Heat exchanger assembly having a distributor tube retainer tab

A heat exchanger assembly (20) having an insertable distributor tube retainer tab (100) configured to position and retain a distributor tube (40) disposed within a first manifold (22) extending along an axis A manifold . The first manifold (22) includes a manifold wall (23) having an interior surface (26) defining an interior chamber (27), an exterior surface (29) opposite of the interior surface (26), and a retainer slot (42) connecting the interior surface (26) and the exterior surface (29). The retainer slot (42) extends substantially transverse to the manifold (22) axis A manifold. The retainer tab (100) is inserted through the retainer slot (42) and includes a first tab portion (102) disposed within the interior chamber (27) and a second tab portion (104) engaged to the wall (23) of the first manifold (22), and may also include a third tab portion (106) engaged to a width surface (46) of the retainer slot (42). The retainer tab (100) includes a tab opening (101) configured to engage and maintain the distributor tube (40) within the predetermined position.
