Abstract
The utility model relates to a kind of high-effect energy-saving heat-exchanger, comprise several heat exchanger tubes being converted into U-shaped and several plates, described heat exchanger tube layout from top to bottom in column, described plate has the hole coordinated with heat exchanger tube, described some plates are enclosed within heat exchanger tube evenly and at intervals, the cross sectional shape of heat exchanger tube is oval, the transverse of heat exchanger tube: minor axis >=1:2.Compared with the existing technology, this heat exchanger good effect of heat exchange, heat exchange efficiency is high, and compare existing heat exchanger and improve about 30%, heat exchanger structure is compact, and heat exchange area increases, and unit volume heat exchange amount is large for the utility model.
Description
Technical field
The utility model relates to a kind of heat exchanger, particularly a kind of high-effect energy-saving heat-exchanger.
Background technology
Usually, heat exchanger is the parts be used in thermal cycle, and heat exchanger can serve as condenser or evaporimeter, carries out heat exchange to make the cold-producing medium that wherein flows and external fluid.
Heat exchanger is divided into plate type heat exchanger and shell-and-tube heat exchanger.Shell-and-tube heat exchanger is classified according to enhanced heat exchange, is divided into again bellows, screwed pipe, finned tube, pipe with wound fin and profile of tooth pipe etc.These schedule of reinforcements mainly by single for heat exchanger tube strengthening, are then put in cylindrical shell and form shell-and-tube heat exchanger.But this kind of heat exchanger heat exchange area comparatively light pipe heat exchanger does not increase, and heat exchange property does not have clear improvement, and heat transfer effect is poor, and heat exchanger volume is larger.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of high-effect energy-saving heat-exchanger strengthening heat transfer effect, increase heat exchange area, compact conformation.
The utility model solves the technical scheme that its technical problem adopts: a kind of high-effect energy-saving heat-exchanger, comprise several heat exchanger tubes being converted into U-shaped and several plates, described heat exchanger tube layout from top to bottom in column, described plate has the hole coordinated with heat exchanger tube, described some plates are enclosed within heat exchanger tube evenly and at intervals, the cross sectional shape of heat exchanger tube is oval, the transverse of heat exchanger tube: minor axis >=1:2.
Described adjacent plate spacing 1.4mm-1.8mm.
Described No. of plates is 450-500.
Described plate is corrugated plate, strengthens heat transfer effect further.
The beneficial effects of the utility model are: heat transfer effect be improved significantly, for same circumference, because elliptical tube actual internal area is less than pipe, if flow is constant, disturbance strengthen, pipe in heat convection strengthened; For the outer situation of pipe, from point of flow separation position and Development of Boundary Layer, Average heat transfer effect outside elliptical tube is always better than pipe, because ellipse is similar to streamlined, when plunderring outside fluid, resistance is less, allowing can improve flow velocity under identical flow resistance, thus external heat transfer also can be strengthened;
Elliptical tube flows outside characteristic is good, and when fluid is plunderred along transverse direction is horizontal, move after relative elliptical pipe burble point, the flow losses caused due to Karman vortex street in Disengagement zone undoubtedly can reduce greatly;
Heat exchanger structure is compact, and namely under identical circulation area, elliptical tube heat transfer perimeter is long, and heat exchange area is corresponding increase also, structure also allows arrange compacter, and the heat exchange amount of unit volume is increased;
The plate of this practicality adopts corrugated plate, further enhancing heat transfer effect, and No. of plates and line space design rationally, namely add heat exchange efficiency, in turn save space.
In sum, the heat exchanger good effect of heat exchange of this practicality, heat exchange efficiency is high, and compare existing heat exchanger and improve about 30%, heat exchanger structure is compact, and heat exchange area is large, and unit volume heat exchange amount is large.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
As described in Fig. 1,2, a kind of high-effect energy-saving heat-exchanger, comprise heat exchanger tube 1 and several plates 2 of several U-shapeds, described heat exchanger tube 1 layout from top to bottom in column, heat exchanger tube 1 is fixed on tube sheet 3, described plate 2 has the hole 21 coordinated with heat exchanger tube 1, some plates 2 are enclosed within several described heat exchanger tubes 1 evenly and at intervals, the cross sectional shape of heat exchanger tube 1 is oval, the transverse of heat exchanger tube 1: minor axis >=1:2, the caliber of heat exchanger tube is 7.94mm, and major axis dimension is generally 10mm, and minor axis dimension is generally 4mm.
This heat exchanger product parameters is as shown in the table:
This heat exchanger effectively improves the heat transfer coefficient of system, and its testing result is as follows:
Can be found out by the testing result of upper table, this heat exchanger is under various operating mode, and its heat transfer coefficient, on average more than 80, is obviously better than existing heat exchanger.
These are only specific embodiment of the utility model, but technical characteristic of the present utility model is not limited thereto, any those skilled in the art are in field of the present utility model, and the modifications and variations done are all within protection domain of the present utility model.
