Abstract
The utility model discloses a heat-exchanging tube for evaporator, which comprises a tube body with cavity. The tube body outside provides spiral fins, and the cavity wall of the tube body also provides spiral screwed slots. The slot channels are formed between every two adjacent fins And the fin tops are positioned on upper part of the fins, and the fin roots are positioned on the bottom of the fins. The fin top is wider than the fin root. The laterally-projecting & intermittently-distributed inner fins are positioned between fin tops and fin roots. The added inner fins can provide larger heat-exchanging area. Meanwhile, corner meniscus formed between inner fins and wall faces and meniscus between fin roots and wall faces can be utilized to accelerate the liquid film flowing during the course of liquid going into the slot channels after exercising steam bubble separation. The existence of the inner fins can increase vaporization cores and accelerate steam bubble separation speed, so that the target of improving boiling coefficient can be reached.
Description
Technical field
The utility model relates to a kind of evaporimeter heat exchanger tube.
Background technology
The evaporimeter heat exchanger tube is the vitals in the evaporimeter, and it is made of tube wall and its tube chamber that is surrounded.Heat exchanger tube is immersed in the fluid working substance, and hot fluid flows through in pipe, produces heat-exchange tube with the fluid of managing the outside and makes outer fluid seethe with excitement, and heat exchanger tube efficient is directly determining the heat exchange effect of evaporimeter.Normally used body adopts the T fin structure, and the fin of pipe outer wall side is that spiral distributes, and forms the liquid inlet channel between the adjacent fins, and the inside pipe wall side is the screw thread conduit of helicitic texture, forms tube chamber.This T shape structure heat exchanger tube can be stable generation gasification core, can the attenuate bubble growth after the thickness of liquid film of liquid and tube wall, improved boiling heat transfer coefficient to a certain extent, it is still relatively poor to conduct heat.
Summary of the invention
The purpose of this utility model provides a kind of evaporimeter heat exchanger tube, makes heat exchanger tube boiling heat transfer efficient further improve.
A kind of evaporimeter heat exchanger tube, it comprises the body with inner chamber, the outside of described body has spiral helicine fin, also has spiral helicine thread groove on the internal chamber wall of described body, form conduit between described two adjacent fins, the top of described fin has the wing top, and the bottom of described fin has the wing root, described wing top width has inner fin interrupted distribution and that side direction is given prominence in described wing root between described wing top and the wing root.
Distance between described adjacent two fins is called fin pitch F, and its numerical value is the 0.45-0.55 millimeter.
Height between described fin pushes up from the wing root to wing is called fin height B, and its numerical value is the 0.55-0.75 millimeter.
The length H that the side direction of described inner fin is outstanding is the 0.1-0.15 millimeter.
The number of channels of the thread groove of stating on a circumferencial direction is the 10-50 bar.
The described thread groove degree of depth is groove depth C, and C is the 0.3-0.5 millimeter.
Described thread groove has spiral angle G, and this angle is the 40-50 degree.
The utility model compared with prior art has following advantage:
Owing to increased inner fin, so more heat exchange area is provided, utilize the inner fin and the meniscus of the angular region between wall and the meniscus of wing root and wall formation that generate simultaneously, behind the steam bubble lift-off, quickened liquid film in the liquid inlet channel process and flowed; Owing to there is inner fin, increased the nucleus of boiling, quicken the lift-off speed of steam bubble, thereby reached the purpose that improves boiling heat transfer coefficient.And because inner fin so increased the 3-D effect of fin, has improved the heat exchange effect along being discontinuous circumferentially.Because the tube cavity wall is provided with many thread grooves, produce circumferential rotatablely moving when making in the pipe hot fluid flow, attenuate boundary layer thickness, strengthened the heat exchange of tube cavity wall.
