Abstract
The utility model discloses a hollow flue teakettle which comprises a kettle body, a hollow flue, a kettle handle, a kettle mouth and a kettle cover. The hollow flue comprises a main flue and two branch flues, and additionally, the surface of the hollow flue conducts dull polishing processing. When the hollow flue teakettle heats up water, due to the effect of the hollow flue, flame can not again flow past along the outer side of the kettle body and is transferred to flow past the hollow flue, the flame firstly passes through the main flue and then passes through the two branch flues, so that energy in the flame is all used for heating for water. Temperature of the outer wall of the kettle body does not exceed 100 DEG C, the temperature of the flame is about 800 DEG C, by a thermal radiation law that Phi =epsilon A sigma T4, a large amount of heat loss is reduced compared with original flame which surrounds the outer side of the kettle body, and heat transferring efficiency is improved. After the surface of the hollow flue conducts dull polishing processing, the blackness epsilon is improved. By the thermal radiation law that Phi =epsilon A sigma T4, under the same heating condition, after the blackness epsilon is improved, the heat transferring amount Phi is increased, and therefore, heat transferring efficiency of the flame and cold water in the kettle body is improved.
Description
Technical field
The utility model relates to the daily living article technical field, is specifically related to a kind of hollow flue kettle teapot.
Background technology
The use of kettle teapot is comparatively frequent in the daily life, and common kettle teapot comprises: kettle body, pot lid, kettle handle and Hu Zui.The inventor finds that kettle teapot is when heating up water, flame encompasses is at the bottom of kettle and outside the kettle body, flame temperature is about 800 ℃, thermal radiation law Φ=ε A σ T4 knows, the flame in the kettle body outside is except the feedwater heating, and also environment dispels the heat with the form of radiation and convection current towards periphery, because the temperature of environment is also lower than the temperature of kettle, cause the most of heat loss of flame to fall, the heating of not feeding water of this part energy; In addition, bottom surface blackness ε is less at the bottom of the smooth kettle, and heat exchange efficiency is lower like this, and the cold water heat exchange that flame is inabundant and kettle is interior has caused certain energy waste.Therefore, be necessary kettle teapot of the prior art is improved, promote the heat up water heat exchanger effectiveness of process of kettle teapot.
The utility model content
The purpose of this utility model is to provide a kind of hollow flue kettle teapot, this kettle teapot novel structure, and the heat absorption rate is high.
The utility model to achieve these goals, the technical solution of employing is: a kind of hollow flue kettle teapot comprises the kettle body, the hollow flue, kettle handle, Hu Zui and pot lid, the hollow flue comprises a flue collector and two branch flues, and the frosted processing is done on hollow flue surface in addition.
The beneficial effects of the utility model: this kind kettle teapot is when heating up water, because the effect of hollow flue, so that flame no longer flows through along the kettle body outside, change the hollow flue of flowing through into, pass through first flue collector, again through two branch flues, energy in the flame all is used for feeding water and heats like this, kettle body outside wall temperature is no more than 100 ℃, and about 800 ℃ of flame temperature is by thermal radiation law Φ=ε A σ T
4Know, in the kettle body when outside, reduced a large amount of heat loss than original flame encompasses, improved heat exchange efficiency; Process through frosted on hollow flue surface, so that blackness ε raising, by thermal radiation law Φ=ε A σ T
4Know that after blackness ε under the identical heating state improved, heat exchange amount Φ increased, thereby improved the heat exchanger effectiveness of cold water in flame and the kettle.
Description of drawings
Fig. 1 is the structure diagram of hollow flue kettle teapot.
Fig. 2 is the front view of hollow flue kettle teapot.
1 kettle handle among the figure, 2 pot lids, 3 branch flues, 4 kettle bodies, 5 flue collectors, 6 Hu Zui, 7 flames
The specific embodiment
Below in conjunction with Fig. 1, Fig. 2 the utility model is elaborated:
Hollow flue kettle teapot comprises (1) kettle handle, (2) pot lid, and the hollow flue comprises (5) flue collector and (3) branch flue, (4) kettle body, (6) Hu Zui.Described hollow flue surface is frosting.
This kind kettle teapot is when heating up water, because the effect of hollow flue, so that flame (7) no longer flows through along kettle body (4) outside, change the hollow flue of flowing through into, pass through first flue collector (5), again through two branch flues (3), enter at last in the air, the energy in the flame (7) all is used for feeding water and heats like this, and kettle body (4) outside wall temperature is no more than 100 ℃, about 800 ℃ of flame temperature is by thermal radiation law Φ=ε A σ T
4Know, when surrounding kettle body (4) outside than original flame (7), reduced a large amount of heat loss, improved heat exchange efficiency; Process through frosted on hollow flue surface, so that blackness ε raising, by thermal radiation law Φ=ε A σ T
4Know that after blackness ε under the identical heating state improved, heat exchange amount Φ increased, thereby improved the heat exchanger effectiveness of cold water in flame and the kettle.
Claims (2)
1. hollow flue kettle teapot is characterized in that: comprise the kettle body, and the hollow flue, kettle handle, Hu Zui and pot lid, hollow flue comprise a flue collector and two branch flues.
