<p>Device for utilizing heat via conversion into mechanical energy having a travelling wave heat motor (1) comprising a self-enclosed conduit (2) which defines internally an endless channel filled with a compressible fluid, a regenerator (3) arranged in a portion of the channel and comprising a heat exchanging medium (7) through which the fluid can flow, heat supply (4) and heat discharge (6) means coupled in the lengthwise direction of the channel at a mutual interval to the heat exchanging medium which means can generate a temperature gradient in the regenerator during operation, whereby the length of the channel is dimensioned in accordance with a design wave length of a travelling wave with a desired frequency to be generated in the channel during operation, and with energy extraction means (9) absorbing mechanical energy from the travelling wave. Connecting onto the channel portion containing the regenerator on the side of the heat supply means is a channel portion which has at least the same diameter as the channel portion in which the regenerator is accommodated and which is provided with means for neutralizing wave phenomena in the fluid reflected in the direction of the side of the regenerator coupled to the heat supply means.</p> |
