Abstract
The utility model discloses an efficient heat exchanger with corrugated heat-exchange tubes. The efficient heat exchanger comprises an upper tube plate, a shell, the corrugated heat-exchange tubes and a lower tube plate, the upper end and the lower end of each corrugated heat-exchange tube are fixedly connected on the upper tube plate and the lower tube plate respectively, each corrugated heat-exchange tube comprises a straight tube section and corrugated tube sections, each corrugated tube section is formed by connecting a plurality of crests with a plurality of troughs, the corrugated tube sections are arranged on the corresponding straight tube section at intervals, the diameters of each two adjacent crests of each corrugated tube section are different, and the efficient heat exchanger is further characterized in that the corrugated tube sections on each two adjacent corrugated heat-exchange tubes are staggered. The efficient heat exchanger with the corrugated heat-exchange tubes has the advantages that remarkable turbulence flow effect is generated by remarkable change of flowing cross-sectional area in each tube, so that media can generate the turbulence flow state at a low flowing speed instead of a high flowing speed, and heat exchange efficiency is improved remarkably; obvious washout effect can be achieved to enable scale to be reduced remarkably; and since the corrugated tube sections on each two adjacent corrugated heat-exchange tubes are staggered, the whole heat exchanger can be even in heat exchange while heat exchange efficiency can be improved remarkably.
Description
Technical field
The utility model relates to a kind of heat exchanger, particularly a kind of node heat exchanger tube heat exchanger.
Background technology
In recent years, node heat exchanger tube heat exchanger had obtained development rapidly.Node heat exchanger tube in the existing node heat exchanger tube heat exchanger comprises straight length, wave duct section, all be the wave duct section basically on the whole node heat exchanger tube, and the wave duct section is formed by connecting by isometrical crest, trough.Be unfavorable for the laminar condition that conducts heat though this node heat exchanger tube heat exchanger can destroy, be conducive to conduct heat that reduce incrustation, formed turbulent effect is not remarkable, heat exchange efficiency is not high, and the effect that reduces incrustation is also bad.
The utility model content
The utility model proposes a kind of energy and forms significant turbulent effect, heat exchange efficiency height at the deficiencies in the prior art; Can produce tangible souring, significantly reduce the heat exchanger of the efficient node heat exchanger tube of incrustation.
The utility model is achieved through the following technical solutions technical goal.
The heat exchanger of efficient node heat exchanger tube comprises upper perforated plate, housing, node heat exchanger tube, lower perforated plate; Described node heat exchanger tube upper and lower side is fixedly connected on respectively on upper perforated plate, the lower perforated plate; Described node heat exchanger tube comprises straight length, wave duct section; Described wave duct section is formed by connecting by several crests, trough; Its improvements are: described wave duct section is arranged on straight length at interval; Each described wave duct section adjacent peaks diameter is inequality.
As the preferred version of such scheme, the wave duct section on the adjacent node heat exchanger tube is staggeredly arranged.
As the further preferred version of such scheme, each described wave duct section adjacent peaks diameter successively decreases one by one.
The utility model compared with prior art has following good effect:
1. the wave duct section is arranged on straight length at interval, each wave duct section adjacent peaks diameter is inequality, marked change by passage section area in managing, produce significant turbulent effect, make medium under low flow velocity, just can produce the turbulent condition that could produce than high flow velocities, significantly improve heat exchange efficiency; Node heat exchanger tube reducing can produce tangible souring, significantly reduces incrustation.
2. the wave duct section on the adjacent node heat exchanger tube is staggeredly arranged, and not only can make whole heat exchanger heat exchange even, but also can significantly improve heat exchange efficiency.
3. each wave duct section adjacent peaks diameter successively decreases one by one, can further improve turbulent effect.
By above measure, the heat exchange efficiency of heat exchanger improves 15～20%.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the enlarged diagram of node heat exchanger tube among Fig. 1.
The specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and in conjunction with the embodiments below.
The heat exchanger of efficient node heat exchanger tube shown in the drawings comprises upper perforated plate 1, housing 2, node heat exchanger tube 3, lower perforated plate 4; Node heat exchanger tube 3 upper and lower sides are fixedly connected on respectively on upper perforated plate 1, the lower perforated plate 4; Node heat exchanger tube 3 comprises straight length 3.1, wave duct section 3.2; Wave duct section 3.2 is formed by connecting by several crests 3.2.1, trough 3.2.2; Wave duct section 3.2 is arranged on straight length 3.1 at interval; Each wave duct section 3.2 adjacent peaks 3.2.1 diameter is inequality, and in the present embodiment, each wave duct section 3.2 adjacent peaks 3.2.1 diameter successively decreases one by one.
In order to make whole heat exchanger heat exchange even, in the present embodiment, the wave duct section 3.2 on the adjacent node heat exchanger tube 3 is staggeredly arranged, and so also can significantly improve heat exchange efficiency certainly
The utility model is by the marked change of passage section area in the pipe, produce significant turbulent effect, make medium just can produce the turbulent condition that could produce than high flow velocities under low flow velocity, significantly improve heat exchange efficiency, the heat exchange efficiency of heat exchanger improves 15～20%; And can produce tangible souring, significantly reduce incrustation.
