Description of drawings
The accompanying drawing that consists of a part of the present invention is used to provide a further understanding of the present invention, and illustrative examples of the present invention and explanation thereof are used for explaining the present invention, do not consist of improper restriction of the present invention.In the accompanying drawings:
Fig. 1 shows the schematic representation of the oil temperature control structure of one embodiment of the present of invention; And
Fig. 2 shows the flow chart of the oil temperature controlling method of using the oil temperature control structure among Fig. 1.
Embodiment
Below in conjunction with accompanying drawing embodiments of the invention are elaborated, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.
The schematic representation of the oil temperature control structure of one embodiment of the present of invention has been shown among Fig. 1.There is shown oil cooler 1, this oil cooler 1 is communicated with cooling water, enter hot lubricant oil that pipeline 2 enters oil cooler 1 by the water quench (marking with arrow the figure) that enters and flow out from oil cooler 1 side by deep fat, and then flow out pipeline 3 by cold oil and flow out.Oil temperature control structure of the present invention also comprises: bypass line 4 is communicated with described deep fat and enters pipeline 2 and cold oil outflow pipeline 3; In the controlling device that bypass line 4 is provided with, the flow of the lubricant oil of bypass line is flow through in controlling device control, can be standard-sized sheet or full cut-off, also can be a certain intermediateness.
Preferably, flow out pipeline 3 at cold oil and be provided with temperature transducer 6, the controlling device that arranges at bypass line 4 comprises solenoid valve 5 (in the modulating valve a kind of, also can be other kind control units, such as mortor operated valve) and angle valve 7.Deep fat enters between pipeline 2 and the bypass line 4 and is connected by three-way valve 8.The temperature transducer that is arranged on the cold oil outflow pipeline 3 is delivered to purpose digital temperature controller with temperature signal.This purpose digital temperature controller is being monitored cold oil and is being flowed out the oil temperature in the pipeline 3 and be electrically connected solenoid valve 5, according to the oil temperature situation, and the opening degree of control solenoid valve 5.For example, when the temperature of temperature transducer 6 detection gained is equal to or higher than setting value, close modulating valve 5, when the temperature of temperature transducer 6 detection gained is lower than setting value, open modulating valve 5.In addition, angle valve 7 can manually be controlled the opening degree of bypass line 4 as the additional setting of solenoid valve 5.
Preferably, also can be provided with angle valve 7 or ball valve at bypass line 4 separately, directly by manually regulating the aperture of angle valve 7 or ball valve, and then the flow of the lubricant oil of bypass line 4 is flow through in control.
Referring to shown in Figure 2, the oil temperature controlling method of the oil temperature control structure shown in Fig. 1 is as follows:
Detecting step, temperature transducer 6 detects the oil temperature on the cold oil outflow pipeline 3, oil temperature signal is passed to purpose digital temperature controller (temp controller a kind of, not shown, can be various types of controllers, for example other have the element of acknowledge(ment) signal, transmission of signal and control function, controller on the air-conditioning mainboard etc.).
Comparison step, purpose digital temperature controller have been set what a preset temperature value (can get 45 ℃) in advance, with numerical value and the preset temperature value of the oil temperature signal that obtains.
The control step, the comparative result that draws according to comparison step, control is flow through and is communicated with the flow that deep fat enters the lubricant oil in the bypass line 4 that pipeline 2 and cold oil flows out pipeline 3.
Preferably, in the control step, if the numerical value of the oil temperature signal that obtains is equal to or higher than setting value, solenoid valve (or other kind control units, such as mortor operated valve) 5 be failure to actuate, remain closed, if the numerical value that obtains is lower than setting value, purpose digital temperature controller just transfer control signal to solenoid valve 5, make its action, open bypass line 4, deep fat is entered pipeline 2 from deep fat import cold oil outflow pipeline 3 by bypass line 4, mix with outlet cold oil, the outlet oil temperature is adjusted near the setting value.
Preferably, also have a regulating step, be lower than the degree of setting value according to oil temperature, the angle valve of manual tune on described bypass line 4 (or other kind control units, such as ball valve) 7, to regulate the aperture of bypass line 4.Like this, if solenoid valve 5 lost efficacy, can also be by regulating or close this angle valve 7 and control deep fat, thus avoid since solenoid valve 5 when losing efficacy a large amount of deep fats enter oil outlet end and cause oil outlet temperature too high, played secondary and regulated the effect of protecting.Preferably, such as: when oil outlet temperature reaches 40 ℃, can the standard-sized sheet angle valve, temperature can half opened angle valve in the time of 42 ℃ to 43 ℃.
According to oil temperature control structure of the present invention, have following beneficial effect:
Degree of regulation is high, and oil temperature is slowly changed, and remains near the setting value always, has avoided the situation of the frequent start-stop of water pump.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
