Descrizione di una domanda di brevetto per modello di utilità dal titolo: "Pompa elettrica per circuiti di raffreddamento Description of a patent application for a utility model entitled: "Electric pump for cooling circuits
DESCRIZIONE DESCRIPTION
Il presente trovato si riferisce a una pompa elettrica per circuiti di raffreddamento. The present invention relates to an electric pump for cooling circuits.
Più in particolare, il presente trovato si riferisce a una pompa elettrica per circuiti di raffreddamento di motori a combustione interna di autoveicoli e simili. More particularly, the present invention relates to an electric pump for cooling circuits of internal combustion engines of motor vehicles and the like.
Come è noto, i motori a combustione interna comprendono organi di raffreddamento, quali pompe, ventilatori scambiatori e radiatori, atti a dissipare il calore che viene ceduto all'esterno attraverso il liquido refrigerante che lo ha sottratto al motore stesso percorrendo un determinato circuito. As is known, internal combustion engines comprise cooling members, such as pumps, fans, exchangers and radiators, designed to dissipate the heat that is transferred to the outside through the coolant which has removed it from the engine itself by traveling along a certain circuit.
Il dispositivo che determina tale circolazione del fluido è costituito da una pompa, tradizionalmente attivata dall'albero motore. The device that determines this circulation of the fluid is constituted by a pump, traditionally activated by the motor shaft.
Questa nota soluzione, benché sostanzialmente adeguata sotto il profilo funzionale, presenta inconvenienti di rilievo, che riguardano anzitutto la complessità costruttiva e l'assemblaggio dei diversi e numerosi componenti la pompa. This known solution, although substantially adequate from a functional point of view, has significant drawbacks, which primarily concern the constructive complexity and the assembly of the various and numerous components of the pump.
Le pompe elettriche attualmente note, richiedono la predisposizione di molteplici componenti singoli, quali ad esempio la capsula di isolamento tra statore e fluido, la semivoluta, la flangia riportata per il fissaggio della pompa al rispettivo basamento e la sede per l'alloggiamento della scheda elettronica di comando e controllo. Currently known electric pumps require the preparation of multiple single components, such as for example the isolation capsule between the stator and the fluid, the semi-volute, the flange shown for fixing the pump to the respective base and the seat for housing the electronic card. command and control.
L'allestimento e il reciproco assemblaggio di tali componenti determinano, come intuibile, difficoltà non trascurabili e conseguenti costi, che si ripercuotono in termini economici sul prodotto finito; è altrettanto evidente, inoltre, che l'assiemaggio di una pluralità di componenti, con riguardo a prodotti del tipo in questione, determina anche la necessità di provvedere altrettanti punti di tenuta, i quali costituiscono notoriamente potenziali elementi di criticità quanto a malfunzionamento e guasti. The setting up and mutual assembly of these components determine, as can be guessed, not negligible difficulties and consequent costs, which have an economic impact on the finished product; it is equally evident, moreover, that the assembly of a plurality of components, with regard to products of the type in question, also determines the need to provide as many sealing points, which are notoriously potential critical elements in terms of malfunctioning and failures.
Ulteriormente, le pompe elettriche attualmente note sono tradizionalmente provviste di un organo reggispinta dell'albero rotore, il che comporta ulteriori complicazioni sia costruttive che di montaggio. Furthermore, currently known electric pumps are traditionally provided with a thrust member of the rotor shaft, which entails further complications both in construction and in assembly.
Scopo del presente trovato è quello di ovviare agli inconvenienti sopra lamentati. The purpose of the present invention is to obviate the above-mentioned drawbacks.
Più in particolare, lo scopo del presente trovato è quello di provvedere una pompa elettrica, specialmente destinata a circuiti di raffreddamento di motori a combustione interna di autoveicoli e simili, che comprenda un numero limitato di componenti operativi, facilmente assiemabili tra loro. More particularly, the object of the present invention is to provide an electric pump, especially intended for cooling circuits of internal combustion engines of motor vehicles and the like, which comprises a limited number of operating components, which can be easily assembled together.
Ulteriore scopo del trovato è quello di provvedere una pompa elettrica come sopra definita in cui, conseguentemente, siano ridotti i punti aitici di tenuta che costituiscono possibili cause di guasti. A further object of the invention is to provide an electric pump as defined above in which, consequently, the aitic sealing points which constitute possible causes of failures are reduced.
Non ultimo scopo del trovato è quello di provvedere una pompa elettrica atta a realizzare l'ottimale scambio termico tra fluido e scheda elettronica di comando e controllo. Not least object of the invention is to provide an electric pump suitable for achieving the optimum heat exchange between fluid and electronic command and control board.
Ulteriore scopo del trovato è quello di provvedere una pompa elettrica che non comporti la necessità di un organo aggiuntivo costituente il reggispinta dell'albero del rotore. A further object of the invention is to provide an electric pump which does not involve the need for an additional member constituting the thrust bearing of the rotor shaft.
Ulteriore scopo del trovato è quello di mettere a disposizione degli utilizzatori una pompa elettrica, specie di circuiti di raffreddamento di motori a combustione interna, atta a garantire un elevato livello di resistenza e affidabilità nel tempo, tale inoltre da poter essere facilmente ed economicamente realizzata. A further object of the invention is to make available to users an electric pump, especially for cooling circuits of internal combustion engines, capable of guaranteeing a high level of resistance and reliability over time, such that it can also be easily and economically produced.
Questi e altri scopi ancora vengono raggiunti dalia pompa elettrica del presente trovato che, specialmente adatta per circuiti di raffreddamento di motori a combustione interna, comprende un rotore con relativo albero, uno statore, una girante connessa a un'estremità di detto rotore o provvista di due o più fori passanti, una scheda elettronica di comando e controllo e una carcassa o involucro di contenimento, e che si caratterizza fondamentalmente per il fatto che detta carcassa è realizzata in resine termoindurenti o materiale plastico, con costampato almeno detto statore 14. Le caratteristiche costruttive e funzionali della pompa elettrica per circuiti di raffreddamento del presente trovato potranno essere meglio comprese dalla descrizione che segue, in cui si fa riferimento alla tavola dei disegni allegati che ne rappresentano una forma di realizzazione preferita e non limitativa e in cui: These and still other objects are achieved by the electric pump of the present invention which, especially suitable for cooling circuits of internal combustion engines, comprises a rotor with relative shaft, a stator, an impeller connected to one end of said rotor or provided with two or more through holes, an electronic command and control board and a casing or containment casing, and which is basically characterized by the fact that said casing is made of thermosetting resins or plastic material, with at least said stator 14 co-molded. constructional and functional of the electric pump for cooling circuits of the present invention can be better understood from the following description, in which reference is made to the table of the attached drawings which represent a preferred and non-limiting embodiment thereof and in which:
la figura 1 rappresenta una vista schematica in sezione longitudinale della pompa elettrica per circuiti di raffreddamento del presente trovato; Figure 1 is a schematic longitudinal section view of the electric pump for cooling circuits of the present invention;
la figura 2 rappresenta una vista schematica in sezione longitudinale del rotore di detta pompa elettrica e relativo albero; Figure 2 represents a schematic view in longitudinal section of the rotor of said electric pump and relative shaft;
la figura 3 rappresenta una vista schematica di un dettaglio ingrandito di figura 2. Figure 3 is a schematic view of an enlarged detail of Figure 2.
Con riferimento iniziale alla figura 1, la pompa elettrica per circuiti di raffreddamento del presente trovato, indicata nel complesso con 10, comprende basilarmente un rotore 12 sviluppato assialmente nel corpo-pompa e ivi supportato con mezzi noti, un complementare statore 14 e un albero 16 del rotore 12 che a un'estremità è connesso a una girante 18; all'opposta estremità, una scheda elettronica 20 di comando e controllo è collegata allo statore 14. I componenti sopra indicati sono delimitati da un involucro contenitore o carcassa 22 comprendente un condotto di aspirazione 26 e uno di mandata 24 del fluido. With initial reference to Figure 1, the electric pump for cooling circuits of the present invention, indicated as a whole with 10, basically comprises a rotor 12 developed axially in the pump body and supported therein by known means, a complementary stator 14 and a shaft 16 the rotor 12 which is connected at one end to an impeller 18; at the opposite end, an electronic command and control board 20 is connected to the stator 14. The components indicated above are delimited by a container or casing 22 comprising a suction duct 26 and a delivery duct 24 for the fluid.
Secóndo il trovato, detta carcassa 22, costituita da resine termoindurenti o materiale plastico, è costampata almeno con lo statore 14; di preferènza, la carcassa 22 porta costampati sia detto statore sia un inserto sagomato 15, fungente da sede di supporto per un alberino fisso di cui si dirà in seguito. Detto inserto è vantaggiosamente costituito da un corpo cilindrico in forma di boccola, in metallo o altro idoneo materiale. According to the invention, said carcass 22, consisting of thermosetting resins or plastic material, is co-molded at least with the stator 14; preferably, the casing 22 carries both said stator and a shaped insert 15, acting as a support seat for a fixed shaft, which will be discussed later. Said insert is advantageously constituted by a cylindrical body in the form of a bushing, made of metal or other suitable material.
L'estremità posteriore di detta carcassa o involucro è chiusa da un coperchio a bicchiere 28, vincolato mediante adesivi o equivalenti mezzi all'involucro stesso; detto coperchio, dì preferenza realizzato nello stesso materiale della carcassa 22, delimita e chiude a tenuta ermetica i componenti interni al corpo pompa, compresa la scheda elettronica 20 che è disposta in adiacenza al coperchio stesso ed è vantaggiosamente connessa allo statore 14 attraverso un organo di collegamento 30 del tipo faston o equivalenti. The rear end of said casing or casing is closed by a cup-shaped lid 28, bound by adhesives or equivalent means to the casing itself; said cover, preferably made of the same material as the casing 22, delimits and hermetically closes the components inside the pump body, including the electronic board 20 which is arranged adjacent to the cover itself and is advantageously connected to the stator 14 through a connection 30 of the faston type or equivalent.
In particolare, detta scheda è disposta in una sede ribassata 20' formata in prossimità del bordo della carcassa 22 riscontrato dal coperchio 28. In particular, said card is arranged in a lowered seat 20 'formed in proximity to the edge of the casing 22 encountered by the cover 28.
La carcassa o involucro 22 integra, in corrispondenza del fronte opposto al coperchio 28, una semi-voluta 32, realizzata in solido con la carcassa medesima all'atto della sua formatura. The casing or casing 22 integrates, in correspondence with the opposite face to the lid 28, a half-volute 32, made solid with the casing itself when it is formed.
Incidentalmente, la formatura avviene attraverso un processo di stampaggio grazie ad uno stampo in acciaio, in cui, prima dell'iniezione della plastica, vengono inseriti lo statore 14 e l'inserto 15. A questo punto lo stampo si chiude ed inizia la fase di stampaggio che consiste nel pressare una pastiglia di materiale plastico preriscaldato che, per l'effetto della temperatura e della pressione, passa allo stato liquido riempiendo tutte le cavità ed avvolgendo lo statore 14 e l'inserto 15. Avvenuta la solidificazione della plastica, lo stampo si apre ed è possibile estrarre la carcassa 22 integrante statore 14 e inserto 15. Incidentally, the forming takes place through a molding process thanks to a steel mold, in which, before the injection of the plastic, the stator 14 and the insert 15 are inserted. At this point the mold closes and begins the phase of molding which consists in pressing a tablet of preheated plastic material which, due to the effect of temperature and pressure, passes to the liquid state, filling all the cavities and wrapping the stator 14 and the insert 15. Once the plastic has solidified, the mold opens and it is possible to extract the casing 22 integrating the stator 14 and insert 15.
In posizione contrapposta rispetto al coperchio 28, cioè sul fronte della semi-voluta 32, la carcassa 22 è provvista di un coperchio sagomato, indicato con 28' e realizzato in materiale termoplastico; detto coperchio 28' comprende convenzionalmente detti condotti di aspirazione 26 e di mandata 24 del fluido ed è reso solidale alla carcassa 22 mediante adesivi che garantiscono sia la resistenza meccanica che la tenuta ermetica. In an opposite position with respect to the lid 28, ie on the front of the half-volute 32, the casing 22 is provided with a shaped lid, indicated with 28 'and made of thermoplastic material; said cover 28 'conventionally comprises said fluid intake ducts 26 and delivery 24 and is made integral with the casing 22 by means of adhesives which guarantee both mechanical strength and hermetic seal.
Una flangia 34 di fissaggio della pompa 10 al rispettivo basamento (non illustrato) è vantaggiosamente ottenuta in corpo unico con la carcassa medesima durante il costampaggio. A flange 34 for fixing the pump 10 to the respective base (not shown) is advantageously obtained in a single body with the casing itself during co-molding.
Secondo un'ulteriore vantaggiosa caratteristica del trovato, l'albero 16 del rotore, rappresentato in dettaglio alla figura 2, integra assialmente il citato alberino di supporto 36 che funge da reggispinta ed è dotato di foro passante 38 longitudinalmente esteso; l'alberino fisso 36 è provvisto, a circa due terzi del proprio sviluppo, di un solidale risalto o collare anulare 40, che si impegna in una complementare sgolatura 42 formata lungo un manicotto 44 adiacente al rotore 12. According to a further advantageous characteristic of the invention, the rotor shaft 16, shown in detail in Figure 2, axially integrates the aforementioned support shaft 36 which acts as a thrust bearing and is equipped with a longitudinally extended through hole 38; the fixed shaft 36 is provided, approximately two thirds of its length, with an integral projection or annular collar 40, which engages in a complementary groove 42 formed along a sleeve 44 adjacent to the rotor 12.
Come evidenziato a figura 1 dalle frecce F, FI e F2, il fluido attraversa il foro passante dell'alberino 36 e due o più fori 46 realizzati nella girante, generando un flusso a ricircolo che investe sistematicamente la scheda elettronica 20; detta ultima è quindi inondata e opportunamente raffreddata durante il funzionamento della pompa. Lo scambio termico che si consegue in questo modo mantiene la temperatura di detta scheda a un livello ottimale, inferiore al limite ammesso per il corretto funzionamento della stessa. As shown in figure 1 by the arrows F, FI and F2, the fluid passes through the through hole of the shaft 36 and two or more holes 46 made in the impeller, generating a recirculating flow which systematically hits the electronic board 20; the latter is therefore flooded and suitably cooled during pump operation. The heat exchange that is achieved in this way keeps the temperature of said card at an optimal level, lower than the limit allowed for its correct operation.
Come si può rilevare da quanto precede, sono evidenti i vantaggi che il trovato consegue. As can be seen from the foregoing, the advantages that the invention achieves are evident.
La pompa elettrica del presente trovato, specialmente adatta per circuiti di raffreddamento di motori a combustione interna, risulta costituita da un numero ridotto di componenti, facilmente assiemabili in funzione della presenza della carcassa 22 realizzata mediante costampaggio. The electric pump of the present invention, especially suitable for cooling circuits of internal combustion engines, is made up of a reduced number of components, which can be easily assembled according to the presence of the casing 22 made by co-molding.
Sono conseguentemente ridotti in modo drastico i punti critici di tenuta, mentre il raffreddamento della scheda elettronica 20 di comando e controllo è assicurato in modo adeguato dal passaggio del fluido attraverso il foro 38 dell'alberino 36 e i fori 46 della girante. Ulteriormente vantaggiosa è la realizzazione di detto alberino 36 fungente da reggispinta grazie al collare 40 integrato nel blocco rotore 12. The critical sealing points are consequently drastically reduced, while the cooling of the electronic command and control board 20 is adequately ensured by the passage of the fluid through the hole 38 of the shaft 36 and the holes 46 of the impeller. Further advantageous is the realization of said shaft 36 acting as a thrust bearing thanks to the collar 40 integrated in the rotor block 12.
Benché il trovato sia stato sopra descritto con riferimento a una sua forma di realizzazione data a solo scopo esemplificativo e non limitativo, numerose modifiche e varianti appariranno evidenti a un tecnico alla luce della descrizione sopra riportata. Il presente trovato, pertanto, intende abbracciare tutte le modifiche e varianti che rientrano nello spirito e nell 'ambito protettivo delle rivendicazioni che seguono. Although the invention has been described above with reference to an embodiment thereof given only by way of non-limiting example, numerous modifications and variations will appear evident to a technician in the light of the above description. The present invention, therefore, intends to embrace all the modifications and variations that fall within the spirit and the protective scope of the following claims.
