  • Tie bar clip construction for heat exchangers
    Patent number: 5404940
    Abstract: Increased resistance to deformation caused by internal pressure within a heat exchanger acting in a direction generally transverse to the length of tubes (18) extending between spaced headers (10,12) is achieved in a construction wherein side pieces (22) sandwiching the core defined by the tubes (18) and interposed fins (20) are coupled by means of tie bars (30) having transverse ends (32) embracing the side pieces (22). Resilient clips (40) act to secure the tie bars (30) to the side pieces (22) and include retention notches (54) to positively hold the clips (40) assembled to the structure.
