Definitions
- the present invention relates to a heat exchanger for an air conditioning circuit of a motor vehicle, in particular to a connecting system between a radiating body of the heat exchanger and the inlet and outlet ducts of the air conditioning circuit.
- An air conditioning circuit of a vehicle comprises a compressor, a condenser, an expansion system, an evaporator and fluidic assembly for connecting the previously mentioned components to one another.
- the evaporator is crossed by an air current which is fed by means of specific ducts into the passenger compartment and the compressor may be arranged either in the front or in the back of the engine compartment.
- the compressor supplies work to take a fluid from a relatively low temperature and pressure, e.g. 2° C. and 2 bars respectively, to a higher pressure and temperature, e.g. 80° C. and 15 bars.
- the fluid gives heat to the outer environment in the condenser and is directed towards the evaporator, an expansion valve causing a pressure drop being interposed, until the fluid evaporates in the evaporator thus subtracting heat from the air flow which crosses it and which is conveyed into the passenger compartment.
- the compressor Downstream of the evaporator, the compressor should supply work to the fluid equal to the enthalpy difference between suction and delivery.
- the fluid aspirated by the compressor has a higher pressure and temperature, and the enthalpy difference and thus the work of the compressor decrease.
- the fluidic assembly ducts are arranged side by side along most of the path within the engine compartment and the exchanger has an elongated shape which follows the path of the ducts themselves.
- Heat exchangers comprising a main body for feeding both the refrigerating fluid to be heated and the heating fluid, and a pair of connectors mounted at respective ends of the main body for connecting the heat exchanger to the appropriate ducts of the air conditioning circuit.
- the main body defines a central duct and a plurality of peripheral ducts surrounding the central duct.
- the central duct is defined by a tubular wall.
- the peripheral ducts are defined in the radial direction by the tubular wall of the central duct and by an outer tubular wall which is concentrical to the tubular wall of the central duct and, in the circumferential direction, by a plurality of angularly equidistant rectilinear partitions (see FIG. 3 ).
- the central duct feeds the refrigerating fluid from the evaporator directed towards the compressor suction, and the peripheral ducts back-flow feed the refrigerating fluid exiting from the condenser.
- the main body is made by extrusion and may then be folded to adapt to the space available inside the engine compartment.
- a connector for a main body made by extrusion currently comprises a metal block defining a connecting port for one end from the main body, a port for the low-temperature refrigerating fluid and a port for the high-temperature refrigerating fluid.
- the main body For assembling the known connector, the main body should be machined by stock removing. Both the tubular wall and the partitions are removed along an axial end length. The tubular wall of the central duct is thus uncovered and inserted into the connector.
- the connecting port of the connector is shaped so as to fluidically connect the central duct to the low-temperature fluid port, and the peripheral ducts to the high-temperature, refrigerating fluid port.
- the object of the present invention is achieved by a heat exchanger according to claim 1 .
- FIG. 1 is a perspective view of a fluidic assembly which connects the main components of an air conditioning circuit to one another, and comprises an exchanger according to the present invention
- FIG. 2 is a partial axial section of a fitting of a tubular, concentrical heat exchanger according to the present invention
- FIG. 3 is a section taken along line in FIG. 2 ;
- FIG. 4 is a partial axial section of a second embodiment of the present invention.
- numeral 1 shows as a whole a fluidic assembly for an air conditioning system of a motor vehicle, comprising a high-pressure line 2 for feeding a refrigerating fluid between the delivery of a compressor and an expansion valve (not shown), and a low-pressure line 3 to feed a refrigerating fluid from the expansion valve to the compression suction (not shown).
- the high-pressure line 2 comprises metal and rubber ducts mounted in series, a fitting 4 adapted to be connected to the delivery of a compressor, a fitting 5 connected to the inlet of a condenser, and a tube 6 ′ between the fittings 4 and 5 .
- the high-pressure line 2 comprises a line 6 for connecting the condenser to an expansion valve (not shown).
- Line 6 comprises a fitting 7 adapted to be connected to the outlet of the condenser and a fitting 8 adapted to be connected to the expansion valve.
- the low-pressure line 3 comprises a line 9 having a fitting 10 adapted to be connected to the outlet of an evaporator (not shown) and a fitting 11 adapted to be connected to an inlet of the compressor.
- the ducts of lines 2 , 3 comprise at least one layer of a barrier material for preventing the normally very volatile refrigerating fluid from being permeated.
- a barrier material for preventing the normally very volatile refrigerating fluid from being permeated.
- the material may be aluminium or polyamide 6.10.
- the pipes are made of steel.
- the refrigerating fluid flowing in line 9 is at a low temperature and is heated by the refrigerating fluid flowing along line 6 to the condenser outlet.
- the fluidic assembly 1 comprises a heat exchanger 12 comprising a main body 13 and a pair of connectors 14 , 15 for fluidically and mechanically connecting the main body to the lines 6 and 9 .
- FIG. 2 shows a single end portion of the exchanger 12 , it being understood that the other end portion is identical to the one shown.
- the main body of the exchanger 12 comprises a tubular wall 16 having an axis A, an outer tubular wall 17 which is concentrical to the tubular wall 16 and a plurality of radial partitions 18 , all in a single body.
- the tubular wall 16 defines a duct 16 ′ belonging to the line 9 to feeding refrigerating fluid from the evaporator outlet to the compressor suction.
- the tubular wall 16 , the outer tubular wall 17 and the partitions 18 radially and circumferentially define, respectively, a plurality of ducts 18 ′ arranged parallel to one another and belonging to line 6 for feeding refrigerating fluid between the condenser outlet and the expansion valve.
- the main body 13 is made by extrusion.
- the connector 14 preferably comprises a tubular portion 19 defining a through duct 20 , a head 21 radially exiting from the tubular portion 19 and a sleeve 22 connected to a peripheral edge of the head 21 and surrounding the tubular portion 19 , all in a single body.
- portion 19 defines both an annular seat 23 for housing a pair of sealing rings 24 and corresponding spacer rings 25 and a shoulder 26 for defining the relative axial position of the connector 14 with respect to the main body 13 .
- the sealing rings 24 and the spacers 25 define a fluid-tight seal with an inner surface of the tubular wall 16 to avoid the refrigerating fluid from leaking from the high-pressure line 6 towards the low-pressure line 9 .
- the shoulder 26 is spaced apart from an inner surface of the head 21 and, when the connector 14 is mounted on the main body 13 , head 21 , a portion of sleeve 22 , a portion of the tubular wall axially comprised between the head 21 and a shoulder 26 and the main body 13 delimit an annular chamber 27 .
- the ducts 18 ′ lead into the annular chamber 27 which is connected to line 6 by means of a radial port 28 defined by the sleeve 22 .
- the sealing rings 24 define the fluidic seal on the inner surface of the tubular wall 16 and the sleeve 22 comes in contact with an outer surface of the outer tubular wall 17 .
- Sleeve 22 is rigidly fixed to the outer tubular wall 17 by means of an either low-temperature or cold connection, so as not to damage the sealing rings 24 which are already in a contact position with the inner surface of the tubular wall 16 when the fixing operation is to be performed, and may not be mounted at a later time.
- the fixing operation is performed by acting only on the outer tubular wall 17 and without acting on the tubular wall 16 , which substantially has the same length as the outer tubular wall 17 .
- the fixing operation is performed either by magnetically welding or crimping the lip of sleeve 22 or by means of a snapping connection with an elastic retaining ring and a seal, as shown in FIG. 4 .
- the aforesaid fixing methods may also be combined in series to improve the fitting tightness, e.g. by using a sealing adhesive and crimping the lip of sleeve 22 .
- the outer tubular wall 17 defines a seat 30 in which an elastic retaining ring 31 is housed.
- Sleeve 22 also has an annular seat facing the outer tubular wall 17 , within which both the elastic retaining ring 31 and a sealing ring 32 are housed to avoid the refrigerating fluid from leaking to the external environment.
- the connector 14 , 15 may be mounted on the main body 13 , 14 without stock removing operations on tubular wall 17 and partitions 18 .
- this result is achieved by the shape of the connector which fluid-sealingly surrounds the outer tubular wall 17 by means of sleeve 22 and internally comes in contact with the inner tubular wall 16 by means of the tubular portion 19 .
- no stock removing operations which completely remove the outer tubular wall 17 are carried out.
- Seats for elastic rings or sealing rings may be made instead.
- the main body 13 may be further connected to the lines 6 , 9 by minimum or null interventions on the main body 13 .
- the assembling operation is rapid and the fixing operation may be easily automated. Furthermore, if the main body 13 is made by extrusion, the excessively broad machining tolerances require a step of calibrating the outer tubular wall 17 before the connector 15 is mounted. This calibration may be carried out without cutting the tubular walls themselves and is generally performed by plastic deformation.
- the connector 14 , 15 may be entirely made by plastic deformation with great advantages in terms of times and costs.
- the connector 14 , 15 may be obtained in a single body by impact extrusion or by die-casting.
- the connector 14 , 15 may be adapted to many types of connection with line 9 .
- the connection may be of frontal seal washer type, as shown in the figures.
- the connector 14 , 15 may comprise, preferably in only one body, the male element of either a quick coupling or a threaded connection.
- a male element is coaxial to the axis A and protrudes with respect to the head 21 from the axial side opposite to the tubular portion 19 .
