Problems solved by technology

[0003] The traditional test method for the cooling air volume of special vehicles is to use an anemometer or a hot wire meter to test the windward side of the air intake grille at a fixed point. Since the motion vector of the vehicle cooling air volume is uneven, the traditional test method will produce relatively A large error, in the actual use process, usually causes the cooling air volume to not meet the design value, which will cause the performance of the cooling system to deteriorate, cause vehicle failure, and affect the normal use of the vehicle

Embodiment Construction

[0026] In order to make the purpose, content, and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] Such as figure 1 As shown, the present invention provides a special vehicle cooling air volume testing device based on a testable grille. This device improves the air intake grille and installs two sets of air volume measuring devices on the air intake grille. The two sets of air volume The measuring devices are arranged relative to each other. Among them, the wind speed and wind measurement piece is embedded, installed at the air inlet of the cooling air duct of the real vehicle, and a plurality of wind speed and wind measurement pieces 4 are interspersed and arranged at equal intervals. Each group of air flow measurement devices includes a plurality of wind speed and wind measurement sheets 4 arranged at equa...

Abstract

The invention relates to a special vehicle cooling air volume test device and method on the basis of a testable grating and relates to the technical field of vehicle engineering. The special vehicle cooling air volume test device performs testable design on an air inlet grating of a vehicle, not only can test and obtain cooling air volume information of a vehicle, but also is integrated with the air inlet grating, does not adopt extra test equipment and does not influence an air inlet flow area of the vehicle.

Description

technical field [0001] The invention relates to the technical field of vehicle engineering, in particular to a test device and method for cooling air volume of a special vehicle based on a testable grille. Background technique [0002] At present, the heat dissipation of the cooling system of special vehicles has doubled, but the increase in the layout space of the vehicle cooling system is extremely limited, which has brought about increasing difficulty in the design of the vehicle cooling system, and the traditional cooling system design can no longer meet the demand. The cooling air volume is the decisive factor to determine the design of a cooling system and the cooling effect. [0003] The traditional test method for the cooling air volume of special vehicles is to use an anemometer or a hot wire meter to test the windward side of the air intake grille at a fixed point. Since the motion vector of the vehicle cooling air volume is uneven, the traditional test method will...
