[0018] The following further details the specific embodiments of the fluid radiator of the present utility model in conjunction with the drawings.

[0019] As Figures 1 - 3As shown in the figure, the fluid radiator of this embodiment mainly consists of a heat exchanger 1, a fan 2, a fan mounting bracket 3 and an elastic snap spring 4. The fan mounting bracket 3 has a concave counterbore 30 inside. The fan 2 is embedded in the concave counterbore 30. The front of the fan mounting bracket 3 is provided with ventilation holes 33. Positioning grooves 10 are opened at the upper and lower ends of the heat exchanger 1. Locking parts 31 are provided at the upper and lower ends of the fan mounting bracket 3. The middle part of the elastic snap spring 4 is a fixing part 40, and the two free ends have clamping parts 41. Between the fixing part 40 and the clamping parts 41 is an elastic part 42. There are two elastic snap springs 4, which are respectively located at the upper and lower ends of the fan mounting bracket 3. Its fixing part 40 is embedded in the positioning groove 10 of the heat exchanger 1, and the clamping parts 41 cooperate with the locking parts 31 of the fan mounting bracket 3 to fix the fan mounting bracket 3 on the heat exchanger 1 through the elastic part 42. In order to prevent the elastic snap spring 4 from slipping off, it is preferably to design the positioning groove 10 with a width of the groove bottom greater than that of the groove top. In order to reduce the load-bearing requirements of the spring snap spring, limit blocks 32 can also be provided at the upper and lower ends of the fan mounting bracket 3. The limit blocks 32 are clamped at the upper and lower ends of the heat exchanger 1, so that the limit blocks 32 can play a greater role in assembly load-bearing.

[0020] In order to improve the assembly stability, it is preferably to design the locking parts 31 provided at the upper and lower ends of the fan mounting bracket 3 as locking holes extending towards the heat exchanger 1, and design the clamping parts 41 of the elastic snap spring 4 as locking posts facing the heat exchanger 1. The locking posts are located in the locking holes. Usually, the elastic snap spring 4 is made of spring steel, and the elastic part 42 of the elastic snap spring 4 can be designed as a V-shaped bending part.

[0021] For the fluid radiator of the present invention, the heat exchanger 1 preferably adopts a heat exchanger 1 with a tube-fin structure, including fluid straight pipes 11, fins 12, and connecting bent pipes 13. The fluid straight pipes 11 are channels for fluid to pass through, and are arranged between the parallel fins 12. The ends of the fluid straight pipes 11 are connected by the connecting bent pipes 13. The fins 12 are air-cooled radiating fins, and the high-temperature fluid in the fluid straight pipes 11 is dissipated by the fan 2. In order to facilitate the fixing of the water pump 5 and improve the overall structural compactness, a mounting member 6 for fixing the fluid pump 5 is also provided on the fan mounting bracket 3. For convenient and quick installation, the connecting bent pipe 13 is preferably made of a corrugated silicone pipe. The two ends are sleeved on the fluid straight pipes 11, and the middle is a corrugated structure 130 to avoid blocking the middle fluid channel after bending.

[0022] Preferably, the mounting member 6 on the fan mounting bracket 3 includes a first mounting member 60 integrally injection-molded with the fan mounting bracket 3 and a movable member 61 cooperating with the first mounting member 60. The movable member 61 is fixed to the first mounting member 60 by screws to fix the fluid pump 5.
