Abstract
The invention discloses a thermostat for an automobile engine. The thermostat comprises a valve main body and is characterized in that the valve main body is of a circular disk shape, is adapted to the internal diameter of a pipeline of an automobile cooling system and is rotatably arranged in the pipeline. The thermostat further comprises a driving element made from memory alloy, wherein the two ends of the driving element are respectively fixed with the inner side of the pipeline and the valve main body, and the driving element is deformed to drive the valve main body to rotate after a coolant in the cooling system reaches a set value. According to the thermostat for the automobile engine, the driving element is formed in a manner that the traditional paraffin is replaced with the memory alloy, the opening direction of a valve is controlled by using the torsional characteristics provided by the memory alloy, and the opening direction of the valve is not consistent with the water flowing direction, so that over 90% of pressure loss can be reduced, and a greater space for the selection of water pump design by users is provided.
Description
Technical field
The present invention relates to the temperature regulator in a kind of cooling system of motor car engine, the thermostat in especially a kind of cooling system pipeline.
Background technique
Thermostat is a thermoregulator strength member in the engine-cooling system; Its height according to cooling water temperature is regulated the water yield that gets into radiator automatically; Change the range of DO of water, to regulate the heat dissipation potential of cooling system, the assurance motor is worked in suitable temperature range.Thermostat must keep the good technical state, otherwise can have a strong impact on the proper functioning of motor.
Thermostat commonly used at present is a waxtype thermostat; When chilling temperature was lower than specified value, the paraffin in the thermostat temperature sensor was solid-state, the thermostat valve kill engine under the effect of spring and radiator between passage; Cooling liquid is carried out short circle in the motor through the water pump return engine.After coolant temperature reaches specified value; Paraffin begins thawing and gradually becomes liquid; Volume increases thereupon that effect makes valve opening to push rod, and at this moment cooling liquid flows back to motor through water pump again via radiator and thermostat valve; Carrying out major cycle, number is the disclosed a kind of thermostat of Chinese patent of CN201650435U like notice of authorization.
In addition; The electric-controlled type thermostat is also arranged, and it is the driving mode that cooperates with electromagnetic coil and armature, replaces paraffin; Through the control of electromagnetic coil being accomplished the keying folding of valve; Control is sensitive, and reliability is high, number is the disclosed a kind of electric-controlled thermostat of Chinese patent of CN202348410U like notice of authorization.
These above-mentioned thermostats, the valve opening and closing direction is consistent with water (flow) direction, because the narrow limitation of this structure itself causes circulating water flow when thermostat, crushing strengthens, cooling capacity reduces.And along with the development of automotive engineering, also increasingly high to the requirement of energy consumption, cooling capacity reduces and directly causes pump power constantly to reduce.
Summary of the invention
Technical problem to be solved by this invention provides and a kind ofly can significantly reduce crushing, improves the thermostat of the motor car engine of cooling capacity.
The present invention solves the problems of the technologies described above the technological scheme that is adopted: a kind of thermostat of motor car engine; Comprise valve body; It is characterized in that; Said valve body is in the form of annular discs, and is adaptive and be arranged on rotationally in the said pipeline with the pipeline internal diameter of automobile cooling system, also comprises the driving element of being processed by memory alloy; The two ends of said driving element are fixed with the inboard and the said valve body of said pipeline respectively, can be out of shape after the cooling liquid of said driving element in said cooling system reaches specified value to drive said valve body rotation.
Symmetry offers positioning hole on the sidewall of said pipeline, is fixed with rotating shaft on the bottom surface of said valve body, and the two ends of said rotating shaft wear in the positioning hole, and rotating shaft can be rotated in positioning hole, and valve body can rotate through rotating shaft thus.
The means of fixation of said driving element, can for, comprise the integrated the first arm and second arm, the end of said the first arm and said pipeline are inboard fixing, the end of said second arm and said valve body are fixed, and have angle between two arms.
Compared with prior art; The invention has the advantages that: driving element is replaced traditional paraffin with memory alloy; The twisting characteristic that utilizes memory alloy to provide comes the control valve opening direction, and the opening direction of valve is no longer consistent with water (flow) direction; Can reduce crushing more than 90%, bigger space is provided for the design alternative of user's water pump.

Fig. 2 is the thermostat opening state schematic representation of Fig. 1.
Embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
Referring to Fig. 1 and Fig. 2, a kind of thermostat of motor car engine comprises valve body 1 and driving element 2.Wherein, Valve body 1 is in the form of annular discs, and adaptive with the pipeline 3 of automobile cooling system, symmetry offers positioning hole 31 on the sidewall of pipeline 3; Be fixed with rotating shaft on the bottom surface of valve body 1; The two ends of rotating shaft wear into rotating in the positioning hole 31 and positioning hole 31 in, thus the relative position of valve body 1 and pipeline 3 fix, and can rotate through rotating shaft when receiving external force.Driving element 2 is processed by memory alloy, is main with the Cu base, like Ti-Ni-Cu or Cu-Al-Be.Driving element 2 comprises integrated two arms, and the end of the first arm 21 and pipeline 3 are inboard fixing, and the end of second arm 22 and valve body 1 are fixing, have angle between two arms.
When chilling temperature was lower than specified value, driving element 2 was in original state, and valve body 1 is parallel with the radial plane of pipeline 3, had sealed the passage between motor and the radiator, and cooling liquid is carried out short circle in the motor, referring to Fig. 1 through the water pump return engine.After coolant temperature reached specified value, driving element 2 began distortion, and the angle between two arms increases; Can promote valve body 1 with an end of second arm 22 of the fixing driving element 2 of valve body 1 thus can rotate through rotating shaft, and no longer shape has a certain degree with the radial plane of pipeline 3 is parallel to make valve body 1, valve body 1 unlatching; At this moment cooling liquid is via radiator and thermostat; Flow back to motor through water pump again, carry out major cycle, referring to Fig. 2.
In addition, electronic control unit (ECU) can be set also on the thermostat, receive the signal of the temperature transducer that is provided with in the pipeline 3, thereby thereby come control driving component 2 opening/shutting valve main bodys 1 through the control electronic controller.
The above is merely preferred implementation of the present invention, should be pointed out that for those of ordinary skill in the art, not breaking away under the principle prerequisite of the present invention, can also make various deformation and improvement, and this also should be regarded as protection scope of the present invention.
