Description

Technical Field

[0001] This application relates to the field of heat exchange device technology, and more specifically, to a radiator. Background Technology

[0002] With the rapid development of new energy vehicles, radiators, as key components, directly affect the performance and safety of vehicles. During operation, radiators are easily damaged or have reduced efficiency due to impacts from foreign objects such as flying stones on the road.

[0003] To reduce the impact of foreign objects on the radiator, a stone guard is usually installed in front of the radiator. However, there is a gap between the stone guard and the radiator, and some foreign objects can still enter between the stone guard and the radiator through the gap and cannot be easily discharged. If the foreign objects are not cleaned in time, they may block the heat dissipation surface of the radiator or damage the heat dissipation structure, causing the radiator's performance to decrease. In severe cases, they may damage the radiator and cause it to leak, threatening driving safety. Utility Model Content

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0028] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application.

[0031] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0032] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0033] During vehicle operation, radiators are exposed to impacts from external objects such as flying stones, branches, or leaves. While existing stone deflectors can effectively protect against larger objects, a gap typically exists between the stone deflector and the radiator, which can become a critical entry point for debris. If an object falls into this gap, it can not only affect the radiator's normal performance but also damage the cooling structure and even threaten driving safety. Therefore, effectively preventing debris from entering the space between the stone deflector and the radiator through this gap is a pressing technical problem that needs to be solved.

[0034] Please refer to Figures 1-5 This application provides a radiator comprising a radiator body 100, a retainer 200, and a sealing element 210. The retainer 200 has a first end and a second end along the width direction of the radiator body 100. The first end of the retainer 200 is connected to the radiator body 100, thereby achieving overall fixation of the retainer 200; however, a gap 300 exists between the second end of the retainer 200 and the radiator body 100, which is the main path for potential foreign objects to enter. To solve this problem, a sealing element 210 is provided within this gap 300. With this design, the sealing element 210 can fit tightly against the gap 300 between the retainer 200 and the radiator body 100, forming an effective physical barrier, thereby significantly reducing the possibility of foreign objects entering.

[0035] It should be noted that the stone retainer 200 is roughly rectangular. Since there is a gap 300 between the second end of the stone retainer 200 and the radiator body 100, placing the seal 210 here will not interfere with the function of the radiator body 100, and can make full use of the existing spatial layout to achieve a good protective effect.

[0036] By installing a seal 210 at the gap 300 between the rockfall shield 200 and the radiator body 100, the technical problem of foreign objects entering the space between the rockfall shield 200 and the radiator body 100 through the gap 300 is effectively solved. This design not only reduces maintenance frequency and repair costs, but also improves the overall reliability and safety of the radiator. When the radiator is used in a vehicle, it also provides a strong guarantee for the efficient and stable operation of the vehicle.

[0037] In this embodiment, the radiator body 100 includes a plurality of flat tubes 110, which are spaced apart along the width direction of the radiator body 100, and the sealing element 210 is a sealing strip.

[0038] In an optional embodiment, one side of the sealing strip is fixedly connected to the stone retainer 200, and the other side of the sealing strip abuts against or extends into the flat tube 110 between two adjacent flat tubes 110.

[0039] The stone retainer 200 covers at least part of the flat tube 110. The second end of the stone retainer 200 is located between two adjacent flat tubes 110. The other side of the sealing strip abuts against or extends into the narrower side of the flat tube 110, so that foreign objects cannot enter between the stone retainer 200 and the part of the flat tube 110 covered by the stone retainer 200, thereby reducing the damage to the part of the flat tube 110 caused by foreign objects and the impact on heat dissipation.

[0040] In another alternative embodiment, the sealing strip is fixed between two adjacent flat tubes 110, and one side of the sealing strip abuts or is fixedly connected to the stone retainer 200.

[0041] The stone retainer 200 is provided with multiple grids, and the sealing strip can be a mesh structure, which is filled in multiple grids of the stone retainer 200. Alternatively, the number of sealing strips can be multiple, and multiple sealing strips are filled in multiple grids of the stone retainer 200 respectively. For example, the sealing strips are glued or snapped into the grids. The multiple sealing strips can be set separately or as a whole.

[0042] In this embodiment, the sealing strip is made of foam material. It should be noted that the foam material specifically includes materials with softness, elasticity, and a certain degree of compression recovery. These material properties allow the sealing strip to effectively fit into the gap 300 between the retainer 200 and the radiator body 100, thereby achieving a reliable blocking effect. At the same time, due to the lightweight nature of the foam material itself, it will not place an additional burden on the overall structure of the radiator, nor will it significantly affect the heat dissipation performance due to long-term use.

[0043] Furthermore, the sealing strip is fixedly connected to the stone retainer 200 by adhesive bonding. Specifically, this bonding method can be achieved using adhesive, which ensures that the sealing strip is firmly attached to the second end of the stone retainer 200, preventing the sealing strip from loosening or shifting due to vibration during vehicle operation or other external factors.

[0044] By selecting foam material and using adhesive to fix the sealing strip to the stone retainer 200, it can not only effectively prevent foreign objects from entering the space between the stone retainer 200 and the radiator body 100 through the gap 300, but also take into account the convenience of installation and the reliability of long-term use.

[0045] In other embodiments, the sealing strip is made of rubber and can be fixed to the stone retainer 200 by vulcanization or bonding.

[0046] In this embodiment, along the width direction of the radiator body 100, the radiator body 100 has a top end and a bottom end, the first end of the retainer 200 is connected to the bottom end of the radiator body 100, and the second end of the retainer 200 is located between the top end and the bottom end of the radiator body 100.

[0047] It should be noted that when foreign objects reach the radiator, they generally only impact a portion of the radiator. Therefore, the retaining cover 200 does not need to cover the entire radiator body 100. The second end of the retaining cover 200 only needs to be positioned between the top and bottom ends of the radiator body 100, so that the retaining cover 200 covers a portion of the radiator body 100. This reduces the amount of material used in the retaining cover 200 and also mitigates its impact on the radiator's heat dissipation performance.

[0048] Optionally, the second end of the shield 200 is located in the middle of the radiator body 100. Since external foreign objects generally only impact the area from the bottom to the middle of the radiator body 100, it is sufficient to set the second end of the shield 200 in the middle of the radiator body 100.

[0049] In this embodiment, a fixing support 120 is provided at the bottom end of the radiator body 100. This fixing support 120 not only provides support but also provides a stable mounting base for the retaining wall 200. Meanwhile, a buckle 220 is provided at the first end of the retaining wall 200, and a matching snap-fit ​​hole 121 is provided on the fixing support 120. Specifically, the engagement of the buckle 220 and the snap-fit ​​hole 121 allows for a quick and secure connection between the retaining wall 200 and the radiator body 100. When the buckle 220 snaps into the snap-fit ​​hole 121, the assembly of the retaining wall 200 is completed.

[0050] It should be noted that the snap fastener 220 refers to a mechanical structure with elastic deformation capability, which can overcome certain resistance during assembly and then be inserted into the snap-fit ​​hole 121, and remain in a locked state in the snap-fit ​​hole 121 through its own restoring force. The snap-fit ​​hole 121 refers to a hole specially opened on the fixed support member 120 to accommodate the snap fastener 220, and its shape and size are adapted to the snap fastener 220 to ensure that a reliable connection can be formed between the two.

[0051] Optionally, the stone retainer 200 is provided with multiple buckles 220 at intervals along its own length, and the fixed support 120 is provided with multiple snap holes 121. The multiple buckles 220 and the multiple snap holes 121 are matched one-to-one, so that the stone retainer 200 can be stably fixed to the fixed support 120. The fixed support 120 can be U-shaped.

[0052] In this embodiment, along the length of the radiator body 100, a manifold 130 is provided on both sides of the radiator body 100, and at least one manifold 130 is provided with a guide structure 131 for guiding the retaining cover 200 along the width of the radiator body 100.

[0053] It should be noted that the length direction of the radiator body 100 is consistent with the length direction of the retaining cover 200, and the width direction of the radiator body 100 is consistent with the length direction of the manifold 130. One of the manifolds 130 is provided with a guide structure 131, or both manifolds 130 are provided with a guide structure 131. The guide structure 131 can guide the retaining cover 200 along the width direction of the radiator body 100. During the installation of the retaining cover 200, the retaining cover 200 can be assembled along the width direction of the radiator body 100 under the guidance of the guide structure 131, and it is not easy for the retaining cover 200 to be misaligned, thereby ensuring that the retaining cover 200 can effectively protect the radiator body 100.

[0054] In this embodiment, the side of the retaining cover 200 is provided with an extension plate 230 extending toward the collector pipe 130. The extension plate 230 is provided with a guide groove 231 along the width direction of the radiator body 100. The guide structure 131 cooperates with the guide groove 231.

[0055] The stone retainer 200 has an extension plate 230 extending toward the collector pipe 130 on its side along its own length direction. The extension plate 230 has a guide groove 231 that cooperates with the guide structure 131. Through the cooperation between the guide structure 131 and the guide groove 231, the stone retainer 200 is not easy to deviate along the length direction of the radiator body 100 during the assembly process.

[0056] Please refer to Figure 6The guide structure 131 includes an integrally formed base 1311 and a bent plate 1312. The base 1311 is connected to the manifold 130. The bent plate 1312 extends along the width direction of the radiator body 100 after being bent relative to the base 1311. There is a slot 1313 between the bent plate 1312 and the base 1311 for the extension plate 230 to extend into, and the bent plate 1312 cooperates with the guide groove 231.

[0057] The bent plate 1312 extends from the top of the base 1311 and extends along the width direction of the heat sink body 100 toward the top of the heat sink body 100. The end of the bent plate 1312 away from the base 1311 is a free end.

[0058] During the assembly process, the extension plate 230 on the side of the stone retainer 200 extends into the slot 1313, and the bending plate 1312 cooperates with the guide groove 231, so that the stone retainer 200 is not easy to shift along the length direction of the radiator body 100, and the stone retainer 200 is not easy to shift along the thickness direction of the radiator body 100. When the extension plate 230 is inserted into the inside of the slot 1313, the extension plate 230 abuts against the bending point of the bending plate 1312, accurately defining the installation position of the stone retainer 200.

[0059] In addition, a guide slope 1314 is provided at the end of the bending plate 1312 away from the base 1311. The provision of the guide slope 1314 facilitates the extension plate 230 to quickly extend into the bayonet 1313, thereby improving the assembly efficiency of the stone retainer 200.

[0060] In this embodiment, a radiator body 100 is provided with an air guide shroud 140, the air guide shroud 140 is provided with an air inlet 141, and the first end of the baffle 200 is closer to the air inlet 141 than the second end.

[0061] Under normal operating conditions, foreign objects from outside the radiator will enter through the air inlet 141 of the air guide shroud 140. These foreign objects can generally only impact a portion of the surface of the radiator body 100. Therefore, the baffle 200 only needs to cover this portion of the radiator body 100. For example, if the second end of the baffle 200 is located in the middle of the radiator body 100, some foreign objects will reach the second end of the baffle 200. At this time, the sealing strip will prevent these foreign objects from entering the area covered by the baffle 200 through the gap 300 between the second end of the baffle 200 and the radiator body 100, thus providing effective protection for the radiator.

[0062] In summary, this application provides a radiator comprising a radiator body 100 and a rockfall shield 200. By providing a sealing strip at the second end of the rockfall shield 200, the technical problem of foreign objects entering the space between the rockfall shield 200 and the radiator body 100 through the gap 300 is effectively solved. This design not only reduces maintenance frequency and repair costs but also improves the overall reliability and safety of the radiator. When applied to vehicles, the radiator provides strong support for the efficient and stable operation of the vehicle.

[0063] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
