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.
  • EP2450657A1 discloses a heat exchanger according to the preamble of claim 1.
  • 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.

  • 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.
  • some elements or parameters may be indexed, such as a first element and a second element.
  • this indexation is only meant to differentiate and name elements which are similar but not identical. No idea of priority should be inferred from such indexation, as these terms may be switched without betraying the invention. Additionally, this indexation does not imply any order in mounting or use of the elements of the invention.
