Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Embodiment 1, refer to Figure 1-3 A heat dissipation structure of an electric forklift controller includes a chassis 1, a water tank 2 is installed on the top outer wall of the chassis 1, and a square heat dissipation bin 3 is arranged on the top outer wall of the water tank 2, a water cooling coil 4 is connected between the water inlet and the water outlet of the water tank 2, and a water pump 5 is installed on the outer wall of the water cooling coil 4, a mounting plate 6 is fixedly connected to the bottom outer wall of the square heat dissipation bin 3 by bolts, and fans 7 distributed at equal distances are installed on the bottom outer wall of the mounting plate 6, symmetrically distributed water bags 8 are arranged on the top of the square heat dissipation bin 3, and a water pipe 9 is connected between the water bag 8 and the water cooling coil 4, and a butt pipe 10 is connected between the two water bags 8.

[0024] In this embodiment, a heat dissipation method of a water-cooling plus air-cooling structure is adopted. The controller body 14 is first air-cooled by the air blown by the fan 7, and then water-cooled by two water bags 8 close to the surface of the controller body 14. On this basis, the fan 7 can also take away excess heat in the water-cooling coil 4. In this cyclic heat dissipation process, the heat dissipation effect of the controller body 14 is greatly improved.

[0025] Example 2, refer to Figure 3 , a heat dissipation structure of an electric forklift controller, wherein the outer walls of one side of two water bags 8 are connected with arm frames 11, and a spring 12 is connected between the two arm frames 11.

[0026] In this embodiment, the controller body 14 of the electric forklift can be pre-placed in the air duct opening 16. Under the action of the spring 12, the two water bags 8 can approach each other and squeeze the controller body 14. The controller body 14 can be limited while being water-cooled. In a limited installation environment, the difficulty of disassembly and assembly of the controller body 14 is greatly reduced.

[0027] Reference Figure 1 The water cooling coil 4 is coiled on the inner wall of the square heat dissipation bin 3 .

[0028] Reference Figure 3 A positioning sleeve 13 is welded on the top outer wall of the square heat dissipation chamber 3 , and the spring 12 is arranged inside the positioning sleeve 13 .

[0029] Reference Figure 2-4 A controller body 14 is arranged on the top of the square heat dissipation bin 3 , and heat dissipation plates 15 are welded to the outer wall at the bottom of the controller body 14 and are distributed at equal distances. An air duct opening 16 is opened on the outer wall at the top of the square heat dissipation bin 3 , and the heat dissipation plates 15 are arranged inside the air duct opening 16 .

[0030] Reference Figure 3 A symmetrically distributed slide 17 is welded to the top outer wall of the square heat dissipation bin 3 , and the water bag 8 is slidably connected to the inner wall of the slide 17 .

[0031] Reference Figure 1 A forklift power supply compartment 18 is installed at one end of the top outer wall of the square heat dissipation compartment 3 away from the controller body 14.

[0032] Reference Figure 2 The chassis 1 and the square heat dissipation bin 3 are fixedly connected with symmetrically distributed columns 19 by bolts.

[0033] Working principle: The controller body 14 of the electric forklift can be placed in the air duct opening 16 in advance. Under the action of the spring 12, the two water bags 8 can approach each other and squeeze the controller body 14 to fix the controller body 14. In the heat dissipation stage, the controller body 14 will first be cooled by the blowing of the fan 7, and the cold air will be blown into the air duct opening 16 to dissipate the heat of the heat sink 15 of the controller body 14. Then, under the operation of the water pump 5, the water in the water tank 2 will form two paths. One path is connected to the square heat dissipation bin 3 using the water cooling coil 4, and the other path flows into the two water bags 8 through the water pipe 9 to cool the surface of the controller body 14. On this basis, the fan 7 can also take away excess heat in the water cooling coil 4.
