Description

Technical Field

[0001] This utility model relates to the field of automotive radiator technology, and in particular to a radiator hot air backflow prevention device. Background Technology

[0002] During the operation of a coal truck, the engine generates a significant amount of heat. This heat needs to be effectively dissipated through the radiator to ensure normal engine operation and extend its service life. Therefore, the radiator plays a crucial role in the vehicle's cooling system, and its heat dissipation directly affects the cooling efficiency of the vehicle's water and oil circuits.

[0003] Currently, radiators are typically installed inside the engine hood to ensure their protection in harsh working environments, and the hood has openable and closable side doors for sealing and protecting the radiator. Patent CN219605392U discloses a hot air backflow prevention structure for a loader radiator, which prevents hot air backflow by attaching sponge around the radiator as much as possible. However, relying solely on sponge to block hot air may cause some problems.

[0004] First, the sponge, exposed to high temperatures for extended periods, may age or become damaged over time, gradually losing its function and affecting the radiator's heat dissipation. If part of the sponge is damaged, the entire sponge may need to be replaced, increasing maintenance costs. Second, in harsh working environments, such as on bumpy roads, the sponge around the radiator can easily detach due to vehicle movement. Once the sponge detaches, hot air can flow back into the radiator's air intake through the gaps, significantly reducing the radiator's heat dissipation efficiency. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a radiator hot air backflow prevention device. To achieve the above objective, this utility model provides a radiator hot air backflow prevention device, including a housing and a baffle mechanism. The housing includes a shroud body, and the radiator is installed inside the shroud body. A guide shroud extending towards the radiator exhaust port is provided around the shroud body. The baffle mechanism includes multiple baffle blocks, which are installed between the radiator and the guide shrouds, forming a heat dissipation channel around the radiator.

[0006] Furthermore, the contact surface between the wind deflector and the air guide is provided with a first fixing member, and the wind deflector and the air guide are connected through the first fixing member.

[0007] Furthermore, the wind deflector includes a wind deflector body, a groove, and a boss, and multiple wind deflectors are connected by the groove and the boss.

[0008] Furthermore, the anti-backflow device also includes a limiting unit, which is evenly distributed around the hood body. The limiting unit includes multiple snap-fit ​​components, one end of which is rotatably connected to the hood body, and the other end of which abuts against the wind deflector.

[0009] Furthermore, the baffle mechanism also includes a fixing frame and a guide plate. One end of the fixing frame is fixedly connected to the air guide shroud, and the other end is rotatably connected to the guide plate.

[0010] Furthermore, the fixing frame includes a first support rod and a second support rod. One end of the first support rod is connected to the air guide cover, and the other end is slidably sleeved with the second support rod. The second support rod can slide up and down or be fixed relative to the first support rod.

[0011] Furthermore, the baffle mechanism also includes an angle adjustment unit, which is used to adjust the angle between the guide plate and the second support rod.

[0012] Furthermore, the windbreak block is a rubber block or a sponge block.

[0013] Furthermore, the housing also includes a side door panel installed at the outer air outlet of the radiator, and the side door panel is detachably connected to the main body of the casing.

[0014] Furthermore, the side door panel is provided with ventilation holes.

[0015] The radiator hot air backflow prevention device provided by this utility model has at least one of the following beneficial technical effects:

[0016] 1. By installing multiple baffles around the air guide and radiator, the airtightness between the two is ensured, effectively preventing the backflow of hot air from the radiator. Furthermore, the multiple baffle design means that if a baffle becomes deformed or ages, it is not necessary to replace the entire baffle, thus reducing the maintenance cost of the hot air backflow prevention device.

[0017] 2. By setting the first fixing part and the snap-fit ​​part, the connection between the wind deflector and the wind guide is made more secure.

[0018] 3. Adjacent windbreak blocks can be connected as a whole by grooves and protrusions, ensuring the stability of the connection between adjacent windbreak blocks.

[0019] 4. By setting up a fixing bracket and a guide plate, the abutment design between the guide plate and the baffle block can further secure the baffle block, preventing it from falling off. At the same time, the guide plate effectively guides airflow, improving the radiator's heat dissipation efficiency. Furthermore, the angle and height of the fixing bracket and guide plate are adjustable, making it suitable for radiators of different sizes and types. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0027] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure).

[0030] Furthermore, the technical solutions of the various embodiments of this application can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this application.

[0031] like Figure 1 and Figure 2 As shown in the figure, a radiator hot air backflow prevention device disclosed in this utility model embodiment includes a housing 1 and a baffle mechanism. The housing 1 includes a shroud body 101, and the radiator 3 is installed inside the shroud body 101. The shroud body 101 is provided with a guide shroud 4 extending towards the exhaust port of the radiator 3. The baffle mechanism includes a plurality of baffle blocks 201, which are installed between the radiator 3 and the guide shroud 4. The plurality of baffle blocks 201 surround the radiator 3 to form a heat dissipation channel.

[0032] In the anti-backflow device for the radiator 3 of this utility model, the shroud body 101 provides installation space for the radiator 3, and the air guide shroud 4 can be detachably connected to the shroud body 101. By setting wind baffles 201 around the air guide shroud 4 and the radiator 3, the gap between the radiator 3 and the air guide shroud 4 can be filled, ensuring the sealing effect between the two. At the same time, the wind baffles 201 are designed in the form of multiple blocks. When one wind baffle 201 deforms or ages due to long-term use, it will not negatively affect the sealing performance of other wind baffles 201. The staff only needs to replace the aged or damaged wind baffles 201, without replacing the entire baffle mechanism. This design not only greatly reduces maintenance costs but also improves maintenance efficiency, making the maintenance of the entire heat dissipation system simpler and more economical. In addition, since there are different temperatures and wind pressures around the radiator 3, by setting the wind baffles 201 as multiple small blocks, it is convenient for the staff to set wind baffles 201 of different specifications at different positions on the radiator 3, thereby ensuring the sealing effect of the anti-backflow device.

[0033] It should be noted that the present invention does not limit the type of windbreak block 201. In one embodiment, the windbreak block 201 is a rubber block or a sponge block.

[0034] like Figure 3 As shown, in a preferred embodiment of this utility model, a first fixing member 5 is provided on the contact surface between the wind deflector 201 and the air guide shroud 4, and the wind deflector 201 and the air guide shroud 4 are connected by the first fixing member 5. The wind deflector 201 can be fixedly connected to the air guide shroud 4 by the fixing member, and multiple wind deflectors 201 are formed as a whole around the radiator 3 by the fixing member.

[0035] It should be noted that the present invention does not limit the type of the first fixing member 5. In one embodiment, the first fixing member 5 is a magnetic member.

[0036] In a preferred embodiment of the present invention, the wind deflector 201 includes a wind deflector body 211, a groove 212 and a boss 213, and multiple wind deflectors 201 are connected by the groove 212 and the boss 213.

[0037] like Figure 3 As shown, by setting the wind deflector 201 to a snap-fit ​​connection, it is ensured that multiple wind deflectors 201 can be tightly combined to form a complete wind deflector structure, making the connection between adjacent wind deflectors 201 more stable; moreover, this snap-fit ​​connection method also simplifies the installation process for workers, improves installation efficiency, and makes it convenient for workers to quickly disassemble and replace the wind deflector 201.

[0038] In a preferred embodiment of this invention, the anti-backflow device further includes limiting units. These limiting units are evenly distributed around the hood body 101. Each limiting unit includes multiple snap-fit ​​members 601. One end of each snap-fit ​​member 601 is rotatably connected to the hood body 101, and the other end abuts against the wind deflector block 201. By providing the snap-fit ​​members 601, the position of the wind deflector block 201 can be further limited, thereby firmly fixing the wind deflector block 201 around the hood body 101 and preventing displacement of the wind deflector block 201 during use, which would affect the anti-backflow effect of the hot air.

[0039] like Figure 4 As shown, in a preferred embodiment of this utility model, the baffle mechanism includes a fixing frame 202 and a guide plate 203. One end of the fixing frame 202 is fixedly connected to the air guide cover 4, and the other end is rotatably connected to the guide plate 203. The guide plate 203 is located between the baffle block 201 and the radiator 3, and the guide plate 203 abuts against the baffle block 201. By setting the baffle assembly, the baffle block 201 can be fixed again, avoiding the possibility of the baffle block 201 falling off. Furthermore, the design of the guide plate 203 not only prevents backflow but also effectively guides the airflow, allowing the air to pass through the radiator 3 more smoothly, thus improving the heat dissipation efficiency. The abutting design between the guide plate 203 and the baffle block 201 ensures the tightness of the structure, reduces air leakage, and further improves the heat dissipation performance.

[0040] In a preferred embodiment of the present invention, the fixing frame 202 includes a first support rod 221 and a second support rod 222. One end of the first support rod 221 is connected to the air guide cover 4, and the other end is slidably sleeved with the second support rod 222. The second support rod 222 can slide up and down or be fixed relative to the first support rod 221.

[0041] like Figure 4 As shown, by setting the first support rod 221 and the second support rod 222 to be sleeved together, the operator can adjust the height of the fixing frame 202 according to actual needs. When the hot air generated by the radiator 3 is strong, the position of the second support rod 222 relative to the first support rod 221 can be slid to bring the guide plate 203 closer to the wind deflector 201, thereby more effectively blocking the backflow of hot air. Conversely, when the hot air intensity is low, the position of the guide plate 203 can be adjusted appropriately to reduce interference with the heat dissipation effect of the radiator 3. In addition, the sliding sleeve design of the second support rod 222 and the first support rod 221 also facilitates installation and maintenance, improving the practicality and flexibility of the entire anti-backflow device.

[0042] In a preferred embodiment of this utility model, the baffle mechanism further includes an angle adjustment unit 7, through which the guide plate 203 and the second support rod 222 are connected. The angle adjustment unit 7 allows for flexible adjustment of the angle of the guide plate 203 to adapt to different working scenarios and needs, ensuring a closer fit between the guide plate 203 and the windbreak block 201 and radiator 3. Furthermore, the angle adjustment unit 7 possesses a certain degree of durability and stability, maintaining stable performance during long-term use, thereby ensuring the reliability and durability of the entire anti-backflow device.

[0043] It should be noted that the present invention does not limit the type of the angle adjustment unit 7. In one embodiment, the angle adjustment unit 7 is a screw adjustment mechanism, specifically, a screw adjustment mechanism is installed between the guide plate 203 and the second support rod 222.

[0044] In a preferred embodiment of the present invention, the outer casing 101 further includes a side door panel 102 installed at the air outlet on the outside of the radiator 3. The side door panel 102 is detachably connected to the casing body 101, and the side door panel 102 is provided with an exhaust hole 8.

[0045] The side door panel 102 protects the radiator 3 from foreign objects entering during operation. Simultaneously, the side door panel 102 is detachably connected to the main body 101, allowing for easy opening and closing to facilitate maintenance and cleaning of the radiator 3. The ventilation holes 8 in the side door panel 102 improve heat dissipation efficiency, ensuring timely exhaust of hot air.

[0046] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the inventive concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
