Radiator for a towing vehicle and method of operation thereof

Abstract

The present application belongs to the general vehicle technical field, and particularly relates to a heat dissipation device for a vehicle, and more particularly to a heat dissipation device for a tractor and a working method thereof. The heat dissipation device for the tractor comprises at least two groups of parallel arranged grid plates, the middle part of each group of the grid plates is rotatably arranged on the inner wall of a fixed frame through a hinge shaft, and an adjusting assembly is slidably arranged on the inner wall of the fixed frame and comprises symmetrically arranged telescopic adjusting blocks, the outer end of each of the telescopic adjusting blocks is abutted against the grid plate. When the telescopic adjusting blocks move to the innermost end of the grid plates, the telescopic adjusting blocks are tightly abutted against the inner end side wall of each of the two grid plates respectively, so that the air inlet amount between the two grid plates is in a minimum state. When the telescopic adjusting blocks move to the outermost end of the grid plates, the telescopic adjusting blocks are elongated outward and respectively push the outer end of the adjacent two grid plates, so that the outer end of the two grid plates is turned outward, and a V-shaped flow guide channel with an opening towards the coming flow direction is formed between the two grid plates.
