Abstract
An electrothermal film as the heating element of water heater is disclosed. Said electrothermal film is plated on the external surface of a heating pipe made of insulating material. A spiral core bar is installed in the heating pipe. When water flow through the heating pipe along a spiral route, it is heated by the electrothermal film in heat exchange mode. Its advantages are full heat exchange, and high heat efficiency (more than 98%).
Description
The present invention relates to water heater, particularly relate to the hot assembly in the electric heating film water heater.
Along with the raising of people's living standard, the use of water heater is more and more general, and pot-type boiler mainly contains combustion type, electric heating tubular type, several big classes of eddy current type.Gas water heater reduces because of its safety issue user, and electric heating tubular type water heater is generally water storage box type, needs preheating, energy consumption for keeping temperature, causes shortcomings such as waste.Though the instant electric water heater is arranged in the market, power perhaps reaches 6000W at 3000-5500W, so be not suitable for using in the general family.Characteristics such as thereby existing developed electric heating film water heater again, this heating element is glass tube or the earthenware that is coated with transparent electric heating film, is heated when time in the water flowing pipe, and it is little, easy for installation to have a volume, safe in utilization.But existing electric heating film water heater is because heating tube only is a straight pipe, and water is mobile too fast in pipe, be again along tube wall almost always along tube wall, can not obtain sufficient heat exchange, the intensification amplitude is little, especially winter, do not reach and use the water temperature requirement, therefore, be difficult to promote.
The objective of the invention is to overcome the structure defective of existing electric heating film water heater heating tube, provide a kind of cold water to flow through and constantly change flow regime in the heating tube, tube wall is carried out sufficient heat exchange, improve the hot assembly of the electric heating film water heater of the heat efficiency.
The technical scheme of heating module for water heater with electrothermal film to heat directly of the present invention is: by the heating tube that insulating material is made, heating tube is coated with transparent electric heating film outward, and helix core rod is installed in the Electric radiant Heating Film joining power, its heating tube.
Heating module for water heater with electrothermal film to heat directly of the present invention, the external diameter φ of its helix core rod
1Less than heating tube internal diameter φ
2
Heating module for water heater with electrothermal film to heat directly of the present invention, the spacing of the external diameter of its helix core rod and heating tube inwall is the 0.3-2 millimeter.
Heating module for water heater with electrothermal film to heat directly of the present invention, its heating tube are one group of two heating tubes arranged side by side.
Heating module for water heater with electrothermal film to heat directly of the present invention, its described heating tube are microcrystal glass tube or quartz glass tube or earthenware.
Heating module for water heater with electrothermal film to heat directly of the present invention, its heating tube two is fixedly connected by end cap, is shaped on the discharge orifice in the end cap, and the discharge orifice connects water inlet pipe and hot water outlet pipe.
The invention discloses a kind of hot assembly of Electric radiant Heating Film immediately heating water heater, helix core rod has been installed in heating tube, plug and heating tube inwall have little clearance, in the time of in hydraulic pressure is gone into heating tube, advance along helix and gap, the one, constantly change flow regime, avoid a direction to flow; The 2nd, water flowing time in heating tube prolongs, and runner can increase (promptly 20 centimetres heating pipe is equivalent to 8 meters long) about 40 times, increases caloric receptivity; The 3rd, water is many with heating tube wall touch opportunity, and heat exchange is abundant, makes the heat efficiency reach 98%.
Fig. 1 is a heating module for water heater with electrothermal film to heat directly assembling schematic diagram of the present invention;
Fig. 2 is that electric heating of the present invention is touched immediately heating water heater heating tube schematic diagram;
Fig. 3 is an Electric radiant Heating Film immediately heating water heater helix core rod schematic diagram of the present invention.
Below in conjunction with Fig. 1-Fig. 3 embodiments of the invention are done detailed explanation.
The present invention relates to heating module for water heater with electrothermal film to heat directly, the material of insulation heating tube 5,6 can adopt microcrystal glass tube or quartz glass tube or earthenware, plate transparent Electric radiant Heating Film in the outside of heating tube, Electric radiant Heating Film connects the power supply heating power, becomes heating resistor.Heating tube 5,6 can be used one or more, but be generally one group two mutually arranged side by side, as shown in Figure 1, maximum characteristics are that helix core rod 3,4 is installed in heating tube 5,6, the best is the external diameter φ of helix core rod 3,4
1Internal diameter φ less than heating tube 5,6
2, make it stay little clearance between the two, be generally the 0.3-2 millimeter, perhaps greater than 2 millimeters, both along the hand of spiral, constantly impact tube wall again when making in the water flowing pipe, advance along wall, carry out sufficient heat exchange.At two of heating tube end cap 2,9 is installed and is fixed, be shaped on discharge orifice 1,8,10 in the end cap, the discharge orifice is communicated with water inlet pipe 11 and hot water outlet pipe 7.After in heating tube 5,6 helix core rod 3,4 being installed, than uneasy plug, the heating water temperature generally increases 3-5 ℃, and the heat efficiency can reach more than 98%.
