Definitions
- the present invention relates to a heat exchanger.
- It relates more specifically to a heat exchanger comprising at least one tube and a collector, said collector being provided with at least one receiving bore of the end of the tube.
- tube is meant here an elongate dish-shaped element comprising at least one longitudinal channel, generally several longitudinal channels juxtaposed over the width of the strip.
- each tube is provided at its ends with two deformations ensuring the formation of abutment shoulders against the outer face of the collectors, when it is inserted and fixed in the corresponding bore of the collector.
- Such an arrangement requires the machining of bores and tubes with very precise ribs, in order to ensure tight communication of the longitudinal channel or channels of the tubes and of the longitudinal channel or channels of a collector and especially to avoid deformation of the longitudinal channels of the tubes, once the latter placed in the bores of the collector.
- the invention solves this problem by proposing a heat exchanger whose collector is preferably made by extrusion or by machining and eliminating the need for making these shoulders on the tubes.
- the invention proposes a heat exchanger comprising at least one tube and a collector, said collector being provided with at least one receiving bore of the end of the tube characterized in that said receiving bore comprises at least one abutment portion of the corresponding end of said tube.
- said abutment portion is disposed at a lateral end in said collector receiving bore.
- said abutment portion comprises at least one rib disposed laterally in the receiving bore of the collector.
- said collector comprises at least two longitudinal channels disposed near the longitudinal edges of the collector, a said rib being disposed each time in a said longitudinal channel of the collector disposed near the longitudinal edges of the collector.
- said manifold comprises a transverse flow channel connected to at least one transverse connecting channel transverse to said flow channel and opening into said receiving bores, and said abutment portion is in upper part and / or lower in said bores of the collector.
- Two said tubes can be received in each said receiving bore.
- Said collector may be composed of at least two parts, namely a so-called collecting plate part comprising at least one receiving bore of at least one end of a tube and a so-called collecting box comprising longitudinal channels.
- Said collector may be metal, preferably aluminum.
- said abutment portion is preferably obtained by said extrusion.
- Said collector can be made by extrusion along its transverse axis.
- FIG. 1 is a perspective view of a portion of a heat exchanger according to a first embodiment.
- FIG. 2 is a sectional view of a heat exchanger according to this first embodiment, along an X, Y plane.
- FIG. 3 is a sectional view of a portion of a heat exchanger according to a second embodiment, along an X, Z plane.
- FIGS. 4 and 5 are sectional detail views of a heat exchanger according to two variants of this second embodiment, along an X, Z plane.
- Figures 1 and 2 show a first embodiment of the invention.
- a heat exchanger comprises a plurality of tubes 1, comprising at least one longitudinal channel, and preferably a plurality of longitudinal channels juxtaposed along their width along the Y axis, and connected at their ends to a collector 2 comprising at least one longitudinal channel flow of a fluid, here more precisely four longitudinal channels 2A juxtaposed on the Y axis and each directed along the Z axis.
- the collector 2 is composed of at least two parts, namely a so-called collecting plate part 20 comprising at least one bore 2B serving to receive at least one end of a tube 1 and a part said header box 21 having longitudinal channels 2A.
- the subjection between the two parts of the collector may be effected, for example, by brazing.
- means for receiving the header plate on the manifold may, for example, take the form of a groove in which will be inserted said collector plate.
- the exchanger comprises at least one manifold 2 and is provided with at least one receiving bore 2B of one end
- the tubes 1 are in fluid communication with the channels 2A of the manifolds via the receiving bores provided here on the header plate 20 of the manifold.
- the tubes are arranged in pairs 1A, 1B in each bore.
- the tubes are of corrugated shape.
- the fluid enters the exchanger by a first so-called feed collector and runs through the channels 2A of this collector. Thereafter, this fluid will circulate in the tubes 1, then will be evacuated by a second so-called evacuation collector.
- Each collector 2 is made of metal, preferably aluminum, and can be made by extrusion or by machining, along the Z axis.
- At least one bore 2B of the collector 2 has a stop portion for the corresponding end of each tube 2.
- This stop may, for example, be obtained by extrusion or by machining.
- the end of the tube 1 is formed of a straight cut, that is at right angle, which abuts against this shaped abutment portion of at least one here two ribs 2C, 2D arranged laterally in the bore 2B of the collector 2.
- These ribs 2C, 2D are here arranged in the two longitudinal end channels 2A1, 2A2 arranged near the longitudinal edges of the collector 2.
- Figures 3 to 5 show a second embodiment of the invention.
- a heat exchanger comprises a plurality of superimposed tubes, comprising at least one longitudinal channel, and preferably a plurality of longitudinal channels juxtaposed along their width along the Y axis.
- the ends of the tubes are inserted into a collector 2 ' including the bores said reception 2'B.
- the collector 2 ' comprises a channel 2 ⁇ for flowing a fluid, this channel 2 d'flow of the manifold being transverse and connected, here, to a plurality of connecting channels 2 ⁇ transverse to said flow channel 2 ⁇ and opening into bores 2'B receiving each end of the tubes.
- the exchanger comprises, here, two collectors 2 'and the longitudinal channels of the tubes and the channels 2 ⁇ , 2 ⁇ collectors are in fluid communication.
- the tubes are in fact arranged in pairs A, B in each bore and are here also of corrugated shape.
- the fluid enters the exchanger through a first collector said supply and runs through the transverse channels 2 ⁇ of this collector. Subsequently, this fluid will circulate in the tubes, then will be evacuated by a second collector called evacuation.
- Each collector 2 ' is made of metal, preferably aluminum, and is made by extrusion along its transverse axis along the Y axis.
- At least one bore 2'B comprises at least one abutment portion of the corresponding end of the tube 1 ', advantageously obtained by this extrusion.
- the end of the tubel ' is formed of a straight cut, that is to say at right angle, which abuts against this shaped abutment portion of a rib 2'C arranged in the upper part in each bore 2'B of the collector.
- the end of the tube is formed of a straight cut, that is to say at right angle, which abuts against this shaped abutment portion.
- a rib 2'C disposed in the upper part and a second rib 2'D arranged in the lower part in each bore 2'B of the collector.
- the abutment portion may also be shaped only of a rib disposed at the bottom in each receiving bore 2'B of the collector.
