[0002] Finned evaporators are key components in the field of refrigeration and heat exchange, and are widely used in cooling systems of household air conditioners, refrigerators, commercial cold storage, refrigerated trucks, industrial chillers, and industries such as chemical, food processing, and pharmaceutical.

[0003] A utility model patent with patent authorization announcement number CN216953620U discloses a finned evaporator, including a fixing component and a serpentine tube. The fixing component includes a fixing frame, a fin assembly, and a fixing bracket. The fixing frame is threadedly connected to the fixing bracket. The fin assembly includes cross-distributed heat dissipation fins and a heat conduction groove that cooperates with the serpentine tube. The side wall of the heat conduction groove is provided with a heat conduction plate that is fixedly connected to the heat dissipation fins. The heat conduction plate has a thermally conductive silicone grease layer on the side away from the heat dissipation fins, which can realize convenient disassembly and assembly, reduce production costs, and improve cleaning efficiency.

[0004] In the aforementioned prior art, the fixed frame and bracket are connected and fixed with bolts during the use of the evaporator. When internal structural maintenance is required, disassembling the fixed frame and bracket requires the use of other tools, which is time-consuming, labor-intensive, and inconvenient. Furthermore, the evaporator has a ventilation screen, which easily accumulates dust after use, and its disassembly is also inconvenient for cleaning and maintenance. Therefore, improvements are needed. Utility Model Content

A first spring is provided on the outer side of the magnetic rod, and a magnet is fixedly connected inside the fixed frame. This assembly mechanism facilitates the disassembly of the fixed frame and the mounting bracket.

[0008] Preferably, the connecting post has a slot inside, and a plug is slidably connected inside the slot. By designing the slot, the plug can slide inside the connecting post.

[0009] Preferably, one end of the first spring is fixedly connected to the push rod, and the other end of the first spring is fixedly connected to the fixed frame. By designing the first spring, its force can be applied to the push rod.

[0010] Preferably, the connecting mechanism includes a rotating shaft, which is rotatably sleeved inside the connecting plate. A knob is fixedly connected to the top of the rotating shaft and rotatably connected to the connecting plate. A rotating seat is fixedly connected to the bottom of the rotating shaft, and a fixed rod is fixedly connected inside the rotating seat. A second spring is provided on the outside of the fixed rod, and an arc-shaped block is slidably sleeved on the outside of the fixed rod. The arc-shaped block is slidably connected to the rotating seat and to the fixed frame. This connecting mechanism facilitates the disassembly of the connecting plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, through the design of a sliding connection between the connecting column and the fixed frame, can limit the horizontal direction of the fixed frame to prevent it from shaking. By inserting the plug into the connecting column, the fixed frame can be fixed, thereby limiting the vertical direction of the fixed frame. This achieves the purpose of combining the fixed frame and the fixed bracket. By pushing the push rod, the plug and the connecting column can be separated, making it convenient to disassemble the fixed frame and the fixed bracket for internal structure inspection and maintenance.

[0015] 2. This utility model utilizes a ventilation mesh to ventilate the interior of the evaporator. The ventilation mesh is fixed in place by connecting the connecting plate and the fixed frame. The connection between the connecting plate and the fixed frame is achieved by inserting the arc-shaped block and the arc-shaped groove. When the connecting plate needs to be removed, the arc-shaped block and the arc-shaped groove can be separated by turning the knob, making it easy to disassemble the connecting plate and facilitate cleaning and maintenance of the ventilation mesh, thus preventing excessive dust accumulation from affecting its use.

A magnet 86 is fixedly connected inside the fixed frame 5. The assembly mechanism 8 facilitates the separation of the fixed frame 5 and the fixed bracket 1.

[0024] Please see Figure 1 , Figure 2 , Figure 4 The connecting mechanism 9 includes a rotating shaft 91, which is rotatably sleeved inside the connecting plate 6. A knob 92 is fixedly connected to the top of the rotating shaft 91 and is rotatably connected to the connecting plate 6.

[0026] When it is necessary to disassemble the fixed frame 5, push the push rod 81 horizontally. The push rod 81 will drive the magnetic suction rod 84 to move horizontally, and the push rod 81 will squeeze the first spring 85.

[0027] When it is necessary to disassemble the connecting plate 6, simply turn the knob 92. The knob 92 drives the rotating shaft 91 to rotate, which in turn drives the rotating seat 93 to rotate. The rotating seat 93 drives the arc block 96 to rotate, and the arc block 96 slides along the arc surface of the arc groove 97. The arc block 96 is squeezed by the arc surface and slides horizontally into the rotating seat 93. The arc block 96 slides along the fixed rod 94 and squeezes the second spring 95, which can separate the arc block 96 from the arc groove 97. Then, move the connecting plate 6 up and remove the positioning block 10 from the fixed frame 5 to disassemble the connecting plate 6. This facilitates the cleaning and maintenance of the ventilation screen 7 and avoids excessive dust accumulation that may affect its use.
