Description

PLQCQ COLECTORQ PUF OCUPQ LITTLE SPACE. PñRfl INTERCflMBIflDOR DF CflLQR The invention relates to a collector plate intended to be assembled in a sealed manner, by an "ar < e to a curtain-shaped flow of fluid, to form at least one chamber suitable for containing a heat-carrying fluid; on the other hand, to a plurality of tubes for the circulation of fluid, which communicate with the chamber (s); the plate comprising a central plate extending substantially along a plane, a peripheral region defining an annular channel 1 for receiving the peripheral edge of the fluid box and, eventually, a seal; and a plurality of inclined annular sleeves, which surround each of the openings of the passage for a tube provided inside the platen; the peripheral region and the sleeves of the line extending, respectively, to one side and to the plane side. In the known collector plates, the peripheral region is attached to a marginal portion of the stage that extends completely around the assembly of the sleeves. The purpose of the invention is to reduce the space occupied by the collector plate with respect to this known method. The invention mainly contemplates a plate col *, t JÍ a A * l jf, nei or ikrthi '> jn i < ? to ii ii U't, provides that, in certain areas of the channel, the profile of the inner side wall of es + e joins directly to the profile of an adjacent sleeve, without going through the direction of dlcho pl no. Other optional features of the invention, complementary or alternative, are listed below: The profiles mentioned, which are mutually joined, are located substantially in the same direction. The sleeves are aligned along a row and have 10 elongated each one perpendicularly following their direction of alignment. The profiles mentioned are attached directly to the level of the two ends of each sleeve. Each sleeve has two longitudinal sides Substantially flat, and the profile of the outer side of each of the end sleeves of the Tile is attached directly to the profile of the equally flat wall of the channel along the entire length of said side. The profile of the flat outer side of each of the? 0 end sleeves is inclined sharply with respect to the general plane of l? plate that the other sides of the handle < you. The flat outer side of each of the end sleeves has the same usual inclination with with respect to the general plane of the plate that the other sides of the man u. * -, v f-o? to a die r? i > you < -o -n '- < t, < d of l. «ncl.

In this case, as in the previous one, the distance between the ex + ruler tube and the channel can be less than or equal to the average passage of the tubes. The invention also has as a goal a heat exchanger, especially for a heating and / or cooling circuit in a motor vehicle, comprising a plate as defined above, assembled in a sealed manner on the one hand to a cuvette-shaped fluid box to form at least one chamber suitable for containing a heat-carrying fluid; on the other hand to a plurality of tubes for the circulation of fluid, which communicate with the chamber (s); said channel receiving the peripheral edge of the fluid channel and, optionally, a seal; said tubes passing through said openings and being tightly surrounded by said sleeves. The features and advantages of the invention will be discussed in greater detail below in the description that follows, in which reference is made to the accompanying drawings, in which: 1 A Figure 1 is an is a perspective, partially detached, showing a collecting plate according to the invention, associated with a fluid box and with a set of uo; - FIG. 2 is a top view of the collector plate illustrated in FIG. 1 and FIGS. 3 to 5 are partial views., in section, tornadoes following the lines TIT-TII, IV-TV and VV of figure 2. The collector plate 1, represented in the figures, formed from embossed metal sheet, comprises a peripheral region 2 that defines a channel annular having an internal side wall 3, a bottom 4 and an external side wall 5. Said channel serves to receive the peripheral edge 6 of a cuvette-shaped fluid box 7, as well as a seal 8. After assembly , the free edge 9 of the external wall 5 is folded by crimping on the edge 6 of the fluid channel, to immobilize it and compress the joint 8 between the edge 6 and the bottom 4 of the channel. The collector plate is shown before crimping in FIGS. 2 to 5. The heat meter partially illustrated in FIG. 1 also comprises a set or bundle of tubes 10, constituted by a row of tubes 11, each of the which has an oblong cross-section, elongated in the direction of the width of the collector plate, separated from one another, over most of its length, by spacers 12 having the shape of corrugated strips. Each tube 11 passes through an opening 13 of corresponding shape, provided in the central region of the collector plate, said opening being surrounded by an inclined sleeve 14. In this way, the end of each tube opens into the interior volume 15 of the fluid box, the separators being located in <; .-! > ? t? lor -lo icho volume. In a known manner, along each of the two major sides of the peripheral channel 3-5, of rectangular outline, the inner wall 3 thereof is joined at the ends of the sleeves 14 by means of a flange 16, oriented substantially perpendicular to the longitudinal direction of the tubes. The two flanges 16 form, with the bottoms of the valleys 17 included between the sleeves 14, a plate that extends substantially along a plane perpendicular to the mentioned direction. Actually, the platen is not completely flat, the ridges 16 having a slightly undulating shape, so as to limit the mechanical stresses during the manufacture of the collector plate-a. According to the invention, the plate does not comprise the flange along the smaller sides of the peripheral channel, wherein the inner wall of the channel is directly joined to the external flank of the end sleeve of the row, to form a single inclined plane 18. This arrangement decreases the volume occupied by the heat exchanger in the longitudinal direction of the collector plate, at twice the length of the edge 16. In addition, the inclined plane 18 is more inclined with respect to the general plane of the stage than the plates. the other flanks of the sleeves 14, which still further reduces the volume occupied. In view of the radius of the roundings formed by the channel 3-5 at the angles of the reader, the sleeves of the screws. -h directly to the inner wall of the channel, also at its ends, following inclined surfaces 19, so that only the intermediate sleeves are separated from the channel by the flanges 16. In a variant, as indicated in broken line in the 3, the inclined plane 18 can have substantially the same inclination with respect to the general plane of the plate, than the other flanks of the sleeves and form an obtuse dihedral with the wall 3 of the channel, perpendicular to said plane. Another variant provides the direct connection of the sleeves to the walls of the channel no longer over the entire length of the collector plate, but over its entire width, which reduces the space occupied by the heat exchanger in the width direction.
