Description of the Invention: Field of the Invention The present invention relates generally to a tool for forming a projection on the inner side surface of the heat exchange tube, and a method of using the tool. [Prior Art] The present invention relates to a heat exchange tube having a reinforced interior surface that facilitates transfer of heat energy from one end of the tube to the other. Heat exchange tubes are commonly used in equipment such as, for example, submerged evaporators, falling film evaporators, spray evaporators, absorption refrigerators, condensers, direct expansion coolers, and single phase coolers and heaters, Used in the refrigeration, chemical, petrochemical and food processing industries. _ Various heat exchange media can be used in these applications, including (but not limited to) pure water, water and butanediol, any type of coolant (eg r_22, R-134a, R-123, etc.), Ammonia, petrochemical liquids and other mixtures. An ideal heat exchange tube would allow a completely unobstructed flow of heat from the inside of the tube to the outside of the tube, and vice versa. However, any flow of thermal energy across the tube would normally be hampered by heat exchange resistance. . The overall resistance of the tube to heat exchange is calculated from the sum of the impedances from the outside to the inside of the tube, and vice versa. In order to improve the heat exchange efficiency of the tube, the tube manufacturer has found a way to reduce the overall impedance of the tube. Such means may enhance the outer surface of the tube, such as forming a tab on the outer surface. Due to the recent enhancement of the outer tube surface (see, e.g., U.S. Patent No. 5,697,43), only a small portion of the overall tube impedance is attributed to the outside of the tube. For example, a typical vapor tube is used in an immersion chiller with a reinforced external surface, but a smooth internal surface typically has a 10: i internal impedance to external impedance ratio. Ideally, it is generally expected to achieve an internal to external impedance ratio of i:i. Therefore, it is important to improve the overall development of the inner surface of the tube, which will significantly reduce the impedance of the tube side while enhancing the overall heat exchange presentation of the tube. Learn to provide heat exchange tubes with alternating grooves and bulges on their internal surfaces. The grooves and projections cooperate to enhance the perturbation of the liquid heat exchange medium, such as the transfer of moisture within the tube. The disturbance increases the mixing of the liquid, approaching the surface of the inner tube, reducing or virtually ignoring the boundary of the liquid medium adjacent to the inner surface of the tube. The thermal p of the boundary layer is significantly degraded by the heat exchange of the heat exchange impedance of the tube by increasing AUCE-D\PATENT\PU-069-0002 5 1291905. The grooves and projections also provide an additional surface area for additional heat exchange. This basic premise is discussed by U.S. Patent No. 3,847,212, by Withersjr et al. The pattern, shape and size of the grooves and protrusions on the inner tube surface can be changed to further enhance the heat exchange. Regarding the end, the tube manufacturer has already paid a huge fee for the experimental alternative design, including those disclosed in U.S. Patent No. 5,791,405, issued by Takima et al.; U.S. Patent Nos. 5,332,034 and 5,458,191, by Chiang U.S. Patent No. 5,975,196, issued to Gaffaney et al. In any event, in general, it has been confirmed that reinforcing the inner side surface of the tube is more difficult than the outer side surface. Furthermore, the inner and outer surfaces of the tube are mostly reinforced by casting or shaping the surface. In any case, the effect of strengthening can be achieved by cutting the surface of the tube. The patent application No. 09108759 discloses a tool for concentrating blades, which cuts a continuous spiral groove directly on the inner side surface of a tube. Similarly, Japanese Patent Application No. 10281676 discloses that the tube extension plug is equipped with a miscellaneous fastener, the inner surface of the tube is cut - a continuous spiral slit and a straight flap. U.S. Patent No. 3,753,364 discloses the use of a cutting tool along the inner side surface of the tube to form a continuous groove that is cut into the side tube surface while folding the material upward to form the continuous groove. The manufacture of heat exchange tubes using known cutting tools is a delicate and costly effort. In general, these tools are combined with cutting edges that are often exposed. As such, when these tools enter the tube, they are easily damaged. In addition, when the flashing phenomenon stops and then restarts, the tool of the name may also cause damage. These tools typically do not move at the groove and occur between the concave portion of the battalion and the smooth portion. When the tool described above forms the desired surface on a heat exchange tube, there is still a need in the industry to modify known tools by modifying existing tools and to create new tools to enhance the presentation of heat exchange. As described below, Applicants have developed various new types of tools that form a surface on the heat exchange tubes that significantly improves the appearance of the heat exchange tubes. SUMMARY OF THE INVENTION The present invention provides a modified J1 tool, and at least in the above reference application (ie: immersion evaporation S, reduction nu, H, Confucian evaporation II, hetero-cold, condenser, direct expansion ALICE-D\ PATENT\PU-069-0002 6 1291905 Expansion coolers and single-phase coolers and heaters used in the refrigeration, chemical, petrochemical, and food processing industries to enhance the heat exchange presentation of the tube. Increasing the _ surface of the tube has a number of more than a number of protrusions, which reduces the impedance of the tube side, and presents a heat exchange with the shoddy overall. According to the formed protrusion of the present invention, she has a simple protruding tool along which the surface area is formed more than five times. Some specific implementations of the present invention include a tool that can be easily attached to an existing manufacturing assembly having a cutting edge for cutting through the surface of the tube while a rising edge lifts the surface of the tube Forming a protrusion. In this way, the protrusion is formed without removing the metal by the inner side surface of the tube, whereby the debris of the assembly is damaged when the tube is used. Other embodiments of the invention include four pieces as the surface of the cutting-tube. • The tool includes a tool shaft and a tip formed at least by a first plane, a second plane, and a third plane, and having a cutting edge and a rising edge. • Other embodiments of the invention include a harness as the inside surface of the cutting-tube. The tool includes at least one cutting bit having a tool shaft, and a tip formed at least by a first plane, a second plane, and a third plane, and having a cutting edge and a rising edge. The fixture also includes an outer casing. When not in use, the cutting head can be received into the outer casing. Other embodiments include a method of increasing the inner side surface of the tube. The method includes installing one, disengaging in the tube, and disengaging the book relative to the axis and moving relative to the axis between the tube and the guard, at least the cut portion passes along the surface of the tube The formed at least one protrusion forms a raised layer and the raised layer is raised to form a protrusion. Preferably, the tool includes a tool shaft and the cutting bits are formed by interlacing the first plane, the second plane, and the third plane, while having a cutting edge and a rising edge. In a particular embodiment, the cutting edge is staggered by the first and second planes. In another embodiment, the rising edge is formed by the first and third planes being staggered. In still another embodiment, the second plane has an angular orientation with respect to a plane perpendicular to the tool axis. In a particular embodiment, the second plane has a -4 相对 relative to a vertical tool = plane 丄. To 7 〇. The angular orientation between the two. The second plane is oriented at a more specific embodiment of the λ angle such that the trimmed sheet, by bulging at 1291905 on the surface of the tube, presents approximately 2q% 5g relative to the plane of the axis of the vertical cylinder. Angle. Still in another embodiment, 'relatively perpendicular to the plane of the tool axis, oriented at an angle - a plane. In a particular embodiment, the relative milk is perpendicular to the plane of the tool shaft to a positive 45. The angle between the orientations is oriented to the third plane. ,. In an advanced embodiment, the cut edge sheet is on the inside surface of the tube by 20. An angle of between 50 produces a majority of protrusions. In a particular embodiment, the rising edge, relative to the plane perpendicular to the official plane, lifts a plurality of protrusions. In the more specific implementation, the 4 rising edge is relatively perpendicular to the plane of the guard axis to be nearly negative 45. It is positive 45. Between the angles, lift the protrusion. _ Ά In a particular embodiment, when the inner surface of the tube is cut using the tool, the J1 wire is rotated toward the ground. In the _ more specific concrete patch, between the tube and the tool $ between the relative lying 'and the axis movement, at least - a cutting _ _ shell outwardly turned in another embodiment, stop The relative rotation and relative axial movement between the tube and the tool causes at least one of the cutting bits to be retracted inwardly into the housing. In another embodiment, the cut edge sheet is 20. To 50. The angle between the two sides is raised through the inner surface of the tube to produce a township number. In the -tex body patch, the rising edge is raised relative to the plane of the 4-tube warp axis, and the protrusion is lifted at an oblique angle. In a more specific embodiment, the rising edge has a plane of -45 relative to the plane of the tube warp axis. Lift the protrusion from the angle of 45. _ [Embodiment] In order to increase the surface area of the inner diameter of a heat exchange tube, a pattern can be formed on the inner surface of the tube.

Months include four cutting bits (2). As shown in the third figure, the cutting bit (28) is fixed in a suitable position by a partial ring (2〇). The ring (2〇) also fixes the cutting bit, close to the rotating shaft ((4) such as a bone moving surface. The guard (1〇) further includes a magazine (24) for telescopically cutting the cutting bit ( 28) The spring (24) may be a leaf spring, a circular spring or a coil spring. One skilled in the art will appreciate that any compressible and extendable material, such as rubber, may be used in place of the spring (24). The spring (24) is preferably separated from the cutting bit (28) by a washer (22) that allows the spring (24) to apply pressure evenly on the bit (2)) without slipping beyond the cutting Cut the drill bit (28). A spacer (18) can be used to prevent the pressure generated by the coil spring (24) from damaging the outer casing (12). A bendable or sloping spacer (18) is placed in contact with the cutting bit (2) along the surface. This feature maintains the cutting bit (28) in an appropriate position while securing the sliding face of the cutting bit (28) adjacent the shaft. Screws ((6) will be used (set on the shaft (14). 操作 Use the screw to operate the largest diameter so that the cutting bit (2)) is exposed from the housing. In some implementations, the screw (16) is finally worn. The screw (I6) can be regarded as a method of adjusting the diameter of the largest cutting bit. Place the curved spacer (1)) between the screw ((6) and the cutting bit (28), Such a screw 〇 6) can apply pressure without damaging the cutting bit (28). When the tool (10) is not in use, the outer casing (12) protects the cutting bit ((8). In addition, the outer casing (9) cooperates with the ring (20), the spacer (8) and the screw cymbal 6 to secure the drill bit (28) in place. In some specific implementations, the outer casing consists of _separated portions (56), (58). This allows easy access to the individual tool components. It also allows different cutting bits (28) to be used in an individual (ig). For example, a cutting bit (28) with a pointed tip is attached with a special shape that can be used for a period of time, and then in the same guard ((1)), a cutting tip with a special profile can be used (28) . When the two-part housing 〇 2) is used, it can be easily replaced when the cutting bit (28) is damaged or worn. During the manufacture of Tan You-Chi Fu (62), tools can be used ((6) to cut through the bulge and lift the final raised layer to form a protrusion. The tool (1〇) includes the cutting program (28), It can be stretched and retracted in the outer casing (12). The cutting bit (28) can be made of any material with the whole structure, resisting metal cutting (for example, steel, carbide, pottery, etc.), but finally by a 9 Eunice 200APU «^^9^9-0002^9-000^ 1291905 Made of carbide. _ Cutting bit (28) - a specific embodiment, as used in the fourth to fourth. The cutting bit (10) For example, the fourth figure _:, usually has the -axis q, the two base walls (9), (6) and the _ = wide are formed by one of the side walls (9) of the cutting bit (10). However = ;! , ^nWnnmZll _ W (30) 'At the same time such a structure is not intended to limit the exposure of the fourth to fourth c. The skill of this field will be able to understand the geometry of each tip (3〇), in-single cutting bit (3), the same tip (9) is not needed. Conversely, n) having different geometries will form protrusions with different shapes and orientations, and also can be cut in the drill. Additional geometry is provided on the head (10). Furthermore, many cutting bits (28) can be used with the Guard, depending on the expected peak ρ & ρ of the protrusion. Each of the tips (9) of the cutting bit (8) is formed by staggering the planes A, B and c. Plane A and plane B are interlaced with _ edges (32), and their ruins are shouted to form a raised layer. The layer B has a (four) degree orientation with respect to a plane perpendicular to the tool axis q. (4) (9) Θ). So (10) is best between 4〇. _7(). Between, it is allowed to cut the edge sheet to approach 2 inches. The expected angle 0 of -50 passes through the bulge. A rising edge (9) formed by the interlacing of plane A and plane C, which lifts the raised layer to form a protrusion U defined by plane C and the plane is perpendicular to the guard axis q to determine the tilt angle 〇, which is between Between the _s vertical plane of the tube and the longitudinal axis of the protrusion, the protrusion is lifted by the rising edge (34). The angle is 〇, so the limb (1) on the cutting bit (8) can be directly adjusted, affecting the inclination angle of the protrusion... The inclination angle ^ (and the angle A) is preferably _8 with respect to the vertical plane of the tube (6), with _ 45. To 45. Ship dragon between any angle. In this way, the projections can be aligned with the plane of the miscellaneous s of the tube. Furthermore, the central end can be formed to have a different geometry 'so that the protrusions can have different angles of inclination (or not completely different) within the tube, and in different directions relative to the longitudinal axis of the tube s Vertical plane. Although the physical quantity of the protrusion has been confirmed to have a better range of values, one of the techniques in this field can be forcibly modified to modify the physical quantity of the cutting bit (28), affecting the final protrusion 10 200APU CASE \PU-069\PU-069-0002\PU-069'0002-3~(Ori-AUce)-2007-08-16.Dotl Amend the physical quantity of the 1291905. For example, the depth 1 is the _ of the slanted edge of the cutting edge (9) and the angle ep of the horn. Therefore, the expression can be reduced by the height of the protrusion ^ : ep = t / sin (90 ^) or assumed ¢) == 90-0, ep = t / sin ( 〇 ) where:

In any case, pay attention to the application surface of the tube to provide a beautifying effect. (9) Straight to the method of reinforcing the inner surface of the tube (62), a mandrel shaft is placed into the tube (62) +. The tool (5) is also installed in On the shaft (14). Use screws or set screws (8) to secure the tool (10) to the rotating position by any suitable method; position. Rotate. The tube (10) usually rotates = out = force. Under the force, the wall (68) The metal falls into the rib disk (the groove between (4) forms a fin on the outer surface of the official (62). The guard (10) uses the friction of the flash phenomenon in the range of the outer casing (9) The cutting bit (28) is pushed in. When the arbor (6 〇) is used, the pressure is output relative to the tube wall (68). The friction is generated by the pressure, which is opposite to the tube (6). Movement of the tool (10) creates an axial force on the spacer (18) that rapidly advances the cutting bit (28) and compresses the spring (24). When the force is relaxed, that is, when the machine is stopped, The spring (8) (4) residual bit (28) is retracted into the housing (12). A reflected image of the expected internal surface pattern is provided on the mandrel (66) so that when the tube (62) engages the mandrel (66), the mandrel (66) The inner surface of the tube (10) having the pre-face will be formed. An intended inner surface pattern includes protrusions. After the protrusions on the inner surface of the tube (62) are formed, the tube (62) is in contact with an adjacent tool (1). And moving to the rear mandrel (66). As described above, the tool (1) cuts the cutting edge (32) of the drill bit (28), and cuts the convex layer by the protrusion. Then the tool (10) The cutting edge of the cutting bit (28) raises the raised layer to form a protrusion. When the protrusion is formed while fixing the outer rib and the tool (10) (ie, does not rotate or move axially), the tube (62) automatically rotates and has an axis to move. In this example, the axial pitch of the protrusion Pap is determined by the following formula Count:

The number of fins that are activated for the outer diameter on the tube; and Zj is the number of tips on the tool. In order to obtain a specific protruding axial pitch Pap, the tool (1〇) can also be rotated. Both the tube (62) and the tool (10) can be rotated in the same direction, or both the tube (62) and the tool (1) can be rotated, but rotated in opposite directions. In order to obtain a predetermined axial pitch P 必要 the necessary rotation of the tool (10) (in units of revolutions per minute (RPM)), the following formula can be used to calculate the RPM =. tube {Pa , o * Zo - Pa^i) tool - where: RPMtube is the rotation frequency of the tube;

If the result of this calculation is negative, then the tool (10) should be the same direction of rotation as the tube (62) in order to obtain the expected pitch Pap. Or if the result of this calculation is positive, then the tool (10) should be rotated in the opposite direction to the tube (62) to obtain the expected pitch Pap. Note that the formation of the projections is performed in the same operation as the formation of the projections, and the projections are formed by the flaps in a different operation by using a tube and the previously formed internal projections. This typically requires a component to rotate the tool (10) or tube (62) and move the tool (1〇) or tube (62) along the tube axis. Furthermore, it is preferable to provide a support for concentrating the tool (1 〇) with respect to the inner tube surface. In this example, the axial pitch Pa,p of the protrusion can be calculated from the following formula:
