Abstract
The utility model discloses an electrical water heater heating unit which comprises a ceramic heating tube, a trepanning foam copper, an electrode and a heating tube connection kit, wherein the trepanning foam copper is connected in the ceramic heating tube in a brazing mode, a black heating film is coated on a surface of the ceramic heating tube, two ends of the ceramic heating tube are connected with the electrode, and the heating tube connection kit is connected with the ceramic heating tube. The electrical water heater heating unit enables surface temperature of the ceramic heating tube to be lowered due to efficient heat transfer of the trepanning foam copper, and overheating can be avoided; since a red copper of the trepanning foam copper has high resistance to corrosion, production of incrustation can be effectively reduced, and a certain role of killing virus and eliminating bacteria is played; since the ceramic heating tube instantly conducts heat and dissipates heat through the trepanning foam copper, thermal losses of the ceramic heating tube are reduced, and an energy-saving effect is achieved; since the electrode is connected outside of the ceramic heating tube, water flows in the ceramic heating tube, separation of water and electricity is achieved, and then safety performance is improved. The electrical water heater heating unit is applied to not only electrical water heaters but also liquid heating devices in the field of heat exchange such as water dispensers, humidifiers and foot baths.
Description
Technical field
The utility model relates to a kind of heater of electric heater, is specifically related to a kind of electric heater heater.
Background technology
At present domestic, electric water heater is commonly used mainly contains storage-type and Instant heating type.Usually need before storage-type electric water heater uses earlier the water in the storage tank is heated, have that volume takes up room greatly, firing rate waits shortcoming slowly.Than storage-type electric water heater; The instant electric water heater has the advantage of Fast Heating, plug and play, advantages of small volume; But need usually to adopt high-power heating tube, this heating tube surface is smooth light face structure, does not also have micropore in the pipe; Ubiquity power consumption is big, the efficiency of heating surface (being electricity-thermal conversion efficiency) is low, it is inhomogeneous to conduct heat, heat-generating pipe short defective in service life, and is also higher to the requirement of ammeter, electric wire.In addition, be usually used in the immerging metal tube heater in the electric heater because long period of soaking is worked the easy one deck incrustation scale that forms in surface in water.Receive the influence of incrustation scale, the heat that the heat-generating pipe energising produces can not in time be delivered in the water, causes the heat-generating pipe long-term work in the condition of high temperature, not only causes heat transference efficiency low, and power consumption is big, also is easy to generate dangerous accidents such as electric leakage, explosion.
Summary of the invention
The purpose of the utility model provides a kind of electric heater heater, and it can realize Fast Heating, energy saving, and also safe and reliable.
The utility model is realized through following technical scheme: it comprises that ceramic heating pipe, open celled foam copper, electrode and heat-generating pipe connect external member; It is characterized in that open celled foam copper is connected in the ceramic heating pipe through soldering; Scribble the black heating film at the ceramic heating tube-surface; The outer two ends of ceramic heating pipe connection electrode, electrode is connected with the 220V50HZ power supply, and heat-generating pipe connects external member and connects the ceramic heating pipe.When water passes through in the ceramic heating pipe; Open celled foam copper places mobile water; Owing to specific area high in the open celled foam steel structure and complicated Three-dimensional Flow; 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 water fully absorb the heat of ceramic heating pipe 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.
Described heater is connected through soldering with open celled foam copper by the ceramic heating pipe.
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 heater, thereby realize Fast Heating; (2) because the effective heat transfer of foam copper can make ceramic heating tube-surface temperature reduce, can avoid occurring burn-off phenomenon, thereby prolong heat-generating pipe service 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; (4) because ceramic heating element conducts heat rapidly, dispels the heat through foam copper, make its thermal losses obtain reducing, have energy-conservation effect; (5) because electrode is connected the ceramic heating tube outside, and water is in the ceramic heating pipe, to flow through, and has realized electricity separation, thereby has improved security performance.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Wherein: 1, ceramic heating pipe; 2, open celled foam copper; 3, electrode; 4, heat-generating pipe connects external member.
The specific embodiment
Shown in accompanying drawing 1; The utility model comprises that ceramic heating pipe 1, open celled foam copper 2, electrode 3 and heat-generating pipe connect external member 4; It is characterized in that: open celled foam copper 2 is connected in the ceramic heating pipe 1 through soldering, scribbles the black heating film on ceramic heating pipe 1 surface, the outer two ends of ceramic heating pipe connection electrode 3; Electrode is connected with the 220V50HZ power supply, and heat-generating pipe connects external member 4 and connects the ceramic heating pipe.When water passes through in the ceramic heating pipe; Open celled foam copper places mobile water; Owing to specific area high in the open celled foam steel structure and complicated Three-dimensional Flow; 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 water fully absorb the heat of ceramic heating pipe and carries out exchange heat rapidly, thereby with the water Fast Heating.
The utility model can avoid occurring burn-off phenomenon because the 2 effective heat transfers of open celled foam copper can make ceramic heating pipe 1 surface temperature reduce; Because the red copper of open celled foam copper 2 has very high resistance to corrosion, can effectively reduce the generation of incrustation scale, has certain virus killing bacterium effect that disappears; Because ceramic heating pipe 1 conducts heat rapidly and heat radiation through open celled foam copper 2, make its thermal losses obtain reducing, have energy-conservation effect; Because electrode 3 is connected ceramic heating pipe 1 outside, and water is in ceramic heating pipe 1, to flow through, and has realized electricity separation, thereby has improved security performance.The present invention not only is adapted to electric heater, and is suitable equally for the liquid heating in heat exchange fields such as water dispenser, humidifier, Pediluvium apparatus.
