Embodiment Construction

[0016] The present invention will be described in detail below with the best embodiment.

[0017] Such as figure 1 As shown, a double-joint tracked vehicle airtight cabin airway system is composed of an air intake end, an air duct and an exhaust end; 1 is equipped with an automatic control water-sealed intake valve 2, and the automatic control water-sealed intake valve 2 is automatically controlled by an electric control push rod or a hydraulic control push rod. The control button for automatically controlling the water-sealed intake valve 2 is set in the cab; the intake end also includes an auxiliary air intake 3 arranged at the front end of the double-section crawler vehicle body, and the opening of the auxiliary air intake is located at the wading area of ​​the double-section crawler vehicle. Above the waterline. The air duct is composed of the power cabin 5 and the interior of the double tracked vehicle body 4 and extends to the rear of the vehicle; the exhaust end is ar...

Abstract

The invention relates to the technical field of engineering, and particularly relates to an air passage heat dissipation system in a two-section crawler sealed cabin. The system comprises an air inletend, an air duct and an exhaust end, wherein the air inlet end is an air inlet formed in a double-section crawler body, and the air inlet end further includes an auxiliary air inlet channel formed inthe front end of the double-section crawler body; the exhaust end is arranged at the tail of the two-section crawler; the air duct is composed of a power cabin and the interior of the double-sectioncrawler body and extends from the air inlet end to the crawler tail exhaust end; and a spoiler for preventing airflow disturbance is arranged in the air duct, is arranged in a forward exhaust direction in the double-section crawler body and extends to the tail exhaust end of the crawler. The system solves the problems that an existing double-section crawler intake valve is poor in watertight effect, hot air in the air duct is exhausted easily to generate turbulent flow, the heat dissipation efficiency is low, and a water temperature of an engine is too high.

Description

technical field [0001] The invention relates to the field of engineering technology, in particular to an air passage heat dissipation system in a sealed cabin of a double-segment crawler vehicle. Background technique [0002] The air intake and heat dissipation air ducts of the double-joint tracked vehicles in the prior art adopt manual control of intake valves, and the inside of the air ducts is the inner cavity of the vehicle body, and the exhaust end at the rear of the vehicle adopts the form of natural exhaust. In the prior art, the manual control of the intake valve has poor watertight effect, and the hot air discharge in the air duct is prone to turbulent flow, and the heat dissipation efficiency is low, resulting in excessively high engine water temperature. Contents of the invention [0003] The invention provides an air duct system for a sealed compartment of a double-joint crawler vehicle, which solves the problem of poor watertight effect of the intake valve of ...
