And, in perpendicular to the surface of the axis of fuel supplying device 1 (surface that promptly is parallel to pressing plate 10), Heat sink 32,32 are arranged in the circle (by the circle shown in the dot and dash line among the figure), this circle with the center of fuel supplying device as its center, and with this center to the distance of the excircle of filter housing (being fuel filter) as its radius.Therefore, can prevent that Heat sink 32,32 from increasing fuel supplying device 1 size radially, thereby can make fuel supplying device 1 compactly.
Below description is formed on the circuit housing 14 on the upper surface of pressing plate 10 and is installed in control module in the circuit housing 14.Can be clear that from Fig. 4 to Fig. 6 circuit housing 14 is formed with rectangular shape by four 15a of wall portion on the upper surface that is erected at pressing plate 10.One of them of connector 13 and four 15a of wall portion forms as one.The upper surface of circuit housing 14 opens wide.The upper end part of Heat sink 32 is arranged in the circuit housing 14.That is to say that Heat sink 32,32 passes pressing plate 10, its upper end is positioned on the pressing plate 10, and its lower end 10 times (at fuel tank 34) (seeing Fig. 5 and Fig. 6) that are positioned at pressing plate.
The upper end portion of Heat sink 32,32 is all crooked toward each other.A surface (lower surface) of the upper end portion of Heat sink 32 contacts with the upper surface of pressing plate 10.When Heat sink 32 is crooked, its upper end be adjacency and two Heat sinks 32 between have the space hardly.Holding part 15b, 15b are formed at the curved section near Heat sink 32,32.Holding part 15b, 15b keeps heat sink (heat sink) (back will be described).Condenser holding part 15c and coil holding part 15d are formed at one of them side of holding part 15b.
As shown in figure 13, control module is installed in the circuit housing 14.Control module comprises: heat sink 44, be fixed on electronic device 46 and 48, condenser 50, choking coil 52 and bus bar 56 on the heat sink 44.Heat sink 44 is formed by the metallic material with high thermal conductivity coefficient (for example aluminium, copper).The bottom surface of heat sink 44 contacts with Heat sink 32.Heat sink 44 is by holding part 15b, and 15b remains on the Heat sink 32.
The electronic device 46 and 48 that is fixed on the heat sink 44 comprises diode or power transistor (MOS transistor etc.).Described electronic device 46 and 48 forms the pump drive circuit.The direct current that the pump drive circuit is supplied with extraneous power supply is converted to pump driving power supply, and it is supplied to petrolift.
Potting material 58 is filled between circuit housing 14 and the control module.Potting material 58 prevents that moisture or dust from entering control module.Can use for example hot silicon (thermalsilicon), resin or epoxy resin in the potting material 58.And, alumina fibre (filler) can be sneaked in the described resin.Can increase the thermal conductivity of potting material 58 by increasing alumina fibre.
Be described in the order of installation and control module and Heat sink 32 in the circuit housing 14 below to Figure 13 with reference to Fig. 7.As shown in Figure 7, at first in Heat sink 32, form through hole 32a.Then, Heat sink 32 is approximate with right-angle bending at the upper end of through hole 32a.And, though through hole 32a is formed in the Heat sink 32 in the present embodiment, does not form through hole in the Heat sink and equally be fine yet.
Then, a plurality of Heat sinks 32 and connector 13 are arranged in the mould, and pressing plate 10 uses molded of resin material.Pressing plate 10 after molded is shown in Fig. 8.Can clearly be seen that from Fig. 8 the 15a of wall portion, holding part 15b, condenser holding part 15c and coil holding part 15d and the pressing plate 10 of circuit housing 14 form as one.And Heat sink 32 is inserted mode system in pressing plate 10, and resin material is inserted among the through hole 32a of Heat sink 32.Therefore Heat sink 32 can firmly be fixed in the pressing plate 10.
In above-mentioned example, molded pressing plate 10 when a plurality of Heat sinks 32 are in bent state.Yet a plurality of Heat sinks 32 can be integrally molded with pressing plate 10, then can crooked these Heat sinks 32.Under the situation of this method of employing, molded pressing plate 10 in the top and bottom of supporting Heat sink 32, thus can prevent that the pressure that produces from causing Heat sink 32 to come off from resin during molded.And Wan Qu Heat sink 32 is elevated to the top of the upper surface of pressing plate 10 owing to elastic recovery.Therefore, when heat sink 44 was arranged on the Heat sink 32, Heat sink 32 can apply heat sink 44 and upward pressure.Therefore heat sink 44 firmly keeps by holding part 15b.
After the molded pressing plate 10, control module is installed on the pressing plate 10.Fig. 9 shows the exploded view of the parts (44,46,48,50,52,56) of pressing plate 10 and control module.
In the present embodiment, electronic device 46 and 48, condenser 50 and choking coil 52 at first are fixed on the bus bar 56 and (promptly form control module 60 (this state is shown in Figure 10)).Then, heat sink 44 is fixed on the electronic device 46 of control module 60 and 48 the lower surface (this state is shown in Figure 11).Then, the control module 60 of having fixed heat sink 44 is installed in the precalculated position of pressing plate 10, and the terminal 13b of bus bar 56 and connector 13 is connected (this state is shown in Figure 12).At last, fill circuit housing 14 (this state is shown in Figure 13) with potting resin 58.Therefore, in the method, it is as a whole that the parts (44,46,48,50,52,56) of forming control module are formed, thereby control module can be installed in the pressing plate 10 effectively.
The method that control module is installed in the pressing plate 10 is not limited to above-mentioned example.For example, the parts (44,46,48,50,52,56) of composition control module can be installed in the pressing plate 10 independently.Selectively, when molded pressing plate 10, bus bar 56 can be integrally molded, and electronic device 46 and 48 etc. can be fixed on the bus bar 56 that is integrally molded.
The operation that now description is had the fuel supplying device 1 of above-mentioned structure.When being used for control signal that the order petrolift drives and being input to control module, the electronic device 46 of control module and 48 operations (promptly carrying out the switching of the switching member of power transistor for example or similar device).Therefore, the direct current of being supplied with by external power supply is converted into pumping excitation voltage, and outputs in the petrolift, and the motor in the petrolift begins rotation.
When the fuel pump motor rotated, the fuel in the fuel tank 34 passed through suction filter 26 and is inhaled in the petrolift.The pressure that sucks the fuel in the petrolift increases, and fuel is discharged by the fuel tap hole of petrolift then.Regulate from the pressure of the fuel of petrolift discharge by pressure regulator 36, fuel is along connecting tube 38 inflow filter housings 22 then.Has foreign matter in the fuel of inflow filter housing 22.These foreign matters may comprise very little material, remove these very little materials by the fuel filter that is contained in the filter housings 22 from fuel, discharge these very little materials then from fuel tap hole 42.The fuel of from fuel tap hole 42, discharging flow through discharge tube 11 and supply engine on the upper surface of pressing plate 10.
When the electronic device 46 and 48 of control module moves (when the switching member of control module is carried out switching), electronic device 46 and 48 produces heats.Be transmitted to the upper end portion of Heat sink 32 by heat sink 44 by electronic device 46 and 48 heats that produce.A plurality of lower ends of Heat sink 32 are passed pressing plate 10 and are stretched in the fuel tank 34, and these lower ends extend near the lower end of fuel supplying device 1.Therefore, the lower end of Heat sink 32 is immersed in the fuel that stores in the fuel tank 34, and the heat that is transmitted to Heat sink 32 is sent in the fuel that stores in the fuel tank 34, thus cooling electronic device 46 and 48.
And the excess fuel of the fuel of discharging from petrolift turns back to the fuel tank 34 by pressure regulator 36.Owing to discharge towards Heat sink 32 from the fuel that pressure regulator 36 turns back to the fuel tank 34,, thereby also can splash, contact cooling heat dissipation plate 32 from the fuel that pressure regulator 36 returns even the fuel quantity in the fuel tank 34 significantly reduces.Therefore effective cooling heat dissipation plate 32.
Can know clearly that from above-mentioned explanation the heat production electronic device 46 of control module and 48 is connected to the upper end of Heat sink 32 by heat sink 44, and the lower end of Heat sink 32 is immersed in the fuel in the fuel tank 34.Therefore, Heat sink 32 can contact with the fuel that stores in the fuel tank 34, and irrelevant with the flow velocity of the fuel of discharging from petrolift, and the heat of electronic device 46 and 48 can be dispersed in the interior fuel of fuel tank 34.Because the heat of control module is dispersed in the fuel in the fuel tank 34, so can suppress to supply to fuel overheated of internal-combustion engine from petrolift.Therefore, can suppress bubble and sneak in the fuel that supplies to motor, so motor can be carried out the burning with enough air fuel ratios.
And, because electronic device can use the area of Heat sink 32 to regulate the cooling capacity that is used for cooling electronic device 46 and 48, so can easily obtain required cooling capacity.And, owing to discharge and discharge towards Heat sink 32 by the excess fuel that pressure regulator 36 returns from petrolift, so even the fuel quantities that store in the fuel tank 34 significantly reduce, cooling heat dissipation plate 32 effectively still.

Under the situation of utilizing a plurality of cooling rods 64, as mentioned above, under the situation of using a plurality of cooling rods 64, compare with the volume of cooling rod 64, can make the contacted area of fuel in cooling rod 64 and the fuel tank bigger.Therefore, even heat sink is made lessly (that is, making the area that cooling rod 64 is set make lessly), still can realize enough cooling capacities.And, can make control module less.
And, with identical among the embodiment who has described, can adopt a kind of structure, in this structure, make the fuel that returns in the pressure regulator fly to cooling rod 64.And the outer circumferential side that the stem 64a of cooling rod 64 can be arranged on shell of fuel pump is not provided with the part of filter housings.
And, in the above-described embodiments, discharge towards Heat sink 32 from the fuel that pressure regulator 36 returns.Yet, can discharge towards the lower surface (position of heat sink 44 is set) of pressing plate 10 equally from the fuel that pressure regulator 36 returns.By this structure, the fuel that returns from pressure regulator 36 also can be used for cooling off effectively control module.
(second embodiment)
The fuel supplying device of the second embodiment of the present invention is described to Figure 23 below with reference to Figure 21.As shown in figure 21, second embodiment's fuel supplying device comprises the pressing plate 110 on the mounting hole that is connected to fuel tank 100.Pressing plate 110 forms by dielectric resin material is molded.Fuel discharge route 108 is formed in the pressing plate 110.Branched bottom 108a is formed at the neutral position of fuel discharge route 108.Pressure regulator (safety valve) 112 is connected to the end of branched bottom 108a.Discharge tube joint 111 is formed at the end of fuel discharge route 108.The discharge tube (not shown) is connected to discharge tube joint 111.The sparger (not shown) is connected to the other end of discharge tube, and fuel supplies to the motor from sparger.
