Convection heater is the use of natural convection principle the air heated by the heating device?

Convectors are a type of heater. The other is radiant heaters. Convection heaters have two types of natural convection and forced convection. Convection heater is the use of the principle of air mobility, air microcirculation way to conduct heat in the indoor air no sensible air flow, will not make the body have uncomfortable feeling.

Electric heating method used more abroad, the domestic rapid development in recent years, mainly divided into two kinds of convection and radiation. Due to high electricity prices, in order to reduce operating costs, electric heating is usually intermittent heating. Therefore, heating temperature heating process of indoor temperature law, distribution and operation of temperature control device, heater design and operational control of the foundation.
Convective heaters convert electrical energy into heat, and the resulting heat is instantly released by the flowing air to the air, allowing the room air temperature to rise evenly over a short period of time. Convection heater convection is the use of hot air movement carries a lot of heat; amount of indoor air heating, it can bypass the barrier spread to every corner of the room, effectively expanding the heating area.
The heater has the advantages of one in line with the requirements of ergonomics and comfort, the use of air convection heat transfer; second, higher safety performance, quiet operation; third is not dry. The disadvantage is slow warming.

Convection heater is the use of natural convection principle, the air heated by the heating device, the upper part of the outflow from the heater, indoor cold air from the bottom of the electric heater into the formation of circulation in the room to achieve heating. The difference between a forced convection electric heater and a natural convection electric heater is that the former is equipped with a small fan inside to speed up the circulation of indoor air.

Various types of heaters have a sound security and temperature control agencies. The dump switch is a special safety device on the space heater. The function of the dump switch is to cut off the power immediately when the heater is dumped, so as to effectively prevent the electric heating element from touching the floor or the carpet to cause a fire. Temperature control agencies are mainly overheating safety thermostat and adjustable or thermostatic regulator. The former controls the maximum operating temperature of the heater, which controls the actual operating temperature of the heater. More upscale products often with power selector switch, with two or three heating power for users to choose according to need.
