Description

Heat Exchanger Core
The present invention relates to a heat exchanger core. The present invention also relates to a working machine including a heat exchanger core and a method of mounting an attachment on a heat exchanger core.
It is known to mount spinning blades on the heat exchanger units of combine harvesters to aid the cleaning of the face of the heat exchanger core and to prevent debris clogging the heat exchanger core. Such blades can be actively propelled or spin passively in order to sweep away airborne chaff and contaminants.
At present, such sweeper units are mounted directly through a fin section of the heat exchanger core. The mounting fixture is passed through a break that is inserted in the fin.
This is disadvantageous as fin sections require a stop to hold the fin in place within the heat exchanger core, the heat exchanger core may require local reinforcement around the fin gap to prevent a weak point where there is a lack of fin material and the axle or bolt of the mounting fixture needs sufficient space to pass through with clearance.
According to a first aspect of the invention there is provided a heat exchanger core comprising layers of fin stock between passageway means defining passageways for heat exchange fluid, the core including at least one member including a continuous wall defining a through bore, the member being provided between two passageway means layers, the bore defining an opening through the heat exchanger core from one side to the other, the bore being arranged to receive an axle or a bolt.
The at least one member of the heat exchanger provides a mounting for an attachment, for example a spinning blade. The at least one member facilitates the build-up of the heat exchanger core, providing a physical break between two or more pieces in the fin stock layer and holding the gap during the braze process to ensure that the pass-through remains consistent.
The at least one member further provides the reinforcement necessary for the heat exchanger core, eliminating the weak spot that can arise when the heat exchanger core is pressurised from a gap in the fin stock.
The at least one member also provides a safe and reliable method of allowing the pass-through of a bolt or axle for the affixing of further mechanisms or mountings to the heat exchanger core, protecting the heat exchanger core from damage which could be caused by insertion or removal of these devices. The at least one member also aids in the location of these devices during fitting.
The bore may extend along a longitudinal axis of the member. The bore may have a curved inner surface, for example a cylindrical inner surface. The curved inner surface may be arranged such that an axle or a bolt can be fixed in the bore, for example the curved inner surface may include a threaded portion for fixing an axle or a bolt in the bore.
The at least one member may be in the general form of a rectangular block.
The at least one member may include at least one locating projection which extends from an outer wall of the member in the direction of the fin stock. The at least one locating projection may extend along the longitudinal axis of the bore. The at least one locating projection may be a rib. The at least one locating projection may taper away from the outer wall of the at least one member.
The outer wall may be a first outer wall and the at least one locating projection may include a first locating projection extending from the first outer wall, the at least one member may further include a second locating projection, the second locating projection extending from a second outer wall of the at least one member. The first outer wall may be opposite to the second outer wall.
The heat exchanger core may have a depth and the at least one member may have a length, wherein the length of the at least one member may be substantially equal to the depth of the heat exchanger core. The length of the at least one member may be equal to the depth of the heat exchanger core.
The fin stock layer may have a height and the at least one member may have a height, wherein the height of the at least one member may be substantially equal to the height of the fin stock layer. The height of the at least one member may be equal to the height of the fin stock layer.
The at least one member may be brazed to the heat exchanger core. The at least one member may be brazed to two passageway means layers.
The at least one member may be spaced from the sides of the heat exchanger core.
The heat exchanger core may include a plurality of members. The plurality of members may be aligned along a horizontal axis of the heat exchanger core. The plurality of members may be aligned along a vertical axis of the heat exchanger core.
A plurality of members may be mounted within the heat exchanger core for flexibility in mounting arrangements, with placement being at any point within the external fin areas of the heat exchanger.
The heat exchanger core may be a heat exchanger core for any one of a radiator, a charge air cooler and an oil cooler.
The heat exchanger core may further include an attachment, wherein the attachment is mounted to the at least one member, for example by an axle or a bolt.
The attachment may be a blade, for example a spinning blade.
According to another aspect of the invention there is provided a working machine including a chassis, ground engaging motive means, an engine and a heat exchanger core according to the first aspect of the invention. The working machine may be a combine harvester.
According to a further aspect of the invention there is provided a method of mounting an attachment on a heat exchanger core, the method including the steps of:
a. assembling a heat exchanger core according to the first aspect of the invention in a core building jig,
b. mounting at least one member within the heat exchanger core in the jig,
c. brazing the heat exchanger core including the at least one member, and

With reference to Figures 1 to 4, there is shown a heat exchanger core 10 according to a first embodiment of the invention. The heat exchanger core 10 includes a plurality of passageway means layers 12b, 12c, 12d, 12e, 12f, 12g, 12h, 12i, 12j, 12k a plurality of fin stock layers 14a, 14b, 14c, 14d, 14e, 14f, 14g, 14h, 14i, 14j, 14k, a pair of spacer bars 15a, 15b and a mounting member 16.
Each of the passageway means layers 12b, 12c, 12d, 12e, 12f, 12g, 12h, 12i, 12j, 12k is an aluminium plate having a passageway (not shown) for a heat exchange fluid (not shown).
Each of the fin stock layers 14a, 14b, 14c, 14d, 14f, 14g, 14h, 14i, 14j, 14k is a sheet of corrugated aluminium. Fin stock layer 14e includes two fin stock layer sections 14ea, 14eb.
Referring now to Figures 8 and 9, the mounting member 16 is an aluminium spacer bar having an elongate body 18. The elongate body 18 has a first end 20, a second end 22, a length L, a height h and a width w. The elongate body 18 is generally rectangular and has an upper wall 24, a lower wall 26, a first side wall 28, a second side wall 30, a first end face 32 and a second end face (not shown).
The elongate body 18 has a longitudinal axis A-A and a through bore 34 that extends from the first end face 32 to the second end face (not shown) along the longitudinal axis A-A.
The through bore 34 has a diameter d and a cylindrical inner surface 36.
The mounting member 16 includes a first locating projection 38 in the form of a rib that extends along the length of the first side wall 28 and tapers away from the first side wall 28. The first locating projection 38 has an outer tip 40 that extends outward from the first side wall 28 in a direction that is away from the through bore 34.
The mounting member 16 also includes a second locating projection 42 in the form of a rib that extends along the length of the second side wall 30 and tapers away from the second side wall 30. The second locating projection 42 has an outer tip 44 that extends outward from the second side wall 30 in a direction that is away from the through bore 34.
The heat exchanger core 10 is assembled in a core building jig with alternating layers of passageway means layers 12b, 12c, 12d, 12e, 12f, 12g, 12h, 12i, 12j, 12k and fin stock layers 14a, 14b, 14c, 14d, 14e, 14f, 14g, 14h, 14i, 14j, 14k arranged between a lowermost passageway means layer (not shown) and an uppermost passageway means layer (not shown). Fin stock layer 14e is arranged such that a gap 15 is formed between the two fin stock layer sections 14ea, 14eb away from the outer edges of the heat exchanger core 10.
The mounting member 16 is inserted into the gap 15 between fin stock layer sections 14ea, 14eb. The length L of the mounting member 16 is the same as the depth of the heat exchanger core 10 such that the mounting member extends the entire depth of the heat exchanger core 10. The height h of the mounting member 16 is the same as the height of the fin stock layers 14a, 14b, 14c, 14d, 14e, 14f, 14g, 14h, 14i, 14j, 14k and thus the upper wall 24 of the elongate body 18 is positioned adjacent to a lower surface (not shown) of the passageway means layer 12d and the lower wall 26 of the elongate body 18 is positioned adjacent to an upper surface (not shown) of the passageway means layer 12e.
The components of the heat exchanger core 10 are joined by brazing, the upper wall 24 of the elongate body 18 being brazed to the lower surface (not shown) of the passageway means layer 12d and the lower wall 26 of the elongate body 18 being brazed to the upper surface (not shown) of the passageway means layer 12e. In this way, the mounting member 16 is an integral part of the heat exchanger core 10.
The width of the gap 15 is such that the mounting member 16 is spaced apart from the fin stock layer sections 14ea, 14eb, i.e. the outer tip 40 of the first locating projection 38 is adjacent to the fin stock layer section 14ea and the outer tip 44 of the second locating projection 42 is adjacent to the fin stock layer section 14eb. In this way, the mounting member applies pressure to the fin and compression to the length, facilitating the location of the fin stock layer sections 14ea, 14eb and to aid in maintaining their position during the braze process.
The heat exchanger 10 can then be assembled into any known type of heat exchanger, for example a radiator, a charge air cooler or oil cooler.
In use, an axle 50 (as shown in Figure 2) for an attachment, for example a spinning blade 52 as shown in Figures 1 and 2 may be inserted into and fixed within the through bore 34. The spinning blade 52 can then be mounted onto the axle 50.
In some embodiments of the invention the inner surface 36 of the through bore 34 may include a threaded portion 54 as shown in Figure 12 to facilitate fixing of the axle 50 within the through bore 34.
In the embodiment described above, the heat exchanger core 10 is a plate and fin type. It will be understood that the mounting member 16 could be used in other heat exchanger core arrangements, for example bar and plate, plate and spacer bar, tube type or plate type.
In the embodiment described above, the mounting member 16 includes two locating projections. It will be understood that in alternative embodiments, the mounting member may include one locating projection that extends from one side wall of the elongate body.
