Abstract
The utility model provides a cool press sleeve fin radiator pipe type electric heater for railway train air conditioners and civil air conditioners. The electric heater is arranged at the exterior of an electric heating pipe. Radiator fins are uniformly and horizontally distributed through the heater from top down. The radiator fins have punches. Upper sides of the punch circumferences have fins of lotus shape; the fins firmly hold the electric heating pipe. The heat efficiency of the utility model is improved by 25% to 30%; the surface temperature of the electric heating pipe can be lowered by approximately 20%; in addition, the size is reduced to half that of a prior winding pipe type electric heater. Therefore, the utility model can substitute imported electric heating elements.
Description
Technical field
The utility model is the nest plate heat radiation tube electric heater of colding pressing that is applied in railroad train air-conditioner and the civilian air-conditioner.
Background technology
At present, the parts that the heating of railroad train air-conditioner is mainly used are for twining tube electric heater, this electric heater appearance and size is big, the easy superelevation of surface temperature, electrothermal tube surface temperature ubiquity overheating problem, brought hidden danger for train and passenger, be in design and the manufacturing and problem to be solved always.
Summary of the invention
Technical problem to be solved in the utility model is how to dwindle the volume of tube electric heater, how to reduce the temperature on electrothermal tube surface, gets so that the heat energy of electrothermal tube is fully utilized.
The technical solution of the utility model is such: from top to bottom run through in the outside of electrothermal tube and the uniform fin of level.
After adopting above technical scheme, its effect is conspicuous:
1, under constant power, condition with environment, the thermal efficiency can improve 2.5%～30%.
2, make the electrothermal tube surface temperature descend about 20%.
3, appearance and size has been dwindled half than existing wound form electric heater.
Description of drawings
Fig. 1 is a structure front view of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Among the figure: 1, electrothermal tube 2, fin 3, lotus shape fin
The specific embodiment
With reference to Fig. 1, Fig. 2, earlier fin (2) is used the mould blanking, again fin is set electrothermal tube run through central point after, be placed on another mould two central points are carried out the bifurcated otch, then fin is placed on the other mould and aims at bifurcated otch center and carry out the punching moulding, at this moment, just around the fin punching mouth upside gone out lotus shape fin (3).At last the fin that has fin (2) after the moulding is adopted the mode of colding pressing, and with the blocks of ground of specific purpose tool, overlap and be pressed onto on " U " shape electrothermal tube (1) tightly.Each fin is the uniform shape of level, the lotus shape fin (3) that the punching upside the forms electrothermal tube (1) of filling the span of a man's arms tightly, and be the tight fit shape.The utility model is when work, the thermal energy conduction of electrothermal tube (1) is arrived on the fin (2), then by fin (2) heat is distributed in the space towards periphery, at same environment, with under the constant power, the thermal efficiency of the present utility model can improve 25～30%, the electrothermal tube surface temperature can descend about 20%, and volume has also dwindled half, the electrical heating elements of alternative import than the existing tube electric heater that twines.
Claims (2)
1, a kind of nest plate heat radiation tube electric heater of colding pressing, this electric heater comprises " U " shape tubular type electrothermal tube (1), it is characterized in that in the outside of electrothermal tube (1), from top to bottom runs through and the uniform fin of level (2).
2, the nest plate heat radiation tube electric heater of colding pressing according to claim 1 is characterized in that on the fin (2) punching being arranged, the lotus shape fin (3) that upside forms around the punching mouth electrothermal tube (1) of filling the span of a man's arms tightly, and be the tight fit shape.
