A tractor cab column side air duct structure

Abstract

This utility model relates to the field of vehicle cab ventilation technology, and discloses a side air duct structure for a tractor cab column. It includes a column with a side air duct shell on top, comprising a top-wide, bottom-narrow collecting section shell, a lower connecting section shell, and a guide shell on the upper part of the connecting section shell. All three are connected. A closed partition is located inside the side air duct shell, and an air guide port is located on the outer wall of the guide shell. An air guide pipe connects the upper end of the partition to the collecting section shell. This utility model reduces transmission loss, lowers wind resistance, and avoids eddy current generation. The collecting section shell gathers airflow to reduce loss, while the guide and connecting section shells ensure a smooth path and reduce wind resistance. The closed partition forms a closed chamber to improve efficiency, the air guide pipe buffers airflow to prevent impact, and the air guide port enables directional output. This solves the problems of high loss, high wind resistance, and erratic direction in existing air ducts.
