Part or other parts.
As shown in Figures 1 and 2, according to a kind of oil cooler of the specific embodiment of the invention, including the He of connection end cap 1
External cooling core 2, wherein, connection end cap 1 has the first installation end face a and the second installation end face b, and first, which installs end face a, is used for
On the body of engine, external cooling core 2 is arranged on the second installation end face b, and the oil cooler is only by designing
Vertical external cooling core 2, it is not necessary to the placement space of cooling core is cast, processed on body, also not redesign cooling core
In the water jacket of body, the lateral dimension of engine can be reduced so that complete machine characteristics of compact layout, the housing construction technique letter of engine
It is single, the heat exchange place of machine oil and coolant is formed furthermore with the oil cooler shell itself, improves machine oil cooling effect.
As shown in Figures 3 and 4, connection end cap 1 first installation end face a be provided with machine oil import 11, machine oil outlet 12, it is cold
But liquid import 13 and cooling liquid outlet 14, machine oil import 11 and machine oil outlet 12 are used for and the main oil of machine oil on the body of engine
Road is connected, and cooling liquid inlet 13 and cooling liquid outlet 14 are used for connecting with the coolant circulation system on the body of engine.Outside
Putting the inside of cooling core 2 has coolant circulation chamber and oil circulation passage (not shown in figure, compared with technology), external cold
But core 2 be arranged on connection end cap 1 the second installation end face b it is upper (referring to Fig. 2), coolant circulation chamber and cooling liquid inlet 13 and
Cooling liquid outlet 14 connects, and is back to by the coolant of external cooling core 2 by cooling liquid outlet 14 in the body of engine
Coolant circulation system, oil circulation passage and machine oil import 11 and machine oil outlet 12 connected, and the high temperature oil in body is led to
Cross after machine oil import 11 cools down into external cooling core 2 and export 12 lubricating oil being back in the body of engine further through machine oil
System.Connection end cap 1 can use casting aluminium material, in light weight.
As a kind of preferred embodiment, machine oil import 11 and machine oil export 12 end portions for being located at the first installation end face a,
Cooling liquid inlet 13 and cooling liquid outlet 14 are located at the upper part of the first installation end face (referring to Fig. 4).Second installation end face b positions
In the upper part of connection end cap 1 (referring to Fig. 3), the inside of connection end cap 1 is provided with upper oil-piping 111 and lower oil-piping 121 (ginseng
See Fig. 4), oil circulation passage exports 12 pairs with machine oil import 11 and machine oil respectively by upper oil-piping 111 and lower oil-piping 121
It should connect.External cooling core 2 has the 3rd installation end face (referring to Fig. 2) for coordinating installation with the second installation end face b, external cooling
Oil circulation passage in core 2 is connected with upper oil-piping 111 and lower oil-piping 121 respectively by machine oil end face interface, specifically,
The interface connected with the upper end of upper oil-piping 111 and lower oil-piping 121 respectively is provided with the second installation end face b (to mark in figure
For 151 and 152), correspondingly, it is provided with the 3rd installation end face of external cooling core 2 and the both ends of oil circulation passage is connected
Interface, when coordinating installation with the second installation end face in the 3rd installation end face of external cooling core 2, interface docks with sealing joint
(machine oil end face interface) realizes the circulation passage of machine oil.It is different from the circulation of machine oil for the circulation style of coolant, specifically,
The cavity 16 of indent is provided with the second installation end face b middle part, cavity 16 penetrates with cooling liquid outlet 14, in addition, cooling
Liquid import 13 (on the first installation end face a) insertion circulates the entrance point pair of chamber to the second installation end face b and with coolant
Be connected together, namely cooling liquid inlet 13 with inside external cooling core 2 coolant circulation chamber entrance point using it is similar with
The form of machine oil end face interface, which is realized, to be connected, and the port of export of coolant circulation chamber connects (with coolant not going out with cavity 16
Mouth 14 docks), now, there is substantial amounts of coolant can be cooled down in itself to connection end cap 1 in the inside of connection end cap 1,
The purpose so designed is exactly the coolant inside connection end cap 1 while can carry out heat exchange with the machine oil in upper and lower oil pipe,
The clearing house being not limited to inside external cooling core 2, it is bright equivalent to the heat exchange place for expanding machine oil and coolant, cooling effect
It is aobvious to improve.
Certainly, special-shaped seal ring 17, special-shaped seal ring be must be provided between the second installation end face b and the 3rd installation end face
17 entrance points for being used for circulating machine oil end face interface, cavity and coolant chamber seal, and avoid oil mixing with water.
In addition, second installation end face b on be provided with connected with cooling liquid inlet 13 and cavity 16 split channel 18 (referring to
Fig. 3), the size of split channel 18 designs as needed, can adjust the water of the coolant into external cooling core 2.Point
Circulation road 18 can be shunted to the engine coolant for flowing through cooler, and the unwanted unnecessary coolant of cooler is passed through
This passage is flowed directly in body water jacket, avoids whole coolants from all producing huge water resistance by external cooling core 2, and
Influence the cooling effect of engine body.Further, position can set one-way pressure-limit valve at machine oil import 11, can limit into
Enter the engine oil pressure in external cooling core 2, it is ensured that safety, unnecessary machine oil return to body by discharge orifice 19 (referring to Fig. 4).
In a word, the oil cooler that the present embodiment provides is by designing independent external cooling core 2, it is not necessary on body
The placement space of cooling core is cast, processed, also not redesign water jacket of the cooling core in body, the transverse direction of engine can be reduced
Size, and installation site is more flexible so that and complete machine characteristics of compact layout, the housing construction technique of engine are simple；Should in addition, utilizing
The external cooling core and connection end cap 1 of oil cooler form the heat exchange place of machine oil and coolant simultaneously, plus external cold
But the number of chips of in-core can arbitrarily increase, while can borrow air-cooled, can effectively improve cooling effectiveness.
The description of the foregoing specific illustrative embodiment to the present invention is to illustrate and the purpose of illustration.These descriptions
It is not wishing to limit the invention to disclosed precise forms, and it will be apparent that according to above-mentioned teaching, can be much changed
And change.The purpose of selecting and describing the exemplary embodiment is that explain that the certain principles of the present invention and its reality should
With so that those skilled in the art can realize and utilize the present invention a variety of exemplaries and
Various chooses and changes.The scope of the present invention is intended to be limited by claims and its equivalents.
