Abstract

The utility model relates to a domestic super-thin electric warmer, providing a super-thin mural painting type electrical warmer which uses a PTCR electric heating element as the heating source and is controlled by a special electric control and provided with a heat radiating fin and a heat conducting plate. Therefore, the effects of low power consumption, space saving, high efficiency and low cost are achieved. Using the PTCR electric heating element, the electricity can be saved by 30%. Using the customed designed electric control, the moment supply current is reduced; the actual use of the PTCR electric heating element is satisfied.

Description

Super-thin electric warmer

The utility model relates to a kind of civilian electric heater.

At present a lot of families or departments such as office, school are not having under the central heating facility condition, use some electric heating or oil, the hot warmer of gas, and its version, heat form are had nothing in common with each other, wherein especially with the warming installation of energy-conservation, low consumption more people liked.Aspect electric heating, comparatively in vogue is many with far infrared quartz glass tube and oil immersed type electric heater recently.The former can economize on electricity about 20%, but cracky, give to install and use and make troubles, and need be furnished with annex such as fan, during use under the blowing of wind the unusual drying of air, be not suitable for long-term use.The oil immersed type electric heater generally stands up indoor, relatively takes up an area of, and maximum deficiency is to cause leakage of oil easily, and power consumption is bigger.

The purpose of this utility model is: provide a kind of PTCR of utilization electrothermal piece to do pyrotoxin, by special-purpose electrical control member control, and be furnished with the ultra-thin wall painting type electric heater that parts such as fin and heat-conducting plate are formed, thereby reach the reduction power consumption, save space, the height low result of use of tiring.

The purpose of this utility model realizes by following technical measures:

It includes heat sink, fin, battery lead plate and PTCR heating element heater, between heat sink and the fiberboard; Bolt screws on heat sink, and end is screwed on heat-conducting plate and the battery lead plate and further fin is fixed in addition, and screw is tightened on the heat-conducting plate, in addition in the end screw-in ceramic flange, with fixing PTCR heating element heater; Clamping has mica sheet between heat-conducting plate and battery lead plate, is furnished with the PTCR heating element heater between battery lead plate and fin uniformly; Be covered with one deck masking foil on the cover plate of the relative rear portion of the opening of its fin.Back shroud is that idioelectric insulating materials is made; Upper and lower end face at electric heater is furnished with thermovent respectively; Monoblock heat sink and bonnet cover by the front and back framework and are case structure.Can spray, draw multiple scenery with hills and waters, figure picture on the heat sink.

Advantage of the present utility model and effect are:

1, adopt the PTCR heating can reach economize on electricity 30%.

2, adopt custom-designed electrical control member, make moment supply current reduction, satisfied the actual use of High-Power PTC R electrothermal piece.

3, structural design has new meaning, and thickness reduces, and can be used as mural painting and hangs on the indoor wall.

4, security performance is good, can the auto-control temperature.

Description of drawings is as follows:

Fig. 1 is the utility model front front view;

Fig. 2 is a vertical view of the present utility model;

Fig. 3 looks sectional view for an A-A of the present utility model left side.

Below in conjunction with accompanying drawing embodiment of the present utility model is described further:

Whole electric heater is tabular, and thickness is greatly about 50 millimeter, and heat transfer area of dress fin 3 is similar with general oil immersed type electric heater in it, in naturally up and down under the convection action of air, passes to indoor by louvre 10 heat.On the other hand the heat that sends of PTCR heating element heater 11 directly conduction pass to heat sink 1 to indoor distribute heat for battery lead plate 7 and heat-conducting plate 8, the outer surface of this heat sink 1 can not be too warm, in order to avoid scald the people, therefore between battery lead plate 7 and heat-conducting plate 8, press from both sides one deck mica sheet 9, both played insulating effect, played the effect of thermal resistance again, made the outer surface of heat sink 1, touch unlikely scalding one's hand with hand, certain heat transmission is arranged again.Its fin 3 can adopt aluminium sheet processing, vertically arranges several groups of finned fin 3.On the back shroud 2 of corresponding fin opening, can bonding one deck masking foil 6, so that the heat that fin sheds produces the effect of refraction by masking foil 6, back shroud 2 can be made by fiberboard or glued board etc., be fastened on the afterframe 4 by screw, side plate can be converted into L shaped as front baffle 5 by steel plate, and heat sink 1 is fixed in the above.Its bolt 12 is used for fixing fin 3, it can be welded in the inner surface of heat sink 1, also can directly pass heat sink 1 and be fixed together with fin 3.PTCR heating element heater 11 is clamped between fin 3 and the battery lead plate 7, fastening by screw 13 then, for preventing the electric current conduction, be combined with the ceramic flange 14 of insulation at an end of screw 13, its control original paper is fixed on the appropriate location and carries out conducting by battery lead plate 7, when 11 momentary connections of PTCR heating element heater, it is unlikely excessive effectively to control its electric current, and keeps temperature maintenance in a certain amount of scope.This electric heater electrical power is between 500-1000 kilowatt, and transmission area is transmitted heat and generally the oil immersed type electric heater is similar, and its electric energy is higher.

Claims

1, ultra-thin electric heater includes heat sink 1, fin 3, battery lead plate 7 and PTCR heating element heater 11, it is characterized in that between heat sink 1 and the fiberboard 2; Bolt 12 screws on heat sink 1, and end is screwed on heat-conducting plate 8 and the battery lead plate 7 further that fin 3 is fixingly in addition, and screw 13 is tightened on the heat-conducting plate 8, and end screws in the ceramic flange 14 in addition, with fixing PTCR heating element heater 11; Clamping has mica sheet 9 between heat-conducting plate 8 and battery lead plate 7, is furnished with PTCR heating element heater 11 uniformly between battery lead plate 7 and fin 3; Be covered with one deck masking foil 6 on the relative rear portion of the opening of its fin 3 cover plate 2.

2, electric heater as claimed in claim 1 is characterized in that back shroud 2 makes for idioelectric insulating materials; Upper and lower end face at electric heater is furnished with thermovent 10 respectively; Monoblock heat sink 8 covers by the front and back framework with bonnet 2 and is case structure.
