18 is a snake pipe 18a=! = An evaporator consisting of fins 18b, one end of which is connected to one end of the condenser 10 in the bellows 7 via a vapor transfer pipe 19, and the other end of which is connected to the condenser 10 via a liquid descending pipe 20. are connected to the other end of each.

The liquid downcomer pipe 20 is provided with a tank 21 for storing an evaporated liquid 8b (eg, fluorocarbon, alcohol) and an inverted U-shaped portion 22.

23 is a heater attached to the rising portion of the inverted U-shaped portion 22.

These 10.18 to 23 constitute a heating heat flow control siphon H.

Next, the operation of this embodiment configured as described above will be explained.

First, the action of the cooling heat flow control siphon C for cooling the evaporative liquid 8 or its vapor within the bellows 7 will be described.

When inputted to the heater 16 provided at the rising portion 15a of the inverted U-shaped portion 15, the liquid 8a therein boils, and the generated bubbles rise within the rising portion 15a due to buoyancy.

In this case, the surrounding liquid 8a is also pumped up by the pumping action of the bubbles, so that this liquid 8a descends within the liquid downcomer pipe 13 over the top of the rising portion 15a and flows into the evaporator 9.

This inflowing liquid 8a receives heat from the evaporative liquid 8 in the bellows 7 and boils, and the generated vapor is transferred to the vapor transfer pipe 12.
The vapor moves within the condenser 11 due to the vapor pressure difference, where it is cooled, releases heat of condensation, and liquefies.

This heat of condensation is removed by convection of an external fluid (eg, air, water) via the fins 11b.

On the other hand, the condensed liquid flows down into the tank 14 due to gravity, reaches the rising portion 15a of the inverted U-shaped portion 15, and repeats the same cycle as described above.

Note that the steam generated in the rising portion 15a by heating by the heater 16 flows into the condenser 10 through the pressure equalization pipe 17, where it is cooled and liquefied.

The evaporative liquid 8 within the bellows 7 is cooled by the action of the cooling heat flow control siphon C described above, and the internal pressure thereof decreases, so that the bellows 7 contracts.

Therefore, the pumped liquid 25 in the lower tank 2 flows into the lower part of the liquid pumping tank 6 via the check valve 4 of the liquid pumping pipe 3 and the communication pipe 5.

When the input to the heater 16 is cut off, the rising portion 15
The liquid 8a does not flow into the liquid downcomer pipe 13 since bubble generation in a is stopped.

Therefore, since the liquid 8a accumulates in the tank 14, the transfer of heat from the evaporator 9 to the condenser 11 is stopped, and the cooling action by the cooling heat flow control siphon C is also stopped.

Next, the action of the heating heat flow control siphon H will be described using FIG. 2.

In this case, the input to the heater 16 of the cooling heat flow control siphon C is cut off, and the action of cooling the evaporative liquid 8 in the bellows 7 is stopped.

When the input is now made to the heater 23 of the heat flow control siphon H for heating, the heat held by the external high temperature fluid is transferred from the evaporator 18 via the fins 18b of the evaporator 18 due to the same effect as the heat flow control siphon C for cooling described above. Condenser 1 in bellows 7
0.

As a result, the evaporative liquid 8 in the bellows 7 provided in the pumped liquid tank 6 is heated, so that the internal pressure increases.

For this reason, the bellows 7 is pushed down, so the liquid pumping tank 6
The pumped liquid 25 accumulated in the lower part of the tank flows into the upper tank 1 through the communication pipe 5 and the liquid pumping pipe 3.

In this case, since the check valve 4 is closed, there is no possibility that the pumped liquid 25 in the pumped liquid tank 6 will flow into the lower tank 2.

As a heat source for the high temperature fluid outside the evaporator 18, heated waste water, waste heat, solar heat, etc. are used.

By alternately turning on and off the inputs of the heater 23 of the heat control siphon H for heating and the heater 16 of the heat flow control siphon C for cooling, the bellows 7 expands and contracts.
can be moved from the lower tank 2 to the upper tank 1.

FIG. 3 shows another embodiment, which includes an arbitrary number (two in the figure) of the pumping liquid tank 6, a cooling heat flow control siphon C, and a heating heat flow control siphon H. A liquid pumping system of an arbitrary diagram (two in the diagram) is constructed by combining the two.

This configuration has the advantage that the pumped liquid 25 can be continuously transferred from the lower tank 1 to the upper tank 2.

FIG. 4 shows another embodiment.

This is the same as the above embodiment (Fig. 3) in that three pumped liquid systems are constructed by combining pumped liquid Kunkuro, cooling heat flow control siphon C, and heating heat flow control siphon H, but the cooling The difference is that each condenser 11 of the heat flow control siphon C for use and each evaporator 18 of the heat flow control siphon H for heating are integrally connected by shared fins 11b and 18b, respectively.

With this configuration, not only can the man-hours for manufacturing the condenser 11 and the evaporator 18 be reduced to save costs, but also a fan for supplying fluid to the outer surfaces of the condenser 11 and the evaporator 18 can be used. It also has the advantage of reducing the number of pumps.

〔Effect of the invention〕

As explained above, according to the present invention, no rotating parts are required to pump up the liquid to be pumped, so there are fewer failures and the reliability of the pump can be improved, and hot water, solar heat, etc. can be effectively utilized. It became so.
