    Abstract: A liquid silicone resin composition as a gasket material comprising a base resin, a first crosslinking agent for causing a crosslinking reaction of the base resin, a silane coupling agent, a second crosslinking agent for forming a bond to the silane coupling agent, and a silica filler is used to form a gasket in a heat exchanger. Using this liquid silicone composition, the adhesiveness of the gasket can be enhanced while ensuring the sealing reliability of the gasket compared with conventional gaskets. Even when a resin which is difficult to adhere a silicon resin is used as a material of the tank body, the adhesive force of the gasket to the tank body can be sufficiently increased.

    Abstract: A variety of methods of forming polymer manifolds and the resulting manifold structures are described. The described manifolds are well suited for use in heat exchangers and a variety of other applications. In one aspect a polymer manifold includes a multiplicity of tubes having first ends that are received by a manifold housing. A polymer film is secured to the manifold housing and to the ends of each of the tubes. The film is arranged to seal the housing while leaving the openings of the tubes exposed to thereby create a manifold. In some embodiments, a potting material is used to reinforce the film. In a method aspect, a manifold may be formed by positioning first ends of the tubes in a manifold housing and welding a polymer film to the manifold housing and to distal tips of the tubes. Openings for the tubes are then formed in the film by directing heat towards the film which melts or vaporizes the film in the regions of the tube openings.

    Abstract: Disclosed is a heat exchanger comprising a boiling passage and cooling passage defined by opposite sides of metal walls. Layers of brazing material between the metal walls and a spacer member bond components of the heat exchanger together. It has been found that good quality brazed joints can be made by modifying the brazing thermal cycle to first employing a temperature of about 500° C. for an extended period of time and then elevating the temperature to about 590° to 600° C.
