Description

Horizontal cross convection type is cold, warm up dual-purpose electric heating installation using oil as medium
Technical field
The present invention relates to a kind of electric heating installation using oil as medium, especially horizontal cross convection type are cold, warm up dual-purpose electric heating installation using oil as medium.
Background technology
Electric heating installation using oil as medium, also referred to as oil-filled electric heating device, its advantage is that heating is uniform, odorlessness, clean environmental protection, comfortable Degree is high, is controlled by bimetallic strip temperature switch during work, is constantly in switching, switching ... service intermittent mode, has There is " pulsewidth modulation " function, its actual little power consumption is in rated operating power, thus power savings are than more significant.There is no " little too The drawbacks of sun ", electrothermal tube, plane formula warmer temperature rise, drop.Oil Heater heats whole room, the same just like air-conditioning Effect, but the price of oil Heater is only 5-10/mono- of air-conditioning.Because the thermal inertia of oil is very big, the oil of oil Heater has heat accumulation work( Can, even if power-off, the oil temperature in oil Heater still can maintain 10-20 slowly to lower the temperature for many minutes, and this is that oil Heater takes different from other The great advantage of warmer.In normal heating work, once reducing, electric automatic control is switched and be powered immediately heating oil temperature, is protected Hold temperature constant constant.The disadvantage of oil Heater is that when just starting working, programming rate is very slow, many points of generally up to 10-20 Clock, power consumption is very big in initial temperature-rise period, until reaching operating temperature ratings after just enter " pulsewidth modulation " control stage. If the electrified regulation time of starting shooting can be accelerated, a large amount of power consumptions started shooting in the heating-up time are saved, then the comfortable effect one of oil Heater Point is no less than air-conditioning, also feels vexed, atmosphere draught-free problem without air-conditioning, more different from other warmers " once opening heat, one Close just cold " common fault.
Currently on the market during all electric heating oil Heater heating works, its hot-air is all that from bottom to top convection current is first reached Roof ceiling position, heats house top, and then hot-air is progressively from top to bottom transmitted to again middle part, the bottom in room, Only when on house, middle segment space be filled with after hot-air the body that can just be delivered to people, make one the temperature for experiencing heat energy It is warm.Obviously, such a very long Thermal Cycling, has wasted substantial amounts of electric energy and heat time.Secondly, it is currently all The fin of oil Heater be all a piece of, piece longitudinal arrangement, make thermal current form a passage upwards, more enhance hot-air Convection current upwards is rather than directly to the passage of human body radiation.
If it is horizontal cross convection type to change hot-air longitudinal direction convection type, make hot-air directly to human body even room Between bottom convection current, existing indirect heat transmission way will be changed for direct heat exchange pattern, allow the people in room to experience in advance The effect of thermal energy radiation, changes the hot-air circulating path of oil Heater heating, makes hot-air lateral radiation, i.e., first human body, first house Lower space, in rear house, the hot-air circulating path of upper space.
Northern China also using the considerable vapours of quantity, hot water pipeline formula warmer, is also still dissipated using longitudinal direction The heating blade of backing, all has that the heat time is long, the big problem of thermal waste.If by all of which transformation be open into, water The duct type warmer of flat heat exchange pattern, its heating effect, energy-saving effect will be very considerable!
Therefore, if the relatively low advantage of constant temperature when common oil Heater works at ordinary times, quiet, power consumption can be retained, a kind of start of design The method that initial stage of operation is rapidly heated, so that it may so that existing oil Heater becomes the more satisfied section of " perfection ", user Energy, environmental protection, the household appliances of novel practical.
