Description
Technical field: the present invention relates to a kind of platypelloid type permanent-magnet linear water-cooled machine cooling structure.
Background technology: magneto need realize that the volume with minimum reaches the purpose of maximum thrust; Can increase the current density of motor through the mode that adds cooling, thereby realize this purpose, the permanent-magnet linear water-cooled machine mainly contains two kinds of forms at present; A kind of is that additional cooling jacket dispels the heat indirectly outside iron core; This mode increased motor volume and and thermal source between heat to transmit the number of plies more, thermal resistance is bigger, volume is big and radiating effect is bad.Another kind is in the iron core yoke, to inlay cooling water pipe; This type of cooling is also more direct than first kind of less heat radiation of mode motor volume, but same problem is far away from thermal source, and thermal resistance is bigger; And can't fit tightly between smooth cooling water pipe of external diameter and the iron core; Most of is that line contacts, and area of dissipation is little, influences radiating effect.
Summary of the invention: the objective of the invention is to propose a kind of simple, convenient, effective platypelloid type permanent-magnet linear water-cooled machine cooling structure, to realize the maximization of permanent-magnetism linear motor unit volume thrust.The technical scheme that the present invention adopts is: a kind of platypelloid type permanent-magnet linear water-cooled machine cooling structure, and the elementary of motor is mover, secondary is stator; Secondary is the polylith splicing, and secondary is the oblique utmost point mode of permanent magnet, i.e. angle of permanent magnet and motor movement axis inclination; The elementary integral body of motor is with the embedding of epoxy heat-conducting glue, and elementary iron core adopts the narrow tooth mode of sipes, and promptly the ratio of the iron core groove width and the facewidth is greater than 1; At slot for winding bottom land and trough rim punishment cloth open slot, be coated with in the open slot and put highly heat-conductive material and embed cooling water pipe, the cooling water pipe flattening fits tightly with open slot and is equal with the open slot notch; Elementary iron core yoke portion is uniformly distributed with the straight mouthful groove of round bottom, is coated with in straight mouthful of groove groove of round bottom and puts highly heat-conductive material, straight mouthful groove of round bottom and cooling water pipe interference fit; Cooling water pipe guarantees closely to contact with the straight mouthful groove of round bottom after being pressed into the straight mouthful groove of round bottom, and cooling water pipe is the non-smooth copper cooling menifold of external diameter, and the water inlet of cooling water pipe and delivery port are at elementary iron core one end; The elementary iron core yoke portion T type groove that evenly distributes; T type groove is embedded in T type mounting bar, opens screwed hole on the T type mounting bar, and elementary winding is a fractional slot winding.
The transfer route of heat is as shown in Figure 5, and the thermal source of motor is a winding, the thermaltransmission mode of winding heat be mainly through cooling water circulation heat is taken away and shell and outside air between heat exchange.Begin to launch water cooling during the motor operation, because the heat of the winding of motor is higher than the heat of elementary iron core, so let cooling circulating water get into by the water inlet of cooling water pipe; Flow through the earlier cooling water pipe of slot for winding bottom land and trough rim; Cooling circulating water carries out heat exchange through cooling water pipe and highly heat-conductive material and winding, and the heat of winding is taken away, the cooling water pipe of the elementary iron core yoke portion that flows through again; Cooling circulating water carries out heat exchange through cooling water pipe and highly heat-conductive material and elementary iron core; The heat of elementary iron core is taken away, and simultaneously, winding arrives shell through highly heat-conductive material with heat transferred; Elementary iron core arrives shell through highly heat-conductive material with heat transferred, carries out heat exchange through the shell and the external world.
Technique effect of the present invention is:
1. placing cooling water pipe at slot for winding can effectively dispel the heat to winding; Simultaneously increased one deck radiating tube at the iron core yoke portion cooling water pipe of arranging; Cooling water pipe is that copper cooling menifold can effectively increase area of dissipation; Inlay to be coated with in the groove of cooling water pipe and put high heat conduction based material and can effectively fill increase area of dissipation, good cooling results the slit of not contact.
2. place the volume that cooler can not increase motor in core interior, at the bottom of slot for winding, inlay cooling water pipe and can not influence magnetic circuit, therefore can not influence motor performance with magnetic field weakness fluting such as trough rim.
3. cooling water pipe is double-deck layout in iron core, and promptly slot for winding bottom land and trough rim place are cooled to one deck, and iron core yoke portion is cooled to one deck, and this structure is convenient to realize a side Inlet and outlet water, is convenient to wiring, the convenient use.
4. slot for winding bottom land, trough rim and iron core yoke portion slot simultaneously and inlay the non-smooth copper cooling menifold of external diameter, and are coated with at cooling menifold and iron core face and put highly heat-conductive material, can increase area of dissipation, improve radiating effect.
