Description
Technical field
The utility model relates to the automobile oil cooler, is used for the cooling that circulates of gearbox or in-engine machine oil is referred in particular to the machine oil cooler of water route and oil circuit integrated molding, specifically a kind of chip structure of integrated type machine oil cooler.
Background technique
In the running process of automobile, its engine motor oil, speed changer machine oil can produce a large amount of heats at work, cause machine oil overheated, therefore must adopt water-cooled or air-cooled the cooling by machine oil cooler, and its temperature is controlled in the suitable scope.
Traditional cooler construction is generally plate and fin type, tubular fin type, disc type.All oil passageway all is immersed in the cooling water on its structural design, all needs for cooling water designs a cavity, the volume that takes up room is big, and cooling water heat absorbing property surplus causes the waste of cold side heat dispersion simultaneously.For high-power, high performance motor, the oil cooler and the contradiction between the compact motor that take large space are more outstanding.The design of integrated type cooler can overcome the deficiency of conventional cooler.Simultaneously, it also can be with the heat exchange of other industry.
Summary of the invention
To be solved in the utility model is that existing cooler volume is big, inefficient problem, the technological scheme that addresses the above problem employing is: the chip structure of integrated type machine oil cooler, every chip is made of last chip and following chip, multi-plate chip overlaps the heat radiation fuse, it is characterized in that every chip all has oil inlet hole, oil outlet and water inlet, osculum; Oil circuit in the turnover oilhole of described every chip and the chip communicates, and the turnover oilhole of adjacent chips seals and conducts; The paddle hole of described every chip and the water route conducting between adjacent chips; Also be provided with spacer ring or stretching boss between the adjacent chips; Adopt flange plug in structure and/or plane involution structure between adjacent last chip and the following chip,, thereby form relatively independent and complete oil circuit in described splicing position peace face apposition position seal welding.
As further improvement of the utility model, can adopt the flange plug in structure separately between adjacent last chip and the following chip.The described chip of going up has identical turnup structure with following chip.Described flange plug in structure is achieved in that the described chip of going up digs into hypotenuse with following chip periphery, and adjacent last chip is pegged graft successively with the hypotenuse of following chip.
Described flange plug in structure can also be achieved in that described flange have external section of top and bottom in the section of connecing, external section of described top is plugged on adjacent last chip or the section of connecing outer wall in the bottom of chip down, and in the splicing position seal welding; External section of described top is than connecing Duan Dayi chip thickness size in the bottom.
Described flange plug in structure has two face of weld at the flange place of chip, thus it chip manufacturing process is had relatively high expectations, but its assembly technology is simple relatively, and its space availability ratio also is very high.Because last chip can be formed by identical a kind of chips welding with following chip, therefore, its required mould is less, and die cost is also lower.
As further improvement of the utility model, also can adopt the plane involution structure separately between adjacent last chip and the following chip, this structure, described chip down can contain the described chip of going up, and also can be that the described chip outside down flushes with the described chip outside of going up.The plane involution structure, because two face of weld all are substantially horizontals, so the requirement of its chip manufacturing process is low relatively, but its assembly technology requires relative complex.Its oily aisle spare and water channel area are unequal, and therefore, space availability ratio is more lower slightly than flange plug in structure, but more help satisfying the requirement of client to the pressure loss.
As further improvement of the utility model, adopt flange to peg graft peace between adjacent last chip and the following chip in the face of closing structure combining, promptly one go up chip or down chip with upper and lower two adjacent following chips or go up to adopt flange plug in structure peace to face between the chip respectively to close structure and be connected.
Further improve again as of the present utility model, in described oil circuit that forms separately by chip and/or water route, be provided with flow-disturbing fin and/or salient point, determine the height of two side canals and the density of fin or stretching step respectively according to the heat radiation requirement of oily side and the heat absorbing property of water side, make full use of the heat absorbing property of cooling water, be used for producing turbulent flow and increase radiating efficiency.
Further improving as of the present utility model, can be series, parallel or series parallel connection mixed form between described oil circuit and the oil circuit.
By above analysis as can be known, the chip structure of integrated type machine oil cooler of the present utility model has gone out independently oily passage and water channel in the cooler indoor design, and structure adopts stacked, and water channel layer and oil duct layer be stack alternately, need not to design in addition cavity.Therefore, for same heat radiation requirement, integrated type cooler occupation space volume is littler, and structure is more compact, and owing to there is not the requirement of cavity, can reduce the labyrinth of engine body, and cooler is easier for installation.
