The heater is a necessary heating artifact for families without heating in winter. The winter without heating and kerosene heater is very difficult. Especially in the south, every family has no heating. In winter, the indoor temperature is about the same as the outdoor temperature. At this time, the heater is the Savior of family life. There are many kinds of heaters sold on the market. Different heating methods of heating can achieve different heating effects. This article summarizes several heating modes of heaters on the market and the characteristics of heaters with different heating modes.
Electric heater
Also called oil filled electric heater. The electric heater is filled with a new type of heat transfer oil. When the power is connected, the heat transfer oil around the electric heating pipe is heated, and then the heat is radiated along the heat pipe or scattered sheet. When the oil temperature reaches 85 ℃, the temperature control element will automatically power off. The heat transfer oil of the electric heater does not need to be replaced and has a long service life. The selling price is generally between 400 and 500 yuan. It is suitable for use in living room, bedroom, aisle and families with elderly and children. It has the advantages of safety, sanitation, dust-free and tasteless. The disadvantages are slow heat dissipation and high power consumption. There are 7, 9, 10 and 12 Youting heat sinks. The power can be adjusted by selecting the number of heat sinks, and the use power is about 1200 watts.
Far infrared heater
Also called quartz tube heater. The far-infrared quartz tube is used for heating. The heat transfer mode is radiant heat. It has strong penetration, but the heat is not easy to diffuse, and the thermal efficiency is low. There is open fire and consumes oxygen. Due to backward technology, this product is rare in the market, and the price is relatively cheap. It is about 100 yuan. It is suitable for local heating in families.
PTC heater
PTC is the abbreviation of ceramic electric heating element. It uses the fan to blow the air through the PTC electric heating element for forced convection, which is the main heat exchange mode. A temperature limiter is installed inside. When the air outlet is blocked by the fan, it can cut off the power automatically. Some are also equipped with a dumping switch, which can cut off the power supply automatically when the heater dumps. The output power is 800-1200 watts, the temperature can be adjusted at will, the air supply is soft during operation, the temperature rises quickly, and it has the function of automatic constant temperature. PTC components generally have waterproof function, so it is suitable for use in the bathroom. The price is between 300-500 yuan. It is an ideal portable household electric heater at present.
Convection electric heater
The upper part of the electric heater shell is an air outlet and the lower part is an air inlet. After power on, the air around the electric heating pipe is heated up and flows out of the air outlet, and the surrounding cold air enters the supplement from the air inlet. Such repeated circulation can improve the indoor temperature. When the inlet and outlet are blocked or the ambient temperature is too high, the temperature control element will automatically cut off the power supply of the electric heating tube. The use power of this electric heater is about 800 watts, and the power can be adjusted by increasing or decreasing the number of electric heating tubes. The electric heater has high safety performance and quiet operation, with the disadvantage of slow temperature rise.
Electric film heater
It adopts fully transparent high-temperature electric heating film as heating material, which is at the world advanced level in technology. The hot air duct structure is adopted. The heat transfer mode is enhanced convection. The hot start speed is fast. The air outlet temperature can reach more than 100 ℃ within 3 minutes, but it will be cooled quickly after power failure. Because the electric heating film has no oxidation when heating, its service life can be 100000 hours. At the same time, it has the characteristics of small volume and beautiful appearance. It is a replacement product of the electric heater family. Siphon heat pipe heater this is a new electric heater this year. It uses' two-phase closed thermosyphon 'as the heat source, with fast temperature rise and high thermal efficiency. It does not emit light, has no open fire, and is not afraid of water drenching and steam corrosion. It is suitable for ordinary rooms and bathrooms. The price is about 400 yuan.
Quartz tube electric heater
The heating element is an electric heating wire, which is threaded in a quartz tube. Light is generated during work and should not be used in the bedroom. This electric heater is suitable for small rooms of about 10 square meters, with a retail price of about 130 yuan. Because the electric heating wire is easy to oxidize, it is rare.
Halogen heater
Halogen tube is a sealed luminous heating tube filled with halogen elements. Because it depends on light and heat dissipation, it is not suitable for bedrooms. It is suitable for rooms of about 12 square meters and the selling price is between 100 and 200 yuan.
High temperature superconductor
It generates heat by heating superconducting hot oil and transfers heat by fan. It is suitable for reception room and bathroom. The price is high, generally between 500 ~ 600 yuan.
