Abstract
The utility model discloses a heat exchanger with a turbulence guiding cap, comprising a shell body, a head, a heat-exchange coil pipe, and a pipe plate, and is characterized in that in the heat-exchange coil pipe, a supporting steel wire is arranged along a coil pipe axis; the guiding cap is connected to the supporting steel wire in series. The shape of the guiding cap is a cone. Separation distance is 4-8 times longer than the internal diameter of the heat-exchange coil pipe. Meanwhile, spiral metal wires are wound on the outer wall of the heat-exchange coil pipe. A flow guide plate and a baffle plate are arranged in the shell body. Heat-transfer efficiency can be increased by 50-200%. The utility model is applied to shell and pipe type, volume type, and various types heat exchangers, and is used for a hot water supply system of construction engineering.
Description
The utility model belongs to the heat-exchange apparatus that general heat-exchange apparatus, particularly heat exchange medium directly do not contact.
At present, in the hot water supply system of industry and civil buildings, often adopt heat exchanger.Heat exchanger is that heat exchange coil in groups is set in tank-like shell, is medium with steam or high-temperature water, flows through in heat exchange coil, and heat is transferred to medium in the housing from the tube wall of heat exchange coil, realizes heat exchange.In order to improve heat exchange efficiency, can increase coil pipe quantity, increase coil lengths, but can increase the housing volume like this, the increase of heat exchange efficiency is limited.
The purpose of this utility model is, fair water cone is set in heat exchange coil, causes the turbulent flow of thermal medium, to quicken heat transfer process, further improves heat exchange efficiency.
The heat exchanger that has the turbulent flow fair water cone of the present utility model is made up of tank-like shell, end socket, heat exchange coil, tube sheet, it is characterized in that in heat exchange coil, along the coil pipe axis one supporting steel wire is set, and is serially connected with fair water cone on supporting steel wire.
Fair water cone is conical, and cone bottom diameter is 0.8 times of heat exchange coil internal diameter, and the cone height is 0.4 times of heat exchange coil internal diameter, and the fair water cone spacing is 4～8 times of heat exchange coil internal diameter size.
In order to improve heat exchange efficiency, in the housing of the heat exchanger that has the turbulent flow fair water cone, be provided with deflector and deflection plate, on the heat exchange coil outer wall, be wound with the spiral metal silk.
The heat exchanger that has the turbulent flow fair water cone can be a shell and tube exchanger, vertical volumetric heat exchanger, horizontal volumetric heat exchanger, single hole heat exchange coil heat exchanger, diplopore heat exchange coil heat exchanger.
Have the heat exchanger of turbulent flow fair water cone, have the following advantages: the disturbance when fair water cone can increase thermal medium and flows in heat exchange coil, improve the local velocity of thermal medium, produce rapid turbulent flow, strengthened heat exchange, can improve heat transfer efficiency 50～200%.Spiral metal silk on the heat exchange coil outer wall, but not only erratic flow also helps removing contamination of outer wall surface through the medium of outer wall.Under same heat exchange area condition, strengthened total heat exchange amount, can reduce the housing volume, save steel, reduce heat exchanger and take up room, have economic benefit.Fair water cone simple in structure is easy to install, and is convenient to safeguard.
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is the front view that has the heat exchanger of turbulent flow fair water cone.
Fig. 2 is that fair water cone is provided with figure in the heat exchange coil.
Fig. 3 is the B-B profile of Fig. 2.
Fig. 4 twines spiral metal silk structure chart on the heat exchange coil outer wall.
Fig. 5 is the fair water cone structural map.
Fig. 6 is the A-A profile of Fig. 1.
As seen from the figure, the heat exchanger that has the turbulent flow fair water cone is made up of housing 1, end socket 2, heat exchange coil 3, tube sheet 4, in heat exchange coil 3, be provided with supporting steel wire 5 along axis, fixing with cross steel wire 7, fair water cone 6 is conical, is serially connected on the supporting steel wire 5, spacing is 4～8 times of heat exchange coil internal diameter, on the outer wall of heat exchange coil, twine helical steel wire 10, in housing, be provided with horizontal deflector 8 and vertical baffling plate 9.Through test, the more common heat exchanger of its heat transfer efficiency improves 200%.
