[0036] The names of the messages or information exchanged between the multiple devices in this embodiment of the invention are for illustrative purposes only and are not intended to limit the scope of these messages or information.

[0037] See Figure 1 , Figure 2 , Figure 3 and Figure 4 The present invention provides a heat dissipation arrangement device for excavators, which includes an upper water tank 1, a heat exchange mechanism 2 and a lower water tank 3 arranged from top to bottom. The upper water tank 1, the heat exchange mechanism 2 and the lower water tank 3 are connected in sequence. A fan cover 4 is installed on the side of the heat exchange mechanism 2 facing the excavator's drive device (not shown in the figure). Support plates 5 for connecting the excavator's slewing platform are symmetrically arranged at the bottom of the lower water tank 3.

[0038] The heat exchange mechanism 2 has protruding first connecting plates 21 on both sides of the fan shroud 4. The fan shroud 4 is placed between the two first connecting plates 21. The fan shroud 4 has a second connecting plate 41 at the position corresponding to the first connecting plate 21. The second connecting plate 41 is installed on the first connecting plate 21. The fan shroud 4 has a cavity 42 for accommodating the fan. The bottom of the fan shroud 4 has a cleaning port 43 communicating with the cavity 42. The fan shroud 4 has a cleaning door 6 rotatably connected at the position corresponding to the cleaning port 43. A pad 44 is provided at the position where the fan shroud 4 and the cleaning door 6 are rotatably connected.

[0039] With the above structure, the arrangement and connection of the upper water tank 1, heat exchange mechanism 2, and lower water tank 3 facilitates the flow of water from the upper water tank 1 into the heat exchange mechanism 2 and along the heat exchange mechanism 2 to the lower water tank 3. The cooperation between the first connecting plate 21 of the hood 4 and the first connecting plate 21 of the heat exchange mechanism 2 improves the stability of the hood 4 installed on the heat exchange mechanism 2 and reduces the required installation space. A support plate 5 is arranged at the bottom of the lower water tank 3, allowing the entire heat dissipation device to be installed on the excavator. The cooperation between the cleaning door 6 and the cleaning port 43 facilitates the cleaning of dust from the heat exchange mechanism 2, ensuring its heat exchange effect. The pad 44 provides protection for the hood 4.

[0040] In one embodiment, see Figure 1 , Figure 2 , Figure 4 and Figure 5The cleaning door 6 includes a door body 61. One side of the door body 61 is rotatably connected to the fan cover 4 via a hinge 62. A pad 44 is disposed between the hinge 62 and the fan cover 4. The other side of the door body 61 is fixed to the drain tank 3 via a hand-tightened screw 63. In practical applications, the hinge 62 facilitates the rotational connection of the door body 61 to the fan cover 4. The pad 44 protects the fan cover 4 at the position corresponding to the hinge 62, preventing damage to the fan cover 4 when the hinge 62 rotates. The hand-tightened screw 63 secures the other side of the door body 61 to the drain tank 3, thereby improving the connection stability between the drain tank 3 and the heat exchange mechanism 2.

[0041] A bending plate 611 is provided on the side of the door 61 facing the hand-tightening screw 63, and the bending plate 611 bends towards the lower water tank 3. In practical application, the setting of the bending plate 611 can improve the sealing effect between the door 61 and the lower edge of the cleaning port 43, and prevent dust from leaking out.

[0042] A fixing plate 612 is provided at the position of the bending plate 611 corresponding to the hand screw 63, and the hand screw 63 passes through the fixing plate 612. In actual use, the fixing plate 612 allows the hand screw 63 to pass through, so as to facilitate the installation of the door 61 onto the drain tank 3.

[0043] A fixing sleeve 32 is provided on the drain tank 3 at the position corresponding to the hand-tightening screw 63, and the hand-tightening screw 63 is threadedly connected to the fixing sleeve 32. In actual use, the fixing sleeve 32 makes it easy for the hand-tightening screw 63 to be screwed into the fixing sleeve 32, thereby fixing the door 61 to the drain tank 3.

[0044] In one embodiment, see Figure 1 , Figure 2 and Figure 3 The upper water tank 1 is equipped with an inlet pipe 11, and the lower water tank 3 is equipped with an outlet pipe 31. A circulation pump (not shown in the figure) is connected between the inlet pipe 11 and the outlet pipe 31. In practical applications, the water in the upper water tank 1 and the lower water tank 3 can be circulated by connecting the circulation pump between the inlet pipe 11 on the upper water tank 1 and the outlet pipe 31 on the lower water tank 3.

[0045] In one embodiment, see Figure 1 , Figure 2 and Figure 4 The fan cover 4 has a through hole 421 on the side facing the excavator's drive unit, which communicates with the cavity 42. In practical applications, the through hole 421 can provide space for the fan, so that the fan can pass through the through hole 421 and be placed in the cavity 42.
