Description
SPECIFICATION
Heat exchanger
This invention relates to heat exchangers, and particularly but not exclusively to automotive radiators used for cooling the water from the jacket of internal combustion engines.
Automotive radiators have been manufactured in the past by the assembly of a heat exchange core to a header plate and the subsequent fitting of a pressed metal or injection moulded plastics header tank to the header plate. Thus, in the case of each modei of radiator, special tooling is needed amongst other items to manufacture the header tank.
It is an object of the present invention to provide an improved construction of heat exchanger or radiator, in which the special tooling required for header tank manufacture is no longer required.
According to the invention, we provide a heat exchanger for automotive application comprising a heat exchange core extending between two header tanks, said core including tubes adapted to carry fluid to be cooled from one header tank to the other and a secondary heat exchange surface bonded to the exterior of said tubes, wherein each tank includes a rectangular header plate through which the tubes pass, said plate being secured at each of its longer edges to the longer edges of a substantially U or D-shaped tank section and at each of its shorter edges to a tank end member which is in turn secured to the tank section to close off the ends of the header tank. Both the header plate and the tank section are typically made of metal.
The tank end member may have an end face with integral portions which co-extend adjacent to the inner surface of the tank section and the header plate and which are spot welded or brazed to the header plate and to the tank section. The end face of the tank end member may be domed such that it provides a concave surface on its exterior.
The heat exchanger may include mounting members extending between respective shorter edges of opposed header plates. The mounting members may each comprise a channel shaped member opening outwardly away from the heat exchange core. The channel shaped member may have an integral tongue at each end which tongue is spot welded or brazed to the header plate. The tonque may be flat and bent through 900 adjacent the edge of the header plate, or alternatively the tongue may have a sinuous portion before being bent through 900. The tongue, the header plate and a co-extending portion of the tank end member may be spot-welded together in a single operation.
The longer edges of the tank section may each have an integral flange portion. The flange portion may be bent outwardly from the tank section and then towards the heat exchange core. The header plate may have a U-shaped trough portion adjacent each longer edge into which the flange portions of the tank section may be inserted. The walls of each said trough portion may be clinched together with the flange portion of the tank section between them in the fabrication of the heat exchanger. Alternatively, at least a portion of the outside walls of each said trough portion may be bent or clinched over the flange portion of the tank section to retain the tank section to the header plate. A fluid-tight joint between the longer sides of the tank section and the header plate may be provided by applying solder along the length of said joint.
Alternatively, the flange portion of the tank section may be bent away from the heat exchange core so that there is an acute angle formed between the wall of the tank section and the flange portion. With this construction the header plate may or may not have a trough portion adjacent each longer edge. Where it does have a trough portion the inner trough wall may extend parallel to and adjacent to the flange portion and the outer wall of the trough may extend beyond the flange portion and in use be clinched over the outside edge of the flange portion. In the absence of a trough portion, the header plate may extend beyond the perimeter of the flange portion which is inclined at an acute angle to the wall of the tank section, and the extension may in use be bent back over the flange portion and be clinched to it.
The tubes and the secondary heat exchange surface of the heat exchange core may be sufficiently precoated with solder material to enable them to be bonded together upon baking at a suitable temperature, the core being held together prior to baking by a pair of side members and a pair of clip members urging said side members towards one another, said side members and clip members remaining in position to form part of the heat exchanger. The mounting members preferably extend parallel to the side members and externally of them.
The tank sections may have bosses for entry and exit hose connections, and also filler protrusions and drain plug sockets. These various items may be bonded to the tank sections (with the necessary holes being made) either prior to the assembly of the tank sections to the header plates or they may be fitted later in the assembly process.
One embodiment of the invention will now be described, by way of example only, with reference to the accompanying drawings in which: Figure 1 is a perspective view of a heat exchanger according to the invention, being an automotive radiator for cooling the water from an internal combustion engine jacket;
Figure 2 is an end elevation of part of the radiator of Figure 1, shown in an intermediate stage of manufacture, and
Figure 3 is a side elevation in cross-section of part of the radiator of Figure 1, and
Figures 4 and 5 show details in end elevation of alternative constructions of the radiator of
Figure 1.
The radiator shown in Figure 1 comprises a heat exchange core 10 and an upper and a lower header tank, 11 and 12 respectively. The core 10 has several rows of copper tubes 13 which communicate at each end with the header tanks 11, 12. Secondary heat exchange surfaces in the form of copper corrugations 14 are bonded between each tube 13 (except at the end of the
row).
The header tanks 11, 12 each comprise a brass
header plate 15, a U-shaped tank section 16 and
tank end caps 17. The header plate 1 5 which
receives the ends of tubes 13 is rectangular in
shape and is formed with two U-shaped troughs
18, one adjacent each longer edge. The wall of
each trough 1 8 distant from the central region of
the header plate 1 5 extends upwardly and then
outwardly to form lip portions 19.
The tank section 1 6 has a flange portion 20
adjacent each of its longer edges, which flange
portion 20 is bent outwardly from the tank section 1 6 and then towards the heat exchange core 10
such that the termination of the flange portion 20
lies parallel to the wall of the tank section 16. The
dimensions of the flange portions 20 are such that
each one fits into one of the troughs 1 8 of the
header plate 15. The tank section 1 6 has a hose
connector boss 21 and the tank section 16
forming part of the upper header tank 11 has a
filler cap neck 22, both of which are typically
brazed on after suitable openings have been made
in the tank section 1 6.Each open end of the tank section 1 6 is closed off by an end cap 1 7 which is drawn from a sheet of brass, to provide an end face with portions which co-extend adjacent to the inner surface of the tank section 1 6 and the header plate 1 5 to enable the co-extending portions to be spot welded to the tank section 16 and the header plate 15, as seen in Figure 3.
A pair of mounting members 23 extend on opposite sides of the radiator between the header
plates 1 5. The mounting members are of steel and
are channel-shaped, opening away from the heat
exchange core 10, and are punched in the walls of
the channel to provide suitable holes for the
mounting of the radiator in its position in the
engine compartment of a vehicle. At the end of
each mounting member 23 an integral tongue 24
is bent through 900 so that it co-extends with and
adjacent to the end of the header plate 1 5 as seen
in Figure 3. A pair of brass or lead-coated mild
steel side members 25, which are either
castellated or channel-shaped when seen in crosssection, extend up the sides of the heat exchange
core 10 parallel to and within the mounting
members 23.A pair of clips 26 each in the form of
a length of steel rod bent through 900 adjacent each of its ends, pass along the top and the bottom of the heat exchange core 10 underneath the header plates 1 5 and between two rows of tubes 13 with their ends extending into the channels or between the castellations of the slide members 25 as seen in Figure 3.
The radiator is assembled from its component parts in the following manner. The heat exchange core 10 is assembled as one module using materials precoated with fluxed solder. The tubes 13 and corrugations 14 are assembled together with side members 25 and when complete, the clips 26 are pushed over the ends of each side member 25 to hold the assembly together whilst it is baked, thereby bonding the tubes 13 and corrugations 14 and the side members 25 together. The core 10 is assembled to its two header plates 1 5, such that the tubes 13 pass through punch holes in the header plates. The braze-coated header plates 15 are bonded to the tubes 13 in the region where the pre-soldered tubes 13 pass through each header plate 1 5 during the baking of the core.
Tank sections 16 are now assembled to the core 10 with its header plates 1 5 already attached. Bosses 21 and the filler cap neck 22 may have already been brazed on to the header tanks 11, 12 or they may be completed later in the process. The flange portions 20 on the side of each tank section 1 6 are urged into the troughs 18 on the header plate 1 5. A tool (not shown) is then applied to clinch at least portions of the walls of troughs 18 towards the flange portions 20 to hold the tank section 1 6 to the header plate 15, as seen in Figure 1 , the lip portions 19 of the header plate 15 being clinched over the flange portions 20 at each end of the tank section 16.The joints between the troughs 18 and the flange portions 20 are now sealed by brazing, the capillary action being sufficient to provide a good joint between the two components over the length of the header tank, the lip portions 1 9 which remain upright preventing spillage of braze material during the operation.
End caps 17 are applied to each open end of the header tanks 11, 12 and these are spot welded to the tank section 16. The two mounting members 23 are then positioned at each side of the radiator and the tongues 24 of the mounting members 2X, the header plate 15 and the portion of the end cap 1 7 which co-extends with the header plate 15, are spot welded together to finalise the assembly of the radiator. The end caps 17 are sealed to the header tanks by solder dipping or brazing.
Alternative arrangements for the joining of the tank section 16 to the header plate 1 5 are shown in Figures 4 and 5. In the embodiment shown in
Figure 4 the header plate 1 5 has trough portions 27 adjacent each of its longer edges. These troughs are not U-shaped as in the earlier embodiment, but commence with a right-angled wall extending towards the heat exchange core 23 and are then turned through an angle exceeding ninety degrees. The tank section 1 6 also has a flange portion 28 which differs from that of the first embodiment. From Figure 4 it will be seen that flange portion 28 coextends parallel to the right-angled wall of trough portion 27 and is then bent through an angle so that it is parallel to the other wall of the trough portion 27. Finally the trough portion 27 has an extension 29 which is bent back over the flange portion 28 and in use is clinched to the flange portion 28.
In the embodiment of Figure 5, the trough portions described in relation to the earlier embodiments are omitted. The flange portion 28 of the tank section 1 6 is constructed as described in relation to the embodiment of Figure 4 and the longer edges of the header plate 1 5 extend beyond the line of the wall tank section 16 and are then bent parallel to the flange portion 28. The header plate 1 5 has an extension 29 which is bent over the edge of the flange portion 28 and in use is clinched to the flange portion 28. The joints of the tank section 1 6 to the header plate 1 5 in both embodiments shown in Figures 4 and 5 are sealed by brazing or soldering the clinched joints.
