专利汇可以提供Heat exchangers for stirling cycle engines专利检索,专利查询,专利分析的服务。并且A structural arrangement for a heat exchanger provides for movements without significant stresses of a heat exchanger in a Stirling Cycle Engine during changes of operating temperature. Two coaxial shell sections are arranged with a plurality of parallel heat exchange pipes axially mounted therebetween and affixed to the two sections. A flexible sealing element is sandwiched between the two shell sections to allow movement of the shell sections perpendicular to the axes of the heat exchange, pipes. A spacer separating the heat exchange pipes in the middle allow the pipes to bow as unit with evenly distributed deformation during temperature changes. Fluid conveyance pipes are connected to each shell section at the opposite ends of the heat exchange pipes.,下面是Heat exchangers for stirling cycle engines专利的具体信息内容。

1. A tubular heat exchanger of the kind used as a cooler in a hot gas engine for conveying gases from a plurality of heated pipes to a gas duct connected with a compression working space of a hot gas engine, comprising in combination two generally cylindrical and co-axial shell sections each having end covers, a plurality of heat exchange pipes for carrying working gas extending axially within the shell sections and rigidly connected at opposite ends to said end covers, inlet and outlet passages for conveying cooling fluid into said cylindrical shell sections to contact said pipes, and a sealing element held between said sections allowing movements between said sections in directions substantIally perpendicular to the axes of the shell sections.
2. A heat exchanger according to claim 1, characterized in that said two shell sections are of substantially equal axial length.
3. A heat exchanger as defined in claim 1 wherein said inlet and outlet passages for conveying said cooling fluid are respectively connected to different ones of said two shell sections.
