Description

Technical Field

[0001] The present invention relates to the technical field of loader equipment, in particular to a temperature control system for a loader lithium battery. Background Art

[0002] The Chinese patent document with the authorized publication number CN216413182U and the publication date of 20220429 discloses a lithium battery mounting bracket for excavators and loaders that is resistant to high vibration intensity working conditions. The existing lithium battery mounting bracket is generally troublesome to install the lithium battery, which is very inconvenient when it needs to be disassembled for maintenance, and generally uses springs for shock absorption, which will affect the shock absorption effect over time. The above problems are improved and optimized; that is, the shock absorption mechanism includes a slide plate slidably connected between the inner wall of the installation frame, the top of the slide plate is fixedly connected to the bottom of the placement box, a hollow cylinder is fixed to the bottom of the inner wall of the installation frame, and a shock absorption column is slidably connected to the inner wall of the hollow cylinder. The top of the shock absorption column is fixedly connected to the bottom of the slide plate, and the bottom end of the shock absorption column is fixed with a first shock absorption magnetic block, and the inner wall of the hollow cylinder is fixed with a second shock absorption magnetic block used in conjunction with the first shock absorption magnetic block. By setting the first and second shock absorption magnetic blocks in the shock absorption mechanism, since the spring is prone to lose elasticity after long-term use, it is convenient to replace the spring for shock absorption, and the shock absorption effect is good.

[0003] In the above scheme, the heat dissipation of the lithium battery is achieved by setting a cooling fan at one end of the placement box for blowing cooling, and a dustproof net is set at the other end of the placement box, which can form a simple air flow with the cooling fan, but the air circulation effect is poor; in this process, there are also problems, on the one hand, the cooling fan is always in working state, and the heat generated by itself will also affect the work of the lithium battery, resulting in low heat dissipation efficiency; secondly, the temperature control work of the lithium battery cannot be adjusted and cooled according to actual needs, that is, when the temperature of the lithium battery is too high, its temperature cannot be controlled in time and effectively. Over a long period of time, it will cause damage to the lithium battery and affect its energy supply work. Therefore, further improvement and optimization are needed.

[0004] To this end, the present invention proposes a loader lithium battery temperature control system to solve the above problems. Summary of the Invention
