Abstract
The utility model relates to an embedded oil cooler of an engine, solving the problem of the unsmooth flow or block of the oil in the oil cooler since the impurity of the oil could deposit or stick in the plate-fin cooler core. The embedded oil cooler comprises a cover shell and a plate-fin cooler core. The cover shell is in a rectangle box cover shape. An oil inlet and an oil outlet are separately arranged on the cover shell. The plate-fin cooler core is arranged on the internal side of the cover shell. The cover shell is also provided with a T-shaped bypass oil duct, wherein the horizontal oil duct is a step-hole oil duct. The small port of the step-hole oil duct is communicated with the oil inlet. The inside of the big port of the step-hole oil duct is in turn provided with a bypass valve, a spring and a sealing piece from inside to outside. The vertical oil duct in the T-shaped oil duct is a bypass oil port. After the oil cooler core is blocked by the impurity, the oil with high pressure can overcome the elastic force of spring to jack up the bypass valve, and the oil can flow smoothly from the bypass oil duct to the main oil duct of the machine, and therefore, the engine can still be operated normally within a certain time when the oil cooler core fails to perform normally.
Description
Technical field
The utility model relates to the engine motor oil cooler.
Background technique
At present, motor adopts machine oil cooler more and more general, no matter be embedded machine oil cooler, or free-standing machine oil cooler, the working principle basically identical: the higher machine oil of temperature is by being in the strip-fin oil cooler core in the water cavity, machine oil carries out heat exchange by the current in strip-fin oil cooler core and the water cavity, thereby reaches the purpose that reduces oil temperature.But after long-time the use, the impurity in the machine oil may precipitate or be bonded at the strip-fin oil cooler in-core and cause engine oil flow not smooth or obstructed, causes engine oil pressure low or do not have pressure, influences the generation that serious meeting causes motor Bearing score phenomenon.
Summary of the invention
For the impurity that solves in the machine oil may precipitate or be bonded at the strip-fin oil cooler in-core, cause the not smooth or obstructed problem of engine oil flow in the machine oil cooler, the utility model provides a kind of motor with bypass valve embedded machine oil cooler.
Concrete structural design scheme is such:
The embedded machine oil cooler of motor comprises covers shell and strip-fin oil cooler core;
Described lid shell is a rectangle lid shape, and its both sides, middle part are respectively equipped with filler opening and oil outlet, and lid shell inner side surface is provided with the strip-fin oil cooler core, and the import of strip-fin oil cooler core is being communicated with filler opening and the oil outlet that covers on the shell respectively with outlet;
Also be provided with a T pictographic element of a pictophonetic oil canal on the lid shell at filler opening place, horizontal oil duct in the T pictographic element of a pictophonetic oil canal is the step hole oil duct, the portlet of step hole oil duct is being communicated with filler opening, is provided with bypass valve, spring and sealed piece in the large port of step hole oil duct from inside to outside successively; Vertical oil duct in the T pictographic element of a pictophonetic oil canal is the bypass hydraulic fluid port.
Described sealed piece is a bolt.
The utility model is provided with the bypass oil duct near the filler opening of housing, the outlet of bypass oil road communicates with the motor main oil gallery, and a safeguarding mechanism of being made up of spring and bypass valve is set in the middle of the bypass oil duct.When the contamination precipitation in the machine oil or be bonded at the strip-fin oil cooler in-core when causing engine oil flow not smooth or obstructed, machine oil with elevated pressures can overcome the elastic force jack-up bypass valve of spring, enter the motor main oil gallery smoothly, thereby oil pressure maintains the purpose of safe condition when reaching engine operation.
The beneficial effects of the utility model are after motor installs this kind of machine oil cooler additional, when improving the motor operational safety, can not stop up the catastrophe failure that the motor Bearing score takes place because of machine oil cooler.
Description of drawings
Fig. 1 is the utility model structural representation,
Fig. 2 is the plan view of Fig. 1,
Fig. 3 is the A-A partial sectional view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Embodiment:
Referring to Fig. 1, Fig. 2 and Fig. 3, the embedded machine oil cooler of motor comprises covers shell 1 and strip-fin oil cooler core 2;
Also be provided with a T pictographic element of a pictophonetic oil canal 5 on the lid shell at filler opening 6 places, horizontal oil duct in the T pictographic element of a pictophonetic oil canal 5 is the step hole oil duct, the portlet of step hole oil duct is being communicated with filler opening 6, is provided with bypass valve 4, spring 3 and sealed piece in the large port of step hole oil duct from inside to outside successively; Vertical oil duct in the T pictographic element of a pictophonetic oil canal 5 is a bypass hydraulic fluid port 8; Sealed piece is a bolt.
Be cast with the special-purpose water cavity of the cooler that communicates with the body water channel on the engine body, water cavity is that rectangular is arranged along the body length direction, is convenient to the abundant exchange of heat, and the utility model is by covering shell 1 usefulness bolt in engine body cooler water cavity.
During the cooler proper functioning, the lower current of temperature enter cooler core place water cavity from water cavity near the water channel of body front end, carry out exchange heat by strip-fin oil cooler core 2 and machine oil, the heat of machine oil is taken away, and current flow to the water channel outflow of water cavity near body rear end along the body length direction; Enter from filler opening 6 after the oil temperature reduction of strip-fin oil cooler core 2, flow out from oil outlet 7, and enter the motor main oil gallery, guarantee that engine running is in shape.
After being stopped up by impurity in the strip-fin oil cooler core 2, the elastic force that machine oil with elevated pressures can overcome spring 3 backs down bypass valve 4, flow to bypass hydraulic fluid port 8 smoothly from T pictographic element of a pictophonetic oil canal 5 and enter the body main oil gallery, thereby when reaching the machine oil cooler core and breaking down and motor still can be kept the purpose of normal operation within a certain period of time.
Claims (2)
1, the embedded machine oil cooler of motor comprises and covers shell and strip-fin oil cooler core, it is characterized in that:
Described lid shell is a rectangle lid shape, and its both sides, middle part are respectively equipped with filler opening and oil outlet, and lid shell inner side surface is provided with the strip-fin oil cooler core, and the import of strip-fin oil cooler core is being communicated with filler opening and the oil outlet that covers on the shell respectively with outlet;
Also be provided with a T pictographic element of a pictophonetic oil canal on the lid shell at filler opening place, horizontal oil duct in the T pictographic element of a pictophonetic oil canal is the step hole oil duct, the portlet of step hole oil duct is being communicated with filler opening, is provided with bypass valve, spring and sealed piece in the large port of step hole oil duct from inside to outside successively; Vertical oil duct in the T pictographic element of a pictophonetic oil canal is the bypass hydraulic fluid port.
