Abstract
The invention discloses a thermostat comprising a main valve body and is characterized in that the main valve body comprises a first part and a second part which are shaped like a square plate and staggered vertically; the arc bottom end of the first part is fixed on the inner side wall of a pipeline of an automobile cooling system, the arc bottom end of the second part supports against the inner side wall of the pipeline; the thermostat further comprises a driving element made of memory alloy; both ends of the driving element are respectively fixed on the inner side of the pipeline and the second part; the driving element deforms when the cooling liquid in the cooling system reaches an appointed value to drive the second part to slide towards the first part. The driving element is made of the memory alloy instead of paraffin, and the opening direction of a valve is controlled by utilizing the torsion characteristic provided by the memory alloy, and the opening direction of the valve is inconsistent with the water flow direction any more, but vertical to the water flow direction, so that the pressure loss is reduced by more than 90%, and a broader space is provided to the design selection of a water pump of a user.
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 cooling capacity.
The present invention solves the problems of the technologies described above the technological scheme that is adopted: a kind of thermostat; Comprise valve body; It is characterized in that; Said valve body comprises be square tabular first portion and the second portion that staggers up and down and be provided with; The madial wall of the arcuate end of said first portion and the pipeline of automobile cooling system is fixed, and the arcuate end of said second portion and said pipeline madial wall butt also comprise the driving element of being processed by memory alloy; The two ends of said driving element are fixed with the inboard and the said second portion of said pipeline respectively, can be out of shape the said second portion of drive after the cooling liquid of said driving element in said cooling system reaches specified value and slide to said first portion.
The both sides, bottom surface of said first portion are provided with the chute that supplies said second portion to slide, make second portion relatively first portion slide reposefully.
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 second portion 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, and the twisting characteristic that utilizes memory alloy to provide comes the control valve opening direction; The opening direction of valve is no longer consistent with water (flow) direction; But vertical with water (flow) direction, can reduce crushing more than 90%, bigger space is provided for the design alternative of user's water pump.
Description of drawings
Fig. 1 is in the structural representation of closed condition for the embodiment of the invention;
Fig. 2 is in the structural representation of opening state for the embodiment of the invention.
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 comprises valve body 1 and driving element 2.Wherein, Valve body 1 comprises the first portion 11 and second portion 12 that is provided with up and down, and first portion 11 and second portion 12 all are square tabular, and end is an arc; Inboard adaptive with the pipeline 3 of automobile cooling system, the madial wall of the arcuate end of first portion 11 and pipeline 3 is fixed.Thus during original state, first portion 11 and second portion 12 stagger fully setting, the arcuate end of second portion 12 and pipeline 3 madial wall butts.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 second portion 12 are fixing, have angle between two arms.
When chilling temperature was lower than specified value, driving element 2 was in original state, the setting of staggering fully of first portion 11 and second portion 12; Sealed the passage between motor and the radiator; 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 second portion 12 with an end of second arm 22 of the fixing driving element 2 of second portion 12 thus and slide to first portion 11, make its arcuate end leave pipeline 3 madial walls and butt no longer, valve body 1 is opened; 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 order to make second portion 12 first portion's 11 slips relatively stably, can chute be set in the both sides, bottom surface of first portion 11, second portion 12 slides along chute.
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.
