[0046] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0047] The present application discloses a storage device 10 .

[0048] Reference below Figure 1-Figure 7A storage device 10 according to an embodiment of the present application is described.

[0049] The storage device 10 may include, but is not limited to, a refrigerator, a freezer, or a vending machine with a temperature control function, etc., which is not limited here.

[0050] In some embodiments, Figure 1-Figure 7 As shown, the storage device 10 includes: a box body 100, a door body 300, and a heat exchange component.

[0051] The box body 100 is provided with a refrigeration chamber and a quick-freezing chamber 200; the door body 300 is installed at the front end of the box body 100.

[0052] like Figure 1-Figure 2 and Figure 6 As shown, the box body 100 can be used for heat preservation, the door body 300 can be used to seal the quick-freezing chamber 200, the quick-freezing chamber 200 can be used to quickly freeze food in a short time, and the refrigeration chamber can be used to install the refrigeration system 500, wherein the box body 100 can include a foam layer and other structural parts, and the foam layer can be used for heat insulation to reduce heat transfer.

[0053] The heat exchange assembly includes a loop heat pipe 400 and an evaporator 510 of a refrigeration system 500. The heat pipe evaporator 410 of the loop heat pipe 400 is used to exchange heat with the quick-freezing compartment 200. At least a portion of the evaporator 510 of the refrigeration system 500 is coupled to a heat pipe condenser 420 of the loop heat pipe 400 as a whole. The evaporator 510 of the refrigeration system 500 and the heat pipe condenser 420 of the loop heat pipe 400 are installed in the refrigeration bin.

[0054] like Figure 7 As shown, the loop heat pipe 400 may include a heat pipe evaporator 410, a heat pipe condenser 420, an air pipe 430 and a liquid pipe 440. The heat pipe evaporator 410 and the heat pipe condenser 420 may be connected through the air pipe 430 and the liquid pipe 440. A heat exchange medium may flow through the loop heat pipe 400. The inside of the loop heat pipe 400 may have a certain degree of vacuum. The heat exchange medium may be a fluid with phase change characteristics. The power may come from the pressure difference generated by the phase switching of the fluid.

[0055] like Figure 3-Figure 5 As shown, the refrigeration system 500 may include an evaporator 510, a condenser 520, a compressor 530 and a capillary tube 540. The evaporator 510, the condenser 520, the compressor 530 and the capillary tube 540 are connected end to end to form a loop for circulating refrigerant.

[0056] In actual implementation, Figure 1-Figure 7As shown, when the food is put into the quick-freezing chamber 200, the heat pipe evaporator 410 can quickly absorb the heat of the food, and the heat exchange medium inside the loop heat pipe 400 absorbs heat and evaporates to become a high-temperature gaseous heat exchange medium, thereby generating a pressure difference, driving the high-temperature gaseous heat exchange medium to flow to the heat pipe condenser 420, and the high-temperature gaseous heat exchange medium releases heat in the heat pipe condenser 420 to become a low-temperature liquid heat exchange medium, and then returns to the heat pipe evaporator 410. During this process, the refrigeration system 500 is in a working state, and the compressor 530 can compress the low-temperature and low-pressure gaseous refrigerant into a high-temperature and high-pressure gaseous refrigerant. The high-temperature and high-pressure gaseous refrigerant can be condensed and released through the condenser 520 to become a medium-temperature and high-pressure liquid refrigerant, and then the medium-temperature and high-pressure liquid refrigerant can pass through the capillary tube 540. It becomes a low-temperature and low-pressure liquid refrigerant; then the low-temperature and low-pressure liquid refrigerant passes through the evaporator 510 to absorb the heat emitted by the heat exchange medium in the heat pipe condenser 420 and becomes a low-temperature and low-pressure gaseous refrigerant. Finally, the low-temperature and low-pressure gaseous refrigerant returns to the compressor 530, and takes away the heat of the food through uninterrupted heat exchange between the heat pipe condenser 420 and the evaporator 510 of the refrigeration system 500, thereby achieving rapid cooling of the food. During the maintenance of the storage device 10, the heat pipe evaporator 410 of the loop heat pipe 400 can be removed from the quick-freezing chamber, and the heat pipe condenser 420 of the loop heat pipe 400 can be removed from the evaporator 510 of the refrigeration system 500, so that the entire loop heat pipe 400 can be brought out for maintenance.

[0057] The storage device 10 provided in the embodiment of the present application, through the arrangement of the above-mentioned loop heat pipe 400, cooperates with the structural design of coupling the condenser 520 of the loop heat pipe 400 and the evaporator 510 of the refrigeration system 500 as an integrated whole, realizes the efficient transfer of cold from the evaporator 510 of the refrigeration system 500 to the quick-freezing space, so that the heat pipe evaporator 410 can provide sufficient cold to support the quick-freezing function. At the same time, the loop heat pipe 400, as a single component, can be easily dismantled, repaired and replaced during the production and maintenance of the storage device 10, which is conducive to mass production.

[0058] In some embodiments, a thermally conductive filler may be disposed between the evaporator 510 of the refrigeration system 500 and the heat pipe condenser 420 of the loop heat pipe 400 .

[0059] The thermally conductive filler may include, but is not limited to, thermally conductive silicone, thermally conductive grease, or thermally conductive gel, etc. For example, in some embodiments, the thermally conductive filler is thermally conductive grease.

[0060] The storage device 10 provided in the embodiment of the present application can improve the thermal conductivity of the evaporator 510 of the refrigeration system 500 and the heat pipe condenser 420 of the loop heat pipe 400 through the setting of the above-mentioned thermally conductive filler, reduce the interface thermal resistance between the heat pipe condenser 420 and the evaporator 510 of the refrigeration system 500, and is more conducive to the formation of a heat conduction path.

[0061] In some embodiments, Figure 7 As shown, the heat pipe condenser 420 may include: a condensation plate.

[0062] A condensation channel is provided in the condensation plate, and the condensation channel is communicated with the channel of the heat pipe evaporator 410; the base plate of the evaporator 510 is attached to and connected with the condensation plate.

[0063] In this embodiment, if Figure 7 As shown, the heat pipe condenser 420 and the evaporator 510 are both plate structures. During the assembly process of the heat pipe condenser 420 and the evaporator 510, the condensation plate of the heat pipe condenser 420 and the substrate of the evaporator 510 can be punched or drilled, and the condensation plate and the substrate of the evaporator 510 can be fixedly connected by bolts, and a thermal conductive filler can be provided between the condensation plate of the heat pipe condenser 420 and the substrate of the evaporator 510, so as to achieve the coupling of the heat pipe condenser 420 and the evaporator 510 as one.

[0064] The evaporator 510 of the refrigeration system 500 may be an inflation evaporator or a 3D printed evaporator. For example, in some embodiments, the evaporator 510 of the refrigeration system 500 is an inflation evaporator.

[0065] The heat pipe condenser 420 may be an inflation condenser or a 3D printed condenser. For example, in some embodiments, the heat pipe condenser 420 is a 3D printed condenser.

[0066] In some embodiments, the heat pipe condenser 420 can be a plate structure, the evaporator 510 can be a tubular structure, the condensation plate of the heat pipe condenser 420 and the pipeline of the evaporator 510 can be connected by welding, and a thermal conductive filler can be arranged between the condensation plate of the heat pipe condenser 420 and the pipeline of the evaporator 510.

[0067] In other embodiments, the heat pipe condenser 420 may be a tubular structure, the evaporator 510 may be a plate structure, the pipes of the heat pipe condenser 420 may be connected to the substrate of the evaporator 510 by welding, and a thermal conductive filler may be provided between the pipes of the heat pipe condenser 420 and the substrate of the evaporator 510.

[0068] In some other embodiments, the heat pipe condenser 420 and the evaporator 510 are both tubular structures, the pipes of the heat pipe condenser 420 and the pipes of the evaporator 510 can be connected by welding, and thermal conductive fillers can be arranged between the pipes of the heat pipe condenser 420 and the pipes of the evaporator 510.

[0069] The storage device 10 provided in the embodiment of the present application realizes the coupling between the heat pipe condenser 420 and the evaporator 510 when both the heat pipe condenser 420 and the evaporator 510 are plate structures through the setting of the above-mentioned condensation plate. Compared with the plate-tube coupling and tube-tube coupling solutions, the coupling effect is better, the heat exchange efficiency is improved, and it is convenient to disassemble the loop heat pipe 400 as a single component for maintenance, thereby improving the maintainability of the entire storage device 10.

[0070] In some embodiments, Figure 3-Figure 5 As shown, the evaporator 510 may include a first evaporator 511 and a second evaporator 512 that are separately arranged, and the first evaporator 511 may be coupled to the heat pipe condenser 420 of the loop heat pipe 400; or, the evaporator 510 as a whole may be coupled to the heat pipe condenser 420 of the loop heat pipe 400.

[0071] The coupling method between the evaporator 510 and the heat pipe condenser 420 may include but is not limited to threaded connection, snap connection or bonding, etc. For example, in some embodiments, the coupling method between the evaporator 510 and the heat pipe condenser 420 is threaded connection.

[0072] In some embodiments, Figure 3 and Figure 7 As shown, the evaporator 510 as a whole can be coupled to the heat pipe condenser 420 of the loop heat pipe 400 .

[0073] In other embodiments, Figure 4 As shown, the evaporator 510 may include a first evaporator 511 and a second evaporator 512 that are separately arranged. The first evaporator 511 can be coupled to the heat pipe condenser 420 of the loop heat pipe 400, and the second evaporator 512 is used to provide cooling for the freezing compartment 800. The first evaporator 511 and the second evaporator 512 can be connected in series.

[0074] In some other embodiments, Figure 4 As shown, the evaporator 510 may include a first evaporator 511 and a second evaporator 512 which are separately arranged. The first evaporator 511 may be coupled to the heat pipe condenser 420 of the loop heat pipe 400, and the second evaporator 512 is used to provide cooling for the freezing compartment 800. The first evaporator 511 and the second evaporator 512 may be connected in parallel.

[0075] The storage device 10 provided in the embodiment of the present application provides a variety of refrigeration solutions according to actual needs through the structural design of the above-mentioned evaporator 510 being used for coupling in whole or in part, and the connection mode of series or parallel connection when the parts are coupled, and is more suitable for various usage scenarios such as general quick freezing and deep quick freezing.

[0076] In some embodiments, Figure 2 As shown, the heat pipe evaporator 410 of the loop heat pipe 400 can be attached to the bottom wall of the quick freezing chamber 200.

[0077] The connection method between the loop heat pipe 400 and the quick freezing chamber 200 may include but is not limited to bonding, threaded connection or riveting, etc. For example, in some embodiments, the connection method between the loop heat pipe 400 and the quick freezing chamber 200 is threaded connection.

[0078] In this embodiment, if Figure 2 As shown, the heat pipe evaporator 410 of the loop heat pipe 400 is attached to the bottom wall of the quick freezing chamber 200 , and the heat pipe evaporator 410 of the loop heat pipe 400 can be arranged outside the quick freezing chamber 200 .

[0079] In other embodiments, the heat pipe evaporator 410 of the loop heat pipe 400 is attached to the bottom wall of the quick-freezing chamber 200 , and the heat pipe evaporator 410 of the loop heat pipe 400 can be arranged in the quick-freezing chamber 200 .

[0080] The storage device 10 provided in the embodiment of the present application has a structural design in which the heat pipe evaporator 410 is attached to the bottom wall of the quick-freezing chamber 200, so that after the food is placed, the heat can be directly transferred to the heat pipe evaporator 410 through the bottom wall without the need for intermediate heat exchange through the air, thereby improving the efficiency of heat transfer.

[0081] In some embodiments, Figure 2 As shown, a heat conducting plate 600 may be provided on the bottom wall of the quick freezing chamber 200 , and the heat pipe evaporator 410 of the loop heat pipe 400 may be arranged outside the quick freezing chamber 200 and attached to the heat conducting plate 600 .

[0082] The heat conducting plate 600 may be made of metal, wherein the metal material may include but is not limited to stainless steel, aluminum alloy or copper alloy, etc. For example, in some embodiments, the heat conducting plate 600 is made of stainless steel.

[0083] In actual implementation, Figure 2 As shown, the food to be quick-frozen can be placed in the quick-freezing chamber 200. The surface of the food in contact with the air cools the food through convection heat exchange of the air. The contact surface between the bottom of the food and the heat conduction plate 600 receives the cold energy of the heat pipe evaporator 410, which promotes further rapid cooling of the food.

[0084] The storage device 10 provided in the embodiment of the present application, through the provision of the above-mentioned heat conducting plate 600, cooperates with the structural design of the heat pipe evaporator 410 being attached to the heat conducting plate 600, so that the cold energy of the heat pipe evaporator 410 can be directly transmitted to the bottom of the food through the heat conducting plate 600, and the high thermal conductivity of the heat conducting plate 600 can effectively achieve heat balance and energy transfer, thereby improving the heat transfer efficiency, thereby optimizing the working performance of the entire storage device 10.

[0085] In some embodiments, Figure 6 As shown, the heat pipe evaporator 410 of the loop heat pipe 400 may be located below the heat pipe condenser 420 of the loop heat pipe 400 in the gravity direction.

[0086] In this embodiment, since the heat exchange medium of the loop heat pipe 400 is a fluid with phase change characteristics, there is no need to drive components such as pumps, and the heat exchange medium can also circulate in the loop heat pipe 400. When the heat pipe evaporator 410 is located below the heat pipe condenser 420 in the direction of gravity, due to the increase in gravitational potential energy, the high-temperature gaseous heat exchange medium releases heat in the heat pipe condenser 420 and becomes a low-temperature liquid heat exchange medium. The low-temperature liquid heat exchange medium quickly falls back to the heat pipe evaporator 410 under the action of gravity. At the same time, based on the principle of thermal siphon, even if the height of the heat pipe evaporator 410 is lower than the heat pipe condenser 420, it does not affect the high-temperature gaseous heat exchange medium from quickly rising to the heat pipe condenser 420.

[0087] The storage device 10 provided in the embodiment of the present application accelerates the circulation speed of the heat exchange medium in the loop heat pipe 400 through the height design of the above-mentioned heat pipe evaporator 410 and the heat pipe condenser 420, prevents heat from accumulating in the loop heat pipe 400 for a long time, thereby maximizing the heat transfer efficiency and improving the quick freezing effect.

[0088] In some embodiments, Figure 1-Figure 2 and Figure 6 As shown, the heat pipe condenser 420 of the loop heat pipe 400 may be arranged at the back of the quick freezing chamber 200 .

[0089] It is understandable that if the heat pipe condenser of the loop heat pipe is not arranged at the back of the quick-freezing chamber, in other words, the heat pipe condenser of the loop heat pipe is arranged at the side of the quick-freezing chamber, then sufficient heat dissipation air duct needs to flow between the outer shell of the storage device and the inner liner of the box body, resulting in an increase in the width of the entire storage device, which is not conducive to the spatial layout. In addition, when the storage device is arranged in the space, the two sides are usually in an open space, and the probability of possible collision is greatly increased, affecting the reliability of the heat pipe. At the same time, in terms of appearance, arranging the heat pipe condenser of the loop heat pipe on the side also affects the aesthetics.

[0090] When the heat pipe condenser 420 of the loop heat pipe 400 is arranged at the back of the quick-freezing chamber 200, the heat dissipation duct is hidden at the back of the storage device 10, and only the depth of the storage device 10 is increased. Compared with affecting the width of the storage device 10, it is more conducive to spatial layout. Moreover, the back of the storage device 10 is usually in a semi-enclosed space when the space is arranged, and the probability of possible collision is greatly reduced, thereby improving the reliability of the loop heat pipe 400, and also making the overall appearance of the storage device 10 more beautiful.

[0091] In some embodiments, Figure 6 As shown, the quick freezing chamber 200 has an air outlet 210 and an air return outlet 220 , and the box body 100 defines an air supply duct and an air return duct. The air supply duct is connected to the air outlet 210 , and the air return duct is connected to the air return outlet 220 .

[0092] In this embodiment, if Figure 6 As shown, the air outlet 210 can be arranged below the return air outlet 220, and the air outlet 210 and the return air outlet 220 can be arranged diagonally. When the food is placed in the quick-freezing chamber 200, the heat pipe evaporator 410 can absorb the heat of the food, promote the rapid cooling and freezing of the food, and at the same time, the air supply duct sends the airflow with the cold amount of the refrigeration system 500 into the quick-freezing chamber 200 through the air outlet 210 of the quick-freezing chamber 200. The cold air directly exchanges heat with the food, and the hot air after absorbing the heat enters the return air duct through the return air outlet 220 of the quick-freezing chamber 200, and finally leaves the cabinet liner 100.

[0093] The storage device 10 provided in the embodiment of the present application, through the arrangement of the above-mentioned air outlet 210, return air outlet 220, supply air duct and return air duct, realizes that the loop heat pipe 400 is combined with the air cooling unit to provide cold capacity for the quick-freezing chamber 200, improves the air circulation effect in the quick-freezing chamber 200, increases the convection effect between the surface of the food and the air, shortens the time required for quick-freezing of the food to the greatest extent, and prolongs the storage time of the food.

[0094] In some embodiments, Figure 6 As shown, the evaporator 510 of the refrigeration system 500 may be arranged on a side of the heat pipe condenser 420 of the loop heat pipe 400 that is away from the quick freezing compartment 200 .

[0095] In actual implementation, Figure 6As shown, when food is put into the quick-freezing chamber 200, the heat pipe evaporator 410 can absorb the heat of the food, promote the rapid cooling and freezing of the food, and the external airflow can enter the air supply duct. Most of the airflow can first pass through the evaporator 510 of the refrigeration system 500 to become low-temperature airflow, and the low-temperature airflow can then pass through the heat pipe condenser 420 closer to the quick-freezing chamber 200. Then, the airflow with the cold amount of the refrigeration system 500 can be sent into the quick-freezing chamber 200 through the air outlet 210 of the quick-freezing chamber 200. The cold air directly exchanges heat with the food, and the hot air after absorbing the heat enters the return air duct through the return air outlet 220 of the quick-freezing chamber 200, and finally leaves the cabinet liner 100.

[0096] The storage device 10 provided in the embodiment of the present application, through the spatial position design of the evaporator 510 of the refrigeration system 500 and the heat pipe condenser 420, allows the airflow entering the air supply duct to pass through the evaporator 510 of the refrigeration system 500 as much as possible, thereby optimizing the cooling effect of air-cooled heat dissipation and avoiding staggered pipe layout, making the overall structure more concise.

[0097] In some embodiments, Figure 6 As shown, the box body 100 may also be provided with a refrigerating compartment 700 and a freezing compartment 800, the quick-freezing compartment 200, the refrigerating compartment 700 and the freezing compartment 800 may be separately arranged, the quick-freezing compartment 200 may be arranged between the refrigerating compartment 700 and the freezing compartment 800, and the box body 100 may define an air supply duct and an air return duct, and both the air supply duct and the air return duct may be connected to the refrigerating compartment 700 and the freezing compartment 800.

[0098] In this embodiment, if Figure 6 As shown, based on the air supply duct supplying air to the refrigerating compartment 700, the quick freezing compartment 200 and the freezing compartment 800 from bottom to top, there is inevitably a loss of cold energy during the air supply process. A part of the air flow can enter the freezing compartment 800 located at the bottom, another part of the air flow can enter the quick freezing compartment 200 located in the middle, and another part of the air flow can enter the refrigerating compartment 700 located at the top. The temperature of the air flow entering the freezing compartment 800 is lower than the temperature of the air flow entering the quick freezing compartment 200, and the temperature of the air flow entering the quick freezing compartment 200 is lower than the temperature of the air flow entering the refrigerating compartment 700, so that the temperature of the air flow entering the freezing compartment 800 is sufficient to meet the demand of low-temperature freezing of the freezing compartment 800, the temperature of the air flow entering the quick freezing compartment 200 combined with the cold energy provided by the heat pipe evaporator 410 is sufficient to meet the demand of ultra-low temperature quick freezing of the quick freezing compartment 200, and the temperature of the air flow entering the refrigerating compartment 700 is sufficient to meet the demand of relatively low-temperature refrigeration of the refrigerating compartment 700.

[0099] The storage device 10 provided in the embodiment of the present application, through the arrangement of the above-mentioned refrigerating compartment 700 and freezing compartment 800, cooperates with the spatial position design of the quick-freezing compartment 200, the refrigerating compartment 700 and the freezing compartment 800, so that the cooling capacity of the refrigeration system 500 is reasonably distributed to the quick-freezing compartment 200, the refrigerating compartment 700 and the freezing compartment 800 to meet the different temperature requirements of different compartments, thereby effectively improving the stability and performance of the storage device 10.

[0100] In some embodiments, Figure 6 As shown, the door body 300 may include a first door body 310, a second door body 320 and a third door body 330 which are separately arranged. The first door body 310, the second door body 320 and the third door body 330 may respectively block the refrigerating compartment 700, the quick freezing compartment 200 and the freezing compartment 800 in sequence.

[0101] The first door body 310 may be a side-opening door, a top-opening door, or a double-opening door, etc. For example, in some embodiments, the first door body 310 may be a double-opening door.

[0102] The second door body 320 may be a side-opening door, a top-opening door, a double-opening door, etc. For example, in some embodiments, the second door body 320 may be a side-opening door.

[0103] The third door body 330 may be a side-opening door, a top-opening door, or a double-opening door, etc. For example, in some embodiments, the third door body 330 may be a side-opening door.

[0104] The storage device 10 provided in the embodiment of the present application realizes independent opening and closing of the doors of the refrigerating compartment 700, the quick freezing compartment 200 and the freezing compartment 800 through the arrangement of the above-mentioned first door body 310, the second door body 320 and the third door body 330, thereby preventing the refrigerating compartment 700, the quick freezing compartment 200 and the freezing compartment 800 from interfering with each other, enhancing the sealing of the refrigerating compartment 700, the quick freezing compartment 200 and the freezing compartment 800, and making the temperature control of each compartment of the storage device 10 more precise.

[0105] The present application also provides a quick freezing system.

[0106] In some embodiments, Figure 1-Figure 2 As shown, the quick freezing system includes: a heat exchange component and a quick freezing chamber 200.

[0107] The heat exchange assembly includes a loop heat pipe 400 and an evaporator 510 of a refrigeration system 500 . At least a portion of the evaporator 510 of the refrigeration system 500 is coupled to a heat pipe condenser 410 of the loop heat pipe 400 . The heat pipe evaporator 410 of the loop heat pipe 400 is installed in the quick freezing chamber 200 .

[0108] like Figure 1-Figure 5As shown, the loop heat pipe 400 may include a heat pipe evaporator 410 and a heat pipe condenser 420. A heat exchange medium may flow through the loop heat pipe 400. The interior of the loop heat pipe 400 may have a certain degree of vacuum. The heat exchange medium may be a fluid with phase change characteristics. The power may come from the pressure difference generated by the phase switching of the fluid.

[0109] In actual implementation, Figure 1-Figure 6 As shown, when the food is put into the quick-freezing chamber 200, the heat pipe evaporator 410 can quickly absorb the heat of the food, and the heat exchange medium inside the loop heat pipe 400 absorbs heat and evaporates to become a high-temperature gaseous heat exchange medium, thereby generating a pressure difference, driving the high-temperature gaseous heat exchange medium to flow to the heat pipe condenser 420, and the high-temperature gaseous heat exchange medium releases heat in the heat pipe condenser 420 to become a low-temperature liquid heat exchange medium, and the evaporator 510 of the refrigeration system 500 can absorb the heat released by the high-temperature gaseous heat exchange medium, and the low-temperature liquid heat exchange medium can return to the heat pipe evaporator 410, and the heat of the food is taken away by the uninterrupted heat exchange between the heat pipe condenser 420 and the evaporator 510 of the refrigeration system 500, thereby achieving rapid cooling of the food.

[0110] The quick-freezing chamber 200 provided in the embodiment of the present application, through the arrangement of the above-mentioned loop heat pipe 400, cooperates with the structural design of the heat exchange between the condenser 520 of the loop heat pipe 400 and the evaporator 510 of the refrigeration system 500, reduces the temperature difference between the quick-freezing space and the heat pipe evaporator 410, and realizes the rapid transfer of the heat of the food in the quick-freezing chamber 200 to the heat pipe evaporator 410, thereby realizing the quick freezing function. At the same time, the loop heat pipe 400, as a single component, can be easily dismantled, repaired and replaced during the production and maintenance process of the storage device 10, which is conducive to mass production.

[0111] In some embodiments, Figure 2 As shown, the heat pipe evaporator 410 of the loop heat pipe 400 can be attached to the bottom wall of the quick freezing chamber 200.

[0112] The connection method between the loop heat pipe 400 and the quick freezing chamber 200 may include but is not limited to bonding, threaded connection or riveting, etc. For example, in some embodiments, the connection method between the loop heat pipe 400 and the quick freezing chamber 200 is threaded connection.

[0113] In this embodiment, if Figure 2 As shown, the heat pipe evaporator 410 of the loop heat pipe 400 is attached to the bottom wall of the quick freezing chamber 200 , and the heat pipe evaporator 410 of the loop heat pipe 400 can be arranged outside the quick freezing chamber 200 .

[0114] In other embodiments, the heat pipe evaporator 410 of the loop heat pipe 400 is attached to the bottom wall of the quick-freezing chamber 200 , and the heat pipe evaporator 410 of the loop heat pipe 400 can be arranged in the quick-freezing chamber 200 .

[0115] The quick-freezing system provided in the embodiment of the present application is designed so that the heat pipe evaporator 410 is attached to the bottom wall of the quick-freezing chamber 200, so that after the food is placed, the heat can be directly transferred to the heat pipe evaporator 410 through the bottom wall without the need for intermediate heat exchange through the air, thereby improving the efficiency of heat transfer.

[0116] In some embodiments, Figure 2 As shown, a heat conducting plate 600 may be provided on the bottom wall of the quick freezing chamber 200 , and the heat pipe evaporator 410 of the loop heat pipe 400 may be arranged outside the quick freezing chamber 200 and attached to the heat conducting plate 600 .

[0117] The heat conducting plate 600 may be made of metal, wherein the metal material may include but is not limited to stainless steel, aluminum alloy or copper alloy, etc. For example, in some embodiments, the heat conducting plate 600 is made of stainless steel.

[0118] In actual implementation, Figure 2 As shown, the food to be quick-frozen can be placed in the quick-freezing chamber 200. The surface of the food in contact with the air cools the food through convection heat exchange of the air. The contact surface between the bottom of the food and the heat conduction plate 600 receives the cold energy of the heat pipe evaporator 410, which promotes further rapid cooling of the food.

[0119] The quick freezing system provided in the embodiment of the present application, through the setting of the above-mentioned heat conducting plate 600, cooperates with the structural design of the heat pipe evaporator 410 being attached to the heat conducting plate 600, so that the cold energy of the heat pipe evaporator 410 can be directly transmitted to the bottom of the food through the heat conducting plate 600, and the high thermal conductivity of the heat conducting plate 600 can effectively achieve heat balance and energy transfer, thereby improving the heat transfer efficiency, thereby optimizing the working performance of the entire storage device 10.

[0120] In some embodiments, Figure 6 As shown, the heat pipe evaporator 410 of the loop heat pipe 400 may be located below the heat pipe condenser 420 of the loop heat pipe 400 in the gravity direction.

[0121] In this embodiment, since the heat exchange medium of the loop heat pipe 400 is a fluid with phase change characteristics, there is no need to drive components such as pumps, and the heat exchange medium can also circulate in the loop heat pipe 400. When the heat pipe evaporator 410 is located below the heat pipe condenser 420 in the direction of gravity, due to the increase in gravitational potential energy, the high-temperature gaseous heat exchange medium releases heat in the heat pipe condenser 420 and becomes a low-temperature liquid heat exchange medium. The low-temperature liquid heat exchange medium quickly falls back to the heat pipe evaporator 410 under the action of gravity. At the same time, based on the principle of thermal siphon, even if the height of the heat pipe evaporator 410 is lower than the heat pipe condenser 420, it does not affect the high-temperature gaseous heat exchange medium from quickly rising to the heat pipe condenser 420.

[0122] The quick freezing system provided in the embodiment of the present application accelerates the circulation speed of the heat exchange medium in the loop heat pipe 400 through the high-level design of the above-mentioned heat pipe evaporator 410 and the heat pipe condenser 420, prevents heat from accumulating in the loop heat pipe 400 for a long time, thereby maximizing the heat transfer efficiency and improving the quick freezing effect.

[0123] In some embodiments, Figure 1-Figure 2 and Figure 6 As shown, the heat pipe condenser 420 of the loop heat pipe 400 may be arranged at the back of the quick freezing chamber 200 .

[0124] It is understandable that if the heat pipe condenser of the loop heat pipe is not arranged at the back of the quick-freezing chamber, in other words, the heat pipe condenser of the loop heat pipe is arranged at the side of the quick-freezing chamber, then sufficient heat dissipation air duct needs to flow between the outer shell of the storage device and the inner liner of the box body, resulting in an increase in the width of the entire storage device, which is not conducive to the spatial layout. In addition, when the storage device is arranged in the space, the two sides are usually in an open space, and the probability of possible collision is greatly increased, affecting the reliability of the heat pipe. At the same time, in terms of appearance, arranging the heat pipe condenser of the loop heat pipe on the side also affects the aesthetics.

[0125] When the heat pipe condenser 420 of the loop heat pipe 400 is arranged at the back of the quick-freezing chamber 200, the heat dissipation duct is hidden at the back of the storage device 10, and only the depth of the storage device 10 is increased. Compared with affecting the width of the storage device 10, it is more conducive to spatial layout. Moreover, the back of the storage device 10 is usually in a semi-enclosed space when the space is arranged, and the probability of possible collision is greatly reduced, thereby improving the reliability of the loop heat pipe 400, and also making the overall appearance of the storage device 10 more beautiful.
