Specific implementation mode
The technical solution that the invention will now be described in detail with reference to the accompanying drawings：
Such as Fig. 1, a kind of vehicle oil way heating device, including metal connecting piece, heating component 1 and installation connecting element；
The metal connecting piece is three way type structure：First connecting pin is used to connect the oil pipe of vehicle, and second connection end is for connectingThe engine picked up, third connecting pin are used for through the installation connecting element installation heating component 1.
The heating component 1 is flexible barcode, in the oil pipe that the metal connecting piece stretches into vehicle；
The heating component 1 includes as the first temperature section of high-temperature heating section and as the second temperature of low-temperature heat sectionSection, the unit length calorific value of first temperature section are higher than the unit length calorific value of second temperature section；First temperatureSection is placed in metal connecting piece, since metal connecting piece can bear higher temperature, and position be fluid mustThrough road, therefore the fluid for flowing to engine can be made to be rapidly heated, the second temperature section is adding for being placed in oil pipePlastic tubing aging is prevented while hot.
Such as Fig. 2 and 3, the heating component 1 includes being connected with each other to constitute the heater wire 1-3 and return line 1- of power circuit4.Heating component 1 at least has there are two types of arrangement：
Mode one：If Fig. 2, the heater wire 1-3 are coiled on the outside of return line 1-4, the coiling density of first temperature section is highIn the coiling density of second temperature section, to realize different sections of different heating temperature.When it is implemented, can also be according to oil circuit knotMultiple temperature sections are arranged in structure.
Mode two：As Fig. 3, the heater wire 1-3 and return line 1-4 move towards arrangement and heater wire 1-3 along heating component 1To be segmented round-trip arrangement, the round-trip density of first temperature section is higher than the round-trip density of second temperature section, to realize different sectionsDifferent heating temperature.
Further, the heating component 1 further includes being arranged between the heater wire 1-3 and return line 1-4 and wrappingThe insulating layer 1-2 on the outside of power circuit is overlayed on, short circuit is avoided.
The heating component 1 further includes being coated on outermost protective layer 1-1, prevents fluid from corroding heater strip.
Such as Fig. 1, the installation connecting element includes connection terminal 4, connecting cylinder 2, nut 3 and sealing ring 5；
The connection terminal 4 is sleeved on the root of heating component 1, includes sealing device, is connected and uses with the heating component 1It is drawn out on the outside of the right of connection terminal 4 by the connection terminal 4 in the conducting wire 6 powered for heating component 1, is connected with power supplyIt connects.
The connecting cylinder 2 is sleeved on the left end of connection terminal 4, and 2 endoporus right end of the connecting cylinder is equipped with the first guide part, instituteStating to be equipped on the outside of connection terminal 4 can limit with matched second guide part of the first guide part, the mutually matched guide partThe extreme position that connecting cylinder 2 moves right relative to connection terminal 4 can also limit connecting cylinder 2 relative to connection terminal 4 in circleAngle in circumferential direction；
2 left end of the connecting cylinder is equipped with matched first external screw thread in third connecting pin with the metal connecting piece, and right end is setThere is the second external screw thread being connected with the nut 3；
The nut 3 is sleeved on the right end of connection terminal 4, and 3 left end of the nut is equipped with counterbore；5 company of being sleeved on of the sealing ringThe right end of connecting terminal 4, side is in contact with second guide part, the other side is in contact with the counterbore of nut 3, realizes connecting pinThe sealing in 4 outside of son.
In the present embodiment, first guide part is Hexagon hole, and second guide part is outer-hexagonal.Guide part also may be usedBy be rectangular or other structures in the form of.Hexagonal advantage is：Processing technology is ripe, and the area being in contact with sealing ring 5It is larger.
When installation, the installation of metal connecting piece is completed first, and then connecting cylinder 2 is mounted on metal connecting piece, then pacifiesHeating component 1 and 4 department of assembly of connection terminal are filled, sealing ring 5 and nut 3 are finally installed.When tightening nuts 3, due to connection terminal 4It is fixed in a circumferential direction by Hexagon hole, therefore therefore heating component 1 will not rotate.
In use, being powered by conducting wire 6, the first temperature section adds the fluid that will flow into engine by metal connecting pieceHeat, second temperature section carry out low-temperature heat to oil pipe, to realize the whole heating of oil circuit, it is thus also avoided that tubing section it is oldChange.
