1. A thermoelastic energy converter (1), being used in a thermoelastic heating/cooling apparatus or in a combined heat-and-power coupling system, comprising:
an arrangement comprising multiple converter devices (3a, 3b), wherein each of the converter devices (3a, 3b) has one or more thermoelastic elements (4) arranged in a direction of extension;
a loading device, in order to load the thermoelastic elements (4) of each of the multiple converter devices (3a, 3b) so as to have a temporally variable power curve,
a coupling which is configured to actuate the loading device which controls the converter devices (3a, 3b) in a phase-offset manner with respect to their cyclic loading and unloading,
wherein the thermoelastic elements (4) within one or more of the converter devices (3a, 3b) are each arranged parallel to each other in a frame (2, 2a, 2b, 2c, 2d), such that the converter devices (3a, 3b) form one or more substantially planar heat exchanger planes, which are entirely contained within the frame (2, 2a, 2b, 2c, 2d).
