Forma oggetto del presente trovato uno scambiatore di calore, in particolare utilizzabile come scaldasalviette, comprendente almeno una batteria di corpi tubolari collegati ad un collettore di mandata che li alimenta con un fluido riscaldante. Il collettore è provvisto al suo interno di un condotto diffusore, al fine di garantire una sostanzialmente equa distribuzione del fluido riscaldante all’interno dei corpi tubolari. The present invention relates to a heat exchanger, in particular usable as a towel warmer, comprising at least a battery of tubular bodies connected to a delivery manifold which feeds them with a heating fluid. The manifold is provided internally with a diffuser duct, in order to ensure a substantially equal distribution of the heating fluid inside the tubular bodies.
Nel settore degli impianti termosanitari domestici, sono noti scambiatori di calore per il riscaldamento dell’ambiente e della biancheria da bagno costituiti da tubi di metallo attraversati da un fluido riscaldante, generalmente acqua calda. In the field of domestic thermo-sanitary systems, heat exchangers are known for heating the environment and bathroom linen consisting of metal pipes crossed by a heating fluid, generally hot water.
Il calore trasportato dal fluido viene ceduto alle pareti metalliche dei tubi e successivamente disperso nell’ambiente e/o ceduto alla biancheria. The heat transported by the fluid is transferred to the metal walls of the pipes and subsequently dispersed into the environment and / or transferred to the linen.
La quantità di calore scambiato è in funzione della differenza di temperatura esistente tra il fluido riscaldante e l’ambiente, della natura del metallo, del moto del fluido rispetto alle pareti e della geometria e dimensioni dello scambiator The amount of heat exchanged is a function of the temperature difference existing between the heating fluid and the environment, the nature of the metal, the motion of the fluid with respect to the walls and the geometry and dimensions of the exchanger

H tempo necessario allo scambiatore di calore per raggiungere la temperatura di regime, nonché refficienza energetica dello scambiatore medesimo, sono un fattore essenziale per il comfort degli utenti e determinante per il risparmio energetico. The time required for the heat exchanger to reach the operating temperature, as well as the energy efficiency of the exchanger itself, are an essential factor for the comfort of the users and decisive for energy savings.
Generalmente, Γ efficienza energetica e la velocità di raggiungimento della temperatura di regime sono molto limitate negli scambiatori di calore attualmente in commercio, a causa della difficoltà di provocare un moto sufficientemente turbolento del fluido riscaldante. Generally, energy efficiency and the speed of reaching the operating temperature are very limited in the heat exchangers currently on the market, due to the difficulty of causing a sufficiently turbulent motion of the heating fluid.
Scopo del presente trovato è quello di eliminare i suddetti inconvenienti rendendo disponibile uno scambiatore di calore, in particolare utilizzabile come scaldasalviette, ad alto rendimento energetico ed in grado di raggiungere rapidamente la temperatura di regime. The purpose of the present invention is to eliminate the aforementioned drawbacks by making available a heat exchanger, in particular usable as a towel warmer, with high energy efficiency and capable of rapidly reaching the operating temperature.
Un altro scopo del presente trovato è quello di proporre uno scambiatore di calore che sia economico da produrre e possa costituire elemento di arredo. Another object of the present invention is to propose a heat exchanger which is economical to produce and can constitute a piece of furniture.
Detti scopi sono pienamente raggiunti dallo scambiatore di calore oggetto del presente trovato, che si caratterizza per quanto contenuto nelle rivendicazioni sotto riportate ed in particolare per il fatto che il condotto diffusore presenta una bocca di efflusso inclinata rispetto ad un asse longitudinale del condotto diffusore medesimo. Said purposes are fully achieved by the heat exchanger object of the present invention, which is characterized by the contents of the claims reported below and in particular by the fact that the diffuser duct has an outflow mouth inclined with respect to a longitudinal axis of the diffuser duct itself.
Questa ed altre caratteristiche risulteranno meglio evidenziate dalla descrizione seguente di ima preferita forma di realizzazione illustrata, a puro titolo esemplificativo e non limitativo, nella unita tavola di disegno, in cui: This and other characteristics will be better highlighted by the following description of a preferred embodiment illustrated, purely by way of non-limiting example, in the accompanying drawing table, in which:
- la figura 1 illustra una vista frontale globale di uno scambiatore di calore secondo il trovato; Figure 1 illustrates an overall front view of a heat exchanger according to the invention;
- le figure 2 e 3 illustrano rispettivamente una vista laterale ed una vista in pianta, con alcune parti asportate per meglio evidenziarne altre, di un particolare di un condotto di mandata con alFintemo un condotto diffusore per lo scambiatore di calore 91.Ι1006.42.ΓΓ.9 ML/SG/ca Ing. Stefi(∞3⁄4i Figures 2 and 3 show respectively a side view and a plan view, with some parts removed to better highlight others, of a detail of a delivery duct with a diffuser duct inside for the heat exchanger 91.Ι1006.42. ΓΓ.9 ML / SG / ca Ing. Stefi (∞3⁄4i
mostrato in.figura 1. shown in figure 1.
Con riferimento alle figure, lo scambiatore di calore è globalmente indicato con il numero 1 e viene preferibilmente realizzato in acciaio e/o in rame e/o in alluminio. With reference to the figures, the heat exchanger is globally indicated with the number 1 and is preferably made of steel and / or copper and / or aluminum.
Nella forma realizzativa preferita, lo scambiatore 1 comprende quattro batterie 2, 3, 4, 5 di corpi tubolari 6 collegati ad un collettore 7 di mandata che li alimenta con un fluido riscaldante in pressione, preferibilmente acqua calda con pressione di mandata dell’ordine di 10 bar. fi collettore 7 è provvisto al suo interno di un condotto diffusore 8, al fine di garantire ima sostanzialmente equa distribuzione del fluido riscaldante all’interno dei corpi tubolari 6 delle varie batterie. In the preferred embodiment, the exchanger 1 comprises four batteries 2, 3, 4, 5 of tubular bodies 6 connected to a delivery manifold 7 which feeds them with a heating fluid under pressure, preferably hot water with a delivery pressure of the order of 10 bar. The manifold 7 is provided internally with a diffuser duct 8, in order to ensure a substantially equal distribution of the heating fluid within the tubular bodies 6 of the various batteries.
fi condotto diffusore 8 presenta una bocca 9 di efflusso originalmente inclinata rispetto ad un asse longitudinale del condotto diffusore medesimo. Nell’esempio illustrato, l’inclinazione della bocca 9 di efflusso è preferibilmente compresa tra circa 20° e 60° ed il condotto diffusore 8 ha uno spessore preferibilmente compreso tra 0,5±0,2 millimetri e 2,5±0,2 millimetri. The diffuser duct 8 has an outflow mouth 9 originally inclined with respect to a longitudinal axis of the diffuser duct itself. In the illustrated example, the inclination of the outflow mouth 9 is preferably between about 20 ° and 60 ° and the diffuser duct 8 has a thickness preferably between 0.5 ± 0.2 mm and 2.5 ± 0.2 millimeters.
Nella forma realizzativa preferita, il condotto diffusore 8 presenta una sezione trasversale sostanzialmente circolare e pertanto la bocca 9 di efflusso, essendo inclinata, assume una forma sostanzialmente ellittica. H collettore 7, invece, presenta una sezione trasversale preferibilmente ellittica. In the preferred embodiment, the diffuser duct 8 has a substantially circular cross section and therefore the outflow mouth 9, being inclined, assumes a substantially elliptical shape. The manifold 7, on the other hand, has a preferably elliptical cross section.
Il condotto diffusore 8 si sviluppa all’intemo del collettore 7 per una lunghezza sufficiente a garantire la circolazione dell’acqua calda in tutti corpi tubolari 6 di ciascuna batteria. Infatti, l’acqua calda scorre nel diffusore 8 fino ad arrivare in corrispondenza della bocca 9 di efflusso, dalla quale fuoriesce ed entra in una porzione terminale del collettore 7, in modo tale da fluire nei corpi tubolari 6 più distanti dalla zona di afflusso dell’acqua calda. The diffuser duct 8 develops inside the manifold 7 for a sufficient length to ensure the circulation of hot water in all tubular bodies 6 of each battery. In fact, the hot water flows into the diffuser 8 until it reaches the outflow mouth 9, from which it comes out and enters a terminal portion of the manifold 7, in such a way as to flow into the tubular bodies 6 further away from the inflow area of the 'hot water.
La presenza di una bocca 9 di efflusso inclinata instaura un campo 91.Ι1006.42.ΓΓ.9 ML/SG/ca Ing. Sti otra Alb BM The presence of an inclined outflow port 9 establishes a field 91.Ι1006.42.ΓΓ.9 ML / SG / ca Ing. Sti otra Alb BM
fluidodinamico tale da provocare la transizione del regime di moto del fluido da laminare a turbolento, consentendo in tal modo uno scambio termico più efficace tra l’acqua calda e le pareti dei corpi tubolari 6. fluid dynamics such as to cause the transition of the motion regime of the fluid from laminar to turbulent, thus allowing a more effective heat exchange between the hot water and the walls of the tubular bodies 6.
In una seconda forma di realizzazione (non illustrata) si prevede che il condotto diffusore 8 abbia una sezione trasversale sostanzialmente rettangolare che mantiene tale forma, eventualmente solo più allungata, anche in corrispondenza della bocca 9 di efflusso. In a second embodiment (not shown) the diffuser duct 8 is provided to have a substantially rectangular cross section which maintains this shape, possibly only more elongated, also in correspondence with the outflow mouth 9.
In una terza forma di realizzazione (non illustrata), si prevede che la bocca 9 di efflusso, vista in un piano longitudinale parallelo all’asse del condotto diffusore 8, abbia una doppia inclinazione e sia sostanzialmente sagomata a V rovescia. In a third embodiment (not shown), it is expected that the outflow mouth 9, seen in a longitudinal plane parallel to the axis of the diffuser duct 8, has a double inclination and is substantially shaped like an inverted V.
In una quarta forma di realizzazione (non illustrata), la bocca 9 di efflusso, vista in un piano longitudinale parallelo all’asse del condotto, è sagomata sostanzialmente In a fourth embodiment (not shown), the outflow mouth 9, seen in a longitudinal plane parallel to the axis of the duct, is substantially shaped
a W. to W.
La forma di realizzazione preferita prevede che le quattro batterie 2, 3, 4, 5 siano costituite rispettivamente da tredici, dieci, cinque e cinque corpi tubolari 6. The preferred embodiment provides that the four batteries 2, 3, 4, 5 are constituted respectively by thirteen, ten, five and five tubular bodies 6.
Infine, le batterie 2, 3, 4, 5 risultano collegate ad un secondo collettore 10 di ritorno del fluido riscaldante. Finally, the batteries 2, 3, 4, 5 are connected to a second manifold 10 for the return of the heating fluid.
Il trovato consegue importanti vantaggi. The invention achieves important advantages.
Innanzitutto, un tale scambiatore di calore, grazie all’elevato grado di turbolenza generato nel fluido riscaldante dalla bocca di efflusso inclinata, presenta un alto rendimento energetico ed è in grado di raggiungere rapidamente la temperatura di regime. First of all, such a heat exchanger, thanks to the high degree of turbulence generated in the heating fluid by the inclined outflow mouth, has a high energy efficiency and is able to quickly reach the operating temperature.
Vantaggiosamente, lo scambiatore di calore in oggetto è economico da produrre e può costituire elemento di arredo. Advantageously, the heat exchanger in question is cheap to produce and can be a piece of furniture.
