Description
Technical Field
The invention belongs to the field of automobile cooling systems, particularly relates to the technical field of automobile engine radiators, and particularly relates to an automobile multichannel radiating tube and a radiator. This radiator adopts the multichannel cooling tube, and the use of the multichannel cooling tube of high strength, low wall thickness effectively improves the structural strength and the heat-conduction ability of radiator.
Background
At present, flat tubes, sand leakage tubes and B-shaped tubes are commonly adopted by the radiator of the vehicle engine. For the flat pipe, when the width of the radiating pipe is larger than 26mm, the strength of the radiating pipe is reduced, the pressure bearing capacity of the radiating pipe is reduced, deformation is easy to generate, and leakage is easy to cause. Therefore, after the width of the flat pipe is increased, the wall thickness is increased to ensure the strength, and the thermal resistance of the radiating pipe is increased after the wall thickness is increased, thereby reducing the heat transfer performance. For the sand leakage pipe, the protruding structures are additionally arranged in the middle of the pipe, and the protruding structures on the upper wall surface and the lower wall surface are connected together through brazing, so that the structural strength of the pipe is improved, and the width of the radiating pipe is increased. The processing precision of the projection is high, if the precision can not be achieved, the projection in the middle is not welded or the welding is not reliable, so that the strength of the radiating pipe is reduced, the deformation is easy to generate, and the leakage is generated. For a sand trap, the outer portion of the protrusion position cannot contact the heat dissipation band, resulting in a reduction in the heat transfer capability of the heat sink. For the B-shaped pipe, the existing problem is similar to that of the sand leakage pipe, and the middle welding point plays a great role in the strength of the radiating pipe, so whether welding is reliable or not directly influences the strength of the radiating pipe. For the flat pipe, sand leakage pipe and B type pipe at present, the ubiquitous structural strength is poor, the problem that the bearing capacity is low. Meanwhile, as the existing radiating pipe uses one or two fluid channels, the contact area of fluid and a heat transfer wall surface is small, the internal radiating surface is small, and the turbulence intensity of a fluid area is small, so that the radiating of the radiator is not facilitated.
