A MOUNTING ASSEMBLY FOR AN AUTOMOTIVE THERMAL SYSTEM
The present invention relates to 3 mounting assembly for an automotive thermal system, and In particular 3 mounting clip and bracket arrangement for mounting a heat exchanger or other component of an automotive thermal system component within an engine compartment in single longitudinal axis.
An automotive thermal system commonly comprises a heat exchanger, and a motor fan including a shroud and air guide to direct the airflow. These components are mounted within an engine compartment in a longitudinally stacked arrangement, with the components being arranged in a specific longitudinal order depending on the vehicle thermal system requirements.
The thermal system of a vehicle is located in the engine compartment of a vehicle, and Is typically disposed at the front of the compartment where the motor fan unit may be exposed to airflow through the front grill. The arrangement of components within an engine compartment Is designed to optimise the available space. Furthermore, there is an increasing trend for smaller, more economical cars. The size of the engine compartment in these smaller economical vehicles is greatly reduced and as such the space available for the thermal system is extremely limited. This limited space also presents problems during installation, as there is consequently very limited space to manoeuvre the heat exchanger as It is installed.
As shown in Figure 1, an automotive vehicle may be referenced in terms of three separate-axes. The first X-axis extends parallel to the longitudinal axis of the vehicle running lengthwise from the front to the back from the vehicle. A second Y-axis extends laterally across the vehicle orthogonal to the X-axis. The third Z-axis extends in the vertical direction orthogonal to both the X-axis and the Y-axis. In a larger vehicle the heat exchanger may be lowered vertically into the engine compartment, in the Z direction as well as being rotated fore and aft In the X direction during Installation If required. This allows the heat exchanger or other components of the thermal system to be inserted onto or into support structures extending In the 7 axis that vertically support the weight of the heat exchanger. However, in very small vehicles installation in the Z axis may be inhibited or prevented by the structure of the engine compartment, and in particular the front cross member. This is a particular problem where the vehicle requires more than one beat exchanger and/or a condenser. For example,, in small vehicles having a rear mounted engine with an intercooler, a secondary heat exchanger is required in the front engine compartment to provide cooling to the rear mounted intercooler. Therefore, the requirement to Install two heet exchangers as part of the thermal system further limits the available space. A new means of mounting an automotive thermal system where installation in the Z-axls is not possible that allows a secure flttmg while also minimising vibration and providing, thermal shock protection.
It is therefore desirable to provide an improved mounting assembly for an automotive beat exchanger or other component of an automotive thermal system which addresses the above described problems and/or which offers improvements generally.
According to the present invention there is provided a mounting assembly for an automotive beat exchanger or other component of an automotive thermal system as described In the accompanying claims. in an embodiment of the Invention there is provided a mounting assembly for an automotive heat exchanger or other component of an automotive thermal system having a vertical axis, a lateral axis, and a longitudinal axis which in use aligns with the longitudinal axis of the vehicle In it is mounted; the mounting assembly comprising; a first connector configured to be mounted at a first side of the component such that it extends away from the component in the longitudinal direction, and a corresponding first bracket configured to be mounted to a further structure within the vehicle and to receive the first connector in a longitudinal direction. The first connector and first bracket are configured such that when connected the first connector is restrained by the first bracket In the
Literal direction. The mounting assembly further comprises a second connector configured to he mounted at a laterally opposed second side of the component such that it extends away from the component in the same longitudinal direction 3s the first connector, and a corresponding second bracket configured to be mounted to a further structure within the vehicle and to receive the second connector in a longitudinal direction. The second connector and second bracket are configured such that when connected the second connector is restrained by the second bracket able to travel laterally relative to the first connector to accommodate thermal expansion of the component in the lateral axis. The further structure may be another thermal system component, or part of the engine compartment.
The term ’'restrained' means that any significant movement of the connector is prevented, but does not preclude spacing between the two components as a result of normal manufacturing tolerances and such that is required to permit free insertion of the connector into the bracket. This arrangement advantageously enables the component, which may be a heat exchanger or a motor fan shroud and airguide, to be mounted in the longitudinal 'x-axis' only.

This ensures that the component is both vertically and laterally anchored.
The mounting assembly may further comprise a third connector configured to be mounted at the first side of the automotive component at a vertically spaced location from the first connector such that it extends away from the component in the same longitudinal direction as the first connector, and a corresponding third bracket configured to be mounted to a further structure within the vehicle and to receive the third connectos in a longitudinal direction, the third connector and third bracket being configured such 3 that when connected the third connector Is restrained by the third bracket in the lateral direction and able to travel vertically relative to the first connector to accommodate thermal expansion of the component in the vertical axis.

Figure 16 shows a heat exchanger assembly according to anohior embodiment of the invention including a motor fan.
Referring to Figure 2, a heat exchanger 1 comprises a plurality of horizontally arranged parallel heat transfer tubes 2 interspaced and Interconnected by a plurality of corrugated fins 4, A pair of header tanks 6,8 are located at either end of the heat exchange tubes 2. The header tanks 6.8 are parallel and vertically arranged either side of the heat exchange tubes 2, and are connected to the tubes 2 via tube plates 10, The heat exchanger 1 is configured to be mounted within a vehicle with the heat exchange tubes 2 extending in the width-wise lateral Y-axis and the header tank 6.8 extending in the vertical Z-axis, with the front face 1.2 of the heat exchanger being arranged transversely to the longitudinal X-axls. However, It will be appreciated that the heat exchanger may be any other heat exchanger device such as a condenser or intercooler, and a heat exchanger assembly may include a combination of two or more of these heat exchange devices.
When viewed along the X axis from the rear of the heat exchanger 1, the first header tank 6 Is arranged on the left of the heat exchanger and the second header tank 8 is arranged on the right, it will be appreciated that the terms left, right, up, down, vertical and horizontal are relative terms relating to the arrangement of the apparatus in use and not attended to me limiting. The header tank 6 includes a pair of connectors 14 for securing the first header tank 6 to a further mounting component, within the engine compartment of the vetncie. This mounting component may be mounting brackets of the engine compartment or a further component such as a second heat exchanger or a condenser. The second header tank 8 also includes a pair of connectors 16 for connecting the second header tank 8 to a mounting component within the vehicle engine compartment to mount and support the heat exchanger 1. figure 3 shows the heat exchanger 1 from the rear side as part of a heat exchanger assembly, with the rear inner face 18 being foremost in the view shown. The connectors 14,16 extend perpendicularly from the rear face of the first header tank 6 and second header tank 8 respectively in the X direction. The connectors 14 of the first header tank 6 include a lower connector 20 and upper connector 22. The lower connector 20 and upper connector 22 are spaced from each other along the length of the header tank 6 such that they are vertically spaced in use. The lower connector 24 and upper connector 26 of the second header tank 8 are similarly spaced along the length of the second header tank 8 and are vertically spaced in use. The lower connector 20 of the first header tank 6 is vertically aligned with the lower connector 24 of the second header tank 8. The upper connector 22 of the first header tank 6 is vertically aligned with the upper connected 26 of the second header tank 8.
The lower connector 20 of the first header tank 6 is shown further detail in figure 4, The connector 2.0 includes a rigid body section 28 Including a horizontal lower wall 30 and a vertical side wall 34. A locking arm 36 is arranged parallel and spaced laterally from the side wail 34, and vertically spaced from the lower wail 30. The locking arm 36 comprises a flat, elongate section 37 connected at its proximal end to the body section 28 and extending from the rear of the body section 28 in a cantilevered manner, defining a male connection member, A locking head 38 is arranged at the free distal end of the locking arm 36. The Socking head 38 Includes a tapered wedge 40 that tapers outwardly away from the outer surface 42 of the main section 3? of the arm 28 and away from the side wall 34 along the longitudinal axis in a direction away from the distal end. The wedged section 40 terminates at a stepped section 44 defiling an abutment shoulder 44, The connector 20 is orientated such that when the header tank is vertically arranged the side wail 34 is vertically extending in the Z-axls with the lower wall 30 extending in the Y-axis and the locking arm 36 projecting in the X direction.
The connector 20 further includes a connector bracket section 46 for receiving a male connector arm 36 of a further connector. The bracket section 46 comprises an aperture configured to receive the side wall 34 and lower wall 30., and including a forward edge 47 to engage and retain the stepped shoulder 44 of the locking head 40. The bracket 46 is aligned with the locking arm 36 such that they share a common longitudinal axis. In this way, a locking arm received within the aperture 48 aligns with the longitudinal axis of the locking arm 20. As the connector 20 Includes both male and female connector parts that are longitudinally aligned, the connector 20 may be connected forwardly to a first further connector 20a, or be connected to rearwardlv by a further connector 20b, or both simultaneously. As such, components including connectors 20 may be selectively stacked in X direction and connected in any order, with this order being selectively interchangeable without requiring any modification to the connectors 20.
Figure 5 shows a view of the connector 20 along the Y axis. The connector 20 is received with in a corresponding bracket 46 of a further connector 20a. Alternatively the bracket 46 may be mounted independently to a further structure within the engine compartment. The bracket 46 includes a support surface 50 which receives and supports the lower wall 30 in the Z direction thereby vertically supporting and retaining the connector 20. The aperture 48 is configured to closely receive the connector 20 in the Z-axls with a minimal gap 52 being defined between the upper wall 30 and the upper edge 54 of the aperture 48. As such the connector 20 is vertically restrained within the bracket 46 with ilttie or no movement permitted in the Z-axis, It will be appreciated that while some movement may be possible on a small scale due to tolerance between the two parts, the fit is intended to substantially prevent movement in the Y and Z axis relative to the movement permitted by the other connectors as described below. The body section 28 only requires one o+ an upper or lower wail as one upper or lower wall is sufficient to laterally restrain the connector 20 in the Y direction, with only one side wail being required to restrain in the Z direction. The term 'restrain’ Is used to mean an arrangement in which substantially no movement is permitted in the relevant axis.
Figure 6 shows a view in the Z-axis of the connector 20 as part of a multi heat exchanger assembly, each of the heat exchangers having corresponding connectors. The aperture 48 of the bracket section of the f urther connector 20a, which Is the same configuration as the bracket section of the connector 20., is defined in the Y direction by side walls 56. I ac aperture 48 is configured to closely receive the connector 20 In the Y-axis with a minimal gap being defined between the side wail 34 and the side walls 56 of the aperture 48 4s such the connector 20 is laterally restrained within the bracket 46 with IIthe or no movement permitted in the Y-axis. With the connector 20 restrained in both the Z and Y axes by the connector 20, the connector 20 acts as the anchoring connector defining a non-moving registration point tor the heat exchanger 1.
As the connector 20 is inserted into the aperture 48 the tapered leading edge 40 of the locking arm 86 engages with the side wall 56 at the rear edge of the aperture 48, with the wedged engagement causing the locking arm 36 to flex laterally inwardly. As the connector 20 is further inserted the locking arm 36 continues to flex inwardly until the shoulder 44 passes through the aperture 48, at which point the arm 36 flexes outwardly to its original position, in this locked condition the abutment shoulder 44 prevents retraction of the connector 20 via engagement with the forward edge 47 of the aperture 48, The connector 20 may be removed from the bracket 50 via the application by user of a compressive force to flex the locking arm 36 inwardly until the abutment shoulder 44 has flexed Inwardly past the inner edge 56 edge of the aperture 48 and the connector 20 is able to be longitudinally retracted.
Referring again to Figure 5, a spring member 57 extends from the upper surface of the body section 28. The spring member 57 is a flexible arm connected to the body section 28 at its base. The arm 57 Is angled forwardly towards the distal end of the connector 20.
The distal tip 58 of the arm 57 is spaced inwardly along the length of the connector 20 from the locking head 36. As the connector 20 is inserted the arm 56 engages the outer surface of the bracket 50, Following engagement, as the connector 20 is further inserted the arm 57 begins to flex rearwardly applying a longitudinal returning force against the bracket 50, When the locking head 36 reaches the locked position and locks relative to the bracket 50 the arm 57 is held in a flexed condition. The flexed arm 57 applies a biasing force in the opposite longitudinal direction to the insertion direction urging the locking head 36 rearwardly against the inner surface of the bracket 50. In this way the locking head is held in a biased condition against the bracket 50 which prevents rattle in use.
The distance of the arm 57 along the connector 20 is selected such that the tip 58 is spaced rearwardly of the abutment shoulder 44 a distance less than the length of the aperture 48, with the base of the arm 57 being spaced rearwardly greater than this distance such that it is spaced from the bracket in the locked condition. A stop member 60 projects from the body section 28 having a forwardly facing abutment surface 62, The stop member 60 is positioned such that the abutment surface 62 is rearward of the tip 58, but forward of the base of the arm 36. The longitudinal spacing between the tip 58 and the abutment surface 62 of the stop member 60 represents a safe longitudinal flexing distance arm 56 over which the arm will not over-flex: or break, and such that the abutment surface 62 is spaced from the bracket 50 in normal use in the locked condition, in this way, the stop 60 protects the arm 56 by ensuring the connector 20 cannot be over Inserted Into the aperture 48 a distance that will cause over flexing of the arm 56.
Figure 7 shows the upper connector 22 of the first, side 6. The upper connector 22 is configured substantially the same as the lower connector 20, with a laterally flexing locking arm 64 having a locking head 66 that locks with the bracket in the same manner as described for the lower connector 20. As such, the locking mechanism for the upper connector 22 will not be described in detail here. The upper connector arrangement differs from the lower connector arrangement as shown in Figure 8, The bracket 68 of the further connector 22a in which the connector 22 is received includes an aperture 70 configured to receive the connector 22. The aperture 70 is configured to be received the connector 22 in the Z-axis with the height of the aperture 70 being greater than the height of the connector 22. As such a gap 72 is defined between the upper wali 74 of the connector and the upper edge 76 of the aperture 72, and a gap 78 is defined between the lower wail 80 of the connector and the tower edge 82 of the aperture 72 depending on the vertical position of the connector relative to the aperture 70. As such a lower tolerance exists between the connector 22 and the aperture 70 to accommodate any variation between the spacing of the apertures and the spacing of the connectors due to varying manufacturingtoierances, as well and enabling the connector to move vertically within aperture 72 to accommodate any thermal expansion of the header. The connector 22 also includes a spring arm 73 and a stop member 75 that operate in the same manner as described for the lower connector 20.
As shown in Figure 9 there Is substantially no gap defined between the connector 22 and the aperture 70 In the Y-axis, with the connector 22 being laterally restrained within the aperture 70 by the side wails 74 and lower wall 80, In this way, the upper 22 and lower 20 connectors prevent lateral movement in the Y axis of the first side 6 of the heat exchanger 1. As such the connector 22 is restrained in the Y direction and able to travel in the vertical 2 direction within the aperture 72. Vertical thermal expansion of the heat exchanger 1 causes an increase in the vertical spacing between the lower 20 and upper connectors 22. This expansion is accommodated by the ability of the upper connector 22 to slide vertically in the 2 axis within the aperture 72.
Figure TO shows the lower connector 24 of the second side 8 of the heat exchanger. The lower connector 24 Is vertically aligned with the first lower connector 20. The connector 24 comprises a main body 84 and a locking arm 86. The locking arm 86 is oriented such that the locking head 88 is vertically facing and is flexible in the vertical 2 axis. The main body Includes a lower wall 90 that is vertically aligned with the lower wall of the connector 7.0, and at least one vertical side wall 92. The bracket section 96 includes an aperture 98 for longitudinally receiving the connector 24 of a further connector. The connector 24 connects with the bracket 96 of a further connector in substantially the same manner as the lower connector 20, with the exception that the locking arm flexes vertically rather than laterally. As shown in Figure 11 the connector 24 includes a flexible spring arm 101 and a stop 103 which function in substantially the same manner as described for the lower connector 20,
The aperture 98 is configured to closely receive the connector 24 In the Z-axis with a minimal gap being defined between the upper and lower edges of the side walls 92 and the upper and lower edges 100 of the aperture 98, As such the connector 20 is vertically restrained within the bracket 96 with little or no movement permitted in the Z-axis. As shown in Figure 12. a lateral gap is defined between the sides 92 and the side edges 102 of the aperture 98. As such, the connector 24 is able to travel laterally In the Y-axis within the aperture 98. The connector 24 is therefore restrained in the X axis and able to move relative to the bracket 96 in the Y axis, in this way the connector 24 anchors the second side 8 vertically In the 2 axis while accommodating the varying Y-direction width of the heat exchanger during thermal expansion by moving laterally within the aperture 98 as the lateral spacing between the second lower connector 2.4 and first lower connector 20 varies;
Figure 13 shows the upper connector 26 of the second side 8 of the heat exchanger 1. The upper connector 26 comprises a pair of locking arms 106, The locking arms 106 are oriented such that the taper of the locking heads 108 face in outwardly opposing vertical directions defining an arrow head configuration. The locking arms 106 are vertically spaced and Inwardly flexible towards each other. The bracket section 110 comprises an aperture :112 for receiving the locking arms 106. The vertical height of the aperture 112 Is greater than the vertical distance between the upper surface 114 of the upper locking arm 196 and the lower surface 116 of the lower locking arm 106, and less than the vertical distance between the upper tip 119 of the upper locking head 118 defining the outer edge of the abutment shoulder 12.0 and the lower tip 122 of the lower locking head 124 defining the outer edge of the lower abutment shoulder 126. As such the height defined by the locking heads 106 in the unflexed state Is greater than height of the aperture 112. As the connector 26 is inserted into the aperture 112 of the bracket 11.9 the arms 106 flex inwardly as the locking heads 106 engage with the bracket 1.10 until the locking heads 196 pass through the aperture 112 and the arms return to the unflexed state with the 120,126 abutment shoulders prevent longitudinal retraction of the connector 26. As with the other connectors, the longitudinal axis of the male connector section 106 is aligned with the longitudinal axis of the bracket section 110,
As shown in Figure 14 the height of the aperture 112 is greater than the vertical distance between the upper surface 114 of the upper locking arm 106 and the lower surface 116 of the lower locking arm 106, when locked the connector 26 Is able to move vertically in the Z axis within the aperture 112. As shown in Figure 15 the aperture 1.12 is also wider in the V axis that the width of the arms 106, such that the connector Is also able to move within the aperture win the Y axis. As such, the connector is able to accommodate variance in the vertical spacing from the lower connector 24 due to vertical thermal expansion, as well as accommodate Literal thermal expansion in the V axis. The connector 26 includes a flexible spring arm 128 and a stop 130 which function in substantially the same manner as described for the lower connector 20.
The connectors 20, 22, 2.4 and 26 and are preferably integrally moulded as part of the respective header tanks, thereby advantageously obviating the requirement for securing separate connectors to the header tanks which may compromise sealing and add additional assembly. For other components such as a condenser, the connectors and brackets may be provide as separate components that are secured to the condenser independently. For example, moulded shoes may be provided which secure to a condenser, on which are integrally moulded the connectors and brackets. The brackets and/or connectors may alternatively be secured directly to the engine compartment, in the arrangement shown In Figure 16 the heat exchanger assembly 260 includes a motor fan 210,. In the arrangement of Figure 16 the motor fan 210 includes a plurality of brackets 212 corresponding to the connectors 214 of the adjacent heat exchanger 216.
The motor fan is arranged to be located longitudinally inwards of the further components of the assembly 200, and therefore does not include corresponding connectors for connection to a further inward heat exchanger component, in an alternative arrangement such additional connectors may be provided with motor fan include combined male and female connectors enabling it to be mounted at alternative longitudinal positions in the assembly. The brackets 212 are integrally moulded as part of the motor fan housing. Alternatively, separate shoes may be provided having integrally formed brackets which are mounted to the motor fan.
