Technical Field

[0001] This utility model relates to the field of refrigeration and air conditioning technology, and in particular to a refrigeration and air conditioning heat exchange device that is easy to disassemble and assemble. Background Technology

[0002] Air conditioning heat exchangers are an important component of air conditioning systems, used to achieve the heat exchange process of air. Air conditioning systems transfer heat from indoors to outdoors through heat exchangers, thereby cooling the indoor air. In traditional air conditioning systems, heat exchangers typically consist of two parts: an evaporator and a condenser. These heat exchangers achieve indoor cooling through the circulation of refrigerant. When indoor air passes through the evaporator, the refrigerant absorbs heat from the air, making the indoor air cooler; while in the condenser, the refrigerant releases heat, making the outdoor air warmer. However, existing air conditioning heat exchangers are generally of a single, integrated structure, and the dustproof structure is mostly bolted to the outdoor unit. Disassembly and replacement are complex and inefficient, and it is not conducive to cleaning dust from the dustproof structure. Therefore, we propose a refrigeration and air conditioning heat exchange device that is easy to disassemble and assemble. Utility Model Content

[0022] like Figure 1-4 As shown, this utility model is a heat exchange device for refrigeration and air conditioning that is easy to assemble and disassemble. It includes a housing 1, inside which are a plurality of equidistantly arranged heat exchange fins 2. Heat exchange tubes 3 are inserted into the heat exchange fins 2. A fixing frame 4 is provided on one side of the housing 1, and a filter screen 5 is provided in the center of the fixing frame 4. When the heat exchange device is working, the filter screen 5 can filter the flowing air, preventing dust and other impurities from adhering to the heat exchange fins 2, thereby effectively ensuring the heat exchange effect of the heat exchange device. A connecting block 6 is provided on one side of the fixing frame 4, and a shaft 7 is provided in the center below the connecting block 6. A sleeve 8 matching the shaft 7 is provided on the housing 1. The shaft 7 is inserted into the sleeve 8, allowing the connecting block 6 to rotate around the sleeve 8 via the shaft 7, thereby causing the filter screen 5 to rotate as well. By adjusting the position of the filter screen 5, it becomes easier to clean. Two fixing blocks 9 are provided on the side of the housing 1 away from the sleeve 8. The fixing blocks 9 are fixedly connected to the locking block 10 on the side away from the housing 1. A connecting groove 11 matching the locking block 10 is provided on the fixing frame 4. Limiting grooves 12 are provided on both sides of the connecting groove 11. A spring 13 is provided at the bottom of the limiting groove 12. A limiting block 14 is provided on the side of the spring 13 near the connecting groove 11. When the locking block 10 is inserted into the connecting groove 11, the limiting block 14 moves to one side of the connecting groove 11 under the action of the spring 13. The limiting block 14 and the side of the locking block 10 near the fixing block 9 press against each other. Through the mutual cooperation between the limiting block 14 and the locking block 10, the locking block 10 can be stably fixed inside the connecting groove 11.

[0023] Both ends of the locking block 10 away from the fixing block 9 are provided with inclined surfaces. The inclined surfaces make it easier for the locking block 10 to push the limiting block 14 when it enters the connecting groove 11.

[0024] The limiting block 14 has inclined surfaces at both ends on the side away from the spring 13. When the locking block 10 is disengaged from the connecting groove 11, the limiting block 14 can move inside the limiting groove 12 under the push of the locking block 10.

[0025] The fixed frame 4 is provided with a groove 15 on the side away from the connecting block 6. The groove 15 makes it easier to open and close the fixed frame 4.

The upper end of the shell 1 is provided with a water inlet pipe 16 connected to the heat exchange tubes 3, and the lower end of the shell 1 is provided with a water outlet pipe 17 connected to the heat exchange tubes 3. Cooling water can enter the interior of the heat exchange tubes 3 through the water inlet pipe 16, and the cooling water after heat exchange can be discharged through the water outlet pipe 17.

[0027] The housing 1 is provided with mounting plates 18 on both sides, and mounting grooves 19 are provided on both sides of the mounting plates 18. The heat exchange device can be fixedly installed through the mounting grooves 19 on the mounting plates 18.

[0028] Specifically, in this utility model, when the heat exchange device is working, the filter screen 5 can filter the flowing airflow, preventing dust and other impurities from adhering to the heat exchange fins 2, thereby effectively ensuring the heat exchange effect of the heat exchange device. The shaft 7 is inserted into the sleeve 8, so that the connecting block 6 can rotate around the sleeve 8 through the shaft 7, thereby causing the filter screen 5 to rotate as well. By adjusting the position of the filter screen 5, it is easier to clean the filter screen 5. When the locking block 10 is inserted into the connecting groove 11, under the action of the spring 13, the limiting block 14 moves to one side of the connecting groove 11. The limiting block 14 and the locking block 10 press against each other on the side near the fixing block 9. Through the cooperation between the limiting block 14 and the locking block 10, the locking block 10 can be stably fixed inside the connecting groove 11, thereby allowing the fixing frame 4 to be stably installed on the housing 1. At the same time, the fixing frame 4 and the filter screen 5 are easy to disassemble, making it easier to replace and maintain the fixing frame 4 and the filter screen 5.
