Electric heat sink is a kind of energy, which can be directly converted into heat energy, and through the temperature controller to achieve the heating and cooling equipment of the radiator, the radiator is fixed in the building. Electric heating radiator species complex, diverse and sum up can be according to the heat, heat transfer type and installation form to carry on the classification, the electrical heating radiator according to the heat release can be divided into direct acting and regenerative; according to the type of heat transfer can be divided into convection and radiation, the convection including natural convection and forced convection two; according to the installation of the form can be divided into lifting type, wall and floor type.

Direct acting type electric heating radiator is in the building needs heating, the electric energy into heat energy, and heat energy directly to the building of electric heating radiator. The heat storage type electric heating radiator is a heat storage medium which is converted into heat energy through the heat storage medium, and the electric heating radiator of the heat energy stored in the building is needed. Convection type electric heating radiator, air in a radiator formed circulation channel, and arrangement of the air inlet and outlet grille, which is also different from convection on the radiation characteristics, natural convection through the hot air natural spread upward, cold air natural downward diffusion convection heat, forced convection generally by means of wind machine to realize air convection heat transfer.

Comparison with other electric heating methods

At present, the market of electric heating methods mainly have the following several: electric heating boiler, electrothermal film, electric cable, electric heater, electric heating radiator. 1) electrothermal film: this kind of heating way occupy the three-dimensional space of the building, the installation space is relatively large, it is not easy to subscribers decoration, poor comfort, hot air in, is easy to produce thermal head cold feet, and cannot use occasions in damp; 2) electric cable: this kind of heating way also occupied the three-dimensional space of the buildings and materials and arrangement of furniture, flooring, have special requirements, heat up for a long time, temperature and the reaction speed is slow, resulting in comprehensive high operating costs, the higher the construction process requirements, cost is on the high side. Electric cable is usually used in the heating system or snowmelt. 3) electric boiler: the pipeline system is complex, the construction requirements are high, the middle of the medium (hot water) inevitably caused by heat loss, not easy to carry out the adjustment of the chamber. Compared with other electric heating equipment, the heat storage capacity of the system is larger, but it does not have the ability to regulate and control, the heating comfort is low, operation and maintenance cost is high. 4) electric heater: come in all shapes and sizes, oil heater, infrared radiation electric fans, vacuum heat pipe forms, as home appliances products, is not fixed in the building, not according to the requirements of building heating load and the selection of, control performance is relatively simple. 5) the electric heating: the direct heating of air, fast heating speed, diverse forms; adopts the advanced control technology. It can not only accomplish cent door control, and can achieve the room partition control, can be in accordance with the comfortable degree of need and no antifreeze and other requirements control room temperature; installation requirements is not high, widely used in civil and industrial fields. The electric heating characteristics of the main features are: radiator equipment maintenance; installation and disassembly and easy operation; direct heating of indoor air, no medium heat conversion rate is 100%, the efficiency is high; the control system can guarantee the room temperature according to the requirements of rapid response, if the temperature is higher than the set temperature, the radiator automatically shut down, if the temperature drops below the set temperature. The radiator automatically start to ensure high comfort at the same time, but also to ensure that electricity is not wasted; not need to produce energy and set up a special equipment .
