Air-blowing type cooling system

Abstract

The invention discloses an air-blowing type cooling system which comprises a machine cover, a fan, an air outlet partition net, a cooler, an air guide cover and a flow guide pipe. The fan is installedon one side of the machine cover and used for blowing air into a containing space. The air outlet partition net is installed on the other side of the machine cover and is right opposite to the fan. The air outlet partition net is provided with an air outlet. The cooler is arranged in the containing space and located between the fan and the air outlet partition net. The peripheral edge of the cooler is fixed to the machine cover and is perpendicular to the air-blowing direction of the fan. The air guide cover is of a hollow structure, one end of the air guide cover is right oppositely connected with the fan, and the other end of the air guide cover abuts against the cooler. An air guide channel is defined by the air guide cover, the fan and the cooler. The flow guide pipe comprises a coverbody buckled on the side, away from the fan, of the cooler and a pipe body bent and extending from the cover body and penetrating through the machine cover to communicate with the outside. Compared with a related technology, the air-blowing type cooling system is good in cooling effect and high in reliability.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a blowing heat dissipation system. Background technique [0002] A grader is an earthwork machine that uses a scraper to level the ground. It is the main machine used for shaping and leveling operations in earthworks. [0003] The heat dissipation of the engine compartment of the grader mainly adopts the blowing heat dissipation system to realize the blowing heat dissipation. In the actual operation process, due to the large workload, the heat output of the engine increases sharply. In addition, the layout of the engine compartment is very tight, and the environment is bound to be harsh. Therefore, the requirement for heat dissipation capability gradually increases. The blowing heat dissipation system is also increasingly used in plateau areas. Due to the relatively high altitude in plateau areas, the boiling point of the cooling medium is lower, and the critical te...

AI Technical Summary

Problems solved by technology

The blowing heat dissipation system is also increasingly used in plateau areas. Due to the relatively high altitude in plateau areas, the boiling point of the cooling medium is lower, and the critical temperature for the phenomenon of "burning pot" is lower than other areas by more than 5°C. Therefore, if the heat dissipation capacity of the engine compartment is insufficient, The grader cannot guarantee normal work, so the increasingly harsh environment and working conditions pose a more severe challenge to the heat dissipation of the engine compartment of the grader
