DESCRIZIONE DESCRIPTION
La presente invenzione si riferisce ad uno scambiatore di calore, quale un evaporatore e/o un condensatore per un apparecchio generatore di freddo, del tipo comprendente una serpentina per un fluido frigorigeno. The present invention relates to a heat exchanger, such as an evaporator and / or a condenser for a cold-generating apparatus, of the type comprising a coil for a refrigerant fluid.
La presente invenzione si pone il problema di mettere a disposizione uno scambiatore il quale permetta di conseguire un migliorato rendimento del ciclo e che sia nel contempo costruttivamente semplice. The present invention poses the problem of providing an exchanger which allows to achieve an improved efficiency of the cycle and which is at the same time constructively simple.
Tale problema è risolto da uno scambiatore di calore del tipo specificato, il quale si caratterizza l per il fatto di comprendere un accumulatore termico in relazione di scambio termico con la serpentina. This problem is solved by a heat exchanger of the specified type, which is characterized in that it comprises a heat accumulator in a heat exchange relationship with the coil.
Ulteriori caratteristiche e i vantaggi dello scambiatore di calore secondo la presente invenzione risulteranno dalla descrizione di seguito riportata di un suo esempio di realizzazione, dato a titolo indicativo e non limitativo, con riferimento alle annesse figure, in cui: Further characteristics and advantages of the heat exchanger according to the present invention will result from the description given below of an example of its embodiment, given by way of non-limiting example, with reference to the attached figures, in which:
la fig. 1 rappresenta una vista in ,prospettiva, in parziale sezione, di uno scambiatore di calore secondo l'invenzione, e fig. 1 represents a perspective view, in partial section, of a heat exchanger according to the invention, and
-- la fig. 2 rappresenta una vista in sezione dello scambiatore di calore di figura 1, fatta secondo la linea II-II. - fig. 2 represents a sectional view of the heat exchanger of Figure 1, taken along the line II-II.
Con riferimento alle annesse figure, con 1 è globalmente indicato uno scambiatore di calore, nell'esempio un evaporatore, per un apparecchio generatore di freddo, quale un frigorifero, un congelatore, una combinazione dei due e simili. With reference to the attached figures, the reference numeral 1 globally indicates a heat exchanger, in the example an evaporator, for a cold-generating appliance, such as a refrigerator, a freezer, a combination of the two and the like.
Lo scambiatore di calore 1 comprende una serpentina 2, destinata a essere percorsa da un fluido frigorigeno, e un accumulatore termico 3, avente elevata capacità termica, in relazione di scambio termico con la serpentina 2. The heat exchanger 1 comprises a coil 2, intended to be traversed by a refrigerant fluid, and a heat accumulator 3, having a high thermal capacity, in a heat exchange relationship with the coil 2.
La serpentina 2 è formata da un tubo 4, metallico, avente tratti terminali,entrambi indicati con 5 The coil 2 is formed by a metal tube 4 having terminal portions, both indicated with 5
L'accumulatore termico 3 comprende un serbatoio 6, formato da due lastre metalliche, e precisamente da una lastra 7, piana, e da una lastra 8, sostanzialmente conformata a vaschetta, per imbutitura. Le lastre 7 e 8 sono tra loro saldate lungo' rispettivi bordi periferici 9 e 10, con definizione, tra rispettive facce interne 11 e 12 tra loro affacciate, di una camera 13. L'accumulatore termico 3 comprende inoltre una sostanza 14, avente elevata capacità termica, la quale è posta nella camera 13. La sostanza 14 nell'esempio è un miscuglio di acqua e alcole. The thermal accumulator 3 comprises a tank 6, formed by two metal plates, and precisely by a flat plate 7 and by a plate 8, substantially tray-shaped, for drawing. The plates 7 and 8 are welded together along the respective peripheral edges 9 and 10, defining a chamber 13 between respective internal faces 11 and 12 facing each other. The thermal accumulator 3 further comprises a substance 14, having a high heat capacity, which is placed in chamber 13. The substance 14 in the example is a mixture of water and alcohol.
La serpentina 2 è posizionata internamente al serbatoio 6, ed è ad esso fissata tramite mezzi di fissaggio 15. In particolare la serpentina 2 è in contatto con la faccia interna 11 della lastra piana 7. The coil 2 is positioned inside the tank 6, and is fixed to it by means of fixing means 15. In particular, the coil 2 is in contact with the internal face 11 of the flat plate 7.
I mezzi di fissaggio 15 vantaggiosamente si concretano in due elementi passaparete, entrambi indicati con 16, formati nel serbatoio 6, ciascuno attraversato da un rispettivo tratto terminale 5 della serpentina 2. The fastening means 15 advantageously take the form of two bulkhead elements, both indicated with 16, formed in the tank 6, each crossed by a respective terminal portion 5 of the coil 2.
Ciascun elemento passaparete 16 comprende un collare 17, il quale è formato da contrapposte porzioni dei bordi periferici della lastra, e precisamente da una porzione 18, piana, del bordo periferico 9 della lastra 7 e da una porzione 19, conformata ad U, tramite deformazione per imbutitura, del bordo periferico 10 della lastra 8. Each pass-through element 16 comprises a collar 17, which is formed by opposing portions of the peripheral edges of the sheet, and precisely by a flat portion 18 of the peripheral edge 9 of the sheet 7 and by a U-shaped portion 19, by deformation by drawing, of the peripheral edge 10 of the plate 8.
Le porzioni 18 e 19 sono serrate strettamente sui tratti terminali 5, così da trattenerli saldamente, e di conseguenza da trattenere saldamente la serpentina all'interno del serbatoio. The portions 18 and 19 are tightly tightened on the end portions 5, so as to hold them firmly, and consequently to hold the coil firmly inside the tank.
Preferibilmente tra le porzioni 18 e 19 è previsto un materiale di apporto 20, ad esempio per saldo brasatura, per garantire la tenuta dell'elemento passaparete. A filler material 20 is preferably provided between the portions 18 and 19, for example for brazing, to ensure the seal of the bulkhead element.
Il principale vantaggio dello scambiatore di calore secondo la presente invenzione risiede nel fatto che esso ha permesso di raggiungere un miglioramento del rendimento del ciclo. The main advantage of the heat exchanger according to the present invention lies in the fact that it has made it possible to achieve an improvement in the efficiency of the cycle.
Inoltre esso ha presentato uno scambio termico particolarmente esaltato tra l'accumulatore termico e la serpentina, grazie al fatto che la serpentina è sostanzialmente tutta immersa nella sostanza ad elevata capacità termica contenuta nel serbatoio. Furthermore, it exhibited a particularly enhanced heat exchange between the heat accumulator and the coil, thanks to the fact that the coil is substantially entirely immersed in the high heat capacity substance contained in the tank.
Vi è poi da aggiungere che lo scambiatore di calore secondo l'invenzione è risultato nel contempo di inusitata semplicità strutturale, vantaggio non ultimo per un articolo che deve essere prodotto in grande e grandissima serie. It should also be added that the heat exchanger according to the invention has at the same time resulted in an unusual structural simplicity, an advantage not least for an article that must be produced in large and very large series.
Ovviamente allo scambiatore di calore sopra descritto 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 . Obviously, a person skilled in the art can make numerous modifications and variations to the heat exchanger described above, in order to meet contingent and specific needs, all of which are however contained within the scope of the invention, as defined by the following claims.
