on which an allotrope of carbon D is attached to the adhesive surface, is attached to the outer surface of the cooling rod 210 at intervals in the vertical direction.

[0117] The adhesive material 212 is formed in the shape of a strip with an adhesive surface on one side, and is attached in a ring shape to the outer surface of the cooling rod 210, with multiple pieces attached at intervals in the vertical direction.

[0118] In this case, it is preferable that the adhesive material 212 be a thermal conductive tape with a higher thermal conductivity than ordinary tape.

[0119] Furthermore, when the adhesive material 212 is attached, allotrope D of carbon is attached to the adhesive surface, and the adhesive material 212 is attached to the outer surface of the cooling rod 210, so that allotrope D of carbon and the outer surface of the cooling rod 210 are in close contact.

[0120] Furthermore, the adhesive material 212 has multiple through holes 2121 spaced apart in the longitudinal direction, so that when the release of cold air from the cooling rod 210 is blocked by the adhesive material 212, cold air is released from the through holes 2121, thereby preventing a temperature difference from occurring between the parts to which the adhesive material 212 is attached and the parts to which it is not attached.

[0121] In this case, the allotrope D of carbon consists of graphite powder with separated layers.

[0122] Graphite is an allotrope of carbon with excellent thermal and electrical conductivity, and it consists of multiple layers.

[0123] Such graphite exhibits anisotropy, where the thermal conductivity in the planar direction of each layer is higher than the thermal conductivity in the layer direction.

[0124] In other words, graphite has relatively low thermal conductivity in the layer direction, and as the number of layers increases, the thermal conductivity decreases. Therefore, reducing the number of layers can increase the thermal conductivity.

[0125] One method used to separate the graphite layer is a physical delamination method that involves using tape to peel off the graphite layer.

[0126] The physical method of removing graphite used in this case involves attaching powdered graphite to the bonding surface of adhesive material 212. When the bonding surface of a different adhesive material is attached to the bonding surface of adhesive material 212, the graphite layer is removed because the adhesive force of the adhesive material is stronger than the bonding force between the graphite layers.

[0127] Since this allotrope D of carbon consists of graphite powder from which layers have been exfoliated, it acquires high thermal conductivity.

[0128] In other words, the carbon allotrope D, from which the carbon layer has been separated, is fixed in contact with the outer surface of the cooling rod 210 by the adhesive material 212 and has high thermal conductivity, thereby increasing the cooling efficiency of the cooling rod 210.

[0129] In this case, it is preferable to use graphene among the various types of allotropes of carbon. Graphene refers to the allotropes of carbon that are separated into a single layer when graphite is peeled off by the adhesive force of the adhesive material. Such graphene has a two-dimensional planar structure in which carbon atoms are linked to each other in a hexagonal honeycomb shape, and therefore consists of a single layer and has high thermal conductivity.

[0130] The cooling rod 210 configured in this way is cooled by the Peltier element 211, and the adhesive material 212 to which the carbon allotrope D is bonded adheres to the cooling rod 210, thereby increasing the cooling efficiency.

[0131] In this case, the portion of the cooling rod 210 to which the adhesive material 212 is attached has a relatively high temperature because the release of cold air is restricted by the adhesive material 212, but cold air is released from the portion to which the adhesive material 212 is not attached and from the through holes 2121 formed in the adhesive material 212, resulting in increased cooling efficiency compared to conventional cooling rods.

[0132] The heat dissipation section 220 consists of a cross-shaped first heat sink 221, a square flat second heat sink 222, and a heat dissipation fin structure 223.

[0133] In this case, it is preferable that the first heat sink 221 and the second heat sink 222 be made of copper, silver, graphene, or other materials that have a higher thermal conductivity than aluminum, which is used in existing heat sinks.

[0134] The first heat sink 221 is formed from a cross-shaped plate material and is installed directly below the Peltier element 211, with its upper surface in contact with the Peltier element 211.

[0135] Furthermore, at the end of the first heat sink 221, an upward-facing inclined plate 2211 and a downward-facing inclined plate 2212 are connected in a cross-sectional manner. This increases the surface area of ​​the first heat sink 221, thereby increasing its heat dissipation efficiency.

[0136] Such a first heat sink 221 releases hot air while idle via an upward-sloping plate 2211 and a downward-sloping plate 2212 connected to its terminal end, and any hot air that is not released is transferred to a second heat sink 222 located directly below it.

[0137] In this case, when the first heat sink 221 is installed, its end portion is positioned to protrude outward from the second heat sink 222, so that the heat from the end portion is not transferred to the second heat sink 222 and is instead dissipated during standby.

[0138] Furthermore, although the first heat sink 221 was described as being formed in a cross shape with an upward-facing inclined plate 2211 and a downward-facing inclined plate 2212 connected to its ends to increase the surface area, the shape of the first heat sink 221 is not limited to this, and may consist of various shapes to increase the surface area.

[0139] The second heat sink 222 is formed in a square, flat shape, with its upper surface in contact with the lower surface of the first heat sink 221 and its lower surface in contact with the upper surface of the heat sink fin structure 223.

[0140] In this case, the second heat sink 222 is formed with a larger area than the upper plate 2231 of the heat sink fin structure 223, and when assembled, it is installed so as to cover the upper plate 2231 of the heat sink fin structure 223.

[0141] This second heat sink 222 plays a role in discharging hot air while the unit is idle, as well as transferring hot air from the first heat sink 221 to the heat sink fin structure 223.

[0142] Furthermore, a powder insertion groove 2221 is formed on the upper surface of the second heat sink 222, and an allotrope of carbon D is inserted into the powder insertion groove 2221.

[0143] In this case, the inserted carbon allotrope D has high thermal conductivity, so the heat from the first heat sink 221 is quickly transferred to the second heat sink 122, increasing the heat dissipation efficiency.

[0144] The heat dissipation fin structure 223 consists of a square, flat upper plate 2231 and a plurality of heat dissipation fins 2232 connected to the lower surface of the upper plate 2231.

[0145] The upper plate 2231 is formed in a square, flat shape, and a powder insertion groove 22311 into which an allotrope of carbon D is inserted is formed on the upper surface, and the allotrope of carbon D is inserted into the inside of the powder insertion groove 22311.

[0146] In this case, the inserted carbon allotrope D has high thermal conductivity, so the heat from the second heat sink 222 is quickly transferred to the upper plate 2231, increasing the heat dissipation efficiency.

[0147] Furthermore, multiple flat heat dissipation fins 2232 are vertically connected to the underside of the upper plate 2231 of the heat dissipation fin structure 223.

[0148] This heat dissipation fin structure 223 receives hot air from the second heat dissipation plate 222 via the upper plate 2231, and the heat transfer rate is increased by the carbon allotrope D inserted in the powder insertion groove 22311, thereby increasing the heat dissipation efficiency.

[0149] Furthermore, the heat dissipation fin structure 223 releases the hot air transferred from the second heat dissipation plate 222 through the heat dissipation fins 2232 while in standby mode.

[0150] The heat dissipation section 220, configured in this way, first releases the hot air from the Peltier element 211 through the cross-shaped first heat sink 221 while in standby mode, and then releases the remaining hot air through the second heat sink 122 and the heat dissipation fin structure 223 while in standby mode.

[0151] As a result, the heat dissipation section 220 can not only reduce the cost of the equipment by reducing the area of ​​the first heat sink 221 and the second heat sink 222, which are made of relatively expensive materials, but also increase the cooling efficiency by increasing the surface area.

[0152] The cooling fan 230 is installed below the heat dissipation fin structure 223 and cools the heat dissipation fin structure 223, thereby allowing the hot air from the Peltier element 211 to be discharged to the outside more quickly, and ensuring that the cooling process of the cooling rod 210 proceeds smoothly.

[0153] In the second cooling device 200 configured in this way, the cooling rod 210 is inserted into a cooling rod through-hole 241 formed in the storage chamber 240, and the object to be cooled stored inside the storage chamber 240 is cooled, and the cooling efficiency is increased by the carbon allotrope D that adheres to the outer surface of the cooling rod 210.

[0154] Furthermore, the second cooling device 200 has an increased area due to the first heat sink 221 and the second heat sink 222 installed between the heat dissipation fin structure 223 and the Peltier element 211, thereby increasing its heat dissipation efficiency.

[0155] Figure 9 is a cross-sectional view of a third cooling device, which is a third embodiment of the first cooling device shown in Figure 2.

[0156] The third cooling device 300 consists of a cooling rod 310, a heat dissipation section 320, a cooling fan 330, a cooling auxiliary ring 340, and a cooling tube body 350.

[0157] In this case, the cooling rod 310, heat dissipation unit 320, and cooling fan 330 have the same shape and structure as the cooling rod 210, heat dissipation unit 220, and cooling fan 230 shown in Figure 6.

[0158] Such a third cooling device 300 is a device in which the cooling efficiency is increased by further installing a cooling auxiliary ring 340 and a cooling tube body 350 on the outside of the cooling rod 310 to increase the cooling efficiency.

[0159] The cooling assist ring 340 is formed in a ring shape with a space formed inside, and the cooling rod 310 is installed by passing through the hollow inside, and when installed, the lower end is installed so as to be in contact with the bottom surface of the storage chamber 240.

[0160] At this time, the cooling auxiliary ring 340 is installed so that its inner surface is in contact with the outer surface of the cooling rod 310, and its internal space is filled with water.

[0161] Such a cooling auxiliary ring 340 is positioned adjacent to the Peltier element 311 when the cooling of the cooling rod 310 begins. As a result, the water filled inside cools quickly and ice forms, and the inner surface comes into contact with the cooling rod 310. This configuration ensures that the cooling of the cooling rod 310 is carried out not only by the Peltier element 311 but also by the cooling auxiliary ring 340.

[0162] Furthermore, the cooling assist ring 340 absorbs the heat of fusion and prevents the internal temperature of the storage chamber from rising for a certain period of time, even when the operation of the Peltier element 311 is interrupted due to a power outage or the like.

[0163] For the sake of explanation, the cooling assist ring 340 was described as being filled with water, but instead of water, a cooling assist solution may be filled inside.

[0164] The cooling tube 350 is formed in a circular tubular shape with a closed top and is made of loess, but salt is added to the inside during the manufacturing process to suppress mold growth caused by moisture.

[0165] In this explanation, for the sake of clarity, the cooling tube 350 was described as being made of yellow clay. However, the materials used to manufacture the cooling tube 350 are not limited to this, and it may be made from a variety of materials such as charcoal and ceramics.

[0166] Furthermore, by filling the inside of the cooling tube 350 with carbon allotrope D, it is not only rapidly cooled by the cold air released from the cooling rod 310, but the amount of temperature increase due to heat flowing in from the outside is also reduced.

[0167] Furthermore, in the case of the cooling rod 310, since it is cooled by the Peltier element 311 attached to its lower end, a temperature difference occurs between the lower and upper ends, resulting in the problem of uneven cooling of the object to be cooled inside the storage chamber 240.

[0168] The cooling tube 350 is cooled by the cold air released from the cooling rod 310 and is configured to be cooled uniformly by the carbon allotrope D filled inside, thereby preventing the objects to be cooled inside the storage chamber 240 from being cooled unevenly.

[0169] Furthermore, the cooling tube body 350 prevents the object to be cooled from being supercooled by preventing it from coming into direct contact with the cooling rod 310, thereby preventing damage and deformation of the object to be cooled due to supercooling.

[0170] Figure 10 is a perspective view of the fourth cooling device, which is a fourth embodiment of the first cooling device shown in Figure 2.

[0171] The fourth cooling device 400 is a device that lowers the temperature of the mat by circulating cooled water through a circulation pipe installed inside the mat.

[0172] As shown in Figure 10, the fourth cooling device 400 consists of a mat section 410 in which a circulation pipe 411 is installed and chilled water is circulated, and a chilled water circulation section 420 that cools the water and circulates the chilled water inside the circulation pipe 411.

[0173] As shown in Figure 10, the mat section 410 is a mat in which a circulation pipe 411 is installed inside.

[0174] The circulation pipe 411 is connected to the chilled water circulation section 420 and configured to circulate chilled water inside, which lowers the temperature of the mat section 410.

[0175] At this time, an allotrope of carbon (not shown) is inserted into the interior of the mat portion 410.

[0176] Allotropes of carbon consist of graphite powder with separated layers.

[0177] Graphite is an allotrope of carbon with excellent thermal and electrical conductivity, and it consists of multiple layers.

[0178] Such graphite exhibits anisotropy, where the thermal conductivity in the planar direction of each layer is higher than the thermal conductivity in the layer direction.

[0179] In other words, graphite has relatively low thermal conductivity in the layer direction, and as the number of layers increases, the thermal conductivity decreases. Therefore, reducing the number of layers can increase the thermal conductivity.

[0180] One method used to separate the graphite layer is a physical delamination method that involves using tape to peel off the graphite layer.

[0181] The physical method used to remove graphite in this case involves attaching powdered graphite to the bonding surface of two adhesive materials. When the bonding surface of one adhesive material is attached to the bonding surface of another adhesive material, the adhesive force of the adhesive material is stronger than the bonding force between the graphite layers, causing the graphite layer to peel off.

[0182] Since these allotropes of carbon consist of graphite powder from which layers have been exfoliated, they exhibit high thermal conductivity.

[0183] In other words, the carbon allotrope from which the carbon layer has been separated is inserted into the mat portion 410 and has high thermal conductivity, thereby increasing the cooling efficiency of the mat portion 410.

[0184] In this type of mat section 410, the temperature is lowered by the cold water circulating inside the circulation pipe 411, which not only lowers the body temperature of the user using the mat section 410, but the cooling efficiency is also increased by the carbon allotropes inserted inside.

[0185] Figure 11 is a cross-sectional view of the chilled water circulation section in Figure 10.

[0186] As shown in Figure 11, the chilled water circulation unit 420 consists of a case 421, a chilled water tank 422 installed inside the case 421 and containing chilled water, and a cooling unit 423 that cools the water contained inside the chilled water tank 422.

[0187] The case 421 is formed in the shape of a box with an internal space, and a chilled water tank 422, a cooling unit 423, and a motor (not shown) are installed inside.

[0188] Furthermore, a water outlet 4211 and a water recovery unit 4212, which are connected to a chilled water tank 422, are installed on the front of the case 421.

[0189] The water outlet 4211 is connected to one end of the circulation pipe 411, and a motor (not shown) discharges the chilled water contained inside the chilled water tank 422 into the circulation pipe 411.

[0190] The recovery unit 4212 is connected to the other end of the circulation pipe 411, and the chilled water discharged from the outlet unit 4211 into the circulation pipe 411 is recovered.

[0191] Additionally, an exhaust plate 4213 is installed on the rear surface of case 421.

[0192] The discharge plate 4213 is formed in the shape of a plate, but multiple discharge holes 42131 are formed by diagonal lines.

[0193] Such an exhaust plate 4213 is designed to allow the hot air from the heat dissipation plate structure 4234 of the cooling unit 423, which will be described later, to be released to the outside.

[0194] The chilled water tank 422 is formed in the shape of a box with a space for storing water inside, and the water stored inside is cooled by the cooling unit 423.

[0195] In this configuration, the chilled water tank 422 is installed adjacent to the front of the case 421, and its rear surface is installed at a distance from the discharge plate 4213 of the case 421. This creates a space between the rear surface of the chilled water tank 422 and the discharge plate 4213 of the case 421 for installing the cooling unit 423 and the motor (not shown).

[0196] In addition, an insulating material 4221 is installed on the outside of the chilled water tank 422.

[0197] The insulation material 4221 is installed to enclose the chilled water tank 422, preventing the cold air from the chilled water tank 422 from being released to the outside, and also preventing the hot air from the heat dissipation plate structure 4234 from flowing into the chilled water tank 422.

[0198] Such insulation material 4221 prevents cold air from the chilled water tank 422 from being released to the outside and prevents hot air from the heat sink structure 4234 or the outside from flowing into the chilled water tank 422. This not only increases the cooling efficiency of the water contained inside the chilled water tank 422, but also ensures that the chilled state of the chilled water is maintained for a long period of time even when the cooling of the cooling unit 423 is interrupted.

[0199] Furthermore, a through-hole 4222 is formed on the rear surface of the chilled water tank 422, through which the cooling rod 4231, described later, passes.

[0200] Figure 12 is a perspective view of the cooling section shown in Figure 11.

[0201] As shown in Figure 12, the cooling unit 423 consists of a cooling rod 4231, a cooling tube 4232, a thermoelectric element 4233, a heat sink structure 4234, and a cooling fan 4235, all of which are installed inside the chilled water tank 422.

[0202] The cooling rod 4231 is formed in the shape of a circular rod by stacking multiple ice buckets 42311, and is installed inside the chilled water tank 422 by passing through a through hole 4222 formed in the chilled water tank 422. A thermoelectric element 4233 is attached to the rear end of the cooling rod 4231.

[0203] In this configuration, the cooling rod 4231 has an allotrope of carbon D inserted between the ice buckets 42311. Since the allotrope of carbon D has high thermal conductivity, the cold air from the ice bucket located at the rear end is quickly transferred to the ice bucket located at the front.

[0204] The ice bucket 42311 is formed in a cylindrical shape with a space formed inside, and inlet holes 423111 for water to flow into are formed on the outer surface at intervals in the circumferential direction.

[0205] Furthermore, because the inner wall surface of the ice bucket 42311 is made of a material with high thermal conductivity, when cooling is carried out by the thermoelectric element 4233, the temperature of the inner wall surface decreases faster than that of water, and ice begins to form from the inner wall surface where the temperature is lower, so that the inside is filled with ice.

[0206] At this time, a thermoelectric element 4233 is attached to the rear surface of the ice bucket 4231 that is positioned at the very rear (hereinafter referred to as the "rearmost ice bucket"). This allows the cold air from the thermoelectric element 4233 to be directly transmitted, enabling the chilled water tank 422 to be sufficiently cooled to a temperature suitable for ice formation, even when the internal temperature of the chilled water tank 422 is high.

[0207] As a result, even when the external temperature of case 421 rises to 30-40°C or higher, the rearmost ice bucket is cooled to below 0°C by the thermoelectric element 4233, and ice is generated inside. In addition, the ice bucket positioned in front of the rearmost ice bucket is cooled to below 0°C by the ice generated inside the rearmost ice bucket and the cold air transmitted from the thermoelectric element 4233, and ice is generated inside it.

[0208] The cooling rod 4231 configured in this way is cooled by the thermoelectric element 4233 attached to the rear surface of the rearmost ice bucket, generating ice inside. The cold air from the thermoelectric element 4233 and the ice formed inside the rearmost ice bucket is transmitted forward, causing ice to be sequentially formed inside the ice buckets positioned in front of the rearmost ice bucket. As a result, ice is formed inside the ice buckets 42311 even when the external temperature is high.

[0209] Furthermore, because ice forms inside the ice bucket 42311, the cooling rod 4231 maintains a temperature below a certain level, thereby cooling the water contained in the chilled water tank 422 to a certain temperature.

[0210] Furthermore, the cooling rod 4231 is positioned in the front-to-back direction inside the chilled water tank 422, increasing the contact area with the water contained inside the chilled water tank 422. This allows for simultaneous cooling of a wide area, increasing the cooling rate and enabling uniform cooling of the water contained inside.

[0211] The cooling tube 4232 is a rod-shaped tube with a cooling aid solution and cotton inserted inside. One end is connected to the rear surface of the chilled water tank 422, and the outer surface is in contact with the outer surface of the cooling rod 4231.

[0212] At this time, the cooling aid solution filled inside the cooling tube 4232 is a solution consisting of 70-80% by weight of acetic acid and 20-30% by weight of salt.

[0213] Since the cooling aid solution has high thermal conductivity and heat capacity when a salt is dissolved in acetic acid, the thermal conductivity and heat capacity of the cooling tube 4232 into which the cooling aid solution is inserted increase, thereby increasing the cooling efficiency.

[0214] Furthermore, since the cooling aid solution is absorbed by cotton and inserted into the cooling tube 4232, its shelf life is longer than when it is inserted in liquid form.

[0215] Such cooling aid solutions not only have high thermal conductivity but also large heat capacity, so even when the external temperature drops, they maintain a cooling state for a long time, and even when the cooling of the thermoelectric element 4233 is interrupted due to a power outage or malfunction, they maintain the cooling state of the cooling tube 4232, thereby increasing the time it takes for the temperature of the cooling rod 4231, which is installed in contact with the cooling tube 4232, to rise.

[0216] Since such a cooling tube 4232 is installed in contact with the outer surface of the cooling rod 4231, the cooling auxiliary solution filled inside is cooled by the cooling rod 4231.

[0217] Since the cooling tube 4232 configured in this way is installed in contact with the outer surface of the cooling rod 4231, the cooling auxiliary solution filled inside is cooled by the cold air from the cooling rod 4231.

[0218] In this case, the cooling auxiliary solution not only has high thermal conductivity but also a large heat capacity, so even if the external temperature drops, the cooling state is maintained for a long time. Therefore, even if the cooling of the thermoelectric element 4233 is interrupted due to a power outage, malfunction, etc., the cooling state of the cooling tube 4232 is maintained, and the rate at which the temperature of the water contained inside the chilled water tank 422 rises can be reduced.

[0219] The thermoelectric element 4233 is an element that operates on the principle that when an electric current flows, one side is cooled and the other side is heated.

[0220] One side of the thermoelectric element 4233 is attached to the rear end of the cooling rod 4231 to cool the cooling rod 4231, and the other side is attached to the front surface of the heat sink structure 4234 to heat the heat sink structure 4234.

[0221] The heat sink structure 4234 consists of a flat heat sink frame 42341 on which a thermoelectric element 4233 is attached to the front surface, and a plurality of flat heat sinks 42342 that are perpendicularly coupled to the rear surface of the heat sink frame 42341.

[0222] This heat sink structure 4234 receives hot air generated from the thermoelectric element 4233 via the heat sink frame 42341 and releases the hot air via the heat sink 42342 while in standby mode.

[0223] The cooling fan 4235 is installed below the heat sink structure 334 and expels the hot air from the heat sink structure 4234 to the outside via the exhaust plate 4213 installed on the rear surface of the case 421. This further expels the hot air from the thermoelectric element 4233 to the outside, ensuring a smooth cooling process for the cooling rod 4231.

[0224] In the cooling unit 423 configured in this way, the cooling rod 4231, which is placed inside the chilled water tank 422, is cooled by a thermoelectric element 4233 attached to its rear end, so that ice is generated sequentially in the ice bucket 3311 of the cooling rod 4231 from rear to front.

[0225] Such a cooling rod 4231 is kept at a temperature below a certain level by the ice generated inside, and not only cools the water, but by being positioned in the front-to-back direction inside the chilled water tank 4232, the contact area with the water is increased, allowing the water contained inside the chilled water tank 4232 to be cooled uniformly.

[0226] Furthermore, the cooling unit 423 has an allotrope of carbon D inserted between the ice buckets 42311, which accelerates the transfer rate of cold air generated between the ice buckets 42311, thereby reducing the time it takes for ice to form in the ice bucket located at the very front.

[0227] Furthermore, even if the cooling of the thermoelectric element 4233 is interrupted due to a power outage, malfunction, or the like, the cooling unit 423 maintains cool air for a long period of time thanks to the ice generated inside the cooling rod 4231 and the cooling auxiliary solution filled inside the cooling tube 4232, allowing the water contained inside the chilled water tank 422 to remain cold for an even longer period.

[0228] Figure 13 is a perspective view of the second cooling unit, which is a second embodiment of the cooling unit in Figure 12, and Figure 14 is a cross-sectional view of Figure 13.

[0229] As shown in Figure 13, the second cooling section 433 consists of a second cooling rod 4331, a second cooling tube 4332, a second thermoelectric element 4333, a heat sink structure 4334, a cooling fan 4335, and a cold air transfer section 4336.

[0230] In this case, the heat sink structure 4334 and cooling fan 4335 of the second cooling unit 433 have the same shape and structure as the heat sink structure 4334 and cooling fan 4335 of the cooling unit 423 shown in Figure 12.

[0231] The second cooling rod 4331 is formed in the shape of a circular rod by stacking multiple ice buckets 43311, and is installed inside the chilled water tank 422 by passing through a through hole 4222 formed in the chilled water tank 422. At this time, an allotrope of carbon D is inserted between the ice buckets 43311 in the second cooling rod 4331.

[0232] The ice bucket 43311 is formed in a cylindrical shape with a space formed inside, and on its outer surface, an inlet hole 433111 through which water flows in and a cooling tube through-hole 433112 through which the second cooling tube 4332 passes are formed at intervals in the circumferential direction.

[0233] At this time, the second cooling tubes 4332 are installed by passing through the cooling tube through holes 433112 formed in the ice bucket 43311, and the second cooling tubes 4332 are positioned inside the ice bucket 43311.

[0234] The second cooling tube 4332 is a rod-shaped tube filled with a cooling aid solution, and is installed to be placed inside the ice bucket 43311.

[0235] At this time, the second cooling tube 4332 is formed to have a diameter equal to the diameter of the cooling tube through hole 433112 formed on the outer surface of the ice bucket 43311, and when inserted, the cooling tube insertion hole 433112 is sealed by the second cooling tube 4332.

[0236] Furthermore, when the second cooling tube 4332 is installed, the portion adjacent to its outer end is connected to the cold air transfer section 4336, and the inner end is positioned inside the ice bucket 43311.

[0237] Since this second cooling tube 4332 is connected to the cold air transfer unit 4336, it is cooled by cold air transferred from the connected cold air transfer unit 4336 and is placed inside the ice bucket 43311, so the ice bucket 43311, which is installed at a distance from the second thermoelectric element 4333, is also cooled quickly.

[0238] Furthermore, since the second cooling tube 4332 is filled with a cooling auxiliary solution with a large heat capacity, even when the supply of cold air is interrupted due to a power outage or malfunction, it can maintain the cold air for a long period of time and prevent the temperature of the water contained inside the chilled water tank 422 from rising rapidly.

[0239] The second thermoelectric element 4333 is attached to the rear surface of the cooling plate 43361 of the cold air transfer section 4336, and transfers cold air to the cooling plate 43361.

[0240] The cold air transfer section 4336 consists of a disc-shaped cooling plate 43361 and a plurality of contact plates 43362 connected to the cooling plate 43361.

[0241] The cooling plate 43361 is formed in a plate shape, with its front surface connected to the rear surface of the second cooling rod 4331, and the second thermoelectric element 4333 attached to its rear surface.

[0242] In this case, it is preferable that the diameter of the cooling plate 43361 is formed to be larger than the diameter of the cooling rod 4331.

[0243] Furthermore, it is preferable that the cooling plate 43361 be made of a material with high thermal conductivity in order to quickly diffuse the cold air from the second thermoelectric element 4333.

[0244] Furthermore, contact plates 43362 protrude forward from the front surface of the cooling plate 43361 at intervals in the circumferential direction from the outer edge.

[0245] The contact plate 43362 is formed in the shape of a curved plate having the same curvature as the outer surface of the second cooling rod 4331, and its rear end is connected to the front surface of the cooling plate 43361.

[0246] In this configuration, the contact plate 43362 is installed with its inner circumferential surface in contact with the outer circumferential surface of the second cooling rod 4331, and its length in the front-to-back direction is formed to be the same as or smaller than the length of the second cooling rod 4331, so that its inner circumferential surface is also installed in contact with the outer circumferential surface of the ice bucket 43311 located at the very front.

[0247] Furthermore, the contact plate 43362 has a double-wall structure consisting of an inner wall 433621 that contacts the outer surface of the second cooling rod 4331 when installed, and an outer wall 433622 that is installed to enclose the inner wall 433621 from the outside, preventing the inner wall 433621 from coming into direct contact with water.

[0248] In this state, the contact plate 43362 has an inner wall 433621 made of a material with high thermal conductivity, which is rapidly cooled by the cold air released from the cooling plate 43361, while the outer wall 433622 is made of a material with low thermal conductivity, which is relatively higher in temperature than the inner wall 433621.

[0249] Furthermore, the contact plate 43362 has a cooling tube coupling hole 433623 formed through the inner wall 433621 and the outer wall 433622, which connects to the second cooling tube 4332.

[0250] At this time, the cooling tube connection hole 433623 is formed at a position corresponding to the cooling tube through hole 433112 formed in the second cooling rod 4331.

[0251] The contact plate 43362 is configured to uniformly transfer the cold air from the second thermoelectric element 4333 to the cooling rod 4331 via the inner wall 433621, which has high thermal conductivity, thereby ensuring that the second cooling tube 4332 connected to the cooling tube coupling hole 433623 and the second cooling rod 4331 in contact with the inner wall 433621 are uniformly cooled.

[0252] The second cooling unit 433, configured in this way, is configured such that when cold air is generated by the second thermoelectric element 4333, the cold air generated from the second thermoelectric element 4333 is uniformly transmitted to the second cooling rod 4331 via the cold air transmission unit 4336. This increases the rate at which ice is generated inside the ice bucket 43311 that constitutes the second cooling rod 4331.

[0253] Furthermore, the second cooling unit 433 is configured such that a second cooling tube 4332 filled with a cooling auxiliary solution is placed inside the ice bucket 43311. This increases the time it takes for the ice generated inside the ice bucket 43311 to melt, ensuring that even if the cooling of the second thermoelectric element 4333 is interrupted due to a malfunction or power outage, cooling can continue for an extended period.

[0254] Figure 15 is a cross-sectional view of the fifth cooling device, which is a fifth embodiment of the first cooling device in Figure 2, and Figure 16 is a cross-sectional view of the cooling section and ice generation section in Figure 15.

[0255] As shown in Figure 15, the fifth cooling device 500 consists of a case 520, a storage chamber 530, a cooling section 540, a drainage section 550, and an ice generation section 560.

[0256] In this case, the case 520, storage chamber 530, and drainage section 550 of the fifth cooling device 500 have the same shape and structure as the case 120, storage chamber 130, and drainage section 150 of the first cooling device 100 in Figure 2.

[0257] As shown in Figure 16, the cooling section 540 consists of a cooling rod 541, a heat sink structure 542, a cooling fan 543, and a pipe 544.

[0258] In this case, the heat sink structure 542 and the cooling fan 543 have the same shape and structure as the heat sink structure 142 and the cooling fan 143 of the first cooling device 100 in Figure 2.

[0259] The cooling rod 541 is formed in the shape of a circular rod with a space formed inside, and a Peltier element 5411 is attached to its lower surface.

[0260] Furthermore, an adhesive material 5412, on which an allotrope of carbon D is attached to the adhesive surface, is attached to the inner circumferential surface of the cooling rod 541 in the longitudinal direction of the cooling rod 541.

[0261] In such a cooling rod 541, the allotrope D of carbon attached to the adhesive material 5412 is configured to come into direct contact with the outer surface of the cooling rod 541, thereby increasing the cooling efficiency due to the allotrope D of carbon.

[0262] The tube 544 is formed in a circular tubular shape with a closed top and is installed enclosing the cooling rod 541.

[0263] Furthermore, the pipe body 544 has multiple through holes 5441 formed therein, configured to allow water to flow in and out.

[0264] The ice-generating section 560 has a shape in which multiple rings 561, each with a space formed inside, are stacked.

[0265] In this configuration, the ice generation unit 560 is installed adjacent to the lower end of the cooling rod 541, thereby being installed adjacent to the Peltier element 5411.

[0266] Furthermore, the ice generating unit 560 is filled with water inside the ring 561.

[0267] In this ice generation unit 560, when the cooling of the cooling rod 541 is started by the Peltier element 5411, ice is sequentially generated inside the ring 561, starting from the ring adjacent to the Peltier element 5411, and the generated ice cools the cooling rod 540. As a result, the cooling rod 541 is cooled not only by the Peltier element 5411 but also by the ice generated inside the ice generation unit 560, increasing the cooling rate of the cooling rod 541.

[0268] Furthermore, since ice is generated inside the ice generation unit 560, even if the cooling of the cooling rod 541 by the Peltier element 5411 is interrupted due to a power outage or malfunction, the ice generated inside prevents the internal temperature of the cooling rod 541 and the storage chamber from rising for a certain period of time.

[0269] For the sake of explanation, it was stated that the ice-generating section 560 is filled with water, but a cooling aid solution may be filled instead of water.

[0270] The fifth cooling device 500, configured in this way, has the same structure as the first cooling device 100, but since an adhesive material 5412 with an allotrope of carbon 541 attached to the inner surface of the cooling rod 541 is attached, the cooling efficiency is increased compared to the first cooling device 100.

[0271] Furthermore, the fifth cooling device 500 is configured such that an ice generating unit 560 is installed at the bottom of the cooling rod 541, and the cooling of the cooling rod 541 is carried out by the ice generated inside the ice generating unit 560. This not only increases the cooling rate of the cooling rod 541, but also ensures that even if cooling is interrupted due to a power outage or malfunction, the ice generated inside the ice generating unit 560 maintains the coolness for a long period of time.

[0272] Figure 17 is a cross-sectional view of the sixth cooling device, which is a sixth embodiment of the first cooling device shown in Figure 2.

[0273] As shown in Figure 17, the sixth cooling device 600 consists of a cooling rod 610, a heat dissipation section 620, a cooling fan 630, and a cooling tube body 650.

[0274] In this case, the heat dissipation section 620 and the cooling fan 630 in the sixth cooling device 600 have the same shape and structure as the heat dissipation section 220 and the cooling fan 230 in Figure 6.

[0275] The cooling rod 610 is formed in the shape of a circular rod, and a Peltier element 611 is attached to its lower surface.

[0276] Furthermore, an adhesive material 612, on which an allotrope of carbon D is attached to the adhesive surface, and a fixing band 613 that encloses the adhesive material 612 are installed on the outer surface of the cooling rod 610.

[0277] The adhesive material 612 is formed in the shape of a strip with an adhesive surface on one side, and is attached in a ring shape to the outer surface of the cooling rod 610, with multiple pieces attached at intervals in the vertical direction.

[0278] Furthermore, when the adhesive material 612 is attached, the carbon allotrope D is attached to the adhesive surface, and the adhesive material 612 is attached to the outer surface of the cooling rod 610, causing the carbon allotrope D and the outer surface of the cooling rod 610 to come into close contact. As a result, the cooling rod 610 comes into close contact with the carbon allotrope D, which has high thermal conductivity, and the cooling efficiency increases.

[0279] The fixing band 613 is formed in the shape of a plastic strip and is installed by wrapping around the adhesive material 612 attached to the outer surface of the cooling rod 610.

[0280] Such a fixing band 613 prevents the adhesive material 612 from separating from the cooling rod 610 when the adhesive strength of the adhesive material 612 decreases due to prolonged use.

[0281] Furthermore, multiple cooling aid solution insertion grooves 614 are formed on the upper surface of the cooling rod 610.

[0282] The cooling auxiliary solution insertion grooves 614 are formed on the upper surface of the cooling rod 610, and a plurality of them are formed at intervals.

[0283] In addition, the inside of the cooling auxiliary solution insertion grooves 614 is filled with cotton and a solution in which salt is dissolved in acetic acid.

[0284] The cotton is inserted into the inside of the cooling auxiliary solution insertion grooves 614 in a state of absorbing the solution in which salt is dissolved in acetic acid.

[0285] At this time, since the solution in which salt is dissolved in acetic acid has high thermal conductivity, the cooling efficiency of the cooling rod 610 is increased.

[0286] In addition, since the solution in which salt is dissolved in acetic acid is absorbed by the cotton, the storage period is longer than when it exists in a liquid state.

[0287] The sixth cooling device 600 configured as described above has the same structure as the second cooling device 200, but by wrapping the adhesive material 612 attached to the outer peripheral surface of the cooling rod 610 and further installing the fixing band 613, it is possible to prevent the adhesive material 612 attached to the cooling rod 610 from being separated from the cooling rod 610.

[0288] In addition, the sixth cooling device 600 is configured by inserting cotton in which a solution in which salt is dissolved in acetic acid is absorbed into the cooling auxiliary solution insertion grooves 614 formed in the cooling rod 610, so that the cooling efficiency of the cooling rod 610 is increased by the cotton in which the solution in which salt is dissolved in acetic acid is absorbed.
