Abstract

The invention relates to the technical field of regenerative heat engine equipment, and discloses a heat regenerator which comprises a wire mesh sleeve and a wire mesh column filled in the wire mesh sleeve. The wire mesh column comprises a first wire mesh assembly formed by stacking at least one layer of radial wire mesh in the radial direction of the wire mesh sleeve; and the mesh surface direction of the radial wire mesh is parallel to the axial direction of the wire mesh sleeve. The heat regenerator is simple in structure and convenient to manufacture, and the flowing direction of fluid in the heat regenerator is parallel to the mesh surface of the radial wire mesh, so that the heat exchange requirement can be met on the micro scale, and meanwhile, the flowing resistance can be remarkably reduced.

Description

technical field [0001] The invention relates to the technical field of regenerative heat engine equipment, in particular to a regenerator. Background technique [0002] The generalized regenerative heat engine is a kind of regenerator that uses working fluid to reciprocate through the regenerator, and releases heat to the heat storage medium for storage in one regenerating process. In another regenerating process, the stored heat will be used Quality recycling, this kind of cycle with heat storage and recovery process is called regenerative thermodynamic cycle. This heat storage component is called a regenerator. In thermoacoustic heat engines, Stirling heat engines, pulse tube refrigerators, VM refrigerators and other alternating flow heat engines, the regenerator is the key component for the conversion between heat energy and sound energy. Between low temperature heat exchange. When the engine absorbs heat energy to amplify the sound work, the heat exchanger at the high...
