Description

Technical Field

[0001] This utility model relates to the field of condenser technology, specifically to a heat exchange copper tube for condensers that is easy to assemble. Background Technology

[0002] Condensers play an indispensable role in refrigeration, HVAC, and numerous heat exchange systems, and their performance directly affects the operating efficiency and stability of the entire system. As a key component for achieving efficient heat exchange in condensers, the rationality and reliability of the connection method of the heat exchange copper tubes are crucial.

[0003] According to announcement number CN 214307622 U, the structure of a heat exchange copper tube for an air source water heater includes a copper tube body with a D-shaped cross-section. One side of the copper tube body is provided with a straight heat exchange surface, and the other side is provided with an arc-shaped surface. The interior of the copper tube body is provided with several baffles evenly distributed on the inner wall of the arc-shaped surface.

[0004] This device uses a D-shaped, flat heat exchange surface to contact the water tank, thereby increasing the contact area between the heat exchange copper tubes and the water tank, and thus improving heat exchange efficiency. Furthermore, several inclined baffles are installed inside the heat exchange copper tubes on the inner wall of the curved surface. When the fluid column composed of refrigerant flows inside the heat exchange copper tubes, the baffles obstruct and guide the refrigerant near the curved surface to the flat heat exchange surface, facilitating the heat exchange of the refrigerant near the curved surface and further improving the heat exchange efficiency of the heat exchange copper tubes. However, this device splices the copper tubes by welding, which has many drawbacks, including wasting a lot of time and low efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a heat exchange copper tube for condensers that is easy to assemble, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a heat exchange copper tube for a condenser that is easy to splice, comprising a first copper tube and a second copper tube, wherein a connecting mechanism is provided on the surface of the first copper tube and the second copper tube, and a limiting mechanism is provided on the surface of the connecting mechanism.

[0007] The connecting mechanism includes a first external threaded cylinder and a third external threaded cylinder. The first external threaded cylinder is inserted into the surface of a first copper tube, and the third external threaded cylinder is inserted into the surface of a second copper tube. A first rectangular groove is formed at the left end of the first external threaded cylinder. A first rubber pad is fixedly connected to the inner wall of the first external threaded cylinder near the left end. A first internal threaded cylinder is threadedly connected to the surface of the first external threaded cylinder. A second external threaded cylinder is fixedly connected to the right end of the first external threaded cylinder. A second rectangular groove is formed at the right end of the third external threaded cylinder. A second rubber pad is fixedly connected to the inner wall of the third external threaded cylinder near the right end. A second internal threaded cylinder is threadedly connected to the surface of the third external threaded cylinder. An annular groove is formed on the surface of the third external threaded cylinder near the left end. A rotating ring is rotatably connected in the annular groove. A third internal threaded cylinder is fixedly connected to the outer ring of the rotating ring.

[0008] Preferably, the diameters of the first copper tube and the second copper tube are equal, the inner diameters of the first external threaded cylinder and the second external threaded cylinder are both equal to the diameter of the first copper tube, and the diameter of the third external threaded cylinder is equal to the diameter of the second copper tube.

[0009] Preferably, the third internal threaded cylinder is threadedly connected to the second external threaded cylinder, and the thread direction of the first external threaded cylinder is opposite to that of the third external threaded cylinder.

[0010] Preferably, the limiting mechanism includes a first fixing ring and a second fixing ring. The first fixing ring is fixedly connected to the outer wall of the first external threaded cylinder, and the second fixing ring is fixedly connected to the outer wall of the second external threaded cylinder. A fixing plate is fixedly connected to the outer wall of the first fixing ring at equal intervals. A screw is provided on the left side of the fixing plate. A limiting plate is fixedly connected to the left end of the screw. A third rectangular groove is provided on the right side of the second fixing ring at equal intervals. A limiting ring is sleeved on the surface of the screw, and a nut is threadedly connected to the surface of the screw.

[0011] Preferably, the fixing plate has a hole on its left side, and the diameter of the hole is larger than the diameter of the screw. The screw passes through and is located in the hole on the left side of the fixing plate. The diameter of the limiting plate is larger than the diameter of the hole to prevent the screw from sliding out of the hole.

[0012] Preferably, the screw is located within the third rectangular groove.

[0013] Preferably, the inner diameter of the limiting ring is greater than the diameter of the screw, and the outer diameter of the limiting ring is greater than the width of the third rectangular groove.

[0014] Compared with the prior art, this utility model provides a heat exchange copper tube for condensers that is easy to splice, and has the following beneficial effects:

[0015] This easily assembled condenser uses heat exchange copper tubes. Through a connecting mechanism, the first internally threaded cylinder is first threadedly connected to the first externally threaded cylinder. Then, the first externally threaded cylinder is inserted into the surface of the first copper tube, with the right end of the second externally threaded cylinder close to the right end of the copper tube. Next, the first internally threaded cylinder is rotated in the opposite direction, moving it to the left and simultaneously pressing the left end of the first externally threaded cylinder. This causes the first rubber pad on the inner wall of the first externally threaded cylinder to press against the first copper tube, thereby fixing the first and second externally threaded cylinders to the surface of the first copper tube. Then, the second internally threaded cylinder is threadedly connected to the third externally threaded cylinder. After that... The third external threaded cylinder is inserted into the surface of the second copper tube, with its left end close to the left end of the second copper tube. Then, the second internal threaded cylinder is rotated in the opposite direction, moving to the right and squeezing the right end of the third external threaded cylinder. This squeezes the second rubber pad on the inner wall of the third external threaded cylinder, thus fixing the third external threaded cylinder to the surface of the second copper tube. Then, the third internal threaded cylinder is rotated to connect with the second external threaded cylinder, causing the second copper tube to move towards the first copper tube, thus splicing the first and second copper tubes. This splicing method is more convenient and efficient than traditional welding.

[0016] This easily assembled condenser uses heat exchange copper tubes. After the first and second copper tubes are assembled via a limiting mechanism, the screw is inserted into the hole on the left side of the fixing plate. At this time, the right end of the screw is inserted into the third rectangular groove. Then, the limiting ring is placed on the surface of the screw, so that the left side of the limiting ring is in contact with the right side of the second fixing ring. Then, the nut is used to connect to the screw, so that the left side of the limiting ring tightly abuts against the right side of the second fixing ring, thereby limiting the first and second internal threaded cylinders. Since the threads of the first and third external threaded cylinders are in the same direction, the first and third internal threaded cylinders fix the first and second copper tubes in opposite directions. At the same time, the first and second internal threaded cylinders rotate in opposite directions, thus limiting the first and second internal threaded cylinders. Attached Figure Description

[0027] This utility model provides the following technical solution: Example

The first external threaded cylinder 31 is inserted into the surface of the first copper tube 1, and the third external threaded cylinder 36 is inserted into the surface of the second copper tube 2. The left end of the first external threaded cylinder 31 has a first rectangular groove 32. The inner wall of the first external threaded cylinder 31 is fixedly connected to the left end with a first rubber pad 33. The surface of the first external threaded cylinder 31 is threadedly connected to a first internal threaded cylinder 34. The right end of the first external threaded cylinder 31 is fixedly connected to a second external threaded cylinder 35. The right end of the third external threaded cylinder 36 has a second rectangular groove 37. The inner wall of the third external threaded cylinder 36 is fixedly connected to the right end with a second rubber pad 38. The surface of the third external threaded cylinder 36 is threadedly connected to a second internal threaded cylinder 39. The surface of the third external threaded cylinder 36 is opened near the left end with an annular groove 311. A rotating ring 312 is rotatably connected in the annular groove 311. The outer ring of the rotating ring 312 is fixedly connected to a third internal threaded cylinder 313.

[0030] The diameters of the first copper tube 1 and the second copper tube 2 are equal. The inner diameters of the first external threaded cylinder 31 and the second external threaded cylinder 35 are both equal to the diameter of the first copper tube 1. The diameter of the third external threaded cylinder 36 is equal to the diameter of the second copper tube 2.

[0031] The third internal threaded cylinder 313 is threadedly connected to the second external threaded cylinder 35, and the thread direction of the first external threaded cylinder 31 is opposite to that of the third external threaded cylinder 36. Example

[0032] Please see Figure 6 Furthermore, based on Embodiment 1, a limiting mechanism 4 is obtained.

[0033] The limiting mechanism 4 includes a first fixing ring 41 and a second fixing ring 45. The first fixing ring 41 is fixedly connected to the outer wall of the first external threaded cylinder 31, and the second fixing ring 45 is fixedly connected to the outer wall of the second external threaded cylinder 35. A fixing plate 42 is fixedly connected to the outer wall of the first fixing ring 41 at equal intervals. A screw 43 is provided on the left side of the fixing plate 42. A limiting plate 44 is fixedly connected to the left end of the screw 43. A third rectangular groove 46 is provided on the right side of the second fixing ring 45 at equal intervals. A limiting ring 47 is sleeved on the surface of the screw 43, and a nut 48 is threadedly connected to the surface of the screw 43.

[0034] A hole is provided on the left side of the fixing plate 42, and the diameter of the hole is larger than the diameter of the screw 43. The screw 43 passes through and is located in the hole on the left side of the fixing plate 42. The diameter of the limiting plate 44 is larger than the diameter of the hole to prevent the screw 43 from sliding out of the hole.

[0035] The screw 43 is located in the third rectangular groove 46.

[0036] The inner diameter of the limiting ring 47 is larger than the diameter of the screw 43, and the outer diameter of the limiting ring 47 is larger than the width of the third rectangular groove 46.

[0037] In actual operation, when this device is used, the first internal threaded cylinder 34 is first threadedly connected to the first external threaded cylinder 31. Then, the first external threaded cylinder 31 is inserted into the surface of the first copper tube 1, so that the right end of the second external threaded cylinder 35 is close to the right end of the copper tube. Then, the first internal threaded cylinder 34 is rotated in the opposite direction, so that the first internal threaded cylinder 34 moves to the left, while pressing the left end of the first external threaded cylinder 31. This causes the first rubber pad 33 on the inner wall of the first external threaded cylinder 31 to press against the first copper tube 1, thereby fixing the first external threaded cylinder 31 and the second external threaded cylinder 35 to the surface of the first copper tube 1. Then, the second internal threaded cylinder 39 is threadedly connected to the third external threaded cylinder 36, and then the third external threaded cylinder 35 is threaded into the first copper tube 1. The threaded cylinder 36 is inserted into the surface of the second copper tube 2, so that the left end of the third external threaded cylinder 36 is close to the left end of the second copper tube 2. Then, the second internal threaded cylinder 39 is rotated in the opposite direction, so that the second internal threaded cylinder 39 moves to the right, thereby squeezing the right end of the third external threaded cylinder 36, and then squeezing the second rubber pad 38 on the inner wall of the third external threaded cylinder 36, thereby fixing the third external threaded cylinder 36 to the surface of the second copper tube 2. Then, the third internal threaded cylinder 313 is rotated, so that the third internal threaded cylinder 313 and the second external threaded cylinder 35 are threadedly connected, thereby moving the second copper tube 2 towards the first copper tube 1, thereby splicing the first copper tube 1 and the second copper tube 2. This splicing method is more convenient and efficient than traditional welding.

[0038] After the first copper tube 1 and the second copper tube 2 are spliced ​​together, the screw 43 is inserted into the hole on the left side of the fixing plate 42. At this time, the right end of the screw 43 is inserted into the third rectangular groove 46. Then, the limiting ring 47 is placed on the surface of the screw 43, so that the left side of the limiting ring 47 is in contact with the right side of the second fixing ring 45. Then, the nut 48 is used to connect with the screw 43, so that the left side of the limiting ring 47 tightly abuts against the right side of the second fixing ring 45, thereby limiting the first internal threaded cylinder 34 and the second internal threaded cylinder 39. Since the threads of the first external threaded cylinder 31 and the third external threaded cylinder 36 are in the same direction, the first internal threaded cylinder 34 and the third internal threaded cylinder 313 are fixed in opposite directions to the first copper tube 1 and the second copper tube 2, and the first internal threaded cylinder 34 and the second internal threaded cylinder rotate in opposite directions. Therefore, the first internal threaded cylinder 34 and the second internal threaded cylinder 39 can be limited.
