Description
Technical field
The utility model relates to the heat abstractor field, is specially the water cooling plant that is used for motor.
Background technology
Can produce a large amount of heats during machine operation, must in time be discharged, otherwise temperature rise surpasses the rated value of motor, gently then influences electric machine operation state and useful life, heavy then burn motor and cause accident.The motor cooling comprises that interior cooling of casing and casing cool off outward, and the outer cooling of casing can be adopted air-cooled or water-cooled.Because the thermal capacity of water is big, can also adopt pump to give forced circulation, thereby the cooling effect of water-cooled is better than air-cooled.A kind of cooling device that adopts water channel is arranged at present, as shown in Figure 1, at motor case 11 external fixation water channel inner housing 12 is arranged, water channel inner housing 12 closely contacts with motor case 11, be fixed with a spiral helicine water channel 15 between water channel inner housing 12 and the water channel shell body 13, one end junction of water channel 15 and water channel shell body 13 is water inlets 14, and other end junction is a delivery port 17, is lined with cooling fin 16 between each tooth of water channel 15 spirals.There is following defective in this structure: water channel shell body 13 is enclosed within outside the water channel inner housing 12, be welded to connect between the two, because the existence of weld seam, the thickness of water channel shell body 13 can't utilize, such as will be by the screw end cap time, screw can only be screwed on the water channel inner housing 12 when continue installing.When the wall thickness dimension to electric machine casing 11 has strict size restrictions, when just the thickness sum of water channel inner housing 12 and water channel shell body 13 is limited in the very little scope, the thickness of water channel shell body 13 can't utilize and be wasted, and has therefore reduced radiating efficiency.
Summary of the invention
In order to overcome the defective of prior art, provide a kind of radiating efficiency high water cooling plant, the utility model discloses a kind of water cooling plant that is used for motor.
The utility model reaches goal of the invention by following technical solution:
A kind of water cooling plant that is used for motor, comprise the water channel inner housing, the water channel shell body, water channel and spiral heat dissipation rib, its structure is: the water channel inner housing is made of the end and the columniform stack shell of flange-type, be fixed with the cooling fin of spiral type on the stack shell outer wall, space between the cooling fin constitutes the water channel of spiral type, the water channel shell body is the cylinder that one the one end opening other end has inner flange shape end, cylinder bottom centre has a through hole, the external diameter of the internal diameter of water channel shell body cylinder and water channel inner housing cylinder equates, the equal in length of the degree of depth of water channel shell body cylinder and water channel inner housing cylinder, the diameter of water channel shell body cylinder bottom centre through hole and the internal diameter of water channel inner housing cylinder equate, the water channel shell body is enclosed within outside the water channel inner housing, one end of water channel shell body cylinder props up the end of the flange-type of water channel inner housing, one end of water channel inner housing cylinder props up the cylinder bottom of water channel shell body, a through hole is opened as water inlet in one end junction of water channel shell body and water channel, and a through hole is opened as delivery port in other end junction.
The described water cooling plant that is used for motor, its structure is: the water channel shell body is enclosed within outside the water channel inner housing, and the cooperation between them is an interference fit.
The described water cooling plant that is used for motor, its structure is: the water channel shell body is enclosed within outside the water channel inner housing, adopt between the end of one end of water channel shell body cylinder and the flange-type of water channel inner housing to be welded to connect, an end of water channel inner housing cylinder and the cylinder of water channel shell body bottom are adopted and are welded to connect.
The beneficial effects of the utility model are: because inside and outside water channel has been made into plug bush type by the enclosing cover formula, thereby the position of weld seam when having changed welding, make weld seam from side wall portion from the end-transfer water channel of water channel housing, so just improved the stock utilization of water channel shell end, can be applicable to the tighter occasion of motor case size restrictions, can under the situation that does not reduce heat dispersion, make full use of the electric machine casing end space, thereby guarantee under less space, to design the heat radiation water channel of satisfying the demand.
