Definitions
- the present invention relates to one of one speed controlled electric motor operated wet running Centrifugal pump, especially for use in heating and / or Cooling circuits with a control electronics having electronic module and with a spiral chamber surrounding pump housing is equipped.
- centrifugal pumps designed as wet rotors have been around since well known for a long time. They leave in small designs attach directly to the system to be pumped. you will be with powers from a few watts to about 100 watts from Synchronous or asynchronous motors and more recently too operated by electronically commutated DC motors. To set the speed of such electric motors or Frequency converters with power transistors are to be regulated used because of the strong waste heat of a special Need cooling. For cooling the power electronics known various principles.
- the power electronics can be exposed Place and be provided with cooling surfaces to to achieve cooling through the ambient air.
- This kind the cooling is especially with the small pumps ineffective and can only be used to a limited extent. Moreover contribute the necessary cooling surfaces to enlarge the mechanical construction.
- With wet running canned pumps it is known to be beneficial to the cooling electronics Expose the influence of the pump medium. This is the pump medium via the containment shell or via separate lines to the parts of the motor housing to which the electronics are attached is. It is known from larger size pumps that Use power electronics in a separate module and to expose this directly to the flow of the pump medium. Both Types of cooling supported by the pump medium are complex and contribute especially to small pumps at unacceptable costs at.
- pumps are known in which the Electronics on a heat sink between the motor housing and the pump housing is attached. This heat sink carries as additional component to be assembled separately also to a Increase in production costs.
- the object of the present invention is a wet-running To create a centrifugal pump that is highly reliable and a structurally simple at low manufacturing costs realizing possibility, the control electronics in sufficient cooling.
- the idea of the invention is that of medium flowed through and the spiral chamber at least partially surrounding pump housing itself is used as a heat sink.
- the pump housing is attached to one of the spiral chambers facing away from the surface with a receptacle on the the electronic module containing the control electronics in heat-conductive contact to the pump medium can be attached.
- the motor housing will now become the pump housing trained for this purpose.
- cooling is optimal in a simple and simple manner Cooling guaranteed so that the maximum allowable Temperature of the components is not exceeded and this be spared accordingly. This leads to an increase in Pump life. It is also advantageous that with the cooling of the invention a safe operation of the pump even at high outside temperatures, such as in Motor vehicles occur, is possible.
- Cooling no further components are required. Because of the few components is high operational reliability and Maintenance friendliness of the pump according to the invention given.
- the pump can be compact, especially in the axial direction be built and takes place even with limited spatial Conditions sufficient installation space.
- the cooling according to the invention, the axial design of the pump and thus merging in one direction, resulting in one contributes to a further reduction in assembly costs.
- the pump housing is made in one piece from metal is shaped and provided with the receptacle according to the invention.
- the pump housing forms the one that receives the impeller Impeller chamber or the spiral chamber, so that none possibly obstructive heat transfers between two Components are available. So that is the full flow of the medium used for immediate heat dissipation.
- in one piece Pump housing with a box-shaped receptacle in particular molded rectangular receiving space in which the Electronic module can be used via an opening. To this In this way, the module is completely surrounded by cooled walls.
- the electronics module itself is advantageously included a base, in particular by means of heat-conducting Paste, on one of the walls of the rectangular recording room created.
- the pump has a base plate, which is drawn in one piece from metal, in particular from sheet metal, or is die-cast and is designed as a chassis, which serves as a carrier for the other components and by means of which the pump can be held.
- This base plate serves as the rear wall of the pump housing, which is acted upon directly by the medium.
- the base plate is designed as a receptacle for the electronic module. This is advantageously in the electrical "side of the base plate, a flat mounting surface is incorporated on which the electronic module can be placed.
- the cooling according to the invention can be particularly advantageous use in pumps that are electronically commutated DC motor operated.
- the electronic one Commutation necessary electronics modules have a large Number of power semiconductors and therefore require one particularly effective cooling.
- FIG 1 is one of a speed controlled Electric motor operated and trained as a wet runner Centrifugal pump especially for use in stimulus and / or Cooling circuits shown, the impeller 1 on a shaft 2 held with pressed permanent magnet rotor 3 is.
- the centrifugal pump has a one-piece made of metal molded pump housing 4 with a central inlet 5, which is the impeller 1 rotating in an impeller chamber surrounds and forms a spiral chamber 6.
- an electronic module 7 is provided in which the power semiconductors are housed.
- the pump housing 6 has a receptacle 8 rectangular recording space in which the electronic module 7 housed and thermally conductive with the surrounding walls 9 connected is.
- the electronic module 7 can be connected via a Opening 10 are installed.
- the electrical contact between the stator windings 11 and the electronics module 7 happens via a connecting channel 12 between the Recording space and the interior of the engine housing 19. Die electrical contacting of the electronics module 7 to the external Power supply ensures a connector 13, the on the side of the receptacle 9 facing away from the impeller 1 is appropriate.
- the pump shown is a Wet rotor pump, in which the rotor 3 from the stator 14 by a Can 15 are separated.
- the containment shell 15 is on the integrally formed on a bearing bracket 16 receiving bearing plate 17.
- the bearing bracket carries one of two bushings 18 in which wave 2 is running.
- the other bearing bush 18 is in one Forming the containment shell 15 pressed.
- a Ring seal 19 used to seal the Pump housing 4 opposite the end shield 17 is a Ring seal 19 used.
- the centrifugal pump shown in FIG. 2 has a one-piece metal base plate 20, which is formed from metal, in particular drawn or die-cast, on its hydraulic "side carries a plastic housing shell 21 covering the impeller chamber.
- the housing shell 21 placed on the base plate 20 is sealed by a sealing ring 22.
- the housing shell 21 has a central suction nozzle 5 and a pressure nozzle (not shown). In the spiral space there is an improvement an element 23 of the hydraulic properties.
- the base plate 20 faces the one facing away from the impeller 1 electrical "side a pot-shaped holder 24 for inserting the stator 29.
- an electronic module 25 is placed in thermal contact on a mounting surface 26 of the base plate 20.
- the electronic module 25 is contacted via a connector 27 on the hydraulic side of the base plate 20 is attached.
- the containment shell 15 is attached to the base plate 20 molded sleeve 28 held by means of a sealing ring and is jammed by a bearing bracket 30.
- a plastic housing cover 31 put on, all on the electrical side of the Base plate 20 covers arranged components.
