Description
Technical field
The utility model relates to a kind of motor, particularly a kind of water-cooled machine.
Background technology
The water-cooled machine shell is the cooling system of on the metal-back of motor, laying the course, and takes away the inner heat of motor casing through flowing water, thereby reduces the motor internal temperature.Existing most of water-cooled machine shell adopts inner casing and shell to cast separately, at inner casing and the shell periphery circumferential helicla flute of getting on the bus out, carries out the welding of both ends of the surface after inner casing and shell lump together again, or with adhesive bond together.Water channel in the motor casing is processed into vertical water channel can make the motor casing bulk temperature more even; But vertical water channel of existing water-cooled machine shell is parallel with the center line of water-cooled machine shell, and the comparison of turning round is anxious, and the cooling water inlet on the end cap and the current flow process between the coolant outlet are longer; The disclosed structure of Chinese patent document CN201450384U for example; Therefore current have some setbacks, and water resistance is big, need very high hydraulic pressure to supply water.In addition, existing water-cooled machine shell is difficult to the test through pressure testing >=0.5Mpa, and manufacturing process is complicated, makes trouble, and forms waste product easily.
Summary of the invention
The purpose of the utility model is to provide vertical water-cooled machine shell of the test that a kind of current are smooth and easy, water resistance is little, the current flow process short and can be through pressure testing >=0.5Mpa.
The technical scheme that realizes above-mentioned purpose is: a kind of water-cooled machine shell; Comprise the motor casing main body, said motor casing main body comprises outer tube wall and inner tube wall, and the outer tube wall of said motor casing main body and inner tube wall casting become an integral body; The two ends of said motor casing main body be sealedly and fixedly connected respectively corresponding first end cap and second end cap; Have cooling water inlet and coolant outlet on the said motor casing main body, be cast with many left and right withes between said outer tube wall and the inner tube wall, said many left and right withes are indenting shape and arrange; Promptly when the left end of a left withe and first end cap join, leave second space between its right-hand member and second end cap; The left end of the right withe adjacent with an above-mentioned left withe then and leave first space between first end cap; Its right-hand member and second end cap join; Form vertical water channel between the sidewall of said every adjacent two left and right withes; First gap and second gap form the first circumferential water channel and the second circumferential water channel respectively, and said vertical water channel vertically extends along the motor casing main body twist, and vertically the pitch angle alpha will of the center line of water channel is 5 ° ~ 30 °; It is cooling water channel that said vertical water channel is communicated with the first circumferential water channel and the second circumferential water channel; Cooling water channel one end communicates with cooling water inlet, and the other end communicates with coolant outlet, and said cooling water inlet is positioned at first gap and is connected with the first circumferential water channel; Said coolant outlet is positioned at second gap and is connected with the second circumferential water channel, and coolant outlet is positioned at the dorsal part of cooling water inlet simultaneously.
The circumferential width of the link of said left and right withe is greater than free-ended circumferential width.
Angle β between the two side of said left withe is 5 ° ~ 60 °, and the angle γ between the two side of right withe is 5 ° ~ 60 °.
When angle β between the two side of said left and right withe and γ equated, left withe was consistent, in the opposite direction with right withe shape, and vertically water channel equates with the vertical aisle spare of water (flow) direction everywhere.
Said cooling water inlet is positioned at the top of motor casing main body; Said coolant outlet is positioned at the bottom of motor casing main body.
After adopting said structure; Owing to be cast with many left and right withes between outer tube wall and the inner tube wall; Said many left and right withes are indenting shape to be arranged, forms vertical water channel between the sidewall of said every adjacent two left and right withes, and first gap and second gap form the first circumferential water channel and the second circumferential water channel respectively; Said vertical water channel vertically extends along the motor casing main body twist; Vertically the pitch angle alpha will of the center line of water channel is 5 ° ~ 30 °, so current are smooth and easy, water resistance is little, need not very high hydraulic pressure and supplies water; Also since cooling water inlet be positioned at first gap and be connected with the first circumferential water channel; Coolant outlet is positioned at second gap and is connected with the second circumferential water channel, and coolant outlet is positioned at the dorsal part of cooling water inlet simultaneously, so cooling water is after cooling water inlet entering motor casing main body; Current are divided into two-way; Converge the back again at the coolant outlet place and flow out, the current flow process is short, good cooling results.The cooling water channel of the utility model is to cast with the motor casing main body to form, and can reach pressure testing >=0.5MPa test, and manufacturing procedure is few, makes simply, and rate of finished products is high.
