The electric radiator structure without pipeline and liquid can effectively use the natural convection principle of air to quickly improve the indoor temperature, pipeline and liquid are not needed, light pollution and sound pollution are avoided, the heat exchange rate is high, the energy consumption is low, drying is avoided, and the water heating effect is realized for the north.
Description
Technical field
The present invention relates to a kind of without pipeline no liquid formula electric heater structure, belong to heating equipment technical field.
Background technology
Northern area heat supply in winter is mainly based on heating installation, be generally central heating, required hot water amount is very large, burnt a large amount of coals, and the circuit of central heating is very long, thermal loss is also very serious, and the circuit that sometimes heats also has breakage, waste a large amount of water resources, do not meet the social theme of the energy-conserving and environment-protective advocated now.
Southern area majority adopts electric heating equipment, in these electric heating equipments, for the employing directed radiation formula heating system of similar Sunny, the warm of local can be realized, but after distance heating system certain distance, be difficult to experience warmness, more cannot reach the overall effect heated up.Be popular in the Table capable of heating of Guizhou province or heating tea table recent years, can warm foot, blocked shot together of also sitting around.But, the maximum defect of this heating system is, be difficult to promote room temperature, heating comfort level is lower, and the knee through ordinary person is baked to obtain pain, but back but still feels ice-cold, a large amount of heats is collected on body of heater itself, be easy to scald human body, heat exchanger effectiveness is low, and capacity usage ratio is not high.
In addition, though the liquid-filled warmer being similar to oily spit of fland has the overall effect heated up, heating comfort level is higher, but inside needs to fill conduction oil, and high to the sealing requirements of warmer, weight own is large, and user satisfaction is not high.Non-natural convection type is as air-conditioning and warm-air drier one class forced convection type heating system, and energy fast lifting room temperature, and generation dust, have noise.In addition, gas warm-air machine produces pernicious gas along with burning, causes air pollution.
Therefore, people's immediate concern have a can fast lifting bulk temperature, without light pollution with without sound pollution, rate of heat exchange is high, energy consumption is low electric heating equipment.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of without pipeline no liquid formula electric heater structure, without light pollution with without sound pollution, rate of heat exchange is high, energy consumption is low, can fast lifting entirety room temperature, to overcome the deficiencies in the prior art.
The object of the invention is to be achieved through the following technical solutions:
One, without pipeline no liquid formula electric heater structure, comprises electric heating body, heat radiation fin, described heat radiation fin is arranged on electric heating body both sides, described heat radiation fin is provided with heating power passage, and heat radiation fin arranged outside has baffle plate, forms air inlet between the lower end of baffle plate and heat radiation fin.
Preferably, the cross sectional shape of described heating power passage comprises U-shaped, triangle, wedge shape or trapezoidal.
Preferably, the tooth depth of the U-shaped cross sectional shape of described heating power passage is 2 times of space width.
Preferably, described electric heating body comprises the electric heating body without light pollution such as PTC ceramic heating bar or silicon wafer Electric radiant Heating Film.
Preferably, insulating trip is provided with between described electric heating body and heat radiation fin.
After adopting said structure, beneficial effect of the present invention:
1, the present invention can effectively utilize natural convection air principle and improves indoor temperature fast, i.e. electric heating body energising release heat, cold air in indirect heat radiation fin, flow out upward because air heats density diminishes along heating power passage, cold air is sucked by the air inlet of baffle plate lower end, so continuous circulation, forms convection current, improves indoor temperature fast.
2, heating power passage can increase the area of dissipation of heat radiation fin, adds the total amount of heated air contact area and heated air, is conducive to fast lifting temperature; Heating power channels designs is U-shaped odontoid, and structure is simple, is easy to manufacture; The tooth depth of U-shaped tooth is 2 times of space width, and the depth making heating power passage is comparatively large, and in conjunction with baffle plate to form a narrow and small heating power passage, unit heated gas flow is diminished, and air is faster by the speed heated.
3, because the existence of baffle plate, make to form a relative narrow space between radiating fin with baffle plate, small space makes hot-air specific discharge diminish, and air is accelerated by the speed heated.Radiating fin and baffle arrangement acting in conjunction, strengthen cross-ventilated speed, air flowed faster, thus improve the frequency of heat exchange.
4, the present invention is by adding hot air heating, without pipeline, inner without the need to filling heat conduction wet goods liquid, has both reduced the production cost of electric heater, and has made again electric heater easy to use, and avoided the trouble that may run in use, without light pollution with without sound pollution.
5, be provided with insulating trip between electric heating body and heat radiation fin, prevent electric leakage, safe and reliable.

Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, invention is described further:
A kind of without pipeline no liquid formula electric heater structure, adopt PTC ceramic heating bar or silicon wafer Electric radiant Heating Film etc. as electric heating body 1, heat radiation fin 3 is set in the both sides of electric heating body 1, between electric heating body 1 and heat radiation fin 2, be provided with insulating trip 2.Described heat radiation fin 3 is provided with heating power passage 5, and heating power passage is U-shaped odontoid, and the tooth depth of U-shaped tooth is 2 times of space width.In distance heat radiation, fin 3 outermost end 40-65mm place is provided with baffle plate 4, and the lower end of baffle plate 4 exceeds the lower end formation air inlet of heat radiation fin 3.
Operation principle of the present invention has used free convection principle, so-called free convection principle: refer to that inside air also exists temperature difference, and make the density of each several part air different, the atmospheric density that temperature is high is little, must rise; The atmospheric density that temperature is low is large, must decline, thus cause the flowing of inside air to be free convection.This effect not having external mechanical force, only by inside air temperature difference, and makes air flow thus the phenomenon of Heat produced, is called free convection heat transfer.
When electric heating body 1 is energized release heat, cold air in radiating fin 3 is heated indirectly, because hot-air density diminishes, flowed out upward by heating power passage 5, cold air fills up the space stayed because hot-air flows away simultaneously, be drawn into radiating fin 3 from the air inlet below baffle plate 4, in radiating fin 3, become hot-air by heating, continue to flow upward along heating power passage 5.Meanwhile, the cold air flowed out outside the hot-air of radiating fin 3 and equipment meets, and after turning cold, density increases, and progressively sinks, so continuous circulation, forms the free convection of air to improve indoor temperature.
