Embodiment Construction

[0025] figure 1 The Stirling heat engine annular heat exchanger shown can be used as a heater and cooler for a Stirling reversible heat engine. As a heater, it is arranged in the middle of the four cylinders at the heat inflow end, the symmetrical center line coincides with the rotor axis of the heat engine, and the outer side is in contact with the cylinder surface. The four connecting pipes at one end of the heater communicate with the four cylinders at the heat inflow end respectively, and the four connecting pipes at the other end communicate with the four connecting pipes at one end of the regenerator respectively. As a cooler, it is arranged in the middle of the four cylinders at the heat outflow end, and the outside is in contact with the cylinder surface. The centerline of symmetry coincides with the axis of the rotor of the heat engine, and the rotor axis of the heat engine just passes through the central channel of the heat exchanger and is connected with the shaft ...

Abstract

The invention provides a ring heat exchanger of a sterling heat engine. The ring heat exchanger comprises a ring heat exchanger main body and a plurality of connecting pipes which are arranged at two ends of the ring heat exchanger main body. The interior of the ring heat exchanger is provided with at least two heat exchange channels in a centrosymmetrical distribution manner, and the symmetrical center is the center of the central channel; two ends of each heat exchange channel are respectively provided with a connecting pipe; a heat exchange wall between the heat exchange channels is internally provided with a plurality of heat exchange holes; and heat exchange plates are distributed on the surface of the ring heat exchanger. The ring heat exchanger of the sterling heat engine provided by the invention has the advantages that a plurality of working chambers of each individual heat exchanger of the sterling heat engine are integrated into a whole, and the heat exchanging demands of the working chambers at each thermodynamic process are satisfied; the heat exchange area between the heat exchanger and a heat source is increased effectively, the heat exchange capability is strengthened, and the existing water cooling system can be completely replaced by a wind cooling system; the ring heat exchanger is especially used for a sterling invertible heat engine, the space is utilized fully, and the volume of the whole ring heat exchanger is smaller.

Description

Technical field [0001] The invention relates to a heat exchanger, in particular to an annular heat exchanger of a Stirling heat engine. Background technique [0002] The heat exchanger is an important part of the Stirling heat engine, which is required for heating, cooling, and heat recovery. At present, tube heat exchangers or fin heat exchangers are generally used for heating of Stirling heat engines; water-cooled heat exchangers are mainly used for cooling; regenerative heat exchangers are used for heat recovery. Comprehensively balancing the contradiction between the flow volume of the heat exchanger, the flow resistance loss of the working fluid, and the heat exchange capacity is the principle that all types of heat exchangers must follow. [0003] The branch-tube heater of the existing Stirling heat engine is multi-tube parallel, the same flow volume is smaller than the flow resistance of the full-tube heater, and the heat exchange capacity is enhanced. At the same ti...
