Description

one

The invention relates to heating devices and is intended for use in water, steam or gas heating systems.

Known heating device containing a vacuum sealed enclosure with a coolant. In the lower part of the body tubular electric heaters l, are placed. The closest to the proposed device according to the technical essence and the achieved result is a heating device containing a hermetic case, partially filled with a heat carrier and a heater heated in a heat carrier as a channel for the passage of heating medium

AND.

In the specified devices heat transfer

from the heater to the housing, by evaporating the coolant on the heater surface and condensing the vapors on the walls of the housing.

However, with such heaters, it is necessary to regulate heat transfer manually or with the help of special regulators.

The object of the present invention is to provide automatic self-regulation of the heat transfer of the temperature of the surrounding air.

This is achieved by the fact that the casing is divided by a vertical hollow jumper into two compartments communicating in the upper part and connected in the lower part to a container filled with a liquid that is denser and easier to boil than the coolant, for example freon.

Such an embodiment of the device provides automatic self-regulation of the heat of the instrument by changing the pressure of the liquid vapors in the housing.

FIG. 1 shows a heating device in section. FIG. 2 - section aa

(FT1G.1).

The heater contains a sealed housing 1, partially filled with coolant 2, for example water. In the coolant, the heater 3 is immersed, having a channel for the passage of the Greek. The Kofsiyc 1 is divided by a vertical hollow plug with a hook 4 into two compartments 5 and 6, communicating in

the upper part and connected to the tank 7 filled with liquid §, which is denser and more easily boiled than the coolant, for example freon.

In a non-working device in case 1 there is a mixture of water vapor and freon. When passing through the heater 3 of the Greater Medium, water evaporates and the vapor enters the compartment 5. Due to the difference in the saturation temperature of water and freon, the vapors of the latter will be distilled with water vapor towards the compartment 6 through the channel 9, Simultaneously the vapor will occur on the internal surfaces x KOI rest 1, and the heater heats up.

When the ambient air temperature is below a certain level, the pressure and the amount of freon vapor in housing 1, determined by the temperature of tank 7, is small, and freon vapors will be completely displaced by water vapor into compartment 6. Water vapor condensation area will occupy the entire surface of the compartment 5, and. the instrument will work with the maximum capacity.

As the temperature rises, the temperature of the liquid freon in the tank 7 increases, and the pressure and the amount of steam in the housing 1 increase accordingly. Under these conditions, the interface between the water vapor and the freon will shift to the compartment 5, respectively, reducing the area of water vapor condensation and heat transfer 1. rlbora. The temperature of the air will begin to fall, causing the temperature of the walls of compartment 6 and capacity 7 to decrease, which will cause condensation of excess freon vapors in compartment 6 and runoff through passage 10

capacity 7. This will lead to the release of the compartment 5 from freon and to an increase in the heat transfer of the device.

The required range of self-regulation of the heater is established by selecting the appropriate pair: coolant-liquid and relative dimensions of the compartments and capacity.
