Abstract
The utility model provides a heat exchanger with arc-line groove pipes, comprising a casing body, a heat-exchanging pipe, a pipe plate, a pipe box, a pipe pass inlet, a pipe pass outlet, a shell pass inlet and a shell pass outlet, wherein, the heat-exchanging pipe is arranged in the casing body through the pipe plate. The utility model is characterized in that the heat-exchanging pipe is provided with a plurality of continuous arc-line grooves, and two adjacent arc-line grooves are connected through a lug boss. Because the heat-transferring pipe is provided with the arc-line grooves, the utility model can improve the heat-transferring efficiency of a pipe heat exchanger, and the heat-exchanging efficiency can be improved by 2-4 times. The utility model also has the advantages that structure is simple, and that the outer diameter of a connecting part between the heat-exchanging pipe and the pipe plate is equal to that of the arc-line lug boss.
Description
The utility model relates to technical field of heat exchange, particularly a kind of arc groove heat exchange of heat pipe.
At present, industrial heat-exchanger rig adopts tubular heat exchanger mostly, it is mainly by housing and be arranged in the housing heat exchanger tube and form, liquid or gas are by heat transfer tube wall conduction carrying out heat exchange, tubulation in this shell-and-tube heat exchanger tube housing is the equal diameter light pipe, when liquid flows through in heat exchanger tube, on the heat exchange tube wall, form very thick boundary layer, when condensation heat transfer, when contacting with the heat exchanger tube outer wall, gas forms very thick liquid film, boundary layer or the liquid film main thermal resistance for conducting heat is so the heat transfer coefficient of shell-and-tube heat exchanger is very low at present.
The purpose of this utility model provides a kind ofly can effectively destroy the boundary layer, improves heat transfer coefficient, can increase heat exchange area again simultaneously, guarantees the tube bundle support reliability, makes the compact more arc groove heat exchange of heat pipe of equipment.
The purpose of this utility model is achieved in that it comprises that housing, heat exchanger tube, tube sheet, bobbin carriage, tube side import, tube side outlet, shell side import and shell side outlet, heat exchanger tube are arranged in the housing by tube sheet, it is characterized in that heat exchanger tube is provided with continuous a plurality of camber line groove, two adjacent camber line grooves are by the boss transition.
The utility model is owing to be provided with the camber line groove on heat-transfer pipe, so can improve the heat transfer efficiency of pipe heat exchanger, heat exchange efficiency can improve 2-4 doubly, the advantage that the external diameter that also has a part that is connected between simple in structure, heat exchanger tube and the tube sheet equates with the external diameter of camber line boss.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of arc groove heat exchange of heat pipe.
Fig. 2 is the structural representation of heat exchanger tube.
Shown in Fig. 1-2, this arc groove heat exchange of heat pipe comprises housing 1, heat exchanger tube 2, tube sheet 3, bobbin carriage 4, tube side import 5, tube side outlet 6, shell side import 7, shell side outlet 8, heat exchanger tube 2 is arranged in the housing 1 by tube sheet 3, heat exchanger tube 2 is provided with continuous a plurality of camber line groove 9, adjacent two camber line grooves 9 are by boss 10 transition, camber line groove 9 on the heat exchanger tube 2 is camber line shape or open type polygon, and the external diameter of the part that is connected between heat exchanger tube 2 and the tube sheet 3 equates with the external diameter of camber line boss 10.
