Abstract

The invention relates to a heat exchanger tube device, in which there is a combination of a heat exchanger tube and a shaker which causes the tube to reciprocate essentially along its longitudinal axis. A special embodiment of the heat exchanger tube device is used to cool reciprocating engine parts, e.g. pistons of internal combustion engines, especially two-stroke engines, in which use is made of an engine-specific device to remove heat from the engine part (4) to be cooled to a heat sink in the form of a hermetically sealed heat exchanger tube (6), one end of which is in heat transfer contact with the engine part (4) to be cooled, and which extends along the longitudinal axis in the direction of reciprocation of said engine part (4) as far as the heat sink and is filled with a given quantity of a known working liquid (16) for a heat exchanger tube which is evaporated by the heat to be dissipated.
