Description
Technical field
The utility model belongs to the match equipment technical field of used in fuel oil system of motor-driven vehicle, relates to a kind of fuel heater of fuel filter.
Background technique
In the prior art, with thermistor heater band PTC sheet is the fuel heater of the fuel filter of heating element, with regard to its general structure, Chinese patent ZL2009201093987 is an integral structure, be immersed in the fuel oil in the center tube of the insertion fuel filter of integrity, and, the PTC sheet directly is immersed in the fuel oil together with all outer exposure formula of its respective electrode plates, make fuel oil directly contact with electricity, deficiency is, in case run into the metal impurities or the charge species that are mixed in the fuel oil---even the increase of the concentration of the bigger water of molecular polarity, just can not guarantee to avoid short circuit, promptly have unsafe factor to a certain degree: its PTC sheet is connected with electrode plate by the spring pressure compact form in addition, and deficiency is, PTC sheet unbalance stress, and easily therefore PTC sheet and electrode plate bad connection, easily take place in rhegma, influence using effect, also can strengthen cost of production; The end that covers of integral structure also is, no matter any component go wrong, it must integrity take out and the integrity replacing because of its structure is formed decision, and the aspect is because bimetallic temperature controller ZK is very near apart from the PTC sheet in addition, and its temperature control temperature can not in time reflect the variation of fuel oil true temperature.The product that also has a kind of similar above-mentioned patent, it also is integral structure, being installed between fuel filter and the corresponding car filter block of integrity is immersed in the fuel oil, its basic structure is, has integrated type plastic mounting frame, the PTC sheet of outer exposure formula is housed on it, it also is that the spring pressure compact form is connected with electrode plate, with regard to forming, structure do not have substantive difference with above-mentioned patent, just there is not bimetal temp controller ZK, therefore except that have with above-mentioned same deficiency, also do not have automatic temperature-controlled, thereby use very inconvenient, in addition, it must use the plastic material fabrication and installation frame of insulation because of its structure is formed decision, and it is not only easily bad by folder in application is installed, and at height, yielding and leakage of oil when low temperature changes greatly.Therefore, so far on the market all the time without any a kind of fuel heater by generally recognized as safe, reliably, easily and effectively and by widespread usage, for diesel car, be a very big shortcoming especially.
Summary of the invention
The technical problem that solves:
A kind of fuel heater of fuel filter is provided, being installed between fuel filter and the car filter block of integrity, can overcome the deficiencies in the prior art, the PTC sheet is not exposed together with its respective electrode plates is outer, use intermediate fuel oil directly not contact with electricity, can guarantee safety reliably, adopt whole precompressed compact form that PTC sheet and electrode plate are electrically connected, the PTC sheet is stressed evenly to be difficult for rhegma, is connected with electrode plate reliably, improves the quality of products, using effect is stable, can also save raw material, and adopt split-type structural, easily produce, convenient replacing of using installation and component.
The technological scheme that adopts:
A kind of fuel heater of fuel filter, has the metal scaffold, the heater and the power circuit of band temperature control circuit, it is characterized in that: every thermistor heater band PTC and corresponding electrode plate thereof in the heater circuit, contact conductor is called heating unit, after the in parallel and/or series connection of each heating unit rule, also being packed in the heating unit of regular distribution of external insulated enclosure, and, the electrode plate of each heating unit reliably is electrically connected with corresponding thermistor heater band PTC by whole precompressed compact form, and the external insulated enclosure of heating unit is drawn two electrode connections; Heating unit is that Circular Plate interlayer formula connects as one type, perhaps connects as one type for the annulus substrate in trough of belt road;
Being contained on the scaffold of the detachable property of heating unit, scaffold processes with metal material integral body, be with, has the ABAP Adapter of being used for lead-in wire on the cylindrical body of lower seal mouth, and hold the thread type bypass interface of the outside plug type connecting head that sealing introduces, the coaxial positioning short tube that has bracket support on the axis in the main body, its internal diameter is supporting with the connecting tube of using use in the installation, it is positioned at the equal diameters of external diameter with the center hole of cover heating unit thereon of the part on the carriage, after heating unit is sleeved on the spacer ferrule, on the carriage of seat in cylindrical body, the internal thread positioning hole that has the supporting correspondence that is used for the heating unit location on heating unit and the carriage, after heating unit is enclosed within on the spacer ferrule, be screwed into the internal thread positioning hole with clench nail, with the heating unit positioning and fixing on carriage, must guarantee, has the appropriate gap that is enough to satisfy the fuel flow needs between the external diameter of heating unit and the internal diameter of main body, the height of the plane, top of heating unit and the upper end actinal surface of spacer ferrule must not influence the last sealed mouth of main body and the sealing of car filter block is installed, the height of the lower end actinal surface of spacer ferrule must not influence the lower seal mouth of main body and being tightly connected of fuel filter, must not influence two electrode connections and the drawing by the bypass interface thereof of drawing on the heating unit;
Bimetallic temperature controller ZK in the heater circuit is serially connected in the positive pole of the outside plug type connecting head that links together with the ABAP Adapter lead-in wire, this connecting head is by the bypass sealing joint introducing of main body, two electrode connections of drawing on the heating unit are plugged on the outside plug type connecting head, and bimetallic temperature controller ZK temperature-sensitive face exposes.
Beneficial effect:
Among the present invention,, thereby avoided fuel oil directly to contact, can guarantee safety reliably with electricity because there be not outer the exposure in thermistor heater band PTC together with all externally insulated enclosure and indirect being immersed in the fuel oil of its respective electrode plates; Since with Circular Plate to pressing from both sides the electrode plate that whole precompressed compact form compresses each heating unit, make it reliably to be electrically connected with corresponding thermistor heater band PTC, electrically connect the area maximization thereby make, and it is stressed even, contact solid and reliable, and be not subjected to the influence of fuel oil environment, so the quality of product height, using effect is good and stablize; Because bimetallic temperature controller ZK is away from thermistor heater band PTC, and between the two and the scaffold three is mutual split-type structural, therefore, the temperature control temperature of bimetallic temperature controller ZK can in time reflect the variation of fuel oil true temperature, not only help temp autocontrolled, and help safety, simultaneously in the split-type structural, the scaffold of metal material generally can not damage, all the other the two when being out of order, also just change separately, especially bimetallic temperature controller ZK, unloading lower union joint can change easily, saves man-hour, saves raw material; Be particularly useful for diesel-oil vehicle, can realize using No. 0 diesel oil throughout the year, in severe winter, the temperature of the fuel oil that supplies motor is remained between 7～24 ℃, and can improve filter precision, combustion efficiency, reduce oil consumption and hazardous emission, integrity is installed between fuel filter and the car filter block, installation, very easy to use.
