Description

Technical Field

[0001] This application belongs to the technical field of refrigeration and freezing equipment, and particularly relates to a cold energy transfer mechanism for refrigeration and freezing and a refrigerator having the cold energy transfer mechanism. Background Technology

[0002] As people's living standards improve, their demands for refrigerator functionality are increasing. Previously, two compartments—one for refrigeration and one for freezing—were sufficient for consumers. However, with the abundance of food options and rising living standards, modern refrigerators require larger capacities, multi-compartment storage, independently adjustable compartment temperatures, built-in ice makers and chilled water systems, deep-freezing compartments (-20 to -60 degrees Celsius), frost-free cooling, and rapid freezing. Without revolutionary technological advancements in basic refrigeration methods, the ultimate practical problem to solve remains: how to transport cold air to the required compartments.

[0003] However, while traditional compression refrigeration solutions are highly efficient, they have very high requirements for piping, insulation, and high pressure, resulting in high costs and risks such as refrigerant leakage. Summary of the Invention

[0004] The purpose of this application is to provide a cold air transfer mechanism and a refrigerator to solve the technical problems of the high requirements for pipelines, insulation, and high pressure of the compression refrigeration scheme used in the prior art, as well as the risk of refrigerant leakage.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] In a first aspect, this application provides a cold air transfer mechanism, comprising:

[0007] A container for filling a fluid, the fluid being a liquid that does not freeze within the refrigeration temperature range of a refrigerator; the container is connected to inlet and outlet pipes, the inlet and outlet pipes being used to form a closed-loop circulation channel that passes through the cold energy transfer target and transports the fluid;

[0008] The compressor is connected to the container via a cooling pipe and cools the fluid inside the container.

[0009] The above technical solution has the following advantages or beneficial effects:

[0010] This application uses a fluid that does not freeze within the refrigerator's cooling temperature range as a cold energy carrier. It utilizes the advantages of liquids, such as high specific heat, low pressure required for flow, no impact on the refrigeration system after leakage, and the use of environmentally friendly liquids to prevent environmental pollution. Cold energy is stored in the fluid, and through the flow of the fluid, the cold energy is quickly and safely transferred to the target cold energy transfer point. The heat within the target cold energy transfer point is then carried out through inlet and outlet pipes and circulated, ultimately achieving a rapid reduction in the temperature of the target cold energy transfer point.

[0011] The structure of the inlet and outlet pipes is improved, and the inlet and outlet pipes are made into flexible hoses.

[0012] The above technical solution has the following advantages or beneficial effects:

[0013] By utilizing the flexible and deformable characteristics of hoses, they can flexibly adapt to deformations caused by external forces or environmental constraints, which is beneficial for the flexible installation of pipes in refrigerator doors, door hinges, or other special scenarios, effectively improving the environmental adaptability of the cold air transmission mechanism.

[0014] In one embodiment, the inlet and outlet pipes include an input pipe and an output pipe respectively connected between the container and the cold energy transfer target, the output pipe being connected to the bottom of the container, and the input pipe being connected to the container from a location other than the bottom of the container.

[0015] The above technical solution has the following advantages or beneficial effects:

[0016] The fluid in the container can exit from the bottom, reach the target for cold energy transfer, and then return to the inside of the container from the top, thus forming a cycle. This maximizes the utilization of the fluid inside the container for cold energy transfer, thereby improving the utilization rate of the fluid inside the container.

[0017] In one embodiment, the container is also connected to a pump body, which is connected to the inlet and outlet pipes.

[0018] The above technical solution has the following advantages or beneficial effects:

[0019] Using a pump to provide the flow force for the fluid in the container is beneficial for controlling the fluid velocity and improving the overall cooling capacity transfer efficiency of the refrigeration system.

[0020] The above-mentioned pump body configuration is further improved, wherein the inlet and outlet pipes include an input pipe and an output pipe respectively connected between the container and the cold energy transfer target, the output pipe is connected to the bottom of the container, and the pump body is disposed on the output pipe.

[0021] The above technical solution has the following advantages or beneficial effects:

[0022] By placing the pump at the bottom of the container, the pump draws the cooled fluid, which has undergone heat exchange, from the bottom of the container and transfers it to the target of cold energy transfer for further cooling, thus forming a cycle. This effectively maintains the circulation and speed of cold energy transfer, thereby improving the rapid cooling efficiency of the target of cold energy transfer.

[0023] An improvement is made to the layout of the cold pipes connected to the container, wherein the cold pipes penetrate into the inner cavity of the container, and the portion of the cold pipes located in the inner cavity of the container contacts the fluid.

[0024] The above technical solution has the following advantages or beneficial effects:

[0025] At least a portion of the cold pipe is located inside the container, allowing the outer surface of the cold pipe to directly contact the fluid in the container, effectively improving heat exchange efficiency and thus enhancing the freezing effect on the fluid.

[0026] Another improvement is made to the layout of the cold pipes connected to the container, wherein the cold pipes are connected to the outside of the container and the portion of the cold pipes on the container is laid on the outer surface of the container.

[0027] The above technical solution has the following advantages or beneficial effects:

[0028] This solution lays the cold pipes on the outer surface of the container, which reduces the difficulty of installing the cold pipes on the container. Since no splicing is required, the integrity and sealing of the container are ensured, effectively eliminating the risk of leakage. The fluid inside the container exchanges heat with the cold pipes laid on the outer surface through the container wall, ensuring effective cooling of the fluid.

[0029] In one embodiment, the portion of the cold pipe located on the container is arranged in a serpentine pattern.

[0030] The above technical solution has the following advantages or beneficial effects:

[0031] The serpentine arrangement of the cold pipes on the container increases the coverage area of ​​the cold pipes on the container and simultaneously increases the contact area for heat exchange with the fluid, effectively improving heat exchange efficiency.

[0032] In one embodiment, the outer surface of the container has a positioning groove, and a portion of the cold pipe on the outer surface of the container is embedded in the positioning groove.

[0033] The above technical solution has the following advantages or beneficial effects:

[0034] Embedding the cooling pipe within the positioning groove serves two purposes: firstly, it ensures effective fixation of the cooling pipe, preventing it from easily shifting; secondly, the groove's structure reduces heat loss from the cooling pipe, increasing the concentration of heat dissipation.

[0035] In one embodiment, the container end with the positioning groove is recessed inward, so that the interior of the container forms a convex rail that matches the shape of the positioning groove, and the surface of the convex rail is in contact with the fluid.

[0036] The above technical solution has the following advantages or beneficial effects:

[0037] By utilizing the outer surface of the convex rail to contact the fluid inside the container, the contact area with the fluid is effectively increased, thereby improving the heat exchange efficiency of the fluid.

[0038] Secondly, this application provides a refrigerator, including a cabinet and the aforementioned cold air transmission mechanism, wherein the cabinet is configured with a compartment having an opening for taking out or putting in food, and the inlet and outlet pipes on the container are connected to the compartment.

[0039] The above technical solution has the following advantages or beneficial effects:

[0040] The cold air transmission mechanism of this application has a simple structure and occupies little space. It can be installed on mobile refrigerators or vehicle refrigerators, which is beneficial for meeting the installation requirements of small-capacity refrigerators, and installation environments with only narrow spaces or special shapes.

[0041] In one embodiment, the cold energy transfer mechanism further includes an evaporator disposed inside the housing, the compressor being connected to the evaporator, and the evaporator being connected to the container via the cold pipe.

[0042] The above technical solution has the following advantages or beneficial effects:

[0043] The evaporator increases the cooling capacity of the compressor for the refrigerant, which then cools the fluid in the container, thus meeting the cooling requirements of a household refrigerator. Heat exchange occurs between the fluid in the container and the increased-capacity cooling pipes, ensuring that the cooling capacity transferred to the refrigerator compartments meets the freezing or refrigeration needs of a household refrigerator.

[0044] Thirdly, this application also provides another refrigerator, including the aforementioned cold air transmission mechanism, the cold air transmission mechanism further including an evaporator, the compressor being connected to the evaporator, and the evaporator being connected to the container via the cold pipe;

[0045] The refrigerator has a door, and the inlet / outlet pipe on the container is connected to the door.

[0046] The above technical solution has the following advantages or beneficial effects:

[0047] When it is necessary to transport cold energy over long distances or in complex environments, such as refrigerator doors that require cold energy transmission, the cold energy transmission mechanism of this application can be used to supply cooling to the door that requires cold energy transmission, thereby improving the applicability of the cold energy transmission mechanism of this application.

[0048] The beneficial effects of the cold energy transfer mechanism and refrigerator provided in this application are as follows: Compared with the prior art, the cold energy transfer mechanism of this application achieves cooling by transporting liquid substances containing cold energy through pipelines to the target that needs cold energy through a secondary exchange of cold energy.

[0049] The cold air transfer fluid of this application is a low-pressure liquid substance, which is safe and can be used for cold air transfer in low-pressure pipelines. Even if the low-pressure liquid substance leaks locally in the low-pressure pipeline, it will not cause significant harm to the human body or the refrigerator's refrigeration system. In addition, the cold air transfer fluid of this application is a low-pressure liquid substance. Utilizing the high specific heat and large amount of heat carried per unit volume of liquid, the low pressure required for the flow process is conducive to the rapid and large-volume transfer of cold air. This eliminates the high requirements for insulation, sealing, strength, and sealing connections in the construction of air duct systems, effectively reducing the design difficulty of the entire refrigeration system inside the refrigerator, ensuring safety and reliability, and helping to reduce production costs.

[0050] The refrigerator of this application has this cold energy transfer mechanism, which uses the fluid in the container as an energy storage substance. It can also serve as a supplement to the refrigerator's refrigeration system, which helps to mitigate temperature fluctuations in the refrigerator's compartments and reduces the frequency of compressor starts, thereby lowering energy consumption. In addition, the fluid in the container can also serve as backup cold energy, especially during power outages, allowing the refrigerator to continue operating for a certain period of time, thus significantly extending the low-temperature environment inside the refrigerator.

[0070] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0071] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0072] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "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 application 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 limitations on this application.

[0073] 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 application, "multiple" means two or more, unless otherwise explicitly specified.

[0074] Traditional refrigeration methods in the industry rely on compression technology, which cools by transferring heat. This is currently one of the most efficient known refrigeration methods, with a cooling efficiency more than twice that of traditional methods. However, this method requires a sealed piping system capable of withstanding high pressure. When a specific compartment inside the refrigerator needs cooling, the cooling pipes are typically extended directly to that compartment; alternatively, a fan generates airflow to blow cooling energy through a sealed duct to the compartment requiring cooling. Currently, both of these methods present significant technical challenges and have unsatisfactory cooling transfer effects.

[0075] The extended refrigerant pipe solution involves extending the refrigeration pipes directly to the target room. As the name suggests, this increases the pipe length. The pipes carry high-pressure gaseous and liquid refrigerant, requiring extremely high sealing and strength. Furthermore, pipe branch joints need to be welded to prevent refrigerant leaks and potential hazards. In this solution, the compression refrigeration method keeps the refrigerant in a high-temperature, high-pressure environment. Any leak will destroy the entire refrigeration system. Therefore, the internal piping operation and welding requirements of this refrigeration system are very high. Especially when multiple rooms need to control different temperatures, more branch pipes or duct systems are required, further increasing manufacturing difficulty, production defects, and maintainability.

[0076] For solutions using fan-driven cooling, the cold air from the evaporator inside the refrigerator is transferred by the airflow generated by a rotating fan. This requires a well-sealed air duct system, and the entire system occupies a significant amount of internal space. Typically, the air duct system is designed within the refrigerator's foam insulation layer. This system needs sufficient insulation thickness to maintain adequate distance from the external environment, different internal compartment temperatures, and drain pipes, preventing risks such as icing, cold leakage, and impact on the refrigerator's foam expansion. Simultaneously, the air duct system must withstand the high pressure and high temperature generated during the foaming process of the refrigerator's insulation layer. Therefore, this solution requires stringent treatment of the air duct system in terms of insulation, sealing, strength, and joint connections to minimize cold air loss during transmission. Because this solution uses compression refrigeration, the cold air carrier can be considered a gaseous substance. The low specific heat and small heat capacity per unit volume of gaseous substances limit the rapid and large-volume transfer of cold air. If a large amount of cooling is required, this solution will require a sufficiently large refrigeration system, which means higher costs and lower system reliability.

[0077] When long-distance cooling or cooling in complex environments is required, both of the above solutions are difficult to implement and the actual cost is relatively high.

[0078] In response to the above situation, the applicant has painstakingly researched and designed a novel cold energy transfer mechanism. This breaks away from the conventional thinking of industry professionals (which refers to traditional cold energy transfer methods such as extending the refrigerant pipeline to the target compartment or using airflow to transfer cold energy through ducts). The applicant creatively proposes a novel cold energy transfer mechanism and a refrigerator equipped with this mechanism. This mechanism utilizes a safe, atmospheric-pressure fluid as the cold energy carrier. Leveraging the advantages of liquids—high specific heat, low pressure required for flow, no impact on the refrigeration system after leakage, and the use of environmentally friendly liquids to prevent pollution—the cold energy is stored in the fluid. Through fluid flow, a large amount of cold energy is quickly and safely transferred to the compartment requiring cooling, thereby removing heat from the compartment and circulating it, ultimately achieving a rapid temperature reduction. This effectively solves the problems of traditional compression refrigeration methods, which have high requirements for piping, insulation, and high pressure, and also carry the risk of refrigerant leakage. Details of this application's solution are provided below.

[0079] Please see Figure 1 The cold energy transfer mechanism provided in this application embodiment includes at least a container 1 and a compressor 2.

[0080] Container 1 is used to fill a fluid, preferably a liquid that does not freeze within the refrigerator's cooling temperature range. Using this liquid as a cooling medium ensures safety and reliability, even if leakage occurs. For example, the fluid could be a mixture of ethylene glycol, which meets the requirement of not freezing at -60 degrees Celsius.

[0081] Container 1 is connected to inlet and outlet pipes 3, which include output and input pipes on container 1. The inlet and outlet pipes 3 are used to form a closed-loop circulation channel for transporting fluid through the cold energy transfer target 4. Container 1 is connected to the cold energy transfer target 4 through the inlet and outlet pipes 3, forming a closed-loop circulation channel for transporting fluid. The cold energy transfer target 4 can be a compartment for storing refrigerated items, such as a compartment in a refrigerator; or it can be a special container, etc. In this way, the fluid in container 1 can flow in the circulation channel, carrying away the heat from the cold energy transfer target 4 and circulating it, thereby rapidly lowering the temperature of the cold energy transfer target 4.

[0082] Compressor 2 is connected to container 1 via cold pipe 21 to cool the fluid inside container 1. In other words, the output of compressor 2 in a conventional refrigeration system is directly connected to container 1 to cool the fluid inside, maintaining a low temperature. This low-temperature fluid then acts as a cooling carrier, transporting heat away from the target 4 and circulating cooling energy to achieve rapid cooling.

[0083] Compared with the prior art, the cold energy transfer mechanism provided in this application achieves cooling by transporting liquid substances containing cold energy to the target that needs cooling through pipelines via a secondary cold energy exchange method.

[0084] Compared to conventional methods of directly transporting refrigerant, which uses a high-pressure liquid and requires high-pressure pipelines, posing a risk of contamination in case of leakage, this application utilizes a low-pressure liquid fluid for cold energy transfer. This fluid is safe and can be used in low-pressure pipelines. Even if a localized leak occurs in the low-pressure pipeline, it will not cause significant harm to people or the refrigerator's refrigeration system.

[0085] Compared with the method of using air to transfer cold energy, the cold energy transfer fluid in this application is a low-pressure liquid substance. It takes advantage of the liquid's high specific heat and large amount of heat carried per unit volume, and the low pressure required for the flow process, which is conducive to the rapid and large-scale transfer of cold energy. It eliminates the high requirements for insulation, sealing, strength, and sealing connection of the air duct system, effectively reduces the design difficulty of the entire refrigeration system inside the refrigerator, is safe and reliable, and helps to reduce production costs.

[0086] Although the cold energy transfer mechanism of this application performs a secondary exchange of cold energy compared to traditional refrigeration schemes, this exchange can take place inside the refrigerator's insulation layer. According to the law of conservation of cold energy, the actual cooling capacity does not leak into the external environment of the refrigerator, thus having no impact on the refrigerator's energy consumption. When adding the secondary cold energy exchange, a liquid, non-toxic, and reliable substance (a substance that is liquid at -18 degrees Celsius or lower, such as ethylene glycol solution, salt water solution, organic solution, alcohol, etc.) is used. The specific heat of this type of liquid substance is tens of times greater than that of traditional refrigerants. This fluid exchanges heat with the cold pipe 21 through which the refrigerant flows in the container 1, allowing the fluid in container 1 to act as an energy storage substance, supplementing the refrigerator's refrigeration system. This helps to mitigate temperature fluctuations in the refrigerator's compartments and reduces the frequent starting of the compressor 2, thereby lowering energy consumption.

[0087] In addition, the fluid in container 1 can also serve as backup cooling capacity, especially during power outages, allowing the refrigerator to continue operating for a certain period of time. This can quickly and effectively address situations where a large amount of cooling capacity is needed inside the refrigerator (e.g., ice maker systems, quick-cooling zones, short-term shutdowns of the refrigerator due to power outages or unstable voltage), thereby significantly extending the low-temperature environment inside the refrigerator.

[0088] In practical applications, the refrigeration system in traditional refrigerators is generally designed into the cabinet. When cooling is needed on the movable door, if cold air is supplied directly to the door via refrigerant pipes, the synchronization of the pipes' rotation and translation during door movement needs to be addressed. If a fan is used to deliver cooling from the cabinet to the door, numerous issues need to be resolved, such as how to seal the air duct system when the door leaves the cabinet, and issues like cold leakage, condensation, and insulation at the air inlet and outlet. Currently, there are no satisfactory solutions to these problems.

[0089] Therefore, in the cold energy transfer mechanism provided in the embodiments of this application, please refer to... Figure 1 The inlet and outlet pipes 3 connected to the container 1 can preferably be flexible hoses that can be bent and deformed as a whole or in parts.

[0090] Since the cold energy carrier used in this application is a low-pressure liquid substance, it does not require high-pressure pipelines for transmission. Therefore, low-pressure liquid substances can be transmitted in low-pressure pipelines. The low-pressure pipelines can use the aforementioned flexible hoses, which can achieve twisting and rotation of the pipelines within a certain rotation angle range. This is beneficial for solving the problem of long-distance cold energy transmission or cold energy transmission in relatively complex environments (such as delivering cold energy to the refrigerator door, which requires overcoming the door's rotational movement).

[0091] Among them, the flexible hose can preferably be a commonly used corrugated pipe, which can be used to meet the opening and closing changes of the refrigerator body and door by utilizing the expansion and contraction function of the corrugated pipe.

[0092] Therefore, the cold energy transmission mechanism provided in this application embodiment uses low-pressure liquid to transmit cold energy. Thus, traditional low-pressure hoses such as corrugated pipes can be used as fluid transmission pipelines. By utilizing the flexible and deformable characteristics of the hoses, they can flexibly adapt to the overall or partial deformation caused by external forces or environmental constraints. This is beneficial for the flexible setting of pipelines in refrigerator doors, door hinges, or other special scenarios, effectively improving the environmental adaptability of the cold energy transmission mechanism.

[0093] For the specific structure of the inlet / outlet pipes 3 connected to container 1, please refer to one embodiment of this application. Figure 2 The inlet and outlet pipes 3 on container 1 include an input pipe 31 and an output pipe 32 that are respectively connected between container 1 and cold energy transfer target 4. The output pipe 32 is connected to the bottom of container 1, and the input pipe 31 can be connected to container 1 from a part other than the bottom of container 1.

[0094] In this embodiment, as Figure 2 As shown, container 1 can preferably be a rectangular box, having at least a top surface, a bottom surface, and four sides. Input pipe 31 is connected to the top surface of container 1 and enters the interior of container 1 from the top. Output pipe 32 is connected to the bottom surface of container 1 and communicates with the bottom output port of container 1.

[0095] In this way, the fluid in container 1 can be output from the bottom of container 1, and after reaching the cold energy transfer target 4, it can return to the inside of container 1 from the top, thus forming a cycle. This maximizes the utilization of the fluid inside container 1 for cold energy transfer, thereby improving the utilization rate of the fluid inside container 1.

[0096] In other embodiments (not shown in the figures), the input pipe 31 can also be connected to the side of the container 1, preferably on any side near the top surface of the container 1. This facilitates adaptation to the installation environment of the container 1, thereby making it easier to set up the inlet and outlet pipes on the container 1 and effectively improving the flexibility of setting up connecting pipes on the container 1.

[0097] To increase the flow rate of cold air transfer and overcome the pressure difference between high and low points, in one embodiment of this application, please refer to... Figure 2 The container 1 is also connected to a pump body 5, which is connected to the inlet and outlet pipes 3.

[0098] The pump body 5 can preferably be a water pump that meets the power requirements and has a small size. The pump body 5 provides the flow force for the fluid in the container 1, which is beneficial to control the flow rate of the fluid and improve the cold energy transfer efficiency of the entire refrigeration system.

[0099] In this embodiment, please refer to the following: Figure 1 andFigure 2 The output pipe 32 on container 1 is connected to the bottom of container 1. The pump body 5 can preferably be set at the bottom of container 1. Specifically, the pump body 5 can be set at a height lower than the bottom of container 1, so that the pump body 5 is set on the output pipe 32.

[0100] In this way, with the fluid returning from the top of container 1, the pump body 5 is set at the bottom of container 1. The pump body 5 is used to extract the cooled fluid after heat exchange inside container 1 from the bottom of container 1 and transfer it to the cold energy transfer target 4 for cooling again and forming a cycle. This effectively maintains the cycle and speed of cold energy transfer, thereby improving the rapid cooling efficiency of the cold energy transfer target 4.

[0101] In the cold energy transfer mechanism of this application, it is crucial to quickly bring the fluid in container 1 to the freezing temperature. The fluid temperature inside container 1 is primarily controlled by the compressor 2 connected to the cold pipe 21, which rapidly transfers cold energy to the fluid inside container 1. Therefore, the placement of the cold pipe 21 on container 1 is critical to maximizing heat exchange between the fluid inside container 1 and the cold pipe 21, ensuring the fluid reaches the freezing temperature and is transferred to the cold energy transfer target 4.

[0102] Therefore, in the cold air transfer mechanism of this application, the arrangement of the cold pipe 21 connected to the container 1 includes, but is not limited to, the following forms:

[0103] In one embodiment of this application, please refer to Figure 3 The cold pipe 21 is inserted into the inner cavity of the container 1 and preferably covers the entire inner cavity of the container 1. This is equivalent to immersing the cold pipe 21 in the fluid, so that the part of the cold pipe 21 located in the inner cavity of the container 1 is in direct contact with the fluid, which effectively improves the heat exchange efficiency and thus improves the freezing effect on the fluid.

[0104] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 4 and Figure 5 The cold pipe 21 is connected to the outside of the container 1. Specifically, the part of the cold pipe 21 located on the container 1 can be laid on the outer surface of the container 1. The fluid inside the container 1 exchanges heat with the cold pipe 21 laid on the outer surface of the container through the wall of the container 1, so as to ensure the freezing effect of the fluid.

[0105] Compared to the method described above where the cooling pipe 21 is inserted into the container 1, the aforementioned method requires the cooling pipe 21 to be inserted into the container 1, and the insertion point needs to be sealed; otherwise, leakage is likely to occur. In this embodiment, the cooling pipe 21 is laid on the outer surface of the container 1. It can be fixed to the outer surface of the container 1 by welding or other methods, which helps to reduce the difficulty of installing the cooling pipe 21 on the container 1. Since there is no need to perform insertion treatment on the container 1, the integrity and sealing of the container 1 can be ensured, effectively eliminating the risk of leakage.

[0106] For the configuration of the cold pipe 21 in the two embodiments described above, the portion of the cold pipe 21 located on the container 1 can be arranged in a serpentine pattern to increase the coverage area of ​​the cold pipe 21 on the container 1 and at the same time increase the contact area for heat exchange with the fluid, thereby effectively improving the heat exchange efficiency.

[0107] As an example, such as Figure 3 As shown, the cold pipe 21 that penetrates into the interior of container 1 is arranged in a serpentine pattern. Specifically, it enters the interior of container 1 from near the top, then serpentinely arranges itself from top to bottom within the interior of container 1, and exits from near the bottom of container 1 to the outside. In this way, the internal space of container 1 is covered to the maximum extent, thereby improving the efficiency and uniformity of cold energy transfer.

[0108] like Figure 5 As shown, the cold pipes 21 laid on the outer surface of container 1 can also be arranged in a serpentine pattern. Specifically, they can be laid from one side of container 1 on the outer surface of one end face of container 1, then arranged in a serpentine pattern on the outer surface of container 1, and finally extend from the other side of container 1. In this way, the cold pipes 21 can be covered to the maximum extent on one end panel of container 1, and heat exchange can be carried out between the end panel and the fluid inside container 1, effectively improving the efficiency and uniformity of cold transfer.

[0109] Regarding the aforementioned issue that placing the cold pipe 21 on the outer surface of the container 1 prevents the cold pipe 21 from directly contacting the fluid, thus affecting the heat exchange efficiency between the fluid and the cold pipe 21.

[0110] Therefore, in one embodiment of this application, please refer to Figure 6 The outer surface of container 1 also has a positioning groove 11, and the portion of cold pipe 21 on the outer surface of container 1 is embedded in the positioning groove 11.

[0111] In this embodiment, the shape of the positioning groove 11 is matched with that of the cold pipe 21. A serpentine groove is preferably used so that the cold pipe 21 is embedded in the positioning groove 11, which effectively ensures the fixing effect of the cold pipe 21, avoids the cold pipe 21 from easily shifting, and thus improves the high pressure fixing strength of the cold pipe 21.

[0112] Furthermore, the cold pipe 21 is embedded in the positioning groove 11 on the outer surface of the container 1, and the groove wall of the positioning groove 11 surrounds the outer periphery of the cold pipe 21, which helps to reduce the diffusion of cold energy from the cold pipe 21. In this way, the groove structure of the positioning groove 11 reduces the loss of cold energy from the cold pipe 21 and improves the concentration of cold energy dissipated from the cold pipe 21.

[0113] For further details, please refer to Figure 6 The container 1 with the positioning groove 11 is recessed into the interior of the container 1, so that the interior of the container 1 has a convex rail (not shown) that matches the shape of the positioning groove 11, so that the surface of the convex rail is in contact with the fluid inside the container 1.

[0114] Specifically, in this embodiment, the container 1 has a convex rail inside that matches the shape of the positioning groove 11. The cold pipe 21 is laid in the positioning groove 11. The other side of the positioning groove 11 is a convex rail inside the container 1. The surface of the convex rail is in direct contact with the fluid inside the container 1, which effectively increases the contact area with the fluid and thus improves the heat exchange efficiency of the fluid.

[0115] Please see Figure 7 This application provides a refrigerator, including a cabinet and a cold air transmission mechanism according to this application. The cabinet is constructed with compartments having access ports, which can be understood as various compartments in the refrigerator for placing refrigerated items. Inlet and outlet pipes 3 on the container 1 are connected to the compartments to cool them.

[0116] Therefore, the cold air transmission mechanism of this application has a simple structure and occupies little space. It can be installed on mobile refrigerators or vehicle refrigerators, which is beneficial to meet the installation requirements of refrigerators with small volume and only narrow space or special shape (such as the special shape or narrow space of the vehicle where the vehicle refrigerator is located).

[0117] Please see Figure 8 This application also provides another refrigerator, including the cold air transmission mechanism of this application. The cold air transmission mechanism further includes an evaporator 6, which is disposed inside the refrigerator body. The compressor 2 is connected to the evaporator 6, and the evaporator 6 is connected to the container 1 via a cold pipe 21. The refrigerator has a compartment 7 for storing refrigerated items, and the inlet / outlet pipes 3 on the container 1 are connected to the compartment 7.

[0118] In this way, the evaporator 6 increases the cooling capacity of the compressor 2 for the refrigerant, and then cools the fluid in the container 1, thereby meeting the cooling capacity requirements of a household refrigerator. The fluid in the container 1 exchanges heat with the cold pipe 21, which has been amplified in cooling capacity, so that the cooling capacity transferred to the compartment 7 meets the freezing or refrigeration requirements of a household refrigerator.

[0119] The cold air transmission mechanism of this application is further optimized in the setting of a household refrigerator. In one embodiment of this application (not shown in the figure), the refrigerator has multiple compartments 7, and the container 1 is connected to multiple sets of inlet and outlet pipes 3, which are respectively connected to each compartment 7.

[0120] Therefore, by utilizing the fluid in container 1, cooling capacity is transferred to each compartment 7 of the refrigerator, effectively ensuring efficient cooling capacity transfer. The fluid in container 1 can also serve as an energy storage substance, supplementing the refrigeration of the refrigerator system, mitigating temperature fluctuations in compartment 7, thereby reducing the frequent starting of compressor 2 and lowering the refrigerator's energy consumption. The fluid in container 1 can also act as backup cooling capacity, especially during power outages, allowing the refrigerator to continue operating for a certain period, thus significantly extending the low-temperature environment inside the refrigerator.

[0121] Furthermore, in one embodiment of this application, a control valve (not shown in the figure) is also connected to the container 1. The control valve is used to control the opening and closing of the inlet and outlet pipes 3 of each group respectively.

[0122] In this way, the cooling supply of each compartment 7 on the refrigerator can be started and stopped, effectively improving the controllability of cold energy transmission and thus improving the performance of the cold energy transmission system of this application.

[0123] Please see Figure 9 This application also provides a third type of refrigerator, including the cold air transmission mechanism of this application. The cold air transmission mechanism further includes an evaporator 6, a compressor 2 connected to the evaporator 6, and a cold pipe 21 connecting the evaporator 6 and the container 1. The refrigerator has a door 8, and the inlet / outlet pipes 3 on the container 1 are connected to the refrigerator door 8.

[0124] Therefore, when it is necessary to transport cold energy over long distances or in complex environments, such as refrigerator doors 8 that require cold energy transmission, the cold energy transmission mechanism of this application can be used to supply cold energy to the door 8 that requires cold energy transmission. This effectively eliminates many problems that traditional duct systems require, such as sealing, cold leakage at the air inlet and outlet, condensation, and insulation, thereby improving the applicability of the cold energy transmission mechanism of this application.

[0125] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
