Definitions
- the present invention relates to a system for arresting movement of a body received within housing, particularly, the present invention relates to a system for arresting movement of a heat exchanger core received in a housing.
- a housing 2 as illustrated in FIG. 1 or a simple bracket 5 as illustrated in FIG. 2 is sufficient to arrest motion thereof in two directions, i.e. one parallel to the length and the other parallel to width of the heat exchanger core 4.
- the same bracket 5 or the housing 2 also arrests rotational motion of the heat exchanger core 4 in three rotational axes thereof.
- the housing 2 includes a first portion 2a and a second portion 2b that are disposed around a heat exchanger core 4 and the two portions 2a, 2b are held together.
- the bracket 5 also includes portions 5a and 5b that are disposed around the heat exchanger core 4 and joined at the ends 6a and 6b and the ends 6a and 6b are held together by fasteners to define an enclosure for receiving and securing holding the heat exchanger core 4 therein. Even in case some clearances are provided between the heat exchanger core 4 and the bracket 5 or the housing 2, these clearances can be removed by using the fasteners such as screws 3. Further, such an arrangement of fasteners or screws 3 also facilitates in enhancing grip of the bracket 5 or the housing 2 over the heat exchanger core 4 and also maintains the bracket 5 or the housing 2 in a gripping configuration thereof in which the bracket 5 or the housing 2 firmly grips the heat exchanger core 4 received therein.
- the simple bracket 5 or the housing 2 may fail to arrest the movement of the heat exchanger core 4 in a direction parallel to height of the heat exchanger core 4, particularly in the direction represented by arrows "Z" in the FIG. 1 and FIG. 2 .
- the bracket 5 or the housing 2 with heat exchanger cores 4 received therein are put into additional housings, they may be subject to various displacements therein. More specifically, as the heat exchanger core 4 along with the frame are not securely held inside the additional housing, the heat exchanger core 4 can move within the additional housing resulting in part to part contact between the internal walls of the additional housing and the outside walls of either the frame or the heat exchanger core 4 that in turn may cause noise. Also, such continuous part to part contact may cause damage to the heat exchanger.
- the heat exchanger core 4 is generally configured by stacking and joining a plurality of heat exchanger plates 4a, 4b, 4c... 4n by brazing. To ensure good brazing connection between the heat exchanger plates 4a, 4b, 4c... 4n, the height of the heat exchanger core 4 is not efficiently controlled. In some cases, compression forces applied and controlled by springs configured on brazing frames used during brazing. However, height of the heat exchanger core 4 is still not repeatable and may vary. Specifically, the heat exchanger cores 4 still exhibit height tolerances in the range of +/- 4 mm. Although, the tolerances can be reduced by process optimization, the process optimization is difficult to achieve.
- flexible clips 8a, 8b, 8c, ....8n are used for removing clearances that may occur to facilitate accommodating of different heights of the heat exchanger core 4 and arresting the movement of the heat exchanger core 4 in a direction parallel to height of the heat exchanger core 4, particularly in the direction represented by arrows "Z" in the FIGURE 1 and FIGURE 2 .
- such system may be prone to failure. More specifically, capacity of the clips 8a, 8b, 8c, ... . 8n to arrest movement of the heat exchanger core 4 in the "Z" direction is limited and such clips exhibit limited adaptability to even slight changes in heat exchanger core size, thereby failing to effectively arrest the movement of the heat exchanger core.
- the performance of the clips is dependent on the material properties of material configuring the clips 4 that may deteriorate with frequent use, wear and tear and exposure to stringent environmental conditions such as high temperature and vibrations to which the clips 8a, 8b, 8c, ....8n are often subjected to.

Description
- The present invention relates to a system for arresting movement of a body received within housing, particularly, the present invention relates to a system for arresting movement of a heat exchanger core received in a housing.
- Generally, length and width of a heat exchanger core is repeatable and a housing 2 as illustrated in
FIG. 1 or asimple bracket 5 as illustrated inFIG. 2 is sufficient to arrest motion thereof in two directions, i.e. one parallel to the length and the other parallel to width of theheat exchanger core 4. Thesame bracket 5 or the housing 2 also arrests rotational motion of theheat exchanger core 4 in three rotational axes thereof. The housing 2 includes afirst portion 2a and asecond portion 2b that are disposed around aheat exchanger core 4 and the twoportions bracket 5 also includesportions heat exchanger core 4 and joined at theends ends heat exchanger core 4 therein. Even in case some clearances are provided between theheat exchanger core 4 and thebracket 5 or the housing 2, these clearances can be removed by using the fasteners such asscrews 3. Further, such an arrangement of fasteners orscrews 3 also facilitates in enhancing grip of thebracket 5 or the housing 2 over theheat exchanger core 4 and also maintains thebracket 5 or the housing 2 in a gripping configuration thereof in which thebracket 5 or the housing 2 firmly grips theheat exchanger core 4 received therein. However, thesimple bracket 5 or the housing 2 may fail to arrest the movement of theheat exchanger core 4 in a direction parallel to height of theheat exchanger core 4, particularly in the direction represented by arrows "Z" in theFIG. 1 andFIG. 2 . Additionally, if such frames, particularly, thebracket 5 or the housing 2 withheat exchanger cores 4 received therein are put into additional housings, they may be subject to various displacements therein. More specifically, as theheat exchanger core 4 along with the frame are not securely held inside the additional housing, theheat exchanger core 4 can move within the additional housing resulting in part to part contact between the internal walls of the additional housing and the outside walls of either the frame or theheat exchanger core 4 that in turn may cause noise. Also, such continuous part to part contact may cause damage to the heat exchanger. - The
heat exchanger core 4 is generally configured by stacking and joining a plurality ofheat exchanger plates 4a, 4b, 4c... 4n by brazing. To ensure good brazing connection between theheat exchanger plates 4a, 4b, 4c... 4n, the height of theheat exchanger core 4 is not efficiently controlled. In some cases, compression forces applied and controlled by springs configured on brazing frames used during brazing. However, height of theheat exchanger core 4 is still not repeatable and may vary. Specifically, theheat exchanger cores 4 still exhibit height tolerances in the range of +/- 4 mm. Although, the tolerances can be reduced by process optimization, the process optimization is difficult to achieve. - Generally,
flexible clips heat exchanger core 4 and arresting the movement of theheat exchanger core 4 in a direction parallel to height of theheat exchanger core 4, particularly in the direction represented by arrows "Z" in theFIGURE 1 andFIGURE 2 . However, such system may be prone to failure. More specifically, capacity of theclips heat exchanger core 4 in the "Z" direction is limited and such clips exhibit limited adaptability to even slight changes in heat exchanger core size, thereby failing to effectively arrest the movement of the heat exchanger core. Further, the performance of the clips is dependent on the material properties of material configuring theclips 4 that may deteriorate with frequent use, wear and tear and exposure to stringent environmental conditions such as high temperature and vibrations to which theclips -
EP2450657A1 discloses a heat exchanger according to the preamble ofclaim 1. - Accordingly, there is a need for a system for arresting movement of a heat exchanger core with respect to the bracket or the housing, particularly, in a direction parallel to height of the heat exchanger core. Further, there is a need for a system for_arresting movement of a heat exchanger core with respect to the
bracket 5 of the housing 2 that obviates the drawbacks associated with use of clips that are conventionally used for arresting the movement of the heat exchanger core with respect to the housing, wherein such clips exhibit limited adaptability to change in heat exchanger core size and thereby fail to effectively grip and arrest movement of theheat exchanger core 4. Furthermore, there is a need for a system for arresting movement of aheat exchanger core 4 with respect to housing or the bracket that is not dependent on the material properties and performance thereof does not deteriorate with frequent use, wear and tear and exposure to stringent environmental conditions such as high temperature and vibrations. - An object of the present invention is to provide a system for arresting movement of a heat exchanger core received in a housing that tightly grips the heat exchanger core from all sides and effectively arrests any movement thereof.
- An object of the present invention is to provide a system for arresting movement of a heat exchanger core with respect to housing, particularly, in a direction parallel to height of the heat exchanger core.
- Yet another object of the present invention is to provide a system for arresting movement of a heat exchanger core whose performance does not deteriorate with frequent use, wear and tear and exposure to stringent environmental conditions such as high temperature and vibrations.
- In the present description, some elements or parameters may be indexed, such as a first element and a second element. In this case, unless stated otherwise, this indexation is only meant to differentiate and name elements which are similar but not identical.

Generally, the first shapedelements 36 are having a profile that is converging towards a base 30b of theinternal housing 30. Such a configuration of the first shapedelements 36 assists inserting of theinternal housing 30 inside the main housing but deters the removing of theinternal housing 30 from themain housing 10. Generally, the pressing arrangement includes first shapedelements 36 configured on an outer wall of thesecond portion 34 that interacts with an inner wall of themain housing 10 to press thesecond portion 34 against theheat exchanger core 20 when at least a pre-determined portion of theinternal housing 30 is received in themain housing 10. Alternatively, the pressing arrangement includes first shapedelements 16 configured on an inner wall of themain housing 10 that interacts with an outer wall of thesecond portion 34 to press thesecond portion 34 against theheat exchanger core 20 when at least a pre-determined portion of theinternal housing 30 is received in themain housing 10. However, the present invention is not limited to any particular configuration, number and placement of the first shapedelements elements second portion 34 against theheat exchanger core 20 when at least a pre-determined portion of theinternal housing 30 is received in themain housing 10. - In one embodiment of the present invention as illustrated in
FIG. 7b , the first shapedelements 16 formed on inner wall of themain housing 10 are received incomplimentary guide ways 39 configured on the outer wall of thesecond portion 34. Alternatively, as illustrated inFIG. 7c , the first shapedelements 36 formed on outer wall of thesecond portion 34 are received incomplimentary guide ways 19 configured on the inner wall of themain housing 10. Such a configuration facilitates guiding of theinternal housing 30 inside themain housing 10 while simultaneously pressing thesecond portion 34 inward towards theheat exchanger core 20 to define the pressing configuration of thesecond portion 34 and the gripping configuration of theinternal housing 30. Theguide ways 39 instead of being formed on the outside of thesecond portion 34 may be formed on the outside wall of theinternal housing 30 as illustrated inFIG. 7a , such that theguide ways 39 receive therein complementary elements configured on the inside wall of themain housing 10 to facilitate only guiding of theinternal housing 30 inside themain housing 10. However, the present invention is not limited to any particular configuration, number and placement of theguide ways guide ways elements internal housing 30 inside themain housing 10. - In one embodiment of the present invention, the
main housing 10 includes atop cover 10a and abottom portion 10b. Thetop cover 10a is releasably attached to thebottom portion 10b.

However, the present invention is not limited to any particular configuration of engaging elements configured on thetop cover 10a and thebottom portion 10b as long as the engagement elements configure releasable attachment of thetop cover 10a to thebottom portion 10b. - The
system 100 further includes a retaining arrangement configured between theinternal housing 30 and themain housing 10. The retaining arrangement retains theinternal housing 30 within themain housing 10, thereby causing thesecond portion 34 to be pressed inwards by the first shapedelements second portion 34 in the pressing configuration thereof and theinternal housing 30 in the gripping configuration thereof. Particularly, the retaining arrangement includes second shapedelements 18 configured on at least one of thetop cover 10a and thebottom portion 10b. The second shapedelements 18 extend from thetop cover 10a and interact with the thinner parts of thesecond portions 34 to further press thesecond portions 34 against theheat exchanger core 20 received therein when at least a pre-determined portion of theinternal housing 30 is received in themain housing 10 and thetop cover 10a is mounted on thebottom portion 10b. With such configuration, thinner parts of thesecond portions 34 that extend beyond the periphery of theinternal housing 30, more specifically, the parts of thesecond portions 34 that extend beyond thefirst portion 32 are further pressed against theheat exchanger core 20 to enable theinternal housing 30 to further grip theheat exchanger core 20. In the assembled configuration of thetop cover 10a on thebottom portion 10b, the thinner parts ofsecond portions 34 are pressed by the second shapedelements 18, the thinner parts of thesecond portion 34 also exert reaction forces on the second shapedelements 18 to push thetop cover 10a upwards. Accordingly, the clearances that occur between the clips and thehousing 10 to facilitate accommodation of different heights of theheat exchanger core 20 are eliminated, when thetop cover 10a is assembled to thebottom portion 10b of thehousing 10. Further, the retaining arrangement allows to mitigate play between the cover and the bottom portion. - In one example, the first shaped
elements shaped elements 18 to retain at least the pre determined portion of theinternal housing 30 within themain housing 10, thereby causing pressing of the second portion inwards towards theheat exchanger core 20 and maintaining thesecond portion 34 in the pressing configuration thereof and theinternal housing 30 in the gripping configuration thereof. In accordance with an embodiment of the present invention illustrated inFIG. 9 , the second shapedelement 18 engages withcomplimentary latching element 38 configured on outside wall of theinternal housing 30 to retain at least the pre determined portion of theinternal housing 30 within themain housing 10, thereby causing the first shapedelement 16 to press thesecond portion 34 inwards toward the andheat exchanger core 20 and maintaining thesecond portion 34 in the pressing configuration thereof andinternal housing 30 in the gripping configuration thereof. - Several modifications and improvement might be applied by the person skilled in the art to the system for arresting movement of a heat exchanger core as defined above, as long as the system comprises a main housing, an internal housing and a pressing arrangement. The internal housing is located in the main housing and receives the heat exchanger core. The internal housing includes a first portion and a second portion.
