Definitions
- the invention relates to a heat exchanger for exchange heat between a first fluid and a second fluid, comprising a stack of mutually aligned pockets in a longitudinal direction, and having two boxes collectors mutually juxtaposed in one direction lateral, each formed by alignment, in the direction longitudinal, of entry or exit chambers belonging respectively to the different pockets, the manifolds being subdivided as a whole into at least three connecting pipes, connecting pipes that belong to the same manifold in succession in the longitudinal direction and not communicating directly between them, while in each connecting line the entry or exit rooms communicate with each other by openings in the walls of the pockets, pockets defining a route for the first fluid between an upstream connection pipe adjacent to a first longitudinal end of the stack and a downstream link adjacent to the second longitudinal end of the stack, passing alternately from a connection belonging to one of the manifolds to a connecting pipe belonging to the other manifold, via U-shaped paths, each of which connects between they the entry and exit chambers of the same pocket, the upstream and downstream connecting pipes being connected to
- the pockets are each formed two stamped sheet metal plates in the form of bowls, of which the concavities are turned towards each other and which are mutually tightly connected at their periphery, the entry and exit rooms being delimited by bowl regions of greater depth than remaining regions, so as to reserve between two pockets neighboring, opposite said remaining regions, an interval for the passage of the second fluid in the lateral direction, and said openings being formed in the bottoms of the cuvettes, which are in tight mutual contact around the openings.
- the two bowls of each pocket are in further tightly connected in a middle area of their width and over a substantial fraction of their length from a first end edge, the two branches of said path in U extending on either side of said central zone, as well as said deeper regions of bowls, arranged in the vicinity of said first end edge.
- the object of the invention is to improve the characteristics of operation of these evaporators.
- the invention relates in particular to a heat exchanger of the kind defined in the introduction, and provides that said tubing is eccentric with respect to said openings.
- the illustrated evaporator intended for an air conditioning system of the passenger compartment of a motor vehicle, includes a multiple pockets 1 mutually stacked in one substantially horizontal longitudinal direction, and formed each of two stamped sheet metal plates cuvettes 2 and 3. These are identical to each other and have their concavities turned towards each other, either towards second and first ends respectively longitudinal 5, 4 of the stack.
- Each bowl has a peripheral edge 6 situated in a vertical plane, and the peripheral edges 6 of the two bowls forming a pocket are mutually assembled in a fluid-tight manner, by soldering, to define the interior volume of the pouch.
- Each bowl also has, at its upper part, two regions 7 of greater depth than that of the remaining region 8, the latter occupying most of the height of the bowl, below regions 7.
- each bowl juxtaposed from left to right of the figures, define in each pocket an entry room and a room outlet for the refrigerant.
- the entrance room and the outlet chamber of each pocket are separated one on the other by a tight junction zone 9 between the two halfway down the pocket, this junction area connecting to edge 6 at the upper end 10 of the pocket and extending down to the vicinity of the lower end of the cover so as to define in this one, in relation to the regions 8 of the basins, a journey in U for the fluid between the inlet chamber and the exit.
- the bottom of each bowl is crossed, in each regions 7 of greater depth, through an opening 11 and the bottoms facing one another of a bowl 2 and of an adjacent 3 bowl are mutually linked so waterproof around the openings, by soldering.
- the alignment of the inlet / outlet chambers located on the side left of the figures forms a manifold 16, and the alignment of the inlet / outlet chambers located on the side right forms a manifold 17.
- the manifold 16 is subdivided by a transverse partition 18 into a connecting line 12 extending from this partition at the end 4 of the stack and a connecting pipe 14 extending from the bulkhead to the end 5.
- a bulkhead transverse 19 further from the end 4 than the partition 18, separates the manifold 17 into a link 13 adjacent to the end 4 and a link 15 adjacent to the end 5.
- End plates 20 and 21 are brazed to the bottom of the cups 2,3 located at the ends 4.5 of the stack respectively so to close the openings 11 of these bowls, and contribute to delimit the connecting pipes.
- the entry / exit rooms forming a single connecting pipe communicate between them by the openings 11 of the bowls 2,3.
- An inlet pipe 22 extends over the entire length of the connecting pipe 14 and crosses the end plate 21 and the intermediate partition 18, to which it is soldered, so as to put in communication the connecting line 12 with the part of the circuit refrigerant located upstream of the evaporator.
- a outlet pipe 23 also passes through plate 21 and opens into the connecting pipe 15, so as to put this in communication with the downstream part of the circuit.
- the refrigerant entering the connection line 12 through the tubing 22 then passes into the line of link 13, using U-shaped paths in parallel of a first group of covers. It is then transferred to the connecting pipe 14, via the paths at U of a second group of sleeves, then driving link 15, via the U-shaped paths of a third and last group of covers.
- the fluid leaves finally the evaporator through the pipe 23.
- the fluid receives heat of an air flow which crosses the evaporator horizontally from right to left, along arrow F1, passing through the intervals between the pockets next to the 8 regions of the bowls.
- the tubing 22 is offset from the centers of the openings 11 of the bowls which define the manifold 16.
- the tubing is shifted to the left, i.e. downstream by in relation to the air flow F1.
- the outline of each opening 11 has an oval shape and is composed of two horizontal straight lines 30 and two semicircles 31 whose concavities are turned one towards the other and which are tangent to the segments 30.
- the tubing 22 has an outside diameter equal to the diameter of the semicircles 31 and comes to rest on the edge of the openings it cross, and is brazed to this edge, over the entire length of the semicircle 31 located on the left.
- the diameter of the tubing 22 is less than that of the semicircles 31, the contact then being substantially punctual.
- the dotted line curve and the solid line curve respectively relate to the illustrated evaporator and to an evaporator different from this by the fact that the axis of the tubing 22 passes through the centers of the openings it crosses.
- the curves of Figure 3 and those of Figure 4 respectively show the heat output exchanged in kW and the temperature of the outgoing air in ° C, depending on the air flow rate in kilograms / hour passing through the evaporator, the air temperature incoming being 30 ° C.
- the arrangement according to the invention also improves the homogeneity heat exchange in the evaporator volume, and therefore the homogeneity of the distribution of temperature within the air flow leaving it, with attenuation of the phenomena of hot spots and points cold.
- brazing of the tubing at the edges of the openings causes stiffening and reduction of operating noise.
- the tubing can be partially offset from the centers of the openings without reaching the lateral ends thereof. She can be offset towards the middle of the width of the evaporator, and not outwards. It can be shifted to downstream with respect to the air flow, or transversely with compared to this one. It is not necessarily soldered to edge of openings.
- the offset tubing according to the invention may be an outlet pipe in communication with the downstream link pipe. It is also possible to provide an odd number of connecting pipes, the inlet and the fluid outlet being carried out on the same side of the evaporator, left or right with reference to Figures 1 and 2.
- the evaporator can also operate in one orientation in the space different from that described.
