AI Technical Summary

Technical Problem

Although the liquid cooling system of the existing electric luggage tractor can effectively dissipate heat, it increases the vehicle weight and space occupied, affecting the load capacity, mobility and overall design layout.

Method used

A new tractor heat dissipation structure is designed. By embedded cooling plates made of lightweight materials in the bottom of the cab, it directly contacts the battery module to form a direct heat conduction path, and integrates the heat dissipation structure with the vehicle main structure, using the vehicle frame and shell as auxiliary paths for heat dissipation.

Benefits of technology

The new tractor heat dissipation structure reduces weight and space occupation, while maintaining efficient heat dissipation performance, ensuring the long-term and stable operation of the battery module, and improving load capacity and maneuverability.

Abstract

The utility model relates to the technical field of tractors, in particular to a novel tractor heat dissipation structure which comprises a tractor body, driving wheels are arranged at the four corners of a chassis of the tractor body, a cab is arranged at the front end of the tractor body, and a power chamber is arranged at the bottom end of the cab through a partition plate. A battery module for providing a power source for the tractor body is arranged in the power chamber, a cooling plate integrated on the inner wall of the bottom of the cab is arranged at the bottom of the power chamber, the battery module is placed at the top of the cooling plate, and rectangular copper sheets for limiting the two sides of the battery module are arranged on the two sides of the interior of the power chamber. According to the novel heat dissipation structure of the tractor, the liquid cooling system and the tractor body are integrally designed, the weight and occupied space are reduced, meanwhile, efficient heat dissipation performance is kept, and long-term stable operation of the battery module is guaranteed.
