Description

Technical Field

[0001] This utility model relates to the field of clothing processing equipment, and in particular to a heat exchanger and clothing processing equipment. Background Technology

[0002] Commercially available clothing processing equipment, such as dryers, incorporates a heat exchanger structure for heat exchange. The heat exchanger structure includes heat exchange tubes and fins, with the fins being flat. The heat exchange tubes pass through the fin holes of the fins, and contain the heat exchange medium. The heat exchange medium exchanges heat with the outside environment through the heat exchange tubes and fins.

[0003] However, the heat transfer capacity between the heat exchange tubes and fins in the existing heat exchanger structure is poor, resulting in low heat exchange efficiency. In addition, fine lint is usually blown to the surface of the heat exchanger by the airflow in the air duct. The lint entering the heat exchanger will affect the heat exchange effect. Utility Model Content

According to this invention, a flow-turbating element is designed on the heat exchanger body. The flow-turbating element has protrusions that can block lint from entering the heat exchanger, preventing lint from affecting heat exchange. Simultaneously, the protrusions can promote turbulence inside the heat exchanger, increase the heat exchange area, and improve the heat exchange efficiency.

[0005] This utility model also proposes a clothing processing device including the above-mentioned heat exchanger.

[0006] The heat exchanger according to this utility model includes a heat exchanger body, on which fins are formed. The fins are configured as flow-turbing elements, and the surface of the flow-turbing elements has protrusions.

[0007] The heat exchanger of this invention comprises a heat exchanger body and a baffle. The baffle has protrusions that effectively block lint from entering the heat exchanger. Specifically, during operation, lint may enter the heat exchanger with the airflow. When the baffle is inserted into the heat exchanger body, the protrusions prevent the lint from contacting the flat tube. Heat exchange occurs between the airflow and the heat exchanger, while the lint accumulates on the protrusions. In other words, the protrusions act as a barrier, preventing lint from penetrating further into the heat exchanger and thus protecting its operation from lint, improving its heat exchange efficiency. Simultaneously, the protrusions enhance the baffle's turbulence, causing periodic turbulence on its surface, reducing lint deposition and facilitating cleaning. Furthermore, the protrusions promote turbulence within the heat exchanger, increasing its heat exchange area and further enhancing its heat exchange performance.

[0008] According to one embodiment of the present invention, the spoiler is configured as a plurality of spaced-apart components in the thickness direction, and each spoiler has a protrusion formed on at least one side surface in the thickness direction.

[0009] According to one embodiment of the present invention, a through groove is formed on the turbulence member, the end of the through groove is open and adapted to cooperate with the heat exchanger body, and the protruding direction of the protrusion intersects with the extending direction of the through groove to block lint from entering the heat exchanger.

[0010] According to one embodiment of the present invention, the spoiler includes: a spoiler plate, wherein the spoiler plate is configured to be a plurality of such plates stacked in the thickness direction, each of the spoiler plates having a through groove formed thereon, and each of the spoiler plates having a protrusion protruding from at least one side in the thickness direction of the spoiler plate.

[0011] According to one embodiment of the present invention, each of the spoilers has a plurality of through slots spaced apart in the height direction, and the protrusions are configured to be a plurality of protrusions spaced apart in the height direction of the spoiler, with the through slots provided between two adjacent protrusions.

[0012] According to one embodiment of the present invention, each of the protrusions is provided with a non-uniform thickness in the width direction of the spoiler.

[0013] According to one embodiment of the present invention, the protrusion includes a protrusion body, wherein the protrusion body is configured to be a plurality of protrusion bodies spaced apart in the width direction of the spoiler, and the thickness of two adjacent protrusion bodies gradually decreases in the direction of approaching each other.

[0014] According to one embodiment of the present invention, the outer surface of each protrusion in the thickness direction is constructed as an arc-shaped surface or a polygonal surface connected by multiple planes.

[0015] According to one embodiment of the present invention, the distance between two adjacent spoilers is not greater than the thickness of the protrusion.

[0016] According to one embodiment of the present invention, the heat exchanger body includes: a flat tube, wherein the flat tube is constructed as a plurality of tubes stacked in the height direction, and each flat tube is respectively housed in a corresponding through groove.

[0017] According to one embodiment of the present invention, one end of the flat tube is connected to the same-side end of the flat tube on the adjacent side, and the other end of the flat tube is connected to the other end of the flat tube on the adjacent side.

[0018] The following is a brief description of the garment processing equipment according to this utility model.

[0019] The clothing processing device according to this utility model includes the heat exchanger in the above embodiments. Since the clothing processing device according to this utility model is equipped with the heat exchanger in the above embodiments, the heat exchanger can improve the efficiency of the clothing processing device in processing clothing (such as drying clothing) through its own high-efficiency heat exchange performance, thereby improving the performance of the clothing processing device and the user experience.

[0020] In summary, the heat exchanger comprises a main body with multiple flow-dispersing components. These components include stacked baffles, each with multiple through-grooves spaced apart in the height direction and multiple protrusions spaced apart. The through-grooves extend in the width direction of the baffle and open to one side. During assembly, the baffle is inserted into the main body, and the through-grooves engage with the flat tubes on the main body, improving the efficiency of assembly and disassembly and the stability of the baffle assembly. The protrusions enhance the structural strength of the baffle, allowing it to withstand airflow impact. Through-grooves are positioned between adjacent protrusions. After the baffle is assembled into the heat exchanger, the protrusions can shield the flat tubes on both sides in the height direction, preventing lint from adhering to the tubes and causing airflow to accumulate on the side of the protrusions away from the flat tubes. This avoids the influence of lint on the flat tubes, improves the heat exchange efficiency of the heat exchanger, and also collects and accumulates lint for easy cleaning. Each protrusion has multiple protrusions spaced apart from each other in the width direction. The shape and number of protrusions can be set according to actual heat exchange requirements and the need to block lint, improving the flexibility of the baffle. The interference fit between two adjacent baffles improves the baffle's ability to block lint, thereby improving the heat exchanger's heat exchange efficiency.

[0034] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0035] The heat transfer capacity between the heat exchange tubes and fins in the existing heat exchanger structure is poor, resulting in low heat exchange efficiency. In addition, fine lint is usually blown to the surface of the heat exchanger by the airflow in the air duct. The lint entering the heat exchanger will affect the heat exchange effect.

[0036] The following is for reference. Figures 1-4 Describes a baffle element according to an embodiment of the present invention.

[0037] The heat exchanger according to this utility model includes a heat exchanger body, on which fins are formed. The fins are configured as flow-turbing elements, and the surface of the flow-turbing elements has protrusions.

[0038] The heat exchanger 2 according to this utility model is provided with a heat exchanger body 23 and a baffle 1. The baffle 1 is designed with a protrusion 12, which can effectively block the lint entering the heat exchanger. Specifically, during the operation of the heat exchanger 2, lint may enter the heat exchanger 2 with the airflow. When the baffle 1 is inserted into the heat exchanger body 23, the protrusion 12 can prevent the lint from contacting the heat exchange structure inside the heat exchanger body 23. The airflow exchanges heat with the heat exchange mechanism inside the heat exchanger body 23 to achieve the heat exchange effect of the heat exchanger, while the lint accumulates on the protrusion 12. That is, the protrusion 12 can act as a barrier to prevent the lint from penetrating further into the heat exchanger 2, thus preventing the lint from accumulating inside the heat exchanger 2, thereby protecting the operation of the heat exchanger 2 from the influence of lint and improving the heat exchange effect of the heat exchanger 2.

[0039] The protrusion 12 can also increase the turbulence effect of the turbulence component 1. When the airflow enters the heat exchanger 2, the protrusion 12 can break the laminar boundary layer of the airflow, promote turbulence, improve the heat transfer coefficient, and increase the heat exchange area of ​​the heat exchanger 2, thereby further improving the heat exchange efficiency of the heat exchanger 2.

[0040] Furthermore, the protrusion 12 facilitates the removal of lint. When lint accumulates on the protrusion 12, users or maintenance personnel can easily remove it by brushing or rinsing with water, without requiring complex disassembly or professional cleaning of the heat exchanger, thus reducing maintenance costs and time. Moreover, the protrusion 12 has a turbulence-reducing effect; the airflow on its surface generates periodic disturbances, further reducing lint deposition and lowering maintenance frequency.

[0041] According to one embodiment of the present invention, the baffle 1 is constructed as a plurality of baffles spaced apart in the thickness direction, and each baffle 1 has a protrusion 12 formed on at least one surface in the thickness direction. The arrangement of multiple baffles 1 can improve the baffle effect. The baffles 1 disturb the airflow in the heat exchanger 2, which can intensify the heat exchange between the airflow and the heat exchange mechanism in the heat exchanger 2, thereby improving the heat exchange efficiency of the heat exchanger 2. Each baffle 1 can be provided with a protrusion 12. In actual manufacturing, the protrusion 12 can be located on any one surface of the baffle 1 in the thickness direction, or the baffle 1 can be provided on both surfaces in the thickness direction. The protrusion 12 can improve the structural strength of the baffle 1 itself, so that the baffle 1 can better resist the impact of the airflow, and can also change the flow path of the airflow, increase the disturbance of the airflow by the baffle 1, and thus improve the heat exchange efficiency of the heat exchanger 2. In addition, the design of the protrusion 12 can improve the ability of the turbulence member 1 to block lint. When lint enters the heat exchanger body 23 with the airflow, the protrusion 12 can block the lint, preventing the lint from adhering to the heat exchange structure inside the heat exchanger 2 and affecting heat exchange, thereby improving the heat exchange efficiency of the heat exchanger 2.

[0042] According to one embodiment of the present invention, a through groove 11 is formed on the turbulence member 1. The end of the through groove 11 is open and adapted to cooperate with the heat exchanger body 23. The protruding direction of the protrusion 12 intersects with the extending direction of the through groove 11 to block the lint entering the heat exchanger 2.

[0043] The baffle 1 is provided with a through groove 11, which is open to one side. During assembly, the baffle 1 is inserted into the heat exchanger 2. At this time, the through groove 11 can engage with the structure on the heat exchanger body 23, improving the stability of the assembly of the baffle 1. The protrusion direction of the protrusion 12 intersects with the extension direction of the through groove 11. This intersection can be simply understood as follows: the through groove 11 extends in the width direction of the baffle 1, while the protrusion 12 is provided on at least one side of the baffle 1 in the thickness direction and protrudes in the thickness direction, so that the protrusion 12 can effectively block the lint entering the heat exchanger. Specifically, during the operation of the heat exchanger, lint may enter the heat exchanger with the airflow. When the baffle 1 is inserted into the heat exchanger body 23, the through groove 11 and the through groove 12 intersect. The structural snap-fit ​​mechanism within the heat exchanger body 23 secures the flow-turbing component 1. At this time, the protrusion 12 can prevent lint from contacting the heat exchange structure within the heat exchanger body 23, thus avoiding any impact on the heat exchange process between the airflow and the heat exchanger 2. The lint accumulates on the protrusion 12, which acts as a barrier to prevent lint from penetrating further into the heat exchanger 2, thus protecting the operation of the heat exchanger 2 from the influence of lint and improving the heat exchange efficiency of the heat exchanger 2.

[0044] According to one embodiment of the present invention, the spoiler 1 includes: a spoiler 10, wherein a plurality of spoilers 10 are stacked in the thickness direction, each spoiler 10 having a through groove 11 formed thereon, and each spoiler 10 having a protrusion 12 protruding from at least one side in the thickness direction of the spoiler 10.

[0045] The turbulence-disrupting component 1 is composed of multiple turbulence-disrupting plates 10 stacked in the thickness direction. The multi-layer structure design enhances the turbulence-disrupting effect of the turbulence-disrupting component 1. Each turbulence-disrupting plate 10 can disturb the flow of air. The stacking of multiple turbulence-disrupting plates 10 can further improve the disturbance of the circulating airflow of the heat exchanger after the turbulence-disrupting component 1 is assembled into the heat exchanger, thereby improving the heat exchange efficiency of the heat exchanger.

[0046] During the operation of the heat exchanger, the baffle 1 needs to withstand the impact of the airflow. The multi-layer structure design enhances the overall structural strength and stability of the baffle 1, enabling it to better disperse and withstand the impact of the airflow, thus ensuring the long-term reliable operation of the baffle 1.

[0047] Each baffle 10 has a protrusion 12 formed on it. The protrusion 12 protrudes on at least one side in the thickness direction of the baffle 10. Multiple baffles 10 stacked with multiple protrusions 12 form a multi-layer barrier to block lint, which increases the chance of lint being blocked and accumulating on the surface of the baffle 1, further reducing the possibility of lint entering the heat exchanger and thus protecting the core components of the heat exchanger.

[0048] According to one embodiment of the present invention, each spoiler 10 has a plurality of through slots 11 spaced apart in the height direction, and the protrusions 12 are configured to be a plurality of spaced apart in the height direction of the spoiler 10, with a through slot 11 provided between two adjacent protrusions 12.

[0049] Each baffle 10 has multiple through slots 11 spaced apart in the height direction. When the baffle 1 is assembled with the heat exchanger, the multiple through slots 11 can be engaged with the corresponding flat tubes 21, further improving the assembly stability of the baffle 1. Similarly, the protrusions 12 are also constructed as multiple protrusions spaced apart in the height direction. The arrangement of multiple protrusions 12 improves the efficiency of blocking lint. A through slot 11 is formed between two adjacent protrusions 12. When the baffle 10 is assembled to the heat exchanger, each through slot 11 corresponds to a flat tube 21. At this time, each flat tube 21 is shielded by protrusions 12 on both sides in the height direction, preventing lint from adhering to the flat tube 21 with the airflow during heat exchanger operation, thus improving the heat exchange effect of the heat exchanger.

[0050] Furthermore, the spaced arrangement of multiple protrusions 12 along the height of the baffle 10 enhances the structural rigidity of the baffle 10. As a supporting structure for the baffle 10, the protrusions 12 resist the pressure from airflow impact and lint accumulation, maintaining the shape and positional stability of the baffle 10 and ensuring the long-term reliable operation of the heat exchanger.

[0051] According to one embodiment of the present invention, each of the protrusions 12 is provided with a non-uniform thickness in the width direction of the baffle 10. The non-uniform thickness design of the protrusions 12 can generate more complex and intense turbulence when the airflow passes through the baffle 1, which helps to enhance the heat exchange between the airflow and the heat exchanger wall, thereby improving the heat exchange efficiency of the heat exchanger.

[0052] According to one embodiment of the present invention, the protrusion 12 includes a protrusion 121, wherein a plurality of protrusions 121 are configured to be spaced apart in the width direction of the spoiler 10, and the thickness of two adjacent protrusions 121 gradually decreases in the direction approaching each other. Figure 1 As shown, each protrusion 12 is provided with multiple protrusions 121 spaced apart from each other in the width direction of the baffle 1. The arrangement of multiple protrusions 121 strengthens the structural strength of the baffle 10, thereby increasing the service life of the baffle 1. The thickness of two adjacent protrusions 121 gradually decreases in the direction close to each other, making the protrusion 12 as a whole form a more complex shape. When the airflow passes through the baffle 1, more complex and variable turbulence is generated, which can enhance the heat exchange between the airflow and the heat exchanger wall and improve the heat exchange efficiency. Especially in the case of high-efficiency heat exchange, it can significantly improve the performance of the heat exchanger.

[0053] Furthermore, the number of protrusions 121 can be adjusted adaptively according to parameters such as the actual heat exchanger efficiency or the size and model of the baffles 10, offering high flexibility.

[0054] According to one embodiment of the present invention, the outer surface of each protrusion 121 in the thickness direction is constructed as an arcuate surface or a polygonal surface connected by multiple planes. The shape design of the protrusion 12 affects the effect of the airflow deflector 1 in blocking lint and disturbing the airflow. Specifically, the outer surface of each protrusion 121 in the thickness direction can be constructed as an arcuate surface or a polygonal surface connected by multiple planes. The arcuate surface can be understood as the overall shape of the protrusion 12 resembling a part of a sphere; while the polygonal surface can be understood as the protrusion 12 resembling a boss with multiple surfaces, such as a trapezoidal boss. The design of the arcuate or polygonal surface makes it easier for lint to be captured by the protrusion 121 and accumulate on its surface when it passes with the airflow. For example, the zigzag surface design creates multiple planar connections for the protrusion 12, which can form more positions to block lint and increase the chances of lint being blocked and accumulating by the protrusion 12. This further improves the ability of the turbulence-disrupting element 1 to block lint and prevents lint from entering the heat exchanger and affecting its operation. At the same time, the shape design of the protrusion 121 can also improve the ability of the turbulence-disrupting element 1 to disturb the airflow, increase the turbulence of the airflow, and thus improve the heat exchange efficiency of the heat exchanger.

[0055] According to one embodiment of the present invention, the distance between two adjacent spoilers 10 is not greater than the thickness of the protrusion 12. For example... Figure 4 As shown, the spoiler 1 is composed of multiple spoiler plates 10 stacked together. The distance between two adjacent spoiler plates 10 is no greater than the thickness of the protrusion 12. It can also be simply understood that the two adjacent spoiler plates 10 are interference fit, which means that the protrusion 12 can form a continuous blocking layer in the height direction of the spoiler 1. This ensures that when the lint passes through with the airflow, no matter which spoiler plate 10 it is between, it will be effectively blocked by the protrusion 12, thereby improving the continuity and reliability of the spoiler 1 in blocking lint.

[0056] According to one embodiment of the present invention, the heat exchanger body 23 includes a flat tube 21, which is constructed as a plurality of stacked tubes in the height direction, and each flat tube 23 is respectively housed in a corresponding through groove 11.

[0057] The heat exchange medium can flow inside the flat tube 21, and multiple flat tubes 21 can improve the heat exchange efficiency of the heat exchanger 2. When the turbulence-disrupting element 1 is inserted into the heat exchanger 2, the through groove 11 is respectively engaged with the corresponding flat tube 21. At this time, the turbulence-disrupting element 1 can disturb the airflow and increase the turbulence of the airflow, thereby improving the heat exchange efficiency of the heat exchanger 2. The protrusion 12 on the turbulence-disrupting element 1 can block the lint and prevent the lint from entering the interior of the heat exchanger 2, ensuring that the heat exchanger 2 can work normally and improving the heat exchange efficiency of the heat exchanger 2.

[0058] According to one embodiment of the present invention, one end of the flat tube 21 is connected to the same-side end of the adjacent flat tube 21, and the other end of the flat tube 21 is connected to the other end of the same-side flat tube 21 on the other adjacent side. For example... Figure 2 As shown, one end of the flat tube 21 is connected to the same end of the adjacent flat tube 21 on the same side, and the other end is connected to the other end of the same side of the adjacent flat tube 21 on the other side. This connection design allows the heat exchange medium (such as coolant) to form a continuous flow path between multiple flat tubes 21, enhancing the fluid flow and ensuring smooth flow of the fluid in the heat exchanger 2. The heat exchange medium can transfer heat to any position of the flat tube 21, increasing the area of ​​heat exchange between the flat tube 21 and the airflow, and improving the heat exchange efficiency of the heat exchanger 2.

[0059] In some embodiments, each heat exchanger includes a main body portion 131 and a comb portion 132. The comb portion 132 is disposed on the main body portion 131 in the width direction and extends in a direction away from the main body portion 131. The comb portion 132 is configured to be a plurality of comb portions spaced apart in the height direction. A through groove 11 is formed between two adjacent comb portions 132. Each comb portion 132 has a protrusion 12 on at least one side in the thickness direction.

[0060] In some embodiments, the heat exchanger 2 is provided with a plurality of heat exchanger bodies 23 spaced apart from each other in the width direction. Each heat exchanger body 23 can be connected to a plurality of baffles 1. It should be noted that when connecting, the baffles 1 need to be inserted in the forward direction on the side closer to the airflow, that is, the side first impacted by the airflow. The forward insertion here can be simply understood as the baffles 1 being inserted into the heat exchanger along the extension direction of the comb teeth 132, so as to ensure that the lint can be blocked on the body part 131 of the baffles 1 by the protrusions 12, ensuring that the lint will not enter the heat exchanger, and also facilitating the handling of the lint.

[0061] In some embodiments, the heat exchanger may be an evaporator.

[0062] The following is a brief description of the garment processing equipment according to this utility model.

[0063] The clothing processing device according to the present invention includes the heat exchanger 2 in the above embodiments. Since the clothing processing device according to the present invention is equipped with the heat exchanger 2 in the above embodiments, the heat exchanger 2 can improve the efficiency of the clothing processing device in processing clothing (such as drying clothing) through its own high-efficiency heat exchange performance, thereby improving the performance of the clothing processing device and the user experience.

[0064] In summary, the heat exchanger 2 is provided with a heat exchanger body 23, on which multiple flow-dispersing elements 1 are provided. Each flow-dispersing element 1 includes multiple stacked flow-dispersing plates 10. Each flow-dispersing plate 10 has multiple through slots 11 spaced apart in the height direction and multiple protrusions 12 spaced apart. The through slots 11 extend in the width direction of the flow-dispersing element 1 and open to one side. During assembly, the flow-dispersing element 1 is inserted into the heat exchanger, and the through slots 11 engage with the flat tubes 21 on the heat exchanger, improving the efficiency of disassembly and assembly of the flow-dispersing element 1. Stability; the protrusions 12 improve the structural strength of the baffle 1, enabling it to withstand airflow impact. A through groove 11 is provided between adjacent protrusions 12. When the baffle 1 is assembled into the heat exchanger, the protrusions 12 can shield the flat tube 21 on both sides of its height direction, preventing lint from adhering to the tube 21 and causing airflow to accumulate on the side of the protrusion 12 away from the flat tube 21. This avoids the influence of lint on the flat tube 21, improves the heat exchanger's efficiency, and also collects and removes lint. Each protrusion 12 has multiple protrusions 121 spaced apart in the width direction. The shape and number of protrusions 121 can be set according to actual heat exchange requirements and lint blocking needs, improving the flexibility of the baffle 1. The interference fit between adjacent baffles 10 enhances the baffle 1's ability to block lint, thereby improving the heat exchanger's efficiency.
