[0024] It should be noted that: when clamping the radiator core, the lower plate 3 is abutted against the lower plate surface of the radiator core, and then the U-shaped rod 6 is pulled up to make the U-shaped rod 6 stretch the high-temperature spring 5, until the upper plate 7 is higher than the upper plate surface of the radiator core, and the upper plate 7 is aligned with the lower plate 3. Then, the U-shaped rod 6 is released. At this time, under the action of the high-temperature spring 5, the upper plate 7 firmly clamps the upper plate surface of the radiator core, and the radiator core can be clamped by tightening the threaded fixing rod 9;
