As the further restriction to aforesaid way, the line of the arranged direction of described heat exchange web and oil inlet hole and oil outlet be arranged in parallel.
As to another kind of restriction the of the present invention, in hollow cavity, be provided with chip flute.
As the restriction to aforesaid way, described hollow cavity is square, and described chip flute is arranged on the corner point of oil inlet hole and oil outlet line one side.
As the further restriction to aforesaid way, described chip flute is hook hand shape.
As the further restriction to aforesaid way, the heat exchange web that described chip flute is connected by an end that is positioned at corner point and hollow cavity sidewall, surround with the non-sealing of sidewall that surrounds the hollow cavity of this angle point.
The present invention also has a kind of restriction, and described body is comprised of the main body of the hollow cavity end opening setting, that have indent, the cover plate that sealing is fixed on the body openings place.
As the restriction to aforesaid way, one-body molded being connected in bottom surface of described heat exchange web and main body.
Owing to having adopted technique scheme, the present invention compared with prior art, obtained technological progress is:
1, body is fixed on the water-jacket outer wall, when machine oil flows from oil inlet hole along passage to oil outlet, utilize the heat exchange web to absorb the heat of machine oil, and be passed to cooling liquid in the water jacket, so that machine oil is cooled off, in the body without independent water channel design, avoided body to break down or quality not good and cause the phenomenon of fluid mixing;
2, each heat exchange web be arranged in parallel, and the horizontal area everywhere of the passage of adjacent two heat exchange webs formation is equated, guarantees that the machine oil circulation is smooth and easy;
3, oil inlet hole and oil outlet are separately positioned on the two ends of hollow cavity overall dimensions line, guarantee that machine oil flows into oil outlet from oil inlet hole and has maximum mobile distance, and machine oil is fully cooled off;
4, the chip flute that arranges in the hollow cavity is used for collecting the impurity of machine oil, makes contamination precipitation in interior;
5, hollow cavity is square, is convenient to the body casting, is convenient to simultaneously body and is fixed on the water-jacket outer wall; Chip flute is arranged on the corner point of oil inlet hole and oil outlet line one side in addition, and when machine oil flows out from passage, when getting to the body sidewall, impurity can fall into chip flute under Action of Gravity Field;
6, chip flute adopts hook hand shape, and when making impurity in the chip flute rotary current is moving under the impact of machine oil, machine oil forms eddy current in chip flute, and then so that impurity can not taken out of chip flute by fluid;
7, the heat exchange web that is connected by an end that is positioned at corner point and hollow cavity sidewall of chip flute, surround with the non-sealing of sidewall that surrounds the hollow cavity of this angle point, when machine oil is got to the sidewall that surrounds chip flute along channel flow, machine oil flows to oil outlet under pressure, and the impurity in the machine oil is lowered to chip flute at action of gravitation;
8, body is comprised of main body and the cover plate of opening, and main body and cover plate adopt respectively casting, impact briquetting, is convenient to body and makes moulding; In addition, the bottom surface of heat exchange web and main body is one-body molded, equally also is convenient to heat exchange web casting.
In sum, the present invention has characteristics simple and compact for structure, with low cost, as to be fit to production in enormous quantities.

Embodiment
Embodiment
A kind of cooler for engine oil that the present embodiment relates to such as Fig. 1, Fig. 2, shown in Figure 3, comprises body 9, and body 9 is the tetragonal body structure, is comprised of front opening and the cover plate 8 that has the main body 1 of hollow cavity and be fixed on main body 1 opening.Main body 1 bottom is fixed on the outer wall of engine water jacket, and front-end face is for installing end face 3.The lower right-hand corner that end face 3 is installed is provided with oil inlet hole 4, and place, the upper right corner is provided with oil outlet 5, and this is arranged so that oil inlet hole 4 and oil outlet 5 are arranged on the two ends of hollow cavity overall dimensions line.If the end surface shape of hollow cavity is circular, 5 of oil inlet hole 4 and oil outlets are arranged on the two ends of this circular diameter.The upper left corner and place, the lower right corner that end face 3 is installed also are respectively equipped with mounting hole 7.Cover plate 8 is fixed on the main body 1 in mounting hole 7 places through bolt, in addition, also can adopt sealant sealing in cover plate 8 and installation end face 3 contact position, to realize better sealing effect.
Be provided with a plurality of in the hollow cavity and the integrated heat exchange web 2 of main body 1 bottom inwall, it is divided into hollow cavity the path 10 of a plurality of connection oil inlet holes 4 and oil outlet 5.Each heat exchange web 2 be arranged in parallel, and arranged direction is parallel with the line of oil outlet 5 with oil inlet hole 4.In the present embodiment, be positioned at the heat exchange web 2 on the hollow cavity diagonal, oil inlet hole 4, oil outlet 5 are pointed to respectively in the two ends that are the longest heat exchange web 2 of length, when machine oil when the path 10 that surrounds of the heat exchange web 2 that is adjacent of heat exchange web 2 flows thus, machine oil can be beaten on the sidewall of hollow cavity, can not flow directly in the oil outlet 5.
In addition, be positioned at the hollow cavity right side the lower wall of heat exchange web 2 and the hollow cavity of below corner point connect firmly, in order to distinguish the different of this heat exchange web 2 and other heat exchange web 2 functions, this is referred to as right lower side heat exchange web 21 again for we.The sidewall at place, the hollow cavity lower right corner is arc-shaped structure 11, the lower end of right lower side heat exchange web 21 links to each other with arc-shaped structure 11, the two nonocclusive zone that surrounds is the chip flute 6 of hook hand shape, be that right lower side heat exchange web 21 had both had the effect identical with other heat exchange webs, consist of simultaneously the marginal texture of chip flute 6, the free end of right lower side heat exchange web 21 and the right side wall of hollow cavity have the opening that enters for impurity.
The manufacturing process of the present embodiment is:
At first main body 1 and the 2 integrated die-casting moulding of heat exchange web, then get out oil inlet hole 4, oil outlet 5 and mounting hole 7 at installation end face 3, end face 3 is installed in milling, then use bolton on main body 1 the stamping forming cover plate of integral body, and seal with sealer in cover plate and installation end face 3 contact position.
The working procedure of the present embodiment is as follows:
The hot machine oil of lubrication system is entered by oil inlet hole 4 in the path 10 of hollow cavity, and heat exchange web 2 can absorb the heat of machine oil, and with heat from main body 1 bottom is passed to cooling liquid in the water jacket, machine oil is cooled off.When machine oil flows out from path 10, when machine oil was got to upper side wall, machine oil can flow into oil outlet 5 along upper side wall, and the impurity in the machine oil is in the drive current downflow of machine oil, can blocking channel 10; When machine oil was got to the right side wall of hollow cavity, machine oil can flow to oil outlet 5 under pressure, and impurity is lowered to chip flute 6 at action of gravitation.If the rotary current under the impact of machine oil of the impurity in the chip flute 6 is moving, because chip flute 6 is hook hand shape, impurity can at chip flute 6 interior formation eddy current, can not driven from chip flute 6 interior outflows by fluid.
