The invention provides a body tube cooling device with a fin type turbulent flow structure. The body tube cooling device comprises an upper fixing part, a lower fixing part, a cooling device body, a water inlet and a water outlet. The upper fixing part and the lower fixing part are arranged at the upper end and the lower end of the cooling device body correspondingly. The water inlet and the wateroutlet are formed in the upper side and the lower side of the wall face of the cooling device body correspondingly. The body tube cooling device comprises multiple fin type turbulent flow vanes. Allthe fin type turbulent flow vanes are arranged on the inner wall of the cooling device body in the circumferential direction of the cooling device body. Each fin type turbulent flow vane is arranged on the inner wall of the cooling device body in the axial direction of the cooling device body. The outer wall of each fin type turbulent flow vane is provided with multiple fins.
Description
technical field [0001] The invention relates to a cooling device, in particular to a barrel cooling device with a fin-type turbulence structure. Background technique [0002] During the continuous shooting of the launching device, the temperature of the barrel continues to rise, which seriously threatens the safety of the propellant and the service life of the barrel. Many launchers use external cooling to reduce barrel temperature. The cooling water flow in the traditional external cooling device has no direction and regularity, and it is easy to form a flow dead zone, which reduces the heat dissipation efficiency; the heat dissipation effect of the flow dead zone is poor, and it is easy to cause uneven cooling of the barrel and cause the barrel to bend. Contents of the invention [0003] The object of the present invention is to provide a barrel cooling device with a fin-type turbulence structure, which can ensure uniform cooling of the barrel while improving the coolin...
