Abstract
The utility model relates to a DC electric heater. A resistance wire immersed in insulation liquid is arranged in a sealed heat conduction casing, the resistance wire and a DC power supply are connected, DC is obtained by that isolated depressurization and rectifying voltage stabilization are carried out to commercial power of 220V voltage via a transformer, and accordingly, the utility model is totally isolated from the commercial power and the DC can be below the safety voltage of 36V. The utility model has the advantages that the electric heater and the commercial power are isolated, safety is good, empty burning can be carried out for a long time, power is small, power is saved, damage can not be generated to a human body, and the utility model can be made into a liquid heater, a gas heater, etc.
Description
The utility model relates to a kind of DC potential device that object is heated of can be used for.
Existing electric heater is to use the 220V civil power voltage of working basically, and power is big, electricity wasting is containing potential safety hazard in varying degrees, and electric heater all has certain requirement to power line, kilowatt-hour meter, hydraulic pressure, water quality etc., can not emptyly burn, can not make the back standard.Heat-storage electric heater volume is big, and is more powerful, installs inconvenient.Above-mentioned shortcoming limits the development of existing electric heater in various degree.
The purpose of this utility model just provides a kind of use low-work voltage, can burn by long-time sky, and power is little, power saving, and electric heater and 200V mains isolation, safety is given birth to, and can not produce the DC potential device of injury to human body.
Solution of the present utility model is such: be provided with the D.C. resistance silk in airtight container.Resistance wire is salable to have the resistance wire that is immersed in the iknsulating liquid in heat conduction shell in the sealing heat conduction shell, resistance wire is to join with DC power supply.Resistance wire also can adopt the mode in the housing that is positioned over the solid conductive heat material seal to make electric heater.And direct current can obtain by isolating transformer step-down, rectifying and voltage-stabilizing from civil power 220V voltage, thereby the utility model and civil power are isolated fully, and direct voltage department gets below the 36V safe voltage.
The utility model has the advantages that electric heater and mains isolation, safety is given birth to, and can burn by long-time sky, and power is little, and power saving can not produce injury to human body.
Accompanying drawing is embodiment of the present utility model.
Accompanying drawing 1 is first kind of example structure schematic diagram of the present utility model.
Accompanying drawing 2 is second kind of example structure schematic diagram of the present utility model.
The utility model is to be provided with D.C. resistance silk 3 in airtight container.
In the embodiment shown in Figure 1, described airtight container is a sealing heat conduction shell 5, has the resistance wire 3 that is immersed in the iknsulating liquid 4 in it, and resistance wire 3 is to join with DC power supply.Be covered with heat exchanger 1 at sealing heat conduction shell 5.There is cold mouthful 6 on the described heat exchanger 1 and heat mouth 2.Described heat exchanger 1 can be to feed gas, and to gas heated, this type of heater is a gas heater; Also mouth feeds liquid, and to liquid heat, this type of heater is a liquid heater.
If think directly air to be heated, also can cancel heat exchanger 1, directly 5 pairs of heat conduction shells with sealing need the article (or atmosphere) of heating to heat.
In the present embodiment, direct current is by transformer B step-down through the 220V civil power, after rectification, voltage stabilizing, obtain safe direct-current working volts, this voltage is added in the two ends of low-power resistance silk, there is electric current to flow through in the resistance wire 3 and produces high heat heating dielectric 4, dielectric 4 is passed to sealing heat conduction shell 5 with heat, and sealing heat conduction shell 5 outer objects are heated.
In the embodiment shown in Figure 2, described airtight container is a sealing heat conduction shell 7, in it is to adopt Heat Conduction Material with resistance wire 3 sealings, and resistance wire is to join with DC power supply, this kind structure, replaceable existing alternating current heat pipe.
Resistance wire 3 of the present utility model is to adopt the low-power resistance silk, can use organizing the resistance wire serial or parallel connection more.The voltage of DC power supply can be optionally selected arbitrarily, and in the present embodiment, the voltage of described DC power supply is below 36V.
