Energy efficient electric infrared heaters

Research area – energy saving technologies.

Purpose – for the arrangement of heating points, checkpoints, field medical points, food preparation points (catering units).

Scope of application. Creation of efficient, compact, mobile heat registers, air heaters, convectors, dryers, heat guns, heat curtains, fan heaters, infrared heat heaters.

Description. The new technology, which replaced tubular electric heaters (TENs), is based on the use of heaters manufactured using new innovative nanotechnology. The heater is made in the form of a metal base 1 … 8 mm thick with a dielectric coating. On the substrate (of any shape), a drawing is printed with a special conductive resistive paste (of any configuration), which is the outline of an electrical circuit that is reliably isolated from the external environment. Heaters generate intense, directed heat radiation. Heaters provide uniform heating over the entire area of ​​the heat sink by optimizing the development of the resistor pattern topology. The technical parameters of the heaters (supply voltage, power, operating temperature) can be varied within wide limits without changing the heater design, only by changing the resistive paste rating. Several compact electrical circles with different technical parameters can be created on one substrate. In the production of heaters, standard equipment is used, the manufacturing process is easily automated.

Advantages. The technology is based on the use of a system of composite nanostructured materials that differ in their properties, which makes it possible to obtain a new heating element with unique properties:

  • reduced energy consumption – when creating the same thermal effect, the consumption of electrical energy of thermal devices is 5-30% less than on conventional heating elements due to a much larger (compared to heating elements) heat transfer surface, and a significantly smaller thermal barrier from the heating layer and heat sink.
  • reliability – the study of heaters and the practice of their long-term use have shown the high reliability of the products. So, industrial electric burners have been operating without failure for more than five years (about 12,000 hours), while the service life of standard cast-iron electric burners on heating elements of various world manufacturers is usually no more than 2000 … 3000 hours.
  • self-regulation of power consumption – heaters can operate without external regulation, since resistive pastes create a posistor effect (high positive temperature coefficient of resistance). The self-regulating property protects thermal devices from overheating and insufficient heating, ensuring the stability of temperature parameters during operation. Using the corresponding value of the resistive paste, it is possible to preset the required temperature mode of the heater operation.
  • low thermal inertia – the direct transfer of heat from the heating film to the substrate of the heat receiver causes an extremely low thermal inertia of the structure, which ensures a quick release of the heating device to the operating mode. This feature of the heaters opens up new possibilities for their special application.
