Description

Technical Field

[0001] The present application relates to the technical field of radiators, and in particular to a fin with a drainage function, an anti-frost radiator and a vehicle. Background Art

[0002] For new energy vehicles, a heat pump air conditioning system is usually equipped to improve the winter cruising range. For some heat pump air conditioning systems, a low-temperature radiator is required to also have the function of an outdoor heat exchanger, that is, when the outdoor environment is relatively low in winter, heat is absorbed from the ambient air by the coolant with a lower temperature in the radiator. This operating condition can be called the heat pump operating point. At this time, since the ambient air flows through the radiator with a lower temperature, the water vapor contained therein will condense into liquid water and stay on the surface of the radiator, and even further cool down and freeze to cover the surface of the radiator, that is, the frosting phenomenon. When the surface of the radiator is frosted, the comprehensive heat transfer efficiency between the outer surface of the radiator and the outdoor air will be greatly reduced, thereby reducing the heat transfer efficiency and significantly decreasing the heat transfer amount.

[0003] In order to solve the frosting problem, fins with a drainage structure are used. However, for the radiator of a new energy vehicle, in order to increase the space in the front trunk of the new energy vehicle, the radiator is usually arranged obliquely as a whole, while not reducing the core area and reducing the vertical height at the same time, which is convenient for the overall vehicle layout.

[0004] The inclined arrangement of the radiator will lead to a reduction in the utilization rate of the oncoming wind and a certain degree of reduction in the heat transfer performance. At the same time, the fins of the existing inclined radiator do not have an anti-frost function and are prone to frosting under the heat pump operating condition, and the performance will further decline at this time. In addition, the existing fins with a drainage structure on the market have a single function, and no targeted optimization design is carried out for the inclined radiator, the drainage effect is average, and there is no improvement in the heat dissipation performance.

[0005] Therefore, it is necessary to design a fin with a drainage function to solve the above problems. Utility Model Content

[0006] In view of this, in order to overcome the defects of the prior art, the present utility model provides a fin with a drainage function, an anti-frost radiator and a vehicle, effectively solving the problem that the radiator with an inclined arrangement of the existing new energy vehicle does not have an anti-frost function.

[0007] According to a first aspect of the present utility model, there is provided a fin with a drainage function for a radiator. When the radiator is installed on a vehicle, a first included angle is formed between the radiator and the horizontal plane. Among them, the fin with a drainage function includes a serpentine fin body, and the serpentine fin body includes a plurality of vertical plate members and a plurality of bending portions. Two adjacent vertical plate members are connected by one of the bending portions; a drainage opening is provided at an end of the vertical plate member, and a second included angle is formed between the drainage opening and a side of the vertical plate member, and the angle of the second included angle is equal to the angle of the first included angle.

[0008] Preferably, drainage openings are provided at both ends of the vertical plate member in a first direction and at both ends in a second direction; the vertical plate member includes a first end and a second end in the first direction, and the opening direction of the drainage opening at the first end is opposite to the opening direction of the drainage opening at the second end.

[0009] Preferably, the size of the drainage opening in the first direction is one-eighth to one-third of the size of the vertical plate member in the first direction.

[0010] Preferably, the second included angle is 10° - 60°, the size of the drainage opening in the second direction is 0.45 mm - 1.5 mm, and the size of the drainage opening in the third direction is 0.1 mm - 0.3 mm.

[0011] According to a second aspect of the present utility model, there is provided an anti-frosting radiator, wherein the anti-frosting radiator includes the fin with a drainage function as described above.

[0012] Preferably, the anti-frosting radiator further includes a plurality of spaced-apart heat dissipation tubes and an outer frame body. The plurality of heat dissipation tubes are arranged inside the outer frame body, and the fin with a drainage function is arranged between two adjacent heat dissipation tubes and between the heat dissipation tubes and the outer frame body.

[0013] Preferably, the bending portion abuts against the heat dissipation tube.

[0014] Preferably, the end of the heat dissipation tube is formed into an arc shape, and the top or bottom of the drainage opening is close to the end of the heat dissipation tube.

[0015] Preferably, the outer frame body includes side plates, water chambers, main plates, and mounting brackets. The water chambers are arranged on both sides of the heat dissipation tubes, the water chambers are communicated with the heat dissipation tubes through the main plates, the side plates are arranged between the two water chambers, and the mounting brackets are arranged on the water chambers.

[0016] According to a third aspect of the present utility model, there is provided a vehicle, wherein the vehicle includes the anti-frosting radiator as described above.

[0017] The fin with a drainage function according to the present utility model has a plurality of drainage openings formed in the serpentine fin body. By using these drainage openings, the surface tension of the liquid droplets can be broken, causing them to decompose into smaller-sized droplets, enabling the condensed water to be quickly discharged. At the same time, since the drainage openings are arranged at an angle with respect to the vertical plate member, after the serpentine fin body is installed, the position of the drainage openings is closer to the vertical direction, making full use of the gravity of the condensed water droplets and further facilitating the rapid flow of the condensed water. In addition, the drainage openings can cause the flowing air to generate turbulence, increasing the turbulence intensity on the air side and further increasing the convective heat transfer coefficient, thereby enhancing the heat exchange performance of the radiator.

Rather, the examples described herein are provided only to illustrate some of the many possible ways of implementing the methods, devices, and / or systems described herein that will be obvious after understanding the disclosure of the present application.

[0031] Throughout the specification, when an element (such as a layer, region, or substrate) is described as "on" another element, "connected to" another element, "bonded to" another element, "above" another element, or "covering" another element, it can be directly "on" another element, "connected to" another element, "bonded to" another element, "above" another element, or "covering" another element, or there can be one or more other elements between them.

[0038] According to a first aspect of the present utility model, there is provided a fin with a drainage function, as Figures 1 to 6 shown, the fin with a drainage function is for a radiator, and is particularly applicable to a radiator obliquely installed in a new energy vehicle. As Figure 7As shown, the angle between the inclined radiator and the following horizontal plane S4 is the first angle 2. Generally, for the convenience of installation and cooperation with the vehicle body, without reducing the heat dissipation area of the core and ensuring the heat dissipation performance, the first angle 2 is usually 10° - 60°. The fin with drainage function includes a fin body 1 formed in a serpentine shape.

[0039] In the following description, reference will be made to Figures 1 to 6 Specifically describe the detailed structure of the fin with drainage function. In addition, in the description of the embodiment, three directions and one plane are also involved, namely the first direction S1, the second direction S2, the third direction S3 and the horizontal plane S4, as Figure 1 and Figure 2 shown, the first direction S1 can be understood as the direction from the bottom to the top of the fin body 1, the second direction S2 can be understood as the direction in which one end of the fin body 1 extends towards the other end in the width direction, and the third direction S3 can be understood as the direction in which one end of the fin body 1 extends towards the other end in the length direction. The first direction S1, the second direction S2 and the third direction S3 are perpendicular to each other pairwise. As Figure 4 shown, the first direction S1 can be understood as the direction from bottom to top in the figure, and the second direction S2 can be understood as the direction from right to left in the figure. As Figure 5 shown, the third direction S3 can be understood as the direction from right to left in the figure. The horizontal plane S4 can be understood as the installation plane of the vehicle.

[0040] As Figures 1 to 3 shown, in the embodiment, the fin body 1 is formed in a serpentine shape. The serpentine fin body 1 includes a plurality of vertical plate members 101 and a plurality of bending portions 102. Two adjacent vertical plate members 101 are connected by a bending portion 102. Specifically, the two end portions of the vertical plate member 101 in the first direction S1 are the first end 104 and the second end 105 respectively. The vertical plate members 101 arranged in sequence along the third direction S3 are the first plate member, the second plate member, the third plate member... The vertical plate member 101 located at the side of the fin body 1 is the first plate member. The first end 104 of the first plate member is connected to the first end 104 of the second plate member through a bending portion 102. The second end 105 of the second plate member is connected to the second end 105 of the third plate member through a bending portion 102. The first end 104 of the third plate member is connected to the first end 104 of the fourth plate member through a bending portion 102, and so on, connected in sequence to form a serpentine shape. The connection portions of these plate members and the bending portion 102 are formed into an arc shape.

[0041] Specifically, to further explain the above content, the fin body 1 shaped like a snake is provided with a plurality of drainage openings 103 for discharging condensed water, thus preventing liquid water from freezing and covering the surface of the radiator, reducing the frosting phenomenon, and ensuring the heat exchange efficiency of the radiator. Specifically, the drainage openings 103 are provided at the ends of the vertical plate members 101 to facilitate the outflow of condensed water from the ends of the fin body 1. As Figure 3 and Figure 4 shown, a second included angle 3 is formed between the drainage opening 103 and the side of the vertical plate member 101, and the angle of the second included angle 3 is equal to the angle of the first included angle 2. The side of the vertical plate member 101 can be understood as Figure 4 the right side in the second direction S2 in Figure 4 . In addition, since only the structure of part of the vertical plate member 101 is shown in Figure 3 , each vertical plate member 101 is provided with four drainage openings 103, and the four drainage openings 103 are grouped in pairs. The drainage openings 103 in each pair form a second included angle 3 with the left side and the right side of the vertical plate member 101 respectively. The angle of the second included angle 3 is 10° - 60°, and the angle of the second included angle 3 is the same as the angle of the first included angle 2. When the radiator is installed obliquely, the second included angle 3 makes the drainage opening 103 closer to the vertical direction, making full use of the gravity of the condensed water droplets and enabling them to flow away quickly. In addition, the formation of the second included angle 3 can make the drainage opening 103 have a larger opening size, better break the surface tension of the droplets, decompose them into small-sized droplets, and make them easier to be carried away by the flowing air.

[0042] The fin with drainage function can quickly discharge the condensed water through the plurality of drainage openings 103 provided on the snake-shaped fin body 1, preventing the condensed water from condensing on the surface of the radiator and ensuring the heat exchange efficiency of the radiator.

[0043] Preferably, as Figures 1 to 4 shown, in the embodiment, the drainage opening 103 can be understood as protruding from the surface of the vertical plate member 101 towards one side, so that through holes are formed on the surface of the vertical plate member 101, which can break the surface tension of the droplets and enable the condensed water to be discharged quickly.

[0044] Preferably, as Figures 1 to 4 shown, in the embodiment, drainage openings 103 are provided at both ends of the vertical plate member 101 in the first direction S1 and at both ends of the vertical plate member 101 in the second direction S2, and drainage openings 103 are provided at the four corners of the vertical plate member 101. In this way, the condensed water can be quickly discharged from the four corners of the vertical plate member 101 or carried away by the air.

[0045] Preferably, as Figure 2As shown, in the embodiment, the vertical plate member 101 includes a first end 104 and a second end 105 in the first direction S1. The opening direction of the drainage opening window 103 at the first end 104 is opposite to the opening direction of the drainage opening window 103 at the second end 105. The drainage opening windows 103 with opposite opening directions can further increase the flow of condensed water and make it easier for the condensed water to be carried away by the air.

[0046] Preferably, as Figure 4 shown, in the embodiment, the size of the drainage opening window 103 in the first direction S1 is one-eighth to one-third of the size of the vertical plate member 101 in the first direction S1. In Figure 4 , h represents the size of the drainage opening window 103 in the first direction S1, H represents the size of the vertical plate member 101 in the first direction S1, h is one-eighth to one-third of H. Without damaging the overall strength of the vertical plate member 101, the size of the drainage opening window 103 is increased as much as possible so that the condensed water can be discharged more easily.

[0047] Preferably, as Figure 4 and Figure 5 shown, in the embodiment, the second included angle 3 is 10° - 60°, so as to correspond to the first included angle 2, make the drainage opening window 103 closer to the vertical direction after installation, make full use of the gravity of the condensed water droplets, and make them flow away quickly.

[0048] Preferably, as Figure 4 and Figure 5 shown, in the embodiment, the size of the drainage opening window 103 in the second direction S2 is 0.45 mm - 1.5 mm, and the size of the drainage opening window 103 in the third direction S3 is 0.1 mm - 0.3 mm. Figure 4 In Figure 5 , w is the size of the drainage opening window 103 in the second direction S2,

[0049] In the fin with drainage function, by opening a plurality of drainage opening windows on the serpentine fin body, the drainage opening windows can break the surface tension of the droplets, decompose them into small-sized droplets, so that the condensed water can be quickly discharged. At the same time, because the drainage opening windows are arranged at an angle with the vertical plate member, after the serpentine fin body is installed, the position of the drainage opening windows is closer to the vertical direction, making full use of the gravity of the condensed water droplets and making the condensed water flow away further quickly. In addition, the drainage opening windows can make the flowing air generate turbulence, increase the turbulence intensity on the air side, further increase the convective heat transfer coefficient, and thus improve the heat exchange performance of the radiator.

[0050] In addition, as Figures 6 to 8As shown, according to the second aspect of the present utility model, a frost-proof radiator is provided. The frost-proof radiator includes the fins with drainage function as described above. During the use of the frost-proof radiator, by providing fins with drainage function, the function of discharging condensed water can be realized, thereby avoiding the radiator from frosting and affecting the heat exchange efficiency. Next, in combination with Figures 6 to 8 Specifically illustrate the structure of the frost-proof radiator.

[0051] As Figures 6 to 8 shown, in the embodiment, the frost-proof radiator further includes a plurality of spaced-apart heat dissipation tubes 4 and an outer frame body. The plurality of heat dissipation tubes 4 are arranged inside the outer frame body, and the fin body 1 is arranged between two adjacent heat dissipation tubes 4 and between the heat dissipation tube 4 and the outer frame body. That is, if the number of heat dissipation tubes 4 is n, then the number of fin bodies 1 is n + 1. It can also be understood that there is a heat dissipation tube 4 between two adjacent fin bodies 1, so as to ensure the outflow of condensed water and the heat exchange efficiency.

[0052] Preferably, as Figure 6 and Figure 8 shown, in the embodiment, the bent portion 102 abuts against the heat dissipation tube 4. That is, the first end 104 and the second end 105 of the vertical plate member 101 respectively abut against two adjacent heat dissipation tubes 4 (if the fin body 1 is arranged between a heat dissipation tube 4 and the outer frame body, then the first end 104 and the second end 105 of the vertical plate member 101 respectively abut against a heat dissipation tube 4 and the frame of the outer frame body). Such a setting can ensure that when condensed water is generated in the heat dissipation tube 4, it can be discharged in time from the drainage openings 103 at both ends of the vertical plate member 101.

[0053] Preferably, as Figure 6 shown, in the embodiment, the end of the heat dissipation tube 4 is formed into an arc shape, and the top or bottom of the drainage opening 103 is close to the end of the heat dissipation tube 4. The arc-shaped end can facilitate the condensed water to flow away along the arc and avoid accumulation. Here, the top or bottom of the drainage opening 103 being close to the end of the heat dissipation tube 4 means in the same direction. For example, in the first direction S1 in Figure 6 , the bottom of the lower drainage opening 103 is close to a heat dissipation tube 4, and the top of the upper drainage opening 103 is close to a heat dissipation tube 4.

[0054] Preferably, as Figure 8 shown, in the embodiment, the outer frame body may include side plates 5, water chambers 6, main plates 7 and mounting brackets 8. The water chambers 6 are arranged on both sides of the heat dissipation tubes 4, and the water chambers 6 are communicated with the heat dissipation tubes 4 through the main plates 7, so that the cooling water can flow between the two water chambers 6. The side plates 5 are arranged between the two water chambers 6. In Figure 8In the [embodiment], the side plates 5 are arranged at the upper and lower ends of the heat dissipation tubes 4 in the embodiment, and the water chambers 6 are arranged at the left and right ends of the heat dissipation tubes 4. The mounting brackets 8 are arranged on the water chambers 6, and the outer frame body is mounted on the vehicle body of the vehicle through the mounting brackets 8. There may be four mounting brackets 8, and the four mounting brackets 8 are divided into two groups and are respectively arranged on both sides of the two water chambers 6. In addition, the side plates 5, the water chambers 6, the main fins 7 and the mounting brackets 8 may be components in the prior art, and their structures, principles and installation methods are all known to those skilled in the art and will not be limited here. In addition, the two water chambers 6 are respectively provided with a water inlet 9 and a water outlet 10 for the passage of cooling water.

[0055] The anti-frost radiator enables the condensed water generated by the heat dissipation tubes to be discharged through the drainage openings by means of the fins with drainage functions, thereby avoiding the frosting of the radiator, improving the anti-frost performance. At the same time, the drainage openings cause the flowing air to generate turbulence, increasing the turbulence intensity on the air side and further increasing the convective heat transfer coefficient, thus improving the heat exchange performance of the radiator.

[0056] In addition, according to the third aspect of the present invention, a vehicle is provided, and the vehicle includes the anti-frost radiator as described above. After the anti-frost radiator is installed on the vehicle, it can not only facilitate the layout of the whole vehicle and increase the front trunk space of the vehicle, but also avoid the frosting of the radiator and ensure the heat exchange efficiency.

[0057] Finally, it should be noted that the above embodiments are only specific implementation manners of the present application, used to illustrate the technical solutions of the present application, rather than limiting them. The protection scope of the present application is not limited thereto. Although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: any person skilled in the art within the technical scope disclosed by the present application can still modify the technical solutions recorded in the foregoing embodiments or can easily think of changes, or perform equivalent replacements on some of the technical features; and these modifications, changes or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application and should all be covered by the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
