Description
Technical field
The utility model relates to a kind of spiral screw thread winding type heat exchanger, belongs to pipe shell type heat exchange device field.
Background technology
Traditional shell-and-tube heat exchanger causes heat exchanging corner many because cold and hot medium import and export angle design is unreasonable, and flow path resistance is large, and heat exchange area is little, and because heat exchanger tube is generally unidirectional winding, affects heat exchange efficiency and affects service life of heat exchanger.
The utility model content
The technical problems to be solved in the utility model is: provide a kind of simple in structure, easily realize, and can improve the spiral screw thread winding type heat exchanger in heat exchange efficiency and service life.
the utility model is that the technical scheme that its technical problem of solution adopts is: described spiral screw thread winding type heat exchanger, comprise shell and the shell end socket that is arranged on the shell two ends, one end of shell is provided with position symmetrical heating agent import and refrigerant exit, the other end is provided with position symmetrical heating agent outlet and refrigerant import, screw is set in shell is wound around tube bank, the two ends that screw is wound around tube bank connect respectively advancing of heating agent, outlet, it is characterized in that: the winding direction that screw is wound around tube bank is two-way winding, and the winding direction that the screw of adjacent two layers is wound around tube bank is opposite, angle between heating agent outlet and refrigerant import is set to 86 °～96 °, angle between heating agent import and refrigerant exit is set to 86 °～96 °.
Screw is wound around tube bank and is multilayer, and winding direction is two-way winding, and the winding direction of adjacent two layers is opposite, can increase heat exchange area, improves heat transfer effect; Angle between heating agent outlet and refrigerant import is 86 °～96 °, and the angle of heating agent import and refrigerant exit is 86 °～96 °, and the setting of this angular range can reduce heat exchanging corner, improves heat transfer effect, and extends the service life of heat exchanger.
Angle between described heating agent outlet and refrigerant import is set to 90 °, and the angle between heating agent import and refrigerant exit is set to 90 °.Angle between angle, heating agent import and refrigerant exit between heating agent outlet and refrigerant import is selected the preferential scheme of selecting of 90 ° of conducts, and maximizing reduces heat exchanging corner, improves heat exchange efficiency.
The outer wall of each heat exchanger tube that described screw winding pipe is intrafascicular is provided with the U-shaped groove of helix.The helix groove is set on the heat exchanger tube outer wall, can increases the turbulivity of shell side inner fluid, increase the heat exchange amount, improve heat transfer effect.
Described shell end socket is oval shell end socket.Oval shell end socket can increase heat exchange area, reduces heat exchanging corner, improves heat exchange efficiency.
The beneficial effects of the utility model are:
Simple and reasonable; The heat exchanger tube of two-way winding can increase heat exchange area, improves the heat exchange amount; The setting of hot and cold matchmaker's import and export angle can reduce heat exchanging corner, improves heat exchanger service life; Oval shell end socket can increase heat exchange area, reduces heat exchanging corner, improves heat exchange efficiency; The setting of the U-shaped groove of helix can increase the turbulivity of shell side inner fluid, increases the heat exchange amount, improves heat transfer effect.
