Abstract
Description
Technical Field
[0001] This utility model relates to the field of air conditioning device technology, and more specifically, to a radiator and an air conditioning device having the same. Background Technology
[0002] Currently, existing radiators include heat sinks with internal circulation channels. The heat source of the frequency converter module is attached to the heat sink to exchange heat with it.
[0003] In existing technologies, the flow channels within a heat sink are typically multiple straight channels connected in series or parallel along its length. However, the straight channels restrict the heat exchange process, affecting heat exchange efficiency and consequently resulting in poor heat dissipation performance of the radiator. Utility Model Content
[0004] The main objective of this invention is to provide a radiator and an air conditioning device having the same, in order to solve the problem of poor heat dissipation effect of radiators in the prior art.
[0005] To achieve the above objectives, according to one aspect of the present invention, a radiator is provided, comprising: a heat dissipation plate; the heat dissipation plate has a first refrigerant channel inside, the first refrigerant channel including at least one bent channel and at least two straight channels arranged along the length direction of the heat dissipation plate, the two ends of the bent channel being connected through the straight channels.
[0006] By applying the technical solution of this utility model, without changing the size of the heat sink, the above-mentioned setting of the bending channel can not only increase the length of the refrigerant flow in the first refrigerant channel and increase the heat dissipation area of the first refrigerant channel, thereby enhancing the heat exchange effect between the radiator and the heat source, but also prolong the passage time of the refrigerant through the heat source of the frequency converter module, so as to fully cool the heat source of the frequency converter module, thereby improving the overall heat exchange efficiency of the radiator and solving the problem of poor heat dissipation effect of the radiator in the prior art.
[0007] Furthermore, the bending channel includes: two first channel segments arranged opposite each other along the length of the heat sink, the first channel segments extending along the width of the heat sink; and a second channel segment, the two first channel segments being connected by the second channel segment to form a U-shaped structure. The U-shaped bending channel can further extend the path of the refrigerant within the heat sink, enhancing the heat exchange effect.
[0008] Furthermore, the bent channel also includes a first curved channel, through which the straight channel connects to the first channel segment, with the center of the first curved channel located outside the opening of the U-shaped structure; and / or, the bent channel also includes a second curved channel, through which the first channel segment connects to the second channel segment, with the center of the second curved channel located inside the opening of the U-shaped structure. This configuration not only increases the flexibility of refrigerant flow, better adapting to the shape of the heat sink and improving the heat exchange performance of the radiator, but also makes the refrigerant flow within the first refrigerant channel smoother. Simultaneously, by adjusting the radius of curvature of the first curved channel and / or the second curved channel, the cross-sectional area of the first curved channel differs from that of the straight channel and the first channel segment, creating turbulence and improving heat dissipation uniformity.
[0009] Furthermore, there may be one first refrigerant channel; or, there may be multiple first refrigerant channels, spaced apart along the width of the heat sink, with the bends on adjacent channels arranged opposite or staggered. The arrangement of one or more first refrigerant channels can be selected based on actual heat dissipation requirements, with multiple channels providing stronger heat dissipation capabilities. Simultaneously, this arrangement allows for greater flexibility in selecting the number of first refrigerant channels to meet different usage needs and operating conditions, and also improves the processing flexibility for operators.
[0010] Furthermore, on any given first refrigerant channel, there are multiple bent channels, spaced apart along the length of the heat sink. This arrangement of multiple bent channels further increases the flow path of the refrigerant, improving heat dissipation efficiency. Simultaneously, this arrangement allows for greater flexibility in selecting the number of bent channels on any given first refrigerant channel to meet different usage requirements and operating conditions, and also enhances the processing flexibility for operators.
[0011] Furthermore, when there are multiple first refrigerant channels, the bends on two adjacent first refrigerant channels are arranged opposite each other with their openings facing each other. This arrangement of the openings of the two bends promotes the uniform distribution of refrigerant on the heat sink, avoids localized overheating, and improves the overall heat dissipation effect.
[0012] Furthermore, the openings of multiple bends on any one of the first refrigerant channels face the same or opposite directions. The increase in bends means a longer flow path for the refrigerant within the radiator, increasing the contact area with the heat sink and thus improving heat exchange efficiency. Simultaneously, by setting bends at multiple locations, it ensures that the refrigerant is evenly distributed throughout the heat source area of the inverter module, avoiding localized overheating and resulting in a more uniform overall temperature distribution, thus improving system reliability and efficiency.
[0013] Furthermore, the radiator includes multiple first refrigerant channels spaced apart along the width of the heat sink. The radiator also includes a second refrigerant channel, also along the width of the heat sink, located between adjacent first refrigerant channels, which are connected to each other. This arrangement of the second refrigerant channel further optimizes refrigerant distribution and improves heat dissipation uniformity. Simultaneously, this arrangement ensures smooth refrigerant flow within the radiator, thereby enhancing its heat dissipation reliability.
[0014] Furthermore, the radiator also includes a third refrigerant channel, located along the width of the heat sink plate between two adjacent first refrigerant channels. The third refrigerant channel is situated within the heat sink plate, and the first refrigerant channels are connected to the third refrigerant channel via second refrigerant channels. This arrangement of the third refrigerant channel enhances refrigerant circulation and improves heat dissipation efficiency. Simultaneously, this arrangement also improves the cooling system's response speed, adapts to rapidly changing operating conditions of the equipment, and enhances the stability and lifespan of the radiator.
[0015] According to another aspect of the present invention, an air conditioning device is provided, including the radiator described above. Attached Figure Description

[0031] To address the problem of poor heat dissipation performance of radiators in the prior art, this application provides a radiator and an air conditioning device having the same.
[0032] Example 1
[0033] like Figure 1 As shown, the radiator includes a heat sink 10 and a first refrigerant channel 20. The heat sink 10 has a first refrigerant channel 20 inside, which includes at least one bent channel 21 and at least two straight channels 22 arranged along the length of the heat sink 10. The two ends of the bent channel 21 are connected by the straight channels 22.
[0034] By applying the technical solution of this embodiment, without changing the size of the heat sink 10, the above-mentioned arrangement of the bending channel 21 can not only increase the length of the refrigerant flow in the first refrigerant channel 20 and increase the heat dissipation area of the first refrigerant channel 20, thereby enhancing the heat exchange effect between the radiator and the heat source, but also prolong the passage time of the refrigerant through the heat source of the frequency converter module, so as to fully cool the heat source of the frequency converter module, thereby improving the overall heat exchange efficiency of the radiator and solving the problem of poor heat dissipation effect of the radiator in the prior art.
[0035] like Figure 1 As shown, the bent channel 21 includes two first channel segments 211 and a second channel segment 212 arranged opposite to each other along the length of the heat sink 10. The first channel segments 211 extend along the width of the heat sink 10. The two first channel segments 211 are connected by the second channel segment 212 to form a U-shaped structure. This U-shaped bent channel 21 further extends the path of the refrigerant within the heat sink 10, enhancing the heat exchange effect.
[0036] In this embodiment, the first channel segment 211 and the second channel segment 212 are arranged perpendicularly to each other. The U-shaped bend channel 21 not only increases the flow path of the refrigerant, but also optimizes the distribution of the refrigerant, making the heat dissipation effect more uniform and avoiding the problem of local overheating.
[0037] Optionally, the bent channel 21 further includes a first curved channel 23, through which the straight channel 22 connects to the first channel segment 211, with the center of the first curved channel 23 located outside the opening 213 of the U-shaped structure; and / or, the bent channel 21 further includes a second curved channel 24, through which the first channel segment 211 connects to the second channel segment 212, with the center of the second curved channel 24 located inside the opening 213 of the U-shaped structure. This arrangement not only increases the flexibility of refrigerant flow, better adapting to the shape of the heat sink 10 and improving the heat exchange performance of the radiator, but also makes the refrigerant flow within the first refrigerant channel 20 smoother, avoiding turbulence or flow that could affect the normal flow of the refrigerant. Simultaneously, by adjusting the radius of curvature of the first curved channel 23 and / or the second curved channel 24, the cross-sectional areas of the first curved channel 23, the straight channel 22, and the first channel segment 211 are different, creating turbulence and improving heat dissipation uniformity.
[0038] In this embodiment, the bending channel 21 further includes a first curved channel 23 and a second curved channel 24. The straight channel 22 is connected to the first channel segment 211 through the first curved channel 23, and the center of the first curved channel 23 is located outside the opening 213 of the U-shaped structure. The first channel segment 211 is connected to the second channel segment 212 through the second curved channel 24, and the center of the second curved channel 24 is located inside the opening 213 of the U-shaped structure.
[0039] Specifically, there are two first curved channels 23 and two straight channels 22, each straight channel 22 being connected to the first channel segment 211 through one first curved channel 23. There are two second curved channels 24, each first channel segment 211 being connected to the second channel segment 212 through one second curved channel 24.
[0040] Optionally, there may be one first refrigerant channel 20; or, there may be multiple first refrigerant channels 20, spaced apart along the width of the heat sink 10, with the bent channels 21 on adjacent first refrigerant channels 20 arranged opposite to or staggered. This allows for selection of one or more first refrigerant channels 20 based on actual heat dissipation requirements, and the design of multiple first refrigerant channels 20 provides stronger heat dissipation capacity. Furthermore, this configuration makes the selection of the number of first refrigerant channels 20 more flexible, meeting different usage needs and operating conditions, and also improving the processing flexibility of operators.
[0041] In this embodiment, there are multiple first refrigerant channels 20. The above-mentioned arrangement of multiple first refrigerant channels 20 can effectively cope with the heat dissipation requirements of high heat density, improve the heat dissipation capacity of the radiator, and also ensure that the equipment operates stably under high load, avoiding performance degradation and hardware damage caused by overheating.
[0042] Optionally, multiple bends 21 can be provided on any one of the first refrigerant channels 20, with these multiple bends 21 spaced apart along the length of the heat sink 10. This arrangement of multiple bends 21 further increases the flow path of the refrigerant and improves heat dissipation efficiency. Simultaneously, this arrangement allows for greater flexibility in selecting the number of bends 21 on any one of the first refrigerant channels 20 to meet different usage requirements and operating conditions, and also enhances the processing flexibility for operators.
[0043] In this embodiment, a single bend channel 21 is formed on any one of the first refrigerant channels 20, making the structure of the first refrigerant channel 20 simpler, easier to process and implement, and reducing the processing cost and difficulty of the first refrigerant channel 20.
[0044] Optionally, the openings of the multiple bends 21 on any one of the first refrigerant channels 20 may face the same or opposite directions. In this way, the above-mentioned arrangement of the openings 213 of the two bends 21 can promote the uniform distribution of refrigerant on the heat sink 10, avoid local overheating, and improve the overall heat dissipation effect.
[0045] In this embodiment, the two opposing bends 21 on the two adjacent first refrigerant channels 20 can promote the uniform distribution of refrigerant on the heat sink, thereby effectively avoiding local overheating and improving the overall thermal stability of the equipment. Simultaneously, the above arrangement can also reduce the flow resistance of the refrigerant and improve the circulation efficiency of the air conditioning unit.
[0046] like Figure 1As shown, there are multiple first refrigerant channels 20, which are spaced apart along the width of the heat sink 10. The radiator also includes second refrigerant channels 30. Along the width of the heat sink 10, the second refrigerant channels 30 are located between two adjacent first refrigerant channels 20, and the two adjacent first refrigerant channels 20 are connected through the second refrigerant channels 30. The openings of the bends 21 on each first refrigerant channel 20 face the second refrigerant channel 30. This arrangement of the second refrigerant channels 30 further optimizes the distribution of refrigerant and improves the uniformity of heat dissipation. Simultaneously, this arrangement ensures that the refrigerant can flow smoothly within the radiator, thereby improving the heat dissipation reliability of the radiator.
[0047] Specifically, the design of the second refrigerant channel 30 not only improves heat dissipation uniformity and enhances refrigerant circulation, but also helps reduce refrigerant consumption and lower operating costs.
[0048] This application also provides an air conditioning device (not shown) including the radiator described above.
[0049] Example 2
[0050] The difference between the radiator in Embodiment 2 and Embodiment 1 is that the number of bends 21 on any one of the first refrigerant channels 20 is different.
[0051] Optionally, the first refrigerant channel 20 may have multiple bent channels 21, with the openings of the multiple bent channels 21 facing the same or opposite directions. This increase in the number of bent channels 21 means a longer flow path for the refrigerant within the radiator, increasing the contact area with the heat sink and thus improving heat exchange efficiency. Simultaneously, by setting bent channels 21 at multiple locations, it can be ensured that the refrigerant is evenly distributed throughout the heat source area of the inverter module, avoiding localized overheating and resulting in a more uniform overall temperature distribution, thereby improving the reliability and efficiency of the system.
[0052] like Figure 2 As shown, on any one of the first refrigerant channels 20, there are two bent channels 21. The two bent channels 21 are arranged at intervals along the length direction of the first refrigerant channel 20 (the length direction of the heat sink 10), which can significantly improve the heat dissipation efficiency of the heat sink.
[0053] In this embodiment, on any one of the first refrigerant channels 20, the openings of the multiple bend channels 21 face the same direction so that the refrigerant flow direction is consistent. This helps to improve the continuity and stability of the fluid, reduce resistance and eddies during the flow process, and allow the refrigerant to flow more smoothly, thereby improving heat dissipation efficiency.
[0054] In this embodiment, the openings of the bends 21 on the two adjacent first refrigerant channels 20 are arranged in opposite directions.
[0055] In other embodiments not shown in the accompanying drawings, the openings of multiple bends in any one of the first refrigerant channels face opposite directions, thereby forming an interleaved flow pattern, increasing the turbulence of the fluid, and further promoting heat exchange.
[0056] It should be noted that the number of bends 21 on any one of the first refrigerant channels 20 is not limited to this and can be adjusted according to the working conditions and usage requirements.
[0057] Optionally, on any one of the first refrigerant channels 20, there may be three, four, five, six, or more bend channels 21.
[0058] Example 3
[0059] The difference between the radiator in Embodiment 3 and Embodiment 1 is that the bent channels 21 on the two adjacent first refrigerant channels 20 are positioned differently.
[0060] like Figure 3 As shown, when there are multiple first refrigerant channels 20, the bends 21 on adjacent first refrigerant channels 20 are staggered. The opening 213 of the bend 21 on the first first refrigerant channel 20 faces the second first refrigerant channel 20, and the opening 213 of the bend 21 on the second first refrigerant channel 20 faces the first first refrigerant channel 20. This staggered arrangement of the two bends 21 avoids direct interference with refrigerant flow, improves heat dissipation efficiency, optimizes heat dissipation effect, and effectively improves heat dissipation efficiency, thereby reducing the overall size of the radiator and increasing its integration.
[0061] Example 4
[0062] The difference between the radiator in Embodiment 4 and Embodiment 3 is that the opening orientation of the bent channel 21 on the two adjacent first refrigerant channels 20 is different.
[0063] like Figure 4 As shown, when there are multiple first refrigerant channels 20, the bends 21 on adjacent first refrigerant channels 20 are staggered. The opening 213 of the bend 21 on the first first refrigerant channel 20 faces away from the second first refrigerant channel 20, and vice versa. This staggered arrangement of the two bends 21 avoids direct interference with refrigerant flow, improves heat dissipation efficiency, optimizes heat dissipation, and effectively increases the overall size and integration of the radiator.
[0064] Example 5
[0065] The difference between the radiator in Embodiment 5 and Embodiment 3 is that the opening orientation of the bent channel 21 on the two adjacent first refrigerant channels 20 is different.
[0066] like Figure 5 As shown, when there are multiple first refrigerant channels 20, the bends 21 on adjacent first refrigerant channels 20 are staggered. The opening 213 of the bend 21 on the first first refrigerant channel 20 faces away from the second first refrigerant channel 20, while the opening 213 of the bend 21 on the second first refrigerant channel 20 faces the first first refrigerant channel 20. This staggered arrangement of the two bends 21 avoids direct interference with refrigerant flow, improves heat dissipation efficiency, optimizes heat dissipation effect, and effectively increases heat dissipation efficiency, thereby reducing the overall size of the radiator and improving its integration.
[0067] Example 6
[0068] The difference between the radiator in Example 6 and Example 1 is that the channels inside the radiator are different.
[0069] like Figure 6 As shown, the radiator also includes a third refrigerant channel 40. Along the width of the heat sink 10, the third refrigerant channel 40 is located between two adjacent first refrigerant channels 20, and the first refrigerant channels 20 are connected to the third refrigerant channel 40 via second refrigerant channels 30. This arrangement of the third refrigerant channel 40 enhances refrigerant circulation and improves heat dissipation efficiency. Simultaneously, this arrangement also improves the response speed of the cooling system, adapts to rapidly changing operating conditions of the equipment, and enhances the stability and service life of the radiator.
[0070] In this embodiment, there are two first refrigerant channels 20 and one third refrigerant channel 40. Each first refrigerant channel 20 is connected to the third refrigerant channel 40 via a second refrigerant channel 30. The third refrigerant channel 40 is a straight channel. Thus, the three refrigerant channels work together to cool the cooling module, increasing the cooling effect.
[0071] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:
[0072] Without changing the size of the heat sink, the above-mentioned setting of the bent channel can not only increase the length of the refrigerant flow in the first refrigerant channel and increase the heat dissipation area of the first refrigerant channel to enhance the heat exchange effect between the heat sink and the heat source, but also prolong the passage time of the refrigerant through the heat source of the frequency converter module to fully cool the heat source of the frequency converter module, thereby improving the overall heat exchange efficiency of the heat sink and solving the problem of poor heat dissipation effect of the heat sink in the prior art.
