Abstract
The utility model discloses a diesel filter heating device for an integrated contact type fuel oil temperature sensor. According to the diesel filter heating device, by designing a flow deflection tube at the external part of a heating element of the heating device, the input oil can uniformly flow through the heating element through the flow deflection tube, adequately absorbs heat and is heated; and by designing a temperature-sensing element mounting groove at the outside of the flow deflection tube, the temperature-sensing element can be in direct contact with the input oil and timely sense a real temperature of the input oil, so that the problems that a switch or a heater works when not needed and cannot heat when needed due to non-uniform fuel heating caused by inadequate design before are avoided, meanwhile, the degree of accuracy of the temperature-sensing element is improved, the service lives of relevant elements are prolonged, the energy consumption of the relevant elements is lowered, and vehicles can be normally driven.
Description
Technical field
The utility model relates to automobile filter field, particularly a kind of filter heating device of integrated touch fuel temperature sensor.
Background technique
can only take split-type design to solve owing to can't solving heat responsive element with the problem of heating element phase mutual interference in the automotive preheating system that is using in the market, do like this and can significantly reduce manufacturing efficiency and raise the cost, what automobile preheater mostly all adopted in using is the mode of metal shell parcel heating element, doing like this heat that makes heating element can not be dispersed fully, and can not well can only heat its peripheral oil plant of flowing through whole input oil plant heating, and the temperature transducer of use on automobile filter, be all contactless, be that temperature sensing device and housing contacts are again by the such way of housing contacts fuel temperature sensor, can't sense timely and accurately real-time oil temperature and be subject to sheathing material, the impact of the factors such as size, and costly.
Summary of the invention
In order to overcome defects, the utility model provides the not high problem of a kind of effective solution fuel temperature sensor precision and can guarantee that the input oil plant of the overwhelming majority reaches the diesel-oil filter heating equipment of the purpose of homogeneous heating by heating element.
the utility model for the technological scheme that solves its technical problem and adopt is: a kind of diesel-oil filter heating equipment of integrated touch fuel temperature sensor, it comprises the heated seats that is tightly connected with diesel-oil filter filter block one end, the filter base the other end is provided with filler opening, filter base one side is provided with oil outlet, described heated seats relies on filter base one side and is fixedly connected with one as for the heating element in filter base, the opposite side of heated seats is equipped with fastening flange, fastening flange is provided with power input, the honeycomb duct of a sheathed tubulose on described heating element, described honeycomb duct is between heating element and filter base, and be provided with the gap for the fuel oil process between honeycomb duct and filter cleaner, described honeycomb duct one end is provided with fuel-displaced breach and is fixedly connected with heated seats, honeycomb duct the other end opening, the outside of described honeycomb duct is provided with some mounting grooves, all fixedly mount a heat responsive element in described each mounting groove, be provided with simultaneously the temperature sensing output terminal that is connected with heat responsive element on fastening flange.
As further improvement of the utility model, the fixing end of described honeycomb duct and heated seats is provided with two fuel-displaced breach, honeycomb duct surface between described two breach is provided with two mounting grooves that axially arrange side by side, and the end that each mounting groove relies on oil outlet all fixedly mounts a heat responsive element.
As further improvement of the utility model, described heating element is the rectangular strip shape body of cross section, described honeycomb duct madial wall is provided with the draw-in groove that is embedded for heating element both sides, also is provided with a locking nut in honeycomb duct, and locking nut wore heating element it is fixedly connected with honeycomb duct.
As further improvement of the utility model, be provided with a circular groove outside described heated seats, seal ring is installed in circular groove.
structural principle of the present utility model is: at the outside design of the heating element of heating equipment one honeycomb duct, the oil plant of input can be managed by refluence flow through uniformly heating element and absorb fully heat and heated, on outside honeycomb duct, design heat responsive element mounting groove can directly contact with the input oil plant heat responsive element, sense in time the temperature of real input oil plant, due to heat responsive element and heating element is gapped and wrong high temperature signal is transmitted in the spaced apart interference that makes it and can not be subject to heating element of diversed tube wall, and there are space and mounting groove can make the oil plant of the part input heat responsive element of directly flowing through without heating element flows through between honeycomb duct and fuel flow channels, again because so incoming pressure does not necessarily have greater than delivery pressure the situation that adverse current after heating or temperature transducer peripheral fuel can't flow, thereby make heat responsive element perceive the temperature of input fuel in time, correct temperature.
the beneficial effects of the utility model are: this device is owing to having cancelled the automotive preheating system split-type structural that generally uses at present, heat responsive element is integrated in heating equipment, reduced number of elements, can make the improving productivity 23% of fuel oil preheating system, the part sourcing cost descends 30%, and make the heat that the efficient of heating element is sent to input oil plant by homogeneous heating by the design that increases honeycomb duct, the time work of having avoided the not enough fuel inhomogeneous switch of heating that causes of design before this or heater not to need, the bad problem that does not heat again when needing heating, improved simultaneously the degree of accuracy of heat responsive element, reduce energy consumption the working life that has extended related elements, vehicle can normally be travelled.
