Description

Electric heater with longitudinal finned heat pipe
Longitudinal fin heat-pipe electric heater art
The present invention relates to a kind of indoor electric heater, formed by PTC thermal sensitive ceramicses heating element heater with longitudinal fin gravity assisted heat pipe and shell combination.Background technology
Current heating of house is using concentration heating and scattered individually two major classes of heating.With social development and the raising of living standards of the people, disperseing independent heating mode has great development, and the need for southern area winter, individually heating turned into popular, the development individually warmed oneself also is greatly facilitated in Rural Urbanization Construction.Again due to environmental protection the problem of, electricity heating has become the necessity of popular life.Electric heater in the market mainly has electric heating installation using oil as medium, Resistant heating etc. several, generally existing electric conversion efficiency is not high, heat transfer rate is slow, need the weak points such as corresponding temperature control equipment so that electric heater exist inefficient, cost it is higher, it is fragile the shortcomings of.The present invention intends using PTC thermal sensitive ceramicses heating element heater with longitudinal fin gravity assisted heat pipe and shell combination into a kind of brand-new electric heater, to overcome the above-mentioned deficiency of conventional electric heater.The content of the invention
The technical solution used in the present invention is：Electric heater is made up of PTC thermal sensitive ceramicses heating element heater, longitudinal fin gravity assisted heat pipe, bearing and the major part of housing four.Electrical insulating film is surrounded by outside PTC thermal sensitive ceramics heating element heaters, is arranged between intubation plate and bearing；The hot junction of some longitudinal fin gravity assisted heat pipes is inserted in the corresponding hole of intubation plate, is pressurizeed by compression spring and is caused the planar base surface in longitudinal fin gravity assisted heat pipe hot junction to have good contact with electrical insulating film.In order to improve the performance of longitudinal fin gravity assisted heat pipe, the vertical longitudinal fin of integration, the heat-transfer working medium that longitudinal fin gravity assisted heat pipe is vacuumized and injected are set in the longitudinal fin gravity assisted heat pipe tube surfaces of aluminum.The housing of cylinder is set outside every longitudinal fin gravity assisted heat pipe, is formed between housing cavity and longitudinal fin gravity assisted heat pipe and detachable connection is formed between air duct, housing.
The operation principle of this electric heater is：First, make PTC thermal sensitive ceramics heating element heater heating powers, heat is transmitted to the hot junction of heat conducting element longitudinal fin gravity assisted heat pipe by electrical insulating film, the heat in hot junction makes the working medium in longitudinal fin gravity assisted heat pipe heated and vaporized, because longitudinal fin gravity assisted heat pipe has been vacuumized, liquid in pipe can just be vaporized at a lower temperature, steam rises to longitudinal fin gravity assisted heat pipe upper end in the middle of longitudinal fin gravity assisted heat pipe, the block cooling of the longitudinal fin gravity assisted heat pipe of lower temperature is run into upper end and heat of vaporization is discharged, become liquid again and rely on gravity reflux along longitudinal fin gravity assisted heat pipe inner surface, form working cycles.Liquid becomes steam and become again in the On The Cycle Working Process of liquid in longitudinal fin gravity assisted heat pipe, substantial amounts of heat is transmitted to the air around fin by fin, air is heated below housing to enter the air duct that housing and longitudinal fin gravity assisted heat pipe are collectively forming, air rises along the passage between longitudinal fin, progressively heat up, exhausting effect is formed in the space of similar chimney, until the top in hot junction accelerates effusion, in the air got in, room is set to warm.
PTC thermal sensitive ceramics pieces are the heating element heaters of electric heater, when PTC thermal sensitive ceramics piece temperature reaches the i.e. curie point of setting value, the resistance of PTC thermal sensitive ceramics pieces becomes very big, and electric current becomes very little, PTC thermal sensitive ceramics pieces do not heat up, and electric heater is at holding state.When PTC thermal sensitive ceramics piece temperature drops to below curie point, electric heater is started working again.The temperature of PTC thermal sensitive ceramics pieces is lower, and input current is bigger, and PTC thermal sensitive ceramics piece temperature is stepped up, and resistance progressively becomes big, and input current progressively diminishes, the need for both meeting heating of house, can play high temperature self-shield again.
It is of the invention substantially the characteristics of and have the beneficial effect that：（1) electric heater is divided into PTC thermal sensitive ceramicses heating element heater, longitudinal fin gravity assisted heat pipe, housing and the big part of bearing four to constitute, the clear function of each part, meet function and the one-to-one design method principle of function element, structure is concise, irredundant element, cost is low, easy to maintenance；（2) PTC thermal sensitive ceramicses heating unit Part can voluntarily control the maximum temperature of electric heater, play energy-conservation and safety effect；（3) heat transfer of longitudinal fin gravity assisted heat pipe is fast, and housing is combined into vertical enclosed channel with longitudinal fin gravity assisted heat pipe again, plays exhausting effect, and air can be made to accelerate circulation inside and outside heater；（4) the preferable combination of PTC thermal sensitive ceramicses heating element heater and longitudinal fin gravity assisted heat pipe, efficiently utilizes electric energy；(5) one group is constituted by a piece of PTC thermal sensitive ceramicses heating element heater and a longitudinal fin gravity assisted heat pipe, some groups of parallel combinations are into electric heater.Any group of failure does not influence other groups of work.Brief description of the drawings
It in the general assembly drawing of longitudinal fin heat-pipe electric heater, figure 1 is housing that accompanying drawing, which is,；2 be bearing, is intubated plate, the circlips of 2- 3 and 2-4 compression springs by 2-1 supports, 2-2 and is combined；3 be PTC thermal sensitive ceramics heating element heaters；4 be longitudinal fin gravity assisted heat pipe；5 be power outlet；6 be spike.Embodiment
It is intubated in the middle of plate and bearing and PTC thermal sensitive ceramicses heating element heater and electrical insulating film is set, is easy to dismounting；Meanwhile, there should be larger space between bearing and housing, in favor of the entrance of air.The another spike for being equipped with electric heater, can make heater stand upright on ground on bearing；Compression spring is set on intubation plate, longitudinal fin gravity assisted heat pipe termination is set to be pressed on PTC thermal sensitive ceramics heater element surfaces with constant force, the pore of intubation plate should have preferable fit precision with longitudinal fin gravity assisted heat pipe hot junction, it is ensured that can be moved when longitudinal fin gravity assisted heat pipe expands with heat and contract with cold in hole.
Longitudinal fin gravity assisted heat pipe is formed by aluminum profile extrusion, and body is integral with fin, to ensure high heat conduction.
The size of housing is it is ensured that have certain space, to form the circulation passage of air, generation exhausting effect between housing and longitudinal fin gravity assisted heat pipe；Outside is provided with some dark formula hooks to housing on one side, breaks hook into two with one's hands, electric heater can be hung on wall.
The technology of the present invention can also be used in the combination with other thermals source, such as common resistance heating wire, but must increase the control to resistance heating temperature.
