The invention relates to the field of heat and can be used in civil and industrial construction.

Known thermal battery (TA), which include the heat storage body and the environment.

The design THAT was adopted for the prototype described in [1] .

One of the main thermal characteristics TA is the time dependence given heat capacity per working cycle. Under a work cycle THAT is commonly understood as the total time between two successive process steps, such as charging THAT".

The dissipation Q "ideal" THAT during the day remains constant. In Fig. 1 shows the typical dependence of the heat for the "ideal" and the real ONE. Naturally, the closer the time response of THE real to the same "ideal", the better its working har is by approaching his performance to "perfect".

To ensure the discharge of a certain amount of heat Q in specific conditions (e.g., accommodations) need some surface F, which, as a rule, is the external surface and THE additional fins being in thermal contact with him. A layer of thermal storage medium adjacent to the surface of F should not be too large, since the solidification front extends from the outer surface to the center and creates a solid layer with a high thermal resistance. More than this layer, the worse the time response of the TA.

It should be noted difficulties "charging". The heating device is installed, as a rule, inside the heat storage medium, it is necessary to mount or additional cover for his possible replacement, or fill it, making THAT not maintainable.

The aim of the invention is to improve performance at the expense of increasing the uniformity of heat relief time.

This objective is achieved in that the heat storage medium installed heat pipes (one or more), one end of which is fixed on the surface of heat relief.

s 2, surface discharge heat 3 heat pipes 4.

SHE works as follows.

After "charging" thermal storage medium is in a liquid state. Suppose that the temperature of thermal storage medium located within the freezing temperature.

In the "discharge" THAT releases heat into the environment in two ways: through the housing 1 in the area of contact with the heat storage medium 2 and the heat pipe 4 to the surface of the heat-relief 3.

Thus, freezing the environment occurs as a side housing, and the heat pipe or heat pipes, if one is not enough).

The advantage of this scheme compared to the prototype is more uniform discharge of heat over time. THE proposed implementation can be supplied with large amounts of thermal storage environment, because this limitation with the use of heat pipes, i.e. with the possibility of heat removal from any of the zones THAT loses relevance. In addition, the surface heat relief can be constructively post itself that allows for architectural maneuver when designing.

Consider the process of "charging" ONE.

It is the most convenient of podotremata it in the liquid phase. The use of heat pipes can greatly simplify this task. If the second end of the heat pipes mounted on the heater (heat source), the applied heat is easy to apply to any area of thermal storage medium. In addition, removable replacement heater because it can be outside and can be easily dismantled. Themselves heat pipe repairs do not need, because they contain elements subject to wear over time.

Thus, the use of heat pipes in the construction of THE specified combination allows you to bring the daily cycle of THE real to the "ideal" and to significantly simplify the design, the realization should give economic effect.

1. HEAT ACCUMULATOR, comprising a housing with a surface heat relief filled heat storage substance, characterized in that, to order performance by improving the uniformity of heat relief time, in the heat storage substance is installed at least one heat pipe, one end of the fixed on the surface of heat relief.

2. The battery under item 1, characterized in that at the other end of the tube is placed a heater.

SUBSTANCE: invention refers to heat exchange devices used for heat or cold transfer in the processes using liquid or gas flows, and can be used in heating and ventilation systems, in chemical, food and other industries. Heat exchange method in gaseous and liquid media consists in transfer of heat or warm liquid (gas) from upper layers of medium to lower ones by means of capsules consisting of cover with heat insulation in which there is tank filled with heat-absorbing material or liquid (gas) and flotation chambers with movable partition brought into operation with temperature drive in the form of bi-material. Capsules are retained on bottom till heat transfer is completed owing to magnet or thermomagnetic material installed in capsule, and electric magnet installed in lower layers; at that, current for electric magnet is generated when capsule with magnet passes along current-conducting spiral located along capsule movement.

EFFECT: proposed invention will allow, by using internal heat, performing heat exchange between upper and lower layers of liquid (gas), as well as producing electric power.
