DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0018] Please refer to Figures 1-3A heat dissipation device includes an outdoor unit body 1 and a heat dissipation plate 9. An annular frame 8 is fixedly installed around the periphery of the heat dissipation plate 9. A fixing seat 2 is fixedly installed at the exhaust end of the outdoor unit body 1. Positioning seats 3 are fixedly installed on both sides of the fixing seat 2. Positioning seats 3 have positioning grooves 6, and the inner wall of the positioning grooves 6 has slots 7. Positioning blocks 11 are fixedly installed on both sides of the annular frame 8. Each positioning block 11 has multiple cavities 14 inside. Springs 15 are installed inside each cavity 14. One end of each spring 15 is fixed inside the cavity 14, and the other end of each spring 15 has a locking block 13. The locking block 13 cooperates with the slots 7. The internal structure has a telescopic rod that passes through the spring 15. Through the cooperation of the locking block 13 and the locking groove 7, it can provide a limiting effect for the positioning block 11 inside the positioning groove 6, making the annular frame 8 and the heat sink 9 more securely installed. When the heat sink 9 needs to be cleaned, a pulling force is applied to the annular frame 8. When the pulling force is greater than the elastic force of the spring 15, the locking block 13 will compress the spring 15. During the compression process, the telescopic rod will retract, which can make the locking block 13 disengage from the locking groove 7, thereby allowing the positioning block 11 to disengage from the positioning groove 6, and then the annular frame 8 can be disassembled. This process does not require the removal of multiple screws, the disassembly process is simple, saves labor, and has high cleaning efficiency.

[0019] The lack of a positioning structure between the ring frame 8 and the fixed base 2 will affect the stability of the ring frame 8 after installation. The fixed base 2 is provided with multiple positioning holes 4, and multiple limiting blocks 12 are fixedly arranged on the periphery of the ring frame 8 and inserted into the positioning holes 4, thereby providing a positioning structure between the ring frame 8 and the fixed base 2 and improving the stability of the ring frame 8 after installation.

[0020] In this structure, a sealing ring 5 is fixedly installed on the fixed base 2. The sealing ring 5 is bonded to the fixed base 2. After the annular frame 8 is fixed, it will squeeze the sealing ring 5, which can improve the sealing performance at the joint between the annular frame 8 and the fixed base 2.

[0021] In this structure, the card block 13 is a trapezoidal structure.

[0022] The lack of stress points on the ring frame 8 makes it difficult to pick up. Handles 10 are fixedly installed on both sides of the ring frame 8.
