Abstract
The utility model discloses a copper foam heating unit, which comprises an opening copper foam, a flanked red copper tube, magnesium oxide powder and an electrode, wherein the opening copper foam is connected with upper and lower sides of the flanked copper tube through braze welding; the magnesium oxide powder is filled in the red copper tube; and the electrode passes through the magnesium oxide powder. According to the copper foam heating unit, the opening copper foam with a large specific surface area has a superior heat transfer and heat dissipation performance, so that water can be heated quickly due to full heat transfer. As a surface temperature of the flanked red copper tube can be reduced due to effective heat transfer of the opening copper foam, unsafe phenomena such as overburning, electric leakage, bursting and the like are prevented. A red copper of the opening copper foam has high corrosion resistance, thus scale deposit is effectively reduced and a certain antiseptic and antibacterial effect is provided.
Description
Technical field
The utility model relates to a kind of heat exchange heater, relates in particular to a kind of foam copper heater.
Background technology
The electric water-heating apparatus that uses at present; Adopt the mode of resistance wire heating mostly like electric heater, electric kettle, coffee machine, boiler, water dispenser, soy bean milk making machine and culinary firing equipment, promptly through vertically spiral resistance wire in the metal tube under "on" position, produces heat and to the heat-generating pipe be the center transmit heat all around.In the mode of this resistance wire heating; The heating tube surface is smooth light face structure; And the metal catheter long period of soaking of heat-generating pipe heats in water, because mostly the water of heating is undressed hard water, is easy to make the metal catheter shell of heat-generating pipe to produce incrustation scale and corrosion.Receive the influence of incrustation scale, the heat that the heat-generating pipe energising produces can not in time be delivered in the water, not only reduces heat conduction efficiency, and power consumption is big; And cause the heat-generating pipe long-term work in the condition of high temperature, and influence heat-generating pipe useful life, more serious situation is to produce dangerous accidents such as electric leakage, explosion.
Summary of the invention
The purpose of the utility model provides a kind of foam copper heater, and it can realize Fast Heating, and safe and reliable.
The utility model is realized through following technical scheme: it comprises open celled foam copper, band flank copper tube, magnesia powder and electrode; It is characterized in that open celled foam copper is connected band flank copper tube both sides up and down through soldering; Fill magnesia powder in the band flank copper tube; Be connected with electrode in the middle of the magnesia powder, electrode is connected with the 220V50HZ power supply.When the foam copper heater was positioned in the water and switches on, the heat that electrode produces magnesia powder good through heat conductivility and that have insulation property passed to band flank copper tube.Because open celled foam copper has big specific area; Heat transfer, heat dispersion on the unit volume are superior; Water has complicated Three-dimensional Flow in open celled foam copper; Heat can be to distribute the water of forced convertion form through the hole, i.e. the increase of water and open celled foam copper contact area makes the heat of the abundant absorption band flank of water copper tube and carries out exchange heat rapidly, thereby with the water Fast Heating.
Described open celled foam copper is made the open celled foam attitude by the red copper material and is formed.
The utility model compared with prior art has following advantage: (1) is because copper is high thermal conductivity (being only second to noble metal silver) material; It is made the open celled foam attitude; Can increase the specific area of material greatly, thereby significantly improve the heat transfer on the red copper unit volume, the effect of heat radiation, and then improve the efficiency of heating surface of heating element; Heat can fully be transmitted, and water is heated rapidly; (2) because the effective heat transfer of open celled foam copper can make band flank copper tube surface temperature reduce, avoid occurring dangerous phenomenons such as burning, electric leakage, explosion, thereby prolong heat-generating pipe useful life; (3) because the red copper of foam copper has very high resistance to corrosion, can effectively reduce the generation of incrustation scale, have certain virus killing bacterium effect that disappears.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Wherein: 1, open celled foam copper; 2, band flank copper tube; 3, magnesia powder; 4, electrode.
Embodiment
Shown in accompanying drawing 1; The utility model comprises open celled foam copper 1, band flank copper tube 2, magnesia powder 3 and electrode 4; Open celled foam copper 1 is connected band flank copper tube through soldering, and about in the of 2 both sides; Fill magnesia powder 3 in the band flank copper tube, be connected with electrode 4 in the middle of the magnesia powder, electrode is connected with the 220V50HZ power supply.When the foam copper heater was positioned in the water and switches on, the heat that electrode produces magnesia powder good through heat conductivility and that have insulation property passed to band flank copper tube.Because open celled foam copper has big specific area; Heat transfer, heat dispersion on the unit volume are superior; Water has complicated Three-dimensional Flow in open celled foam copper; Heat can be to distribute the water of forced convertion form through the hole, i.e. the increase of water and open celled foam copper contact area makes the heat of the abundant absorption band flank of water copper tube and carries out exchange heat rapidly, thereby with the water Fast Heating.
The utility model can avoid occurring dangerous phenomenons such as burning, electric leakage, explosion because the 1 effective heat transfer of open celled foam copper can make band flank copper tube 2 surface temperatures reduce; Because the red copper of foam copper has very high resistance to corrosion, can effectively reduce the generation of incrustation scale, has certain virus killing bacterium effect that disappears.The utility model is applicable to electric water-heating apparatus such as electric heater, electric kettle, coffee machine, boiler, water dispenser, soy bean milk making machine.
Claims (2)
