Abstract

The utility model relates to an engine oil cooler, which solves the problems of small heat exchanging areas and poor cooling effect of the existing engine oil cooler. The utility model has the structure that more than two cavity bodies are arranged in one shell body, any one of the adjacent cavity bodies is an oil cavity, the other cavity body is a water cavity, all oil cavities are respectively communicated with an oil intake passage and an oil discharge passage, and all water cavities are respectively communicated with a water intake passage and a water discharge passage. The utility model is improved, the engine oil cooler is formed by superimposing more than three cooling trays with the same size and the same structure from top to bottom, the periphery of each cooling tray is convex, the bottom of the cooling tray is provided with four holes, and the peripheries of the two holes are provided with lug bosses. The utility model has the advantages of simple structure, convenient manufacture, large heat exchanging areas, good cooling effect on engine oil, and minimal engine oil leakage and water leakage under normal operating conditions.

Description

Machine oil cooler

Technical field

The utility model relates to a kind of machine oil cooler.

Technical background

Machine oil cooler is the oil-cooled special-purpose member that is used for motor car engine.Water-cooling engine oil cooler is to carry out heat exchange by the circulation and the circulation of hot machine oil in the cooler oil pocket of cooling liquid in the cooler water cavity, with the lower higher machine oil of cooling liquid chilling temperature of temperature, be controlled in the comparatively ideal scope with the temperature that guarantees machine oil, thereby guarantee engine operation performance and emission request.

Along with the development and the development of technology of automobile industry, the motor of boosting type high-performance low emission is applied on the automobile more and more, for this reason, need a kind of simple in structure, volume is little, machine oil cooler in light weight, that cooling performance is good is supporting with it.The existing similar products of external advanced country, for example the do motor (satisfying European emission standard) of Bayerische Motorne Werke Aktiengeellschaft's exploitation of certain research of Germany just has such machine oil cooler, but does not domesticly still have this series products.

Summary of the invention

To be solved in the utility model is that existing machine oil cooler heat exchange area is little, the technical problem of cooling effect difference.

Machine oil cooler described in the utility model has the cavity more than 2 in a housing, one is oil pocket in any two adjacent cavitys, and another is a water cavity; All oil pockets communicate with an oil-feed path, a fuel-displaced path respectively; All water cavities go out water passage with a water inlet path, respectively and communicate.

As to improvement of the present utility model, described machine oil cooler is formed by stacking by the coolship more than 3 is upper and lower;

The structure of coolship is: the peripheral projection of coolship; Have four holes in the bottom of coolship, the periphery in two holes has boss therein;

The peripheral projection of a following coolship is close to the outer surface of a superimposed coolship thereon; Should be up and down cavity between two coolships be oil pocket or water cavity; And

Two boss on the following coolship are connected on respectively on the hole of two no boss of periphery on the top coolship; Four groups have formed the oily path of turnover, water inlet and outlet path at the boss of the periphery in same axial hole respectively;

Four holes, bottom on the coolship of the superiors are blocked.

As the utility model is further improved, the peripheral projection of described coolship is outward-dipping, in the periphery of a coolship below a top coolship embeds.

For coolship recited above, its size, structure can be identical.

For coolship recited above, available aluminum alloy material is made.

For any machine oil cooler recited above, can be provided with in described oil pocket and/or water cavity can increase heat diffusion area and delay machine oil or the radiating fin of the mobile speed of water.

The beneficial effects of the utility model: 1, simple in structure, easily manufactured; 2, heat exchange area is big, to the machine oil good cooling results; 3, machine oil and water leak minimum in normal operation.

Embodiment

The utility model is described in further detail below in conjunction with embodiment.

Embodiment 1

Among Fig. 1,2,3,4

cavitys

5,6,7,8 are arranged in housing 1,

cavity

5,7 is an oil pocket, and

cavity

6,8 is a water cavity, and one is oil pocket in any two adjacent cavitys, and another is a water cavity;

Oil pocket

5,7 communicates with oil-feed path 9 by the hole on the oil-feed path 9 10,11, communicates with fuel-displaced path 12 by the hole on the fuel-displaced path 12 13,14;

Water cavity

6,8 communicates with the path 2 of intaking by the

hole

3,4 of water inlet on the path 2, by go out on the water passage 15

hole

16,17 with go out water passage 15 and communicate.

Embodiment 2

Upper and lower being formed by stacking of coolship that machine oil cooler shown in Fig. 4,5,6,7 is identical by 8 sizes, structure, make with aluminum alloy material.

The structure of coolship is as shown in Fig. 8,9,10.The periphery of coolship is a projection 21; Have four
