A leak-proof engine radiator Technical Field
[0001] This utility model relates to the field of automotive engineering technology, and in particular to an engine radiator that prevents water leakage. Background Technology
[0002] The engine radiator is the core component of a car engine cooling system. It mainly absorbs the heat generated by the engine during operation through the circulation of coolant, and dissipates the heat to the external environment by using a fan to drive airflow through the cooling structure, so as to maintain the engine operating within a suitable temperature range. It typically includes key components such as the water tank body, cooling unit, fan, and inlet and outlet coolant pipes. The structural design must take into account the heat dissipation efficiency, installation compatibility and operational stability, and plays an important role in the safe and reliable operation of the car's power system.
[0003] Existing engine radiators often suffer from minor leaks that are difficult to detect promptly using conventional methods. Leaks are frequently only noticed when significant coolant loss affects engine operation, potentially leading to serious problems like overheating. These radiators typically employ a single or symmetrical fan layout, concentrating airflow in a localized area and causing uneven cooling. Furthermore, they rely on multiple motors or transmission structures, increasing the device's size, weight, and probability of failure. The airflow after cooling also exhibits poor guidance, causing some heat to accumulate in the surrounding area. Therefore, we propose a leak-proof engine radiator to address these issues. Summary of the Invention
[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.
[0005] Therefore, the purpose of this utility model is to provide an engine radiator that avoids water leakage. It can solve the problem that existing engine radiators often have minor leaks that are difficult to detect in time through conventional structures. They are often only noticed when a large amount of coolant is lost and affects the normal operation of the engine, which can easily lead to serious problems such as engine overheating. They often use a single fan or a symmetrical fan layout, which concentrates the cooling airflow in a local area, easily leading to uneven heat dissipation. In addition, they rely on multiple motors or multiple sets of transmission structures for drive, which increases the size, weight and probability of failure of the device. Furthermore, the airflow after cooling has poor guidance, and some heat is easy to accumulate in the surrounding area.
[0006] To solve the above-mentioned technical problems, this utility model provides an engine radiator that avoids water leakage, adopting the following technical solution: It includes a water tank body, the water tank body being an open V-shape with an included angle of 120 degrees. A first cooling fan and a second cooling fan are respectively fastened to the left and right sides of the water tank body. Baffles are installed around the first and second cooling fans. A space clearance groove is provided inside the water tank body, and a radiator is fastened to the space clearance groove. A ventilation baffle is provided directly below the first and second cooling fans on the V-shaped water tank body.
[0007] Optionally, a drive shaft is axially connected to the front of the water tank body, and drive shafts are axially installed in front of both the first and second cooling fans. The drive shaft is connected to the drive shafts of the first and second cooling fans respectively via a first drive belt and a second drive belt to achieve power transmission.
[0008] Optionally, the heat dissipation tank and the space clearance groove are fully interference-fitted, the heat dissipation tank is a whole and is composed of several heat dissipation plates, and the heat dissipation plates are set at an angle downward.
[0009] Optionally, a coolant inlet module is fixedly installed directly above the first cooling fan, a coolant inlet pipe is fixedly installed directly above the coolant inlet module, and a coolant outlet pipe is fixedly installed directly below the water tank body. The radiator is connected to the coolant inlet module and the coolant outlet pipe respectively, forming a loop for coolant circulation.
[0010] Optionally, a guide plate is installed at the rear of the water tank body. The guide plate is fastened to the water tank body by bolts. The guide plate has a number of strip-shaped heat dissipation holes extending along its length direction and the strip-shaped heat dissipation holes are spaced apart along the width direction of the guide plate.
[0011] Optionally, a coolant sensing module is securely installed directly below the guide plate and at the rear of the water tank body. The coolant sensing module and the guide plate are not in conflict and are arranged to avoid each other. The sensing end of the coolant sensing module is located directly below the strip-shaped heat dissipation holes of the guide plate and below the inclined end of the downward-angled heat dissipation plate in the water tank.
[0012] In summary, this utility model has at least one of the following beneficial effects: 1. By designing the water tank body as an open V-shaped structure with a 120-degree angle, and combining it with the first and second cooling fans on the left and right sides, and installing baffles around the fans, while setting ventilation baffles to optimize the airflow path, the main drive shaft drives the two fans through a drive belt, thus achieving the purpose of integrating the heat dissipation structure and simplifying power transmission. This achieves the effect of making the fan airflow evenly dispersed, effectively expanding the heat dissipation area, enhancing heat dissipation efficiency, reducing power loss and device size, lowering the probability of failure, and improving overall operational stability.
[0013] 2. By employing the interference fit between the radiator and the space clearance groove, and the overall structure of the downward-sloping radiator plate, along with the placement of the guide plate and coolant sensing module, where the sensing end of the module is located below the strip-shaped heat dissipation holes on the guide plate and the inclined end of the radiator plate, a sealed heat dissipation and precise leak detection system is achieved. This prevents coolant leakage, guides the coolant to flow rapidly to improve heat dissipation, and, in the event of a leak, utilizes the slope of the radiator plate and the guide plate to guide the leaking liquid quickly to the sensing end, allowing for timely detection of the leak and preventing engine damage due to coolant leakage.

[0020] The present invention will be further described in detail below with reference to Figures 1-4.
[0021] Example 1, referring to Figures 1-4, addresses the issue of minor leaks in existing engine radiators, which are difficult to detect promptly using conventional structures. Leaks often only become apparent when significant coolant loss affects engine operation, leading to serious problems like overheating. These radiators typically employ a single fan or a symmetrical fan layout, concentrating airflow locally and causing uneven cooling. Furthermore, they rely on multiple motors or transmission structures, increasing device size, weight, and the probability of failure. The airflow after cooling also suffers from poor guidance, with some heat easily accumulating in the surrounding area. This invention discloses a leak-proof engine radiator.
[0022] The system includes a water tank body 1, which is an open V-shape with an included angle of 120 degrees. A first cooling fan 2 and a second cooling fan 3 are securely mounted on the left and right sides of the water tank body 1, respectively. Both the first cooling fan 2 and the second cooling fan 3 are surrounded by baffles 4. An internal clearance groove 5 is provided inside the water tank body 1, within which a cooling water tank 6 is securely mounted. A ventilation baffle 7 is located directly below the first cooling fan 2 and the second cooling fan 3 on the V-shaped water tank body 1. This allows the water tank body to... The design features an open V-shaped structure with a 120-degree angle, which, together with the first cooling fan 2 and the second cooling fan 3 securely mounted on the left and right sides, achieves airflow dispersion and effectively improves the heat dissipation area and efficiency. The baffle 4 installed around the fans avoids airflow diffusion loss and enhances airflow guidance. The secure installation of the internal space clearance groove 5 of the water tank body 1 and the cooling water tank 6 ensures structural stability and sealing. The ventilation baffle 7 located directly below the two fans on the V-shaped water tank body 1 further optimizes the airflow path and accelerates heat dissipation.
[0023] A drive shaft 8 is axially connected to the front of the water tank body 1. A drive shaft 9 is axially installed in front of the first cooling fan 2 and the second cooling fan 3. The drive shaft 8 is connected to the drive shaft 9 of the first cooling fan 2 and the second cooling fan 3 through the first drive belt 10 and the second drive belt 11 respectively to realize power transmission. By axially connecting the drive shaft 8 to the front of the water tank body 1 and installing the drive shaft 9 in front of the first cooling fan 2 and the second cooling fan 3, and establishing a transmission connection using the first drive belt 10 and the second drive belt 11, the purpose of replacing the multi-motor transmission with a single drive shaft is achieved, which simplifies the transmission structure, reduces power loss, and reduces the size and weight of the device.
[0024] The radiator 6 and the space clearance slot 5 are completely interference-fitted. The radiator 6 is an integral unit composed of several heat dissipation plates 61. The heat dissipation plates 61 are set at an angle downwards. By designing the radiator 6 and the space clearance slot 5 to be completely interference-fitted, and adopting an integral radiator 6 structure composed of several downward-angled heat dissipation plates 61, the purpose of tight connection and enhanced sealing is achieved. This effectively prevents coolant leakage, guides the coolant to flow quickly, expands the heat dissipation area, improves heat dissipation efficiency, and enhances the structural strength and stability of the radiator 6.
[0025] A coolant inlet module 12 is securely installed directly above the first cooling fan 2, and a coolant inlet pipe 13 is securely installed directly above the coolant inlet module 12. A coolant outlet pipe 14 is securely installed directly below the water tank body 1. The radiator 6 is connected to the coolant inlet module 12 and the coolant outlet pipe 14 respectively, forming a loop for coolant flow. By securing the coolant inlet module 12 directly above the first cooling fan 2 and connecting it to the coolant inlet pipe 13 in sequence, and installing the coolant outlet pipe 14 directly below the water tank body 1, the radiator 6 is connected to the coolant inlet module 12 and the coolant outlet pipe 14, forming a coolant flow loop, thus achieving the purpose of standardizing the coolant flow path.
[0026] A guide plate 15 is installed at the rear of the water tank body 1. The guide plate 15 is fastened to the water tank body 1 by bolts. Several strip-shaped heat dissipation holes 16 extending along its length are opened on the guide plate 15. The strip-shaped heat dissipation holes 16 are spaced apart along the width direction of the guide plate 15. By fastening the guide plate 15 at the rear of the water tank body 1 with bolts and opening strip-shaped heat dissipation holes 16 extending along the length direction and spaced apart along the width direction on the guide plate 15, the purpose of strengthening the structural connection stability and optimizing the heat dissipation path is achieved. This realizes the orderly flow of heat dissipation airflow, improves heat dissipation efficiency, and at the same time plays a guiding role in preventing possible coolant leakage.
[0027] A coolant sensing module 17 is securely installed directly below the guide plate 15 and at the rear of the radiator body 1. The coolant sensing module 17 and the guide plate 15 are designed to avoid each other. The sensing end of the coolant sensing module 17 is located directly below the strip-shaped heat dissipation holes 16 of the guide plate 15 and below the inclined end of the downward-sloping heat dissipation plate 61 in the radiator 6. By securely installing the coolant sensing module 17 directly below the guide plate 15 and at the rear of the radiator body 1, and by avoiding the guide plate 15, while ensuring that the sensing end is precisely located directly below the strip-shaped heat dissipation holes 16 of the guide plate 15 and below the inclined end of the downward-sloping heat dissipation plate 61 in the radiator 6, the purpose of constructing an efficient leak detection structure is achieved. This allows the leaking coolant to flow quickly to the sensing end when coolant leaks, thanks to the slope of the heat dissipation plate 61 and the guiding effect of the strip-shaped heat dissipation holes 16. This enables timely and sensitive detection of the leak, preventing engine failure caused by coolant leakage.
[0028] The specific working principle is as follows: By designing the water tank body 1 as an open V-shaped structure with a 120-degree angle, and matching it with the first and second cooling fans 3 on the left and right sides, and installing baffles 4 around the fans, and setting ventilation baffles 7 to optimize the airflow path, the transmission main shaft 8 drives the two fans through the transmission belt, thereby achieving the purpose of integrating the heat dissipation structure and simplifying the power transmission. This achieves the effect of making the fan airflow evenly dispersed, effectively expanding the heat dissipation area, enhancing heat dissipation efficiency, reducing power loss and device size, reducing the probability of failure, and improving the overall operational stability. Through the interference fit between the cooling water tank 6 and the space clearance groove 5, the overall structure of the downward-angled heat dissipation plate 61, and the setting of the guide plate 15 and the coolant water sensing module 17, the sensing end of the water sensing module is located below the strip-shaped heat dissipation hole 16 of the guide plate 15 and the inclined end of the heat dissipation plate 61, the purpose of building a sealed heat dissipation and accurate water leakage detection system is achieved. This invention achieves the goals of preventing coolant leakage, guiding coolant flow rapidly to improve heat dissipation, and, in the event of coolant leakage, using the slope of the radiator plate 61 and the guide plate 15 to guide the leaking liquid quickly to the sensing end, thus promptly detecting the leak and preventing engine damage due to coolant leakage. The above are preferred embodiments of this invention and are not intended to limit the scope of protection of this invention. Therefore, all equivalent changes made to the structure, shape, and principle of this invention should be included within the scope of protection of this invention.
