Abstract

The invention discloses a snakelike evaporating dish gravity assisted heat pipe radiator for an electric vehicle battery pack. The snakelike evaporating dish gravity assisted heat pipe radiator is composed of a snakelike evaporating dish, a finned tube condenser, a working medium, a heating piece, a condenser cover and a working medium, wherein the snakelike evaporating dish and the finned tube condenser are connected in a sealing manner; welding flux is arranged on the outer surface of a connecting pipe of the finned tube condenser; an axial groove is formed in the inner surface, and the cross section of the groove is triangular or rectangular, trapezoidal, inverted trapezoidal or circular-arc-shaped; corrugated sheets, sawtooth sheets and skylight sheets are arranged on the surfaces of radiating fins; the snakelike evaporating dish has two structural forms, namely, a special-shaped circular tube type snakelike evaporating dish and a blowing expansion type snakelike evaporating dish; the two evaporating dishes are in surface contact with the surface of a battery; and the working medium is distilled water or liquid ammonia added with an anti-corrosion agent. The snakelike evaporating dish gravity assisted heat pipe radiator has the characteristics of fast heat dissipation, large heat dissipation amplitude, light weight, simple structure, safety, low price and the like. The snakelike evaporating dish gravity assisted heat pipe radiator is suitable for existing electric vehicles and newly developed electric vehicle refrigerating systems.

Description

technical field [0001] The invention belongs to a heat pipe radiator, in particular to a serpentine evaporating dish gravity heat pipe radiator for an electric vehicle battery pack and a manufacturing method thereof. Background technique [0002] At present, compared with fuel vehicles, electric vehicles are slower to charge and have lower battery life than fuel vehicles. [0003] It is the power battery that affects the charging speed and endurance of electric vehicles. When the charging speed is fast, the battery heats up, and when the battery works under high temperature conditions, its life is reduced. [0004] Lithium batteries are generally used in electric vehicles. Lithium batteries generate heat during charging and discharging. When the temperature of lithium batteries is too high or too low, their lifespan will drop sharply. It can be seen that if the charging and discharging speed of electric vehicles is to be improved, the heat dissipation and heating problems...
