The utility model is based on two sections of control type metal PTC electric heaters of post cabinet air-conditioner, using with compared with Gao Zhengwen
The metal PTC B alloy wire of coefficient is spent as heater element, and metal PTC thermistor alloy silk has advantage following prominent:1st, heat
Speed is fast, and heating element heater is to calculate resistance value by the operating temperature used.In room temperature, resistance value is small, after energization within the several seconds
Heater element surface can reach design temperature.2nd, electric energy is saved, due to being raised with temperature, power drop, to certain temperature not
Rise is may proceed to, energy-conservation purpose is reached.3rd, long lifespan, also due to automatic control effect, the unexpected rise of operating voltage, or meaning
Temperature caused by outer blowing-out is raised, and is all incited somebody to action and is drawn power drop, effectively controlled cause thermal damage.4th, performance is stable, is used for a long time
Prove, resistivity and temperature-coefficient of electrical resistance are constant.It will not produce aging as ceramic PTC.It is small up to 1000 between when deployed
When, ceramic PTC power attenuation is up to 10%, under similarity condition, and it is only 1% that metal PTC electric heater capacity, which declines,.Due to metal
PTC has stronger temperature automatic adjustment function.Under the conditions of air-supply, when adjusting heating power with air quantity, sensitivity is high, therefore special
It Shi He not worked under the low speed flow of air conditioner.Metal PTC does not have as thermo electric material of new generation with other thermo electric materials
Standby characteristic.First, it is more much smaller than the temperature-coefficient of electrical resistance of ceramic PTC.This makes it but also with another advantage, in initial heating
In the stage, as temperature is raised, heating power is declined by given pace, but not is dropped suddenly as ceramic PTC, may cause heating
Underpower.And the fall off rate of metal PTC is slower, so as to ensure stablizing the heating period, there are enough heating powers.Due to
Metal PTC cold-state resistance is small, and initial current is big, and quick high-power heating makes air conditioner carry out heating shape rapidly, compensate for air-conditioning
Machine, which starts, heats this big deficiency of inertia.In addition, metal PTC electric heater air port heating efficiency is 96.4%, significantly larger than make pottery
Porcelain PTC air ports heating efficiency is 76.5%, and the effect for more easily reacing energy-conservation is used for a long time.
The utility model employs hardware and software platform design, the insulating mounting of two high-temperature stability of metal PTC electric heater
Support, the insulating mounting support Design of head leading-out terminal automatic sliding structure, effectively prevent metal PTC electric heater body
The bending produced in normal work because expanding with heat and contract with cold;Tails position is sealed using the both arms heat-shrink tube with glue
And insulation, it is nonpoisonous and tasteless.Heater uses insulation, resistant to elevated temperatures modified magnesium powder as packing material, and electrical heating body is not
It is powered;Fin is that 1060 fine aluminiums are formed through continuous closing mould stretching, fin can effectively increasing heat radiation area, improve heat-transfer effect
Such as:Evaporator, condenser, are conducive to large-scale production.
The utility model has two groups of power outputs, the characteristics of carrying out 3 grades of control.The power of two groups of outputs is respectively:
600W and 1500W.3 grades of power brackets controlled are:1 grade~600W, 2 grades~1500W and 3 grade~2100W, user can basis
Need, any one grade of power output in 3 gears of sets itself.
In terms of security performance, metal PTC material has heating power automatic regulation function, and limit temperature further rises
Height, prevented thermally-induced failure and accident.In order to further improve safety coefficient, on the heaters equipped with two class protection element,
The first order is bi-metal temperature controller, and the second level is thermal fuse-link.It so can effectively prevent the generation of the accidents such as fire.
The beneficial effects of the utility model are:
In terms of the utility model not only has the advantages that fast firing rate, saving electric energy, long lifespan and performance are stablized,
But also heat-transfer effect can be improved, be conducive to large-scale production, and with good security performance, prevented thermally-induced failure
And accident.
