DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. The utility model is further described in combination with the drawings and embodiments:

[0023] like Figure 1-Figure 4 As shown, a water-cooled heat exchanger includes an outer box 1, which is the main structure of the heat exchanger and provides a stable external environment and protection. A support frame is provided in the outer box, and a plurality of serpentine heat exchange tubes 2 are supported on the support frame. The support frame enhances the overall structural strength of the heat exchanger and provides effective support for the internal heat exchange pipeline. The two ends of the serpentine heat exchange tube extend out of the outer box to form a liquid inlet pipe and a liquid outlet pipe, respectively, so that the coolant can flow in the heat exchange tube to complete the heat exchange process. The support frame includes two side plates 3, and multiple groups of clamping mechanisms 4 are provided between the two side plates. The side plates provide a stable installation foundation for the clamping mechanism. The setting of multiple groups of clamping mechanisms ensures that the serpentine heat exchange tube can be effectively fixed at all positions, thereby improving the overall stability and reliability. The upper clamping plate 47 and the lower clamping plate 48 of the clamping mechanism can be clamped on the outer wall of the serpentine heat exchange tube to achieve a fixed connection between the serpentine heat exchange tube and the outer box. This clamping method is simple and easy to use, and can quickly complete the installation and removal of the serpentine heat exchange tube, which is convenient for maintenance. At the same time, through the clamping action of the clamping mechanism, the fixed connection between the serpentine heat exchange tube and the outer box is achieved, ensuring the stability of the heat exchange process.

[0024] In at least one embodiment, the side plate is fixedly connected to the inner wall of the outer box body by bolts 31. This connection method is stable and reliable, convenient for assembly and disassembly, and can adapt to heat exchangers of different specifications and requirements.

[0025] The solution is refined, and the inner wall of the outer box body is provided with a fixing threaded hole that matches the bolt.

[0026] In at least one embodiment, the clamping mechanism includes an upper clamping plate 47, a lower clamping plate 48 and a diamond-shaped rotating block 44, and in cooperation therewith, a sliding groove 41 is provided on the side plate, and the upper clamping plate and the lower clamping plate are slidably matched in the sliding groove, and the sliding groove provides a guide and limit function for the movement of the clamping plate. A central threaded hole is provided in the middle of the sliding groove, and a rotating shaft 45 is installed in the central threaded hole, and a diamond-shaped rotating block is rotatably connected to the rotating shaft, and the diamond-shaped rotating block can be rotated so that the upper clamping plate and the lower clamping plate are against the outer surface of the serpentine heat exchange tube. The design of the diamond-shaped rotating block enables the upper clamping plate and the lower clamping plate to move synchronously, thereby achieving uniform clamping of the serpentine heat exchange tube.

[0027] Furthermore, an adjusting knob 46 is installed at the end of the rotating shaft, and the adjusting knob can limit the rotation of the diamond-shaped rotating block around the rotating shaft. The setting of the adjusting knob facilitates the precise control of the rotation angle of the diamond-shaped rotating block, thereby realizing the precise adjustment of the clamping force of the serpentine heat exchange tube.

[0028] In a refinement of the scheme, the end of the rotating shaft is provided with an external thread, and the adjusting knob can be threadedly connected to the external thread of the rotating shaft and abut against the surface of the diamond-shaped rotating block. This connection method not only ensures the stability of the adjusting knob but also facilitates its disassembly, assembly and maintenance.

[0029] Furthermore, an upper rubber slider 42 and a lower rubber slider 43 are slidably matched in the sliding groove, an upper clamping plate is fixedly connected to the upper rubber slider, and a lower clamping plate is fixedly connected to the lower rubber slider. This connection method ensures synchronous movement of the clamping plate and the rubber slider, and improves overall stability and reliability.

[0030] In detail, when the diamond-shaped rotating block can rotate so that the upper clamping plate and the lower clamping plate are against the outer surface of the serpentine heat exchange tube, the two ends of the diamond-shaped rotating block are respectively in contact with the upper rubber slider 42 and the lower rubber slider 43, and the upper rubber slider 42 and the lower rubber slider 43 are elastically deformed. This elastic deformation can increase the clamping force of the serpentine heat exchange tube and play a buffering role to reduce damage to the serpentine heat exchange tube.

[0031] Furthermore, the upper clamping plate 47 and the lower clamping plate have a plurality of supporting grooves 471 in a linear array that match the serpentine heat exchange tube. The arrangement of the supporting grooves can better support and position the serpentine heat exchange tube to prevent it from shaking or deflecting during use.

[0032] In at least one embodiment, Figure 4As shown, the upper rubber slider is provided with an upper extension plate 421, and the upper extension plate and the upper rubber slider form an upper clamping slot 422 for accommodating the upper clamping plate to be inserted; similarly, the lower rubber slider is provided with a lower extension plate, and the lower extension plate and the lower rubber slider form a lower clamping slot for accommodating the lower clamping plate to be inserted. This design of the clamping slot makes the installation of the clamping plate more stable and not easy to fall off, and also facilitates the replacement and maintenance of the clamping plate.

[0033] The steps to install the device are as follows:

[0034] 1. Fix the side panels to the inner wall of the outer box with bolts, matching them with the fixing threaded holes on the inner wall of the outer box to complete the installation of the side panels.

[0035] 2. Slide the upper rubber slider and the lower rubber slider in the sliding groove, fix the upper clamping plate on the upper rubber slider, fix the lower clamping plate on the lower rubber slider, and install the diamond-shaped rotating block in the center threaded hole of the sliding groove through the rotating shaft.

[0036] 3. Thread the adjusting knob onto the external thread of the rotating shaft and place it against the surface of the diamond-shaped rotating block to limit the rotation of the diamond-shaped rotating block around the rotating shaft.

[0037] 5. Extend the two ends of the serpentine heat exchange tube out of the outer box to form a liquid inlet pipe and a liquid outlet pipe, and place the serpentine heat exchange tube in the clamping mechanism. Turn the adjusting knob to rotate the diamond-shaped rotating block, so that the upper clamping plate and the lower clamping plate are against the outer surface of the serpentine heat exchange tube.

[0038] During use, liquid enters the serpentine heat exchange tube through the liquid inlet pipe, and flows out through the liquid outlet pipe after heat exchange, thus realizing the heat exchange process. The serpentine heat exchange tube is fixedly connected to the outer box through the clamping mechanism, which ensures the stability during the heat exchange process. When the serpentine heat exchange tube needs to be replaced or repaired, just turn the adjustment knob to make the diamond-shaped rotating block rotate in the opposite direction, and the upper clamping plate and the lower clamping plate can release the clamping of the serpentine heat exchange tube to remove the serpentine heat exchange tube.

[0039] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions in the specification are only to illustrate the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the protection required by the utility model. The scope of protection required by the utility model is defined by the attached claims and their equivalents.
