Abstract
The utility model relates to a screw internal tooth pipe used for oil coolers of large size transformers and other heat-exchangers in need of high efficiency, belonging to the tube of the inner face strengthened heat-exchanger. The utility model is characterized in that the screw internal tooth is arranged inside a steel tube. Capable of simplifying the production process, the screw internal tooth pipe of the utility model in the steel tube can directly change the liquor in the steel tube into the eddy flow, thereby effectively increasing the coefficient of heat transfer, raising the heat transfer efficiency, increasing the heat interchanging area, and further reducing the energy consumption.
Description
The utility model relates to a kind of spiral internal tooth pipe, is used for high-power transformer oil cooler and other need cool-heat-exchanger efficiently, belongs to inner surface and strengthens heat exchange with managing.
Before the utility model was made, in prior art, the heat exchange pipe was a straight-tooth pipe in adopting.The medium of heat exchange can only be done laminar motion in the interior straight-tooth pipe, but the laminar condition can not destroy fluid and flow in pipeline the time becomes turbulent condition for making fluid from laminar condition, just must install the water conservancy diversion silk additional.Make workpiece weight increase after adding the water conservancy diversion silk, manufacturing procedure increases, and causes the conductor flow dynamic resistance to increase, and the coefficient of heat transfer is low.
The purpose of this utility model is to overcome above-mentioned weak point, flows thereby provide a kind of direct fluid with pipeline to become turbulent condition, and the more effective raising coefficient of heat transfer, heat transfer efficiency have increased heat exchange area, and the spiral internal tooth pipe that can cut down the consumption of energy.
Main solution of the present utility model is achieved in that it mainly is made up of steel pipe 1, helical tooth 2, is shaped on helical tooth 2 in steel pipe 1.
Description of drawings:
Fig. 1 is the utility model structural front view:
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
The utility model mainly is made up of steel pipe 1, helical tooth 2.The diameter of steel pipe 1, length can be made all size according to user's needs, then the uniform helical tooth 2 of making in steel pipe 1.
Compared with the prior art the utility model has the following advantages:
Because the utility model has been made helical tooth in steel pipe, reduced production process, the pipe internal screw tooth Pipe can be directly becomes turbulent state with the fluid of pipeline and flows, and can effectively improve the heat exchange coefficient, improves Heat transfer efficiency; Increase heat exchange area, and can further reduce energy consumption; Its purposes is extensive, can extensively use In the oil cooler at high-power transformer, in the heat exchanger of the radiator of textile industry, chemical industry industry.
