Abstract
The utility model discloses an engine oil cooling device, which comprises an engine oil cooler, wherein the oil inlet of the engine oil cooler is connected with an oil inlet pipe; the oil outlet of the engine oil cooler is connected with an oil outlet pipe; the tail end of the oil outlet pipe is communicated with a main oil duct; the oil inlet pipe is communicated with the main oil duct via a by-pass pipe; the by-pass pipe is provided with a control valve; the control valve is controlled by a controller to be switched on and off. When an engine disclosed by the utility model is used, most engine oil does not pass through the engine oil cooler when the engine is started, a car can be quickly warmed up, and time and fuel oil are saved; under the low-load working condition or in an alpine region, due to the fact that the most low-temperature engine oil does not pass through the engine oil cooler, the temperature of the engine oil is high, thereby being favorable for lowering friction loss power, and saving fuel oil.
Description
Technical field
The utility model relates to a kind of machine oil cooler of engine.
Background technique
Machine oil cooler is a kind ofly to accelerate lubricating oil heat radiation and make it keep the device of lower temperature.The object of this device is installed, and is to raise and cause lubrication to weaken for fear of oil temperature.According to the difference of cooling medium, machine oil cooler can be divided into two kinds of air-cooled and water-cooleds.The air-cooled air-flow producing while utilizing Vehicle Driving Cycle carries out cooling to machine oil.Water-cooled is arranged in the hydroecium of radiator or in the cooling water system of motor conventionally, by and cooling water between heat exchange, carry out cooling to high temperature oil.
In prior art, as long as just cooling machine oil always of engine running machine oil cooler, this kind of cooling unit has following shortcoming: when starting the hot car time longer, both wasted the time, also wasted fuel oil; At running on the lower load or at extremely frigid zones, oil temperature is lower, and engine oil viscosity is bigger than normal, and the surface friction drag of part friction surface also just increases, and fricting loss power is large.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of machine oil cooler of engine.
For solving the problems of the technologies described above, the utility model comprises machine oil cooler, the filler opening of machine oil cooler is connected with oil inlet pipe, the oil outlet of machine oil cooler is connected with oil outlet tube, oil outlet tube end is communicated with main oil gallery, it is characterized in that described oil inlet pipe is communicated with by bypass tube with main oil gallery, on described bypass tube, control valve is installed, described control valve is by its switch of controller control.
Described control valve is normally closed solenoid valve, and it is electrically connected with second source, and the current supply circuit of control valve is provided with the relay of controlling current supply circuit break-make; Described relay is electrically connected with the first power supply, controller, the break-make of the switch of controller control relay and then control control valve current supply circuit.
On described main oil gallery, temperature transducer is installed, the signal output part of temperature transducer is electrically connected with controller.
Described controller is ECU or single-chip microcomputer.
Adopt after said structure, when oil temperature is during lower than setting temperature, controller makes the energising of control valve current supply circuit by control relay, control valve is opened, because the resistance of machine oil cooler is larger, most of machine oil directly enters main oil gallery by bypass tube, and most of machine oil is cooling without machine oil cooler.When oil temperature is during higher than setting value, controller makes the power-off of control valve current supply circuit by control relay, and control valve is closed, and machine oil all enters machine oil cooler by oil inlet pipe and carries out coolingly, and cooled machine oil enters main oil gallery through oil outlet tube again.Use motor of the present utility model, when startup, because most of machine oil is without machine oil cooler, hot car is very fast, saves time, capable of saving fuel oil; At running on the lower load or extremely frigid zones, because the machine oil major part of low temperature is without machine oil cooler, oil temperature is higher, is conducive to reduce fricting loss power, capable of saving fuel oil.
Brief description of the drawings
Below in conjunction with the drawings and the specific embodiments, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, machine oil cooler of engine comprises machine oil cooler 8, the filler opening of machine oil cooler 8 is connected with oil inlet pipe 9, the oil outlet of machine oil cooler 8 is connected with oil outlet tube 7, oil outlet tube 7 ends are communicated with main oil gallery 10, and oil inlet pipe 9 is communicated with by bypass tube 6 with main oil gallery 10, and control valve 5 is installed on bypass tube 6, control valve 5 is controlled its switch by controller 2, and controller 2 is ECU or single-chip microcomputer.In the present embodiment, control valve 5 is normally closed solenoid valve, and it is electrically connected with second source 4, and the current supply circuit of control valve 5 is provided with the relay 3 of controlling current supply circuit break-make; The input end of relay 3 is electrically connected with the first power supply 1, controller 2, the break-make of the switch of controller 2 control relays 3 and then control control valve 5 current supply circuits.Temperature transducer 11 is installed on main oil gallery 10, and the signal output part of temperature transducer 11 is electrically connected with controller 2.
When oil temperature is during lower than setting temperature, temperature transducer 11 outputs signal to controller 2, controller 2 sends instruction control relay 3 and makes control valve 5 current supply circuit energisings, control valve 5 is opened, because the resistance of machine oil cooler 8 is larger, most of machine oil directly enters main oil gallery 10 by bypass tube 6, and most of machine oil is cooling without machine oil cooler 8.When oil temperature is during higher than setting value, temperature transducer 11 outputs signal to controller 2, controller 2 sends instruction control relay 3 and makes control valve 5 current supply circuit power-off, control valve 5 is closed, machine oil all enters machine oil cooler 8 by oil inlet pipe 9 and carries out coolingly, and cooled machine oil enters main oil gallery 10 through oil outlet tube 7 again.Use motor of the present utility model, when startup, because most of machine oil is without machine oil cooler 8, hot car is very fast, saves time, capable of saving fuel oil; At running on the lower load or extremely frigid zones, because the machine oil major part of low temperature is without machine oil cooler 8, oil temperature is higher, is conducive to reduce fricting loss power, capable of saving fuel oil.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model.Previous embodiment has been described in detail the utility model, and for a person skilled in the art, its technological scheme that still can record aforementioned each embodiment is modified, or part technical characteristics is wherein equal to replacement.In every case within inventive concept scope of the present utility model, any amendment of making, be equal to replacement, improvement etc., within being all included in protection domain of the present utility model.
