An automotive heat exchanger that includes a manifold (12) and a mounting block (10) attached to the manifold (12) and over an opening (30) in the wall of the manifold (12). The mounting block (10) has a flange portion (16) with a surface (18) that engages approximately half of the outer perimeter of the manifold (12). The block (10) also includes means (20, 24) for securing the heat exchanger to an automobile (14), and an inlet/outlet port (26) extending through the block (10) and in fluidic communication with the opening (30) in the wall of the manifold (12). Grooves (19) are preferably present in the surface (18) of the flange portion (16) of the block (10), two of which engage raised portions (23) on the perimeter of the manifold (12) in order to aid in securing the block (10) to the manifold (12). The remaining grooves (19) provide reservoirs between the block (10) and manifold (12) for braze material (21) that metallurgically bonds the block (10) to the manifold (12). A sleeve (28) is preferably disposed partially within the inlet/outlet port (26) and partially within the opening (30) in the manifold (12), so as to provide a leak-free joint between the block (10) and manifold (12). |
