Abstract
The invention discloses a safe energy-saving type full-automatic dampproof damp-clearing heating plate which comprises a bottom plate, a radiating sheet plate and a PTC ceramic plate. A boss is arranged on the upper surface of the bottom plate. A concave groove is formed in the lower surface of the radiating sheet plate. The radiating sheet plate is arranged above the bottom plate through a bolt. The boss is matched in the concave groove. The radiating sheet plate is provided with extending parts on the two sides of the bottom plate. The PTC ceramic plate is fixed above the boss of the bottom plate through a silica gel belt. According to the safe energy-saving type full-automatic dampproof damp-clearing heating plate, the phenomenon that moisture condensation happens to a high-voltage cabinet can be avoided, the constitution of a heating system is greatly simplified, cost is lowered, heating is quick, and the critical defect that when a temperature-humidity controller controls an electric heating wire heating plate, service life is short, and reliability is poor can be avoided.
Description
Technical field
The invention discloses a kind of heating plate, particularly the full-automatic moistureproof clearing damp heating plate of a kind of safety and energy-saving.
Background technology
The life-span of heater depends primarily on the core material nichrome heating wire of electric heater, and the antioxygenic property when high temperature is the important indicator in heater life-span.Under normal circumstances the surface of electrothermal alloy element must have one deck densification uniformly with parent metal in conjunction with oxide-film firmly; its existence can slow down oxygen atom to the seepage velocity of metal inside; slow down the seepage velocity of other etchant gases simultaneously, thereby play a protective role.But practical application Zhong Ge manufacturer does not carry out the mensuration of electrothermal alloy oxidation rate, but use instead, detect its quick life-span, with this, characterize the non-oxidizability of alloy.
Present stage, the domestic heating wire life-span is 2000 hours, namely less than 3 months.The import heating wire life-span is also less than 10 months.High voltage power distributing cabinet for electric substation's work, less than life-span of 1 year, some was short really in the element work of the inside, and in high-voltage board, whether the damage of heating plate is to have no idea to reflect on the temperature and humidity controller that is contained in outside, whether heating plate is unknown in work, also just had the hidden danger that dewfall occurs.
As can be seen here, a kind of good market prospects of heating plate that can automatic moistureproof clearing damp.
Summary of the invention
The technical problem that the present invention mainly solves is to provide the full-automatic moistureproof clearing damp heating plate of a kind of safety and energy-saving, can prevent high-voltage board dewfall, simplify greatly the formation of heating system, reduce costs, and it is fast to heat, can avoid the critical defect that temperature and humidity controller is controlled short and poor reliability of life-span of electric-heating-wire-heating plate.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of safety and energy-saving full-automatic moistureproof clearing damp heating plate, comprise base plate, heat sink plate and PTC ceramic wafer, described plate upper surface is provided with boss, described heat sink plate lower surface is provided with Baltimore groove, described heat sink plate is arranged on the top of described base plate by bolt, and it is inner that described boss is matched with described Baltimore groove, described heat sink plate has extension in described base plate both sides, and described PTC ceramic wafer is fixed on the boss top of described base plate by silicone band.
In a preferred embodiment of the present invention, the difference in height of described boss and described Baltimore groove is the thickness of described PTC ceramic wafer.
In a preferred embodiment of the present invention, described heating plate also comprises: power interface, described power interface is secured by bolts in the extension of described base plate.
In a preferred embodiment of the present invention, described PTC ceramic wafer and described power interface are communicated with by cable.
Beneficial effect of the present invention: the present invention adopts a kind of PTC ceramic wafer of novelty, its characteristic is before Curie temperature, resistance value is less and vary with temperature slower, after arriving Curie temperature, resistance value sharply increases, and can prevent high-voltage board dewfall, simplify greatly the formation of heating system, reduce costs, and it is fast to heat, can avoids the critical defect that temperature and humidity controller is controlled short and poor reliability of life-span of electric-heating-wire-heating plate.
Accompanying drawing explanation
Fig. 1 is the front view of the present invention in a preferred embodiment.
Fig. 2 is the vertical view of the present invention in a preferred embodiment.
In figure, each assembly and Reference numeral are respectively: 1, base plate, 2, heat sink plate, 3, PTC ceramic wafer, 4, power interface, 5, cable, 6, extension, 11, boss, 12, Baltimore groove.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Please refer to Fig. 1 includes at embodiments of the invention:
The full-automatic moistureproof clearing damp heating plate of a kind of safety and energy-saving, comprise base plate 1, heat sink plate 2 and PTC ceramic wafer 3, described base plate 1 upper surface is provided with boss 11, described heat sink plate 2 lower surfaces are provided with Baltimore groove 21, described heat sink plate 2 is arranged on the top of described base plate 1 by bolt, and described boss 11 is matched with described Baltimore groove 21 inside, described heat sink plate 2 has extension 6 in described base plate 1 both sides, and described PTC ceramic wafer 3 is fixed on boss 11 tops of described base plate 1 by silicone band.
Described heating plate also comprises: power interface 4, described power interface 4 is secured by bolts in the extension 6 of described base plate 1.
Described PTC ceramic wafer 3 and described power interface 4 are communicated with by cable.
The difference in height of described boss 11 and described Baltimore groove 21 is the thickness of described PTC ceramic wafer 3, can make PTC ceramic wafer make temperature conduct and to come sooner in heating.
Further illustrate, at power interface, 4 places connect with the mains, the PTC ceramic wafer 3 connecting by cable 5 starts heating, before its temperature reaches Curie temperature, resistance value is less and vary with temperature very slow, can depress work in very wide alterating and direct current, during startup, current ratio is larger, and temperature rises very soon; When temperature reaches Curie temperature, resistance just sharply increases, and electric current subtracts and at once, and temperature is maintained in stationary temperature, thereby realizes the effect of anti-condensation.
Be different from prior art, this exothermic material characteristic can realize the requirement of anti-condensation in high-voltage board: quick powerful the heating of energy when in-cabinet temperature is low; When in-cabinet temperature rises, can substantially stop heating, the variation of the temperature that automatically conforms, has avoided the critical defect that temperature and humidity controller is controlled short and poor reliability of life-span of electric-heating-wire-heating plate.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes specification of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
