Description

Oil cooler of electric driving system of electric automobile

Technical Field

The utility model relates to an oil cooler especially relates to an electric automobile electric drive system oil cooler.

Background

An oil cooler is a device for accelerating the heat dissipation of lubricating oil to keep the temperature at a lower temperature. In a high-performance and high-power intensified engine, an oil cooler must be installed due to a large thermal load. The oil cooler is arranged in the lubricating oil path and works in the same principle as the radiator.

The oil cooler is installed in power mechanical equipment, and the lubricating oil and cooling liquid are subjected to heat exchange through the oil cooler, so that the temperature of the lubricating oil is effectively controlled, and the lubricating oil is ensured to work under proper viscosity. At present, the traditional structure adopts a plate-fin laminated structure, and the production of the part relates to a multi-step process, wherein the processes of brazing and the like are complex and the cost is high. And the oil cooler is arranged outside the power assembly as an independent structure, often leads to local protrusion of the structure, and causes influence on the adaptation of the multi-vehicle type platform of the power assembly.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an electric automobile electric drive system oil cooler for overcoming the defects of the prior art.

The purpose of the utility model can be realized through the following technical scheme:

the utility model provides an electric automobile electric drive system machine oil cooler, includes the cooler body, be equipped with oil inlet and the oil-out that is used for advancing, produces oil respectively on the cooler body, still be equipped with the sinuous engine oil groove that is used for increasing the fluidity of lubricating oil on the cooler body, be equipped with a plurality of humps that are used for increasing lubricating oil and engine oil groove area of contact in the sinuous engine oil groove.

Furthermore, the cooler body is also provided with a separating part for separating the direction of the engine oil outlet flow passage in an integrated forming mode.

Further, the shape of the convex peak is cylindrical.

Further, the shape of the convex peak is conical.

Further, the shape of the convex peak is a blade shape.

Further, the shape of the convex peak is corrugated.

Compared with the prior art, the utility model has the advantages of it is following:

(1) the utility model discloses set up and arrange a plurality of oil circuits in the engine oil groove on the cooler body, when taking into account the oil circuit reposition of redundant personnel, increase the flow of lubricating oil.

(2) The utility model discloses set up and increase the design of hump in the machine oil groove on the cooler body, increase heat exchange efficiency.

Drawings

To further clarify the above and other advantages and features of various embodiments of the present invention, a more particular description of various embodiments of the invention will be rendered by reference to the appended drawings. It is appreciated that these drawings depict only typical embodiments of the invention and are therefore not to be considered limiting of its scope. Also, the relative positions and sizes of the respective portions shown in the drawings are exemplary, and should not be understood as uniquely determining positional or dimensional relationships between the respective portions.

Fig. 1 is a schematic view of the overall structure of the present invention;

FIG. 2 is a schematic view of the flow direction of the engine oil of the present invention;

in the figure, 1 is a cooler body, 2 is an oil inlet, 3 is an oil outlet, and 4 is a convex peak.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, of the embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts shall fall within the protection scope of the present invention.

Examples

As shown in fig. 1, the utility model discloses an overall structure schematic diagram includes cooler body 1 in the picture, and still integrated into one piece is equipped with the partition portion that is used for separating machine oil outlet flow channel direction on the cooler body 1, is equipped with oil inlet 2 and the oil-out 3 that is used for advancing, producing oil respectively on the cooler body 1, still is equipped with the mobile sinuous machine oil groove that is used for increasing lubricating oil on the cooler body 1, and sinuous machine oil inslot is equipped with a plurality of humps 4 that are used for increasing lubricating oil and machine oil groove area of contact.

As shown in fig. 2, the utility model discloses an engine oil flow direction sketch map, motor casing integrated oil cooler structure in this structure specifically is to arrange the oil groove in the periphery of motor water jacket casing, and the oil pump carries lubricating oil to the oil groove entry, and the oil groove is inside to adopt the labyrinth design, increases the flow of lubricating oil, and final lubricating oil shunts the motor both ends. A large number of convex peaks are extended in the engine oil groove, the contact area of lubricating oil and the engine oil groove is increased, and the heat exchange efficiency of the lubricating oil and the cooling liquid is further improved.

The design of the oil cooler is characterized in that:

1. a plurality of oil paths are arranged in the engine oil groove, and the flow of lubricating oil is increased while oil path shunting is considered. This patent includes other possible oil path diversion arrangements

2. The design of convex peaks is added in the oil groove, and the heat exchange efficiency is increased. The peaks may be cylindrical, conical, knife-edged, corrugated, etc. in other shapes.

On the oil cooler integrated to motor casing, when compromise lubricating oil cooling function, cancelled traditional oil cooler, obvious reduce cost. Structurally, the whole machine has no obvious protrusion, is more compact, and obviously improves the space adaptability of the power assembly on a platform of multiple vehicle types.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily think of various equivalent modifications or replacements within the technical scope of the present invention, and these modifications or replacements should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
