Abstract
The utility model belongs to the technical field of heat transfer device and specifically relates to a carborundum screwed pipe, including the parent tube, parent tube periphery spiral winding is provided with the fin. The thickness of the fins decreases from one side close to the base pipe to one side far away from the base pipe. The axial included angle between the fins and the base pipe is 45 degrees. The utility model discloses an effect that has does the utility model discloses a spiral sets up the fin and can make flame or flue gas or other medium along the rotatory flow of fin spiral when increasing heated area, has increased vortex nature to heat exchange efficiency has been improved by a wide margin. In addition, the fins adopt a structure with a thinner thickness, so that the connection strength between the fins and the base pipe can be improved, the overall structure strength is improved, and the purpose of enabling smoke dust to be not easily gathered on the fins can be achieved.
Description
Technical Field
The utility model belongs to the technical field of heat transfer device and specifically relates to a carborundum screwed pipe.
Background
At present, advanced burners are adopted in combustion devices such as kilns and boilers to improve the combustion completeness, so that the combustion efficiency is improved, and the air-fuel ratio is greatly improved. However, when the combustion rate is improved, the waste heat recovery technology to the flue gas is not matched with the waste heat recovery technology, the ceramic heat exchange tube with a simple structure is still used for recovering the flue gas waste heat in the prior art, the recovery rate is not high, the traditional metal heat exchange tube is provided with fins along the axial direction or the radial direction for improving the heat exchange efficiency, the heating area is increased through the fins, but the fins block the flow of the flue gas or the heat flow, so that the heat exchange is limited, and the effect is not ideal.
Therefore, it is important to invent a silicon carbide threaded pipe for heat exchange which can overcome the above disadvantages.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects, the utility model provides a carborundum screwed pipe reaches through setting up spiral fin and both increases the heated area and can guide the heat flow to flow and improve heat exchange efficiency again.
The utility model provides a technical scheme that its technical problem adopted is:
the utility model provides a carborundum screwed pipe, includes the parent tube, the parent tube periphery spiral winding is provided with the fin.
As a preferred scheme of the embodiment of the utility model, the fin is by being close to one side of parent tube is to keeping away from the direction thickness of parent tube one side steadilys decrease.
As a preferred scheme of the embodiment of the utility model, the fin with the axial contained angle of parent tube is 45.
As a preferred scheme of the embodiment of the utility model, the width of fin with the external diameter of parent tube than is 0.16 ~ 0.2.
As an optimized scheme of the embodiment of the utility model, the fin is by being close to the thickness of one side of parent tube with keep away from the ratio of the thickness of parent tube one side is 1.3 ~ 2.
The utility model discloses carborundum screwed pipe can be used to heat exchanger, air cooler or evaporation air cooler.
Compared with the prior art, the utility model has the advantages of it is following and outstanding effect:
the utility model discloses a spiral sets up the fin and can make flame or flue gas or other medium along the rotatory flow of fin spiral when increasing heated area, has increased vortex nature to heat exchange efficiency has been improved by a wide margin. In addition, the fins adopt a structure with a thinner thickness, so that the connection strength between the fins and the base pipe can be improved, the overall structure strength is improved, and the purpose of enabling smoke dust to be not easily gathered on the fins can be achieved.
