Description

Technical Field

[0001] This utility model relates to the field of surface cooler technology, and in particular to a surface cooler for fan coil units. Background Technology

[0002] In modern building HVAC systems, fan coil units, as terminal cooling and heating devices, rely on their core component, the surface cooler, for crucial heat exchange. The surface cooler exchanges heat with the air through circulating chilled or hot water, achieving multiple objectives such as indoor temperature regulation, humidity control, and air purification. A highly efficient and stable surface cooler not only improves the energy efficiency ratio of the fan coil unit and reduces building energy consumption, but also minimizes problems such as condensate leakage and excessive air resistance, ensuring indoor air quality and comfort. Furthermore, the easy-to-disassemble and maintain structure of the surface cooler significantly shortens equipment maintenance time, reduces operating costs, and prevents prolonged downtime of the air conditioning system due to component failure, which is especially important for places with extremely high environmental comfort requirements, such as hotels and office buildings.

[0003] Traditional fan coil unit surface coolers mostly adopt an integral welded or bolted structure. Welded surface coolers fix the heat exchange copper tubes to the aluminum fins by welding, and then weld the various parts of the shell into shape. Bolted surface coolers connect the shell, heat exchange module and other components with multiple bolts and nuts.

[0004] However, existing surface coolers generally suffer from cumbersome and time-consuming disassembly and assembly processes, resulting in low equipment maintenance efficiency and long fault repair cycles. In actual operation and maintenance, if the internal heat exchange tubes or fins of traditional welded surface coolers need to be replaced, it often requires professional personnel to use cutting and welding equipment, and a single repair can take several hours, which seriously affects the normal use of the site. Although bolt-fastened surface coolers can be disassembled, a single device usually requires the disassembly and assembly of multiple bolts, which is complicated and prone to secondary faults such as water leakage and air leakage due to bolt corrosion and poor sealing. Therefore, a surface cooler for fan coil units is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a surface cooler for fan coil units, aiming to improve the problems of cumbersome and time-consuming disassembly and assembly processes in the prior art, which lead to low equipment maintenance efficiency and long fault repair cycles.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A surface cooler for a fan coil unit includes a housing 1 and a housing 2, wherein mounting members are provided on the side walls of the housing 1 and the housing 2, a circulation assembly is provided inside the mounting members, and a connecting assembly is provided between the housing 1 and the housing 2.

[0008] The connecting assembly includes a connecting column and a hollow column.

The sliding plate is slidably connected inside the sliding groove. A telescopic column is provided between the sliding plate and the connecting column. A locking block is fixedly connected to one side of the sliding plate. A spring is sleeved on the outside of the telescopic column. The two ends of the spring are respectively connected to the sliding plate and the connecting column. A locking groove is formed inside the hollow column. The locking block engages with the locking groove.

[0009] As a further description of the above technical solution:

[0010] The circulation assembly includes a pipe that passes through the interior of the mounting component and through the interiors of housing one and housing two.

[0021] As a further description of the above technical solution:

[0022] The sliding sleeve has an internal groove, and the ball engages with the retaining ring.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, when assembling the surface cooler, the connecting column is inserted into the hollow column to compress the locking block, which drives the telescopic column and the sliding plate to move and compress the first spring. When the locking slot corresponds to the locking block, the first spring returns to its original position and pushes the locking block into the locking slot. This structure achieves the effect of quick assembly and disassembly of the surface cooler housing, solving the problems of cumbersome and time-consuming disassembly and assembly processes, resulting in low equipment maintenance efficiency and long fault repair cycles, thereby improving the convenience of surface cooler maintenance.

[0025] 2. In this utility model, when connecting to external pipelines, the connecting pipe is inserted into the connector, squeezing the ball bearing and pulling the sliding sleeve to compress the second spring. After insertion, the sliding sleeve is released, and the second spring returns to its original position, pushing the sliding sleeve to lock the ball bearing into the retaining ring for fixation. The sealing ring ensures a seal. This structure achieves rapid connection and disconnection between the surface cooler and external pipelines, solving the problems of complex operation, low connection efficiency, and difficulty in quickly adapting to different pipeline requirements in traditional pipeline connection methods, thereby improving the flexibility of the surface cooler.

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.

[0034] Reference Figures 1-3 The present invention provides an embodiment of a surface cooler for a fan coil unit, comprising a housing 1 and a housing 2, wherein mounting members 11 are provided on the side walls of the housing 1 and the housing 2, a circulation assembly is provided inside the mounting members 11, and a connecting assembly is provided between the housing 1 and the housing 2.

[0035] The connecting assembly includes a connecting post 3 and a hollow post 4. The connecting post 3 and the hollow post 4 are fixedly connected to the top of housing 1 and housing 2, respectively. The connecting post 3 is slidably connected inside the hollow post 4. A groove 10 is provided inside the connecting post 3. A sliding plate 6 is slidably connected inside the hollow post 4. The sliding plate 6 is slidably connected inside the groove 10. A telescopic post 7 is provided between the sliding plate 6 and the connecting post 3. A locking block 9 is fixedly connected to one side of the sliding plate 6. A spring 8 is sleeved on the outside of the telescopic post 7. The two ends of the spring 8 are connected to the sliding plate 6 and the connecting post 3, respectively. When the connecting post 3 is inserted into the hollow post 4, the locking block 9 is squeezed and drives the sliding plate 6 to slide along the groove 10, simultaneously compressing the spring 8 sleeved on the outside. A slot 5 is provided inside the hollow post 4. The locking block 9 engages with the slot 5. When the slot 5 on the connecting post 3 is aligned with the slot 5 inside the hollow post 4, the spring 8 resets and pushes the sliding plate 6, so that the locking block 9 is precisely engaged in the slot 5, forming a mechanical lock.

[0036] Reference Figure 1 , Figure 4 and Figure 5The circulation component includes a pipe 12, which passes through the mounting component 11 and the housing 1 and housing 2. Both the output and input ends of the pipe 12 are fixedly connected to a connector 13. A retaining ring 14 is fixedly connected to the outer wall of the connector 13. A connecting pipe 15 is slidably connected to the outer wall of the connector 13. A sliding sleeve 16 is slidably connected to the outer wall of the connecting pipe 15. A sealing ring 19 is provided inside the connecting pipe 15, and the connector 13 contacts the sealing ring 19. A retaining ring 17 is fixedly connected to the outer wall of the connecting pipe 15, and a ball bearing is slidably connected inside the connecting pipe 15. 20. A second spring 18 is fitted on the outer wall of the connecting pipe 15. The two ends of the second spring 18 are connected to the sliding sleeve 16 and the fixing ring 17 respectively. A slot 21 is opened inside the sliding sleeve 16. The ball 20 inside the connecting pipe 15 is squeezed by the connector 13, moves outward and retracts into the slot 21 of the sliding sleeve 16. The ball 20 engages with the retaining ring 14. When the connecting pipe 15 is inserted to the position of the retaining ring 14, the sliding sleeve 16 is released, the second spring 18 returns to its original position and pushes the sliding sleeve 16 forward, so that the ball 20 is engaged in the groove of the retaining ring 14, forming a mechanical lock, realizing the quick insertion and removal of the pipeline.

[0037] Working principle: When assembling the surface cooler, the connecting post 3 on the housing 1 is aligned with the hollow post 4 on the housing 2 and inserted. The connecting post 3 presses against the locking block 9, causing the locking block 9 to move the telescopic post 7 and the sliding plate 6, compressing the spring 8. When the slot 5 on the connecting post 3 corresponds to the locking block 9, the spring 8 returns to its original position and pushes the sliding plate 6 and the telescopic post 7, causing the locking block 9 to engage with the slot 5, thus completing the assembly of the surface cooler and achieving the effect of facilitating the disassembly and maintenance of the surface cooler.

[0038] When connecting to an external pipeline, insert the connecting pipe 15 into the connector 13. The connecting pipe 15 squeezes the ball 20 and simultaneously pulls the sliding sleeve 16, causing the ball 20 to retract into the sliding sleeve 16. At the same time, the sliding sleeve 16 compresses the second spring 18. When the connecting pipe 15 is inserted to the appropriate position, release the sliding sleeve 16. The second spring 18 returns to its original position and pushes the sliding sleeve 16, causing the ball 20 to be locked onto the retaining ring 14 on the outer wall of the connector 13, thus completing the fixation and realizing the connection between the connecting pipe 15 and the connector 13. The sealing ring 19 ensures the seal at the connection point. When disassembly and maintenance are required, the effect of quick connection to an external pipeline is achieved.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
