Embodiment Construction
[0023] Will figure 1 The four heat exchange channel connections at one end of the shown regenerator communicate with the four heaters of the four working cavity Stirling heat engines respectively, and the four heat exchange channel connection ports at the other end communicate with the four radiators of the Stirling heat engine. The heaters and radiators of the same working chamber are connected to each other, and the heater and radiator of the same working chamber are connected to the two ends of the same heat exchange channel; the two working chambers of the four working chambers Stirling heat engine are opposite to each other, one is in the process of equal volume heat release, and the other It is in the process of isothermal heat absorption; one is in the process of isothermal expansion, and the other is in the process of isothermal compression; The flow direction in the device is opposite, and the two are connected to the adjacent heat exchange channel, and the working ch...

The invention provides a counter current heat-exchange type heat regenerator for a Stirling heat engine, which comprises a heat-exchange core, a heat-insulating layer, a pressure-bearing shell, an insulating layer and a plurality of connecting pipes arranged at two ends, wherein the heat-exchange core is arranged in the center of the heat regenerator; all heat-exchange walls of the heat-exchange core meet at a symmetric center by one edge, and meet the heat-insulating layer or the pressure-bearing shell by the other edge and two ends to form a plurality of heat-exchange channels which are centrosymmetric and have the same the structure; both ends of each heat-exchange channel are connected with a connecting pipe; and the pressure-bearing shell and the connecting pipes wrap the insulating layer externally. The counter current heat-exchange type heat regenerator has the advantages that: heat is recovered efficiently in a counter current heat-exchange mode by utilizing the characteristic that the flowing direction of working media in operating cavities in the heat release process is opposite to that of working media in operating cavities in the heat absorption process in the Stirling heat engine with the multiple operating cavities reasonably; and one counter current heat-exchange type heat regenerator can replace a plurality of heat accumulating type heat regenerators.
Description
Technical field [0001] The invention relates to a regenerator, in particular to a countercurrent heat exchange type regenerator. Background technique [0002] After the main structure of the Stirling heat engine is determined, the regenerator becomes a key component that affects the performance of the whole machine. The Stirling heat engine is developed from a single working chamber. According to traditional thinking, multiple working chambers are just a simple combination of a single working chamber. Influenced by this traditional design concept, the regenerative regenerator is still the only choice for modern Stirling heat engines, whether it is a single working chamber or multiple working chambers. [0003] A single working chamber Stirling heat engine can only use a regenerative regenerator. However, as long as there are more than two Stirling heat engines with multiple working chambers, either the regenerative regenerator or the counter-current heat exchange regenerat...
