[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figs. 1-3 In this embodiment of the present invention, a condenser tube with a microchannel structure includes a condenser tube outer layer 1, an air inlet 2 and an air outlet 3 fixed on the outer wall of the condenser tube outer layer 1, the air inlet 2 and the air outlet 3 being obliquely symmetrically distributed on the outer wall of the condenser tube outer layer 1, and a limiting mechanism 4 disposed on the condenser tube outer layer 1.
[0029] The limiting mechanism 4 includes a guide unit and a limiting unit;
[0030] The guiding unit is used to guide the flow of vapor and liquid entering the interior of the outer layer 1 of the condenser tube;
[0031] The limiting unit is used to provide limits for the installation of the guide unit;
[0032] The guiding unit includes a fixing ring 401 and a liquid guiding tube 402;
[0033] The retaining ring 401 is disposed on the inner side of both ends of the outer layer 1 of the condenser tube, and the retaining ring 401 is used to provide installation positioning for the liquid guide tube 402;
[0034] The liquid guide tube 402 is distributed inside the outer layer 1 of the condenser tube and passes through the two fixing rings 401 to both ends of the outer layer 1 of the condenser tube. The liquid guide tube 402 is used to guide the movement of vapor liquid at both ends of the outer layer 1 of the condenser tube.
[0035] The limiting unit includes a rotating ring 403, a guide groove 404, a limiting block 405, and a guide rod 406;
[0036] The rotating ring 403 is rotatably sleeved on the outer wall of the end of the outer layer 1 of the condenser tube. The rotating ring 403 is used to synchronously drive the guide groove 404 to rotate circumferentially.
[0037] Guide grooves 404 are formed on the outer walls of both ends of the rotating ring 403. Guide grooves 404 are used to provide vertical thrust to guide rod 406.
[0038] The limiting block 405 is vertically slidably installed inside the outer layer 1 of the condenser tube and extends to both sides of the fixing ring 401. The limiting block 405 is used to limit the axial movement of the fixing ring 401.
[0039] The guide rod 406 is fixed to the outer wall of the limiting block 405 and extends to the inner side of the guide groove 404. The guide rod 406 is used to synchronously drive the limiting block 405 to move vertically.
[0040] In this embodiment: With this structure, when it is necessary to clean the liquid guide tube 402, the rotating ring 403 is given rotational force. The rotating ring 403 synchronously drives the guide groove 404 to rotate circumferentially. The rotation of the inclined guide groove 404 will give the inner guide rod 406 a squeezing force. Since the movement trajectory of the limiting block 405 is vertical, when the guide rod 406 is squeezed by the inclined guide groove 404, the guide rod 406 will pull the limiting block 405 to move vertically along the inner sliding groove of the outer layer 1 of the condenser tube and enter the sliding groove. It will no longer move the two sides of the fixing ring 401. At this time, the fixing ring 401 can be pushed to remove the fixing ring 401 from the inside of the outer layer 1 of the condenser tube. The moving fixing ring 401 synchronously drives the liquid guide tube 402 to move out, which facilitates the simultaneous removal of multiple liquid guide tubes 402 for cleaning, further improving work efficiency.
[0041] Please refer to this carefully. Figs. 1-3 One end of the outer layer 1 of the condenser tube is made of metal, and the other end and the middle part are made of glass. The inner side of the port of the outer layer 1 of the condenser tube is formed with a sliding groove for the vertical movement of the limiting block 405. The outer wall of the guide groove 404 is inclined. The inner side of the guide groove 404 matches the outer wall of the guide rod 406. There are multiple limiting blocks 405. The multiple limiting blocks 405 are in pairs. A pair of limiting blocks 405 are symmetrically distributed on both sides of the fixing ring 401. There are two fixing rings 401. The two fixing rings 401 are located at the two ends of the outer layer 1 of the condenser tube.
[0042] In this embodiment: With this structure, after the fixing ring 401 is inserted into the outer layer 1 of the condenser tube, the movement of the fixing ring 401 can be limited by rotating the rotating ring 403, which will cause the limiting block 405 to fall from the inside of the outer layer 1 of the condenser tube. Multiple limiting blocks 405 move out simultaneously and are stuck in the upper and lower positions of the fixing ring 401. It should be noted that the outer wall of the fixing ring 401 is made of rubber. The rubber fixing ring 401 is used to provide a seal at the connection with the outer layer 1 of the condenser tube, and the limiting block 405 makes frictional contact with the outer wall of the fixing ring 401, which can prevent the rotating ring 403 from rotating on its own and improve the stability of the rotating ring 403.
[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
