1 is a high temperature water tank, 2 is a low temperature water tank, and both water tanks 1 and 2 are connected by a communication pipe 3 extending in the horizontal direction. The high temperature water tank 1 is provided with a heater 4 for heating the water stored in the water tank (the heater is tentatively shown as a heat source and is actually a heating element of an electronic device, etc.) 4. A vibration exciter 5 for vibrating the water in 1 is provided.

In the above-mentioned structure, when the water in the high temperature water tank 1 is heated to the required temperature by the heater 4 and is vibrated by the vibration exciter 5, vibration is generated in the low temperature water tank 2 via the water in the communication pipe 3. Although propagated to water, heat moves to the low temperature water tank 2 side due to this vibration.

Almost no convection of water occurs in the communication pipe 3,
Therefore, vibration is indispensable for the heat transfer in the communication pipe 3, and if the vibration is stopped, the heat transport is also stopped. Further, since the heat transport amount is also determined by the vibration amount, the vibration amount may be increased when the transport amount is desired to be increased and the vibration amount may be reduced when the transport amount is desired to be decreased.
次に、第2図〜第5図に於いて連通管8内での熱移動の
