Description

Technical Field

[0001] The utility model relates to the field of oil pipes, in particular to an oil pipe with a heat dissipation structure. Background Art

[0002] When a hydraulic system is operating, the hydraulic oil temperature rises and the viscosity decreases. This, in turn, reduces the system's compression ratio, output pressure, and front-end drive component power, leading to overload risks. Furthermore, high temperatures can exacerbate the oxidation of the hydraulic oil, causing it to lose effectiveness. Therefore, cooling the oil pipes is essential.

[0003] The current cooling method is to use a fan to blow air to cool the oil pipe, or to wrap a water pipe around the oil pipe and continuously pass cold water for cooling. The above cooling methods all require continuous energy supply and are relatively costly. Utility Model Content

[0004] In order to save the heat dissipation cost of the oil pipe, the present application provides an oil pipe with a heat dissipation structure.

[0005] The oil pipe with a heat dissipation structure provided in this application adopts the following technical solution:

[0006] 12. The heat dissipation device as claimed in claim 1, wherein the bridge has two opposite ends, and one of the ends is disconnected from the mounting plate of the heat dissipation device, and the other end is connected to the mounting plate by the bridge, to form a round shank and a cutoff point, wherein the bridge has two opposite ends, and the other end is connected to the mounting plate by the bridge.

[0007] By adopting the above technical solution, after the operator installs the heat sink fins, he fits the two heat sink arcs onto the oil pipe body, and then uses the clamps to clamp the two heat sink arcs onto the oil pipe body. At this time, the heat sink arcs can be fixedly fitted onto the oil pipe body, and the heat generated on the oil pipe body will be transferred to the heat sink arcs, and then transferred to the heat sink fins. Since the heat sink fins have a large contact area with the air, the heat sink fins can better transfer heat to the air, thereby achieving a good heat dissipation effect. At the same time, the entire process does not require energy supply, which saves costs to a certain extent.

[0008] Preferably, the limiting part includes a limiting arc block, a limiting arc groove and a locking bolt. The limiting arc groove is opened on the surface of the heat dissipation arc fin along the circumferential direction. The limiting arc groove is located at one end of the wedge-shaped groove passing through the heat dissipation arc fin. The limiting arc groove is connected to multiple wedge-shaped grooves. The limiting arc block is fixed to the heat dissipation arc fin by a locking bolt. When the heat dissipation fin is installed, the limiting arc block abuts against the end faces of multiple wedge-shaped blocks.

[0009] By adopting the above technical solution, after the limiting arc block is fixed to the heat dissipation arc plate by locking bolts, the limiting arc block is located on the moving path of the wedge block and abuts against the end of the wedge block, fixing the position of the wedge block by limiting the movement of the wedge block.

[0010] Preferably, a groove is provided on the bottom wall of the limiting arc groove, and a spring is provided in the groove. One end of the spring is fixed on the bottom wall of the groove, and the other end of the spring is always pushed out toward the side away from the groove, so as to drive the limiting arc block to disengage from the limiting arc groove when the locking bolt disengages from the heat dissipation arc plate.

[0011] By adopting the above technical solution, when the locking bolt locks the limit arc block on the heat sink arc plate, the spring abutting against the limit arc block can reduce the chance of the locking bolt loosening; when the locking bolt is removed, the spring can push out the limit arc block to help the operator remove the limit arc block.

[0012] Preferably, the groove and the spring are both arranged to be inclined toward one side of the heat dissipation fin.

[0013] By adopting the above technical solution, the elastic force of the spring pushes the limiting arc block obliquely upward toward the side of the heat sink fin. Friction will be generated between the limiting arc block and the multiple wedge blocks and the multiple heat sink fins, so that the limiting arc block will not be pushed away uncontrollably, thereby improving the stability of the disassembly of the limiting arc block.

[0014] Preferably, when the oil pipe body is in a high-temperature working state, the wedge block and the wedge groove have an interference fit, and when the oil pipe body is in a normal temperature state, the wedge block and the wedge groove have a clearance fit.

[0015] By adopting the above technical solution, when the oil pipe is working at a high temperature, the wedge block expands due to the heat, thereby achieving an interference fit with the wedge groove. The wedge block can better fit the inner wall of the wedge groove, and the temperature of the oil pipe itself can be better transferred to the heat dissipation fins through the heat dissipation arc sheet, thereby achieving a better heat dissipation effect; when the oil pipe is at room temperature, the wedge block and the wedge groove are clearance-matched, and the wedge block can better slide out of the wedge groove, which facilitates the installation and removal of the wedge block.

[0016] Preferably, the clamping member includes two first side wings, two second side wings and multiple pairs of bolts and nuts, the two first side wings are fixedly arranged on both sides of the corresponding heat dissipation arc along the length direction of one of the heat dissipation arcs, and the two first side wings are fixedly arranged on both sides of the corresponding heat dissipation arc along the length direction of the other heat dissipation arc. When the two heat dissipation arcs are installed on the oil pipe body, the two first side wings are respectively opposite to the two second side wings, and the first side wings are connected to the relative second side wings by bolts and nuts.

[0017] Preferably, among the multiple heat dissipation fins on the heat dissipation arc, the two heat dissipation fins located at the two ends are end fins, and a rotating shaft is fixed to one end of the end fin close to the wedge block. The corresponding wedge block is provided with a rotating groove that is interference fit with the rotating shaft, and the rotating shaft rotates in the rotating groove.

[0018] By adopting the above technical solution, when the first side wing and the second side wing are fixed with bolts and nuts, the end fins will affect the installation of the bolts and nuts due to their position and inclination angle. Therefore, the operator reduces the impact of the end fins on the installation by rotating the end fins toward the side away from the first side wing or the second side wing.

[0019] Preferably, an extension wing for hand force application is provided on the end surface of the end fin in the length direction.

[0020] By adopting the above technical solution, it is convenient for operators to rotate the end fins.

[0021] The technical effects of this utility model are mainly reflected in the following aspects:

[0022] 1. After the operator of the present invention has installed the heat dissipation fins, he or she fits the two heat dissipation arcs onto the oil pipe body, and then uses a clamping piece to clamp the two heat dissipation arcs onto the oil pipe body. At this time, the heat dissipation arcs can be fixedly fitted onto the oil pipe body, and the heat generated on the oil pipe body will be transferred to the heat dissipation arcs, and then transferred to the heat dissipation fins. Since the heat dissipation fins have a large contact area with the air, the heat dissipation fins can better transfer heat to the air, thereby achieving a good heat dissipation effect. At the same time, the entire process does not require energy supply, which saves costs to a certain extent.

[0023] 2. The utility model sets a spring. When the locking bolt locks the limit arc block on the heat dissipation arc plate, the spring abuts against the limit arc block to reduce the chance of the locking bolt loosening; when the locking bolt is removed, the spring can push out the limit arc block to help the operator remove the limit arc block.

[0030] The following is combined with Figure 1-5 The present application is further described in detail to make the technical solution of the present application easier to understand and grasp.

[0031] An embodiment of the present application discloses an oil pipe with a heat dissipation structure.

[0032] Reference Figure 1-Figure 3 , an oil pipe with a heat dissipation structure of this embodiment includes an oil pipe body 1 and a heat dissipation structure 2 detachably connected to the oil pipe body 1, the heat dissipation structure 2 includes a clamping member 3 and two heat dissipation arcs 21 matching the outer wall of the oil pipe body 1, the clamping member 3 is used to drive the two heat dissipation arcs 21 to clamp the oil pipe body 1, and a plurality of heat dissipation fins 22 are detachably provided on the heat dissipation arc fin 21, and a plurality of wedge-shaped grooves 211 are opened on the surface of the heat dissipation arc fin 21 along the length direction, and the plurality of wedge-shaped grooves 211 are evenly distributed along the circumferential direction, and one end of the wedge-shaped grooves 211 passes through the heat dissipation arc fin 21, and a wedge-shaped block 221 matching the wedge-shaped groove 211 is provided on the heat dissipation fin 22, and the wedge block 221 slides in the wedge-shaped groove 211, and a limiting member 4 is provided on the heat dissipation arc fin 21, which is used to limit the movement of the heat dissipation fin 22 after the heat dissipation fin 22 is installed.

[0033] Reference Figure 1-Figure 3After the operator installs the heat dissipation fins 22, the two heat dissipation arcs 21 are attached to the oil pipe body 1, and then the two heat dissipation arcs 21 are clamped to the oil pipe body 1 using the clamping parts 3. At this time, the heat dissipation arcs 21 can be fixedly attached to the oil pipe body 1, and the heat generated on the oil pipe body 1 will be transferred to the heat dissipation arcs 21, and then transferred to the heat dissipation fins 22. Since the heat dissipation fins 22 have a large contact area with the air, the heat dissipation fins 22 can better transfer heat to the air, thereby achieving a good heat dissipation effect. At the same time, the entire process does not require energy supply, which saves costs to a certain extent.

[0034] Reference Figure 1-Figure 3 If a notch appears on the heat sink 22 after being hit, the operator slides the wedge block 221 out along the wedge groove 211 and removes the notched heat sink 22 from the heat sink arc 21. If there is a heat sink fin 22 that can be replaced with a complete heat sink fin 22, the problem of irregular notches that can easily hurt people can be solved.

[0035] Reference Figure 2 and Figure 3 The limiting member 4 includes a limiting arc block 41, a limiting arc groove 42, and a locking bolt 43. The limiting arc groove 42 is formed on the surface of the heat dissipation arc fin 21 along the circumferential direction. The limiting arc groove 42 is located at one end of the wedge-shaped groove 211 that passes through the heat dissipation arc fin 21. The limiting arc groove 42 is connected to multiple wedge-shaped grooves 211. The limiting arc block 41 is fixed to the heat dissipation arc fin 21 via the locking bolt 43. When the heat dissipation fin 22 is installed, the limiting arc block 41 abuts against the end faces of multiple wedge blocks 221. After the limiting arc block 41 is fixed to the heat dissipation arc fin 21 by the locking bolt 43, the limiting arc block 41 is located in the movement path of the wedge block 221 and abuts against the end of the wedge block 221, thereby fixing the position of the wedge block 221 by limiting its movement.

[0036] Reference Figure 2-Figure 4 The bottom wall of the limiting arc groove 42 is provided with a groove 421, and a spring 422 is disposed within the groove 421. One end of the spring 422 is fixed to the bottom wall of the groove 421, and the other end of the spring 422 is always protruding toward the side away from the groove 421. This is used to drive the limiting arc block 41 out of the limiting arc groove 42 when the locking bolt 43 is disengaged from the heat dissipation arc fin 21. When the locking bolt 43 locks the limiting arc block 41 to the heat dissipation arc fin 21, the spring 422 abuts against the limiting arc block 41 to reduce the chance of the locking bolt 43 loosening. When the locking bolt 43 is removed, the spring 422 can push out the limiting arc block 41, helping the operator to remove the limiting arc block 41.

[0037] Reference Figure 2-Figure 4The groove 421 and the spring 422 are both arranged at an angle toward the side of the heat sink fin 22. The elastic force of the spring 422 pushes the limiting arc block 41 upward and obliquely toward the side of the heat sink fin 22. Friction is generated between the limiting arc block 41, the multiple wedge blocks 221, and the multiple heat sink fins 22, so that the limiting arc block 41 is not pushed away uncontrollably, thereby improving the stability of the limiting arc block 41 during removal.

[0038] Reference Figure 3 and Figure 4 When the oil pipe body 1 is operating at a high temperature, the wedge block 221 has an interference fit with the wedge groove 211. When the oil pipe body 1 is at a normal temperature, the wedge block 221 has a clearance fit with the wedge groove 211. When the oil pipe is operating at a high temperature, the wedge block 221 expands due to the heat, thereby achieving an interference fit with the wedge groove 211. The wedge block 221 and the inner wall of the wedge groove 211 can better fit, and the temperature of the oil pipe itself can be better transferred to the heat dissipation fins 22 through the heat dissipation arc 21, thereby achieving a better heat dissipation effect. When the oil pipe is at a normal temperature, the wedge block 221 has a clearance fit with the wedge groove 211, and the wedge block 221 can better slide out of the wedge groove 211, facilitating the installation and removal of the wedge block 221.

[0039] Reference Figure 1 and Figure 2 The clamping member 3 includes two first side wings 31, two second side wings 32 and multiple pairs of bolts and nuts. The two first side wings 31 are fixedly arranged on both sides of the corresponding heat dissipation arc fin 21 along the length direction of one of the heat dissipation arc fins 21, and the two first side wings 31 are fixedly arranged on both sides of the corresponding heat dissipation arc fin 21 along the length direction of the other heat dissipation arc fin 21. When the two heat dissipation arc fins 21 are installed on the oil pipe body 1, the two first side wings 31 are respectively opposite to the two second side wings 32, and the first side wings 31 are connected to the corresponding second side wings 32 by bolts and nuts.

[0040] Reference Figure 3 and Figure 5 Among the multiple heat dissipation fins 22 on the heat dissipation arc 21, the two heat dissipation fins 22 located at both ends are end fins 222. A rotating shaft 24 is fixed to one end of the end fin 222 close to the wedge block 221. A rotating groove 25 with an interference fit with the rotating shaft 24 is opened on the corresponding wedge block 221, and the rotating shaft 24 rotates in the rotating groove 25.

[0041] Reference Figure 3 and Figure 5 When using bolts and nuts to fix the first side wing 31 and the second side wing 32, the end fin 222 will affect the installation of the bolts and nuts due to its position and inclination angle. Therefore, the operator rotates the end fin 222 toward the side away from the first side wing 31 or the second side wing 32 to reduce the impact of the end fin 222 on the installation.

[0042] Reference Figure 2 and Figure 3 The end surface of the end fin 222 in the length direction is provided with an extension wing 23 for hand force application. It is convenient for the operator to rotate the end fin 222.

[0043] Of course, the above are only typical examples of the present application. In addition, the present application may have many other specific implementation methods. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present application.
