Abstract
The present invention relates to the field of electrical appliance manufacture and is one electrical heater with new structure and of new material. The electric heater includes electric heating pipes and finned pipes fixed into integral structure, and the finned pipes are produced through rolling aluminium pipe and the electric heating pipes are made of aluminium or copper. The present invention is used as heating element for air convection electric-heater, electrical heating curtain and industrial heater.
Description
Technical field: the present invention relates to the electric finned-pipe heater that a kind of new construction that cross-ventilation formula electric heater uses and new material are made, belong to electrical equipment manufacturing technology field.
Background technology: the present electric heater of manufacturing, mostly be stainless steel tube formula structure greatly, be not suitable for cross-ventilation formula electric heater.
Summary of the invention: the object of the present invention is to provide a kind of novel electric heater, the heating and the radiator that are used for cross-ventilation formula electric heater, its objective is such realization: electric finned-pipe heater, its composition comprises electric heating tube 1, finned tube 2, finned tube 2 is by whole rolling the forming of metal aluminum pipe, described electric heating tube 1 is to be made by metallic aluminium, finned tube 2 becomes overall structure with electric heating tube 1 Joint, the invention has the advantages that: because electric heating tube 1 and radiating fin pipe 2 are overall structures, the conduction of heat, radiation and convection current are fully reflected and utilize, the thermal efficiency nearly 100%.It is by whole rolling the forming of aluminum pipe that metallic aluminium rolls the chip finned tube, has contactless thermal resistance, heat-resisting shake and mechanical shock, and hot expansibility is good, and the conduct radiation area is big, helps characteristics such as cross-ventilation.It is that tight cover of aluminum pipe or casting are produced finned tube through roughing, finish rolling on the copper parent tube that copper pipe aluminium rolls the fin multiple tube, has the good heat transfer performance, thermal contact resistance is stable, corrosion resistance is strong and characteristics such as intensity height.The radiating effect of above-mentioned two kinds of finned tubes obviously is better than sheet string type and tension wrapped fin tube.The characteristics of electric finned-pipe heater are that quick heating, thermal efficiency height, safe and reliable, quiet operation, volume in light weight are little, can be used for the heater element of cross-ventilation formula electric heater, electric heating curtain and industrial heater etc.
Description of drawings: Fig. 1 is a structural representation of the present invention.
The specific embodiment one: the utility model is used for cross-ventilation formula electric heater.Electric finned-pipe heater, be to roll finned tube or copper pipe aluminium rolls the manufacturing of fin multiple tube with metallic aluminium, its composition comprises electric heating tube 1, finned tube 2, finned tube 2 is by whole rolling the forming of metal aluminum pipe, described electric heating tube 1 is to be made by metallic aluminium, finned tube 2 is for rolling the chip finned tube, finned tube 2 becomes overall structure with electric heating tube 1 Joint, it is to be formed by the whole system of aluminum pipe that metallic aluminium rolls formula finned tube 2, after binding post 4 energisings of finned tube 2 electric heaters, the heat that thermal resistance wire 3 sends directly conducts by electric heating tube 1 gives finned tube 2, air is heated the back and rises, form a negative pressure in the finned tubular radiator bottom this moment, and its cold air is constantly sucked the finned tube heat exchange by negative pressure, thereby in the indoor heating system that forms a natural convection air circulation.
The specific embodiment two: what present embodiment and the specific embodiment one were different is, finned tube 2 is to be made by metallic aluminium, electric heating tube 1 is to be made by metallic copper, and it is that tight cover of aluminum pipe or casting are produced finned tube through roughing, finish rolling on parent tube that copper pipe aluminium rolls the fin multiple tube.
