Abstract
The invention relates to an explosion-proof motor shell achieving good cooling performance. The explosion-proof motor shell comprises a cylindrical shell body, and one end of the cylindrical shell body is provided with an end cover. The outer circumferential wall of the cylindrical shell body is evenly provided with multiple strip-shaped trapezoidal cooling fins and T-shaped cooling fins. The strip-shaped trapezoidal cooling fins and T-shaped cooling fins are alternately arranged on the outer wall of the shell body. A hole is formed at the center of the end cover. An annular protrusion is arranged around the hole and protrudes from the end cover. A circle of arc cooling fins are evenly distributed around the annular protrusion. The inner wall of the shell body is provided with strip-shaped tooth ripples which are annularly distributed. The inner wall of the shell body is coated with an explosion-proof material layer. According to the explosion-proof motor shell, because the cooling fins are arranged on the motor shell, the operation temperature of a motor is lowered; due to the explosion-proof material layer, the motor is prevented from exploding in high-speed operation, and the safety level is effectively improved; the explosion-proof motor shell is easy to manufacture, high in stability, good in cooling performance, and good in anti-corrosion property.
Description
Technical field
The present invention relates to technical field of motors, the explosion-proof motor shell that especially a kind of thermal diffusivity is good.
Background technology
Current most motor case is all manufactured by cast iron, the shortcoming of cast iron is quality weight, heat conductivility is undesirable, and motor works long hours, heating can affect its performance, makes its job insecurity, existing is all generally that external increase fan dispels the heat to it, this radiating effect is bad, and the quality of aluminium is light, has good heat conductivility, be formed from aluminium the gelled motor case of tool, operating motor can be allowed to dispel the heat better.But because technology limit, the aluminium motor case that the fin density can only casting several kilowatts now is comparatively dredged, comparatively large and there is not only the close but also motor case of the fin of Bao Youkuan be temporarily difficult to one-body molded with aluminum casting power, and easily burst during motor High Rotation Speed, security performance is poor, and does not possess etch-proof performance.
Summary of the invention
The technical problem to be solved in the present invention is: for overcoming above-mentioned Problems existing, provide the explosion-proof motor shell that a kind of thermal diffusivity is good.
The technical solution adopted for the present invention to solve the technical problems is: a kind of explosion-proof motor shell, comprise the cylindrical housings that one end has end cap, described cylindrical housings periphery wall is evenly provided with the trapezoidal radiating fin of complex root strip and T-shaped fin, described trapezoidal radiating fin and T-shaped fin is spaced is arranged on housing exterior walls, described end cap central place is provided with perforate, a circle annular protrusion of outstanding end cap is provided with around described perforate, in order to strengthen heat radiation, the equally distributed arc heat sink strip of a circle is provided with around described annular protrusion, described inner walls is provided with the bar shaped groove of annular spread, described inner walls is coated with explosion-proof lamp layer, prevent motor from bursting when running up, effectively improve safe class.
Further, in order to play effective anticorrosion ability, described housing exterior walls is coated with corrosion-resistant coating.
Further, described trapezoidal radiating fin, T-shaped fin are connected by soldering with housing outer surface, and described housing, trapezoidal radiating fin and T-shaped fin are aluminum alloy materials and make.
Further, in order to heat radiation grade, the quantity of described arc heat sink strip is four.
The invention has the beneficial effects as follows, explosion-proof motor shell of the present invention owing to being provided with heating panel on motor housing, reduce temperature when motor runs, be provided with explosion-proof lamp layer, preventing motor from bursting when running up, effectively improve safe class, make simple, stability is high, thermal diffusivity good, and has good anticorrosive property.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
