Description
Technical field
The utility model belongs to the warmer technical field, particularly the structural design of accumulating type warmer.
Background technology
In recent years, environmental pollution is serious day by day.In the winter time, the dust and the discharge of harmful gases that cause in coal heating of the main pollution source in northern China city.New pollution-free or oligosaprobic heating heating mode is badly in need of releasing in society.Thereby the employing electric heating, more and more be subjected to people's favor as electric heating oil lamp, electrothermal quartz tube warmer, electric heating devitrified glass radiation warmer etc.But, in China and even world wide, all there is the peak-valley difference problems of too of power supply network, seriously hindered the reasonable use of electric power, also hindered effective development of electric heating device simultaneously.Because using the time of this type of warmer mostly is when the overall grid load reaches peak value, necessary and heating time synchronized of electrical heating time, thereby can aggravate the excessive problem of power network load peak-valley difference more.
Summary of the invention
Goal of the invention of the present utility model is in order to solve environmental pollution and the excessive problem of power supply network peak-valley difference, to remedy the deficiencies in the prior art, a kind of middle temp phase-change energy-accumulating heating device being provided.It can utilize the electricity of electrical network low ebb phase to make warmer heating, accumulation of heat, uses big rate of heat release that the heat of savings is emitted to keep indoor temperature when the electrical network peak period needs heat supply.
Temp phase-change energy-accumulating heating device among the utility model design a kind of is characterized in that comprising: a heat-insulation layer housing, be respectively equipped with air inlet, shutter on this heat-insulation layer shell two side, and air outlet, go out air door; Heat-insulation layer is built-in with heat exchange box, and the heat exchange box outer surface is equipped with the enhanced heat exchange fin; Heat exchange box inside is filled with heat transferring medium; Heat transferring medium is built-in with bracing frame, the bracing frame support with separate a plurality of variodensers mutually and temperature control heater, be sealed with phase-change material in the phase variodenser; This air outlet place is provided with ventilation fan; One time controller with go out air door and the chain interaction of temperature control heater.
Said time controller can adopt and be solidified with time control procedure time controller.
Said temperature control heater comprises heating element heater and temperature controller, and wherein heating element heater adopts a kind of of ceramic electrical hot pin, resistance wire, electrothermal tube or Electric radiant Heating Film.
Said phase-change material can adopt Nitrates or hydroxide, and its phase transition temperature is between 70 ℃ ~ 90 ℃.
It is the accumulation of energy medium that the utility model adopts with the phase-change material, makes the phase-change material accumulation of energy earlier by electric heater unit, then the heat that holds is emitted.So just can utilize the electricity of power supply network low ebb phase at night to make warmer heating, accumulation of heat, to heat release heating during the power supply network peak period on daytime.Thereby the peak-valley difference of not only adjustable economize on electricity net load, and after adopting the electricity price peak valley phase to divide valency meter system, can save operating cost.Compare with prior art, the utility model is environmentally safe not only, and can fundamentally solve the problem of power supply network peak-valley difference.Have characteristics reasonable in design, simple in structure, easy to use, dependable performance, the bright prospects of exploiting market are arranged.
Description of drawings
Fig. 1 is an embodiment general structure schematic diagram of the present utility model.
The specific embodiment
The example structure of a kind of middle temp phase-change energy-accumulating heating device of the utility model design is described in detail as follows in conjunction with figure as shown in Figure 1:
Present embodiment comprises with lower member: heat-insulation layer housing 1, heat exchange box 2, water 9, enhanced heat exchange fin 3, bracing frame 4, temperature control heater 5, time controller 8, ventilation fan 10, phase variodenser 13, phase-change material 14, air inlet 6, shutter 7, air outlet 11, go out air door 12.
Each parts thing annexation is: heat-insulation layer housing 1 is made by foamed plastics; Heat-insulation layer housing 1 is provided with air inlet 6, air outlet 11, shutter 7, goes out air door 12; Heat-insulation layer housing 1 is built-in with heat exchange box 2.Heat exchange box 2 is iron wares; Heat exchange box 2 outer surfaces are welded with enhanced heat exchange fin 3; Heat exchange box 2 inner filling waters 9.Water 9 is built-in with 7 the phase variodenser 13 and the temperature control heaters 5 that are sealed with phase-change material 14, and wherein bracing frame 4 plays a part to separate and supports variodenser 15 mutually.Phase variodenser 13 is stainless steel container mades.Phase-change material 14 adopts NaOH, and its phase transition temperature is at 70 ℃.Temperature control heater 5 is made up of electrothermal tube and temperature controller, and this two elements is outsourcing.Air outlet 11 places are provided with ventilation fan 10.Time controller 8 with go out air door 12 and the 5 chain interactions of temperature control heater; Time controller 8 adopts and has solidified time control procedure time controller, also is outsourcing.
Present embodiment operation principle and process are:
When using present embodiment, regularly start the night that time controller 8 was solidificated in the electrical network low ebb phase, can economize like this and use the peak electricity, makes full use of paddy; Go out air door 12 simultaneously and shutter 7 is closed.After temperature control heater 5 was connected power supply, the water 9 in the heat exchange box 2 began to heat up and heat is passed to phase-change material 14.Phase-change material 14 begins to undergo phase transition after temperature arrives critical-temperature.When phase-change material 14 melted fully, temperature control heater 5 stopped heating.At this moment heat is mainly stored in the latent heat mode by phase-change material 14.In indoor need the heating, open out air door 12 and shutter 7 and make warmer begin external heat release.Liquid phase-change material 14 solidifies gradually, emits heat of solidification simultaneously.
In order to make air and heat exchange box 2 heat exchange abundant, by technique scheme, air inlet 6 and air outlet 11 on described heat-insulation layer housing 1 wall are located at the heteropleural surface.
Because the approximate constant temperature process of phase transition process, latent heat of phase change is bigger, so even also can be similar to the isothermal heat release long period under cold situation.
The technical scheme of the foregoing description is explanation as an example only, can not limit protection domain of the present utility model, as if the equivalent transformation that the technical scheme of embodiment is made, all belongs to the protection domain of claim of the present utility model.
