Description:COOLING SYSTEM FOR A VEHICLE

FIELD OF THE DISCLOSURE
[0001] This invention generally relates to a field of vehicle cooling systems and in particular, to a cooling system for a vehicle that enhances temperature regulation around major components of the vehicle.

BACKGROUND
[0002] The subject matter discussed in the background section should not be assumed to be prior art merely as a result of its mention in the background section. Similarly, a problem mentioned in the background section or associated with the subject matter of the background section should not be assumed to have been previously recognized in the prior art. The subject matter in the background section merely represents different approaches, which in and of themselves may also correspond to implementations of the claimed technology.
[0003] In modern vehicles, maintaining optimal engine and transmission temperatures is critical for ensuring efficiency, durability, and reliability during operation. Excessive heat generated during prolonged or high-intensity use can significantly impact the performance and lifespan of critical vehicle components, such as the engine and transmission assembly. Effective cooling systems play a pivotal role in dissipating this heat, thereby preventing thermal stress and maintaining operational stability.
[0004] Transmission oil, in particular, needs to be cooled to prevent overheating, which can degrade the fluid, reduce its lubricating properties, and cause significant damage to transmission components. Proper cooling of the transmission oil helps maintain its integrity, ensures efficient operation, and extends the lifespan of the transmission assembly. This is especially crucial under heavy loads or high-stress conditions.
[0005] Traditionally, a heat exchanger is used to cool the transmission oil by transferring heat to the engine coolant. However, in certain scenarios, the temperature of the engine coolant exiting the main radiator is higher than the required specification for effective cooling at the heat exchanger. To address this, additional cooling is required to lower the coolant temperature to meet the specifications for the heat exchanger. This necessitates the implementation of a separate cooling system to ensure the coolant meets the required temperature levels for efficient transmission oil cooling.
[0006] Competitive vehicles with larger engine sizes often exhibit better heat dissipation and airflow characteristics due to their higher engine volumes and larger cabin designs. These vehicles typically have sufficient space to accommodate auxiliary radiators in front of the main radiator, enabling efficient cooling system operation.
[0007] However, in vehicles equipped with an engine, which provides the same mechanical output as larger engines but features a smaller size, several challenges arise. The smaller engine size, coupled with a compact cabin design, smaller fan size, and lower airflow, results in less effective cooling compared to competitive vehicles. Moreover, space constraints in such designs make it infeasible to assemble an auxiliary radiator in front of the main radiator.
[0008] According to the patent application “US10132403B1” titled “Engine and transmission temperature control system” discloses a transmission oil cooler transfers heat between Automatic Transmission Fluid (ATF) and engine coolant. During initial vehicle warm-up, heat is transferred from the engine coolant to the ATF, assisting the transmission warm-up. A priority valve may limit the flow of coolant to the transmission oil cooler until the coolant temperature is sufficient to ensure adequate cabin heating performance. After both the engine and transmission have reached normal operating temperatures, heat is transferred from the ATF to the engine coolant. An auxiliary radiator pre-cools the engine coolant before it enters transmission oil cooler. This increases the cooling of the ATF and avoids coolant temperature increase during aggressive manoeuvres. When the ATF temperature is below a threshold, a coolant control valve diverts coolant around the auxiliary radiator.
[0009] Another patent application, " US6536381B2," titled " Vehicle lubricant temperature control," the invention relates to an oil cooling system in the environment of an over the road vehicle having a transmission and an internal combustion engine. A primary liquid to liquid heat exchanger is connected to the engine cooling system and connected to a selected on of, or both, an engine lubricant system and the transmission for cooling circulation of oil. An auxiliary heat exchanger is connected in parallel with the primary heat exchanger for selective additional cooling circulation of the oil.
[0010] In any of the discussed prior arts, the system(s) does not address the challenges associated with compact vehicle designs, such as those featuring smaller engine sizes that produce the same mechanical output as larger engines, smaller cabin sizes, smaller fan sizes, reduced airflow, and space constraints. These limitations make it impractical to assemble an auxiliary radiator in front of the main radiator. Furthermore, the system(s) do not propose innovative solutions, such as the strategic placement of an auxiliary radiator on the right, middle, and outside of the chassis, to ensure efficient cooling performance while overcoming spatial limitations.
OBJECTIVES OF THE INVENTION
[0011] An objective of the present invention is to provide a cooling system for a vehicle that ensures efficient and reliable temperature management for critical components, including the engine and transmission assembly.
[0012] Furthermore, the objective of the present invention is to enable effective cooling of the transmission oil by addressing the need for additional cooling to lower the temperature of engine coolant.
[0013] Furthermore, the objective of the present invention is to address space constraints in vehicles with compact designs, such as those equipped with smaller engine sizes and cabins.
[0014] Furthermore, the objective of the present invention is to enhance overall thermal regulation of the vehicle's cooling system, ensuring efficient operation under heavy load and high-stress conditions.
[0015] Furthermore, the objective of the present invention is to improve the thermal efficiency of the cooling system in compact vehicles while maintaining compatibility with the spatial limitations of the chassis.
[0016] Furthermore, the objective of the present invention is to ensure consistent cooling performance by accommodating innovative radiator placements, contributing to improved vehicle reliability and durability.
