Heat receiving equipment

Technical field

This technical solution relates to a device for receiving heat from a heating unit, in particular a fireplace, and transferring it to a room.

BACKGROUND OF THE INVENTION

The need for heating devices of this kind is considerable and steadily increasing, while fireplace inserts require continuous improvement, resulting in better efficiency while requiring less heat-producing material and emitting less unwanted gases.

Attempts have been made to inject air flow over the surface of gray cast iron from which fireplace inserts are made. This caused more efficient heat absorption from the gray cast iron surface.

The prior art publication WO 9729327 discloses a gas heating apparatus having a turbine rotatably mounted in a first conduit through which exhaust gases flow. The turbine is in drive communication with the freely rotating fans located in the second conduit immediately downstream of the gas burner so that the flowing air is heated in the second conduit and drawn by the conduit by the fans that expel the flowing air into the room.

Another solution of the prior art, Polish Utility Model Application PL 116824, discloses a heating furnace with a heat exchanger having in the housing constituting the air chambers a fireplace insert with a furnace and an exhaust pipe, the heat exchanger being located in the air chamber at the top of the housing fireplace and exhaust pipe. The heat exchanger consists of tubes with radiators. Between the housing and the fireplace insert there is a wall separating the heated air from the cooled air.

The essence of the technical solution

The challenge confronted with the currently developed technical solution was to develop a device that would increase the air flow around the heated furnace material, especially around its rear wall, to receive heat and dissipate it into space.

A device receiving heat from a heating unit with a turbine and a flow conduit is characterized in that an electrically driven turbine in the housing is provided on its housing. The apparatus is further provided with a thermostat comprising a regulator and a temperature sensor in the form of a head, which are connected to each other by a capillary tube, and the housing and the rear wall of the heater unit simultaneously form a flow line parallel to its rear wall.

Preferably, the thermostat has a control range between 50 ° C and 300 ° C.

Preferably, the openings are protected by a sieve.

Preferably, the device is used in heating units such as a fireplace.

Preferably, the turbine is equipped with vibration prevention plates.

The design of the device is universal and can be applied to any heating unit in the form of a fireplace after the introduction of the flow line modifications. The present technical solution considerably increases the comfort of the use of the fireplace, since the user has the possibility to decide at which temperature of the rear wall the system is switched on and starts to transfer heat to the room more effectively.

In addition to increasing the thermal efficiency, the functionality of the device is also increased. Better efficiency means that less fuel (wood) is required to generate nominal power, making the heating unit more economical. For the end user, this means fewer fuel doses to the heater unit, as well as savings. The above solution reduces the emission of harmful gases into the environment.

Clarification of the drawing

The subject matter of the present invention will be more clearly understood from the following exemplary embodiment of the invention and the accompanying drawings, in which:

Fig. 1 shows a perspective view of a hearth with a heat receiving device; and Fig. 2 shows a side view of a hearth with a heat receiving device provided on the housing.

Example of technical solution implementation

In a preferred embodiment, the heat-receiving device comprises a turbine 3 in a housing 6 mounted on a housing 2, which together with the rear wall 1 of the furnace forms a flow line parallel to the rear wall 1 of the furnace. Housing and housing are made of structural steel S235JR. The individual elements of the structure are cut from sheet metal by laser with an accuracy of up to ± 0.03 mm and subsequently bent on a bending press. The use of such machines (CNC) in the production process ensures that the individual elements of the system are perfectly matched. The cover 6 of the turbine 3 has two openings 7, 8 through which cold air is drawn in from the outside and directed along the flow duct. The openings are protected by a special screen, preventing the user from contacting the turbine blades. The end of the flow conduit is shaped to direct the heated air above the fireplace towards its front. A single-phase thermostat is connected to the turbine electrical circuit. The thermostat comprises a regulator 5 and a temperature sensor 4 in the form of a head, which are connected to each other by a capillary tube. The head is mounted directly on the rear wall of the fireplace at a location previously determined in tests carried out using a pyrometer (contactless thermometer). The thermostat control range is between 50 and 300 ° C. The user has very convenient access to the controller and its operation is intuitive. To prevent vibration on the flow line, vibration prevention plates 9 were used during the assembly of the turbine. The turbine is powered by 230 V mains and produces a sound of about 35 dB, which does not affect the comfort of the system. Turbine efficiency lies in the range of 135 m ³ / h with a maximum power input of 26 watts. If needed, the system can be equipped with higher efficiency turbines. Electrical connections are made using silicone cables for higher temperature ranges. The cables used are halogen-free (do not release harmful gases when burning) and are self-extinguishing. The electrical cable is connected to the housing by means of a folding bushing. Such a solution prevents damage to the cable from wear and tear. The device is grounded to comply with strict safety regulations.
