Description

Technical Field

[0001] This invention belongs to the technical field of refrigeration and heating equipment, specifically, it relates to a refrigeration and heating cabinet with both refrigeration and heating functions and its usage method. Background Technology

[0002] A refrigerated display case, as a structure distinct from traditional refrigerated display cases, is a more comprehensive multi-functional display case that can provide both refrigeration and heating functions. It is mainly used in convenience stores, restaurants, and other places that require refrigeration and heat preservation of food. Compared with the single-function refrigerated and heating display cases in existing technologies, it can achieve two functions in one unit, with one unit completing the work of two units. It occupies less space, has more functions, and is more convenient to use.

[0003] Common refrigerators and warmer cabinets typically use vertical or horizontal partitions to separate cold and hot zones for categorized cooling and insulation. Most employ independent heating and cooling zones for the cold and hot areas. For example, Chinese patent CN222187532U proposes a refrigerator and warmer cabinet with simultaneous cooling and heating functions. This cabinet primarily provides the cold zone space through a refrigeration unit and creates the hot zone space by installing a heating unit outside the cold zone. While it achieves both cooling and heating functions, these two functions are difficult to maintain simultaneously. Furthermore, if cold storage is performed first, followed by heating, the frost that has condensed inside may dissipate due to the sudden temperature increase. The formation of water droplets affects subsequent storage performance. Furthermore, Chinese patent CN119915067A describes a hot and cold air cabinet with a hot and cold air duct switching mechanism. This method uses hot and cold air switching to control the range of the cold and hot zones, achieving simultaneous cooling and heating. However, the limited thermal conductivity of gas as a medium results in a slow heating rate in the hot zone. Due to limitations in duct layout and heat convection conditions, the synchronicity of cooling in the cold zone and heating in the hot zone is insufficient, making it difficult to guarantee simultaneous heating and cooling. Moreover, using hot air as a supplementary heating function is more suitable than using hot air as the primary heating method, which has poor heating effect and can easily affect the cold zone.

[0004] Therefore, existing technologies need further improvement and enhancement. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a refrigerator and a method of using a refrigerator and a heater that have both cooling and heating functions.

[0006] To achieve the above objectives, the technical solution of the present invention is: a refrigerator / heater cabinet that simultaneously has cooling and heating functions, comprising: a cabinet body: serving as an outer shell structure, internally divided into a cooling zone and a heating zone; a circulation component: disposed between the cooling zone and the heating zone, including a circulation pipeline and a heat-conducting medium disposed within the circulation pipeline; and a heat transfer component: including a heat-absorbing part, a heat-releasing part, and a heat regulation control part, respectively disposed in the cooling zone and the heating zone, with the heat regulation control part disposed at the connection between the cooling zone, the circulation component, and the heating zone.

[0007] In a preferred embodiment of this application, a heat exchange zone is provided between the cooling zone and the heating zone, and a heat regulation control device is provided at the connection point of the three zones.

[0008] In a preferred embodiment of this application, a heat-conducting plate is provided inside the inner wall of the cooling zone and the heating zone, and the heat-absorbing part and the heat-releasing part are respectively connected to the heat-conducting plate.

[0009] In a preferred embodiment of this application, the circulation pipeline includes a first medium tank, a second medium tank, and a connecting pipe connecting the two. The first medium tank and the second medium tank are respectively disposed on the outer walls of the cooling zone and the heating zone.

[0010] In a preferred embodiment of this application, the connecting pipe is divided into a conveying section and a return section, which are arranged on the same plane, and a pump body is provided on the surface of both the conveying section and the return section.

[0011] In a preferred embodiment of this application, the heat regulation control uses a thermoelectric refrigeration module based on the Peltier effect.

[0012] In a preferred embodiment of this application, the circulation assembly further includes a heat insulation plate with an opening for accommodating the circulation pipeline, and the heat insulation plate is positioned in the middle of the circulation pipeline.

[0013] In a preferred embodiment of this application, the circulation assembly further includes a protective shell, a movable hinge portion disposed on the side wall of the protective shell, and a temperature sensing element disposed inside the protective shell.

[0014] In a preferred embodiment of this application, the thermally conductive medium includes a phase change material medium and a thermally conductive liquid, wherein the phase change material medium is integrated into a phase change material microcapsule and is carried and flowed by the thermally conductive liquid.

[0015] This application also provides a method for using a refrigerator / heater cabinet that simultaneously has cooling and heating functions, based on the aforementioned refrigerator / heater cabinet, including: S1, the cooling zone is in operation and enters the cooling state; S2. The heat regulation control at the connection of the refrigeration zone, together with the heat absorption part, actively absorbs the heat in the refrigeration zone to the heat transfer medium of the circulation pipeline. S3. The circulation component drives the heat transfer medium to flow to the heating zone along a preset direction. S4. The heat regulation control at the connection of the heating zone, together with the heat release part, releases the heat carried by the heat transfer medium to the heating zone, thereby raising the temperature of the heating zone. S5. The heat transfer medium flows in a closed loop within the circulation pipeline, achieving simultaneous cooling of the cooling zone and heating of the heating zone while the cooling zone continues to cool down.

[0016] By adopting the above technical solutions, the corn kernel storage box and corn kernel harvester provided by the present invention have the following beneficial effects compared with the prior art.

[0017] 1. This application provides a refrigerator / heater cabinet that simultaneously has cooling and heating functions. By dividing the cabinet into cooling and heating zones, a basic hot and cold zone environment is formed, allowing for the storage of products with different needs. Through the cooperation of the heat-conducting medium in the circulation pipeline and the heat regulation control, the heat absorption at the heat absorption section is actively regulated, absorbing heat from the cooling zone into the circulation pipeline and transferring it to the heat release section and heat regulation control in the heating zone, rapidly increasing the temperature in the heating zone. This achieves different working environments for the cooling and heating zones. Furthermore, the closed-loop flow of the heat-conducting medium in the circulation component improves heat conduction and heat transfer performance while realizing resource recycling.

[0018] 2. As a preferred embodiment of this application, by assembling a heat exchange zone between the cooling zone and the heating zone, heat loss is avoided while providing space for the circulation components. The setting of the heat conduction plate facilitates the flow of heat in the cooling zone and the heating zone to the heat absorption part and the heat conduction part, thereby accelerating heat transfer. In addition, the pump body is used to realize the active delivery of the circulation medium, and the heat conduction effect can be changed by adjusting the flow rate of the circulation medium.

[0019] 3. As a preferred embodiment of this application, a thermoelectric cooling module is used as a heat regulation control unit. This heat regulation control unit is based on the Peltier effect and can achieve the function of absorbing heat on one side and releasing heat on the other side. This satisfies the requirement that the heat-absorbing end is close to the heat-absorbing part of the cooling zone, so as to absorb heat in the cooling zone, reduce its temperature, and quickly transfer heat to the circulation pipeline. In the other part of the heating zone, the heat-releasing side is close to the heat-releasing part of the heating zone. On the one hand, the heat in the circulation pipeline is actively drawn into the heating zone, and on the other hand, the heating of the heating zone can be controlled to achieve adjustable temperature. Furthermore, the setting of the heat insulation plate can reduce the mutual influence between the heating zone and the cooling zone to a certain extent, avoid the interference of their temperatures, and ensure the synchronous operation of the cooling and heating functions.

[0020] 4. As a preferred embodiment of this application, this application defines the heat-conducting medium, not only using a heat-conducting liquid as the medium, but also, compared with traditional gas, the heat-conducting liquid has a better heat transfer effect and higher efficiency. Furthermore, by adding a phase change material medium to the heat-conducting liquid, the heat-conducting liquid's already high heat conductivity is further enhanced by the phase change material medium to improve its heat release and heat storage capabilities, thereby improving heat transfer efficiency.

[0023] It should be noted that these accompanying drawings and textual descriptions are not intended to limit the scope of the invention in any way, but rather to illustrate the concept of the invention to those skilled in the art by referring to specific embodiments. Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0025] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0026] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0027] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0028] like Figures 1 to 6 As shown, the present invention provides a technical solution: a refrigerator / heater cabinet with both cooling and heating functions, comprising: a cabinet 1: serving as an outer shell structure, internally divided into a cooling zone 11 and a heating zone 12; a circulation component 2: disposed between the cooling zone 11 and the heating zone 12, including a circulation pipe 21 and a heat-conducting medium 22 disposed within the circulation pipe 21; and a heat transfer component 3: including a heat-absorbing part 31, a heat-releasing part 32, and a heat regulation control 33, respectively disposed in the cooling zone 11 and the heating zone 12, with the heat regulation control 33 disposed at the connection between the cooling zone 11, the circulation component 2, and the heating zone 12.

[0029] In one optional embodiment, the housing 1 can be a cuboid structure, with the cooling zone 11 and the heating zone 12 respectively located on both sides of the housing 1, forming a left-right arrangement. A circulation component 2 is provided between the two, and the circulation pipe 21 serves as the flow and placement path for the heat transfer medium 22. Compared with the method of directly using a hot air blower for heat transfer, this application improves the efficiency of heat transfer through the heat transfer medium 22 and realizes the recycling of resources through the circulation pipe 21 that allows the heat transfer medium 22 to circulate, thereby reducing the cost of heat transfer to a certain extent.

[0030] Of course, the overall cabinet structure 1 of the refrigerator can also adopt a vertical cabinet structure. Similarly, the distribution of the internal circulation components 2, the cooling zone 11 and the heating zone 12 should also be changed to a vertical arrangement. Other structures and heat conduction methods are the same as the implementation method with horizontal distribution on both sides. This application will not elaborate on them here, but will take the rectangular cabinet 1 horizontally arranged and the cooling zone 11 and the heating zone 12 divided into two sides as an example.

[0031] In a preferred embodiment of this application, a heat exchange zone 13 is provided between the cooling zone 11 and the heating zone 12, and a heat regulation control device 33 is provided at the connection point of the three zones.

[0032] It should be noted that cooling zones 11 and 12 can still be equipped with cooling structures such as compressors and heating structures such as electric heating plates to ensure the basic functions of cooling zones 11 and 12. Furthermore, the heat control control unit 33, such as... Figure 1 and Figure 2 As shown, the heat exchange zone 13 is also located inside the housing 1. The housing 1 is divided into three parts: the left side serves as the cold zone storage box for the cooling zone 11, the right side serves as the hot zone storage box for the heating zone 12, and the space left in the middle of the housing 1 serves as the heat exchange zone 13. The circulation component 2 is set in it to ensure the transfer and circulation of heat. The heat regulation control 33 is set at the connection between the cooling zone 11 and the heating zone 12 and the heat exchange zone 13 to make real-time adjustments during heat absorption and release, so as to achieve efficient cooling and heating functions.

[0033] The inner walls of the refrigeration zone 11 and the heating zone 12 are equipped with heat-conducting plates 14. The heat-absorbing part 31 and the heat-releasing part 32 are respectively connected to the heat-conducting plates 14. As can be seen from the figure, the inner walls of the refrigeration zone 11 and the heating zone 12 are surrounded by the heat-conducting plate 14 structure. While storing food or other items stored in the refrigeration zone 11 and the heating zone 12, they can also be connected to the heat-absorbing part 31 and the heat-releasing part 32 to improve the heat transfer efficiency between the heat-absorbing part 31 and the heat-releasing part 32, thereby accelerating heat exchange.

[0034] Specifically, for the heat regulation control unit 33, a thermoelectric cooling module based on the Peltier effect can be used. The Peltier effect refers to the phenomenon that when current flows through a circuit composed of different conductors, in addition to generating irreversible Joule heating, heat absorption and release phenomena occur at the junctions of different conductors depending on the direction of the current. Since charge carriers are at different energy levels in different materials, when they move from a higher energy level to a lower energy level, they release excess energy; conversely, when they move from a lower energy level to a higher energy level, they absorb energy from the outside. Energy is absorbed or released in the form of heat at the interface between the two materials. This effect is reversible; if the direction of the current is reversed, heat absorption is transformed into heat release. This thermoelectric cooling module is based on the Peltier effect and is designed to achieve heat absorption and heat release functions on both sides. In the cooling zone 11, the heat-absorbing end faces the cooling zone 11, and in the heat-releasing zone, the heat-releasing end faces the heat-releasing zone. Through multiple thermoelectric cooling modules, efficient cooling and heating are achieved at both locations, thereby improving the efficiency of heat transfer.

[0035] It is understood that the thermoelectric cooling module includes a thermocouple unit formed by alternating sets of P-type semiconductor elements and N-type semiconductor elements. A first ceramic substrate and a second ceramic substrate are respectively disposed on both sides of the thermocouple unit. The first ceramic substrate forms the heat-absorbing side interface, and the second ceramic substrate forms the heat-releasing side interface. When the thermoelectric cooling module is energized, the current flows in the thermocouple unit, causing the heat-absorbing side interface to produce a heat-absorbing effect, while the heat-releasing side interface produces a heat-releasing effect, thereby realizing the directional transport of heat.

[0036] In other words, under the action of the thermoelectric cooling module, at the cooling zone 11, the first ceramic substrate can be connected to the heat-absorbing part 31. The heat-absorbing part 31 and the heat-releasing part 32 can adopt a plate-like structure. One side of the two can be embedded in the cooling zone 11 and the heating zone 12 to facilitate connection with the internal heat-conducting plate 14 and improve the heat conduction effect. The other side can be connected to the thermoelectric cooling module set at the connection point to ensure the heat absorption and heat release effect. Taking the heat-absorbing part 31 as an example, it can adopt a plate-like structure made of aluminum or aluminum alloy, and the contact surface between it and the heat regulation control 33 is provided with a thermal interface material. The thermal interface material can be thermal grease or thermal phase change sheet to reduce the contact thermal resistance.

[0037] Furthermore, the circulation assembly 2 also includes a heat insulation plate 23, which has an opening for housing the circulation pipe 21. The heat insulation plate 23 is positioned in the middle of the circulation pipe 21. By installing the heat insulation plate 23 between the cooling zone and the heating zone, and only having an opening on the heat insulation plate 23 for the circulation pipe 21 to pass through, no other heat transfer channels are formed between the cooling zone and the heating zone except for the circulation pipe 21. This avoids disordered heat conduction and heat crosstalk between the cold and hot zones, ensuring that heat is transferred only along the path defined by the heat absorption part 31, the heat regulation control 33, and the circulation pipe 21, thereby improving the controllability of heat transport and the system energy efficiency.

[0038] from Figure 2 and Figure 4 As can be seen, the insulation plate 23 is set in the middle area of ​​the entire heat exchange zone 13, dividing the circulation pipe 21 into left and right parts. The opening structure of the insulation plate 23 is designed to allow the circulation pipe 21 to pass through smoothly, ensuring the normal circulation of the medium in the circulation pipe 21, and preventing cross-flow of temperature between the cooling zone 11 and the heating zone 12, ensuring the uniqueness of the heat transfer path and the uniqueness of the heat circulation along the circulation pipe 21.

[0039] Furthermore, the circulation pipeline 21 includes a first medium tank 211, a second medium tank 212, and a connecting pipe 213 connecting the two. The first medium tank 211 and the second medium tank 212 are respectively disposed on the outer walls of the cooling zone 11 and the heating zone 12. The connecting pipe 213 is divided into a conveying section 2131 and a return section 2132, which are coplanar. Pump bodies are disposed on the surfaces of both the conveying section 2131 and the return section 2132.

[0040] Specifically, the connecting pipe 213, as an O-type circulation structure, ensures that the medium can flow from the first medium tank 211 to the second medium tank 212 and back from the second medium tank 212 to the first medium tank 211. To ensure the irreversibility of the flow direction, pump bodies and one-way valve structures can be installed at both the conveying section 2131 and the return section 2132. The first medium tank 211 is located near the refrigeration zone 11, with one end connected to the circulation pipe 21 and the other end connected to the heat control control 33 at the refrigeration zone 11 to ensure the heat at the refrigeration zone 11. Under the action of the heat regulator 33, the medium flows into the first medium tank 211, and under the action of the circulation pipe 21, the medium flows into the second medium tank 212, which is close to the heating zone 12. The second medium tank 212 is located close to the heating zone 12. One end of it is connected to the circulation pipe 21 to receive the medium from the first medium tank 211, and the other end is connected to the heat regulator 33 located there. It can absorb the heat in the second medium tank 212 and release it into the heating zone 12, thereby increasing the temperature of the heating zone 12 and realizing the transfer of heat.

[0041] For example, it can be adopted Figure 2 and Figure 4 The structure shown has the conveying section 2131 located at the bottom and the return section 2132 located at the top. Multiple conveying sections 2131 and return sections 2132 can be set up as needed. Of course, the positions of the two sections can also be set in different locations as needed to improve adaptability.

[0042] Specifically, such as Figure 5 As shown, for the heat exchange path of the circulation component 2 within the heat exchange zone 13, and within the cooling zone 11 where items are stored, heat will naturally flow towards the heat absorption part 31 under the action of the heat conduction plate 14. Subsequently, under the active control of the heat regulation control 33, the heat absorption end absorbs heat from the heat absorption part 31 and transfers the heat to the first medium tank 211 through the heat release end, achieving continuous heat absorption and cooling of the heating zone 12. The medium in the first medium tank 211 carries heat and continues to flow into the second medium tank 212 via the conveying section 2131, causing the temperature inside the second medium tank 212 to gradually rise. At this time, the temperature inside the second medium tank 212... The heat absorption end of the heat regulation control 33 connected to the outer wall absorbs heat from the second medium tank 212 and is connected to the heat release section 32 through the heat release end, transferring the heat to the heating zone 12 connected to the heat release section 32. This continuously increases the temperature in the heating zone 12, ensuring the internal storage effect. Subsequently, the medium in the second medium tank 212 returns to the first medium tank 211 along the return section 2132. Since the heat has been released into the heating zone 12, the temperature in the first medium tank 211 decreases again, entering the next cycle, realizing continuous and rapid heat transfer, thereby achieving the functions of heating and cooling.

[0043] It is understandable that by actively regulating the heat control component 33, rapid heat transfer is achieved. Compared with the existing technology, which directly regulates the temperature through heating and cooling components, the solution of this application does not require additional heating and cooling components. Instead of dissipating heat at the cooling end and heating independently at the heating end, the heat generated in the cooling zone 11 is actively transferred to the heating zone 12 through the heat transfer component 3 and the circulating medium, thereby achieving effective utilization of heat. Furthermore, the circulation pipeline 21 enables the recycling of resources and heat, improving energy efficiency.

[0044] Optionally, the heat-conducting medium 22 includes a phase change material medium and a heat-conducting liquid. The phase change material medium is integrated into a phase change material microcapsule and is carried and flowed by the heat-conducting liquid. The heat-conducting liquid can be... The heat-conducting liquid acts as a circulating carrier, transporting heat from the cooling zone 11 to the heating zone 12. Furthermore, by incorporating microcapsule structures made of phase change materials, the latent heat effect of the phase change materials is utilized to absorb or release a large amount of heat when the temperature reaches the phase change temperature, thereby improving the heat conduction effect.

[0045] Specifically, such as Figure 5 As shown, the microcapsules can be made of phase change materials, such as paraffin, fatty acids, or PEG, and are encapsulated by a highly thermally conductive but sealed film (such as polyurethane, epoxy resin, or silicone) to prevent leakage of the phase change material. During the cycle, in the cooling zone 11, the temperature of the medium in the first medium tank 211 gradually increases due to the action of the heat regulation control 33. The phase change material absorbs heat. During the phase change process, the PCM temperature does not change much, but it absorbs a large amount of latent heat, and the overall temperature of the medium rises slowly, ensuring that the temperature in the cooling zone 11 is stably transported. Subsequently, the thermally conductive medium 2 2. The medium continues to be transported along the conveying section 2131 of the circulation pipeline 21 to the second medium tank 212. During the transportation process, the temperature does not change much, and the microcapsule is in a state of storing heat. When the heat-conducting medium 22 enters the second medium tank 212, under the action of the heat regulation control 33, the temperature in the second medium continues to release heat towards the heat-releasing part 32. At this time, since the temperature of the heat-conducting medium 22 is greater than the temperature in the heating zone 12, the phase change material in the microcapsule begins to undergo phase change and release heat, releasing a large amount of stored heat, raising the temperature of the heating zone 12, and realizing the stable transport of heat.

[0046] It should be noted that phase change materials undergo phase changes such as melting or solidification depending on the temperature. During the phase change, they also absorb and release heat. In conjunction with the heat regulation control 33 of this application, they can controllably absorb and release heat, thereby achieving heat transfer between the heating zone 12 and the cooling zone 11, as well as cooling and heating them respectively.

[0047] As a preferred embodiment of this application, such as Figure 3 As shown, the circulation assembly 2 also includes a protective shell 24, a movable hinge portion 25 disposed on the side wall of the protective shell 24, and a temperature sensing element 26 disposed inside the protective shell 24.

[0048] The protective shell 24 serves as the external shell structure of the heat exchange zone 13, protecting and supporting the internal circulation pipe 21 while also providing insulation and heat dissipation. The movable hinge 25 is placed on the surface of the protective shell 24 and can automatically open or close according to actual working needs and the ambient temperature determined by the internal temperature sensor 26, thereby achieving intelligent temperature control and dissipation.

[0049] It should be noted that, since the heat regulation control 33 of this application is based on the Peltier effect, its working efficiency and stability are highly dependent on the temperature difference and heat dissipation conditions of the environments at the hot and cold ends. If the heat dissipation end does not dissipate heat sufficiently, heat accumulation is likely to occur, affecting the heat absorption capacity. Conversely, the heat absorption end may experience large temperature fluctuations and slow temperature response due to excessively high ambient temperatures. Therefore, for the heat exchange zone 13, it is often necessary to ensure that the heat regulation control 33 is in a controllable space. The movable folding part 25 is provided to accommodate... Located on the outer wall of the protective shell 24, which is the rear of the entire refrigerator / heater cabinet, it ensures aesthetics while minimizing the impact on surrounding people and items. It may include structures such as a hinge body, a rotating component, a driving component, and a limiting component. The hinge body can be made of metal plate or composite heat insulation board, and can be opened and closed by designing a louver-like structure. The rotating component can be a rotating shaft or hinge structure, and together with a motor-driven component, it can drive the hinge body to swing at a certain angle. The limiting component is set at the frame or driving component to limit the maximum swing position of the hinge body.

[0050] During use, the temperature inside the protective shell 24, especially near the heat control control 33, is monitored in real time by the temperature sensor 26 inside the protective shell 24. The information is transmitted to the control unit to determine whether the preset temperature threshold is exceeded, and the opening of the folding body is adjusted according to the temperature to avoid excessive internal temperature accumulation, which would affect the normal operation of the heat control control 33.

[0051] Of course, it is understandable that the use of movable folding parts 25 such as louvers for temperature regulation in this application is only an optional implementation method. For other installable structures or devices that can be temperature regulated, this application may also adopt a suitable solution.

[0052] This application also provides a method for using a refrigerator / heater cabinet that simultaneously has cooling and heating functions, based on the aforementioned refrigerator / heater cabinet, such as... Figure 6 As shown, it includes: S1, cooling zone 11 is working and entering the cooling state; S2, the heat control control 33 at the connection of the cooling zone 11 cooperates with the heat absorption part 31 to actively absorb the heat in the cooling zone 11 to the heat transfer medium 22 of the circulation pipe 21; S3, the circulation component 2 drives the heat transfer medium 22 to flow along the preset direction to the heating zone 12; S4. The heat control control 33 at the connection of the heating zone 12 works with the heat release part 32 to release the heat carried by the heat transfer medium 22 to the heating zone 12, thereby raising the temperature of the heating zone 12. S5, the heat transfer medium 22 flows in a closed loop in the circulation pipe 21, and while the cooling zone 11 continues to cool down, the cooling zone 11 and the heating zone 12 are heated simultaneously.

[0053] In step S1, the original compressor or other refrigeration mechanism is installed in the refrigeration space to maintain a stable low temperature environment in the refrigeration zone 11, so that the refrigeration space can serve as a low temperature storage area. During this process, the temperature in the refrigeration zone 11 gradually decreases to a stable level, and the internal heat gradually concentrates under the action of the heat conduction plate 14, providing a basis for subsequent heat transfer.

[0054] In S2, when the cooling space is in a stable cooling state, heat gradually accumulates towards the heat absorption part 31 under the guidance of the heat conduction plate 14. Subsequently, under the active heat absorption effect of the heat regulation control 33, the heat that originally needed to diffuse to the outside in the cooling zone 11 is directed to the first medium box 211 through the heat regulation control 33, so that a close heat exchange and heat conduction path is formed between the heat conduction medium 22 in the first medium box 211 and the circulation pipe 21 and the cooling zone 11.

[0055] Subsequently, in S3, after the heat regulation control 33 and heat absorption part 31 in the cooling space complete heat absorption, the drive structure (such as a pump structure) of the circulation component 2 is activated, causing the heat transfer medium 22 to flow in a predetermined direction in the circulation pipeline 21. During this process, after the heat transfer medium 22 completes heat absorption in the first medium tank 211, it is transported along the conveying section 2131 to the second medium tank 212 in the heating zone 12.

[0056] In this process, the heat-conducting liquid in the heat-conducting medium 22 acts as a heat transfer carrier. The phase change material microcapsules integrated in the heat-conducting liquid will undergo a phase change after absorbing heat, thereby storing the heat stably inside the medium in the form of a combination of sensible heat and latent heat, reducing the heat attenuation during the transport process.

[0057] As for S4, similar to S2, after the heat transfer medium 22 enters the second medium tank 212 along the circulation pipe 21, the heat regulation control 33 set between the heating zone 12 and the second medium tank 212 begins to operate. Its heat release end faces the heating zone 12, and its heat absorption end faces the second medium tank 212. Under the guidance of the heat regulation control 33, the heat stored in the heat transfer medium 22 is directionally released into the heating zone 12, causing the air and inner wall temperature of the heating zone 12 to gradually increase. At the same time, the phase change material microcapsules undergo a reverse phase change during the heat release process of the heat transfer medium 22 and the heat regulation control 33, continuously releasing the stored latent heat to ensure the stability and continuity of the heating process, thereby avoiding the problems of instantaneous heat release and excessive temperature fluctuations.

[0058] Furthermore, in S5, after the heat release process in S4 is completed, the heat is transferred to the heating zone 12. The heat transfer medium 22 returns to the first medium tank 211 from the second medium tank 212 through the return section 2132 to continue the next round of heat absorption, thereby forming a stable closed-loop flow path in the circulation pipeline 21. Through this process, while the cooling zone 11 maintains a low-temperature environment, the heat generated therein is simultaneously transferred to the heating zone 12, achieving simultaneous cooling and heating.

[0059] It is understandable that this application uses the circulation pipe 21 structure in conjunction with the heat control control 33 to realize heat transfer and medium circulation between the heating zone 12 and the cooling zone 11. After one medium circulation, a new circulation is started, thereby realizing the rational allocation and effective utilization of resources to ensure that the cooling and heating functions are realized simultaneously.
