Description
The utility model relates to a kind of electric heating device.
Electric heater can be divided into according to radiating mode: far infrared radiation formula, forced convection heat dissipation type and Natural Heat Convection formula.Existing is that the electric heater of main heat radiation form has two classes with free convection: 1. with liquid medium conduct heat, the electric heater of heat accumulation.Liquid medium around the heat that the heating of such electric heater sends is at first passed to is transmitted to heat sink to heat by liquid medium and distributes.Because low two orders of magnitude of the thermal conductivity factor of the thermal conductivity ratio metal material of fluent material, thereby electric heater has bigger thermal inertia.It is similar to the heat-transfer character of hot-water radiator, and surface temperature is not too high, also can continue distribute heat in a period of time after the outage.But the liquid medium material that such electric heater is commonly used is a mineral oil, because of oil accident easily takes place reasons such as airtight quality, and explosion danger is arranged.In addition, energising back programming rate is also slower.2. the plate electric heater that does not have heat-storage medium.The heat that the heating of such electric heater sends is directly transferred to heat sink and distributes, and thermal inertia is little, energising back quick heating, and surface temperature is high than the former.Such electric heater integral thickness is thinner, and weight is lighter, is easy to move, and does not have medium leakage problems and explosion danger.Weak point is that the cooling of outage back is too fast.The heater element of this two classes electric heater is the electrothermal alloy element.Though naked light be cannot see in the outside after encapsulation, inner heating wire is in red vehement state when work, easily oxidation of surface, and the life-span is shorter, and security reliability is poor.
The purpose of this utility model is intended to solve the some shortcomings part of above-mentioned existing electric heater, provide a kind of do not have medium seepage, no combustion explosion danger, security reliability high, with the electric heater of solid material as heat-storage medium.
Realize that the purpose of this utility model technical scheme is such.This electric heater comprises metallic heat radiating plate, insulating barrier, outer metal heat-conducting plate, heating, interior metal heat-conducting plate and solid heat-storage medium.Heating adopts sheet PTC heating, and it is installed between the inside and outside metal heat-conducting plate, between outer metal heat-conducting plate and the metallic heat radiating plate insulating barrier is arranged, and solid heat-storage medium and interior metal heat-conducting plate are installed together.Respectively connect a lead on the inside and outside metal heat-conducting plate, lead is connected with attaching plug.The solid heat-storage medium is at high temperature chemical property and physical property inorganic non-metal solid material stable, that high thermal conductivity and specific heat are arranged.The heat that heating sends is simultaneously to inside and outside metal heat-conducting plate conduction.The heat that is transmitted to outer metal heat-conducting plate distributes to the external world through heat sink by behind the insulating barrier; The heat of metal heat-conducting plate then enters the solid heat-storage medium in being transmitted to.
The utlity model has following advantage:
1. the utility model adopts the inorganic non-metal solid material that high thermal conductivity and specific heat are arranged as heat-storage medium, compares with the electric heater of liquid heat-storage medium, does not have medium seepage and explosion danger, and energising back quick heating, thermal inertia are little; Compare with the electric heater of no heat-storage medium, the heat that stores up in the heat-storage medium of outage back slowly discharges, and makes electric heater continue heat radiation in a period of time, and bigger thermal inertia is arranged.
2. heating of the present utility model is a sheet PTC heating.This element is made with semiconductor ceramic material, flames of anger during work, and temperature rise is fast, and the life-span is long, the security reliability height.The volt-ampere characteristic of PTC element is non-linear, thereby its caloric value is subjected to the influence of mains fluctuations hardly, and can regulate its caloric value automatically with the environment temperature height.
3. the utility model does not need temperature adjustment, temp-controlling element, can use continuously for a long time.
4. the utility model is easy to make water proof type, can be placed in comparatively moist Household bathroom, the toilet to use.
Embodiment of the present utility model is illustrated in conjunction with the accompanying drawings.
Fig. 1 is a structural principle schematic diagram of the present utility model.
Fig. 2 is a single side structural representation of the present utility model.
Fig. 3 is the A-A face cutaway view of Fig. 2.
Fig. 4 is a double-side type structural representation of the present utility model.
Among the figure, 1-metallic heat radiating plate, 2-insulating barrier, the outer metal heat-conducting plate of 3-, metal heat-conducting plate in the 4-heating, 5-, 6-solid heat-storage medium, 7-attaching plug, 8-lead, 9-leg.
From Fig. 1, Fig. 2, Fig. 3 as can be seen, heating＜4〉is installed between interior metal heat-conducting plate＜5〉and the outer metal heat-conducting plate＜3 〉, be connected with lead＜8〉on the inside and outside metal heat-conducting plate, lead＜8〉links to each other with attaching plug＜7 〉, and solid heat-storage medium＜6〉is installed together with interior metal heat-conducting plate＜5 〉.Under its base plate of housing with the metallic heat radiating plate formation leg is housed.The solid heat-storage medium is at high temperature chemical property and physical property inorganic non-metal solid material stable, that high thermal conductivity and specific heat are arranged, as with raw material machine-shapings such as gypsum, sand, clay, cement, lime.Heating is a sheet PTC heating.The materials such as magnetic or mica of warding off of insulating barrier available energy withstand higher temperatures constitute.The insulating barrier of single side structure of the present utility model＜2〉metallic heat radiating plate＜1〉and outside between metal heat-conducting plate＜3〉and the solid heat-storage medium＜6 〉.The power of sheet PTC heating is lower, is example with MZ95 type PTC element, and the heating power of a slice PTC element is between 40～60W, and the electric heater that power is 500W needs 8～10 PTC heatings.The single side electric heater can be placed on by the position of wall and use.
Double-side type structural principle of the present utility model as shown in Figure 4 is with shown in Figure 1, the difference of its structure and single side just in solid heat-storage medium opposite side has increased by a cover metal heat-conducting plate＜5 〉, heating＜4〉and outside the structure of metal heat-conducting plate＜3 〉.The double-side type electric heater is not suitable for being placed on and uses by the position of wall.
