Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of refrigeration equipment, in particular to a heat exchanger and refrigeration equipment. Background Art
[0002] Currently, in related technologies, refrigeration equipment operates through a refrigeration cycle in the evaporator piping and defrosting with an electric heater. An electric heater is installed beneath the evaporator to defrost the evaporator. When the electric heater defrosts the evaporator, heat is transferred from the bottom to the top of the evaporator. Areas closer to the heater defrost faster, while areas farther from the heater defrost slower. This results in uneven heating across the evaporator, impacting defrosting efficiency. Utility Model Content
[0003] The utility model aims to solve at least one of the technical problems existing in the prior art or related technologies.
[0004] To this end, a first aspect of the present invention provides a heat exchanger.
[0005] A second aspect of the present invention provides a refrigeration device.
[0006] In view of this, the first aspect of the present invention provides a heat exchanger comprising a tube assembly and a heating element. The tube assembly is provided with a first channel and a second channel, the first channel being for passing a refrigerant, and the second channel being arranged along the first channel. The heating element is disposed within the second channel, extending from one end of the second channel to the other end of the second channel, so that heat generated by the heating element can be transferred to the tube assembly.
[0007] The heat exchanger defined in the present application includes a tube assembly and a heating component. The tube assembly is provided with a first channel and a second channel. The first channel is used for circulating refrigerant. When the heat exchanger is in operation, there is a temperature difference between the refrigerant circulating in the first channel and the outside air, thereby causing frost to form on the surface of the first channel. The second channel is used to set the heating component. The second channel is arranged along the first channel, and one end of the second channel extends to the other end of the second channel. During defrosting, the heat generated by the heating component can be transferred to the tube assembly, and the heat is transferred to the first channel through the second channel, so that the tube wall of the first channel is heated evenly, avoiding the situation where the defrosting speed is fast in the area closer to the heating component and slow in the area farther from the heating component. At the same time, the second channel is used to set the heating component. The second channel is arranged along the first channel, and one end of the second channel extends to the other end of the second channel. During defrosting, the heat generated by the heating component can be transferred to the tube assembly, and the heat is transferred to the first channel through the second channel, thereby causing the frost layer in the first channel to melt synchronously with the heat conduction of the heating component, shortening the defrosting time and accelerating the defrosting speed. At the same time, the second channel is used to set up a heating component, and the second channel is arranged along the first channel. During defrosting, the heat generated by the heating component can be transferred to the tube assembly, and the heat is transferred to the first channel through the second channel, so that the frost layer in the first channel melts synchronously, reducing the heat loss generated by the heating component, and making the heat utilization rate high, thereby accelerating the defrosting speed of the heat exchanger, improving the time efficiency, and increasing the defrosting efficiency of the heat exchanger.
[0008] The heat exchanger defined in the present application arranges a heating component along the first channel. During defrosting, the heating component is transferred to the first channel, ensuring that the frost layer in all areas of the heat exchanger is melted synchronously with the conduction of heat from the heating component, thereby shortening the defrosting time of the heat exchanger and reducing the energy consumption of the heat exchanger.
[0009] The heat exchanger defined in this application replaces the design structure of placing a heating component below the evaporator by arranging the heating component along the first channel. This avoids the need for independent placement of the first channel and the heating component, simplifies the internal structure of the heat exchanger, streamlines the manufacturing process, and thereby improves heat exchanger production efficiency and reduces production costs. Furthermore, by arranging the heating component along the first channel, an integrated heat exchanger design is achieved, simplifying the internal structure of the heat exchanger, reducing the internal space occupied by the heat exchanger, increasing the operating space for personnel during subsequent maintenance, and thus improving the convenience of subsequent maintenance.
[0010] The heat exchanger defined in the present application replaces the design structure of setting the heating component at the bottom of the evaporator by arranging the heating component along the first channel, avoiding the independent arrangement of the first channel and the heating component, simplifying the internal structure of the heat exchanger, and making the internal space of the heat exchanger smaller, thereby increasing the freezing space of the refrigeration equipment and increasing the user's usable space.
[0011] The heat exchanger defined in the present application arranges a heating component along the first channel. When the heat exchanger is working, the air passes through the dual pipes of the first channel and the second channel, and the air circulates around the dual pipes, thereby increasing the air turbulence area of the heat exchanger, and increasing the energy exchange area between the heat exchanger and the air, thereby improving the cooling effect of the heat exchanger and enhancing the cooling capacity of the heat exchanger.
[0012] The heat exchanger defined in the present application arranges a heating component along the first channel. Since the frost layer on the surface of the first channel can be removed by the heating component in a short time, the electrical energy of the heating component during defrosting is reduced. While reducing the energy consumption of defrosting, the risk of refrigerant explosion caused by excessive wall temperature of the heat exchanger is avoided, thereby improving the safety of defrosting.
[0013] In addition, the heat exchanger in the above technical solution provided by the present invention may also have the following additional technical features:
[0014] In some technical solutions of the present invention, optionally, the heat exchanger further includes a heat-conducting component, which is disposed in the second channel, covers the heating component, and contacts the inner wall of the second channel.
[0015] In this technical solution, the heat exchanger also includes a heat-conducting component, which is arranged in the second channel and is used to transfer the heat of the heating component to the inner wall of the second channel. Since the second channel is arranged along the first channel, the tube wall of the second channel is heated evenly, thereby playing a defrosting role.
[0016] In some technical solutions of the present invention, optionally, the heat-conducting component is a magnesium oxide filler, and the heating component is an electric heating wire.
[0017] In this technical solution, magnesium oxide, with its excellent thermal conductivity and insulation properties, is used as a heat-conducting component, tightly packed within the second channel to achieve both thermal conductivity and insulation from the tube body. The electric heating wire, acting as the heating element, achieves uniform heat transfer through the magnesium oxide filler. During the heat exchanger defrosting process, the surface temperature of the heating element rises rapidly, quickly removing the frost layer on the surface of the first channel and improving the heat exchanger's defrosting efficiency. Furthermore, the surface of the heating element is non-conductive, ensuring user safety.
[0018] In some technical solutions of the present invention, the tube assembly optionally includes a first tube body and a second tube body. The first tube body is provided with a first channel; the second tube body is arranged in parallel with the first tube body, the second tube body extends from one end of the first tube body to the other end of the first tube body, and the outer wall of the second tube body is connected to the outer wall of the first tube body.
[0019] In this technical solution, the tube assembly includes a first tube body and a second tube body. The first tube body is provided with a first channel. The second tube body is arranged in parallel with the first tube body and connected to the outer wall of the first tube body through the outer wall of the second tube body. When the first channel is heated, the outer wall of the second tube body is quickly heated, quickly removing the frost layer on the outer wall of the second tube body, thereby improving the defrosting efficiency of the heat exchanger. At the same time, when the heat exchanger is cooling, the air passing through the dual pipes of the first and second tube bodies increases the air turbulence area of the heat exchanger, thereby increasing the heat exchange rate on the air side of the heat exchanger and improving the cooling capacity of the heat exchanger.
[0020] In some technical solutions of the present invention, optionally, the second tube body is welded to the first tube body; or the tube assembly further includes a connector, and the first tube body is connected to the second tube body via the connector.
[0021] In this technical solution, the outer wall of the first tube body is connected to the outer wall of the second tube body by welding or connecting parts, so that when the second channel is heated, the outer wall of the first tube body is quickly heated, and the frost layer on the outer wall of the first tube body is quickly removed, thereby improving the defrosting efficiency of the heat exchanger.
[0022] In some technical solutions of the present invention, optionally, the tube assembly includes a third tube body, and the first channel and the second channel are arranged in parallel in the third tube body.
[0023] In this technical solution, the first channel and the second channel are arranged side by side in the third tube body. During defrosting, the heat generated by the heating component can be transferred to the first channel, so that the heat of the second channel continuously passes through the entire first channel during defrosting, thereby making the tube wall of the first channel heated evenly, shortening the time required for defrosting, and improving the defrosting efficiency of the heat exchanger.
[0024] In some technical solutions of the present invention, optionally, the tube assembly also includes a first partition, which is arranged in the third tube body and extends from one end of the third tube body to the other end of the third tube body. The first partition divides the internal space of the third tube body into a first channel and a second channel.
[0025] In this technical solution, a first partition divides the third tube into two independent spaces: a first channel and a second channel. Specifically, by arranging the heating component along the first channel, the heat exchanger achieves an integrated design. This avoids the need for separate configurations of the first channel and the heating component, simplifies the internal structure of the heat exchanger, and reduces internal space, increasing the operating space for maintenance personnel and improving the convenience of subsequent maintenance.
[0026] Specifically, the heat exchanger arranges the heating component along the first channel, thereby avoiding the independent arrangement of the first channel and the heating component, simplifying the internal structure of the heat exchanger, making the heat exchanger occupy less space, increasing the freezing space, and thereby improving the user's usable space.
[0027] At the same time, the first partition separates the internal space of the third tube body into a first channel and a second channel. During defrosting, the heat in the second channel is transferred to the third tube body, so that the frost layer generated in the first channel is heated evenly, thereby improving the defrosting efficiency of the heat exchanger.
[0028] In some technical solutions of the present invention, optionally, the tube assembly also includes a second partition, and the number of the second partitions is multiple. The multiple second partitions are arranged in parallel in the third tube body, extending from one end of the third tube body to the other end of the third tube body. At least one of the multiple second partitions and the inner wall of the third tube body enclose a first channel, and a second channel is arranged between two adjacent second partitions among the multiple second partitions.
[0029] In this technical solution, the tube assembly also includes a second partition, and there are multiple second partitions, which are arranged in parallel in the third tube body. The second partitions are used to divide the third tube body into multiple independent spaces. A first channel is enclosed by at least one of the second partitions and the inner wall of the third tube body. A second channel is provided between two adjacent second partitions among the multiple second partitions, so that the second channel and the first channel are arranged in parallel. During defrosting, the heat from the second channel continuously passes through the entire first channel, so that the tube wall of the first channel is heated evenly, shortening the time required for defrosting and improving the defrosting efficiency of the heat exchanger.
[0030] Specifically, if there are two second partitions, the third tube body is divided into three parallel independent channels, and a second channel is provided between two adjacent second partitions in the second partition, then the middle channel is the second channel, and the first channels are on both sides of the second channel. The heat in the second channel is transferred to the third tube body, so that the frost layer on the surface of the first channel melts quickly, shortening the time required for defrosting and improving the defrosting efficiency of the heat exchanger. At the same time, the third channel is an integrated forming design, which avoids the independent arrangement of the first channel and the heating component, simplifies the internal structure of the heat exchanger, and makes the internal space of the heat exchanger smaller, increases the operating space for the staff during the later maintenance, and thus improves the convenience of the later maintenance. Alternatively, the third channel is an integrated forming design, which simplifies the internal structure of the heat exchanger, makes the internal space of the heat exchanger smaller, increases the freezing space, and thus improves the user's use space.
[0031] In some technical solutions of the present invention, optionally, at least one second partition plate among the plurality of second partition plates is connected to the inner wall of the third tube body.
[0032] In this technical solution, at least one of the multiple second partitions is connected to the inner wall of the third tube body, so that the second partition is connected and in contact with the inner wall of the third tube body. When the second channel generates heat, the heat is transferred to the inner wall of the third tube body through the second partition, so that the third tube body is quickly heated, and the surface frost layer is quickly removed, thereby improving the defrosting efficiency of the heat exchanger.
[0033] In some technical solutions of the present invention, optionally, the tube assembly also includes a fourth tube body, which is arranged in the third tube body and extends from one end of the third tube body to the other end of the third tube body. A first channel is provided between the inner wall of the third tube body and the outer wall of the fourth tube body, and a second channel is provided in the fourth tube body.
[0034] In this technical solution, the tube assembly also includes a fourth tube body, which is arranged in the third tube body. A first channel is arranged between the inner wall of the third tube body and the outer wall of the fourth tube body. A second channel is arranged in the fourth tube body, that is, the first channel is wrapped around the outer periphery of the second channel. When defrosting, the second channel transfers heat to the surface of the first channel, so that the frost layer on the surface of the first channel melts quickly, thereby improving the defrosting efficiency of the heat exchanger.
[0035] Furthermore, the fourth tube body is disposed within the third tube body, thereby avoiding the need for the first channel and the heating component to be disposed independently of each other, simplifying the internal structure of the heat exchanger, reducing the space occupied by the heat exchanger, and increasing the operating space for staff during subsequent maintenance, thereby improving the convenience of subsequent maintenance. Alternatively, the fourth tube body is disposed within the third tube body, simplifying the internal structure of the heat exchanger, reducing the space occupied by the heat exchanger, increasing the freezing space, and thereby increasing the space available to users.
[0036] In some technical solutions of the present invention, optionally, the tube assembly further includes a heat conducting plate, which is disposed in the first channel, with one side of the heat conducting plate connected to the third tube body and the other side connected to the fourth tube body.
[0037] In this technical solution, the tube assembly also includes a heat conducting plate, which connects the third tube body and the fourth tube body through the heat conducting plate. When the heating component is working, the electric heating wire inside the fourth tube body emits heat energy, and the heat conducting component transfers the heat to the fourth tube body. The heat of the fourth tube body is transferred to the third tube body through the heat conducting plate, so that the third tube body is heated evenly, and the frost layer on the surface of the third tube body is quickly melted, thereby accelerating the speed of heat transfer and improving the defrosting efficiency of the heat exchanger.
[0038] In some technical solutions of the present invention, optionally, the tube assembly also includes a third partition, and the number of the third partitions is multiple. The multiple third partitions are arranged in parallel in the third tube body, extending from one end of the third tube body to the other end of the third tube body. The multiple third partitions divide the internal space of the third tube body into multiple channels, at least one channel among the multiple channels is a second channel, and the channels other than the second channel among the multiple channels are first channels.
[0039] In this technical solution, the tube assembly further includes a plurality of third baffles, which divide the interior space of the third tube into a plurality of channels. At least one of the plurality of channels is a second channel, and at least one of the plurality of channels is a second channel. Heat from the second channel is transferred to the first channel, melting frost on the surface of the first channel.
[0040] In some technical solutions of the present invention, optionally, the cross-section of the third tube is rectangular, circular, pentagonal or hexagonal.
[0041] In this technical solution, the cross-section of the third tube body is rectangular, circular, pentagonal or hexagonal, and heat is transferred to the tube assembly through the tube body wall, so that the tube wall of the first channel is heated evenly, shortening the defrosting time and improving the defrosting efficiency of the heat exchanger.
[0042] In some technical solutions of the present invention, optionally, the cross-sectional area of the first channel is larger than the cross-sectional area of the second channel.
[0043] In this technical solution, the cross-sectional area of the first channel is larger than that of the second channel, that is, the cross-sectional area of the refrigerant medium flow is larger than the cross-sectional area of the heating component, so as to avoid excessive heat in the second channel and interference with the energy replacement effect of the first channel. The heat in the second channel is sufficient to melt the frost layer on the surface of the first channel, so as to avoid hot air entering the refrigeration chamber due to the high heat in the second channel, which is not conducive to food storage.
[0044] In some technical solutions of the present invention, optionally, the heat exchanger further includes fins, and the number of the fins is multiple, and the multiple fins are sleeved on the tube assembly and arranged in parallel from one end of the tube assembly to the other end of the tube assembly.
[0045] In this technical solution, the heat exchanger also includes fins, and multiple fins are arranged in parallel along the tube assembly. Through the arrangement of the fins, when the fluid flows through the fin surface, the heat exchange between the fluid and the heat exchange surface is more sufficient due to the increase in surface area, thereby improving the heat exchange efficiency of the heat exchanger and thus enhancing the user experience.

Therefore, the refrigeration device has all the beneficial effects of the heat exchanger as described in any one of the above technical solutions.

DETAILED DESCRIPTION
[0061] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.
[0062] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.
[0063] Refer to the following Figures 1 to 10 The heat exchanger 100 and the refrigeration equipment according to some embodiments of the present invention are described.
[0064] In the embodiment of the present utility model, Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, a heat exchanger 100 is provided, comprising a tube assembly 110 and a heating component 140. Tube assembly 110 is provided with a first channel 112 and a second channel 114. First channel 112 is used to pass refrigerant, and second channel 114 is arranged along first channel 112. Heating component 140 is disposed within second channel 114, extending from one end of second channel 114 to the other end of second channel 114. Heat generated by heating component 140 can be transferred to tube assembly 110.
[0065] The heat exchanger 100 defined in the present application includes a tube assembly 110 and a heating component 140. The tube assembly 110 is provided with a first channel 112 and a second channel 114. The first channel 112 is used for circulating refrigerant. When the heat exchanger 100 is in operation, there is a temperature difference between the refrigerant circulating in the first channel 112 and the outside air, thereby causing frost to form on the surface of the first channel 112. The second channel 114 is used to arrange the heating component 140. The second channel 114 is arranged along the first channel 112, and one end of the second channel 114 extends to the other end of the second channel 114. During defrosting, the heat generated by the heating component 140 can be transferred to the tube assembly 110. The heat is then transferred to the first channel 112 through the second channel 114, so that the tube wall of the first channel 112 is heated evenly, avoiding the situation where the defrosting speed is fast in the area of the first channel 112 closer to the heating component 140 and slow in the area of the first channel 112 farther from the heating component 140. At the same time, the second channel 114 is used to set up the heating component 140. The second channel 114 is arranged along the first channel 112, and one end of the second channel 114 extends to the other end of the second channel 114. During defrosting, the heat generated by the heating component 140 can be transferred to the tube assembly 110, and the heat of the second channel 114 is transferred to the first channel 112, so that the frost layer of the first channel 112 is melted synchronously with the conduction of heat from the heating component 140, shortening the time required for defrosting and avoiding the situation where the defrosting speed is slow in the area of the first channel 112 that is far away from the heating component 140. At the same time, the second channel 114 is used to set up the heating component 140. The second channel 114 is arranged along the first channel 112, and one end of the second channel 114 extends to the other end of the second channel 114. During defrosting, the heat generated by the heating component 140 can be transferred to the tube assembly 110, and the heat of the second channel 114 is transferred to the first channel 112, so that the frost layer of the first channel 112 melts synchronously, so that the heat of the heating component 140 is not wasted, and the heat utilization rate is high, thereby making the heat exchanger 100 defrost quickly and time-efficient, thereby increasing the defrosting efficiency of the heat exchanger 100.
[0066] The heat exchanger 100 defined in the present application arranges the heating component 140 along the first channel 112. During defrosting, the heating component 140 is transferred to the first channel 112, ensuring that the frost layer in all areas of the heat exchanger 100 is melted synchronously with the conduction of heat from the heating component 140, thereby shortening the defrosting time of the heat exchanger 100 and reducing the energy consumption of the heat exchanger 100.
[0067] The heat exchanger 100 defined in the present application arranges the heating component 140 along the first channel 112, replacing the design structure of setting the heating component 140 at the bottom of the evaporator, avoiding the first channel 112 and the heating component 140 being set independently of each other, simplifying the internal structure of the heat exchanger 100, simplifying the manufacturing process, thereby improving the production efficiency of the heat exchanger 100 and reducing production costs.
[0068] The heat exchanger 100 defined in the present application replaces the design structure of setting the heating component 140 at the bottom of the evaporator by arranging the heating component 140 along the first channel 112, avoiding the independent arrangement of the first channel 112 and the heating component 140, realizing the integrated molding design of the heat exchanger 100, simplifying the internal structure of the heat exchanger 100, making the internal space of the heat exchanger 100 smaller, increasing the operating space for the staff for subsequent maintenance, and thereby improving the convenience of subsequent maintenance.
[0069] The heat exchanger 100 defined in the present application arranges the heating component 140 along the first channel 112, replacing the design structure in which the heating component 140 is arranged at the bottom of the evaporator, thereby avoiding the first channel 112 and the heating component 140 being arranged independently of each other, simplifying the internal structure of the heat exchanger 100, and making the internal space of the heat exchanger 100 smaller, thereby increasing the freezing space of the refrigeration equipment and increasing the user's usable space.
[0070] The heat exchanger 100 defined in the present application arranges the heating component 140 along the first channel 112. When the heat exchanger 100 is in operation, the air flows around the dual pipes of the first channel 112 and the second channel 114, thereby increasing the air turbulence area of the heat exchanger 100, thereby increasing the energy exchange area between the heat exchanger 100 and the air, thereby achieving a better cooling effect of the heat exchanger 100 and improving the cooling capacity of the heat exchanger 100.
[0071] The heat exchanger 100 defined in the present application arranges a heating component 140 along the first channel 112. Since the frost layer on the surface of the first channel 112 can be removed in a short time by the heating component 140, the electric energy required by the heating component 140 during defrosting is reduced. While reducing the energy consumption of defrosting, the risk of refrigerant explosion caused by excessive wall temperature of the heat exchanger 100 is avoided, thereby improving the safety of defrosting.
[0072] In addition, the heat exchanger 100 in the above technical solution provided in the embodiment of the present invention may also have the following additional technical features:
[0073] In the embodiment of the present utility model, Figure 3 and Figure 4 As shown, optionally, the heat exchanger 100 further includes a heat conducting component 150 , which is disposed in the second channel 114 , covers the heating component 140 , and contacts the inner wall of the second channel 114 .
[0074] In this embodiment, the heat exchanger 100 further includes a heat-conducting component 150, which is disposed in the second channel 114 and is used to transfer the heat of the heating component 140 to the inner wall of the second channel 114. Since the second channel 114 is arranged along the first channel 112, the tube wall of the second channel 114 is heated evenly, thereby achieving a defrosting effect.
[0075] In the embodiment of the present utility model, Figure 1 、 Figure 2 and Figure 10 As shown, optionally, the heat-conducting component 150 is a magnesium oxide filler, and the heating component 140 is an electric heating wire.
[0076] In this embodiment, magnesium oxide has excellent thermal conductivity and insulation properties. A magnesium oxide filler is used as a heat conducting component 150 and tightly packed within the second channel 114, achieving both thermal conductivity and insulation from the tube body. An electric heating wire is used as the heating component 140, and the magnesium oxide filler achieves uniform heat transfer. During the defrosting process of the heat exchanger 100, the surface temperature of the heating component 140 rises rapidly, quickly removing the frost layer on the surface of the first channel 112, improving the defrosting efficiency of the heat exchanger 100. Furthermore, the surface of the heating component 140 is non-conductive, ensuring user safety.
[0077] In the embodiment of the present utility model, Figure 1 、 Figure 2 and Figure 3 As shown, optionally, the tube assembly 110 includes a first tube body 116 and a second tube body 118. The first tube body 116 is provided with a first channel 112; the second tube body 118 is arranged in parallel with the first tube body 116, and the second tube body 118 extends from one end of the first tube body 116 to the other end of the first tube body 116, and the outer wall of the second tube body 118 is connected to the outer wall of the first tube body 116.
[0078] In this embodiment, the tube assembly 110 includes a first tube 116 and a second tube 118. The first tube 116 is provided with a first channel 112. The second tube 118 is arranged in parallel with the first tube 116, and the outer wall of the second tube 118 is connected to the outer wall of the first tube 116. When the first channel 112 is heated, the outer wall of the second tube 118 is quickly heated, and the frost layer on the outer wall of the second tube 118 is quickly removed, thereby improving the defrosting efficiency of the heat exchanger 100. At the same time, when the heat exchanger 100 is cooling, the air passes through the dual pipes of the first tube 116 and the second tube 118, which increases the air turbulence area of the heat exchanger 100, thereby increasing the heat exchange amount on the wind side of the heat exchanger 100 and improving the cooling capacity of the heat exchanger 100.
[0079] In the embodiment of the present utility model, Figure 3 and Figure 4As shown, optionally, the second tube body 118 is welded to the first tube body 116 ; or the tube assembly 110 further includes a connector 160 , and the first tube body 116 is connected to the second tube body 118 via the connector 160 .
[0080] In this embodiment, the outer wall of the first tube body 116 is connected to the outer wall of the second tube body 118 by welding or a connector 160, so that when the second channel 114 is heated, the outer wall of the first tube body 116 is quickly heated, and the frost layer on the outer wall of the first tube body 116 is quickly removed, thereby improving the defrosting efficiency of the heat exchanger 100.
[0081] In the embodiment of the present utility model, Figure 5 and Figure 6 As shown, optionally, the tube assembly 110 includes a third tube body 120 , in which a first channel 112 and a second channel 114 are arranged in parallel.
[0082] In this embodiment, the first channel 112 and the second channel 114 are arranged side by side in the third tube body 120. During defrosting, the heat generated by the heating component 140 can be transferred to the first channel 112, so that the heat of the second channel 114 continuously passes through the entire first channel 112 during defrosting, thereby making the tube wall of the first channel 112 evenly heated, shortening the time required for defrosting, and improving the defrosting efficiency of the heat exchanger 100.
[0083] In the embodiment of the present utility model, Figure 5 and Figure 6 As shown, optionally, the tube assembly 110 also includes a first partition 122, which is disposed in the third tube body 120 and extends from one end of the third tube body 120 to the other end of the third tube body 120. The first partition 122 separates the internal space of the third tube body 120 into a first channel 112 and a second channel 114.
[0084] In this embodiment, the third tube 120 is divided into two independent spaces by a first partition 122: a first channel 112 and a second channel 114. Specifically, by arranging the heating component 140 along the first channel 112, the heat exchanger 100 achieves an integrated design. This avoids the need for separate arrangements of the first channel 112 and the heating component 140, simplifies the internal structure of the heat exchanger 100, reduces the internal space occupied by the heat exchanger 100, and increases the operating space for staff during subsequent maintenance, thereby improving the convenience of subsequent maintenance.
[0085] Specifically, the heat exchanger 100 arranges the heating component 140 along the first channel 112, thereby avoiding the independent arrangement of the first channel 112 and the heating component 140, simplifying the internal structure of the heat exchanger 100, making the internal space of the heat exchanger 100 smaller, increasing the freezing space, and thereby improving the user's usage space.
[0086] At the same time, the first partition 122 separates the internal space of the third tube body 120 into a first channel 112 and a second channel 114. During defrosting, the heat in the second channel 114 is transferred to the third tube body 120, so that the frost layer generated by the first channel 112 is evenly heated, thereby improving the defrosting efficiency of the heat exchanger 100.
[0087] In the embodiment of the present utility model, Figure 6 and Figure 9 As shown, optionally, the tube assembly 110 further includes a second partition 124, and the number of the second partitions 124 is multiple, and the multiple second partitions 124 are arranged in parallel in the third tube body 120, extending from one end of the third tube body 120 to the other end of the third tube body 120, and at least one second partition 124 among the multiple second partitions 124 and the inner wall of the third tube body 120 enclose a first channel 112, and a second channel 114 is arranged between two adjacent second partitions 124 among the multiple second partitions 124.
[0088] In this embodiment, the tube assembly 110 also includes a second partition 124, and the number of the second partitions 124 is multiple, which are arranged in parallel in the third tube body 120. The second partitions 124 are used to divide the third tube body 120 into multiple independent spaces. A first channel 112 is enclosed by at least one of the second partitions 124 and the inner wall of the third tube body 120. A second channel 114 is provided between two adjacent second partitions 124 among the multiple second partitions 124, so that the second channel 114 and the first channel 112 are arranged in parallel. During defrosting, the heat of the second channel 114 continuously passes through the entire first channel 112, so that the tube wall of the first channel 112 is heated evenly, shortening the time required for defrosting and improving the defrosting efficiency of the heat exchanger 100.
[0089] Specifically, if there are two second partitions 124, the third tube 120 is divided into three parallel independent channels. A second channel 114 is provided between two adjacent second partitions 124. The middle channel is the second channel 114, and the first channels 112 are located on either side of the second channel 114. Heat within the second channel 114 is transferred to the third tube 120, causing the frost layer on the surface of the first channel 112 to melt quickly, shortening the defrosting time and improving the defrosting efficiency of the heat exchanger 100. Furthermore, the third channel is an integrated design, eliminating the need for separate arrangements of the first channel 112 and the heating element 140. This simplifies the internal structure of the heat exchanger 100, reduces the internal space occupied by the heat exchanger 100, and increases the operating space for staff during subsequent maintenance, thereby improving the convenience of subsequent maintenance. Alternatively, the third channel is an integrated design, simplifying the internal structure of the heat exchanger 100, reducing the internal space occupied by the heat exchanger 100, increasing the freezer space, and thus increasing the user's usable space.
[0090] In the embodiment of the present utility model, Figure 6 and Figure 9 As shown, optionally, at least one second partition plate 124 among the plurality of second partition plates 124 is connected to the inner wall of the third tube body 120 .
[0091] In this embodiment, at least one second partition 124 among the multiple second partitions 124 is connected to the inner wall of the third tube body 120, so that the second partition 124 is connected and in contact with the inner wall of the third tube body 120. When the second channel 114 generates heat, the heat is transferred to the inner wall of the third tube body 120 through the second partition 124, so that the third tube body 120 is quickly heated, and the surface frost layer is quickly removed, thereby improving the defrosting efficiency of the heat exchanger 100.
[0092] In the embodiment of the present utility model, Figure 7 and Figure 8 As shown, optionally, the tube assembly 110 also includes a fourth tube body 126, which is arranged in the third tube body 120 and extends from one end of the third tube body 120 to the other end of the third tube body 120. A first channel 112 is provided between the inner wall of the third tube body 120 and the outer wall of the fourth tube body 126, and a second channel 114 is provided in the fourth tube body 126.
[0093] In this embodiment, the tube assembly 110 also includes a fourth tube body 126, which is arranged in the third tube body 120. A first channel 112 is provided between the inner wall of the third tube body 120 and the outer wall of the fourth tube body 126. A second channel 114 is provided in the fourth tube body 126, that is, the first channel 112 is wrapped around the outer periphery of the second channel 114. When defrosting, the second channel 114 transfers heat to the surface of the first channel 112, so that the frost layer on the surface of the first channel 112 melts quickly, thereby improving the defrosting efficiency of the heat exchanger 100.
[0094] At the same time, the fourth tube 126 is disposed within the third tube 120, thereby avoiding the need for the first channel 112 and the heating element 140 to be independently disposed. This simplifies the internal structure of the heat exchanger 100, reduces the internal space occupied by the heat exchanger 100, and increases the operating space for staff during subsequent maintenance, thereby improving the convenience of subsequent maintenance. Alternatively, the fourth tube 126 is disposed within the third tube 120, simplifying the internal structure of the heat exchanger 100, reducing the internal space occupied by the heat exchanger 100, increasing the freezing space, and thereby improving the user's usable space.
[0095] In the embodiment of the present utility model, Figure 7 and Figure 8 As shown, optionally, the tube assembly 110 further includes a heat conducting plate 128 , which is disposed in the first channel 112 , with one side of the heat conducting plate 128 connected to the third tube body 120 and the other side connected to the fourth tube body 126 .
[0096] In this embodiment, the tube assembly 110 also includes a heat conducting plate 128, which connects the third tube body 120 to the fourth tube body 126. When the heating component 140 is working, the electric heating wire inside the fourth tube body 126 emits heat energy, and the heat conducting component 150 transfers the heat to the fourth tube body 126. The heat of the fourth tube body 126 is transferred to the third tube body 120 through the heat conducting plate 128, so that the third tube body 120 is evenly heated, and the frost layer on the surface of the third tube body 120 is quickly melted, thereby accelerating the speed of heat transfer and improving the defrosting efficiency of the heat exchanger 100.
[0097] In the embodiment of the present utility model, Figure 8 As shown, optionally, the tube assembly 110 also includes a third partition 130, and the number of the third partitions 130 is multiple. The multiple third partitions 130 are arranged in parallel in the third tube body 120, extending from one end of the third tube body 120 to the other end of the third tube body 120. The multiple third partitions 130 divide the internal space of the third tube body 120 into multiple channels 170, at least one channel 170 among the multiple channels 170 is the second channel 114, and the channels 170 other than the second channel 114 among the multiple channels 170 are the first channels 112.
[0098] In this embodiment, the tube assembly 110 further includes a plurality of third baffles 130, which divide the interior space of the third tube body 120 into a plurality of channels 170. At least one of the plurality of channels 170 is the second channel 114, so that heat from the second channel 114 is transferred to the first channel 112, melting the frost on the surface of the first channel 112.
[0099] In the embodiment of the present utility model, Figure 7 and Figure 8 As shown, optionally, the cross section of the third tube body 120 is rectangular, circular, pentagonal or hexagonal.
[0100] In this embodiment, the cross-section of the third tube body 120 is rectangular, circular, pentagonal or hexagonal, and heat is transferred to the tube assembly 110 through the tube body wall, so that the tube wall of the first channel 112 is heated evenly, shortening the defrosting time and improving the defrosting efficiency of the heat exchanger 100.
[0101] In the embodiment of the present utility model, Figure 6 、 Figure 7 and Figure 8 As shown, optionally, the cross-sectional area of the first channel 112 is greater than the cross-sectional area of the second channel 114 .
[0102] In this embodiment, the cross-sectional area of the first channel 112 is larger than the cross-sectional area of the second channel 114, that is, the cross-sectional area of the refrigerant medium flow is larger than the cross-sectional area of the heating component 140, so as to avoid excessive heat in the second channel 114 and interference with the energy replacement effect of the first channel 112. The heat in the second channel 114 is sufficient to melt the frost layer on the surface of the first channel 112, so as to avoid hot air entering the refrigeration chamber due to the high heat in the second channel 114, which is not conducive to food storage.
[0103] In the embodiment of the present utility model, Figure 1 and Figure 2 As shown, optionally, the heat exchanger 100 further includes a plurality of fins 142 , and the plurality of fins 142 are sleeved on the tube assembly 110 and arranged in parallel from one end of the tube assembly 110 to the other end of the tube assembly 110 .
[0104] In this embodiment, the heat exchanger 100 also includes fins 142, and multiple fins 142 are arranged in parallel along the tube assembly 110. Through the arrangement of the fins 142, when the fluid flows through the surface of the fins 142, the heat exchange between the fluid and the heat exchange surface is more sufficient due to the increase in surface area, thereby improving the heat exchange efficiency of the heat exchanger 100 and enhancing the user experience.
