Abstract
The utility model relates to an energy storage type electric heater, comprising a casing whose circumference is constituted by insulation material, storage members arranged in the casing, and electric heating units which extend in the casing and insert in the storage members; pipe line assemblies used for the circulation of heat transfer fluid are arranged around or near the electrical heating units which extend in the casing; when the device stores energy, greater heat energy is stored through melting method, and thus the device is very suitable for storing energy when the power supply is at low valley; the energy is released when the power supply reaches the peak, and thus not only the use-cost can be reduced, but also higher social benefits are realized.
Description
Technical field:
The utility model relates to a kind of energy accumulating electric heater, especially relates to the energy accumulating electric heater that a kind of container for heat exchanger or radiator or other kind provides thermal source.
Background technology:
In electrical network transferring electric power process, when if end user's power consumption is big, the actual electrical that this moment, electrical network transmitted fails to be convened for lack of a quorum greater than the average current of electrical network, this operation period is called as " peak ", and when end user's power consumption hour, the actual electrical that this moment, electrical network transmitted fails to be convened for lack of a quorum less than the average current of electrical network, and this operation period is called as " paddy ".In the paddy period, though power consumption is few, a large amount of electric energy of electrical network self the direct loss of meeting, and the reactive loss of circuit is also relevant with the peak valley extent.In order to alleviate the situation of present power shortage, consider from energy-conservation aspect also that simultaneously the expert proposes carry out the time-of-use tariffs of timesharing, promptly when peak value, adopt higher electricity price, and when valley, adopt lower electricity price.
The electricity heating is both convenient and free of contamination best heating mode, and having as electric heating installation can be in the function of paddy period accumulation of heat, and its use cost can reduce widely, also can reduce the reactive loss of electrical network simultaneously, also has the certain social benefit.Yet, traditional electric heating installation all is that electric energy is directly changed into heat energy, the mode that heats its peripheral air by the heat that this device distributed heats again, its basic structure comprises a radiator or the radiator of liquid is housed, with the resistance wire or the resistor rod that can extend in this radiator, and utilize the direct-fired mode of resistance is realized power conversion.As seen, though the structure of this kind device is simple,, this device directly carries out in conversion process of energy, does not have the function that stores energy, the electricity price in the time of promptly can not utilizing low ebb fully, and can not energy savings.
Chinese patent has proposed a kind of accumulated electric heater No. 2591480, this electric heater adopts one to be installed in carbon fiber electrically backing in the heat-dissipating frame and that be electrically connected with power supply, and the back at the carbon fiber electrically backing adds radiation heat insulation layer and heat-insulation layer successively, at the radiation heat insulation layer thermal storage and energy accumulation piece is installed also simultaneously.Its meaning is to utilize the radiation heat insulation layer to prevent that heat from propagating towards wall direction, and effectively utilizing the energy, and the thermal storage and energy accumulation piece that utilizes the mixture by magnesia and magnesium chloride and oxalic acid to constitute is realized accumulation of heat.Because the thermal storage and energy accumulation piece of this kind structure can only discharge its energy when being heated by electric heating piece or after being heated again, it can not store bigger energy, so this electric heater does not have accumulation of heat when low ebb, and when peak value the function of heat release.
Summary of the invention:
Task of the present utility model provides the energy accumulating electric heater that a kind of mode of utilizing peak load shifting is saved the electric cost and the energy.
The energy accumulating electric heater that the utility model proposed, comprise that periphery is by insulation material housing that constitutes and the accumulation of energy parts that are arranged in this housing, and extend in the housing and insert electric heating unit in the accumulation of energy parts, and the periphery of the electric heating unit in extending into housing or near be provided with the pipeline assembly that is used for the heat-transfer fluid circulation.
Described pipeline assembly is wrapped in the periphery of electric heating unit at interval preset distance, and make the two ends of pipeline assembly extend housing and extend into heat exchanger or radiator in.The port of export at pipeline assembly also is equipped with fluid buffer.
Described accumulation of energy parts are made of lead, and make lead be full of the interior whole space of housing.
Described electric heating unit has two pipe fittings that extend in the housing, and is inserted with resistance or resistance wire in each root pipe fitting, and this resistance or resistance wire extend housing parts and be connected with cyclelog.Described cyclelog also is provided with three control ends, wherein two control ends respectively be installed in heat exchanger or radiator in and temperature sensor in the accumulation of energy parts be electrically connected, another control end is electrically connected with magnetic valve on being installed in pipeline assembly.
The accumulation of energy parts that the energy accumulating electric heater that the utility model proposed adopts are plumbous or its similar articles, when accumulation of energy, lead can melt, and its be heated until the fusing whole process in need very big energy, so this device can store very big energy, and when releasing energy, since plumbous in liquid state gradually in solid-state conversion process, under the situation that does not have heat to scatter and disappear, stored energy all can be discharged.As with this device in power supply accumulation of energy during low ebb, and when the power supply peak value, release energy, not only can reduce use cost, but also electric energy can make full use of low ebb the time has high social.
Description of drawings:
Accompanying drawing 1 is the surface structure schematic diagram of an embodiment of energy accumulating electric heater;
Accompanying drawing 2 is surface structure schematic diagrames of another embodiment of energy accumulating electric heater.
The specific embodiment:
