Forced air cooling type heat dissipation case

Abstract

The invention discloses a forced air cooling type heat dissipation case which comprises a case body and a radiator installed in the case body. The case body is formed by splicing a bottom plate, a left side plate, a right side plate, a front panel, a rear panel and a cover plate, and a transformer and a power module are mounted on the bottom plate; and the radiator comprises a heat conducting plate which is flatly laid on the power module. According to the forced air cooling type heat dissipation case, the internal power module is cooled through the fan, forced air cooling of the radiator and natural heat dissipation of the outer surface of the case body, the effects of heat dissipation, air flow and air steering are achieved through heat dissipation teeth, heat dissipation straight fins and air flow channels; an inclined face is arranged at the position of an internal step so as to realize transition, the air flow resistance is reduced, the heat dissipation efficiency and the heat dissipation effect of the case are greatly improved, and thus, the durability of the case is enhanced, and long-time use of the air-cooled heat dissipation case is facilitated.

Description

technical field [0001] The invention relates to the field of aviation airborne equipment, in particular to a forced air-cooled cooling case. Background technique [0002] At present, forced air cooling is widely used in aviation airborne equipment. For electronic equipment with high heat flux density, natural cooling cannot meet the heat dissipation requirements of electronic equipment. At this time, air cooling is required for heat dissipation. [0003] The traditional chassis and radiator are independent structures, increasing the number of installed structural parts, making it impossible to form a good heat transfer path between the chassis and radiator, and the weight is heavy. [0004] For electronic equipment cooled by a built-in fan, the air is thin at high altitudes and the cooling effect is reduced. It is necessary to use both the natural heat dissipation of the chassis and the forced convection driven by the fan to dissipate heat. Contents of the invention [00...
