Description
The utility model relates to the electric heating device that a kind of warming is used, and especially a kind of forced convertion, employing are the electric heater of the electric heating panel of core material as heating with the carbon fiber, belong to the electric-heating technology field.
Existing with the electric heater of quartzy tubular electrothermal element as thermal source, be that resistance wire is arranged in the quartz ampoule, by imposing voltage, and convert electrical energy into heat energy at the resistance wire two ends, by reflector the heat energy reflection is added hot-air again, reach the purpose of warming.This warmer floor space is big, and electric conversion rate is low, heating surface temperature height, poor stability.
The existing electric heater that is referred to as electric heating installation using oil as medium is by the conduction oil of tubular metal heating heated sealant in cavity or the material of water, heat is passed to the fin on the shell cavity and air heat is reached the purpose of heating.This electric heater complex structure, thermal inertia is big, and the thermal efficiency is undesirable, and the temperature field is inhomogeneous, and energy consumption is many, the manufacturing cost height.
Above-mentioned electric heater consumes energy is many, and result of use is undesirable, security performance is not good enough, price is high, has brought inconvenience to the user.
Existing heating plate electric heater, because it only relies on Natural Heat Convection, radiating effect is poor, indoor temperature rises slowly, the speed that heating plate heat in the electric heater housing produces is greater than the speed of heat radiation, too high and the very easily carbonization blackening of the glass fabric Yin Wendu that makes heating plate inside, influence the life-span of heating plate, heating plate in the electric heater housing and electric heater two heat dissipation metal Shell Plates tightly paste and are one, once after heating plate uses a period of time, the film that heater plate surface is used as insulation because of constantly be subjected to the heat ageing edge extremely grade reduce, then can make heat dissipation metal Shell Plate failure of insulation, and the generation electric shock accidents, thereby security is unreliable.
The purpose of this utility model provides a kind of novel forced convertion far infrared electric heater, and it is simple in structure, the electric conversion efficiency height, energy-saving effect is remarkable, and the temperature field of heating service is even, and security is good, long service life has the health-care physiotherapeutic function to human body in heating.
The utility model is achieved through the following technical solutions: forced convertion far infrared electric heater mainly is that heating board and the blower fan by electric heater housing and conductive exothermal constituted.Electric heating panel is superimposed successively hot-forming by insulation film, epoxy glass cloth, carbon fibre composite paper (or carbon fiber compound nonwoven cloth), epoxy glass cloth, insulation film, or electric heating panel is superimposed successively hot-forming by micarex, carbon fibre composite paper (or carbon fiber compound nonwoven cloth), micarex.Electric heating panel is located in the electric heater housing, does not contact with two heat dissipation metal Shell Plate faces of electric heater housing, and blower fan is located at the electric heater lower part of frame.The lower shoe of electric heater housing and upper cover plate are packing less.The electric heater housing is provided with switch and temperature controller.When opening switch, connection power supply, electric heating panel convert electrical energy into heat energy, the blower fan air draught blows out the heat forced convertion from the hot-blast outlet on the upper cover plate, the heat that convection current blows out is not able to do in time, pass to two heat dissipation metal Shell Plates of electric heater housing and conduct by the electric heating panel radiation and add hot-air, reach the purpose of heating.
Electric heating panel is even as heating thereby heating, electric conversion efficiency is high (reaching more than 97% in the actual use) owing to using in the above-mentioned solution, and has a function far infrared radiation function, power savings is remarkable, service life, dielectric strength height, surface temperature automatic constant were middle low temperature above 3-5 times of resistance wire, security is good, since adopt the blower fan blowing to force the heat convection current, good heat dissipation effect, and indoor heating-up temperature rising is fast, the temperature field is even.Because the heating plate in the electric heater housing separates with electric heater housing two heat dissipation metal Shell Plates, can not produce heat dissipation metal Shell Plate failure of insulation phenomenon, guaranteed that the user's is reliable and secure.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the basic structure of the utility model forced convertion far infrared electric heater.
Fig. 2 is the A-A cutaway view among Fig. 1
