Abstract
The invention discloses an immersive coil heat-exchanger which comprises a heat exchange tube. A liquid baffle ring inclining towards the same direction is arranged on the inner wall of the heat exchange tube; the heat exchange tube is coiled in a ring shape; the liquid baffle ring is circularly arranged on the inner wall of the heat exchange tube; the liquid baffle ring is spirally arranged on the inner wall of the heat exchange tube, and the height of the liquid baffle ring is 1/5 of the inner diameter of the heat exchange tube. The immersive coil heat-exchanger can continuously change the fluid flow direction in the heat exchange tube, so that the liquid can uniformly contact the heat exchange tube, and meanwhile, the retention period of liquid in the heat exchange tube is prolonged, and the heat exchange efficiency is also improved.
Description
Technical field
The present invention relates to submerged coil heat exchanger, belong to field of heat exchangers.
Background technology
Submerged coil heat exchanger is one of dividing wall type heat exchanger kind with the heat exchanger of coiled pipe as heat transfer element.This is a kind of ancient heat transmission equipment.It is simple in structure, and manufacturing, installation, cleaning and easy to maintenance are cheap, is specially adapted to cooling, the condensation of high-pressure fluid again, so the modern times still are used widely.But the volume of coil heat exchanger is big, heavy; Unit heat transfer area metal consumption is many, and heat conductive efficiency is low.Traditional heat exchanger tube, liquid flows in pipe, the liquid that contacts with tube wall; Can all contact with tube wall with distance is interior in the long time, when the heat gap of liquid outside liquid in pipe and the pipe was more and more nearer, exchange velocity will reduce; And the liquid on the interior center line of pipe is in a very long time and distance; Can not contact with tube wall, exchange heat can only rely on fluid exchange, and exchange efficiency is low.
Summary of the invention
In order to solve the low problem of traditional submerged coil heat exchanger heat conductive efficiency, the invention discloses the high submerged coil heat exchanger of heat transfer efficiency.
Submerged coil heat exchanger comprises heat exchanger tube, and said heat exchanger tube inwall is provided with the liquid retaining ring towards inclined, and heat exchanger tube coils ringwise.
Said liquid retaining ring is that round is arranged on the inwall of heat exchanger tube.
Said liquid retaining ring is that helical form is arranged on the inwall of heat exchanger tube.
The height of said liquid retaining ring is 1/5 of a heat exchanger tube internal diameter.
Part flow regime when liquid retaining ring of the present invention can change liquid and in heat exchanger tube, flows makes the inside and outside liquid heat exchange of pipe abundant, improves the heat transfer efficiency.
Description of drawings
Fig. 1 is a structural representation of the present invention,
Fig. 2 is the longitudinal sectional drawing of heat exchanger tube of the present invention,
Fig. 3 is that liquid flows to sketch map in heat exchanger tube of the present invention,
Accompanying drawing is indicated tabulation: 1-heat exchanger tube, 2-take over 3-liquid retaining ring.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment, further illustrate the present invention.
Fig. 1 is a structural representation of the present invention, from figure, can see that this submerged coil heat exchanger comprises heat exchanger tube 1, and heat exchanger tube 1 coils ringwise, and heat exchanger tube 1 first end is provided with heat exchanger tube and takes over 2.
Fig. 2 is the longitudinal sectional drawing of heat exchanger tube of the present invention, from figure, can see that heat exchanger tube 1 inwall is provided with the liquid retaining ring 3 towards inclined, and liquid retaining ring 3 is arranged on for round on the inwall of heat exchanger tube 1, and the height of liquid retaining ring 3 is 1/5 of heat exchanger tube 1 internal diameter.Liquid retaining ring 3 is arranged on heat exchanger tube 1 inwall, is not limited to this figure, and liquid retaining ring 3 also can be arranged on the inwall of heat exchanger tube 1 for helical form.The thickness of liquid retaining ring 3 is slightly thicker than wall thickness, and heat exchanger tube 1 inside and outside heat also can transmit through liquid retaining ring 3, and the material of liquid retaining ring 3 is identical with heat exchanger tube 1; Be the very high metal material of heat transfer efficiency, the heat transfer efficiency of heat exchanger tube 1 and liquid retaining ring 3 is all big than water, and the heat of the inside and outside liquid of the pipe of traditional heat exchanger tube 1 is only through the tube wall transmission; The inside and outside heat of the pipe of this heat exchanger tube transmits through tube wall; Simultaneously liquid retaining ring 3 also can transmission heat, makes the zone of exchange heat wider, at the pipe middle part heat transfer medium of accelerating exchange heat is arranged also; Improved the liquid heat exchange efficient at pipe middle part, let in the pipe heat or cool sooner more equably and the outer Medium Exchange of pipe.
Fig. 3 is that liquid flows to sketch map in heat exchanger tube 1 of the present invention, and overall liquid in pipe flow direction is identical with the incline direction of liquid retaining ring 3, and the flow direction of liquid when flowing through liquid retaining ring 3 positions changes and be very complicated; On the diverse location of contact liquid retaining ring 3 and with liquid retaining ring 3 top different distance on the flow direction of liquid change all inequality, but on same heat exchanger tube 1 cross section, main flow direction has two strands; From figure, can see, be denoted as current a and current b in the drawings, when current a also flows forward in the center with two strands of main flow directions on the cross section; Current b flows forward in border area in heat exchanger tube, when current a flows to liquid retaining ring 3 tops forward, can gone inspiration to go; Changed the flow direction of current a, current a flows to the vacuum area of liquid retaining ring 3 and the formation of heat exchanger tube 1 inwall, after current a flows to this vacuum area; Vacuum expendable pattern, current a is under the drive of whole current and under the promotion of rear portion current; Flow forward in the border area, flow in the time of will contacting liquid retaining ring 3 forward, the flow direction is changed; Current a upwards flows along liquid retaining ring, and under the effect of inertia at upper reaches, when flowing to liquid retaining ring 3 tops; Taking advantage of a situation flows to the center of heat exchanger tube 1, and current a flows forward in the center, when flowing to next liquid retaining ring 3 tops; Can be gone by liquid retaining ring 3 and the vacuum area inspiration that heat exchanger tube 1 inwall forms, flow down thereby circulating like this toward ground return.On the cross section identical with current a, as current a during in the center, current b is in the border area; Current a and current b all flow forward, and when current a flow to liquid retaining ring 3 tops, current b flow to the top of liquid retaining ring 3 from the bottom of liquid retaining ring 3; Current a flows to the vacuum area of liquid retaining ring 3 and the formation of heat exchanger tube 1 inwall, and current b takes advantage of a situation and flows to the center, and current a flows forward in the border area; Current b flows forward in the center, flows forward circularly then like this.Liquid retaining ring 3 has increased liquid uniform heat exchange in the heat exchanger tube 1 through changing the flow direction of heat exchange liquid in pipe circularly, has also prolonged the flowing time of liquid in heat exchanger tube 1 simultaneously, improves heat exchange efficiency.
