[0002] Oil cooler is important assembly part in engine cooling lubrication system, it is a kind of device that accelerates lubricating oil heat dissipation to keep lower temperature.Oil cooler must be installed on high-performance, high-power reinforced engine due to high heat load.Oil cooler is arranged in lubricating oil circuit, and its working principle is same as radiator, the core of air-cooled oil cooler is composed of many cooling pipes and cooling plates, and the core of hot oil cooler is cooled by vehicle head wind when vehicle is running.Water-cooled oil cooler places oil cooler in cooling water circuit, and uses the temperature of cooling water to control the temperature of lubricating oil.When lubricating oil temperature is high, cooling water is used to reduce temperature, and when engine starts, lubricating oil temperature is rapidly increased by absorbing heat from cooling water.Oil cooler is composed of shell made of aluminum alloy, front cover, rear cover and copper core pipe.In order to strengthen cooling, fin is sleeved on pipe.Cooling water flows outside pipe, lubricating oil flows in pipe, and heat exchange is carried out.There is also the structure that oil flows outside pipe, and water flows in pipe.

[0003] In prior art oil cooler, after cooling water passes through oil cooler core, due to large backwater cavity, uneven flow channel shape and uneven fluid flow rate, oil cooling is poor, and oil temperature is high.

[0004] In addition, engine oil cooler lacks modularization design, and generalization degree is poor. INVENTION CONTENTS

[0007] The utility model uses inlet and return water partition, prevents water flow to collide when cooling water enters oil cooler core and flows out through cooler core, after cooling water flows out through oil cooler core, due to the large size of water return cavity, uneven flow channel shape and uneven fluid flow rate, set water cavity partition to prevent water flow to collide, which leads to poor oil cooling, high oil temperature and other phenomena, which is beneficial to the stable operation of engine body. At the same time, the highly integrated design idea has the characteristics of full function and small size.

[0008] Specifically, the oil return port is arranged above the right of the upper cavity of the cooling water return cavity, and the oil inlet is arranged below the left of the lower cavity of the cooling water return cavity, which is beneficial to the arrangement of the cooling water return cavity position.

[0009] Specifically, it further includes an oil filter mounting seat and an oil filter mounting oil port, both of which are arranged in the lower part of the oil cooler seat. The oil filter is mounted on the oil filter mounting seat, and the oil filter mounting oil port is connected with the oil circuit of the oil filter. The oil filter mounting seat is used for mounting the oil filter, and the oil filter mounting oil port is used for mounting the oil filter and has an oil inlet.

[0012] Specifically, the oil cooler core includes alternating stacked cooling water chips and oil chips. The cooling water chips and oil chips are identical in shape and feature a modular design, allowing for the simultaneous addition or removal of cooling water chips and oil chips based on varying cooling water and oil flow rates. The oil cooler core is used for cooling the oil and contains cooling water channels and cooling oil channels. In this invention, the cooling water chips and oil chips are stacked sequentially, one water chip and one oil chip. Each chip has openings at its water inlet / outlet and oil inlet / outlet holes, allowing for flow. The oil chips have closed structures at the water inlet / outlet holes of the cooling water chips, and vice versa. The cooling water chips and oil chips are identical in shape and feature a modular design, allowing for the simultaneous addition or removal of cooling water chips and oil chips based on varying cooling water and oil flow rates.

[0013] The beneficial effects of this utility model are:

[0014] The inlet and outlet water baffles prevent water flow from colliding as it enters and exits the oil cooler core. The return water chamber baffle prevents uneven flow velocity and poor oil cooling caused by water flow colliding after the coolant exits the oil cooler core, due to the larger chamber and uneven flow path. This promotes stable engine operation. Furthermore, the highly integrated design features comprehensive functionality and a compact size.

[0015] This utility model features a modular oil cooler cooling core design. It can accommodate different engine models on the same engine platform, different engine models on different engine platforms, or engine models with significant differences in displacement and power. The cooling chips can be adapted or adjusted according to the actual cooling and lubrication requirements, thus achieving a modular design for the oil cooler. This standardizes the installation design of oil coolers across different engine platforms, requiring only adjustments to the number of cooling water chips and oil chips in the oil cooler.
