  • Patent number: 11306981
    Abstract: A heat exchanger (1) includes a heat exchanging body (20) disposed within an outer box (10). A supply pipe (21) and a discharge pipe (22) in fluid communication with the heat exchanging body (20) respectively extend through first and second insertion holes (31, 32) in the outer box (10). Elastic seal members (40; 240) are respectively provided around the supply pipe (21) and the discharge pipe (22) and between a first sidewall (11) of the outer box (10) and the heat exchanging body (20). At least one biasing member (50; 250) exerts a lateral biasing force (F1; F2) on the elastic seal members (40; 240), thereby maintaining the elastic seal members (40; 240) in a state of compressive deformation and contacting the outer box (10) and the heat exchanging body (20) in an air-tight manner to block potential leakage paths (LP1; LP2) via the insertion holes (31, 32).

  • Patent number: 11131512
    Abstract: The exhaust duct includes an exhaust collecting portion connected a heat exchanger and an exhaust guiding portion communicating with the exhaust collecting portion and extended upward in a state close to a side of a cylindrical body of the heat exchanger. The exhaust collecting portion includes a connection opening constituting an inner peripheral wall, into which a cylindrical outlet side connection portion at the lower end of the heat exchanger is fitted, and a groove provided on an outer peripheral side than the inner peripheral wall of the connection opening. The packing includes a seal portion sandwiched in a compressed state between the inner peripheral wall of the connection opening in the exhaust collecting portion and an outer peripheral wall of the cylindrical outlet side connection portion in the heat exchanger to constitute a seal and an anchor portion inserted into the groove of the exhaust collecting portion.
