Description

Electric heater with at least one carbon layer

The present invention relates to the field of electrotechnical technology, namely an electric heating device comprising a carbon plastic (carbon) layer. Office or factory building, etc.) heating system features as the main heat source or additional energy-saving effective heat source.

As we all know, residential rooms, industrial plants, independent houses, etc. all use electrical equipment and systems for heating. These include radiator-type electric heaters, such as oil-based heaters or other types of heaters that use liquid as the heat carrier, as well as air-heating fan heaters, convectors, air conditioners, and infrared electric heaters.

The shell temperature of the oil radiator can be as low as 60°C, which will not cause indoor oxygen "burning", and is flame-retardant and noise-free.

The disadvantage of the oil radiator is the large capacity and the power consumption of 0.5kW to 2kW. When the radiator is used, it takes a long time to warm up the room, so the device is not used, has low efficiency, and cannot be used as the main heating device of the heating system. Also, the oil radiator is bulky, requires a lot of materials and has a complicated manufacturing process.

Heaters have low cost, but also have low efficiency and reliability, high energy consumption, easy to catch fire, and harmful to the air. At the same time, they cannot be used as the main heat source for indoor heating.

Heater power (checked online on 23 March 2018 at getoptim.com/uk/teploventilyator obigrivach.html) is 800W to 3kW.

A heater with a power of 2000W can heat a room of 20 square meters. Since the shutdown will cause the room temperature to drop immediately, the heater must continue to work. It can be seen that the efficiency of the heater is low, it will increase power consumption and the coefficient of performance is low. .

In addition, heaters are not completely environmentally friendly. Some bad manufacturers use plastic to make parts, and plastics will release harmful substances at high temperatures. Since heaters are used in closed rooms, this is extremely harmful to the health of users.

Equipment at high temperatures can cause a fire because the heating elements may be contaminated with flammable substances such as dust and fabric particles.

Electric convector is also a kind of heater we are familiar with,

The disadvantage is high energy consumption and low efficiency.

An electrical converter with a power of 1kW can heat a room of 10-12 square meters, but it cannot be used as a main heat source. Due to the high energy consumption and high material cost of the electrical converter, the system created is expensive, so it cannot be used to construct a heating system.

Air conditioners with heating are inefficient, energy-intensive, expensive, complex in design, and have limited use depending on climatic conditions.

The power consumption of the air conditioner is usually 1.6kW to 7kW. Some air conditioners consume 9kW of power.

When using an air conditioner for indoor heating, the shutdown will cause the indoor temperature to drop in a relatively short period of time. Therefore, the air conditioner should be turned on for a long time, that is, the air conditioner should continue to operate for heating, which leads to high energy consumption and high operating costs.

To sum up, as the main heating equipment, the air conditioner has high energy consumption, high cost, low reliability and low efficiency.

Infrared electric heaters are also known as heaters (http://sovet-ingenera.com/otoplenie/radiator-obogrev/kak-vybrat-karbonovyj-obogrevatel.html, http://aqueo.ru/otoplenie/ obogrevateli/obzor-plenochnykh-obogrevatelejj.html, http://www.teploline.com.ua/infraervoni-obihrivai.html), (Ukrainian Utility Model Patent No. 44667, IPC H05B1/00, H05B3/00, published in 2009 October 12, Bulletin No. 19; Ukrainian Utility Model Patent No. 115979, IPC H05B 3/16, published on May 10, 2017, No. 9 Bulletin; Ukrainian Utility Model Patent No. 65885, IPC H05B 3/00, published in December 12, 2011) are heating devices that dissipate heat by means of infrared radiation.

Infrared heaters create localized heating zones.

Infrared heaters heat items located in the room and then dissipate heat. (https://ru.wikipedia.org/wiki/%D0%98%D0%BD%D1%84%D1%80%D0%B0%D0%BA%D1%80%D0%B0%D1%81% D0%BD%D1%8B%D0%B9_%D0%BE%D0%B1%D0%BE%D0%B3%D1%80%D0%B5%D0%B2%D0%B0%D1%82%D0% B5%D0%BB%D1%8C, http://www.teploline.com.ua/infraervoni-obihrivai/teplov/the-principle-of-infrared-heaters.html, http://sovet-ingenera.com/ otoplenie/radiator-obogrev/kak-vybrat-karbonovyj-obogrevatel.html)

Infrared heaters are more energy efficient than the above heating devices when used in small rooms, but they cannot be used as the main heat source in a heating system.

The disadvantage of direct-acting infrared heaters is that they do not consistently provide comfort to indoor users, thus reducing the range of users.

When infrared waves act directly on the human body, the person is in a warm area due to the heat dissipation of heated furniture, floors, walls and other items. On the other hand, under the influence of radiant energy, the person generates heat. The best case would be to design the heater as a long wave heater, but this is not the case, the heater can emit mid and short infrared beams that are harmful to the human body, depending on the power, the human skin, the clothes you wear when it is heated. This effect is useless, and it is also something we do not want to see. It is not conducive to human health, just like people who stay in the sun for a long time will cause discomfort.

When the heater is fixedly installed on the ceiling or wall, its radiation direction cannot be changed, and it may radiate to the user's non-movable work area (such as the work area of the store cashier, the work area of the production workshop equipped with specific installation equipment) , work area with limited indoor space where students are located), users staying in such work area for a long time may cause discomfort and lead to unforeseen consequences such as health hazards.

In addition, the heating of the items in the room by the infrared heater can lead to some application defects of the infrared heater.

At present, many man-made and chemical materials are used in interior decoration. Also, most modern furniture and objects are made of man-made materials, plastics or chemicals. These materials and items will emit harmful pollutants when heated, which is not conducive to human health, especially when using high-power infrared heaters, they will emit short infrared waves.

At present, an electric heater is newly disclosed (RU Patent No. 132662, IPC H05B 3/30, published on September 20, 2013), which includes a casing, a heater and a heat dissipation assembly arranged in the casing. The volume unit of the channel also uses two thin-film heaters. These two heaters are arranged inside the front and rear walls of the casing, and are in contact with the above-mentioned casing walls and the heat-dissipating components arranged between the thin-film heaters. There is a steel plate that overlaps the top by 20-30%.

The upper and lower parts of the shell may be provided with openings, and the diameter of the opening of the lower part of the shell is larger than that of the upper part of the shell.

In addition, the heat dissipation assembly can be designed in the form of a radiator with vertical channels formed by parallel steel plates in its interior.

The thin film heater includes a curvilinear resistive heating element positioned between two flexible heat resistant electrically insulating films and having an output connected to a power source. The heating element is a single conductive wire that is bent to form a curvilinear element.

The electric heater is a convection heater and has the following disadvantages:

The heating of the air is carried out during the transmission of the film heater, which according to its design details causes the oxygen in the air to "burn" and evaporate the water. The heater also leads to overheating of the air, the heat dissipation components are contaminated with harmful substances released from the polluting particles, and therefore cannot be used continuously, long-term and at night, while the directional airflow of the heater cycle is partially diluted by the cold air, and the air is not diffused Therefore, the heater must not be fixed to walls, ceilings or other places where the whole room can be heated efficiently and quickly. At the same time, the heater has high energy consumption, low efficiency and low safety.

At present, a top-mounted infrared electric heating system is newly disclosed (RU Patent No. 126098, IPC F24D10/00, published on March 20, 2013, Bulletin No. 8), wherein the infrared film heater used is based on its similar products. Made of flexible carbon heater elements.

The overhead infrared heating system includes a suspended ceiling comprising an angle profile positioned adjacent to the wall, a support arm with a cross section and a decorative ceiling panel mounted on the ceiling unit, thermal insulation mats, heat reflective film and infrared film in the electric heater. The infrared film electric heater is installed on part of the ceiling board, and its size should not exceed the front size of the ceiling board in the unit. The infrared film electric heater is also equipped with a heat reflection film and a heat insulation pad. Each infrared film electric heater A pin-type plug-and-socket connector is provided, and the wires with the "pin-hole"-type plug-and-socket connector extend on the support frame for connection to the thin-film electric heater.

The infrared thin film electric heater is designed in the form of a flexible carbon electric heater element.

Insulation mat and heat reflective film are integrated with Penofol material.

Infrared heaters are designed as flexible carbon electric heater elements such as: HEAT PLUS (carbon heating film).

The infrared thin film electric heater (infrared heating film) has the following disadvantages:

One is that the direction of action narrows the range of users who cannot be exposed to infrared waves to be continuously heated (at least on the skin), and it also leads to poor heating of objects in the room, which decomposes and releases harmful substances. The air is not heated to the desired degree, so the heater is an inefficient, low-safety and energy-intensive heater.

Due to the above reasons, the infrared thin-film electric heater cannot be used as the main heating device for the heating system of houses, apartments, industrial plants, offices, etc.

Another disadvantage is that since the infrared thin film electric heater is not designed with a continuous carbon layer, but with carbon strips separated from each other, this design cannot maximize the use of the area of the electric heater to improve efficiency, so the efficiency is low. .

The invention relates to providing a novel electric heater with high efficiency, energy saving and safety, the heater at least contains one carbon layer. Due to the novel design, the present invention can generate heat at low cost and reduce the electricity cost of its support. At the same time, the present invention also has the characteristics of simple design and manufacture, easy use, and easy maintenance.

Electric heaters (connectable to the grid) with at least one carbon layer can solve the above problems. According to the scheme, the electric heater includes an infrared heating film and is made of a metal casing, in which a heat reflection layer, a heating layer and a grounding layer are arranged. The heating layer includes one or more infrared heating films, which are made of a continuous carbon heating layer, the heat reflective layer is arranged on one side of the heating layer, and on the other side of the heating layer, the front wall of the heater's metal shell is located on the grounding layer Afterwards, the ground plane is transmissive to infrared radiation.

According to the scheme, the ground layer that can transmit infrared waves is the outer layer of the infrared heating film, or is provided as a separate layer.

According to a solution, the electric heater with at least one carbon layer is provided with a thermostat, such as a remote thermostat.

According to the solution, the housing has a front wall, a rear wall, an upper wall, a lower wall and side walls.

Depending on the solution, the electric heater with at least one carbon layer is fixed to the ceiling and/or the wall, or is installed on the floor.

The features of this technical solution are the basic features of the present invention, and desired technical effects can be achieved by setting, such as: high efficiency, energy saving, high performance coefficient, perfect functions, etc., especially low-cost heat, high heat dissipation and reduced power consumption can be achieved At the same time, the device can be used alone as the main heat source for indoor heating or combined with multiple heaters to form a separate heating system to heat houses, apartments, industrial plants, offices, etc., and provide users with safety guarantees, expand the scope of users, increase amount of users.

In addition, the present invention simplifies the design and manufacturing process, and is convenient, safe and easy to maintain.

The basic features of this solution and the technical effects achieved by this feature are as follows:

In the electric heater with carbon layer, the heating layer includes more than one layer of infrared heating film, the heating layer is arranged in the metal wall of the casing, and the infrared radiation first heats the front wall of the casing, and then heats the remaining walls, thereby effectively Heating the metal effectively dissipates heat and excludes the transmission of infrared radiation through metal parts.

In a room where the heater is installed, as the metal is heated at a high level, the indoor air is also heated efficiently.

The heating of the metal near the infrared heating film will lead to an increase in the coefficient of performance of the heater. Since infrared radiation cannot pass through the metal, it is only necessary to direct the infrared radiation to the metal layer to allow air convection and achieve efficient heat dissipation. Since metal is a barrier to infrared radiation, there is no need to direct infrared light to objects, materials, and users.

Due to the high performance coefficient of the infrared heating film, the high performance coefficient of the infrared irradiation layer as a continuous carbon layer, the high thermal conductivity of the metal, and its safety, these characteristics can produce efficient, safe, high performance coefficient heaters that The device can expand the range of users, increase the safety of use, and will not cause infrared light to irradiate the user and items, and will not cause the user to be overheated or the items will release harmful substances when heated.

Therefore, when creating a heating system suitable for independent private houses or high-rise apartments, factory kitchens, the heater can be used as the main heat source, wherein the heating devices do not need to be connected to each other, and their number and power can be according to the house, apartment or room. designed and installed on any surface, anywhere, for maximum efficiency in heating.

The design and manufacturing process of the heater are simple, for example, the components are simple and easy to obtain, and the size and power are not limited.
