Description

The utility model relates to devices for converting electrical energy into thermal energy by means of a tubular electric heating element (TEN) and using a liquid, mainly water.

A steam condensate heater is known, comprising a sealed hollow metal casing with nozzles, forming a heating chamber filled with liquid, a tubular electric heating element (TEN) located inside the casing with current-carrying leads, the heating chamber is inclined toward the end wall of the casing with the tubular electric heating element at an angle of 10 ° -20 ° to the horizon on different-sized support posts spaced at the ends of the housing, the tubular electric heating element is fixed end wall of the housing and positioned within the heating chamber below the level of the liquid surface in the operating state (see. the description of utility model to RF patent №63038, IPC F24H 1/20, publication 10.05.2007).

The disadvantages of the known steam condensate heater are quite large overall dimensions, a long heating time.

The objective of the claimed utility model is to obtain a heater with a high efficiency, small dimensions, corresponding to sanitary standards for use in rooms for various purposes.

The essence of the claimed utility model is as follows.

A steam condensate heater containing a sealed hollow body with filler and drain nozzles and with plugs in them, a heating chamber filled with liquid is formed in the housing, at least one tubular electric heating element with current-carrying leads is installed in the heating chamber below the surface of the liquid and mounted on the end wall the housing, the housing is located on a support column obliquely at an angle to the horizontal, the housing is made in the form of a radiator with lower and upper horizontal collectors, flat These are tightly interconnected by vertical pipes, a drain pipe with a plug is installed at the bottom of the lower manifold, a filler pipe with a plug is installed on the upper collector, a thermocouple and a safety relief valve are formed in the lower manifold, a liquid-filled heating chamber, the radiator is inclined on the support column at an angle of 75 ÷ 85 ° to the horizon and is closed by a casing with holes in its upper part for the outlet of heated air, the findings of a thermocouple and a tubular electric heating element that are connected to an electronic control unit.

This allows to reduce the overall dimensions of the heater, through the use of a heat pipe, increase the heat transfer from the heater to the surface of the heater radiator, and due to the electronic control unit, provide the required temperature control inside the heated room.

The essence of the utility model is illustrated by drawings, where:

figure 1 shows the steam condensate heater Assembly, General side view;

figure 2 - also, a radiator with a control unit, front view;

figure 3 is also a support post, front view;

figure 4 is also a casing, front view.

The steam condensate heater contains a sealed hollow metal casing, which is made in the form of a radiator 1 with a lower horizontal collector 2 and with an upper horizontal collector 3, the cavities of which are hermetically connected to each other by vertical pipes 4. Fins are installed on the vertical pipes to increase the heat exchange surface area. On the lower collector 2, a drain pipe 5 with a plug 6 is installed from below. On the upper collector 3, a bulk pipe 7 with a plug 8, a thermocouple 9 and a safety relief valve 10 are installed. A heating chamber filled with liquid is formed in the lower manifold 2. In the heating chamber of the lower manifold 2 below the surface of the liquid there are two tubular electric heating elements (TEN) 11 with current-carrying leads and mounted on the end wall of the radiator 1. Radiator 1 is located on the support column 12 obliquely at an angle of 75 ÷ 85 ° to the horizon and is closed by a casing 13 with holes 14 in its upper part for the exit of heated air. The findings of the thermocouple 9 and two tubular electric heating elements 11 are connected respectively to the electronic control unit 15.

Steam condensate heater operates as follows. When you turn on the tubular electric heating elements (TEN) 11 in operation, the water in the lower horizontal collector 2 begins to heat up, partially evaporates. Water vapor rises along the vertical pipes 4, enters the upper horizontal collector 3. In the upper horizontal collector 3, water vapor condenses, during condensation, heat is transferred to the metal walls of the collector. Condensate along the walls of the vertical pipes 4 flows into the lower horizontal collector 2, then the described cycle is repeated. During steam condensation, heat is transferred to the metal walls of the upper horizontal collector 2 and the walls of the vertical pipes 4. After heating the radiator casing 1, the process of heat transfer from the heated metal walls of the casing to the room air begins. The radiator 1 of the steam condensate heater is placed in the casing 13, which allows to reduce the radiant component of heat transfer and increase the convective component. In the upper and lower parts of the casing 13 are openings for convective heat transfer. In the process of operation of the heater, the electronic control unit reads the EMF of the thermocouple 9 and controls the on and off of the tubular electric heating elements to maintain the set temperature in the heated room.

The claimed utility model allows to reduce the overall dimensions of the heater, through the use of a heat pipe, increase the heat transfer from the heater to the surface of the heater radiator, and due to the electronic control unit, provide the required temperature control inside the heated room.
