The present invention generally refers to the field of heat exchangers for automotive applications, and more specifically to heat exchangers comprising distributors formed by metal tubular containers.
In tale tipo di scambiatori, ? stato notato che il processo di produzione fa s? che le piastre laterali, che servono per rinforzare il pacco costituito dallo scambiatore di calore, in genere hanno estremit? che sono separate dai distributori da gap di entit? variabile. Tale fatto ? indesiderato da un punto di vista strutturale. In this type of exchangers, ? been noticed that the production process does s? that the side plates, which are used to reinforce the package consisting of the heat exchanger, generally have extremities? which are separated from the distributors by entity gaps? variable. Such a fact ? undesirable from a structural point of view.
Uno scopo della presente invenzione ? quello di rendere disponibile un accorgimento per compensare le tolleranze dello scambiatore di calore e garantire un adeguato contatto fra piastra laterale e distributore. A fronte di tale scopo, secondo la presente invenzione si propone una disposizione di assemblaggio angolare per uno scambiatore di calore, comprendente un distributore includente un recipiente tubolare metallico, e An object of the present invention ? that of providing a device to compensate for the tolerances of the heat exchanger and ensure adequate contact between the side plate and the distributor. For this purpose, according to the present invention an angular assembly arrangement for a heat exchanger is proposed, comprising a distributor including a metal tubular container, and
una piastra laterale costituita da una lamina metallica piana che si estende ortogonalmente al distributore ed ? fissata all?estremit? di esso, a side plate made up of a flat metal sheet which extends orthogonally to the distributor and is fixed at? the extremity? its,
in cui la piastra laterale comprende una linguetta terminale che si estende a zigzag da una rispettiva estremit? della piastra laterale e comprende un?estremit? di appoggio a contatto con una parete del distributore, detta estremit? di appoggio presentando, secondo una vista in pianta, una concavit? configurata per adattarsi alla parete del distributore. wherein the sideplate includes an end tab extending in a zigzag pattern from a respective end? of the side plate and includes a? end? support in contact with a wall of the distributor, said extremity? of support presenting, according to a plan view, a concavity? configured to fit the dispenser wall.
Con la disposizione secondo l?invenzione, la linguetta terminale agisce da adattatore per la tolleranza del pacco in piantaggio. Inoltre, la sagoma sulla circonferenza del distributore, cooperando con l?estremit? di appoggio della linguetta terminale impedisce alla piastra laterale di spostarsi durante il processo di produzione. Vantaggiosamente, la disposizione secondo l?invenzione ? inoltre migliorativa per le pressioni di scoppio. With the arrangement according to the invention, the end tab acts as an adapter for the tolerance of the pack being pressed.

la figura 1 rappresenta una vista in elevazione frontale di una porzione d?angolo di uno scambiatore di calore secondo l?invenzione; Figure 1 is a front elevational view of a corner portion of a heat exchanger according to the invention;
la figura 2 rappresenta una vista in scala ingrandita di un?altra porzione d?angolo dello scambiatore di calore di figura 1; FIG. 2 is an enlarged view of another corner portion of the heat exchanger of FIG. 1;
le figure 3 e 4 rappresentano rispettivamente una vista prospettica e una vista in pianta di un assieme distributore/piastra laterale; e Figures 3 and 4 are respectively a perspective view and a plan view of a distributor/side plate assembly; And
le figure 5-7 rappresentano rispettivamente una vista prospettica, una vista in pianta e una vista in sezione (presa lungo la linea B-B di figura 6) di una piastra laterale. Figures 5-7 are respectively a perspective view, a plan view and a sectional view (taken along the line B-B of Figure 6) of a side plate.
Con riferimento alle figure 1 e 2, ? rappresentato uno scambiatore di calore per applicazioni automobilistiche, indicato complessivamente con 1. With reference to figures 1 and 2, ? represented a heat exchanger for automotive applications, indicated as a whole with 1.
Lo scambiatore di calore 1 comprende una pluralit? di tubi paralleli 11 estendentisi fra due lati opposti dello scambiatore di calore (rispettivamente rappresentati nelle figure 1 e 2), e un primo ed un secondo distributore 13, 15 rispettivamente disposti in corrispondenza di ciascuno di detti due lati opposti dello scambiatore di calore. I tubi 11 sono fluidicamente collegati ai distributori 13, 15 per il trasporto di un fluido frigorigeno per consentire a tale fluido di scambiare energia termica con un fluido gassoso, in particolare aria, il quale viene fatto passare fra i tubi 11 in una direzione sostanzialmente perpendicolare al piano definito dal fascio di tubi 11. A tal fine, fra tubi 11 adiacenti sono interposte alettature 17. The heat exchanger 1 comprises a plurality? of parallel pipes 11 extending between two opposite sides of the heat exchanger (respectively represented in Figures 1 and 2), and a first and a second distributor 13, 15 respectively arranged at each of said two opposite sides of the heat exchanger. The pipes 11 are fluidically connected to the distributors 13, 15 for the transport of a refrigerant fluid to allow this fluid to exchange thermal energy with a gaseous fluid, in particular air, which is made to pass between the pipes 11 in a substantially perpendicular direction to the plane defined by the bundle of pipes 11. For this purpose, fins 17 are interposed between adjacent pipes 11.
Nelle figure 3 e 4 ? rappresentata per comodit? una sola estremit? di un solo distributore, ma si intende che l?estremit? non mostrata e il distributore non mostrato presentano una struttura analoga a quella visibile nei disegni. In figures 3 and 4 ? represented for convenience? only one end? of a single distributor, but it is understood that the? end? not shown and the vending machine not shown have a structure analogous to that visible in the drawings.
Ciascun distributore 13, 15 include un recipiente tubolare metallico 13a, 15a estendentesi lungo un rispettivo asse longitudinale z, e un elemento di chiusura terminale 13b, anch?esso di materiale metallico, disposto a ciascuna estremit? del recipiente tubolare 13a, 15a (nelle figure per comodit? ? mostrata una sola estremit? dei distributori). Each distributor 13, 15 includes a metal tubular container 13a, 15a extending along a respective longitudinal axis z, and an end closure element 13b, also of metal material, arranged at each end? of the tubular container 13a, 15a (for convenience, only one end of the distributors is shown in the figures).
Lo scambiatore di calore 1 comprende inoltre una prima e una seconda piastra laterale 19 (?fianchetto?) disposte ciascuna in corrispondenza di un rispettivo ulteriore lato dello scambiatore di calore, ortogonale ai due lati opposti dello scambiatore di calore ai quali sono disposti i distributori 13, 15. Nelle figure ? rappresentata una sola di tali piastre 19, ma si intende che quella non mostrata presenta una struttura analoga a quella visibile nei disegni. The heat exchanger 1 also comprises a first and a second side plate 19 (?side panel?) each arranged at a respective further side of the heat exchanger, orthogonal to the two opposite sides of the heat exchanger at which the distributors 13 are arranged , 15. In the figures ? only one of these plates 19 is shown, but it is understood that the one not shown has a structure similar to that visible in the drawings.
Ciascuna piastra laterale 19 ? costituita da una lamina metallica piana che si estende ortogonalmente ai distributori 13, 15, e presenta a ciascuna sua estremit? una linguetta terminale 21 avente un?ampiezza inferiore all?ampiezza della parte restante della piastra laterale 19. Each side plate 19 ? consisting of a flat metal lamina which extends orthogonally to the distributors 13, 15, and has at each end an end tab 21 having a width smaller than the width of the remainder of the side plate 19.
In generale l?unione strutturale fra i vari componenti metallici dello scambiatore sopra descritto ? ottenuta per accoppiamento di materiale, ad esempio mediante saldatura e/o brasatura. In general, the structural union between the various metal components of the exchanger described above? obtained by coupling of material, for example by welding and/or brazing.
In particolare, con riferimento alle figure da 3 a 7, in corrispondenza di ciascuno degli angoli dello scambiatore di calore 1, ciascuna estremit? dei distributori 13 e 15 ? unita a una rispettiva delle piastre 19 nel modo seguente. In particular, with reference to figures 3 to 7, at each of the corners of the heat exchanger 1, each end? of distributors 13 and 15 ? joined to a respective one of the plates 19 in the following manner.
Ciascuna linguetta terminale 21 si estende a zigzag dalla rispettiva estremit? della piastra laterale 19 e comprende un?estremit? di appoggio 21a a contatto con la parete del recipiente tubolare 13a, 15a. Come si pu? osservare in particolare nelle figure 4 e 6, l?estremit? di appoggio 21a presenta, secondo una vista in pianta, una concavit? rivolta verso il rispettivo distributore 13, 15 configurata per adattarsi alla curvatura della parete del distributore. Each end tab 21 extends in a zigzag fashion from its respective end? of the side plate 19 and comprises a? end? support 21a in contact with the wall of the tubular container 13a, 15a. How can you? observe in particular in figures 4 and 6, the? extremity? support 21a has, according to a plan view, a concavity? facing the respective distributor 13, 15 configured to adapt to the curvature of the wall of the distributor.
In particolare, la linguetta terminale 21 comprende una parte discendente 21? che si estende dalla piastra laterale 21, e una parte ascendente 21?? che ? collegata alla parte discendente 21? tramite un?ansa 21??? e presenta l?estremit? di appoggio 21a. Ai fini della presente descrizione, con ?discendente? si intende che la relativa parte della linguetta terminale 21 si estende dalla quota della piastra laterale 19 in modo da avvicinarsi al fascio di tubi 11 dello scambiatore di calore 1, terminando nell?ansa 21???, mentre con ?ascendente? si intende che la relativa parte della linguetta terminale 21 si estende dall?ansa 21??? in modo da allontanarsi dal fascio di tubi 11. Tale andamento a zigzag ? riferito pertanto a una direzione parallela all?asse longitudinale z del distributore 13, 15, ovvero alla direzione dello spessore della piastra laterale 19. In particular, the end tab 21 comprises a descending part 21? extending from the side plate 21, and an ascending portion 21?? That ? connected to the descendant part 21? through a? loop 21??? and presents the? extremity? support 21a. For the purposes of this description, with ?descendant? it is meant that the relative part of the end tab 21 extends from the level of the lateral plate 19 so as to approach the bundle of pipes 11 of the heat exchanger 1, ending in the bend 21???, while with ?ascending? it is meant that the relative part of the terminal tab 21 extends from the loop 21??? so as to move away from the bundle of pipes 11. This zigzag pattern ? therefore referring to a direction parallel to the longitudinal axis z of the distributor 13, 15, or to the direction of the thickness of the side plate 19.
Con la disposizione sopra descritta, la linguetta terminale 21 agisce da adattatore per la tolleranza nelle distanze fra piastra laterale e distributore. Inoltre, la sagoma curva del distributore, cooperando con l?estremit? di appoggio 21a della linguetta terminale 21 impedisce alla piastra laterale 19 di spostarsi durante il processo di produzione. With the arrangement described above, the end tab 21 acts as an adapter for the tolerance in the distances between the side plate and the distributor. Furthermore, the curved shape of the distributor, cooperating with the? bearing 21a of the end tab 21 prevents the side plate 19 from moving during the production process.
