Problems solved by technology

In the prior art, most oil coolers realize oil cooling through the integration of oil channels and water channels. After a period of use, impurities in the oil and coolant can easily cause channel blockage, reduce the cooling performance of the oil, and even cause leakage. In addition, this method is very prone to engine oil-water mixing, which will cause major accidents such as crankshaft locking and supercharger damage; in addition, the structure of this method is complicated, and it is necessary to separately develop water inlet pipes, return water pipes and other pipes Road, large layout space, many sealing surfaces, high cost

Embodiment

[0030] A kind of engine oil cooler that this embodiment relates to, such as figure 1 , figure 2 , image 3 As shown, it includes a body 9, which is a quadrilateral structure, and consists of a main body 1 with an open front end and a hollow cavity, and a cover plate 8 fixed at the opening of the main body 1 . The bottom end of the main body 1 is fixedly connected to the outer wall of the engine water jacket, and the front end face is the mounting end face 3 . The lower left corner of the installation end face 3 is provided with an oil inlet 4, and the upper right corner is provided with an oil outlet 5, which makes the oil inlet 4 and the oil outlet 5 be arranged on both ends of the maximum dimension line of the hollow cavity. If the shape of the end face of the hollow cavity is circular, the oil inlet hole 4 and the oil outlet hole 5 are arranged at both ends of the diameter of the circle. Mounting holes 7 are respectively provided at the upper left corner and the lower r...

Abstract

The invention discloses an engine oil cooler which is fixedly arranged on the outer wall of an engine water jacket. The engine oil cooler comprises a body with a hollow cavity, wherein the body is provided with an oil inlet and an oil outlet, the hollow cavity is internally provided with multiple heat transfer web plates which are fixedly connected to the body, and the heat transfer web plates divide the hollow cavity into multiple channels which communicate the oil inlet hole with the oil outlet hole. The engine oil cooler provided by the invention utilizes the heat transfer web plate to carry out cooling on oil, and has the characteristics of being simple and compact in structure, low in cost and suitable for volume production; and the engine oil cooler is suitable for being installed on various engines.

Description

technical field [0001] The invention relates to an automobile engine cooling device, in particular to an engine oil cooler. Background technique [0002] When the car engine is running at high load, the concentration of the engine oil will become thinner with the increase of temperature, which will reduce the lubricating ability of the engine oil. The function of the oil cooler is to cool the oil so that the oil temperature is within the normal working range and ensure that the oil has a certain viscosity. In the prior art, most oil coolers realize oil cooling through the integration of oil channels and water channels. After a period of use, impurities in the oil and coolant can easily cause channel blockage, reduce the cooling performance of the oil, and even cause leakage. oil failure phenomenon; in addition, this method is very prone to engine oil-water mixing, which will cause major accidents such as crankshaft locking and supercharger damage; in addition, this method h...
