Definitions
- the invention relates to a heat exchanger defining a combined path for a first fluid formed of a multiplicity first elementary journeys and a combined journey for a second fluid formed by a multiplicity of seconds elementary paths, the first and second paths elementary being arranged alternately in a first direction so that each elementary path for one fluids either in thermal contact with at least one path adjacent elementary for the other fluid, each first basic path with a U-shaped configuration, both of which branches extend in a second direction and are offset from each other in a third direction, the first, second and third directions being substantially perpendicular to each other, each second elementary path extending into the third direction of an entrance face of the exchanger, close to a first branch of the first elementary paths, at a exit face, close to the second branch of the first elementary paths, the two branches of each first elementary path leading into collecting spaces respective, the collecting spaces connected to said first branches and those connected to said second branches being aligned in the first direction in first and second rows respectively, and the collecting spaces communicating two by two so as to establish a combined route extending
- Such heat exchangers are used in particular as as evaporators in vehicle air conditioning loops, the first fluid being a circulating refrigerant in the loop, and the second fluid being air intended for the passenger compartment of the vehicle.
- evaporators in which the refrigerant circulates in a combined path in six passes, a first subset of first elementary paths defining a first pass starting from a first collector space belonging to the second row and a second pass leading to a second collecting space belonging to the first row, a second subset of first elementary paths defining a third pass starting from a third collector space, next to the second collecting space in the first row and communicating with this one, and a fourth pass leading to a fourth collector space next to the first collector space in the second row and separated from it by a partition, and a third subset of first elementary paths defining a fifth pass starting from a fifth collector space next to the fourth collector space in the second row and communicating with it and a sixth pass leading to a sixth collector space next to the third collector space in the first row and separated from it by a partition.
- the refrigerant flows from the second face to the first face of the evaporator, that is to say against the flow of air, while it flows from the first face to the second face, i.e. in the same direction as the air, between the third pass and the fourth pass.
- the object of the invention is in particular to improve the characteristics evaporator refrigerators, both in terms of cooling capacity in terms of homogeneity of the temperature of the cooled air of a second elementary path to the other.
- the invention relates in particular to a heat exchanger of the kind defined in the introduction, and provides that at least one passage of transition is made between two collecting spaces belonging respectively in the two rows, so that, in the first elementary journeys communicating directly with these two collecting spaces, the fluid circulates from one branch to another in the same direction compared to the third direction.
- Figure 1 is a top view in section of an evaporator according to the invention.
- Figure 2 is a graph showing performance respective refrigerators of an evaporator according to the invention and a conventional circuit evaporator.
- FIG. 1 represents an evaporator according to the invention, in section along the plane passing through the axes of the two rows collector spaces.
- This evaporator consists essentially of by a stack of pockets and dividers corrugated as described for example in FR 2 747 462 A, to which we can refer for more details on the structure of this stack.
- Each pocket 1 is formed of two stamped sheet metal plates in the form of bowls 2 and 3. These are identical to each other and have their concavities facing one another, that is to say respectively to the right and to the left of the figure.
- Each bowl has a peripheral edge 4 located in a perpendicular plane to that of the figure, and the peripheral edges 4 of the two bowls forming a pocket are mutually assembled in a fluid-tight manner, for example by soldering, to define the interior volume of the pouch.
- Each pocket has two head regions 5 and 6, located respectively down and up in the figure, defined by deep-drawn plates 2, 3. The lead regions 5 and 6 occupy a minority fraction of the height of the evaporator at the top of it, the rest of the height, behind the plane of the figure, being occupied by a thinner body region.
- regions 5 and 6 of each pocket are separated from each other by a zone of tight junction 7 between the two bowls at mid-width of the pocket, this junction zone extending downwards to the vicinity of the lower end of the pocket so as to define in the body region thereof a elementary U-shaped path for the refrigerant between these two volumes.
- a neighboring plate 2 and a neighboring plate 3 belonging with two different pockets are in mutual support by their funds 8 in regions 5 and 6, and separated one of the other, in the body region, by a trimmed interval a wavy interlayer defining an elementary path for the air to be cooled, parallel to the plane of the figure, according to arrow F1. Funds 8 in mutual contact are brazed together and some of them are crossed by openings 9 making the volumes communicate with each other corresponding interiors.
- the evaporator comprises an inlet insert of fluid 10 and a fluid outlet insert 11 which are stacked with pockets 1, each insert being interposed between regions 5 and 6 of a pocket on the one hand and the regions 5 and 6 of another pocket on the other hand.
- the inserts 10 and 11 are for example of the type described in FR 2 757 618 A. Inserts 10 and 11 are both identical and define each an inlet or outlet pipe 12 projecting relative to the inlet face 13 of the evaporator, that is to say the face through which the air flow F1 enters, and a interior volume divided by a partition 14 into a part 15 which communicates with the interior volumes of regions 5 of neighboring pockets and a part 16 which communicates with the interior volumes of regions 6 of these pockets.
- the refrigerant entering the evaporator through the inlet pipe 12 of the insert 10 is distributed, via of volume 15, between the interior volumes of regions 5 lying between one end 20 of the evaporator, located to the left of the figure, and a partition 17 formed by the bottoms of two bowls not provided with opening 9, these interior volumes forming a first collecting space 21.
- the fluid travels in parallel the elementary U-shaped paths delimited by the pockets that define it, the branches close to the face 13 and the branches close to the opposite face or face of outlet 18 forming respectively a first pass and a second pass, the latter leading to a second space collector 22 formed by the interior volumes of regions 6 of the same pockets which form the collecting space 21.
- the collector space 22 communicates through openings 9-1 with a third collector space 23, which is connected to its tower to a fourth collecting space 24, separated from the space 21 through partition 17, via elementary paths U-shaped forming a third pass and a fourth past.
- a transition insert 27 is interposed in the stack of sleeves, following the sleeves defining the collecting spaces 23 and 24.
- the insert 27 defines a unitary interior volume 28 extending over all the width of the evaporator, not communicating with the exterior thereof, separated from the space 23 by a wall 29 and communicating with space 24.
- volume 28 communicates with a collecting space 25 formed by the volumes interiors of regions 6 of the pockets to the right of insert 27 and up to the right end 30 of the evaporator, and is separated by a wall 31 of a collecting space 26 formed by the regions 5 of the same pockets.
- insert 27 passes the fluid from the fourth space collector 24, located in the row close to face 13, at fifth collector space 25, located in the next row from face 18, from where it arrives, via elementary U-shaped paths forming fifth and sixth passes, to the sixth collecting space 26, which communicates with the outlet pipe 12 via the volume 15 of the outlet insert 11.
- the refrigerant circulates twice in the opposite direction of the air according to the arrow F2, namely between the third and fourth passes and between the fifth and sixth passes, the traffic taking place in the same direction as air, according to arrow F1, only between the first two passes.
- This circuit improves the cooling capacity of the evaporator by compared to conventional circuitry in which the fluid refrigerant flows in the opposite direction of the air between the two first passes and between the last two passes, and in the same sense as this between the third and fourth passes.
- Figure 2 in which the solid line curve and dashed line curve represent the variation of the cooling capacity produced as a function of the air flow, respectively for a evaporator according to the invention and for an analogous evaporator with conventional circuitry.
- the total surface of the holes 32 is included between 3 and 10%, and preferably between 4 and 6%, of the surface of the openings 9 connecting two volumes together belonging to the same collecting space, or communicating between them two collecting spaces.
- the evaporator has been described above assuming that the head regions of the covers are located at the superior, it can also be oriented differently.
- the heat exchanger according to the invention may include more than one transition insert.
- the input insert and / or the output insert can be removed depending on the location of the tubes entry and exit.
- the number of passes may be different of six.
- the heat exchanger can exert another function as that of an air conditioning evaporator of vehicle, and can be produced using another technology than the stacked pockets.
