Description

Technical Field

[0001] This utility model relates to the field of condenser technology, and in particular to a combined double-layer condenser. Background Technology

[0002] A condenser is a component of a refrigeration system and a type of heat exchanger. It can convert gas or vapor into liquid and transfer heat from the tubes to the air near the tubes in a very fast manner.

[0003] When a double-layer condenser is in operation, the refrigerant enters from the refrigerant inlet on the side of the upper tube of the double-layer parallel left manifold assembly, flows through the upper flat tube, enters the lower tube through the flow channel hole between the upper and lower tubes of the double-layer parallel right manifold assembly, and then flows back to the refrigerant outlet on the side of the lower tube of the double-layer parallel left manifold assembly through the lower flat tube. However, double-layer condensers are usually integrally welded. If a single layer of the condenser fails later, it is impossible to repair or replace the single layer. In case of failure, the entire double-layer condenser must be replaced, which results in high maintenance costs.

[0004] Therefore, we propose a combined double-layer condenser. Utility Model Content

[0005] The present invention aims to solve the technical problems existing in the prior art and provide a combined double-layer condenser.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a combined double-layer condenser, including a support frame, wherein there are two sets of supports. The upper support frame has an upper connecting pipe fixedly installed at both ends, and the lower support frame has a lower connecting pipe fixedly installed at both ends. A connecting pipe is provided between the upper and lower connecting pipes. Guide pipes are fixedly installed at the connection points of the upper and lower connecting pipes and the connecting pipes. The two ends of the connecting pipes are connected and fixed to the corresponding guide pipes by flanges and bolts. An alignment component is provided between the upper and lower sets of supports, and a fixing component is provided between the two sets of supports.

[0007] The fixing component includes a positioning block, which is fixedly installed on the upper bracket, and a limit block is fixedly installed on the lower bracket. An insertion block is fixedly installed at the bottom of the positioning block, and anti-detachment blocks are fixedly installed on both sides of the insertion block. Two abutment blocks are symmetrically slidably installed inside the limit block, and a synchronous drive component is provided on the limit block.

[0008] The synchronous drive assembly includes a connecting block, which is fixedly installed on both sides of the abutment block. The outer wall of the limiting block is provided with a synchronous shaft, a spring, a lifting block, and a synchronous ring.

[0009] Preferably, a refrigerant inlet pipe is fixedly installed on one of the upper connecting pipes, and the refrigerant inlet pipe is connected to the interior of the upper connecting pipe; a refrigerant outlet pipe is fixedly installed on one of the lower connecting pipes, and the refrigerant outlet pipe is connected to the interior of the lower connecting pipe; fins are uniformly fixedly installed on the support; flat tubes are uniformly fixedly installed on the support, and the flat tubes are interconnected with the interiors of the corresponding upper and lower connecting pipes.

[0010] Preferably, the alignment component includes an alignment block, which is fixedly installed on one side of the upper and lower connecting pipes that are close to each other. The alignment blocks on the upper and lower connecting pipes can fit together. An anti-deviation block is fixedly installed on the upper alignment block, and an insertion hole adapted to the anti-deviation block is opened on the lower alignment block.

[0011] Preferably, the connecting block and the limiting block are slidably connected, the synchronous shaft is rotatably mounted on the connecting block, two springs are fixedly mounted on the limiting block, two lifting blocks are slidably mounted on the limiting block, and the synchronous ring is slidably mounted on the limiting block.

[0012] Preferably, the lifting block is fixedly connected to one end of the spring, the lifting block is rotatably connected to two corresponding synchronous shafts, and the synchronous ring is fixedly connected to the lifting block.

[0013] Preferably, a short shaft is fixedly installed on the limiting block at the position corresponding to the spring, the short shaft is sleeved with the spring, the lifting block is sleeved with the short shaft, and the synchronous drive assembly also includes an outer cover, with two outer covers fixedly installed on the limiting block.

[0014] This utility model provides a combined double-layer condenser, which has the following improvements and advantages compared with the prior art: By setting two sets of supports, when assembling the two sets of supports, the positioning block is inserted into the limiting block for pre-positioning. During the inward pushing of the positioning block in the limiting block, the abutment block is pushed open to both sides by the connecting block, synchronous shaft, spring, and lifting block. When the positioning block is pushed in place, the abutment block closes to the middle position under the action of the connecting block, synchronous shaft, spring, and lifting block. After closing, the positioning block and the limiting block are limited and fixed by the cooperation of the anti-detachment block and the abutment block. After the support assembly is completed, when it is necessary to disassemble and replace the upper and lower parts of the condenser separately, the positioning block and the limiting block are separated by pushing the synchronous ring in conjunction with the action of the spring, lifting block, synchronous shaft, connecting block, and abutment block. After separation, the connecting pipe and the guide pipe can be disconnected, and the upper and lower parts of the condenser can be disassembled for individual replacement of the parts that need to be replaced, saving maintenance costs.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] A combined double-layer condenser, such as Figure 1 - Figure 6 As shown, the system includes a bracket 1, which has two sets. The upper bracket 1 has upper connecting pipes 2 fixedly installed at both ends. The upper connecting pipes 2 are hollow, and one of them has a refrigerant inlet pipe 6 fixedly installed, communicating with the interior of the upper connecting pipe 2. The lower bracket 1 has lower connecting pipes 3 fixedly installed at both ends. The lower connecting pipes 3 are hollow, and one of them has a refrigerant outlet pipe 7 fixedly installed, communicating with the interior of the lower connecting pipe 3. Fins 4 are evenly fixedly installed on the bracket 1. Flat tubes 5 are evenly fixedly installed on the bracket 1, communicating with the interiors of the corresponding upper connecting pipe 2 and lower connecting pipe 3. A connecting pipe 8, which is hollow, is provided between the upper connecting pipe 2 and the lower connecting pipe 3. Guide pipes 12 are fixedly installed at the connection points of the upper connecting pipe 2 and the lower connecting pipe 3 with the connecting pipe 8. The two ends of the connecting pipe 8 are connected to the corresponding guide pipes 12 by means of a method. The flanges and bolts are used to connect and fix each other. An alignment component is set between the upper and lower brackets 1. The alignment component can assist in positioning when assembling the two brackets 1. A fixing component is set between the two brackets 1 to limit and fix the two brackets 1. With the fixing component, when assembling the upper and lower brackets 1, the alignment component is used to align the two brackets 1. After alignment, the fixing component limits and fixes the two brackets 1. After the two brackets 1 are assembled and fixed, the two ends of the connecting pipe 8 are connected to the corresponding guide pipe 12 using flanges and bolts. After the whole assembly is completed, the condenser is assembled. After assembly, the condenser can be used to condense the gaseous condensate into liquid condensate. The condenser is assembled in two parts, upper and lower. When a part of the upper and lower parts needs to be replaced, the condenser can be disassembled and the part to be replaced can be replaced separately without replacing the whole thing, saving maintenance costs.

[0026] Furthermore, the alignment component includes an alignment block 9, which is fixedly installed on the upper connecting pipe 2 and the lower connecting pipe 3 on their adjacent sides. The alignment blocks 9 on the upper connecting pipe 2 and the lower connecting pipe 3 can fit together. An anti-deviation block 13 is fixedly installed on the upper alignment block 9, and an insertion hole adapted to the anti-deviation block 13 is opened on the lower alignment block 9. When assembling the two sets of brackets 1, the anti-deviation block 13 on the upper alignment block 9 can be inserted into the insertion hole on the lower alignment block 9 to quickly position the brackets 1 during assembly. By providing the alignment component, when assembling the two sets of brackets 1, the anti-deviation block 13 on the upper alignment block 9 can be inserted into the insertion hole on the lower alignment block 9 to quickly position the brackets 1 during assembly.

[0027] Furthermore, the fixing component includes a positioning block 10, which is fixedly mounted on the upper bracket 1. A limit block 11 is fixedly mounted on the lower bracket 1. An insertion block 15 is fixedly mounted on the bottom of the positioning block 10, and the insertion block 15 can be inserted into the interior of the limit block 11. Anti-detachment blocks 16 are fixedly mounted on both sides of the insertion block 15. Two abutments 17 are symmetrically slidably mounted inside the limit block 11. A synchronous drive component is provided on the limit block 11, which can cooperate to realize the locking operation between the insertion block 15, the anti-detachment blocks 16, and the abutments 17. With a fixing component, when assembling the two sets of brackets 1, the positioning block 10 is inserted into the limiting block 11 for pre-positioning. After the positioning block 10 and the limiting block 11 are positioned, the positioning block 10 and the limiting block 11 can be locked by the cooperation of the anti-detachment block 16, the stop block 17 and the synchronous drive component. After locking, the assembly of bracket 1 is completed. When it is necessary to replace the upper and lower parts of the condenser separately, the positioning block 10 and the limiting block 11 can be unlocked by the synchronous drive component to complete the disassembly. After disassembly, it can be replaced separately, saving maintenance costs.

[0028] Furthermore, the synchronous drive assembly includes a connecting block 18, which is fixedly installed on both sides of the abutment block 17. The connecting block 18 is slidably connected to the limiting block 11. A synchronous shaft 19 is rotatably installed on the connecting block 18 and is disposed on the outer wall of the limiting block 11. Two springs 20 are fixedly installed on the limiting block 11. A short shaft is fixedly installed on the limiting block 11 at the position corresponding to the springs 20 and is sleeved with the springs 20. Two lifting blocks 21 are slidably installed on the limiting block 11. The lifting blocks 21 are fixedly connected to one end of the springs 20 and are sleeved with the short shafts. The lifting blocks 21 are rotatably connected to the two corresponding synchronous shafts 19. A synchronous ring 22 is slidably installed on the limiting block 11 and is fixedly connected to the lifting blocks 21. Two outer covers 14 are fixedly installed on the limiting block 11. By providing the synchronous drive assembly, when assembling the two sets of brackets 1, the positioning block 10 is inserted into the limiting block 11. During the pre-positioning process, as the positioning block 10 is pushed inward within the limiting block 11, the abutment block 17 is pushed open to both sides by the connecting block 18, synchronous shaft 19, spring 20, and lifting block 21. After the positioning block 10 is pushed inward to its position, the abutment block 17 closes towards the center under the action of the connecting block 18, synchronous shaft 19, spring 20, and lifting block 21. After closing, the positioning block 10 and the limiting block 11 are fixed in place by the cooperation of the anti-detachment block 16 and the abutment block 17. The bracket 1 is then assembled. When it is necessary to disassemble and replace the upper and lower parts of the condenser separately, the positioning block 10 and the limiting block 11 are separated by pushing the synchronous ring 22 in conjunction with the action of the spring 20, lifting block 21, synchronous shaft 19, connecting block 18, and abutment block 17. After separation, the connecting pipe 8 and the guide pipe 12 can be disconnected to disassemble the upper and lower parts of the condenser and replace the parts that need to be replaced separately, thus saving maintenance costs.

[0029] The working principle of this utility model is as follows: Before the condenser is put into use, the upper and lower parts are assembled. During assembly, the alignment blocks 9 in the upper and lower parts are aligned with each other. The anti-deviation block 13 on the upper side is inserted into the insertion hole on the lower alignment block 9 for pre-positioning. At the same time, the positioning block 10 is inserted into the limiting block 11 and pushed inward.

[0030] During the process of the positioning block 10 being pushed inward in the limiting block 11, the insertion block 15 and the anti-detachment block 16 contact the abutment block 17 and press the abutment block 17 to both sides. After being pressed, the abutment block 17 moves to both sides and opens up. When the positioning block 10 is pushed inward, the anti-detachment block 16 moves to the lower side of the abutment block 17, the spring 20 rebounds and drives the lifting block 21 to slide downward. When the lifting block 21 moves downward, it drives the synchronous shaft rod 19 and the connecting block 18 to move closer to the middle position. The abutment blocks 17 on both sides move closer to the middle position to reset and limit the anti-detachment block 16. The connecting pipe 8 and the corresponding guide pipe 12 are aligned and fixed using flanges and bolts. At this time, the upper and lower brackets 1 are assembled into a complete condenser and put into use.

[0031] When the upper and lower layers of the condenser need to be repaired or replaced separately, disconnect the connecting pipe 8 from the guide pipe 12, push the synchronous ring 22 upward, and the synchronous ring 22 drives the lifting block 21 to move upward. When the lifting block 21 moves upward, it spreads the synchronous shaft rods 19 on both sides to the sides. When the synchronous shaft rods 19 are spread open, they drive the two abutment blocks 17 to slide open to the sides. At this time, pull the upper and lower brackets 1 to remove them. After the two brackets 1 are removed, the part that needs to be repaired or replaced separately can be processed.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
