Technical Field
[0001] This application relates to the field of vehicle cooling technology, and more particularly to a radiator and a vehicle having the same. Background Technology
[0002] In existing technologies, vehicle radiators are mainly of the tube-and-strip type, consisting of heat dissipation pipes and heat dissipation strips, with a heat exchange efficiency typically ranging from 60% to 80%. However, with technological advancements, vehicles have increasingly stringent requirements for thermal management, and the front engine compartment is becoming increasingly cramped. How to increase heat dissipation efficiency within such a confined space is an urgent problem to be solved. Utility Model Content
[0003] In view of this, the present application provides a radiator that can increase the heat exchange area and improve the heat exchange efficiency of the radiator, without increasing the volume of the heat dissipation pipe, so that the heat dissipation pipe can be arranged in a relatively narrow space to meet different usage positions.
[0004] This application also provides a vehicle that includes the aforementioned radiator.
[0005] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows:
[0006] In a first aspect, embodiments of this application provide a radiator, including a heat dissipation strip and a plurality of heat dissipation pipes. The heat dissipation strips are two in number and spaced apart along the thickness direction of the heat dissipation strips, and each heat dissipation strip has a receiving cavity inside. Each heat dissipation pipe has a heat dissipation channel inside, and the heat dissipation pipes extend along the thickness direction of the heat dissipation strips. The plurality of heat dissipation pipes are disposed between the two heat dissipation strips and arranged sequentially along the length direction of the heat dissipation strips. The heat dissipation channel communicates with the receiving cavity. The pipe wall of each heat dissipation pipe has a plurality of heat dissipation holes, and each of the plurality of heat dissipation holes is spaced apart from the inner wall of the heat dissipation pipe.
[0007] The radiator provided in this embodiment increases the heat dissipation area of the heat dissipation pipe by providing multiple heat dissipation holes on the pipe wall. This increases the heat exchange area of the radiator and improves its heat exchange efficiency. Furthermore, the multiple heat dissipation holes are spaced apart from the inner wall of the heat dissipation pipe, preventing coolant from flowing out and ensuring reliable coolant flow. Simultaneously, it eliminates the need to increase the volume of the heat dissipation pipe, allowing it to be arranged in relatively narrow spaces to meet different usage requirements.
[0008] In one possible implementation of this application, the maximum distance between any two points on the inner wall of the heat dissipation hole is d and satisfies: d≥0.5mm.
[0009] In one possible implementation of this application, the porosity of the heat dissipation pipe is A and satisfies: 85% ≤ A ≤ 95%.
[0010] In one possible implementation of this application, the thickness of the heat dissipation pipe first increases, then remains constant, and finally decreases along the width direction of the heat dissipation strip.
[0011] In one possible implementation of this application, the heat dissipation strip includes: a connecting plate, one end of which is connected to the heat dissipation pipe in the thickness direction, the connecting plate having a plurality of through holes that penetrate the connecting plate along its thickness direction and communicate with the heat dissipation channel; and a water storage section located at the end of the connecting plate opposite to the heat dissipation pipe, the water storage section having the receiving cavity for containing coolant, the receiving cavity communicating with the heat dissipation channel through the through holes.
[0012] In one possible implementation of this application, at least one of the water storage sections is provided with a drain valve for discharging coolant from the water storage section and the heat dissipation pipe.
[0013] In one possible implementation of this application, the water storage section is provided with an inlet and an outlet, both of which are connected to the receiving cavity, and both the inlet and the outlet are located on the same water storage section; or the inlet and the outlet are located on two separate water storage sections.
[0014] In one possible implementation of this application, the water storage section has a lug on the side opposite to the connecting plate, and the lug has a mounting hole.
[0015] In one possible implementation of this application, the radiator further includes: a baffle plate disposed at both ends of the radiator along the length direction of the heat dissipation strip, the baffle plate being connected to the adjacent heat dissipation pipe, the baffle plate extending along the length direction of the heat dissipation pipe and being connected to the heat dissipation strip.
[0016] Secondly, embodiments of this application provide a vehicle including the aforementioned radiator.
[0017] The vehicle provided in this application embodiment has multiple heat dissipation holes on the wall of the heat dissipation pipe. These holes increase the heat dissipation area of the heat dissipation pipe and the heat exchange area of the radiator, thereby improving the heat exchange efficiency of the radiator. Furthermore, the multiple heat dissipation holes are spaced apart from the inner wall of the heat dissipation pipe, preventing coolant from flowing out and ensuring reliable coolant flow. Simultaneously, it eliminates the need to increase the volume of the heat dissipation pipe, allowing it to be arranged in relatively narrow spaces to meet different usage requirements.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.
[0030] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.
[0031] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the positions in which the components are schematically placed in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the position of the components in the accompanying drawings.
[0032] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can mean a fixed connection, a detachable connection, or an integral part; it can mean a direct connection or an indirect connection through an intermediate medium.
[0033] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.
[0034] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description.

Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.
[0035] This application provides a vehicle. It should be noted that the vehicle in this application can refer to large vehicles, small vehicles, special-purpose vehicles, etc. For example, according to vehicle type, the vehicle in this application can be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other types of vehicles. Vehicles generally include a power source and a radiator. When the power source operates, it generates a large amount of heat. The radiator absorbs and removes this heat from the power source through internally circulating coolant, ensuring that the temperature remains within the range indicated by the power source's operating temperature.
[0036] It should be noted that the type of power source of the vehicle is not limited in the embodiments of this application. For example, for fuel vehicles, the power source can refer to fuel engines such as gasoline engines and diesel engines; for electric vehicles, the power source can refer to electric motors; for hybrid vehicles, the power source can refer to engines or electric motors; for vehicles powered by other means, the power source can refer to devices that generate power.
[0037] Based on this, refer to Figure 1 This application provides a heat sink 100, which includes a heat dissipation strip 10 and a plurality of heat dissipation pipes 20.
[0038] Reference Figure 1 and Figure 4To better illustrate the heat sink 100 provided in this embodiment, there are two heat dissipation strips 10, which are arranged along the thickness direction of the heat dissipation strips 10 (e.g., Figure 1 As shown in the first direction, the heat dissipation strips 10 are spaced apart, each containing a cavity. The heat dissipation pipes 20 have heat dissipation channels 201 inside. The heat dissipation pipes 20 extend along the thickness direction of the heat dissipation strips 10. Multiple heat dissipation pipes 20 are positioned between two heat dissipation strips 10 and along the length direction of the heat dissipation strips 10 (e.g., in the first direction shown). Figure 1 and Figure 2 The second direction shown is arranged in sequence. The heat dissipation channel 201 is connected to the receiving cavity. It can be understood that the coolant can enter the heat dissipation channel 201 from the receiving cavity. The coolant in the heat dissipation pipe 20 exchanges heat with the hotter external airflow. The coolant in the heat dissipation pipe 20 absorbs heat, thereby achieving the heat dissipation effect.
[0039] In existing technologies, vehicle radiators are mainly of the tube-and-strip type, consisting of heat dissipation pipes and heat dissipation strips, with a heat exchange efficiency typically ranging from 60% to 80%. However, with technological advancements, vehicles have increasingly stringent requirements for thermal management, and the front engine compartment is becoming increasingly cramped. How to increase heat dissipation efficiency within such a confined space is an urgent problem to be solved.
[0040] Reference Figure 3 and Figure 4 The heat pipe 20 has multiple heat dissipation holes 202 on its wall. The heat dissipation holes 202 can increase the heat dissipation area of the heat pipe 20, increase the heat exchange area of the radiator 100, and improve the heat exchange efficiency of the radiator 100. Moreover, the multiple heat dissipation holes 202 are spaced apart from the inner wall of the heat pipe 20 to prevent the coolant from flowing out of the heat pipe 20 from the heat dissipation holes 202, thus ensuring the reliability of the coolant flow.
[0041] At the same time, there is no need to increase the volume of the heat pipe 20, which allows the heat pipe 20 to be arranged in a relatively narrow space to meet different usage positions.
[0042] In addition, the material of the heat dissipation strip 10 is not limited in this embodiment, as long as it can define the receiving cavity.
[0043] Additionally, it should be noted that in this embodiment, the heat pipe 20 is an aluminum alloy component. During the manufacturing process of the heat pipe 20, metal foaming technology is used to make the aluminum alloy into a heat pipe 20 with a honeycomb-shaped pore on the outer surface, which has a larger heat dissipation area.
[0044] According to the embodiments of this application, the radiator 100 has multiple heat dissipation holes 202 on the wall of the heat dissipation pipe 20. These holes 202 increase the heat dissipation area of the heat dissipation pipe 20, thereby increasing the heat exchange area of the radiator 100 and improving its heat exchange efficiency. Furthermore, the multiple heat dissipation holes 202 are spaced apart from the inner wall of the heat dissipation pipe 20, preventing coolant from flowing out of the heat dissipation pipe 20 and ensuring reliable coolant flow. Simultaneously, it eliminates the need to increase the volume of the heat dissipation pipe 20, allowing it to be arranged in relatively narrow spaces to meet different usage requirements.
[0045] In this embodiment, the heat dissipation strip 10 is welded to the heat dissipation pipe 20. Of course, this application is not limited to this; the heat dissipation strip 10 can also be connected to the heat dissipation pipe 20 by means of adhesive or other methods.
[0046] In some embodiments of this application, the maximum distance between any two points on the inner wall of the heat dissipation hole 202 is d and satisfies: d≥0.5mm.
[0047] It is understandable that the maximum distance between any two points on the inner wall of the heat dissipation hole 202 can be 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2mm, etc., to ensure the size of the heat dissipation hole 202, to ensure the effect of the heat dissipation hole 202 in increasing the heat dissipation area of the heat pipe 20, and to ensure the heat dissipation efficiency of the heat sink 100.
[0048] In some embodiments of this application, the porosity of the heat sink 20 is A and satisfies: 85% ≤ A ≤ 95%.
[0049] Understandably, the porosity of the heat pipe 20 can be 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, or 95%. In this case, the heat dissipation efficiency of the heat pipe 20 can be increased to 90%, thereby increasing the heat dissipation efficiency of the radiator 100 and meeting the vehicle's usage requirements.
[0050] Additionally, it should be noted that the porosity of the heat pipe 20 refers to the ratio of the total volume of all heat dissipation holes 202 in a single heat pipe 20 to the volume of the pipe wall of the heat pipe 20.
[0051] In some embodiments of this application, reference is made to Figure 3 Along the width direction of the heat dissipation strip 10 (e.g. Figure 2 As shown in the third direction, the thickness of the heat pipe 20 first increases, then remains unchanged, and finally decreases, so that the heat pipe 20 is formed into a flat pipe. Under the same volume, the surface area of the flat pipe in contact with the air is greater than that of the round pipe, thereby improving the heat dissipation efficiency of the heat pipe 20.
[0052] The thinner flat tubes can be densely arranged inside the radiator 100, making the overall size of the radiator 100 smaller and suitable for compact layouts in places such as the engine compartment of a vehicle.
[0053] In this embodiment, the width direction of the heat dissipation strip 10 can be the same as the flow direction of the airflow. The airflow to be heat exchanged can first contact the part of the heat dissipation tube 20 with a smaller thickness, then gradually contact the heat dissipation tube 20 with a more uniform thickness, and finally contact the part of the heat exchange tube with a gradually decreasing thickness. The airflow gradually leaves the heat exchange tube, and the process of the airflow passing through the heat exchange tube is relatively smooth, avoiding noise when the airflow comes into contact with the heat exchange tube.
[0054] In this embodiment, along the width direction of the heat dissipation strip 10, the two ends of the heat dissipation pipe 20 are opposite arc surfaces, and the contact between the arc surfaces and the airflow is relatively gentle.
[0055] In some embodiments of this application, reference is made to Figure 1 and Figure 2 The heat dissipation strip 10 includes a connecting plate 1 and a water storage section 2, wherein the thickness direction of the connecting plate 1 is (e.g., ...). Figure 1 One end of the connecting plate 1 (shown in the first direction) is connected to the heat dissipation pipe 20. The connecting plate 1 has multiple through holes 11. The through holes 11 penetrate the connecting plate 1 along the thickness direction of the connecting plate 1 and are connected to the heat dissipation channel 201. The water storage part 2 is located at the end of the connecting plate 1 away from the heat dissipation pipe 20. The water storage part 2 has a receiving cavity for containing coolant. The receiving cavity is connected to the heat dissipation channel 201 through the through holes 11.
[0056] Understandably, the coolant in the cavity enters the heat dissipation channel 201 through the through hole 11, realizing heat exchange between the coolant and the surrounding airflow, and ensuring the heat dissipation effect of the radiator 100.
[0057] Meanwhile, the connecting plate 1 can support the heat pipe 20, increasing the reliability of the position of the heat pipe 20.
[0058] In some embodiments of this application, reference is made to Figure 1 and Figure 2 At least one water storage section 2 is equipped with a drain valve 21 for draining the coolant in the water storage section 2 and the heat dissipation pipe 20. When the radiator 100 is repaired or replaced, the coolant in the water storage section and the heat dissipation pipe 20 can be drained through the drain valve 21 before the operation is carried out, so as to avoid the coolant from splashing onto the body of the maintenance personnel during the maintenance or replacement of the radiator 100 and avoid injury to the maintenance personnel.
[0059] In some embodiments of this application, reference is made to Figure 1The water storage section 2 is provided with an inlet 22 and an outlet 23. Both the inlet 22 and the outlet 23 are connected to the receiving cavity. The inlet 22 and the outlet 23 are both located on the same water storage section 2; or the inlet 22 and the outlet 23 are located on two different water storage sections 2.
[0060] It is understandable that the inlet 22 and the outlet 23 are both located on the same water storage section 2; or the inlet 22 and the outlet 23 are located on two different water storage sections 2.
[0061] When both the inlet 22 and the outlet 23 are located on the same water storage section 2, the coolant enters the receiving cavity of one water storage section 2 from the inlet 22, then enters different heat dissipation channels 201, and can flow between the heat dissipation channels 201 and the two water storage sections 2, and finally flows out of the radiator 100 from the outlet 23, thus realizing the circulation of coolant in the radiator 100.
[0062] When the inlet 22 and outlet 23 are respectively provided on the two water storage sections 2, the coolant enters the receiving cavity of one water storage section 2 from the inlet 22, then enters different heat dissipation channels 201, and can flow between the heat dissipation channels 201 and the two water storage sections 2, and finally flows out of the radiator 100 from the outlet 23, realizing the circulation of coolant in the radiator 100.
[0063] In some embodiments of this application, reference is made to Figure 1 The water storage section 2 has a lug 24 on the side opposite to the connecting plate 1. The lug 24 has a mounting hole 241, which facilitates the installation of the radiator 100 and makes the connection between the radiator 100 and other parts of the vehicle simpler and more reliable.
[0064] In this embodiment, the radiator 100 is connected to other components by fasteners, which can be inserted into the mounting holes 241, making the connection between the radiator 100 and other components simpler and more reliable.
[0065] In some embodiments of this application, reference is made to Figure 1 The radiator 100 also includes a baffle 30, which is disposed along the length of the heat dissipation strip 10 of the radiator 100 (e.g., Figure 1 and Figure 2 At both ends of the second direction shown, the baffle 30 is connected to the adjacent heat sink 20, and the baffle 30 is along the length direction of the heat sink 20 (e.g., in the second direction shown). Figure 1 The first direction shown extends and connects to the heat dissipation strip 10. The baffle 30 can help support the heat dissipation pipe 20 and the heat dissipation strip 10, prevent the heat dissipation pipe 20 and the heat dissipation strip 10 from separating, and increase the overall strength of the heat sink 100.
[0066] The vehicle according to an embodiment of this application includes the radiator 100 described above.
[0067] According to the vehicle embodiment of this application, by providing multiple heat dissipation holes 202 on the wall of the heat dissipation pipe 20, the heat dissipation holes 202 can increase the heat dissipation area of the heat dissipation pipe 20, increase the heat exchange area of the radiator 100, and improve the heat exchange efficiency of the radiator 100. Furthermore, the multiple heat dissipation holes 202 are spaced apart from the inner wall of the heat dissipation pipe 20, preventing coolant from flowing out of the heat dissipation pipe 20 from the heat dissipation holes 202, thus ensuring the reliability of coolant flow. At the same time, it does not require increasing the volume of the heat dissipation pipe 20, allowing the heat dissipation pipe 20 to be arranged in a relatively narrow space to meet different usage requirements.
[0068] The sequence numbers of the embodiments in this application are for descriptive purposes only and do not represent the superiority or inferiority of the embodiments. The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made based on the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
