Description

A kind of heat radiation case

Technical field

The utility model relates to a kind of radiator, specifically, relates to a kind of heat radiation case that is applicable to engineering mechanical device, belongs to field of mechanical technique.

Background technology

At present, be applied to the heat radiation case on the large-scale diesel engine engineering machinery, its radiating tube adopts copper pipe and fin welding or the support of expanding to form usually, in the process of using, because cold and hot exchange is frequent, can produce stress on the radiating tube, solder joint ftractures easily, causes between fin and the copper pipe to form the gap, produce thermal resistance, influence radiating effect, because the copper pipe layout is intensive, the place use big at dust storm is easy to block ventilating hole channel, cause heat to scatter out, because copper pipe is intensive,, be not easy to clean simultaneously so airspace is little; Serious meeting causes plant equipment to break down, and uses full copper pipe to make, and causes the production cost height.

The another kind of concrete prioritization scheme of gilled tube has several axial fractures on the excircle of described fin, this fracture is V-shaped.The needs that can adapt to different medium help stoping the boundary-layer expansion.

The prioritization scheme of fracture, the quantity of described fracture are 10-36.

A kind of concrete prioritization scheme of fracture, the angle of described fracture are 30 °-60 °.

The another kind of concrete prioritization scheme of fracture, the degree of depth of described fracture is the 1/2-1/8 of fin height.

The utility model is taked above technical scheme, has the following advantages: gilled tube adopts copper, aluminum metal is rolling forms, in conjunction with tight, the heat transference efficiency height, fin rational in infrastructure meets the gradient requirement that temperature reduces in fin, the heat exchange efficiency that carries out heat exchange between the medium is higher, both avoided to further improving the height that radiating efficiency infinitely increases fin, not only can not strengthen heat dispersion, it is big to take up room on the contrary, waste material, and increased resistance, also be not easy to the problem of cleaning; Simultaneously, the area of dissipation of having avoided reducing for reducing cost fin does not again reach the problem of the radiating effect that requires, and the V-arrangement fracture is set on the excircle of fin, can adapt to the needs of different medium, helps stoping the boundary-layer expansion; Because rolling fin has been expanded area of dissipation on the gilled tube external diameter, so gilled tube does not need tight arrangement, has so just increased blow vent, reduced resistance, be more convenient for cleaning, especially be fit to the big region of dust storm and use, owing to use the copper aluminum to do, reduced cost.
