Con riferimento alle annesse figure, con 1 è globalmente indicato un condensatore per un frigorifero, un congelatore, loro combinazioni e simili . With reference to the attached figures, the reference numeral 1 globally indicates a condenser for a refrigerator, a freezer, combinations thereof and the like.
Nell'esempio, il condensatore 1 è fissato a staffe 2 portate da un frigorifero domestico 3 in corrispondenza di una sua parete posteriore 4. In the example, the condenser 1 is fixed to brackets 2 carried by a domestic refrigerator 3 at one of its rear walls 4.
Il condensatore 1 comprende una serpentina 5, per un fluido refrigerante, ed un involucro 6, per una sostanza ad elevata capacità termica. The condenser 1 comprises a coil 5, for a refrigerant fluid, and a casing 6, for a substance with a high thermal capacity.
Vantaggiosamente la sostanza ad elevata capacità termica è un fluido e preferibilmente è acqua. Advantageously, the substance with a high heat capacity is a fluid and preferably it is water.
L'involucro 6 comprende tre porzioni, e precisamente una prima porzione 7, tubolare, avente una estremità superiore 7a, aperta, e una estremità inferiore 7b, aperta, nonché restanti porzioni, e precisamente una seconda porzione 8, piastriforme, avente una estremità superiore 8a e una estremità inferiore 8b, ed infine una terza porzione 9, piastriforme, avente una estremità superiore 9a e una estremità inferiore 9b. The casing 6 comprises three portions, namely a first tubular portion 7, having an open upper end 7a, and an open lower end 7b, as well as remaining portions, namely a second plate-like portion 8, having an upper end 8a and a lower end 8b, and finally a third portion 9, plate-like, having an upper end 9a and a lower end 9b.
Le porzioni 7, 8 e 9 sono tra loro affiancate e più precisamente la porzione 7 si trova posta in posizione compresa tra le due porzioni piastriformi 8 e 9, in posizione intermedia ad esse. The portions 7, 8 and 9 are placed side by side and more precisely the portion 7 is located in a position between the two plate-like portions 8 and 9, in an intermediate position thereto.
Le porzioni piastriformi 8 e 9 sono tra loro specularmente uguali o hanno giacitura complanare. The plate-like portions 8 and 9 are specularly equal to each other or have a coplanar arrangement.
Le estremità superiori 7a, 8a e 9a delle porzioni 7, 8 e 9, costituiscono nel loro complesso un collettore superiore 10, attraverso il quale dette porzioni sono tra loro in comunicazione di fluido. The upper ends 7a, 8a and 9a of the portions 7, 8 and 9, as a whole constitute an upper manifold 10, through which said portions are in fluid communication with each other.
Analogamente le estremità inferiori 7b, 8b e 9b delle porzioni 7, 8 e 9 costituiscono a loro volta un collettore inferiore 11, attraverso il quale dette porzioni sono tra loro in comunicazione di fluido. Similarly, the lower ends 7b, 8b and 9b of the portions 7, 8 and 9 in turn constitute a lower manifold 11, through which said portions are in fluid communication with each other.
E' da notare che la porzione tubolare 7, avente asse verticale X-X, ha un diametro interno D prefissato, ad esempio compreso tra 40 mm e 60 mm e che vale nell'esempio 50 mm. It should be noted that the tubular portion 7, having a vertical axis X-X, has a predetermined internal diameter D, for example between 40 mm and 60 mm and which in the example is 50 mm.
La serpentina 5, costituita ad esempio da un tubo in rame, è avvolta ad elica cilindrica, con un diametro esterno d, di poco inferiore al diametro interno D della porzione tubolare, e termina con contrapposti terminali 5a e 5b estesi assialmente e fuoriuscenti dall'involucro 6, attraverso tappi 12a e 12b posti a chiusura delle estremità aperte 7a e 7b della porzione tubolare 7. The coil 5, consisting for example of a copper tube, is wound in a cylindrical helix, with an external diameter d, slightly less than the internal diameter D of the tubular portion, and ends with opposite terminals 5a and 5b extending axially and protruding from the casing 6, through caps 12a and 12b placed to close the open ends 7a and 7b of the tubular portion 7.
E' importante notare che le porzioni 7, 8 e 9 dell'involucro 6 costituiscono un elemento in plastica 13, ottenuto per soffiaggio in un unico pezzo, secondo tecniche di per sè note, ad esempio secondo le tecniche della fabbricazione di contenitori in plastica, ad esempio contenitori in polietilene, polipropilene e simili. It is important to note that the portions 7, 8 and 9 of the casing 6 constitute a plastic element 13, obtained by blowing in a single piece, according to techniques known per se, for example according to the techniques of manufacturing plastic containers, for example containers made of polyethylene, polypropylene and the like.
Vantaggiosamente l'elemento in plastica 13 che costituisce l'involucro 6 comprende contrapposte pareti laterali 14 e 15, la parete 14 essendo rivolta verso la parete posteriore 4 del frigorifero 3 e la parete 15 essendo rivolta verso l'esterno, ad esempio a ridosso di un muro al quale il frigorifero è destinato a essere addossato. Advantageously, the plastic element 13 which constitutes the casing 6 comprises opposing side walls 14 and 15, the wall 14 facing towards the rear wall 4 of the refrigerator 3 and the wall 15 facing outwards, for example close to a wall against which the refrigerator is intended to be placed against.
Le pareti 14 e 15 presentano rispettive zone 16 e 17 (nonché 18 e 19) estese verticalmente, limitatamente a una prevalente zona centrale dell'altezza, e depresse fino a combaciare, così da delimitare la porzione tubolare 7 dalle porzioni piastriformi 8 (nonché dalla porzione piastriforme 9)-Ancora, la parete 14 presenta quattro zone troncoconiche sporgenti 20, e la parete 15 presenta quattro zone troncoconiche depresse 21, depresse fino a combaciare con le zone 20. Le zone 20 e le zone 21 formano nel complesso rispettive poppette 22, per il fissaggio, ad esempio tramite viti, del condensatore 1 alle staffe 2. The walls 14 and 15 have respective zones 16 and 17 (as well as 18 and 19) extended vertically, limited to a prevalent central zone of the height, and depressed until they fit together, so as to delimit the tubular portion 7 from the plate-like portions 8 (as well as from the plate-like portion 9) - Again, the wall 14 has four protruding truncated cone areas 20, and the wall 15 has four depressed truncated cone areas 21, depressed until they match up with the areas 20. The areas 20 and the areas 21 together form respective poppette 22 , for fastening, for example by means of screws, the condenser 1 to the brackets 2.
Ancora, le pareti 14 e 15 presentano in corrispondenza delle porzioni 8 e 9 rispettive corrugazioni , tutte indicate con 23, in forma di scanalature 24 estese verticalmente, parallele tra loro, a sezione all'incirca triangolare, con formazione di una zona 25 ad elevato scambio termico. Furthermore, the walls 14 and 15 have at the portions 8 and 9 respective corrugations, all indicated with 23, in the form of grooves 24 extending vertically, parallel to each other, with an approximately triangular section, with the formation of an area 25 with high heat exchange.
Ancora, le porzioni piastriformi 8 e 9 sono rastremate dall'alto verso il basso, ossia le pareti 14 e 15, in corrispondenza delle porzioni piastriformi 8 e 9, sono inclinate leggermente rispetto alla verticale, con riduzione dello spessore delle porzioni piastriformi dall'alto verso il basso. Again, the plate-like portions 8 and 9 are tapered from top to bottom, i.e. the walls 14 and 15, in correspondence with the plate-like portions 8 and 9, are slightly inclined with respect to the vertical, with a reduction in the thickness of the plate-like portions from above. downward.
Ne consegue che il condensatore forma con la parete 4 del frigorifero una intercapedine 26, a camino, di sezione riducentesi dal basso verso l'alto. Analoga intercapedine, non rappresentata in figura, è destinata a formarsi tra il condensatore e il muro. It follows that the condenser forms a chimney-like cavity 26 with the wall 4 of the refrigerator, with a section reducing from bottom to top. A similar gap, not shown in the figure, is intended to form between the condenser and the wall.
E<1 >importante notare che l'acqua contenuta nella porzione tubolare, nella quale è confinata la serpentina, si trova assoggettata ad una corrente ascendente nella direzione della freccia A, e che l'acqua contenuta nelle porzioni piastriformi 8 e 9 si trova assoggettata ad una corrente discendente indicata con le frecce B, con formazione, nel complesso, di una circolazione a termosifone indicata con C, per l'acqua, interessante i collettori 10 e 11, nei quali la corrente ascendente e le correnti discendenti cambiano senso di percorrenza. It is important to note that the water contained in the tubular portion, in which the coil is confined, is subjected to an ascending current in the direction of the arrow A, and that the water contained in the plate-like portions 8 and 9 is subjected to a descending current indicated with the arrows B, with the formation, on the whole, of a radiator circulation indicated by C, for the water, involving the collectors 10 and 11, in which the ascending current and the descending currents change direction of travel .
Il condensatore secondo la presente invenzione presenta l'importante vantaggio di essere del tutto esente da fenomeni di corrosione, di talché c'è da attendersi una sua durata di funzionamento pressocchè indefinita . The condenser according to the present invention has the important advantage of being completely free from corrosion phenomena, so that an almost indefinite operating life is to be expected.
Inoltre e nel contempo il condensatore secondo la presente invenzione risulta di realizzazione semplice e rapida, con attrezzature di limitata complessità. Di conseguenza si presta ad essere costruito in serie comunque grandi con investimenti non elevatissimi, a tutto vantaggio del contenimento dei costi. Moreover and at the same time the condenser according to the present invention is simple and quick to manufacture, with equipment of limited complexity. Consequently, it lends itself to being built in large series with not very high investments, all to the advantage of cost containment.
E' infine da notare che il condensatore secondo la presente invenzione presenta un rendimento energetico elevato. Infatti, il basso coefficiente di scambio termico della plastica è ampiamente compensato dalla aumentata efficienza dello scambio termico dovuta alla circolazione a termosifone, alle corrugazioni , che aumentano la superficie di scambio termico, e alla rastremazione, che provoca moti turbolenti nell'aria ascendente nelle intercapedini. Ovviamente, al condensatore descritto nell'esempio sopra riportato con riferimento alle figure, un tecnico del ramo, allo scopo di soddisfare esigenze contingenti e specifiche, potrà apportare numerose modifiche e varianti, tutte peraltro contenute nell'ambito di protezione dell'invenzione, quale definito dalle seguenti rivendicazioni. Finally, it should be noted that the capacitor according to the present invention has a high energy efficiency. In fact, the low heat exchange coefficient of plastic is amply compensated by the increased efficiency of the heat exchange due to the thermosiphon circulation, to the corrugations, which increase the heat exchange surface, and to the tapering, which causes turbulent motions in the rising air in the cavities. . Obviously, a person skilled in the art, in order to satisfy contingent and specific needs, can make numerous modifications and variations to the capacitor described in the example reported above with reference to the figures, all of which are contained within the scope of protection of the invention, as defined. from the following claims.
