Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, and in particular to a heat dissipation structure for a heat exchanger. Background Technology

[0002] In heat exchangers (such as condensers or evaporators used in air conditioning systems), the fluid inside the heat exchange tubes is at a higher temperature, while the cooling medium outside the tubes (such as air or water) is at a lower temperature. To ensure continuous heat transfer from the fluid inside the tubes to the medium outside, a temperature difference must be maintained. This requires timely heat dissipation from the heat exchange tubes. If heat is not dissipated, the temperature of the medium outside the tubes will rise rapidly as heat is absorbed, reducing the temperature difference between the inside and outside of the tubes. A reduced temperature difference slows down heat transfer and decreases heat exchange efficiency. Existing heat exchangers typically do not have dedicated heat dissipation structures for the heat exchange tubes or utilize fans or other structures to dissipate heat from the outside of the heat exchange tubes, resulting in poor heat dissipation and impacting heat exchange efficiency.

Detailed Implementation

[0026] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0027] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0029] See Figures 1 to 6 This utility model discloses a heat dissipation structure for a heat exchanger, including a heat exchange component 20 and a heat dissipation component 10. The heat dissipation component 10 includes a heat dissipation base 13, a first heat dissipation fin 11 and a second heat dissipation fin 12. The first heat dissipation fin 11 and the second heat dissipation fin 12 are spaced apart in the heat dissipation base 13. A second heat dissipation fin 12 is provided between two adjacent first heat dissipation fins 11. A heat exchange channel 121 is provided on the second heat dissipation fin 12. The heat exchange component 20 is installed in the heat exchange channel 121.

[0030] Based on the above structure, during assembly, multiple first heat sinks 11 can be arranged in the heat sink 13. Each pair of adjacent first heat sinks 11 can be arranged side by side and opposite each other, or arranged vertically opposite each other. A second heat sink 12 is arranged between each pair of adjacent first heat sinks 11. In this way, the outer periphery of the heat exchange channel 121 provided on the second heat sink 12 can be surrounded by the first heat sinks 11 and the second heat sink 12, so that the heat inside the heat exchange channel 121 can be discharged through the multiple first heat sinks 11 and the second heat sink 12.

[0031] In practical use, the heat exchanger 20 is installed inside the heat exchange channel 121. When the heat of the heat exchange medium inside the heat exchanger 20 is transferred to the shell of the heat exchanger 20, the shell of the heat exchanger 20 transfers the heat to the inner wall of the heat exchange channel 121. Since multiple first heat sinks 11 and second heat sinks 12 are provided on the outer periphery of the heat exchange channel 121, the heat on the inner wall of the heat exchange channel 121 can be carried away by the multiple first heat sinks 11 and second heat sinks 12 at the same time, so as to accelerate the heat dissipation of the heat exchanger 20 and improve the heat dissipation efficiency.

[0032] Specifically, when the heat exchanger heat dissipation structure of this embodiment is applied to an air conditioning system, during the heat exchange process of the air conditioner, there is a temperature difference between the refrigerant temperature inside the heat exchange component 20 (such as the heat exchange tube in the evaporator or condenser) and the surrounding environment (air or other cooling medium). After the heat exchange component 20 is installed in the heat exchange channel 121, the multiple first heat dissipation fins 11 and second heat dissipation fins 12 on the outer periphery of the heat exchange channel 121 can quickly dissipate heat to the outer periphery of the heat exchange channel 121, making the heat dissipation of the outer periphery of the heat exchange component 20 faster. When the outer periphery dissipates heat quickly, the temperature of the surrounding environment can be rapidly reduced and kept at a low level. For example, in the air conditioner condenser, the refrigerant is in a high-temperature gaseous state and needs to dissipate heat to the outside and liquefy. If the outer periphery dissipates heat quickly, a large temperature difference between the refrigerant inside the tube and the air outside the tube can be maintained. A large temperature difference can drive heat to be transferred from the inside of the heat exchange component 20 to the outer periphery more quickly, thereby improving the heat exchange efficiency.

[0033] More specifically, during the heat exchange process, there is a temperature difference between the inner and outer walls of the heat exchanger 20 (such as a shell-and-tube heat exchanger or a shell-and-tube heat exchanger). When heat dissipation cannot be achieved quickly, this temperature difference will further increase. Due to the principle of thermal expansion and contraction, different temperatures will cause different parts of the heat exchange tube to expand or contract to different degrees, which may cause the heat exchange tube to bulge or crack, affecting the use of the heat exchanger 20. Therefore, by using the heat dissipation structure of the heat exchanger in this embodiment, the heat exchanger 20 can be quickly cooled by multiple first heat dissipation fins 11 and second heat dissipation fins 12, which can also reduce the risk of bulging or cracking of the heat exchanger 20 during use and indirectly improve the service life of the heat exchanger 20.

[0034] It should be noted that the heat exchange channel 121 in this embodiment can be a pipe or cavity integrally formed on the second heat sink 12, or it can be a structure such as an installation pipe or shell connected to the second heat sink 12 by welding or gluing on the outer periphery of the second heat sink 12, so that the heat exchange channel 121 is formed on the second heat sink 12. Each pair of first heat sinks 11 can be arranged opposite each other at both ends of the second heat sink 12, or they can be arranged opposite each other at both ends of the second heat sink 12, and are respectively connected to the outer periphery of the heat exchange channel 121, so that the heat in the heat exchange channel 121 can be dissipated simultaneously through multiple first heat sinks 11 and second heat sinks 12, thereby improving the heat dissipation efficiency of the entire structure.

[0035] In addition, the number of the second heat sink 12 and the heat exchange channel 121 can be set to multiple according to the actual heat dissipation requirements. Specifically, the heat sink 13, the first heat sink 11 and the second heat sink 12 can all be made of materials with thermal conductivity such as aluminum or copper. The first heat sink 11 and the second heat sink 12 can be formed on the heat sink 13 by welding or integral molding.

[0036] Preferably, the second heat sink 12 in this embodiment includes a heat dissipation section 122 and an arc section 123. During assembly, the two ends of the arc section 123 are respectively connected to the two first heat sinks 11. The heat dissipation section 122 is located between the two first heat sinks 11 and is connected to the arc section 123. Since the inner wall of the arc section 123 is usually concave arc, the arc section 123 has an integrally formed heat exchange channel 121 for the installation of the heat exchange component 20. In this way, the heat exchange component 20 can be directly installed to the arc section 123 without the need to set up additional pipes or cavities to install the heat exchange component 20, and the structure is simpler.

[0037] Furthermore, since the arc segment 123 is connected to the heat dissipation segment 122 and the first heat sink 11 respectively, the heat released by the heat exchanger 20 can be more directly and quickly transferred to the heat dissipation segment 122 and the first heat sink 11 through the arc segment 123 itself after the heat exchanger 20 is installed on the arc segment 123, thereby indirectly improving the heat dissipation efficiency.

[0038] It should be noted that the heat dissipation section 122 and the first heat sink 11 can be vertical or horizontally connected to the outer periphery of the arc section 123. Specifically, they can be set on the outer periphery of the arc section 123 by welding or integral molding.

[0039] Furthermore, multiple heat sinks 13 are provided, and the multiple heat sinks 13 extend along the first direction. Each pair of adjacent heat sinks 13 can be detachably connected and form a heat sink 10. The arc segments 123 on each pair of adjacent second heat sinks 12 are arranged opposite each other and enclose each other after the adjacent two heat sinks 13 are connected to form a heat exchange channel 121, so as to form multiple heat exchange channels 121. Multiple heat exchange components 20 are provided, and the multiple heat exchange components 20 are respectively installed in the multiple heat exchange channels 121.

[0040] Specifically, the following explanation takes the horizontal direction of the heat sink 10 in the first direction as an example. By extending multiple heat sinks 13 along the first direction, the heat dissipation area of ​​the entire heat sink 10 is increased by multiple first heat sinks 11 and second heat sinks 12 inside the multiple heat sinks 13. This allows the heat sink 10 to dissipate heat simultaneously through multiple first heat sinks 11 and second heat sinks 12, resulting in higher heat dissipation efficiency.

[0041] In addition, since the multiple heat sinks 13 are detachably connected, the entire heat sink 10 is easy to disassemble and assemble. During assembly, two adjacent heat sinks 13 are first separated, so that the two adjacent arc segments 123 are separated. At this time, the heat exchanger 20 is installed onto one of the arc segments 123. After the heat exchanger 20 is installed, the heat sinks 13 are connected so that the two arc segments 123 surround it for the heat exchanger 20 to be installed. In this way, the heat exchanger 20 is more stable after installation because the two arc segments 123 surround it. When the heat exchanger 20 needs to be replaced or maintained in the future, only the two adjacent heat sinks 13 need to be separated, which is convenient for later maintenance.

[0042] More specifically, with multiple heat exchangers on the heat sink 13, multiple heat exchange channels 121 are also provided. Therefore, in this embodiment, multiple heat exchangers 20 are provided, and the multiple heat exchangers 20 are respectively installed inside the multiple heat exchange channels 121 so as to introduce more heat exchange medium through the multiple heat exchangers 20 and improve the heat exchange efficiency of the entire structure.

[0043] It should be noted that in this embodiment, each pair of adjacent heat sinks 13 can be connected by a detachable connection such as snap-fit ​​or plug-in. For example, a matching hook and slot can be designed at the connection part of the heat sink 13. By inserting the hook into the slot and locking it, the two can be snap-fit ​​connected. Alternatively, a plug-in connection can be used, such as setting a connector or pin on one of the heat sinks 13, and then inserting the connector or pin into the corresponding hole on the other heat sink 13 to form a tight fit connection.

[0044] Furthermore, the heat exchanger 20 includes a heat exchange tube, which includes multiple vertical sections 21 and multiple curved sections. The multiple vertical sections 21 are arranged at intervals along the first direction and are respectively installed in multiple heat exchange channels 121. Each pair of adjacent vertical sections 21 are connected and interconnected by the curved sections.

[0045] Based on the above structure, the heat exchange tube includes multiple vertical sections 21 and multiple curved sections. The multiple vertical sections 21 are arranged at intervals along the first direction (that is, the transverse direction of the heat sink 10). Each pair of adjacent vertical sections 21 are connected by a curved end and are interconnected with each other. The connection between the multiple vertical sections 21 and the multiple curved sections extends the length of the heat exchange tube, thereby increasing the contact area between the heat exchange medium and the heat exchange tube, making the heat transfer more complete and improving the heat exchange efficiency.

[0046] Preferably, the heat exchange tube can be made of existing high thermal conductivity and corrosion resistant materials such as aluminum alloy, copper alloy or titanium alloy to prevent corrosion by the heat exchange medium during long-term use.

[0047] Furthermore, each pair of adjacent arc segments 123 is provided with a first snap-fit ​​part and a second snap-fit ​​part, and the first snap-fit ​​part and the second snap-fit ​​part are engaged and connected so that the two adjacent arc segments 123 can be detachably connected.

[0048] Based on this structure, during assembly, a snap-fit ​​hole, a slot, or a snap ring can be provided on one of the arc segments 123, and a snap-fit ​​strip, a hook, or a block can be provided on the other arc segment 123, so that the two can be snapped together. This allows the two adjacent arc segments 123 to be disassembled and assembled without the need for additional tools, making the operation convenient and quick, and enabling rapid disassembly and assembly.

[0049] Preferably, in this embodiment, the first snap-fit ​​part is a snap-fit ​​block 124 and the second snap-fit ​​part is a snap-fit ​​groove 125. The snap-fit ​​block 124 and the snap-fit ​​groove 125 are arranged correspondingly so that the snap-fit ​​block 124 can snap into the snap-fit ​​groove 125, so that the two are snapped together.

[0050] More specifically, in this embodiment, each pair of adjacent heat sinks 13 is provided with a third latching part 131 and a fourth latching part, which are latched together to make the two adjacent heat sinks 13 detachably connected. Specifically, the third latching part 131 can be a latching strip, a latching hook, or a buckle on one of the heat sinks 13, while the fourth latching part can be a slot, a latching hole, or a latching ring on the other heat sink 13, so that the two can be latched together and can be disassembled and assembled without the aid of tools, making the operation convenient.

[0051] Furthermore, heat dissipation patterns 14 are provided on the outer periphery of the heat sink 10. The heat dissipation patterns 14 extend along the circumference of the heat sink 10 so that a heat dissipation surface is formed on the outer periphery of the heat sink 10.

[0052] Based on this structure, by setting multiple heat dissipation patterns 14 on the outer periphery of the heat sink 10, the heat dissipation patterns 14 can be multiple raised stripes, wavy patterns or serrated patterns. In this way, both the raised and recessed parts of the heat dissipation patterns 14 can come into contact with the air. Compared with a smooth surface, the actual contact area between the surface of the heat sink 10 and the air is increased, making the heat dissipation surface on the outer periphery of the heat sink 10 larger. Thus, after the heat is transferred to the heat dissipation surface through multiple first heat sinks 11 and second heat sinks 12, the larger heat dissipation surface can be transferred to the air more quickly, improving the heat dissipation efficiency.

[0053] Furthermore, during assembly, two covers 30 are provided at both ends of the heat sink 10. The two covers 30 are arranged opposite each other in the second direction (that is, the width direction of the heat sink 10) so that the two covers 30 are respectively covered at both ends of the heat sink 10, preventing the ends of the heat sink 10 from being exposed to the outside and corroded by impurities in the external environment, thereby indirectly improving the service life of the entire structure.

[0054] Specifically, in order to avoid the cover 30 being completely sealed at both ends of the heat sink 10, resulting in poor internal heat dissipation, multiple heat dissipation holes 31 are provided on the cover 30. The multiple heat dissipation holes 31 are distributed at intervals on the cover 30, so that the heat at both ends of the heat sink 10 can be discharged through the heat dissipation holes 31, thereby further improving the heat dissipation efficiency of the heat sink 10.

[0055] More specifically, the heat dissipation holes 31 are strip-shaped holes, and multiple strip-shaped holes are arranged at an angle. Compared with vertical or horizontal heat dissipation holes 31, the angled holes can form a more complex airflow path between the inside and outside of the device, increasing the contact area between the air and the inside of the heat sink 10, thereby improving the convective heat transfer efficiency.

[0056] In addition, the inclined strip-shaped holes can block dust and foreign objects from entering the equipment to a certain extent. Since dust particles usually fall vertically under the action of gravity or drift horizontally with the wind, when dust particles float in the air and approach the heat dissipation hole 31, the inclined holes can block the vertically falling dust to a certain extent, thereby reducing the probability of dust entering the heat dissipation component 10.

[0057] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
