Abstract
In a filtering element disposed in a filter housing (12) and a filtering apparatus (10) of a heating device (34) used for heating medium flowing through the filter housing (12), a joint (40) for electrically contacting with the heating device (34) is disposed. A temperature sensor (46) is integrated in the joint.
Description
Technical field
The present invention relates to filter, liquid filter particularly, for example urea filter or fuel filter are useful on heater to the dielectric heating of the filter housings of flowing through with being arranged on filter element in filter housings and band.
Background technology
Filter usually needs in low operating temperature situation for the heater to the fluid heating of flowing through, and this is because the viscosity of medium to be filtered increases under low temperature condition and after this makes medium pass respective filter elements and becomes difficult therein.For example in diesel fuel filter, when engine cold-start, if external temperature may have problems lower than so-called fuel C FPP (cold filter plugging point).In the situation that the urea filter, heater may be necessary.
Applied heater is configured to electric PTC (positive temperature coefficient) heater herein, and it has automatic regulation function and specifically adapts with the heating state that will produce.But the PTC element is relatively costly in purchasing and processing.
In some application of filter, the assembly space of these filters is strictly limited.Use for these, in the fuel filter that comprises the filter housings with housing cup and case lid, known heater is configured in case lid, perhaps be configured to stretch into the heating rod in filter feed side (Rohseite).But two kinds of solutions relatively take a lot of trouble and need match with member extraly.
German patent document DE102007005771A discloses a kind of filter with filter element, and this filter element is arranged in filter housings, and filter is also with the heater that is useful on to the dielectric heating of the filter of flowing through.Described heater is furnished with at least one heating track, this heating track by can be for example in the heating track housing metal stamping grid of injection moulding form.
Summary of the invention
According to the present invention, a kind of filter with filter element is provided, this filter element is arranged in filter housings and is provided with for the heater to the dielectric heating of the filter housings of flowing through, in this filter, be provided with the joint that electrically contacts for heater, temperature sensor is integrated in this joint simultaneously.
The temperature sensor that so is integrated provides those information that need in order desirably to control heater about the temperature of medium in filter element.Temperature sensor is configured in joint in other words in the construction unit of joint component at this, thereby makes the unit that only has such electricity to be placed on filter.Joint preferably constitutes the grafting joint with a plurality of grafting pins.
Preferably temperature control equipment is integrated in joint in addition.Utilize this integrated frame mode can abandon the external temperature control equipment that separates in other words.Temperature control equipment can advantageously be realized by means of PTC element, PPTC element, permanent control device or temperature detect switch (TDS).
Alternatively or addedly preferably overtemperature protection system is integrated in joint.The additional integrated of this overtemperature protection system will be combined in joint for all main controls and the regulatory function of heater, provides unit a kind of compactness, that production prices are cheap and that easily respond thereby make aspect regulation technology.
At last, also special in the application of this class foundation filter of the present invention as the fuel filter on motor vehicle according to solution of the present invention.
Description of drawings
Hereinafter will further illustrate by means of the schematic diagram of enclosing the embodiment of foundation solution of the present invention.Wherein:
Fig. 1 illustrate according to of the present invention, with the stereogram of opening of the embodiment of the filter of affiliated joint;
Fig. 2 illustrates the top perspective view of opening according to the joint of Fig. 1;
Fig. 3 illustrates the perspective bottom view of opening according to the joint of Fig. 1.
The specific embodiment
Fig. 1 illustrates filter 10, and it is configured with filter housings 12.Filter housings 12 comprise with the housing cup 14 of shell face 15 and case lid 16 and about Fig. 1 below be screwed in housing on housing cup 14 at the bottom of 17.On filter housings 12, introduce in the middle of roughly in the axial direction on its shell face 15 radial finger to, be used for as the import 18 of the fuel of medium to be filtered and draw on its case lid 16 a same radial finger to outlet 20.
Be useful on the cup-shaped heating track housing 22 of another the unshowned open tubular column bodily form filter element that holds filter 10 in filter housings 12.On this heating track housing 22, heating track 34 as the heater waveform be arranged between upper end side fringe region 24 and lower end side fringe region 26.Heating track 34 causes the upper surface of heating track housing 22 always and contacts with overtemperature protection system 35 at this place.
At upper edge region 24 places of heating track housing 22, in its outside, the electric connection 40 that is arranged on filter housings 12 is arranged.
Be provided with two nipple pins 36 and 38 that axially point on the end face of heating track housing 22, be used for the contact of heating track 34.
The buttonhole 45 that described conductor rails 44 by means of being shaped on their end is connected with being connected to conduct electricity with nipple pin 36.
In addition, the temperature sensor 46 that is arranged on filter housings 12 inside is connected to below these conductor rails 44 in conductor rails 44 two conductively about Fig. 2 and Fig. 3.Therefore temperature sensor 46 is positioned at upper ora terminalis edge area 24 places of heating track housing 22 equally, but in its outside.
Be integrated with (unshowned) temperature control equipment in this external joint 40.Joint 40 constitutes the integrated morphology unit that couples on heating track housing 22 together with grafting pin 42, conductor rails 44 and temperature sensor 46 and temperature control equipment.In unshowned embodiment, also overtemperature protection system 35 is integrated in this construction unit.
Control for temperature, be integrated in the temperature that temperature sensor 46 on joint 40 is measured in filter housings 12 fuel in heating track housing 22 in other words.Therefore temperature control equipment can control time per unit through the flow of heating track 34 guiding, and then controls the heating power of the heater that therefore forms.Simultaneously, this temperature control equipment guarantees that together with overtemperature protection system 35 heating track housing 22 is not by superheated.
Claims (4)
1. filter (10) is useful on heater (34) to the dielectric heating of the described filter housings (12) of flowing through with being arranged on filter element in filter housings (12) and band,
