Description

Technical Field

[0001] The utility model relates to the technical field of electric loaders, in particular to a cooler installation structure of an electric loader. Background Art

[0002] An electric loader is a loading tool driven by an electric motor. When working, the motor, gearbox and other components of the electric loader will generate a lot of heat. If the heat is not dissipated in time, it will affect the normal operation of the electric loader. Therefore, the electric loader needs a cooler to dissipate heat to ensure the normal operation of the electric loader. The cooler usually includes a radiator and a fan. When the motor is working, the heat generated is absorbed by the coolant and then enters the radiator under the transportation of the pump body. It is transferred to the heat pipe through the heat sink on the radiator, and then the fan transfers the heat to the surrounding air, thus ensuring the heat dissipation of the electric loader and ensuring its normal operation.

[0003] After searching, the patent authorization announcement number CN 210371956 U discloses the installation structure of the gearbox cooler of the electric loader, "including a cooler, which is connected to the gearbox through an oil inlet pipe and an oil outlet pipe, and the cooler is installed on the outside of the bracket. The bracket includes a vertical plate, and the vertical plate is a whole plate structure. Both sides of the bottom of the vertical plate are provided with anchor connecting plates, and the anchor connecting plates are fixedly connected to the rear frame of the electric loader; the electric fan is placed on the outside of the cooler, and the electric fan is fixedly connected to the connecting frame, and the connecting frame is fixedly connected to the fan cover of the cooler." Although the above-mentioned installation structure solves the problem of heat dissipation of the hydraulic transmission oil in the gearbox, because its anchor connecting plate is fixed to the rear frame of the electric loader by bolts, it is not convenient to disassemble and assemble, and it is not convenient for personnel to inspect or clean the cooler.
