Embodiment 1

[0025] The length of wind gathering cover 4 is fixed.

Embodiment 2

[0027] The wind collecting cover 4 is retractable. In this embodiment, the wind collecting cover 4 is a bellows, and the bellows is preferably a metal bellows. One end of the bellows is connected to the radiator 3, and the other end is connected to the swirler 5, and an adjusting device for adjusting the distance between the swirler 5 and the radiator 3 is provided. The adjusting device includes a cylinder fixed on the radiator 3, and the piston head of the cylinder is fixedly connected with the outer wall of the swirler 5. In actual working conditions, the length of the wind gathering cover 4 can be adjusted according to the speed of the fan 1.

Abstract

The invention relates to the technical field of heat dissipation systems, in particular to a bulldozer desert type heat dissipation system. The bulldozer desert type heat dissipation system comprisesa fan, an air guide cover, a radiator and a swirler, one side of the air guide cover is provided with an inlet, the other side of the air guide cover is provided with an outlet, the fan is arranged inthe outlet, the radiator is connected with the inlet of the air guide cover, an air gathering cover used for collecting sand and dust in rotational-flow gas is arranged between the radiator and the swirler, and a dust discharging opening is formed in the bottom of the air gathering cover. According to the bulldozer desert type heat dissipation system, on the premise that the performance of the heat dissipation system is guaranteed, cooling air sucked into the radiator through a fan 1 is swirled, fine sand in the air is separated and removed before passing through the radiator through swirlingcentrifugation, the clean air undergoes heat exchange through the radiator, so that the abrasion caused by impact of fine sand particles to the radiator is reduced, and the service life of the radiator is prolonged; and meanwhile, due to the fact that sundries are removed, the radiator is not prone to blockage to the greater extent, and the maintenance and cleaning period is longer.

Description

technical field [0001] The invention relates to the technical field of heat dissipation systems, in particular to a desert type heat dissipation system for bulldozers. Background technique [0002] The principle of the existing bulldozer cooling system is to cool the radiator with water, oil, and intercooling by fan blowing or suction. In order to improve the heat exchange efficiency and reduce the cost, the radiator is generally made of aluminum brazed, and the wall thickness of the cooling channel is generally 0.8-1.2mm. [0003] Under certain conditions of the radiator, increasing the wind speed passing through the radiator can improve the performance of the cooling system. The wind speed of the radiator can generally reach 10m / s. [0004] When working in desert areas, there are a lot of fine sand in the air, and the fine sand is carried by the wind through the radiator, which will inevitably cause impact and wear on the channels of the radiator, resulting in heat dissi...
