The invention relates to the field of devices used to transfer heat or cold in the processes using streams of warm liquid or gas to the cooler parts and in the opposite direction from cold liquids and gases to the hotter, and can be used in heating, ventilation, chemical, food and other industries.

The famous "Heat engine", A.S. No. 1539391, MKI F03G 7/06 having a deformable membrane from a material with thermo-mechanical memory.

The downside of it is the complexity and impossibility of heat transfer in liquid or gaseous environment.

As the prototype is set to "Method of heat transfer in heat exchange systems, A.S. No. 1611913, MKI SC 5/00, which consists in the forced transfer pump heat transfer liquid from one heat exchanger to another.

The downside of it is the need to supply energy for the operation of the pump.

The aim of the invention is to accelerate the transfer of heat (cold) or liquid (gas) from one layer to another without the supply of energy for its movement.

This goal is achieved by the fact that in the method of heat transfer in gas and liquid environments, including moving the carrier to the consumer, to accelerate the transfer of heat or cold to the consumer, in the liquid or gas is placed capsules with varying volumetric weight about the action of temperature, that warm liquid or gas from the top down and transported produce, and at the bottom trying to enter more cold liquid and is transported upward, and capsules made in the form of a shell with insulation, which has a capacity, Luggage buoyancy to the movable wall and its thermal actuator; capacity there are openings of the intake-release and the valve, the locking fluid or gas in the tank and driven by temperature actuator made in the form of bimetallic material with heat transfer capacity of the heat-absorbing fill material; in the capsule has a magnet or magnetic material, and at the bottom electromagnet driven the current received from the motion of capsules with magnets inside conductive helix, located along the movement of the capsules.

The heat transfer is performed by means of capsules having the chamber buoyancy to the movable wall and its thermal actuator in the form of a bimetallic material (rod), heat-absorbing material or a container for liquid (gas) with the holes in the intake-release that lock valves, actuated from the bimetallic core. To keep the capsules at the bottom to complete the heat transfer include a magnet or magnetic material, and at the bottom electromagnet driven by a current derived from the movement of the cap the street with magnets inside conductive spiral, located along the movement of the capsules.

The method consists in transferring the heat from the warm upper layers at the bottom and cold from the lower to the upper layers by changing the volumetric weight of the capsules from the temperature.

Figure 1 shows a diagram of the implementation of the method according to the local transfer of the capsules of the warm liquid in the lower cold layers, the 1st option.

Figure 2 shows a diagram of the method for heat transfer capsules pipes, version 2.

Figure 3 - type II figure 2 depicts the device of the pipe and the scheme of movement of capsules.

Figure 4 - type III in figure 2, shows a diagram of the movement of the capsules at the bottom of the pipe.

Figure 5 shows a scheme of the method for heat transfer capsules in a large volume environment, 3rd option.

Figure 6 - type IV in figure 2, a variant of the device of the capsule heat transfer.

Figure 7 - type I in figure 1, a variant of the device of the capsule-carrying liquid or gas.

On Fig - V figure 5, a variant of the device of the capsule with thermomagnetic material heat transfer.

The device has a body 1 having top and bottom of the hole 2, the casing is mounted a conductive helix 9, and placed inside capsules 3 two options. The first option (for heat transfer) is a shell 10 from the top, closed by insulation 13. Inside the shell 10 is attached to the magnet 7 or thermomax any material, movable partition wall 5 and the temperature of the actuator 4 in the form of a bimetallic rod, the rest of the shell 10 is filled with a heat absorbing material 11, a part of which is in contact with the environment. The second variant differs in that the shell 10 is formed of a container 14 having apertures 15, one of which is closed by a valve 16 through a rod 17 connected with the bimetallic core.

The method is as follows. On Wednesday fluid (gas) is set housing 1 having holes 2, in which is placed the capsule 3. In the upper part of the body is fluid with higher temperature, under the influence of which is bent bimetallic core temperature of the actuator 4 capsules 3 by moving the movable wall 5, this decreases the volume of the chamber buoyancy 6, this volume weight capsules 3 increases and it sinks to the bottom. As cooling (heat transfer) bimetallic rod returns to its original position by moving the movable wall 5, the chamber volume buoyancy 6 increases and decreases the volume weight of the capsule 3, which POPs up. At the bottom of the capsule 3 is held until the full heat transfer due to installation in the capsule 3 magnet or magnetic material 7 that changes the magnetic properties from the action of temperature, and at the bottom of the electromagnet 8, the current for which is about is produced by the movement of the capsules with magnets inside conductive spiral 9.

There are three ways of heat transfer.

In the first embodiment is transferred medium (liquid or gas) from the heated layers in colder with their mixing. In this case, the capsule 3 cover bimetal rod heat-absorbing material 11. The formed container 14 through the openings 15, passing through the shell 10 and the heat insulating layer 13, is connected with the external environment. In one of the holes 15 installing the valve 16 associated with the help of traction 17 with the movable wall 5. In the upper warm layer of fluid through the openings 15 fills the tank 14. Heat-absorbing material 11 transmits heat to the bimetallic rod, which moves the movable wall 5 and the rod 17 with the valve 16 closes the aperture 15. By reducing the volume of the chamber buoyancy 6 capsule 3 together with warm liquid falls to the bottom. At the bottom of the capsule 3 to full cooling is delayed due to the attraction of the magnet 7 to the electromagnet 8, installed on the bottom of the housing 1. The current for the electromagnet is created when the movement of the capsules 3 along the wall of the housing 1 in which is mounted a conductive helix 9. Upon cooling, the bimetallic rod moving with the help of traction 17 and valve 16 opens holes 15 and the warm liquid is expelled cold. Upon further movement of the bimetallic rod increases the chamber volume I of buoyancy 6 and the capsule with cold liquid rises to the top.

In the second embodiment, heat is transferred to the body 1, made in the form of pipes. The shell 10 of the capsule 3 is filled with heat absorbing material 11, such as paraffin. In this case, the first through the surface 12 is heated heat-absorbing material 11, and then is heated to the temperature of the actuator 4, the bimetallic rod which moves the movable wall 5, reducing the amount of camera buoyancy 6. To protect bimetallic rod from premature cooling, the shell of a capsule 3 outside of the cover insulating layer 13. At the bottom of the capsule 3 to full cooling is delayed due to the attraction of the magnet 7 to the electromagnet 8, installed on the bottom of the housing 1. Electric power to the electromagnet is created when the movement of the capsules 3 along the wall of the pipe body 1 in which is mounted a conductive helix 9. Through the surface 12 cools the heat-absorbing material 11, and then the bimetallic rod, which, curving, returns a movable partition wall 5 in the initial state, increasing the chamber volume of buoyancy, while the reduced volume weight capsules 3 allows it to float to the top.

In the third embodiment, heat is posted capsules 3 large amount due to the fact that the heat capacity of the shell 10 is made, for example, in the form of lenses, and the temperature of the actuator 4 in the form of a bimetallic disc. Bimet lichecki the disk and the lens shell 10 to form a chamber buoyancy 6, on the wall of which is attached thermomagnetic material 7. The bimetallic disc is closed by insulation 13. In the warm upper layers of the liquid shell 10 absorbs heat, it heats up the bimetallic disk is closed from the outside with insulation 13, which, bending, reduces the amount of camera buoyancy 6. In this position, the bimetallic disc is held thermomagnetic material 7. Due to its shape capsule 3 performs oscillating motion transmitting heat a larger volume of fluid. Along with the shell 10 capsules 3 cools and thermomagnetic material 7, its magnetic properties are reduced, and the bimetallic disc is returned to its original position, the volume of chamber buoyancy 6 increases and the capsule POPs up.

The present invention allows using internal heat, to effect heat exchange between the upper and lower liquid layers, and also to get electricity.
