Description

Technical Field

[0001] This invention relates to the field of radiator technology, specifically an automotive water tank radiator. Background Technology

[0002] The automotive radiator, also known as the cooling system radiator, is one of the core components of the automotive thermal management system. It uses circulating coolant to transfer excess heat generated by the engine to the external environment, thereby maintaining the engine's stable operation within a suitable temperature range. The radiator typically consists of an inlet chamber, an outlet chamber, main fins, and a heat dissipation core. The performance of the radiator directly affects the engine's thermal load capacity, fuel economy, and emission control level.

[0003] The core of existing radiators mostly adopts a combination structure of thin-walled metal flat tubes and heat dissipation fins. With the accumulation of use time, rust particles, scale and foreign objects in the cooling medium inside the water tank are prone to deposit in the pipes, resulting in flow channel blockage, local overheating and even corrosion perforation, affecting heat dissipation efficiency and service life. The radiator cannot automatically replenish the loss of cooling medium according to the actual situation, and cannot meet the use requirements. Summary of the Invention

[0004] The purpose of this invention is to provide an automotive radiator to solve the problem of inconvenience in using existing radiators.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An automotive radiator includes a reservoir and further comprises:

[0007] The heat dissipation assembly includes a heat dissipation cylinder disposed above a liquid storage tank, multiple heat dissipation fins disposed outside the heat dissipation cylinder, fixed plates disposed on both sides of the outside of the heat dissipation cylinder, and fixed pipes disposed on the fixed plates. A support frame is disposed on the top of the liquid storage tank, and a fixed plate is disposed on the top of the support frame. The heat dissipation cylinder is rotatably disposed between two fixed plates. A heat dissipation pipe is disposed between two fixed pipes. An inlet pipe is disposed inside the fixed pipe and the inlet pipe penetrates into the heat dissipation pipe.

[0008] A filter assembly for filtering the cooling medium inside a heat sink includes a rotating seat disposed outside the heat sink, a rotating shaft disposed on the rotating seat, and a filter plate disposed on the rotating shaft. The heat sink has a liquid storage tank inside, and the filter plate is disposed inside the liquid storage tank. Air vanes are rotatably disposed on both sides of the rotating seat.

[0009] The fluid replenishment assembly includes an inlet cylinder mounted on top of a storage tank, a rotating plate mounted at the bottom opening of the inlet cylinder, a connecting pipe connecting the inlet cylinder and a fixed pipe, and a piston mounted inside the inlet cylinder. A movable rod is slidably mounted on the top of the inlet cylinder, the bottom end of which passes through the inlet cylinder and connects to the piston. Limiting cylinders are mounted on the adjacent sides of the two support frames, and limiting grooves are formed inside the limiting cylinders. A limiting rod is mounted on the top of the storage tank, and a locking block that cooperates with the limiting groove is mounted outside the limiting rod.

[0010] The transmission mechanism is connected to the heat sink and can drive the movable rod and piston to move up and down according to the rotation of the heat sink. When the coolant is insufficient, the transmission mechanism drives the piston to descend, which can replenish the coolant in the storage tank to the heat sink through the connecting pipe.

[0011] Based on the above technical solutions, the present invention also provides the following optional technical solutions:

[0012] In one alternative embodiment: the transmission mechanism includes a fixed plate, a transmission plate, and a pressure block. The top of the movable rod is provided with a fixed plate, the side wall of the fixed plate is provided with a transmission plate, the side of the transmission plate near the fixed plate is provided with a clamping plate, the side wall of the fixed plate is provided with a transmission groove, and the outside of the heat dissipation cylinder is provided with a pressure block that cooperates with the transmission plate.

[0013] In one alternative: a return spring is sleeved on the outside of the movable rod, one end of the return spring is connected to the piston, a sliding groove is provided on the outside of the transmission plate, and a connecting post is provided on the outside of the fixed plate, the connecting post passing through the sliding groove and slidingly engaging with it.

[0014] In one alternative: a rotating block is provided inside the heat dissipation pipe, and an elastic rod is provided between multiple rotating blocks. Multiple inclined grooves are opened inside the rotating block. The rotating block is sleeved on the outside of the liquid inlet pipe, and a cleaning layer is provided on both the inner and outer sides of the rotating block.

[0015] In one alternative: the heat dissipation pipe has multiple through holes on its exterior, and the heat dissipation cylinder has multiple scrapers inside, with the scrapers in contact with the exterior of the heat dissipation pipe.

[0016] In one alternative: the liquid storage tank is provided with an observation window on the outside, a mounting plate is provided at the bottom of the liquid storage tank, and an injection port is provided at the top of the liquid storage tank.

[0017] In one alternative: the side wall of the liquid storage tank is provided with a locking bolt, one end of which is connected to the support frame.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] The automotive radiator cools the vehicle's coolant through cooling medium in the radiator pipes and heat exchange cylinder. The cooling medium flows through the radiator pipes, carrying heat upwards from the coolant, thus increasing the heat exchange intensity and efficiency of the equipment. The reservoir and inlet cylinder work together to automatically replenish the cooling medium, improving system reliability. When the liquid level drops, the replenishment program is automatically triggered (via pressure blocks, transmission plates, pistons, etc.) to promptly replenish the cooling medium from the reservoir to the circulation pipes, preventing overheating of the coolant due to insufficient cooling medium. This reduces the user's daily maintenance burden and improves driving safety and system reliability. The rotating block chain driven by fluid power can simultaneously scrape away scale and impurities from the inner walls of the inlet pipe and radiator pipe during rotation, preventing pipe blockage and removing scale. The scraped-off impurities enter the liquid flow through the through holes and eventually settle at the bottom of the reservoir. Attached Figure Description

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0032] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0033] like Figure 1-10 As shown, an embodiment of the present invention provides an automotive radiator, including a reservoir 1, and further comprising:

[0034] The heat dissipation assembly includes a heat dissipation cylinder 3 positioned above a liquid storage tank 1, multiple heat dissipation fins 11 positioned outside the heat dissipation cylinder 3, fixed disks 17 positioned on both sides of the outside of the heat dissipation cylinder 3, and fixed pipes 5 positioned on the fixed disks 17. Three sets of heat dissipation fins 11 are arranged around the outer wall of the heat dissipation cylinder 3. A support frame 2 is positioned on the top of the liquid storage tank 1, and a fixed disk 17 is fixedly mounted on the top of the support frame 2. The heat dissipation cylinder 3 is rotatably positioned between two fixed disks 17. A heat dissipation pipe 501 is positioned between two fixed pipes 5, and an inlet pipe 4 is positioned inside the fixed pipe 5, penetrating the interior of the heat dissipation pipe 501. Several U-shaped heat dissipation pipes 501 are connected between the two fixed pipes 5. The unit is equipped with an inlet pipe 4, which penetrates into the heat dissipation pipe 501. The heat dissipation pipe 501 adopts an openable and closable structure, which facilitates the installation and maintenance of the inlet pipe 4. The support frame 2 is elastically installed on the outer wall of the liquid storage tank 1 through an elastic element (such as a telescopic spring), so that the support frame 2 can slide in the vertical direction and obtain an upward support force under the action of the elastic element, which supports the heat dissipation cylinder 3 above. When the cooling medium inside the heat dissipation cylinder 3 is sufficient, the weight of the entire heat dissipation assembly is large, the elastic element is compressed and the support frame 2 is in a low position. When the cooling medium is insufficient, the total weight of the heat dissipation assembly decreases. Under the action of the restoring force of the elastic element, the support frame 2 drives the heat dissipation cylinder 3 to slide upward. This displacement change will trigger the subsequent liquid replenishment assembly to work.

[0035] A filter assembly for filtering the cooling medium inside the heat sink 3 includes a rotating seat 13 disposed outside the heat sink 11, a rotating shaft 131 disposed on the rotating seat 13, and a filter plate 28 disposed on the rotating shaft 131. The heat sink 11 has a liquid storage tank 111 inside, and the filter plate 28 is disposed inside the liquid storage tank 111. Air vanes 12 are rotatably disposed on both sides of the rotating seat 13. The rotating seat 13 is rotatably connected to the heat sink 11 via a torsion spring, so that the air vanes 12 maintain an initial position parallel to the heat sink 11 in their natural state. When the heat sink 11 on the heat sink 3 rotates to the bottom of the heat sink 3, the air vanes 12 on the heat sink 11 at that point are subjected to external wind force. The wind force pushes the air vanes 12 outward and drives the rotating seat 13 to rotate against the torsion spring torque. The rotating seat 13, through the rotating shaft 131, causes the filter plate 28 to tilt within the liquid storage tank 111 (i.e., Figure 9 (as shown in the figure) forms an impurity guiding slope. Under the action of gravity, impurities in the cooling medium slide along the surface of the inclined filter plate 28 to the bottom of the liquid storage tank 111 and are deposited. When the wind vane 12 loses its wind force due to the weakening of the wind or the change of position, under the action of the torsion spring restoring torque, the rotating seat 13 drives the wind vane 12 and the filter plate 28 to return to the initial position. At this time, the filter plate 28 returns to the horizontal state, sealing the liquid storage tank 111 and effectively preventing the overflow of deposited impurities.

[0036] When the car is running, the airflow in front enters the radiator area under the action of the vehicle's movement. The high-speed airflow passes through the gaps between adjacent radiator fins 11, performing convective heat transfer on the cooling medium stored in the reservoir 111, reducing the temperature of the cooling medium. The flowing air carries away the heat accumulated on the surface of the radiator fins 11, enhancing the overall heat dissipation effect. When the radiator fins 11 at the bottom of the radiator cylinder 3 are subjected to the wind force, the fan plate 12 unfolds and generates thrust. When the fan plate 12 moves to a position where it is no longer affected by the wind, it returns to its initial position. At this time, the fan plate 12 is parallel to the radiator fins 11 and cannot drive the radiator cylinder 3 to rotate by the wind force. That is, the fan plate 12 drives the radiator cylinder 3 to rotate continuously in a single direction (rotation direction as shown in the figure). Figure 1 As shown), the heat sink 3 drives the internal cooling medium to move continuously, avoiding temperature stratification and local overheating when the medium is stationary. The heat sink 3 drives multiple heat sinks 11 to rotate synchronously. The cooling medium in the liquid storage tank 111 after heat dissipation is lifted upward under the action of centrifugal force and evenly sprinkled onto the surface of the heat sink 501 below. The lifted cooling medium is in full contact with the heat sink 501, and efficiently absorbs and dissipates heat through heat exchange, improving heat dissipation efficiency. At the same time, the rotating and sprinkled cooling medium can avoid the formation of local dry areas on the surface of the heat sink 501, ensuring heat exchange uniformity and extending the service life of the device.

[0037] The liquid replenishment assembly includes an inlet cylinder 9 located on top of the liquid storage tank 1, a rotating flip plate 26 located at the bottom opening of the inlet cylinder 9, a connecting pipe 6 connecting the inlet cylinder 9 and the fixed pipe 5, and a piston 27 located inside the inlet cylinder 9. A movable rod 20 is slidably provided on the top of the inlet cylinder 9. The bottom end of the movable rod 20 passes into the inside of the inlet cylinder 9 and is connected to the piston 27. The flip plate 26 has an L-shaped structure and can close or open the bottom opening of the inlet cylinder 9 or the connecting pipe 6. A limit cylinder 8 is provided on one side of the two support frames 2 that are close to each other. A limit groove 801 is opened inside the limit cylinder 8. A limit rod 19 is provided on the top of the liquid storage tank 1. A locking block 191 that cooperates with the limit groove 801 is provided on the outside of the limit rod 19.

[0038] The transmission mechanism is connected to the heat sink 3 and can drive the movable rod 20 and piston 27 to move up and down according to the rotation of the heat sink 3. When the coolant is insufficient, the transmission mechanism drives the piston 27 to descend, which can replenish the coolant in the storage tank 1 to the heat sink 3 through the connecting pipe 6.

[0039] like Figure 1-8As shown, in a preferred embodiment of the present invention, the transmission mechanism includes a fixed plate 22, a transmission plate 21, and a pressure block 10. The top of the movable rod 20 is provided with a fixed plate 22, and the side wall of the fixed plate 22 is provided with a transmission plate 21. A clamping plate 212 is provided on the side of the transmission plate 21 near the fixed plate 22. A transmission groove 221 is formed on the side wall of the fixed plate 22. A pressure block 10 that cooperates with the transmission plate 21 is provided outside the heat dissipation cylinder 3. The clamping block 191 outside the limiting rod 19 is made of an elastic metal sheet and can be engaged inside the limiting groove 801 of the limiting cylinder 8. When the cooling medium inside the heat dissipation cylinder 3 is sufficient, the overall weight of the heat dissipation assembly is large, compressing the elastic element to place the support frame 2 in a low position. At this time, the clamping block 191 engages at the bottom of the limiting groove 801, limiting and fixing the support frame 2. The transmission plate 21 and the fixed plate 22 are in a separated state (e.g., Figure 7 As shown), when the pressure block 10 rotates with the heat dissipation cylinder 3 and periodically presses the transmission plate 21 downward, the transmission plate 21 can rotate downward to avoid it, and the fixed plate 22 and the movable rod 20 remain stationary.

[0040] When the cooling medium inside the heat sink 3 decreases, the weight of the heat sink assembly decreases. After the weight decreases to a certain extent, under the supporting force of the elastic element, the support frame 2 drives the limiting cylinder 8 to move upward. The locking block 191 is pressed out of the current limiting groove 801 and locks into the adjacent upper limiting groove 801, thus re-limiting and fixing the limiting cylinder 8 and the support frame 2. At this time, the limiting cylinder 8 moves to... Figure 6 At the indicated position, its sidewall pushes the transmission plate 21 to move horizontally, causing the clamping plate 212 to embed into the transmission groove 221 of the fixed plate 22. The transmission plate 21 and the fixed plate 22 form a rigid connection. When the pressure block 10 rotates to the lower position with the heat dissipation cylinder 3, it presses down on the locked transmission plate 21. The fixed plate 22 drives the movable rod 20 and piston 27 to move down. The piston 27 descends and generates pressure in the liquid inlet cylinder 9, causing the cooling medium in the liquid storage tank 1 to move downward and drive the flip plate 26 to rotate. The flip plate 26 closes the bottom of the liquid inlet cylinder 9 downward, and the connecting pipe 6 opens. The cooling medium is replenished to the heat dissipation pipe 501 through the connecting pipe 6, completing the automatic liquid replenishment process and ensuring the stability and reliability of the heat dissipation system.

[0041] like Figure 1-7 As shown, in a preferred embodiment of the present invention, a return spring 29 is sleeved on the outside of the movable rod 20. One end of the return spring 29 is connected to the piston 27, providing the return force of the piston 27. A sliding groove 211 is provided on the outside of the transmission plate 21. A connecting post 25 is provided on the outside of the fixed plate 22. The connecting post 25 passes through the sliding groove 211 and slides with it. Through the cooperation between the sliding groove 211 and the connecting post 25, the switching of the working state of the transmission plate 21 is realized.

[0042] like Figure 1-8As shown in a preferred embodiment of the present invention, a rotating block 23 is provided inside the heat dissipation pipe 501, and an elastic rod 24 is provided between the multiple rotating blocks 23. Multiple inclined grooves 231 are formed inside the rotating block 23. The rotating block 23 is sleeved on the outside of the liquid inlet pipe 4. A cleaning layer is provided on both the inner and outer sides of the rotating block 23. When the cooling medium flows in the heat dissipation pipe 501, the fluid passes through the inclined grooves 231, generating thrust and driving the rotating block 23 to rotate around the axis of the liquid inlet pipe 4. The multiple rotating blocks 23 are linked by the elastic rods 24 to form continuous rotation. During rotation, the cleaning layer on the inner side of the rotating block 23 maintains contact and friction with the outer wall of the liquid inlet pipe 4, effectively cleaning... In addition to removing scale, impurities, and deposits adhering to the outer surface of the inlet pipe 4, the outer cleaning layer of the rotating block 23 contacts the inner wall of the heat dissipation pipe 501, removing the dirt accumulated on the inner wall of the pipe. The design of the elastic rod 24 gives the rotating blocks 23 a certain degree of self-adaptability, ensuring full contact between the cleaning layer and the pipe wall, while also adapting to the passage of the pipe bends. By utilizing the flow energy of the cooling medium, bidirectional synchronous cleaning of the inlet pipe 4 and the heat dissipation pipe 501 is achieved, effectively preventing scale and blockage on the pipe wall and maintaining the efficient operation of the heat dissipation system. The cleaning layer is made of wear-resistant rubber or composite material, and the surface is provided with flexible bristles or raised structures to ensure the cleaning effect and avoid damage to the pipe wall.

[0043] like Figure 1-6 As shown, in a preferred embodiment of the present invention, the heat dissipation pipe 501 has multiple through holes 502 on its outside, and the heat dissipation cylinder 3 is provided with multiple scrapers 18 inside. The scrapers 18 are in contact with the outside of the heat dissipation pipe 501. When the heat dissipation cylinder 3 rotates, the scrapers 18 continuously scrape off the scale, impurities and deposits attached to the outer wall of the heat dissipation pipe 501. The scraped-off impurities fall into the liquid storage tank 111 for sedimentation treatment.

[0044] like Figure 1 As shown, in a preferred embodiment of the present invention, the liquid storage tank 1 is provided with an observation window 15 on the outside for visually displaying the capacity and cleanliness of the cooling medium. The liquid storage tank 1 is provided with a mounting plate 16 at the bottom and a liquid injection port 14 at the top. The mounting plate 16 has multiple mounting holes to facilitate the overall installation and fixation of the radiator. The liquid injection port 14 is used for initial filling or replenishment of the cooling medium.

[0045] like Figure 1 As shown, in a preferred embodiment of the present invention, the side wall of the liquid storage tank 1 is provided with a locking bolt 7. One end of the locking bolt 7 is connected to the support frame 2. When the automatic liquid replenishment function is not required, the support height of the support frame 2 can be fixed by rotating the locking bolt 7.

[0046] The above embodiments of the present invention provide an automotive radiator. The sealing cap of the filling port 14 at the top of the reservoir 1 is opened, and sufficient cooling medium is added to the reservoir 1 through the filling port 14. Real-time observation is performed through the observation window 15 and scale lines. The coolant lines of the automotive alternator are connected to both ends of the inlet pipe 4. After the car starts and moves, natural wind flows into the radiator assembly. The airflow passes through the gaps between the radiator fins 11, forcibly cooling the cooling medium in the reservoir 111 and carrying away heat. Simultaneously, the airflow blows the fan plate 1 at the bottom of the radiator cylinder 3. 2. This causes the heat sink 3 to rotate continuously in a single direction, generating thrust. Inside the heat sink 3, as the heat sink 11 rotates upward, the cooling medium in the liquid storage tank 111 is evenly sprayed downward onto the heat dissipation pipe 501 below, efficiently absorbing heat through evaporative heat exchange. The fan plate 12 on the heat sink 11, which has rotated to the bottom, is pushed by the wind force and drives the filter plate 28 to tilt through the rotating seat 13, causing impurities in the medium to slide into the bottom of the liquid storage tank 111 and settle. When the fan plate 12 rotates out of the wind force zone, it resets under the action of the torsion spring, and the filter plate 28 closes to prevent impurities from overflowing.

[0047] When the coolant level decreases due to evaporation or leakage, the total weight of the heat dissipation components (heat sink 3, support frame 2, etc.) decreases. The supporting force of the bottom elastic element causes the support frame 2 to move the limiting cylinder 8 upward by one step. At this time, the locking block 191 on the limiting rod 19 disengages from the original limiting groove 801 and locks into the adjacent upper limiting groove 801, completing the displacement positioning. The upward-moving side wall of the limiting cylinder 8 pushes the transmission plate 21 to rotate horizontally, causing the locking plate 212 on it to embed into the transmission groove 221 of the fixed plate 22, locking the two together as one. When the pressure block 10 of the rotating heat sink 3 rotates to the lowest point, it presses down on the locked transmission plate 21. The downward pressure is transmitted to the movable rod 20 through the fixed plate 22, which overcomes the elastic force of the return spring 29 and pushes the piston 27 to move downward. The piston 27 moves downward in the liquid inlet cylinder 9, and the cooling medium in the liquid inlet cylinder 9 is pressed into the fixed pipe 5 through the connecting pipe 6, and finally replenishes the entire heat dissipation circulation pipeline. After the liquid replenishment is completed, the system weight is restored, and the support frame 2 presses down on the elastic element to reset under the action of gravity. The transmission mechanism disengages and waits for the next trigger.

[0048] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
