- the storage chamber 120 may be cooled by operating the thermoelectric element.
- the heat generating side In order to sufficiently cool the heat absorbing side of the thermoelectric element, the heat generating side should be smoothly generated. If the temperature difference between the heat absorbing side and the heat generating side is constant, the lower the temperature on the heat generating side may also lower the temperature on the heat absorbing side.
- the present invention proposes a refrigerator 100 including a heat dissipation cover 160 and a support 170 for smooth heat dissipation on the heating side.
- the heat dissipation cover 160 is coupled to the back of the outer case 112.
- the heat dissipation cover 160 may be provided with a stopper 163.
- the support 170 is installed on the bottom of the cabinet 110 to support the cabinet (110).
- the cooler for cooling the storage compartment 120 is implemented as a refrigeration cycle device including a compressor, a condenser, an expander, and an evaporator, it is difficult to fundamentally block vibrations and noise generated from the compressor.
- the installation place of the refrigerator such as a cosmetic refrigerator, is not limited to the kitchen but is expanded to the living room or the bedroom, etc., if noise and vibration are not blocked at the source, it causes great inconvenience to the refrigerator user.
- thermoelectric elements do not generate noise and vibration unlike compressors. Therefore, if the thermoelectric element is applied to the refrigerator 100, even if the refrigerator is installed in a space other than the kitchen, it is possible to solve the problem of noise and vibration.
- thermoelectric element is smaller in size than the refrigeration cycle apparatus, the refrigerator 100 to which the thermoelectric element is applied may have a smaller size than the refrigerator having the refrigeration cycle apparatus. For this reason, a thermoelectric element is more advantageous than the refrigeration cycle device in the built-in refrigerator 100.

- the thermoelectric module 150 operates between the first and second regions which are separated from each other, and absorbs heat in one region and radiates heat in the other region.
- the first area and the second area refer to areas that are spatially separated from each other by a boundary. If the thermoelectric module 150 is applied to the refrigerator (100 of FIG. 1), the first region corresponds to one of the storage compartment and the outside of the refrigerator, and the second region corresponds to the other.
- thermoelectric element 151 is formed by forming a PN junction with a P-type semiconductor and an N-type semiconductor, and connecting a plurality of PN junctions in series.
- the thermoelectric element 151 includes a heat absorbing portion 151a and a heat radiating portion 151b facing in opposite directions.
- the heat absorbing portion 151a and the heat dissipating portion 151b may be formed in a shape capable of surface contact. Accordingly, the heat absorbing portion 151a may be referred to as a heat absorbing surface, and the heat radiating portion 151b may be referred to as a heat radiating surface.
- the heat absorbing portion 151a and the heat dissipating portion 151b may be generically named as the first and second portions, or may be named as the first and second surfaces. This nomenclature is for convenience of description only and does not limit the scope of the invention.
- the first heat sink 152 is disposed to contact the heat absorbing part 151a of the thermoelectric element 151.
- the first heat sink 152 is configured to heat exchange with the first region.
- the first region corresponds to a storage compartment of the refrigerator (120 of FIG. 1), and the heat exchange target of the first heat sink 152 is air inside the storage compartment.
- the first fan 153 is installed to face the first heat sink 152 and generates wind to promote heat exchange of the first heat sink 152. Since heat exchange is a natural phenomenon, even without the first fan 153, the first heat sink 152 may exchange heat with air in the storage compartment. However, as the thermoelectric module 150 includes the first fan 153, heat exchange of the first heat sink 152 may be further promoted.
- the first fan 153 may be wrapped by the cover 154.
- the cover 154 may include a portion other than the portion 154a surrounding the first fan 153.
- a plurality of holes 154b may be formed in the portion 154a surrounding the first fan 153 to allow air in the storage compartment to pass through the cover 154.
- the cover 154 may have a structure that can be fixed to the rear wall (111a of FIG. 1) of the storage compartment.
- a cover 154 includes a portion 154c extending from both sides of a portion 154a surrounding the first fan 153, and a screw fastening hole that can be screwed into the extending portion 154c ( The structure in which 154e is formed is shown.
- the cover 154 since the screw 159c is inserted into a portion surrounding the first fan 153, the cover 154 may be additionally fixed to the rear wall by the screw 159c. Holes 154b and 154d through which air can pass may be formed in the portion 154a surrounding the first fan 153 and the extending portion 154c.
- the second heat sink 155 is disposed to contact the heat radiating part 151b of the thermoelectric element 151.
- the second heat sink 155 is configured to heat exchange with the second region.
- the second area corresponds to a space between the outer case 112 of FIG. 1 and the heat dissipation cover, or corresponds to an outer space of the refrigerator 100 of FIG. 1.
- the heat exchange target of the second heat sink 155 is air outside the outer case.
- the second fan 156 is installed to face the second heat sink 155 and generates wind to promote heat exchange of the second heat sink 155.
- the second fan 156 promotes heat exchange of the second heat sink 155 is the same as the first fan 153 promotes heat exchange of the first heat sink 152.
- the first fan 153 and the second fan 156 may be formed as an axial fan.
- An axial fan corresponds to one type of fan, and is formed to cause wind along the rotation axis of the fan. Since the first fan 153 is disposed to face the first heat sink 152, and the second fan 156 is disposed to face the second heat sink 155, the first fan 153 and the second fan are arranged to face each other.
- the fan 156 is preferably formed of an axial fan. This is because the wind generated in the first fan 153 may be directly supplied to the first heat sink 152, and the wind generated in the second fan 156 may be directly supplied to the second heat sink 155. .
- the second fan 156 may optionally have a shroud 156c.
- the shroud 156c is made to guide the wind.
- the shroud 156c may be configured to surround the vanes 156b at a position spaced apart from the vanes 156b as shown in FIG. 2.
- a screw fastening hole 156d may be formed in the shroud 156c to fix the second fan 156.
- the first heat sink 152 and the first fan 153 correspond to the heat absorbing side of the thermoelectric module 150.
- the second heat sink 155 and the second fan 156 correspond to the heat generating side of the thermoelectric module 150.
- At least one of the first heat sink 152 and the second heat sink 155 includes a base 152a, 155a and fins 152b, 155b, respectively.
- the first heat sink 152 and the second heat sink 155 will be described on the premise that both of the bases 152a and 155a and the fins 152b and 155b are included.
- the bases 152a and 155a are in surface contact with the thermoelectric element 151.
- the base 152a of the first heat sink 152 is in surface contact with the heat absorbing portion 151a of the thermoelectric element 151, and the base 155a of the second heat sink 155 is a heat radiating portion of the thermoelectric element 151.
- the bases 152a and 155a and the thermoelectric element 151 may be in surface contact with each other.
- a thermal grease or a thermal compound may be used to increase thermal conductivity by filling a minute gap between the bases 152a and 155a and the thermoelectric element 151.
- Fins 152b and 155b protrude from base 152a and 155a to exchange heat with air in the first region or air in the second region. Since the first region corresponds to the storage chamber 120 (FIG. 1) and the second region corresponds to the outside of the refrigerator 100 (FIG. 1), the fins 152b of the first heat sink 152 may correspond to the storage chamber (FIG. 1).
- the heat exchanger 120 is configured to exchange heat with the air, and the fins 155b of the second heat sink 155 are configured to exchange heat with external air of the refrigerator (100 of FIG. 1).
- the pins 152b and 155b are spaced apart from each other. This is because the heat exchange area may increase as the fins 152b and 155b are spaced apart from each other. If the fins 152b and 155b are stuck together, there will be no heat exchange area between the fins 152b and 155b, but between the fins 152b and 155b since the fins 152b and 155b are spaced apart from each other. There may also be a heat exchange area in between. Since the thermal conductivity increases as the heat transfer area increases, the area of the fins exposed to the first and second areas should be increased to improve the heat transfer performance of the heat sink.
- the thermal conductivity of the second heat sink 155 corresponding to the heat generating side should be larger than that of the first heat sink 152. This is because sufficient heat absorption is achieved at the heat absorbing portion 151a only when heat is radiated more quickly at the heat radiating portion 151b of the thermoelectric element 151. This is due to the fact that the thermoelectric element 151 is not a simple heat conductor, but an endotherm is made by applying a voltage, and the heat is radiated from the other side. Therefore, sufficient heat dissipation must be made in the heat dissipation unit 151b of the thermoelectric element 151 so that sufficient cooling can be realized in the heat absorbing unit 151a.
- the heat exchange area of the second heat sink 155 is larger than that of the first heat sink 152.
- the heat exchange area must be large. Assuming that all heat exchange areas of the first heat sink 152 are all used for heat exchange, the heat exchange area of the second heat sink 155 is three times or more than the heat exchange area of the first heat sink 152. desirable.
- the air volume and the wind speed formed by the second fan 156 are preferably larger than the air volume and the wind speed formed by the first fan 153.
- the second heat sink 155 requires a larger heat exchange area than the first heat sink 152.
- the area of the base 155a and fins 155b of the second heat sink 155 is larger than those 152a and 152b of the first heat sink 152.
- the second heat sink 155 may be provided with a heat pipe 155c to quickly distribute the heat transferred to the base 155a of the second heat sink 155 to the fins.
- the heat pipe 155c is configured to receive a heat transfer fluid therein, one end of the heat pipe 155c penetrates the base 155a and the other end penetrates the fins 155b.
- the heat pipe 155c is a device that transfers heat from the base 155a to the fins 155b through evaporation of the heat transfer fluid contained therein. Without the heat pipe 155c, heat exchange would be concentrated only in the adjacent fins 155b of the base 155a. This is because heat is not sufficiently distributed to the pins 155b which are far from the base 155a.
- heat exchange may be performed at all the fins 155b of the second heat sink 155. This is because the heat of the base 155a can be evenly distributed to the pins 155b disposed relatively far from the base 155a.
- the base 155a of the second heat sink 155 may be formed of two layers (two layers) 155a1 and 155a2 to embed the heat pipe 155c.
- the first layer 155a1 of the base 155a surrounds one side of the heat pipe 155c
- the second layer 155a2 surrounds the other side of the heat pipe 155c, and has two layers 155a1 and 155a2. May be arranged to face each other.
- the first layer 155a1 may be disposed to be in contact with the heat dissipation unit 151b of the thermoelectric element 151 and may have the same or similar size as the thermoelectric element 151.
- the second layer 155a2 is connected to the pins 155b, and the pins 155b protrude from the second layer 155a2.
- the second layer 155a2 may have a larger size than the first layer 155a1.
- One end of the heat pipe 155c is disposed between the first layer 155a1 and the second layer 155a2.
- the heat insulator 157 is installed between the first heat sink 152 and the second heat sink 155.
- the heat insulator 157 is formed to surround the edge of the thermoelectric element 151.
- a hole 157a may be formed in the heat insulating material 157, and a thermoelectric element 151 may be disposed in the hole 157a.
- thermoelectric element module 150 is a device that realizes cooling of the storage chamber (120 of FIG. 1) through endothermic and heat dissipation formed at one side and the other side of the thermoelectric element 151, but is not a simple thermal conductor. Therefore, it is not preferable that heat of the first heat sink 152 is directly transferred to the second heat sink 155. This is because if the temperature difference between the first heat sink 152 and the second heat sink 155 is reduced due to direct heat transfer, the performance of the thermoelectric element 151 is reduced. In order to prevent this phenomenon, the insulation 157 is configured to block direct heat transfer between the first heat sink 152 and the second heat sink 155.
- the fastening plate 158 is disposed between the first heat sink 152 and the heat insulator 157 or between the second heat sink 155 and the heat insulator 157.
- the fastening plate 158 is for fixing the first heat sink 152 and the second heat sink 155, and the first heat sink 152 and the second heat sink 155 are screwed to each other by the fastening plate ( 158 may be screwed into.

- the fastening plate 158 has a hole 158a corresponding to the thermoelectric element 151 like the heat insulating material 157, and the thermoelectric element 151 may be disposed in the hole 158a.
- the fastening plate 158 is not an essential configuration of the thermoelectric module 150, and may be replaced with another configuration capable of fixing the first heat sink 152 and the second heat sink 155.
- a plurality of screw fastening holes 158b and 158c for fixing the first heat sink 152 and the second heat sink 155 may be formed in the fastening plate 158.
- the first heat sink 152 and the heat insulating material 157 are formed with screw fastening holes 152c and 157b corresponding to the fastening plate 158, and the screws 159a are formed by the three screw fastening holes 152c, 157b and 158b. ) May be sequentially inserted to fix the first heat sink 152 to the fastening plate 158.
- a screw fastening hole 155d corresponding to the fastening plate 158 is formed in the second heat sink 155, and a screw 159b is sequentially inserted into the two screw fastening holes 158c and 155d so that the second heat sink is provided. 155 may be fixed to the fastening plate 158.
- the fastening plate 158 may include a recess 158d configured to receive one side of the heat pipe 155c.
- the recess 158d may be formed to correspond to the heat pipe 155c and partially wrap. Even though the second heat sink 155 includes the heat pipe 155c, since the fastening plate 158 includes the recessed portion 158d, the second heat sink 155 may be in close contact with the fastening plate 158. And, the overall thickness of the thermoelectric module 150 can be made thinner.
- At least one of the first fan 153 and the second fan 156 described above includes hubs 153a and 156a and vanes 153b and 156b. Hubs 153a and 156a are coupled to a central axis of rotation (not shown). Vanes 153b and 156b are radially installed around the hubs 153a and 156a.
- the axial fans 153 and 156 are separated from the centrifugal fan.
- the axial flow fans 153 and 156 are formed to cause wind in the rotation axis direction, and air enters the rotation axis direction of the axial flow fans 153 and 156 and exits in the rotation axis direction.
- the centrifugal fan is formed to cause wind in the centrifugal direction (or circumferential direction), and air enters the centrifugal direction in the direction of the rotation axis of the centrifugal fan.

Therefore, the refrigerator 100 having a thermoelectric module is suitable to be implemented as a built-in refrigerator 100. In FIG. 3, the refrigerator 100 is embedded in the furniture.
- the refrigerator 100 When the refrigerator 100 is surrounded by the shielding film as described above, the refrigerator 100 naturally has a structure vulnerable to heat radiation. Unless a separate cooling system is provided, the heat dissipation side of the thermoelectric element module is cooled by natural convection of air. By the way, if the flow of air to be supplied to the thermoelectric element is blocked by the shielding film, not only is the heat dissipation side of the thermoelectric element not sufficiently radiated, but also the cooling performance of the thermoelectric element is reduced.

- O denotes air discharged to the lower side of the cabinet 110.
- the second fan 156 sucks air outside the heat dissipation cover 160 into the heat dissipation cover 160 to promote heat exchange of the second heat sink 155. Since the second fan 156 is installed to be visually exposed to the outside through the heat dissipation cover 160, when the second fan 156 is rotated, air is sucked into the heat dissipation cover 160. The air sucked into the heat dissipation cover 160 exchanges heat with the second heat sink 155, and receives heat from the second heat sink 155 to become hot. Accordingly, heat dissipation of the second heat sink 155 is performed.
- the second fan 156 is disposed above the center of the heat dissipation cover 160 to suck air through the upper portion of the heat dissipation cover 160.
- the lower part of the heat dissipation cover 160 is the lower one of the two drawers 141 and 142. It is disposed at a height corresponding to 141.
- the upper portion of the heat dissipation cover 160 is disposed at a height corresponding to the upper drawer 142.
- the second fan 156 Since the second fan 156 is disposed above the center of the heat dissipation cover 160, the second fan 156 is disposed at a position facing the upper drawer 142. Accordingly, air is sucked into the heat dissipation cover 160 through the top of the heat dissipation cover 160.

- the heat dissipation cover 160 is formed to block the upper and left and right sides of the opening in which the second fan 156 is installed. Accordingly, the air sucked into the heat dissipation cover 160 by the second fan 156 is naturally guided from the top to the bottom.
- the heat dissipation cover 160 includes a main plate 161 and an edge portion 162.
- the main plate 161 is disposed to be spaced apart from the rear surface of the out case 112. Accordingly, a flow path that guides the flow of air is formed between the rear surface of the outer case 112 and the main plate 161.
- the main plate 161 has an opening at a position facing the second fan 156.
- the second fan 156 is installed to be visually exposed to the outside of the heat dissipation cover 160 through the opening.
- the edge portion 162 protrudes from the edge of the main plate 161 toward the outer case 112 and is coupled to the outer case 112.
- An edge portion 162 is formed at an upper end, a left end, and a right end of the main plate 161, respectively. Since the edge portion 162 serves to shield a flow path through which air enters or leaks, the air introduced into the heat dissipation cover 160 by the second fan 156 may be separated from the rear surface of the outer case 112. It is guided from top to bottom along the flow path between the main plates 161.
- the support 170 is sucked through the second fan 156 to guide the air guided by the heat dissipation cover 160 to the front of the cabinet 110 through the lower side of the cabinet 110.

- the floor may mean a floor on which the refrigerator 100 is installed.
- the floor may mean a partition of the furniture.
- a flow path through which air can be discharged is formed between the cabinet 110 and the floor. Accordingly, air may be discharged toward the front of the cabinet 110 through the lower side of the cabinet 110.
- the support 170 includes a pier 171, a rib 172, and discharge ports 173a and 173b. See FIG. 6 for a detailed structure of the support 170.
- the pier 171 spaces the cabinet 110 from the floor and is formed to support the cabinet 110. In the support 170, if the upper part touches the bottom of the cabinet 110 along the vertical direction and the lower part touches the bottom, the parts correspond to the pier 171.

- the small discharge port 173b corresponds to the sub discharge port 173b.
- the pier 171 supports the cabinet 110, air may be discharged through the discharge holes 173a and 173b formed in the pier 171.
- the ribs 172 are formed to compensate for the decrease in the strength of the support 170 by the discharge ports 173a and 173b.
- the suction port refers to an opening in which the second fan 156 is installed.
- the air inlets and the discharge ports 173a and 173b are spaced apart from each other before and after the refrigerator 100.
- the air inlets and the discharge ports 173a and 173b are disposed on the upper and lower sides of the refrigerator 100. Spaced apart from each other along the direction.
- the air inlets and the air outlets 173a and 173b are spaced apart from each other, according to the structure of the present invention, it is possible to prevent the air discharged from the refrigerator 100 from being re-intakeed into the air inlet again. In addition, when the air is discharged through the lower side of the cabinet 110, it is possible to prevent the hot air is transferred to the face of the user.

- the air introduced through the upper side of the cabinet 110 is sucked into the heat dissipation cover 160 and discharged to the lower side of the cabinet 110, as shown in FIG. Even if it is completely wrapped, there is no problem with the air flow.
- the main plate 161 of the heat dissipation cover 160 In order to intake air, the main plate 161 of the heat dissipation cover 160 should be spaced apart from a shielding film such as furniture. This is because air may not be sucked into the heat dissipation cover 160 when the main plate 161 is in close contact with the shielding film.
- the refrigerator 100 includes a stopper 163 to separate the main plate 161 from the shielding film.
- the stopper 163 protrudes from the heat dissipation cover 160 toward the shielding film disposed at the rear of the refrigerator 100 to separate the heat dissipation cover 160 from the shielding film disposed at the rear of the refrigerator 100. Since the heat dissipation cover 160 is spaced apart from the shielding film by the stopper 163, air may be sucked through the space between the heat dissipation cover 160 and the shielding film.

- the first guide part 568a protrudes from the main plate 561 toward the out case 512 under the opening in which the second fan 556 is installed.
- the first guide part 568a extends along the vertical direction to guide the air sucked by the second fan 556 from the top to the bottom.
- the second guide part 568b is provided at the lower end of the first guide part 568a to guide the air guided by the first guide part 568a to be discharged toward the front of the cabinet 510 through the lower side of the cabinet 510. It protrudes between the cabinet 510 and the floor.
- the second guide portion 568b extends forward.
- the air guided from the top to the bottom by the first guide part 568a is again guided to the front of the cabinet 510 by the second guide part 568b. And it is discharged to the front of the cabinet 510 through the discharge port of the support 570.
- the plurality of fins 555b of the second heat sink 555 extend in the vertical direction so that the air sucked by the second fan 556 flows from the top to the bottom. Spaced apart from each other. Accordingly, a vertical flow path is formed between the plurality of fins 555b. Air can be guided from top to bottom along this flow path. This structure can also be confirmed in FIG.
- the main plate 551 may be divided into a first portion 551a and a second portion 551b.
- the first portion 551a has an opening in which the second fan 556 is installed at a position facing the second fan 556.
- the second portion 551b is disposed at one side of the first portion 551a, and separates the shielding film from the first portion 551a so as to separate the first portion 551a from the shielding film disposed at the rear of the refrigerator 500. More protrudes toward you. Since the second part 551b protrudes more than the first part 551a, a flow path for intake of air may naturally be formed between the first part 551a and the shielding film. Therefore, the refrigerator 500 may not be provided with a stopper.
- FIG. 12 is a conceptual view illustrating another embodiment of a refrigerator 600 having a thermoelectric module.
- the heat dissipation cover 560 may further have at least one vent hole 669a, 669b, and 669b ′ around the opening where the second fan 656 is installed.
- a structure is suitable for a structure in which all sides of the refrigerator 600 are not shielded since there is a risk of resorption.
- the ventilation openings 669a are formed at the left and right sides of the opening, the hot air is lifted due to natural convection after being discharged through the ventilation openings, so there is little fear of re-suction. This is because the four sides of the refrigerator 600 are not shielded.
- vent holes 669b and 669b ' are formed at the left and right sides and the upper and lower sides of the opening, respectively.
- air can be discharged at a high flow rate. The higher the flow rate of the discharged air, the lower the chance of resorption.
- the refrigerator described above is not limited to the configuration and method of the above-described embodiments, but the embodiments may be configured by selectively combining all or some of the embodiments so that various modifications can be made.
- the present invention can be used in the industrial field related to the refrigerator.
