Description
Technical Field
The invention relates to the technical field of three-way cooling water pipes, in particular to a three-way cooling water pipe of a motor stator cooling water jacket.
Background
Wind power generation is a clean renewable energy source, and due to good environmental and economic benefits, is receiving more and more attention from countries around the world. With the development of wind power generators from 1.5MW, 2MW, 3MW, 6MW, 7.6MW, 10MW, 12MW to high-power and ultra-high-power wind power, the heat dissipation requirements on the generator body are also higher and higher.
At present, the cooling mode of the motor mainly adopts technologies such as natural air cooling, forced ventilation, air-water cooling, air-air cooling and the like, wherein the air-water cooling technology is researched by persons in the field due to unique advantages, a stator cooling water jacket is a core cooling part of the motor, the stator cooling water jacket is generally sleeved on the outer wall of a stator core in an interference manner, the stator core is cooled by means of flowing of cooling liquid in the stator cooling water jacket, and the arrangement and the structure of a water channel of the stator cooling water jacket have important influence on the pressure drop and the heat exchange performance of the cooling liquid. At present, the common water channel shapes comprise a Z-shaped water channel and a spiral water channel, the flow resistance of the Z-shaped water channel is large, a large water pump is needed for providing power, and therefore the spiral water channel is mostly adopted at present. The spiral water channel has various types, has the common advantage of small flow resistance, and has the defects that the coverage rate of the circulation area of the cooling liquid on the surface of the iron core is less than 100%, a cooling dead zone exists, and the processing technology requirement is higher, so that a parallel spiral water jacket provided with two cooling branches, two cooling liquid outlets 2 and two cooling liquid inlets 1 shown in fig. 1 appears, as described in a patent with the patent number of 201821331428.4 and the patent name of a motor stator cooling water jacket, the motor stator cooling water jacket in the patent achieves the motor cooling effect, and the cooling effect of the spiral water jacket is greatly improved compared with that of a common spiral water jacket. Because an electronic cooling water jacket of a motor (the cooling water jacket of the motor stator mentioned here and in the following text are all the cooling water jackets of the motor stator mentioned in patent No. 201821331428.4) needs to be matched with a radiator for use, in order to ensure that a water channel can work normally, a three-way cooling water pipe needs to be adopted for respectively inputting and shunting cooling liquid. However, the three-way cooling water pipe adopted in the current market is mainly T-shaped and herringbone, if the three-way cooling water pipe is applied to the motor stator cooling water jacket, the water resistance is larger, the diversion pipeline of the common water pipe and the input pipeline form the same angle, and after the diversion direction of the water channel of each diversion pipeline is determined, the angle is not changed any more, the pipeline cannot ensure that the water channel normally completes the cooling work, and the huge and economic waste of the motor structure is easily caused.
Disclosure of Invention
The invention aims to provide a three-way cooling water pipe of a motor stator cooling water jacket, which can be matched with the motor stator cooling water jacket in the background technology.
The invention is realized by adopting the following technical scheme:
the three-way cooling water pipe of the motor stator cooling water jacket comprises an inlet main pipe or an outlet main pipe and two inlet shunt pipes or two outlet shunt pipes, wherein one end of the inlet main pipe or the outlet main pipe is respectively and naturally extended (the natural extension refers to that the extending direction is smaller than the deviation angle of the main pipe, namely the deviation angle is smaller than 5 degrees), and is matched with two cooling liquid inlets or two cooling liquid outlets of the motor stator cooling water jacket (the two cooling liquid inlets of the double-helix parallel motor stator cooling water jacket are respectively positioned at two sides of a baffle, the two cooling liquid outlets are respectively positioned at two ends of a corresponding cooling channel of an outer ring, and the phase matching refers to that the positions and the extending direction of the two shunt pipes are respectively matched with the two cooling liquid inlets or the two cooling liquid outlets of the motor stator cooling water jacket).
When the two inlet shunt tubes are matched with two cooling liquid inlets of the motor stator cooling water jacket, the two inlet shunt tubes and the inlet header pipe can be collectively called as a three-way cooling water pipe used for a cooling liquid inlet, and cooling liquid enters from the inlet header pipe of the three-way cooling water pipe and then enters the motor stator cooling water jacket through the two inlet shunt tubes; when the two outlet shunt pipes are matched with two cooling liquid outlets of the motor stator cooling water jacket, the two outlet shunt pipes and the outlet header pipe can be collectively called as a three-way cooling water pipe for the cooling liquid outlet, and the cooling liquid flows out from the two outlet shunt pipes and then is converged into the outlet header pipe.
The beneficial effects produced by the invention are as follows: the three-way cooling water pipe breaks through the problem that the traditional three-way cooling water pipe is changed into a structure with natural extension, namely a structure with a small deviation angle from a large deviation angle of a common flow dividing pipe and a common header pipe, and the resistance is reduced.
