Support assembly for finned tube type heat exchangers

A support assembly for attaching a heat exchanger to a frame of a machine, the heat exchanger having a tube member, the support assembly comprising:

• a clip having an inner perimeter that is configured to at least partially surround an outer perimeter of the tube member, the clip including a first end portion and a second end portion configured to engage the first end portion to hold the support assembly around the tube member in a closed position, the first end portion and the second end portion defining a seam line, and a lateral direction that is perpendicular to the seam line,
• wherein the first end portion includes a laterally-extending projection and a laterally facing surface spaced apart from the laterally-extending projection by a recessed area that, in combination with the first end portion, extends beyond the laterally facing surface in the lateral direction to form an undercut along a direction that is parallel to the seam line, the second end portion defines a recess configured to receive a portion of the laterally-extending projection such that the undercut is spaced away from the inner perimeter of the clip along the seam line, the laterally facing surface has a first width along the seam line and the recessed area has a second width along the seam line that is greater than the first width, the undercut remains empty after the first end portion is snapped into the second end portion, and the laterally facing surface of the first end portion contacts an engagement surface of the second end portion along the seam line and at a location that is closer to the inner perimeter of the clip than the laterally-extending projection of the first end portion.
