Description
Technical field
The invention belongs to the match equipment technical field of used in fuel oil system of motor-driven vehicle, relate to a kind of heating equipment in fuel filter of diesel vehicle.
Background technique
in prior art, fuel heater in take thermistor heater band PTC as the fuel filter of heating element has two kinds with regard to its general structure, the first is technological scheme as disclosed in Chinese patent ZL2009201093987, be immersed in fuel oil in the center tube of the insertion fuel filter of integrity, have advantages of outstanding, deficiency is, the PTC sheet is together with equal directly being immersed in fuel oil of outer exposure formula of its corresponding electrode plate, in case run into the metal impurities or the charge species that are mixed in fuel oil---the increase of the concentration of the water that even molecular polarity is larger, just can not guarantee to avoid short circuit, therefore there is unsafe factor, secondly, the PTC sheet is connected with electrode plate by spring compression type, make PTC sheet unbalance stress, easy rhegma, thereby PTC sheet and electrode plate bad connection easily occur, affect using effect, again, because bimetallic temperature controller ZK is very near apart from the PTC sheet, its temperature control temperature is difficult to the variation of reflection fuel oil normal temperature promptly and accurately, in addition, the stationary positioned of itself and car filter block, in the fuel pipe inlet that relies on after the outer account formula of petal type power interface of its circular pipe type body upper end is inserted filtration on the car filter block, this kind structure location is unreliable, whole displacement easily occurs in heater, produce axial rotation and axial float, simultaneously the ABAP Adapter lead-in wire easily and the position of the intersecting line at the inner port place of the fuel pipe inlet after the filtration on the car filter block mutually rub and cause breakage, not only affect the normal operation of fuel heater, and there is a potential safety hazard, also have, because its integral structure determines, and the circular pipe type body is that plastic is made, therefore, circular pipe type body no matter, PTC sheet or the arbitrary parts of bimetallic temperature controller ZK go wrong, must integrity take out and the integrity replacing, the second is technological scheme as disclosed in Chinese patent ZL2010205160945, overcome the deficiency that the first technological scheme exists, after in parallel and/or series connection to each heating unit rule of PTC sheet, also being packed in heating unit of regular distribution of External Insulation, realize reliable the electric connection with whole precompressed compact form again, and bimetallic temperature controller ZK and heating unit are split type, has original advantage, its deficiency is, heating unit must detachable property be contained on the metal scaffold, with regard to its overall structure, complicated structure, cost is high, and must hold in the palm being installed between fuel filter and car filter block of the connecting tube integrity takeed on by band when use installing, this just must strengthen the spatial position that fuel filter occupies, therefore for former car design, has certain narrow limitation in application.in addition in the disclosed technological scheme of Chinese patent ZL2010205160771, to the fuel heater take thermistor heater band PTC sheet as heating element, adopt the metal tub agent structure, related and/or the series connection of each heating unit rule of PTC sheet, and after External Insulation is processed, in the interlayer that is seated in cylindrical shell of regular distribution, then, again with whole precompressed compact form with in the interlayer of each heating unit stationary positioned in the metal tub main body, complete reliable electric connection, therefore this technological scheme can overcome the deficiency that in the first technological scheme, each heating unit of PTC sheet exists, can overcome again the second technological scheme and use the deficiency that exists when installing, and be convenient to process, cost is low, reliable in quality.
Summary of the invention
The technical problem that solves:
prior art is improved, with Chinese patent ZL2009201093987, ZL2010205160945 and ZL2010205160771 mutually combine, a kind of heating equipment in fuel filter of diesel vehicle is provided, can overcome the deficiencies in the prior art, each heating unit of thermistor heater band PTC reliably is electrically connected, and indirectly being immersed in fuel oil of External Insulation sealing, the heater of bimetallic temperature controller ZK and in-built PTC sheet heating unit is split type, convenient and reliable and safe being positioned on the car filter block of heater energy, and insert in the center tube of fuel filter, do not change and do not affect former car design yet, simple in structure, easily make, cost is low, easy to loading and unloading, using effect is steady in a long-term.
The technological scheme that adopts:
a kind of heating equipment in fuel filter of diesel vehicle, long cartridge type heater with and in-built heater circuit take thermistor heater band PTC as heating element supporting with the center tube of fuel filter, also have supporting Split warm control circuit and temperature control parts with bimetallic temperature controller ZK control, it is characterized in that: on the top interface of heater, the insulated enclosure formula is fixed with the mushroom-head hanging head, its center hole is drawn two electrode connections, separately have with the car filter block on filtration after fuel pipe inlet be complementary and with the suspension member of position structure, its lower end has the petal-shaped dop of reverse buckling type, in the petal-shaped dop of the mushroom-head hanging head supporting embedding of detachable property, thereby heater is located, also have the retaining spring supporting with suspension member.
Beneficial effect:
in the present invention, because the thermistor heater band PTC heating unit that is equipped with in heater is realized reliable the electric connection with whole precompressed compact form, and indirectly being immersed in fuel oil of External Insulation sealing, electrode plate G and PTC sheet are electrically connected area and maximize, and stressed even, contact solid and reliable, and be not subjected to the impact of fuel oil environment, therefore quality of product is high, safe and reliable, using effect is well also steady in a long-term, because the bimetallic temperature controller ZK in temperature control circuit and heater are split type, and be positioned at the outlet port of the fuel oil after filtration, therefore bimetallic temperature controller ZK can promptly and accurately reflect the variation of fuel oil normal temperature, simultaneously by the suspension member with position structure, heater can not only auxiliary type be positioned at the center tube of fuel filter, and can be fixed on the car filter block safe and reliable location, and need not to change and also do not affect former car design, and due to the effect of the extension of suspension member shoulder, corresponding two contact conductors also are difficult for being worn, therefore, margin of safety is high, simple in structure, easily to make, cost is low, and it is convenient to load and unload, change, and using effect is steady in a long-term.
