The embodiment of the present invention symmetrically provides slots 10 on the outer surfaces of the side walls on opposite sides of the radiator 1, and the clip 3 is formed by fastening two clips 30 in a semi-enclosed structure, which occupies a smaller volume and is convenient for transportation. In addition, during the specific assembly, the free arms 303 of the two clips 30 are respectively inserted into the above-mentioned slot 10 from different ends of the above-mentioned slot 10 on opposite sides of the above-mentioned radiator 1 toward the openings 10a, 10b, so that the free arms 303 of the clip 30 are elastically pressed against the groove side walls 10c, 10c of the above-mentioned slot 10 located close to the bottom of the above-mentioned radiator, and the elastic snap-in portions 307 at the ends of the free arms 303 of the two clips 30 in the same-side slot 10 are matched and snap-fitted with each other to achieve the connection and positioning of the free arms 303 of the two clips 30, and disassembly and assembly are very convenient. In an optional embodiment of the present invention, as shown in Figures 3 to 5 , the elastic engaging portions 307 at the ends of the free arms 303 of the two clips 30 are offset relative to each other in the width direction of the free arms 303. In this embodiment, the elastic engaging portions 307 at the ends of the free arms 303 of the two clips 30 are offset relative to each other in the width direction of the free arms 303. When the two clips 30 are connected, the free arms 303 of the two clips 30 can laterally shield the engaging portion of the elastic engaging portions 307, thereby protecting the engaging portion. In yet another alternative embodiment of the present invention, as shown in FIG5 , the thickness of the cleat 30 matches the width of the slot 10, and the upper and lower sidewalls of the slot 10 abut against the upper and lower surfaces of the cleat 30, positioning the cleat 30 in the thickness direction of the cleat 30. In this embodiment, by matching the thickness of the cleat 30 to the width of the slot 10, the slot 10 is utilized to achieve positioning of the cleat 30 in the thickness direction. In another alternative embodiment of the present invention, as shown in FIG3 , the elastic engaging portions 307 at the ends of the two free arms 303 of one clip 30 are symmetrically arranged slots, while the elastic engaging portions 307 at the ends of the two free arms 303 of the other clip 30 are barbs.

The corresponding engagement portions 307a of the barbs that engage the slots are arc-shaped protrusions, which facilitate the engagement and removal of the barbs 307a from the slots, facilitating assembly. Furthermore, the clips 30 have the same structure, making manufacturing easier. In yet another alternative embodiment of the present invention, as shown in FIG4 , the elastic engaging portions 307 at the ends of the two free arms 303 of each clip 30 are respectively formed into a slot and a barb. Each clip 30 is secured by the barb engaging with the corresponding slot on the other clip 30. The corresponding barb engaging portion of the barb that engages within the slot is a circular arc-shaped protrusion. In this embodiment, the two free arms 303 of the two clips 30 are respectively provided with a slot and a barb. Similarly, the slot and the barb engage with each other to effectively achieve the snap-fit ​​and positioning of the free arms 303 of the two clips 30.
