Description

Technical Field

[0001] This utility model relates to the technical field of automotive transmission cooling equipment, and in particular to a cooling device for automotive transmissions. Background Technology

[0002] The automotive transmission is a core component of the vehicle's drivetrain. Its main function is to adjust the engine's output torque and speed by changing the gear ratio, thereby adapting to different driving conditions, such as starting, acceleration, climbing hills, and high-speed cruising. The performance of the transmission directly affects the vehicle's power transmission efficiency, fuel economy, and driving comfort.

[0003] Transmissions generate a significant amount of heat during operation, primarily from gear friction and fluid churning. If this heat cannot be dissipated promptly, it can lead to excessively high transmission oil temperatures, affecting oil performance, reducing gear lubrication, and even causing transmission malfunctions. Therefore, heat dissipation is a crucial aspect of transmission design.

[0004] Car transmissions generate a significant amount of heat during operation. If this heat cannot be dissipated in time, it can lead to excessively high transmission oil temperatures, affecting the transmission's lubrication and mechanical performance, and even causing malfunctions. However, current transmissions typically dissipate heat through heat exchange between the transmission housing and the air, which is inefficient and insufficient for high-load operation.

[0029] like Figures 1 to 7 As shown in the figure, this embodiment provides a heat dissipation device for an automotive transmission. This heat dissipation device includes a housing body 1.

The top of the liquid distribution tank 501 is provided with a first liquid pump 502, and the liquid distribution tank 501 is connected to the first liquid pump 502 through a second liquid pump 5052. The first liquid pump 502 is provided with a second liquid delivery pipe 5021 connected to the end of the serpentine cooling pipe 402 away from the first liquid delivery pipe 4021. The main body 1 is the main structure of the gearbox, and the gearbox is installed inside to realize the power transmission and speed change function. The assembly guide rail 2 is used to slide and connect with the protective shell 3. The metal radiator body 401 is used to transfer the heat generated by the gearbox to the coolant through the first liquid delivery pipe 4021 and the serpentine cooling pipe 402. A semiconductor cooling chip 404 is embedded in it to further reduce the temperature of the coolant in the serpentine cooling pipe 402, thereby improving the heat dissipation effect of the main body 1.

[0030] Symmetrically distributed limiting sliders 301 are fixedly installed on the outer side of the protective housing 3. Symmetrically distributed openings 302 are also provided on the side of the protective housing 3 near the main body 1. Ventilation slots 303 are arranged on the side of the protective housing 3 away from the main body 1 and below the fan frame 403. Assembly holes 304 for assembly are provided at the four corners of the protective housing 3. The limiting sliders 301 are used to slide and limit the movement within the assembly guide rail 2, which facilitates the installation of the protective housing 3. The openings 302 allow airflow at the bottom of the main body 1, promoting the heat dissipation of the main body 1 itself. The ventilation slots 303 provide airflow for the semiconductor cooling chip 404, enhancing the heat dissipation effect. The protective housing 3 is fixed to the car chassis or other installation position through the assembly holes 304 to ensure stable operation of the device.

[0031] The protective housing 3 has symmetrically distributed pre-installed plates 305 fixedly installed, and the fan frame 403 is slidably connected between the pre-installed plates 305. Both ends of the pre-installed plates 305 are provided with arranged adjustment grooves 3051. The pre-installed plates 305 are also provided with bolt locking parts 306. The second liquid infusion pipe 5021 passes through one end of the bolt locking part 306 and is connected to the serpentine cooling pipe 402.

[0032] The separatory tank 501 is also equipped with a return pipe 503, and one end of the return pipe 503 extends outside the separatory tank 501 and is connected to the serpentine cooling pipe 402. The return pipe 503 is equipped with a filter canister for filtration, and the filter canister is also equipped with a second injection pipe 504 connected to the separatory tank 501. The return pipe 503 is used to return the cooled coolant to the separatory tank 501. The filter canister on the return pipe 503 is used to filter impurities in the coolant, and the treated coolant is sent back to the separatory tank 501 for recycling through the second injection pipe 504.

[0033] The reinforcing component 5 also includes a liquid storage tank 505 fixedly installed in the protective housing 3. The liquid storage tank 505 is equipped with a liquid filling pipe 5051 for adding coolant, with one end of the liquid filling pipe 5051 extending outside the protective housing 3. The liquid storage tank 505 is connected to the distribution tank 501 via a second liquid pump 5052. The liquid storage tank 505 is used to store spare coolant. The liquid filling pipe 5051 on the liquid storage tank 505 is used to replenish coolant, and the coolant always flows in a unidirectional direction.

[0034] The inner side of the assembly guide rail 2 is provided with a slide groove 201 for limiting the movement of the limiting slider 301. Both ends of the slide groove 201 and the assembly guide rail 2 are also provided with a slot 202 corresponding to the limiting slider 301. The slide groove 201 and the slot 202 are used to limit and fix the limiting slider 301 in the protective housing 3, respectively.

[0035] The four corners of the box body 1 are provided with symmetrically distributed pre-installed holes 101 for assembly, which are used to fix the box body 1 to the car chassis or other installation positions.

[0036] When assembling the protective housing 3 with the main body 1, the first step is to align the limiting slider 301 on the outside of the protective housing 3 with the groove 201 on the assembly guide rail 2 at the bottom of the main body 1. Then, along the direction of the groove 201, the protective housing 3 is slidably installed under the main body 1 until the protective housing 3 completely covers the bottom of the main body 1, and the limiting slider 301 slides into place in the groove 201 and falls into the corresponding slot 202. This simplifies the assembly process and reduces the assembly difficulty. The bottom of the main body 1 has an opening 302 to allow air to flow and ensures that the heat dissipation component 4 in the protective housing 3 is located under the main body 1 and operates normally. Finally, the main body 1 and the protective housing 3 are fixed to the frame with bolts through the pre-installation holes 101 at the four corners of the main body 1 and the assembly holes 304 at the four corners of the protective housing 3, completing the entire assembly process and ensuring the stability of the device during operation. The metal radiator body 401 in the heat dissipation assembly 4 absorbs the heat generated by the gearbox through the serpentine cooling pipe 402 and transfers the heat to the coolant. The coolant circulates in the serpentine cooling pipe 402. At the same time, the semiconductor cooling chip 404 in the fan frame 403 further reduces the temperature of the coolant. The fan frame 403 is slidably connected in the protective housing 3 by the pre-mounted plate 305 and the position of the fan frame 403 is adjusted by the adjustment groove 3051. Finally, it is fixed by the bolt locking part 306, which facilitates the assembly of the device and enhances the heat dissipation effect. The liquid distribution tank 501 in the reinforcement assembly 5 delivers coolant to the serpentine cooling pipe 402 through the first liquid pump 502 and the second liquid delivery pipe 5021 to ensure a continuous supply of coolant. The return pipe 503 returns the cooled coolant to the liquid distribution tank 501 and filters impurities through the filter can to keep the coolant clean. The liquid storage tank 505 replenishes the liquid distribution tank 501 with coolant through the second liquid pump 5052 to ensure an adequate supply of coolant.
