Which heater is the best way to heat?

An introduction to heaters

The so-called heater refers to the equipment used for heating. Although there are many kinds of heaters on the market, the most common is the electric heater. As the name suggests, the electric heater is a heating device that uses electricity as energy for heating and heating, and it can also be called an electric heater.

The heat transfer methods of electric heaters are mainly conduction and radiation, such as: electric blanket is direct contact conduction; quartz tube electric heater stone heat radiation; heater is warm air convection; air conditioner stone warm air convection; electric oil heater is slow air convection, etc. In fact, any kind of heater has two heat transfer effects of radiation and convection. If a certain heater is dominated by radiation heat transfer, it can be called a “radiant heater”; if it is dominated by convective heat transfer, then It can be called “convection heater”. The types of electric heaters can be divided into electric heating heaters, PTC fan heaters, convection electric heaters, electric heating film electric heaters, and high-temperature superconducting heaters due to different heating principles, heat dissipation methods, heat transfer media and application scope.

Second, the heater products

In the face of many heater products, what are their characteristics? What kind of heating method is the heater good? Which heater should I choose? Let’s take a look at some product introductions of heaters and the characteristics of heaters with different heating methods:

1. Thermal heater

Also known as electric heating oil, this kind of heater cavity is filled with heat-conducting oil, and there are large-area heat sinks on the outside. When the power is turned on, the heat-conducting oil around the built-in electric heating element is heated, and then dissipates heat to the space through the heat sink. achieve the purpose of heating. In addition, it also has infrared radiation and convection effects, so it can be said to be a composite heater. Its characteristics are that the heat transfer oil does not need to be replaced, the service life is long, and it has the advantages of safety, hygiene and dust-free; the disadvantage is that the energy consumption is relatively high, the heat The inertia is large, and the temperature rises slowly.

2. Heater

That is, forced ventilation heaters. This type of product uses the fan in the heater to inhale the cold air in the room from the air inlet, flows through the electric heating element to heat up and then sends out the hot air from the exhaust port, so as to achieve the purpose of heating. Its characteristics are that the power can be automatically adjusted, the temperature is self-limited, the heating speed is relatively fast, and the room temperature is relatively uniform and comfortable. Air quality has declined.

3. Electric film heater

Including high temperature electric heating film heater and low temperature electric heating film heater, it belongs to radiation type heater. This kind of product uses the electric heating film as the heating material, which is a product that has developed rapidly in recent years. It has the characteristics of good water tightness, softness, resistance to folding, corrosion resistance, and aging resistance. The heat is transferred by radiation. In addition, the heating element of the electric heating film can also be combined with the decorative painting to make a wall-mounted or desktop electric heating painting, which is a beautiful and practical multi-functional handicraft. But the market is still immature and there are not many products.

4. Convective heater

Convective heaters have high safety performance and quiet operation. The disadvantage is that the temperature rises slowly, the indoor temperature uniformity is poor, and the flowing air will produce a certain degree of dust pollution.

5. Composite heater

The compound heater uses any two or more combinations of radiation, convection and forced ventilation to transfer heat to achieve the purpose of heating the room.
