Abstract
The utility model belongs to the technical field of heat exchange devices and discloses an evaporation tube for an evaporator. The evaporation tube is mainly technically characterized in that the evaporation tube comprises a copper tube body, a plurality of double-sided corrugated fins are evenly arranged on the external surface of the copper tube body, the upper parts of the double-sided corrugated fins are bent and connected with adjacent double-sided corrugated fins, the surfaces of the double-sided corrugated fins are concave-convex faces, the concave-convex faces of the double-sided corrugated fins are S-shaped, and the internal surface of the copper tube body is smooth. According to the evaporation tube for the evaporator, a series of regular channels are formed on the surface of the copper tube body, and meanwhile, even and continuous channels are formed on bent sides of the double-sided corrugated fins; due to the regular channels, a plurality of boiling nucleates can be formed by the surface of a copper tube and the double-sided corrugated fins, the continuous generation of evaporation bubbles is favored, the re-condensation of boiling bubbles can be avoided, the influence arising from a super-cooled coolant is reduced, and the excellent heat transfer effect can also be obtained in low-heat flow zones; and the heat exchange area is large, the coefficient of heat exchange is great, the water-side resistance is low, and the energy source is saved.
Description
Technical field
The utility model belongs to technical field of heat exchange devices, relates in particular to a kind of evaporimeter of large-scale refrigeration plant that is applicable to and uses evaporation tube.
Background technology
At present, the evaporator evaporation tubular construction of large-scale refrigeration plant is to be main body with the copper pipe, forms fin on the surface of smooth copper through extrusion rolling, to strengthen the heat exchange area of freon side, improves the coefficient of heat transfer.But this fin or the fin shape that forms through extrusion rolling is irregular, is difficult to the passage of formation rule between fin, and channel forming is poor; Thereby to form steam bubble few when evaporation; The coefficient of heat transfer improves not remarkable, and endoporus also is prone to distortion in the extrusion rolling process, and the water collateral resistance is increased.Some evaporation tube is further to improve the whole coefficient of heat transfer, also exchanges bigger heat-transfer surface in copper pipe inboard also rolled fin, improves the coefficient of heat transfer of water side; But; Screw thread in the pipe makes the water collateral resistance increase again, if reduce water resistance, can only reduce water speed; Can cause the reduction of the coefficient of heat transfer like this, so its effect that increases the coefficient of heat transfer is also not obvious.
The utility model content
The technical problem that the utility model solves just provides that a kind of when evaporation, to form steam bubble many, and the coefficient of heat transfer is big, and the evaporimeter that the water collateral resistance is little is used evaporation tube.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: comprise the copper pipe body, the outer surface of said copper pipe body evenly is provided with a plurality of two-sided wave-shaped fins, and the top bending of two-sided wave-shaped fins is connected with adjacent two-sided wave-shaped fins.
Its additional technical feature is: the surface of said two-sided wave-shaped fins is a male and fomale(M&F); The male and fomale(M&F) of said two-sided wave-shaped fins is the S type; The inner surface of said copper pipe body is smooth.
The evaporimeter that the utility model provided uses evaporation tube to be the main body body with copper pipe, and the outer surface of body embeds rolling two-sided wave-shaped fins in advance, and two-sided wave-shaped fins evenly distributes along copper pipe surface; The two-sided wave-shaped fins first half bends to a direction through roll extrusion, and adjacent two-sided wave-shaped fins top connects, thereby forms the passage of series of rules in copper pipe surface; On the bending edge of two-sided wave-shaped fins, form evenly continuous passage simultaneously, the passage that these are regular makes copper pipe surface and two-sided wave-shaped fins form a lot of boiling nuclears; Be beneficial to the continuous generation of evaporation steam bubble; Can avoid seething with excitement steam bubble by condensation again, reduce cold matchmaker's influence, also can obtain fabulous heat-transfer effect at low heat flow province; And the size of passage is accurate, makes evaporimeter very stable with the performance of evaporation tube.And the rolling acquisition that is mould of two-sided wave-shaped fins guarantees consistently with the fit clearance of copper pipe, and copper pipe is embedded in two-sided wave-shaped fins through the machinery pipe that rises, and the endoporus work in-process is indeformable, guarantees current not to be formed influence.The surface of two-sided wave-shaped fins is a S type male and fomale(M&F), has more increased heat exchange area, improves the coefficient of heat transfer of heat exchanger tube, reduces the power consumption of refrigeration compressor.The inner surface of copper pipe body is smooth, and promptly not rolling internal thread when keeping heat transfer property, has reduced the drag losses of water side, the energy consumption that can save the air-conditioning system water pump.The evaporimeter that the utility model provided has positive effect with evaporation tube to energy savings.
Description of drawings
Fig. 1 is the structural representation of the utility model evaporimeter with evaporation tube;
Fig. 2 is the structural representation of two-sided wave-shaped fins.
The specific embodiment
Below in conjunction with accompanying drawing structure and the use principle of the utility model evaporimeter with evaporation tube explained further details.
As shown in Figure 1; The utility model evaporimeter comprises copper pipe body 1 with evaporation tube; The inner surface of copper pipe body 1 is smooth, and the outer surface of copper pipe body 1 evenly is provided with a plurality of two-sided wave-shaped fins 2, and the top bending of two-sided wave-shaped fins 2 is connected with adjacent two-sided wave-shaped fins 2.As shown in Figure 2, the surface of two-sided wave-shaped fins 2 is a S type male and fomale(M&F) 3.
The evaporimeter that the utility model provided embeds rolling two-sided wave-shaped fins 2 in advance with evaporation tube at the outer surface of copper pipe body 1; Two-sided wave-shaped fins 2 evenly distributes along copper pipe body 1 surface; Two-sided wave-shaped fins 2 first halves bend to a direction through roll extrusion; Adjacent two-sided wave-shaped fins 2 tops connect, thereby form the passage of series of rules on copper pipe body 1 surface, and on the bending edge of two-sided wave-shaped fins 2, evenly connect.The evaporimeter that the utility model provided passes through the passage in two-sided wave-shaped fins 2 surperficial formation rules with evaporation tube; On the bending edge of two-sided wave-shaped fins 2, form evenly continuous passage simultaneously, the passage that these are regular makes copper pipe body 1 surface and two-sided wave-shaped fins 2 form a lot of boiling nuclears; Be beneficial to the continuous generation of evaporation steam bubble; Can avoid seething with excitement steam bubble by condensation again, reduce cold matchmaker's influence, also can obtain fabulous heat-transfer effect at low heat flow province; And the size of passage is accurate, makes evaporimeter very stable with the performance of evaporation tube.And two-sided wave-shaped fins 2 is the rolling acquisitions of mould, guarantees consistently with the fit clearance of copper pipe body 1, and copper pipe body 1 is embedded in two-sided wave-shaped fins 2 through the machinery pipe that rises, and the endoporus work in-process is indeformable, guarantees current not to be formed influence.The surface of two-sided wave-shaped fins 2 is a S type male and fomale(M&F) 3, has more increased heat exchange area, improves the coefficient of heat transfer of heat exchanger tube, reduces the power consumption of refrigeration compressor.The inner surface of copper pipe body 1 is smooth, and promptly not rolling internal thread when keeping heat transfer property, has reduced the drag losses of water side, the energy consumption that can save the air-conditioning system water pump.
