The heating equipment mainly consists of the phase change materials and electric heating film heating materials, wherein an electric heating film heating device is an electric heating device, the phase change materials are energy storage materials and are in a solid state at normal temperature, the electric heating film heating materials simultaneously heat the phase change materials during heat generation heating, the phase change materials are converted into liquid state from the solid state, a large amount of heat energy is stored, a power supply of the electric heater is switched off, the whole machine temperature of the electric heater starts to drop, when the temperature drops to the phase change point, the phase change materials start to carry out phase change and are converted into the solid state from the liquid state, a large amount of adsorbed heat energy is released, the goal of using the phase change materials for continuous heating is realized, and the continuous heating is realized through once startup.
Description
Technical field
The utility model relates to a kind of heating equipment, especially a kind ofly is used for civilian electric heater equipment.
Background technology
In recent years, the electric heater product relies on that its structure is light and handy, advantages such as price is low, heat supply efficiency is high, cleanliness without any pollution are subjected to consumer's favor deeply.
Yet along with global energy shortage situation occurs, it also is inevitable that energy-saving and emission-reduction work enters family; At present, electric heater mainly is divided into quartz ampoule warmer, heating wire warmer, warm-air drier formula warmer, oil medium type warmer, electrothermal membrane type warmer etc.
Present electric heater is quick-heating type substantially, and it is very fast to heat up, but waste heat is also short, close electric heater after, can cool down very soon in the room, thermal source can not be provided for a long time, and open electric heater for a long time, have very big unsafe factor again.
Summary of the invention
Stable thermal source in order to provide long the time, the utility model provides a kind of new solution equipment, under the powered-down situation, continues to provide heat.
Described utility model is a kind of heating equipment that uses phase-change material, and common electrical warmer characteristics are promptly arranged, and long-acting heating characteristics are also arranged.Described utility model is the combination of Electric radiant Heating Film warmer and phase-change material, and the Electric radiant Heating Film warmer in the described utility model is an electric heating device, and phase-change material is for having energy storage material.
Phase-change material (PCM-Phase Change Material) is meant and varies with temperature and change form and the material of latent heat can be provided, phase-change material is by the solid-state liquid state that becomes, or become solid-state process by liquid state and be called phase transition process, at this moment phase-change material will absorb or discharge a large amount of latent heat; Phase-change material can be divided into organic (Organic) and inorganic (Inorganic) phase-change material, also can be divided into hydration (Hydrated) phase-change material and wax (Paraffin Wax) phase-change material; Modal phase-change material is a water, and when temperature was low to moderate 0 ℃, water was become solid-state by liquid state, discharged a large amount of heats, and when temperature was higher than 0 ℃, water absorbed a large amount of heats by the solid-state liquid state that becomes; Utilize this principle of phase-change material, utilize solid-liquid to change, lasting heating process can be provided.
Described utility model is similar to the common electrical warmer, and main body is flat molding box body, and phase-change material is installed in casing, and at normal temperatures, phase-change material is solid-state; The Electric radiant Heating Film exothermic material is installed outside casing, the Electric radiant Heating Film exothermic material is when the heating heating, heat to phase-change material simultaneously, when the temperature of the complete machine of electric heater rises to the transformation temperature of phase-change material, phase-change material begins phase transformation, from solid state change is liquid, phase transition process excessively in, phase-change material has stored a large amount of thermal energy; Close the electric heater power supply, the Electric radiant Heating Film exothermic material no longer generates heat, the complete machine temperature of electric heater begins to descend, when the temperature of the complete machine of electric heater drops to the transformation temperature of phase-change material, phase-change material begins phase transformation, changes into solid-stately from liquid state, discharges a large amount of thermal energy that absorbed, the temperature of keeping in the room that needs heating does not reduce, and has realized utilizing phase-change material to continue heating.
Common relatively electric heater, described utility model have long-acting heating characteristics, and once start continues heating.Because present energy shortage situation, the electricity charge rate modes again that adopt more, described utility model adopts peak, paddy, flat charging way, so can adopt accumulation of heat when cheap rate, when peak of power consumption, not power consumption continues heating, realizes saving electricity charge spending, regulated the peak valley flat structure of power consumption, for contribution has been made in energy-saving and emission-reduction.
Described utility model except that be applied to civilian, also can be applied to other industrial heating situations.
Description of drawings
Fig. 1 is described utility model system architecture schematic diagram.
The specific embodiment
As shown in Figure 1, described utility model is made up of electric heater casing 1, Electric radiant Heating Film exothermic material 2, phase-change material 3; Described utility model electric heater casing 1 is flat molding box body, and is approximate with common oil medium type warmer profile, and phase-change material 3 is installed in casing 1, and Electric radiant Heating Film exothermic material 2 is installed outside casing 1, and the Electric radiant Heating Film model of using in this example is: KH210; Phase-change material 3 tabular profiles, shell is plastics, is sealed with the hydration phase-change material in the shell, if be installed in the casing 1 in the tabular phase-change material 3 of quantity.
At normal temperatures, phase-change material 3 is solid-state, Electric radiant Heating Film exothermic material 2 is when powering up the heating heating, give phase-change material 3 heating simultaneously, when the temperature of the complete machine of electric heater rose to the transformation temperature of phase-change material, phase-change material began phase transformation, was liquid from solid state change, phase transition process excessively in, phase-change material has stored a large amount of thermal energy; When closing the electric heater power supply, Electric radiant Heating Film exothermic material 2 no longer generates heat, the complete machine temperature of electric heater begins to descend, and when the temperature of the complete machine of electric heater dropped to the transformation temperature of phase-change material, phase-change material began phase transformation, change into solid-state from liquid state, discharge a large amount of thermal energy that absorbed, the temperature of keeping in the room does not reduce, in this example, phase-change material 3 can be kept heating more than 4～8 hours, had realized utilizing phase-change material to continue heating.
Other belong to known technology, no longer narration as the temperature control device etc.
This example adopts in the flat difference of peak valley of utilizing the multiple rate electricity charge, the every day of accumulation of heat when hanging down the electricity charge, and heat release when the high electricity charge realizes saving electricity charge spending, has regulated the peak valley flat structure of power supply.
