Description
(1) technical field
The utility model relates to a kind of diesel-oil filter, particularly a kind of diesel-oil filter heating equipment.
(2) background technique
At present, what gross mass all adopted greater than 3.5 tons automobile 90% in the world wide is diesel engine, and the car of EU member country new production in 2004 48.2% has adopted diesel engine.
The diesel engine car ratio of BMW has reached 60%, and the benz new model is also in the ratio that improves diesel engine gradually.Under the identical prerequisite of discharge capacity, the fuel consumption per hundred kilometers of diesel-oil vehicle is than gasoline car low 1/3.A nearest investigation shows, existing 73% crowd is with the factor of fuel-economizing overriding concern when purchasing car.From global range, diesel-oil vehicle has become the trend of automobile industry development.According to expectation, the five-year, China's automobile market will sweep fierce diesel-oil vehicle wind, and the market ratio of diesel-oil vehicle also will further improve, and become a kind of development trend.
Diesel vehicle winter driving or long-distance running are in the time of extremely frigid zones; analyse cured condensing at low temperatures easily because of employed fuel diesel, be subjected to factor affecting such as geographical conditions, ambient temperature phenomenons such as oil circuit stops up, fuel consume is big to occur and cause situations such as vehicle lay-off, starting difficulty to take place through regular meeting.
(3) summary of the invention
The utility model provides a kind of diesel-oil filter heating equipment that makes diesel vehicle fuel path proper functioning in winter in order to remedy the deficiencies in the prior art.
The utility model is achieved by the following technical solution:
A kind of diesel-oil filter heating equipment, comprise that one is positioned at the heating equipment at oil purifier top, this heating equipment comprises fuel oil temperature control unit, heater band, ambroin cavity, its special way is: the bottom of described ambroin cavity is placed with the conduction heat dissipation metal plate B that a slice connects the positive source joint, and conduction heat dissipation metal plate B top is followed successively by heater band, connects the conduction heat dissipation metal plate A of power cathode joint.
Diesel-oil filter heating equipment of the present utility model, described heater band are the PTC thermistor.Described PTC thermistor is a 3-4 piece positive temperature coefficient thermal sensitive ceramic resistance.
The position is laid a pressure spring respectively directly over the described heater band.Described pressure spring top is provided with a loam cake that can be fixed as one with the ambroin cavity.
For satisfying the normal usage requirement in winter of diesel vehicle fuel path, the applicant was through research and the test in nearly 1 year, finally successfully invented diesel vehicle oil supply system heating equipment, this installs main core technology is to utilize heater element PTC thermistor energy balance principles.PTC is the abbreviation of Positive Temperature Coefficient, and the meaning is positive temperature coefficient, very big semi-conducting material or the components and parts of general reference positive temperature coefficient.Usually we PTC that mentions is meant positive temperature coefficient thermistor, is called for short the PTC thermistor.The PTC thermistor is the semiconductor resistor that a kind of typical case has temperature sensitivity, and when surpassing certain temperature (Curie temperature), its resistance value is along with the rising of temperature is increasing of step evolution.
Stupalith is usually as high-resistance superior isolation body, and ceramic PTC thermistor is to be base with the barium titanate, other the polycrystalline ceramic manufacturing of mixing, have lower resistance and semiconduting properties.Reach as the some array element of crystal by the higher material of a kind of chemical valence of autotelic doping: the part of barium ions or titanate ion is substituted by the ion of higher price in lattice, thereby has obtained the free electron that some produces electric conductivity.For PTC thermistor effect, the reason that increases of resistance value step just, be that material structure is to be made of many little crystallites, on the interface of crystal grain, be that the formation potential barrier is gone up in so-called grain boundary (crystal boundary), hinder electronics and cross in the adjacent area, therefore produce high resistance.This effect is cancelled when temperature is low: hindered the formation of potential barrier and electronics can freely be flowed during at low temperature in permittivity high on the crystal boundary and spontaneous polarization intensity.And this effect is when high temperature, and permittivity and polarization intensity reduce significantly, cause potential barrier and resistance to increase significantly, present strong PTC effect.Promptly when voltage one timing electric current passes through PTC resistance at a certain temperature, because resistance is very little, by formula I=U/R and P=U
2/ R can produce bigger electric current as can be known this moment, thereby send certain heat, when the temperature of PTC thermistor reaches one regularly, very little temperature variation will cause the first mate of prevention to improve, make the PTC thermistor reach HR high resistance, the increase of impedance has just limited passing through of electric current.Cause the PTC thermistor to return to very low current and almost athermic state.When ambient temperature was reduced to uniform temperature once more, the resistance of PTC thermistor can obviously diminish again, produced certain heat simultaneously again, and above-mentioned phenomenon permanent loops replaces, and this thermistor has the flames of anger, heats characteristics such as fast.The applicant adds a sleeving temperature sensor control with the PTC thermistor just the temperature of PTC thermistor to be controlled within certain scope in addition.Finally just finished this scientific and technological invention of diesel car oil supply system pre-heating arrangement through a series of actual tests again.
After native system is installed and used in evidence, diesel engine reduces the quality requirement of diesel oil, improve one or two label, when once testing, the diesel vehicle that this pre-heating arrangement has been installed uses 0# diesel oil still can to travel by normal starting under subzero-17 ℃ of degree weather conditionss of ambient temperature, and is functional.
The utility model utilizes the electric energy of automobile current generator and storage battery, be arranged in when connecting vehicle ignition switch that diesel oil is thick, the PTC resistance of fine filtrator heats rapidly, diesel oil is heated back viscosity and density reduces, damping mobile and filter paper of filter diminishes, and just satisfies the requirement to fuel oil supply system of motor better.And the foreign material in the diesel oil are easy to separate in filter cleaner with water, thereby make the diesel oil of the diesel spray mechanical system that infeeds purer, prolong ejecting system working life, reduce consuming and loss, better save fuel cost.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing is a structural representation of the present utility model.
