Description

Technical Field

[0001] The utility model relates to the technical field of defrosting of refrigerators, and in particular, to a defrosting component and a refrigeration device. Background Art

[0002] At present, the defrosting systems of refrigeration devices such as refrigerators and freezers usually adopt metal tube heaters to achieve defrosting by heating. In related technologies, after the defrosting function is turned on, it is necessary to first heat the air and then transfer the heat to the frost layer through convection. The overall time is relatively long, the defrosting effect is poor, and it will cause a large temperature rise after the hot air flows into the chamber. Summary of the Utility Model

[0003] The utility model aims to at least solve the technical problem of poor defrosting effect existing in the prior art or related technologies.

[0004] In view of this, an embodiment of the first aspect of the utility model provides a defrosting component.

[0005] An embodiment of the second aspect of the utility model provides a refrigeration device.

[0006] To achieve the above object, an embodiment of the utility model provides a defrosting component, including: a first tube body, the interior of the first tube body is hollow to form a heating cavity, and at least one end of the first tube body is provided with an assembly port; a heating element, disposed in the heating cavity, and one end of the heating element is provided with a connection terminal; a connecting wire, one end of the connecting wire is connected to the connection terminal; a sealing member, disposed at one end of the first tube body, and one end of the sealing member is provided with a first hole section for inserting the first tube body, and the other end is provided with a second hole section, the second hole section is communicated with the first hole section, and the connecting wire and / or the connection terminal extend out of the second hole section; at least part of the second hole section is filled with a sealing glue corresponding to the connection terminal and / or the connecting wire.

[0007] According to the defrosting component proposed by the utility model, the defrosting efficiency is improved, the energy consumption is reduced, and its working stability under humid and extreme temperature conditions is optimized. By introducing a heating element made of graphene material, the heat conduction efficiency can be effectively improved, the heating speed can be accelerated, the latent heat and temperature rise can be reduced, and at the same time, the problems of high energy consumption and temperature rise existing in traditional metal heaters can be effectively solved.

[0008] Specifically, the defrosting component includes a first tube body, a heating element, a connecting wire and a sealing member. Among them, the interior of the first tube body is hollow to form a heating cavity for accommodating the heating element, and the first tube body can prevent the heating element from being damaged by the external environment (such as humidity, dust, mechanical impact, etc.). At the same time, by providing an assembly port at at least one end of the first tube body, the interior can be sealed in cooperation with the sealing member under the action of the assembly port.

[0009] Among them, by arranging the heating element in the heating cavity, utilizing the structural characteristics of graphene, adapting its shape to the tubular structure of the first tube body, a three-dimensional tubular structure is formed on the basis of the two-dimensional structure of graphene, further enhancing the heat conduction performance. Among them, the heating element is fixed in the heating cavity of the first tube body, and one end is connected to the wire through the connection terminal to ensure that the current can smoothly pass through the heating element to generate heat. Due to the high thermal conductivity of the graphene material, it can be quickly heated and transfer heat through two ways: radiation and convection. Since graphene has the characteristic of low latent heat, it is more helpful to quickly cool down after the heating stops, reducing the temperature rise and energy consumption during the defrosting process.

[0010] It should be added that the connecting wire is used to connect the power supply to the connection terminal of the heating element to ensure that the current can reach the heating body smoothly. One end of the connecting wire is connected to the connection terminal of the heating element, and the other end passes through the second hole section of the seal and is connected to an external power supply or control system.

[0011] It should be emphasized that in this solution, by setting the seal and arranging two seal sections inside, namely the first hole section and the second hole section that are connected and communicate with each other. Among them, the first hole section is used to insert the first tube body, and the second hole section is used for the connecting wire or connection terminal to pass through. Under the action of the seal, it can effectively prevent external water vapor from entering the inside of the first tube body, ensure that the electrical connection part of the heating element and the connecting wire remains dry, and prevent short circuit or damage. At the same time, certain mechanical support and protection can be provided through the self-structure of the seal to prevent damage to the wire and terminal during the installation process.

[0012] Furthermore, by injecting glue, that is, filling sealant, into part or all of the second hole section of the seal, the partial gaps where the connection terminal and the connecting wire extend in the second hole section can be effectively sealed, and at the same time, the live connection terminal and the connecting wire can be insulated, thereby achieving double-layer insulation sealing and improving the sealing and insulation effects.

[0013] In some technical solutions, optionally, the seal includes a shaft shoulder, and a first connection part and a second connection part respectively arranged at both ends of the shaft shoulder; among them, the first hole section is arranged in the first connection part, and the second hole section is arranged in part of the first connection part, the shaft shoulder and the second connection part.

[0014] In this technical solution, the structure of the seal includes a shaft shoulder, a first connection part and a second connection part. Among them, the shaft shoulder is the middle part of the seal, used to connect the first connection part and the second connection part. The shaft shoulder, the first connection part and the second connection part are an integral structure. As a relatively wide part of the seal, the shaft shoulder provides enhanced mechanical strength through its larger contact area, helping the seal to maintain its shape and position when subjected to external forces (such as mechanical stress during installation or operation).

[0015] On this basis, the first connecting part is one end part of the seal, which is internally provided with a first hole section for connecting the assembly port of the first pipe body. The first pipe body is inserted into the first hole section to achieve a sealed connection. It can be understood that under the action of the first connecting part, the first pipe body can be firmly fixed in the seal to prevent external water vapor or impurities from entering the heating cavity. The second connecting part is located at the other end of the seal and is provided with a second hole section. The second hole section not only penetrates the second connecting part but also extends into the shaft shoulder and part of the first connecting part. The second connecting part is mainly responsible for leading out the connecting wire or terminal from the seal while maintaining the sealing effect. Since the extension of the second hole section covers the first connecting part, the shaft shoulder, and the second connecting part, the tightness of the entire path is ensured when the wire passes through, thereby preventing water vapor from entering.

[0016] The first connecting part and the second connecting part are respectively located at both ends of the seal, are connected by the shaft shoulder, and each undertake the key tasks of sealing and connection. The first hole section and the second hole section are respectively located in the first connecting part and the second connecting part and are penetrated by the shaft shoulder to ensure the airtightness and watertightness of the entire seal during connection.

[0017] In some technical solutions, optionally, the cross-sectional area of the second connecting part is smaller than that of the shaft shoulder, and the cross-sectional area of the first connecting part is smaller than that of the shaft shoulder.

[0018] In this technical solution, the size of the shaft shoulder is larger, and the sizes of the first connecting part and the second connecting part are both smaller than that of the shaft shoulder. Specifically, the cross-sectional area of the second connecting part is smaller than that of the shaft shoulder, and the cross-sectional area of the first connecting part is smaller than that of the shaft shoulder. By defining the shaft shoulder with a larger size, the safety of assembly can be improved during the installation process. Since the first pipe body is inserted into the first hole section of the first connecting part, the pipe diameter of the first pipe body must be smaller than the size of the shaft shoulder. Therefore, under the action of the shaft shoulder, the possibility of direct collision between the first pipe body and the external structure can be reduced, and the shaft shoulder plays a certain protective role.

[0019] In some technical solutions, optionally, the second connecting part is in the shape of a cuboid, and the defrosting assembly includes: a glue injection port provided on the side wall of the second connecting part and communicating with the second hole section.

[0020] In this technical solution, by designing the second connecting part in the shape of a cuboid, the wall surface where the glue injection port is located can be a plane, which is more convenient for glue injection operation. At the same time, when the second connecting part is in the shape of a cuboid, the entire seal is not a complete rotating body. During assembly, it is easier for manual or machine to hold, and it is also easy to distinguish the posture of the seal, so as to improve the installation efficiency. It should be noted that a glue injection port communicating with the second hole section is provided on the side wall of the second connecting part, allowing glue to be injected into the first pipe body and the seal through the glue injection port after assembly to achieve sealing.

[0021] It can be understood that the glue will fill the gap between the second connecting part and the wire, further enhancing the sealing performance and preventing water vapor from infiltrating. Further, the injected glue (such as silicone glue) can form a waterproof barrier after curing, ensuring that the electrical connection part of the connecting wire remains dry and avoiding short circuits or other electrical faults.

[0022] The setting of the glue injection port can effectively fill the gap during the assembly process, enhance the waterproof performance, and ensure the reliability of the heating element and the connecting wire in humid and extreme temperature environments.

[0023] In some technical solutions, optionally, it further includes: a positioning protrusion, which is provided on the same side wall of the second connecting part as the glue injection port.

[0024] In this technical solution, a glue injection port and a positioning protrusion are provided on the same side wall of the second connecting part. It can be understood that the positioning protrusion protrudes from the surface of the side wall of the second connecting part and is usually designed as a small protruding part, located on the side wall of the second connecting part and adjacent to the glue injection port.

[0025] It can be understood that the main function of the positioning protrusion is to help determine the relative circumferential position of the seal after being assembled with the first pipe body during the assembly process. The positioning protrusion can be used as a comparison reference point during installation. By setting it on the same side wall as the glue injection port, since the second connecting part is in the shape of a cuboid, the circumferential positions of the positioning protrusion and the glue injection port on the second connecting part are approximately the same. The positioning protrusion can be designed as the uppermost part of the entire seal. During installation, only by adjusting the easily distinguishable structure of the positioning protrusion to the upper side of the gravity direction, it is more convenient to align and ensure that the seal maintains the correct position during installation, avoiding seal failure caused by misalignment.

[0026] The design of the positioning protrusion ensures that during the assembly process, the second connecting part can accurately dock with other components, reducing seal problems caused by poor docking.

[0027] In some technical solutions, optionally, it further includes: a sealing thread, which is provided on the inner wall of the first hole section.

[0028] In this technical solution, by setting a sealing thread on the inner wall of the first hole section, when the first pipe body is assembled, the sealing thread can form a closer contact surface, reducing the infiltration of water vapor or air, significantly improving the sealing performance, and protecting the internal heating element and connecting wire.

[0029] In some technical solutions, optionally, it further includes: a second pipe body, which is provided at one end of the first pipe body, and the connection position of the connecting wire and the connecting terminal is inside the second pipe body, and the connecting wire extends out of the second pipe body.

[0030] In this technical solution, the second tube body is an independent tubular structure provided at one end of the first tube body. The internal space of the second tube body is used to accommodate the connecting wire and the connecting terminal. Specifically, the second tube body provides space for the connection between the connecting wire and the connecting terminal, and also provides physical protection against the influence of the external environment (such as moisture, dust, mechanical shock, etc.) on the electrical connection.

[0031] It should be emphasized that in this solution, the connecting wire and the connecting terminal are connected inside the second tube body. Placing the connection position inside the second tube body can effectively prevent the influence of external factors (such as water vapor and dust) on the electrical connection and reduce the risk of short circuit or failure.

[0032] One end of the connecting wire extends out of the second tube body, facilitating connection to an external power source or control system, and allowing the operator to quickly make an electrical connection.

[0033] In some technical solutions, optionally, it includes: a heat shrinkable sealing tube provided outside the second tube body and the connecting wire.

[0034] In this technical solution, by providing a heat shrinkable sealing tube outside the second tube body and the connecting wire, it will shrink when heated, thus tightly wrapping around the second tube body and the connecting wire to form an effective sealing layer to prevent the infiltration of water vapor, dust and other external pollutants.

[0035] It can be understood that the heat shrinkable sealing tube is a tubular material with heat shrinkable properties, usually made of polyolefin or other thermoplastic materials.

[0036] In some technical solutions, optionally, the heating element is a graphene heating sheet, and the heating element extends along the axial direction of the first tube body.

[0037] In this technical solution, by restricting the heating element to be sheet-shaped, specifically a graphene heating sheet, whose axial dimension is much larger than the thickness dimension of the vertical sheet, there will be greater radiant energy in the radial direction, so as to facilitate the expansion of the defrosting area, be able to transfer heat more effectively, quickly melt the frost layer, shorten the defrosting time, and improve the overall defrosting efficiency.

[0038] In some technical solutions, optionally, the inside of the first tube body is vacuum.

[0039] By evacuating the inside of the first tube body, the heat loss during heat transfer can be effectively reduced, the heating efficiency can be improved. At the same time, since the inside of the first tube body is in a vacuum state, to a certain extent, the service life of the heating element located inside can be extended, and the oxidation of the first tube body can be slowed down.

[0040] An embodiment of the second aspect of this application provides a refrigeration device, including: an evaporator; any one of the above defrosting assemblies provided on one side of the evaporator.

[0041] The refrigeration equipment provided by this application includes an evaporator and a defrosting component. The defrosting component is arranged on one side of the evaporator. The evaporator is responsible for absorbing the heat of the surrounding environment, causing the refrigerant to turn into a gas during evaporation, thereby achieving the refrigeration effect. The defrosting component can quickly melt the frost layer on the surface of the evaporator through the efficient heating of the heating element, ensuring that the evaporator maintains good heat exchange efficiency during operation.

[0042] Since the refrigeration equipment includes any of the above defrosting components, it has the beneficial effects of any of the above defrosting components, which will not be elaborated here.

[0043] Among them, the refrigeration equipment includes, but is not limited to, refrigerators, freezers and other equipment with refrigeration functions that will frost during operation.

[0044] Furthermore, the number of defrosting components is one, and the defrosting component is located below the evaporator.

[0045] By selecting one defrosting component and placing the defrosting component below the evaporator, the defrosting component located below the evaporator can more effectively use the methods of heat radiation and convection to transfer heat to the evaporator and quickly melt the frost layer.

[0046] Furthermore, insert the first tube body into the first hole section of the seal, and thread the connecting wire through the seal; when the first tube body moves to the glue injection position, inject sealant through the glue injection port of the seal until the sealant overflows from the first hole section and / or the second hole section; let the defrosting component after glue injection stand at room temperature for the first duration; wherein, the glue injection position is the position where one end of the first tube body abuts against the axis of the first hole section.

[0047] This solution mainly provides a sealing method to achieve the assembly and glue injection of the defrosting component. Specifically, insert the end of the first tube body into the first hole section of the seal to ensure a preliminary connection between the two. Through the insertion, the connection between the first tube body and the seal begins to form, laying a foundation for subsequent sealing and protection. The insertion operation ensures the correct position of the first tube body in the seal, providing space for subsequent glue injection and the threading of the connecting wire.

[0048] Then thread one end of the connecting wire through the second hole section of the seal. By threading the connecting wire, it is ready to be connected to an external power source or control system to ensure the smooth progress of the electrical connection. Among them, when threading the wire, the design ensures that the sealing performance of the seal is not affected and prevents water vapor from infiltrating.

[0049] Move the first tube body to the glue injection position, that is, the position where one end of the first tube body abuts against the axis of the first hole section, and then inject sealant through the glue injection port. Injecting the sealant fills the gap between the first hole section and the first tube body, forming a tighter seal to prevent water vapor from seeping in. The injected sealant forms a waterproof barrier after curing, ensuring the electrical safety of the connection.

[0050] Continue to inject the sealant until the glue overflows from the first hole section and / or the second hole section, indicating that the sealant has fully filled all the gaps, ensuring that there are no omissions and enhancing the sealing effect.

[0051] After the glue injection is completed, place the defrosting component in a normal temperature environment and let it stand for a period of time (the first duration) so that the sealant cures to form a firm sealing layer, ensuring the stability and tightness of the connection.

[0068] In order to more clearly understand the above-mentioned objects, features and advantages of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0069] In the following description, many specific details are set forth in order to fully understand the present application. However, the embodiments of the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present application is not limited to the limitations of the specific embodiments disclosed below.

[0070] Next, refer to Figures 1 to 12 to describe some embodiments of the present invention.

[0071] As shown in Figure 1 and Figure 2As shown in the figure, this embodiment provides a defrosting component 100, which includes a first tube body 102, a heating element 104, a connecting wire 106 and a seal 108. Among them, the inside of the first tube body 102 is hollow to form a heating cavity 1022 for accommodating the heating element 104. The first tube body 102 can prevent damage to the heating element 104 from the external environment (such as moisture, dust, mechanical shock, etc.). At the same time, by providing an assembly port 1024 at at least one end of the first tube body 102, the inside can be sealed in cooperation with the seal 108 under the action of the assembly port 1024.

[0072] Among them, by arranging the heating element 104 in the heating cavity 1022, using the structural characteristics of graphene, its shape is adapted to the tubular structure of the first tube body 102, and a three-dimensional tubular structure is formed on the basis of the two-dimensional structure of graphene, further enhancing the heat conduction performance. Among them, the heating element 104 is fixed in the heating cavity 1022 of the first tube body 102, and one end is connected to the wire through a connection terminal 1042 to ensure that current can smoothly pass through the heating element 104 to generate heat. Due to the high thermal conductivity of the graphene material, it can quickly heat up and transfer heat through both radiation and convection. Since graphene has the characteristic of low latent heat, it is more helpful to quickly cool down after stopping heating, reducing the temperature rise and energy consumption during the defrosting process.

[0073] It should be added that the connecting wire 106 is used to connect the power supply to the connection terminal 1042 of the heating element 104 to ensure that current can reach the heating body smoothly. One end of the connecting wire 106 is connected to the connection terminal 1042 of the heating element 104, and the other end passes through the second hole section 1084 of the seal 108 and is connected to an external power supply or control system.

[0074] It should be emphasized that in this solution, as Figure 4 shown, by providing a seal 108 and arranging two connecting holes inside, namely a first hole section 1082 and a second hole section 1084 that are connected and communicate with each other. Among them, the first hole section 1082 is used to insert the first tube body 102, and the second hole section 1084 is used for the connecting wire 106 or the connection terminal 1042 to pass through. Under the action of the seal 108, it can effectively prevent external water vapor from entering the inside of the first tube body 102, ensure that the electrical connection parts of the heating element 104 and the connecting wire 106 remain dry, and prevent short circuits or damage. At the same time, the self-structure of the seal 108 can provide a certain amount of mechanical support and protection to prevent damage to the wire and terminal during the installation process.

[0075] Furthermore, by injecting glue into the second hole section 1084 of the seal 108, that is, filling as Figure 12The sealant 116 shown can effectively seal the partial gaps where the connection terminal 1042 and the connection wire 106 extend in the second hole section 1084. At the same time, it can also insulate the live connection terminal 1042 and the connection wire 106, thereby achieving double-layer insulation sealing and improving the sealing and insulation effects.

[0076] Specifically, the material of the first tube body 102 is usually quartz glass to provide excellent light transmittance and high and low temperature resistance characteristics. Through the selection of heat-resistant and cold-resistant materials, the stability of the heater under extreme conditions is ensured.

[0077] In some embodiments, optionally, as Figure 7 and Figure 9 shown, the structure of the seal 108 includes a shaft shoulder 1092, a first connection part 1094, and a second connection part 1096. Among them, the shaft shoulder 1092 is the middle part of the seal 108 for connecting the first connection part 1094 and the second connection part 1096. The shaft shoulder 1092, the first connection part 1094, and the second connection part 1096 are of an integral structure. The shaft shoulder 1092, as a relatively wide part of the seal 108, provides enhanced mechanical strength through its larger contact area, helping the seal 108 to maintain its shape and position when subjected to external forces (such as mechanical stresses during installation or operation).

[0078] On this basis, the first connection part 1094 is one end part of the seal 108 and is provided with a first hole section 1082 for connecting the assembly port 1024 of the first tube body 102. The first tube body 102 is inserted into the first hole section 1082 to achieve a sealed connection. It can be understood that under the action of the first connection part 1094, the first tube body 102 can be firmly fixed in the seal 108 to prevent external water vapor or impurities from entering the heating cavity 1022. The second connection part 1096 is located at the other end of the seal 108 and is provided with a second hole section 1084. The second hole section 1084 not only penetrates the second connection part 1096 but also extends into the shaft shoulder 1092 and part of the first connection part 1094. The second connection part 1096 is mainly responsible for leading out the connection wire 106 or the terminal from the seal 108 while maintaining the sealing effect. Since the extension of the second hole section 1084 covers the first connection part 1094, the shaft shoulder 1092, and the second connection part 1096, the tightness of the entire path when the wire passes through is ensured, thereby preventing water vapor from entering.

[0079] The first connecting part 1094 and the second connecting part 1096 are respectively located at both ends of the seal 108, connected by the shaft shoulder 1092, and each undertakes the key tasks of sealing and connection. The first hole section 1082 and the second hole section 1084 are respectively located in the first connecting part 1094 and the second connecting part 1096, and are penetrated by the shaft shoulder 1092 to ensure the airtightness and watertightness of the entire seal 108 during connection.

[0080] In some embodiments, optionally, the size of the shaft shoulder 1092 is relatively large, and the sizes of the first connecting part 1094 and the second connecting part 1096 are both smaller than that of the shaft shoulder 1092. Specifically, the cross-sectional area of the second connecting part 1096 is smaller than the cross-sectional area of the shaft shoulder 1092, and the cross-sectional area of the first connecting part 1094 is smaller than the cross-sectional area of the shaft shoulder 1092. By defining the relatively large shaft shoulder 1092, during the installation process, the assembly safety can be improved. Since the first pipe body 102 is inserted into the first hole section 1082 of the first connecting part 1094, the pipe diameter of the first pipe body 102 must be smaller than the size of the shaft shoulder 1092. Therefore, under the action of the shaft shoulder 1092, the possibility of direct collision between the first pipe body 102 and the external structure can be reduced, and the shaft shoulder 1092 plays a certain protective role.

[0081] In some embodiments, optionally, as Figure 5 shown, the second connecting part 1096 is designed to be cuboid-shaped, which can make the wall surface where the glue injection port 1102 is located a plane, making the glue injection operation more convenient. At the same time, when the second connecting part 1096 is cuboid-shaped, the entire seal 108 is not a complete rotating body. During assembly, it is easier for manual or machine to grip, and it is also easy to distinguish the posture of the seal 108, so as to improve the installation efficiency. It should be noted that a glue injection port 1102 communicating with the second hole section 1084 is provided on the side wall of the second connecting part 1096, allowing glue to be injected into the first pipe body 102 and the seal 108 through the glue injection port 1102 to achieve sealing after assembly.

[0082] It can be understood that the glue will fill the gap between the second connecting part 1096 and the wire, further enhancing the sealing performance and preventing water vapor from infiltrating. Further, the injected glue (such as silicone glue) can form a waterproof barrier after curing, ensuring that the electrical connection part of the connecting wire 106 remains dry and avoiding short circuits or other electrical faults.

[0083] The setting of the glue injection port 1102 can effectively fill the gap during the assembly process, enhance the waterproof performance, and ensure the reliability of the heating element 104 and the connecting wire 106 in humid and extreme temperature environments.

[0084] In some embodiments, optionally, as Figure 5 and Figure 6As shown, a glue injection port 1102 and a positioning protrusion 1104 are provided on the same side wall of the second connecting portion 1096. It can be understood that the positioning protrusion 1104 protrudes from the surface of the side wall of the second connecting portion 1096 and is usually designed as a small protruding part, located on the side wall of the second connecting portion 1096 and adjacent to the glue injection port 1102.

[0085] It can be understood that as Figure 10 shown, the main function of the positioning protrusion 1104 is to help determine the relative circumferential position after the seal 108 is assembled with the first pipe body 102 during the assembly process. The positioning protrusion 1104 can be used as a comparison reference point during installation. By setting it on the same side wall as the glue injection port 1102, since the second connecting portion 1096 is in the shape of a cuboid, the circumferential positions of the positioning protrusion 1104 and the glue injection port 1102 on the second connecting portion 1096 are approximately the same. The positioning protrusion 1104 can be designed to be at the uppermost part of the entire seal 108. During installation, only by adjusting the easily distinguishable structure of the positioning protrusion 1104 above the gravity direction can it be more convenient to align, which can ensure that the seal 108 maintains the correct position during installation and avoid seal failure caused by misalignment.

[0086] The design of the positioning protrusion 1104 ensures that during the assembly process, the second connecting portion 1096 can accurately dock with other components, reducing seal problems caused by poor docking.

[0087] In some embodiments, optionally, as Figure 8 shown, a sealing thread 112 is provided on the inner wall of the first hole section 1082. When the first pipe body 102 is assembled, the sealing thread 112 can form a closer contact surface, reducing the penetration of water vapor or air, significantly improving the sealing performance, and protecting the internal heating element 104 and connecting wire 106.

[0088] In some embodiments, optionally, the second pipe body 114 is an independent tubular structure provided at one end of the first pipe body 102. The internal space of the second pipe body 114 is used to accommodate the connecting wire 106 and the connecting terminal 1042. Specifically, the second pipe body 114 provides space for the connection between the connecting wire 106 and the connecting terminal 1042, and also provides physical protection to prevent the influence of the external environment (such as moisture, dust, mechanical shock, etc.) on the electrical connection.

[0089] It should be emphasized that in this solution, the connecting wire 106 and the connecting terminal 1042 are connected inside the second pipe body 114. Placing the connection position inside the second pipe body 114 can effectively prevent the influence of external factors (such as water vapor, dust) on the electrical connection and reduce the risk of short circuit or failure.

[0090] One end of the connecting wire 106 extends out of the second tube body 114, facilitating connection to an external power supply or control system, enabling an operator to quickly make an electrical connection.

[0091] In some embodiments, optionally, as Figure 2 and Figure 3 shown, a heat shrink sealing tube 1142 is disposed outside the second tube body 114 and the connecting wire 106, which will shrink when heated, thereby tightly wrapping around the second tube body 114 and the connecting wire 106 to form an effective sealing layer to prevent the infiltration of moisture, dust, and other external contaminants.

[0092] It can be understood that the heat shrink sealing tube 1142 is a tubular material with heat shrink properties, usually made of polyolefin or other thermoplastic materials.

[0093] In some embodiments, optionally, the heating element is in the shape of a sheet, specifically a graphene heating sheet, whose axial dimension is much larger than the thickness dimension of the vertical sheet, so that there will be greater radiant energy in the radial direction, facilitating the expansion of the defrosting area, being able to transfer heat more effectively, quickly melting the frost layer, shortening the defrosting time, and improving the overall defrosting efficiency.

[0094] In some embodiments, optionally, the inside of the first tube body 102 is evacuated, which can effectively reduce heat loss during heat transfer, improve the heating efficiency. At the same time, since the inside of the first tube body 102 is in a vacuum state, to a certain extent, it can extend the service life of the heating element located inside and slow down the oxidation of the first tube body 102.

[0095] In some embodiments, optionally, the ratio of the axial dimension to the radial dimension of the first tube body 102 is limited to be not less than 15. The first tube body 102 is a relatively slender structure. The slender structure can make the heat more evenly distributed in the tube body, enhance the heat conduction efficiency, and ensure that the heat generated by the heating element 104 can be effectively transferred to the surrounding frost layer. Among them, the axial dimension of the first tube body 102 is much larger than the radial dimension, and there will be greater radiant energy in the radial direction, facilitating the expansion of the defrosting area, being able to transfer heat more effectively, quickly melting the frost layer, shortening the defrosting time, and improving the overall defrosting efficiency.

[0096] As Figure 11 shown, an embodiment of the second aspect of the present application provides a refrigeration device 200, including an evaporator 202 and a defrosting assembly 100. The defrosting assembly 100 is disposed on one side of the evaporator 202. The evaporator 202 is responsible for absorbing the heat of the surrounding environment, causing the refrigerant to change into a gas during evaporation, thereby achieving a refrigeration effect. The defrosting assembly 100 can quickly melt the frost layer on the surface of the evaporator 202 through the efficient heating of the heating element 104, ensuring that the evaporator 202 maintains good heat exchange efficiency during operation.

[0097] Since the refrigeration device 200 includes any one of the defrosting components 100 described above, it has the beneficial effects of any one of the defrosting components 100, which will not be elaborated here.

[0098] Among them, the refrigeration device 200 includes, but is not limited to, refrigerators, freezers and other devices with refrigeration functions that will frost during operation.

[0099] Furthermore, the number of the defrosting components 100 is one, and the defrosting component 100 is located below the evaporator 202.

[0100] By selecting one defrosting component 100 and placing the defrosting component 100 below the evaporator 202, the defrosting component 100 located below the evaporator 202 can more effectively use the ways of heat radiation and convection to transfer heat to the evaporator 202 and quickly melt the frost layer.

[0101] Even further, insert the first tube body 102 into the first hole section 1082 of the seal 108, and pass the connecting wire 106 through the seal 108; when the first tube body 102 moves to the glue injection position, inject sealant through the glue injection port 1102 of the seal 108 until the sealant overflows from the first hole section 1082 and / or the second hole section 1084; leave the defrosting component 100 after glue injection standing at room temperature for the first period of time; wherein, the glue injection position is the position where one end of the first tube body 102 abuts against the axis of the first hole section 1082.

[0102] This solution mainly provides a sealing method to realize the assembly and glue injection of the defrosting component 100. Specifically, insert the end of the first tube body 102 into the first hole section 1082 of the seal 108 to ensure a preliminary connection between the two. Through the insertion, the connection between the first tube body 102 and the seal 108 begins to form, laying a foundation for subsequent sealing and protection. The insertion operation ensures the correct position of the first tube body 102 in the seal 108, providing space for subsequent glue injection and the passing of the connecting wire 106.

[0103] Then pass one end of the connecting wire 106 through the second hole section 1084 of the seal 108. By passing the connecting wire 106 through, prepare for the connection with an external power supply or control system to ensure the smooth progress of the electrical connection. Among them, when passing the wire, the design ensures that the sealing performance of the seal 108 is not affected and prevents water vapor from infiltrating.

[0104] Move the first tube body 102 to the glue injection position, that is, the position where one end of the first tube body 102 abuts against the axial direction of the first hole section 1082, and then inject sealant through the glue injection port 1102. Inject the sealant to fill the gap between the first hole section 1082 and the first tube body 102, forming a tighter seal to prevent water vapor from seeping in. The injected sealant forms a waterproof barrier after curing to ensure the electrical safety of the connection.

[0105] Continue to inject the sealant until the glue overflows from the first hole section 1082 and / or the second hole section 1084, indicating that the sealant has fully filled all the gaps, ensuring that there are no omissions and enhancing the sealing effect.

[0106] After the glue injection is completed, place the defrosting component 100 in a normal temperature environment and let it stand for a period of time (the first duration) so that the sealant cures to form a solid sealing layer, ensuring the stability and tightness of the connection.

[0107] In a specific embodiment, a graphene heating tube (i.e., the defrosting component 100) is defined. The heating tube is composed of a graphene heating sheet (i.e., the heating element 104), a rubber plug (i.e., the sealing element 108), a metal wire (i.e., the connecting wire 106), a glass conduit (i.e., the second tube body 114), a heat shrinkable tube (i.e., the heat shrinkable sealing tube), a quartz glass tube (i.e., the first tube body 102), and a metal terminal (i.e., the connecting terminal 1042).

[0108] The horizontal dimension of the graphene heating tube is much larger than the vertical dimension, so there is a great deal of radiant heat in the vertical direction. When the graphene heating tube is placed in the middle of the evaporator, it can transfer heat by means of thermal radiation and quickly melt the frost within the height range of three fins around the graphene heating tube. Since the water melted from the frost will directly drip onto the graphene heating tube, there are requirements for the graphene heating tube to be resistant to thermal shock and waterproof. In this design, the outer shell of the heating tube is made of a quartz glass tube. This type of glass tube not only meets the light transmittance requirements but also remains stable in an extreme thermal cycling environment. Glass conduits (i.e., the second tube bodies) are provided at both ends of the quartz glass tube. The glass conduits wrap the lead-out ends of the metal terminals. The metal wire is connected to the lead-out ends of the metal terminals inside the glass conduits, and finally, a heat shrinkable tube is used to seal the metal wire and the glass conduits, thus achieving a good insulation effect. Rubber plugs (i.e., the sealing elements) are used to seal both ends of the quartz glass tube. The material of the rubber plugs is silicone rubber. The silicone rubber has a relatively high strength. It can not only support the graphene heating tube but also effectively protect the insulation structures at both ends of the heater, avoiding the phenomenon of insulation layer scratching during installation. In addition, the silicone rubber has good elasticity. Using silicone rubber to block the glass tube can improve the mechanical strength of the glass tube and avoid damage to the glass tube and the graphene heating sheet caused by dropping impact.

[0109] There are three openings in total on the rubber stopper, namely the glass tube socket (i.e., the first hole section), the wire socket (i.e., the second hole section), and the glue injection port. The glass tube socket is provided with threads (i.e., sealing threads), so that the rubber seal head can be better sealed with the glass tube. When installing the rubber head, the heating tube wire is inserted from the glass tube socket and exits from the wire socket. When the glass tube reaches the bottom of the rubber stopper, insert the glue injection tube from the glue injection port and start injecting glue. When the glue overflows from the glass tube socket and the wire socket, it means that the glue is full. After the glue injection is completed, the heating tube needs to be left standing at room temperature for 24 hours. The glue used in this solution is silicone glue. This type of glue has good fluidity, good waterproof performance after solidification, good adhesion to glass and rubber, and can still maintain good stability under extreme high or low temperature impacts. After the silicone glue solidifies, it fills the gap between the glass tube and the rubber stopper, effectively preventing water from seeping into the inside of the rubber stopper, and further improving the waterproof performance of the graphene heating tube.

[0110] Compared with the related technologies, currently, steel tube heaters mainly rely on heat convection. When defrosting, a large amount of hot air needs to be heated. The hot air convects into the cabin, resulting in a temperature rise. In addition, the latent heat of steel tube heaters is high, and heat will still be continuously radiated after the defrosting stops. When applied to a refrigerator, the temperature of the drip pan in the refrigerator will still rise significantly. Currently, graphene heating tubes have two heat transfer methods, convection and radiation, which reduce the heat transfer to the air and the temperature rise caused by the entry of hot air into the cabin. In addition, the graphene tube has low latent heat, and the temperature of the graphene tube drops quickly after defrosting, and the temperature rise of the drip pan is low. Although there are some glass tube heaters on the market, they still use metal heating wires, and the latent heat of the metal heating wires is still relatively high, and the waterproof solution is not perfect. Compared with these metal wire glass heating tubes, this solution adopts a silicone rubber and silicone glue sealing solution, with better waterproof performance and is more suitable for the humid, extremely high or low temperature environment of the refrigerator.
