Definitions
- Coolant pump in particular flow-cooled electrical coolant pump with integrated directional valve, and method therefor
- the present invention relates to a coolant pump according to the preamble of claim 1 and a method therefor according to the preamble of claim 22.
- coolant pumps are increasingly being used, the speed of which can be varied and therefore the delivery rate can be regulated.
- the electric coolant pump with integrated directional valve discussed there has a coolant pump housing that has a suction nozzle for the inlet from the cooler, a bypass nozzle for the inlet from the bypass circuit and a pressure nozzle for the supply or return of the coolant to the motor vehicle engine.
- a coolant pump electric motor is arranged in the coolant pump housing and the circulated coolant flows around the motor housing. The pump motor drives a pump impeller via a pump shaft to circulate the coolant.
- Inlet and bypass nozzles are integrated upstream in front of the directional valve integrated in the coolant pump housing in the inlet to the pump, so that when the directional valve is open, a mixture of coolant coming from the cooler and heated coolant coming directly from the motor vehicle engine is sucked in by the pump impeller and past the pump motor to the downstream Pressure relief for the supply or return of this coolant mixture to the motor vehicle engine takes place.
- Coolant mixture can be exposed to an extremely high thermal load, at least temporarily.
- the suction nozzle is arranged in the region of the end of the pump motor facing away from the pump impeller. Furthermore, it is proposed for the first time that the bypass connection is arranged in an area downstream of the suction connection, in particular after the pump motor.
- the coolant pump according to the invention is also characterized by its improved robustness, an expanded range of use and significantly reduced manufacturing costs.
- the flow or coolant-cooled electric coolant pump according to the invention is an inexpensive and particularly reliable alternative in comparison to known solutions on the market.
- the coolant coming from the cooler circuit can be mixed with the coolant of the bypass circuit which can be sucked in through the bypass nozzle after the pump motor by the directional control valve.
- a bypass valve opening and reclosing opening of the bypass nozzle is arranged in an area upstream of the pump impeller, so that the coolant mixture of cooled coolant coming from the cooler and heated coolant coming from the bypass are accelerated or circulated together by the pump impeller can.
- the mouth of the directional valve lies in a region between the pump impeller and the downstream end of the flow channel.
- the plastic pump housing and the valve slide can be manufactured particularly cheaply, for example, using the plastic injection molding process. Post-processing of these components is advantageously not necessary.
- the directional control valve equipped with a valve slide offers the further advantage of a fail-safe position, so that the radiator access is open in any case if the valve fails.
- it is characterized by the lowest possible differential pressure, which ideally approaches zero. There is therefore advantageously no pressure drop at the valve slide, which ultimately leads to the fact that a very low switching power is sufficient for switching or actuating the valve.
- valve spool Another advantage of the valve spool is that it can be designed without any leakage. In contrast, leakage can never be completely ruled out in rotary slide valves due to the parts moving transversely to the main flow direction.
- the seal can be an elastomer seal, for example.
- the ring-shaped seat pad guarantees absolutely tight closing. Secondary leaks are excluded. A restriction of the distribution paths, regardless of whether the directional valve is now in the "bypass closed” position or in the "bypass open” position, is impossible even in intermediate positions. This is a special ders streamlined valve variant specified.
- a cylindrical sleeve can be sealed particularly easily in a cylindrical housing, so that secondary leaks are also excluded for this reason.
- the pump housing is constructed in two parts. This enables a simplified construction of the electric coolant pump. Their assembly is made easier.
- the electric actuating magnet has coil contacts oriented in the longitudinal direction, which, when the two housing parts are joined together, advantageously via correlating contacts with a control device accommodated in the other housing part, such as a CPU, a control unit or the like, can be brought into contact. This also makes assembly easier.
- the directional control valve or its valve slide can be driven or switched hydraulically with an expansion element.
- the expansion element is designed, for example, as a wax element, the change in volume of which, due to a change in the temperature prevailing in the coolant flowing past, leads to a change in volume in an adjacent, separate transmission medium, for example a water / glycol mixture which can also be used as a coolant ,
- This separate transmission medium is separated from the wax element, for example by a flexible membrane.
- the change in volume in the transmission medium is transmitted via corresponding lines, connecting bores or connecting channels to a cylinder chamber of the valve spool so that it can be actuated hydraulically.
- a restoring force can be applied to the valve slide with a spring or the like.
- Expansion element is made of wax. Its melting point is around 85 ° C. Its temperature-dependent change in volume can then be done via a separate
- Valve spool are transmitted.
- the expansion element formed from wax should be arranged in an area adjacent to the pressure port in the pump housing. It can adjoin the coolant flowing past with a metallic inner wall arranged radially inside the expansion element, which can be designed, for example, as a metallic cylinder jacket.
- the expansion element can be separated from the associated separate coolant with a membrane arranged radially outside of it in such a way that a temperature-dependent volume change of the expansion element can be transferred to the coolant.
- the separate coolant can in turn be moved via the connecting lines into a cylinder space of the valve slide that can be driven hydraulically therewith.
- the task is solved by the features of claim 22.
- a method for conveying coolant with a coolant pump for a coolant circuit of a motor vehicle internal combustion engine having at least one cooler circuit and a bypass circuit has the following steps: a) supplying the coolant from the cooler to the coolant pump through a suction connection of the coolant pump housing, b) supplying the coolant from the bypass circuit to the coolant pump through a bypass connection, c) returning the coolant from the coolant pump to the motor vehicle engine through a pressure port, d) circulating the coolant with a pump impeller, which is driven by a coolant pump electric motor via a pump shaft, the coolant flowing around the motor, e) adjusting the mixing ratio of the coolant flows circulating through the coolant pump with one in the coolant pump housing integrated directional valve.
- the temperature of the mixed coolant is detected in the pump housing outlet leading to the motor vehicle engine, that is to say in the area of the pressure port. This ensures that the motor vehicle engine is always supplied with a sufficient amount of coolant at the required temperature.
- the amount and temperature of the coolant flowing through the pressure port to the engine are regulated depending on the temperature and amount of the hot coolant supplied by the bypass, the coolant supplied by the cooler, the amount of heat entered by the electric motor and, if applicable, a heating return or another return, such as heated further coolant supplied by a lubricating oil heat exchanger or a cylinder block cooling circuit.
- the CPU or control unit of the pump can issue commands or voltage signals to the coil carrier and the pump motor, so that the desired or required valve position is continuously adjusted and an interrogated engine speed is recorded.
- a correspondingly miniaturized or adapted variant of the slide valve can be used to control the return flow from a heater, a transmission oil heat exchanger or the like.
- the coolant pump housing is expanded by the valve function. This increases the functionality of the coolant pump and at the same time reduces the design effort, which leads to less assembly effort and ultimately to a lower price.
- the split design of the housing also helps to reduce costs, since the division of the housing makes it easier to assemble the individual components.
- the pump impeller arranged downstream in the flow direction after the pump motor on the pump shaft has, for example, an impeller and a stator. The principle used here corresponds to the already proven principle of the axial pump, as it is successfully sold in the house of the applicant. The required, narrow running gap is machined in one setting, so that the necessary accuracy is ensured and post-processing is not necessary.
- the control of the coolant pump according to the invention is designed so that even with a closed coolant circuit, ie with an open bypass circuit, there is no risk of the electric motor overheating.
- the cooled coolant coming from the cooler is in the valve position "bypass open” and “cooler inlet closed” up to the downstream end of the pump motor housing and encloses the pump motor or its housing. This means that even in the worst case, the coolant can still absorb a temperature interval of at least 7 ° C of heat at a maximum of 113 ° C until 120 ° C is reached and components are at risk of heat death.
- the control unit of the pump ensures that this cannot happen.
- the electromagnet is opposite the valve sleeve with rod seals
- valve sleeve is spring-loaded, for example, or with alternatives
- the housing of the pump motor can be made of metal, for example aluminum or another noble metal that is particularly good heat conductor. This ensures optimal heat dissipation from the electrically operated pump motor to the coolant flowing around it.
- Fig. 2 shows a longitudinal section through an exemplary embodiment of the
- Coolant pump with the directional control valve in the "bypass closed” or “cooler inlet open” position;
- FIGS. 2 and 3 shows the coolant pump variant shown in FIGS. 2 and 3 with the valve position “inlet from cooler closed” or “bypass open”;
- FIG. 5 shows a section through the coolant pump shown in FIG. 4 along the section line B-B;
- Fig. 6 is a 3D view of the pump shown in Figs. 2 to 5;
- the electrical coolant pump 1 with an integrated directional valve shown schematically in simplified form with a symbol in FIG. 1, is further explained in detail in different variants in FIGS. 2 to 8.
- 2 shows a first exemplary embodiment of a coolant pump 1 in longitudinal section.
- the coolant pump housing 14 is divided into two in this embodiment. It consists of a first housing part 16 and a second housing part 18. Both housing parts 16 and 18 are firmly connected to each other with a ring-shaped clip, clamp or clip 20, tightly closing.
- the housing 14 can also be made in three or more parts or also in one part with a cover.
- a coolant pump electric motor 26 is arranged in the coolant pump housing 14.
- the motor housing 28 is flowed around by the coolant flowing past to cool the electric motor 26.
- the pump motor 26 drives a pump impeller 32 via a pump shaft 30.
- the pump impeller 32, the pump shaft 30 and the pump motor 26 are arranged coaxially to the longitudinal axis X of the pump housing 14.
- the coolant KZK circulated with the coolant pump 1 and coming from the cooler circuit 4 is mixed with the coolant KZB, which comes from the bypass connection 24 and comes from the bypass circuit 8, through the directional control valve 40.
- a mouth 62 of the bypass nozzle 24, which can be opened and closed again with the directional control valve 40, is arranged in the area 46 upstream of the pump impeller 32.
- the flow channel 56 delimited by the inner wall 54 of the pump housing 14 and / or by the inner wall 60 of the directional control valve 40 on the one hand and on the other hand by the outer wall 52 of the pump motor 26 is ring-shaped in a particularly preferred embodiment or has an annular cross-section. This defines a jacket flow 56 which surrounds the motor housing 28 in an annular manner and flows past the pump motor 26 and thus optimally cools it.
- the flow channel 56 has a cross section 66 that is constant in the flow direction. From the downstream end 64 of the flow channel 56 or from the downstream end 68 of the pump motor 26 to the pump impeller 32, there is a continuous or constant constriction of the diameter prevailing at the end of the flow channel 56 down to the inside diameter 70 of the pressure port 34.
- the electric actuating magnet 76 has coil contacts 96 oriented in the longitudinal direction X or parallel to the X axis. These coil contacts 96 correlate with corresponding contacts 98 of an electronic component integrated in the housing part 18, such as a control device 100, a CPU or the like, so that the control device 100 and the electric actuating magnet 76 directly during the assembly of the two housing parts 16 and 18 without further action can be brought into contact with one another.
- An amplifier unit 102 is also housed in the housing part 18. This can be connected to corresponding control loops from the outside by a plug 104.
- the required outputs are then controlled via corresponding links, for example via corresponding control loops, the control device or CPU 100 or the like.
- the links are freely programmable depending on the internal combustion engine.
- the program can then be stored, for example, in the engine electronics of the respective internal combustion engine. A separate electronics is then not necessary.
- the present invention for the first time specifies a coolant pump for a coolant circuit of a motor vehicle internal combustion engine, which has at least one cooler circuit and a bypass circuit.
- the coolant pump housing has a suction connection, a bypass connection and a pressure connection, as well as a coolant pump electric motor arranged in the coolant pump housing, the motor housing of which the coolant flows and which drives a pump impeller via a pump shaft, as well as a directional valve integrated in the coolant pump housing.
- the suction nozzle is arranged for the first time in the region of the end of the pump motor facing away from the pump impeller.
- the bypass nozzle is also arranged in an area downstream of the suction nozzle.
- the pressure port is arranged in an area downstream of the bypass port.
