[0002] The main function of preventing hot air backflow is to prevent hot air that has already undergone heat exchange in the engine compartment from flowing back to the radiator and participating in heat exchange again. The radiator belongs to the automotive cooling system. In the engine water cooling system, the radiator consists of three parts: the inlet chamber, the outlet chamber, the main fins, and the radiator core.

[0003] Chinese utility model patent with publication number CN210165787U is entitled "Anti-Hot Air Backflow Device and Radiator for Automobile Radiator".

[0011] As a further embodiment of the present invention: the limiting component includes a limiting rod, and stabilizing plates are fixedly installed at both ends of the mounting frame. The limiting rod is slidably installed through the stabilizing plate. A baffle is fixedly installed at one end of the limiting rod near the air duct. A third spring is fixedly installed on the side of the baffle away from the air duct. A limiting hole is opened at the corresponding position of the limiting rod on the air duct.

[0012] As a further embodiment of the present invention: the end of the third spring away from the baffle is fixedly installed on the stabilizing plate, the third spring is nested on the outer surface of the limiting rod, and calibration plates are fixedly installed on both sides of the mounting frame near the air duct.

[0013] An automotive radiator includes the aforementioned vehicle body heat-resistant air recirculation mechanism, and also includes a radiator body. The radiator body is provided with a guide frame, and a sliding groove is formed in the guide frame. A filter plate is slidably installed in the sliding groove, and a locking assembly is provided on the radiator body.

[0014] As a further embodiment of the present invention: a fixing plate is rotatably mounted on the side of the guide frame near the filter plate, and a placement plate is fixedly mounted on the bottom of the radiator body.

[0015] As a further aspect of the present invention: the engaging assembly includes an engaging plate, two support plates are fixedly installed on the radiator body, a bidirectional screw is rotatably installed between the two support plates, the engaging plate is threaded through the bidirectional screw, two mounting plates are fixedly installed on the side of the guide frame near the radiator body, engaging grooves are formed on the two mounting plates, and a knob is fixedly installed at one end of the bidirectional screw that is threaded through one of the support plates.

[0017] The beneficial effects of this invention are:

[0018] (1) By starting the exhaust fan, the exhaust fan drives the hot air to blow onto the air guide plate and blows open the sealing strip. At the same time, the air guide plate is squeezed by the wind force to squeeze the first spring, and then the hot air is discharged into the air guide pipe. The hot air is discharged through the dust screens on both ends of the air guide pipe, which facilitates the discharge of hot air and prevents the hot air from flowing back. This is beneficial to improving the efficiency of the device and improving the heat dissipation capacity of the device.

[0019] (2) When the vehicle is moving, the force of the bumps causes the sliding frame to slide within the mounting frame. At the same time, the sliding frame squeezes the telescopic rod and the second spring. The second spring is frequently compressed and reset, which makes it easy for the sliding frame to drive the cleaning plate to scrape back and forth on the dust screen. This makes it easy to clean the dust adsorbed on the dust screen, which is convenient to operate and use. It is beneficial to improve the dust cleaning ability of the device and to extend the service life of the device.

[0020] (3) The locking assembly uses the guide frame to hold the heat sink body on both sides, then pushes the guide frame to the placement plate, and then turns the knob to drive the bidirectional screw to rotate. At the same time, the bidirectional screw drives the locking plate to slide on the heat sink body and inserts the locking plate into the locking groove in the mounting plate. This makes it easy to lock and fix the position of the guide frame, which is convenient for installation and disassembly. This helps to improve the safety and stability of the device, facilitates operation and use, and improves the heat dissipation capacity of the device. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figure 1 - Figure 5As shown, this invention is a heat-prevention mechanism for a vehicle body, comprising an exhaust pipe 2, with a guide pipe 3 fixedly installed at one end of the exhaust pipe 2. The guide pipe 3 facilitates the guidance of hot air to another space, minimizing the possibility of hot air flowing back into the vehicle body. Dustproof nets 4 are fixedly installed at both ends of the guide pipe 3, serving to prevent dust from being carried back into the guide pipe 3 by the air. An exhaust fan 8 is fixedly installed on the inner wall of the exhaust pipe 2, facilitating the extraction of hot air from the radiator body 1, which helps improve the heat dissipation efficiency of the radiator body 1. Air guide plates 9 and first springs 10 are rotatably installed on the inner walls on both sides of the exhaust pipe 2. The air guide plates 9, under the elastic action of the first springs 10, prevent the expelled hot air from flowing back, and the first springs 10 also serve to drive the air guide plates 9 to elastically return to their original position. Sealing strips 11 are fixedly installed on the corresponding sides of the two air guide plates 9, serving to seal and prevent backflow. Two first springs 10 are fixedly mounted on the air guide plate 9 at their corresponding ends. A heat dissipation aluminum fin 16 is fixedly mounted on the side of the air guide plate 9 away from the exhaust pipe 2. The exhaust fan 8 exhausts hot air into the air guide pipe 3. The heat remains on the air guide pipe 3, causing it to become hot and potentially burn the staff. The heat dissipation aluminum fin 16 helps to dissipate heat from the air guide pipe 3, minimizing the risk of burns. Cleaning components 5 and limiting components 6 are provided at both ends of the exhaust pipe 2. When using the device, the exhaust fan 8 is first turned on, causing it to blow hot air onto the air guide plate 9 and open the sealing strip 11. At the same time, the air guide plate 9 is compressed by the airflow, causing the first springs 10 to be in a compressed state. Then, the hot air is exhausted into the air guide pipe 3 and passes through the dustproof nets 4 at both ends of the air guide pipe 3 to facilitate the removal of hot air and prevent hot air backflow. This improves the efficiency of the device and enhances its heat dissipation capacity.

[0032] Please see Figure 1 and Figure 2 As shown, the cleaning component 5 includes a cleaning plate 55. Mounting frames 51 are fixedly installed on both ends of the exhaust pipe 2. A sliding frame 52 is slidably installed inside the mounting frame 51. The cleaning plate 55 is fixedly installed on the inner wall of the sliding frame 52. The sliding frame 52 drives the cleaning plate 55 to slide on the mounting frame 51 to clean the dust. The cleaning plate 55 is tilted at 45 degrees and slides against the dustproof net 4. An elastic unit is provided inside the mounting frame 51. The cleaning plate 55 plays the role of scraping off the adsorbed dust on the dustproof net 4.

[0033] Please see Figure 1 and Figure 2As shown, the elastic unit includes a second spring 54. Telescopic rods 53 are fixedly installed on the inner walls of both ends of the mounting frame 51. The telescopic rods 53 limit and stabilize the position of the sliding frame 52 within the mounting frame 51. One end of the telescopic rod 53 away from the mounting frame 51 is fixedly installed on the sliding frame 52. The second spring 54 is nested on the outer surface of the telescopic rod 53. The second spring 54 drives the sliding frame 52 to elastically reset. Both ends of the second spring 54 are fixedly installed on the sliding frame 52 and the mounting frame 51, respectively. A collection box 56 is fixedly installed at the bottom of the mounting frame 51. The collection box 56 serves to collect dust. When the device is in use, the vehicle bumps and jolts as it moves, and the force of the bumps causes the sliding frame 52 to slide within the mounting frame 51. At the same time, the sliding frame 52 squeezes the telescopic rod 53 and the second spring 54, putting the telescopic rod 53 and the second spring 54 in a compressed state. The second spring 54 is frequently compressed and reset, which makes it easier for the sliding frame 52 to drive the cleaning plate 55 to scrape back and forth on the dustproof net 4, making it easier to clean the dust adsorbed on the dustproof net 4. This makes the device easy to operate and use, improves the dust cleaning ability of the device, and helps to extend the service life of the device.

[0034] Please see Figure 1 and Figure 3 As shown, the limiting component 6 includes a limiting rod 62. Stabilizing plates 61 are fixedly installed at both ends of the mounting frame 51. The stabilizing plates 61 serve to fix the limiting rod 62. The limiting rod 62 is slidably installed on the stabilizing plates 61. A baffle 63 is fixedly installed at the end of the limiting rod 62 near the air duct 3. The baffle 63 serves to limit the third spring 64. The third spring 64 is fixedly installed on the side of the baffle 63 away from the air duct 3. A limiting hole 65 is opened at the corresponding position of the limiting rod 62 in the air duct 3. The limiting rod 62 is inserted into the limiting hole 65, which serves to limit and fix the mounting frame 51.

[0035] Please see Figure 1 and Figure 3 As shown, the end of the third spring 64 furthest from the baffle 63 is fixedly mounted on the stabilizing plate 61. The third spring 64 is nested on the outer surface of the limiting rod 62. The third spring 64 elastically drives the limiting rod 62 into the limiting hole 65. Calibration plates 66 are fixedly mounted on both sides of the mounting frame 51 near the air duct 3. The calibration plates 66 improve the accuracy of the mounting frame 51 installation and enhance the calibration capability of the device. When using the device, first pull the limiting rod 62 to cause the baffle 63 to compress the third spring 64. Then, move the mounting frame 51 to insert the calibration plate 66 into the air duct 3. Then, release the limiting rod 62 so that it is inserted into the limiting hole 65 under the elastic force of the third spring 64. This facilitates installation and disassembly, improves the efficiency of device disassembly and replacement, and extends the service life of the device.

[0036] Please see Figure 1 - Figure 7 As shown, an automotive radiator includes a vehicle body heat-preventing air recirculation mechanism, which is installed on the radiator. It also includes a radiator body 1, on which a guide frame 12 is provided. The guide frame 12 facilitates the absorption of heat from inside the vehicle onto the radiator body 1. A sliding groove 14 is provided within the guide frame 12, and a filter plate 13 is slidably installed within the sliding groove 14. The filter plate 13 is easy to disassemble, clean, and replace. The filter plate 13 not only filters impurities in the hot air but also minimizes damage to the radiator body 1 from impurities, thus protecting the radiator body 1 and extending its service life. A locking assembly 7 is provided on the radiator body 1.

[0037] Please see Figure 4 and Figure 6 As shown, a fixing plate 15 is rotatably installed on the side of the guide frame 12 near the filter plate 13. The fixing plate 15 serves to limit and fix the filter plate 13. A placement plate 17 is fixedly installed at the bottom of the radiator body 1. The placement plate 17 is used to place and stabilize the guide frame 12.

[0038] Please see Figure 6 and Figure 7 As shown, the engaging assembly 7 includes an engaging plate 73. Two support plates 71 are fixedly installed on the radiator body 1. The support plates 71 are used to support the installation of the bidirectional screw 72. The bidirectional screw 72 is rotatably installed between the two support plates 71. The engaging plate 73 is threaded through and installed on the bidirectional screw 72. The bidirectional screw 72 plays the role of driving the engaging plate 73 into the engaging groove 75. Two mounting plates 74 are fixedly installed on the side of the guide frame 12 near the radiator body 1. The mounting plates 74 play the role of clamping and limiting the guide frame 12. Engaging grooves 75 are opened on the two mounting plates 74. A knob 76 is fixedly installed on one end of the bidirectional screw 72 that is threaded through one of the support plates 71.

[0039] Please see Figure 6 and Figure 7As shown, the locking plate 73 is inserted into the locking groove 75 to facilitate locking and fixing the guide frame 12. The bottom surface of the locking plate 73 slides against one side of the radiator body 1. There are two locking plates 73, which are threaded onto the two ends of the bidirectional screw 72 respectively. When using the device, first move the guide frame 12 so that the mounting plates 74 on both sides clamp the radiator body 1. Then push the guide frame 12 to move onto the placement plate 17. Then turn the knob 76 to make the knob 76 drive the bidirectional screw 72 to rotate. At the same time, the bidirectional screw 72 drives the locking plate 73 to slide on the radiator body 1 and insert the locking plate 73 into the locking groove 75 in the mounting plate 74 to facilitate locking and fixing the position of the guide frame 12. This facilitates installation and disassembly, improves the safety and stability of the device, facilitates operation and use, and improves the heat dissipation capacity of the device.

[0040] The working principle of this invention is as follows: When using the device, first, move the guide frame 12 so that the mounting plates 74 on both sides clamp the radiator body 1. Then, push the guide frame 12 to move onto the placement plate 17. Then, turn the knob 76 so that the knob 76 drives the bidirectional screw 72 to rotate. At the same time, the bidirectional screw 72 drives the locking plate 73 to slide on the radiator body 1, and the locking plate 73 is inserted into the locking groove 75 in the mounting plate 74 to facilitate locking and fixing the position of the guide frame 12. Then, pull the limiting rod 62 so that the limiting rod 62 drives the baffle 63 to squeeze the third spring 64, so that the third spring 64 is in a compressed state. Then, move the mounting frame 51 so that the calibration plate 66 is inserted into the air duct 3. Then, release the limiting rod 62 so that the limiting rod 62 is inserted under the elastic force of the third spring 64. Enter the limiting hole 65, then start the exhaust fan 8, so that the exhaust fan 8 drives the hot air to blow onto the air guide plate 9 and blow open the sealing strip 11. At the same time, the air guide plate 9 is squeezed by the wind force, so that the first spring 10 is in a compressed state. Then the hot air is discharged into the air guide pipe 3, so that the hot air is discharged through the dustproof nets 4 at both ends of the air guide pipe 3, which facilitates the discharge of hot air. When the vehicle is moving, the bumps cause the sliding frame 52 to slide within the mounting frame 51. At the same time, the sliding frame 52 squeezes the telescopic rod 53 and the second spring 54, so that the telescopic rod 53 and the second spring 54 are in a compressed state. The second spring 54 is frequently compressed and reset, which makes it easy for the sliding frame 52 to drive the cleaning plate 55 to scrape back and forth on the dustproof net 4, which is convenient for cleaning the dust adsorbed on the dustproof net 4 and is easy to operate.
