Specific embodiment
The preferred embodiment of the utility model is described in detail with reference to the accompanying drawing, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, to make the protection scope of the utility model apparent clear
Define.
Attached drawing 1 to 7 is please referred to, the utility model embodiment includes:
A kind of New energy automobile motor channel structure of high efficiency and heat radiation, including being arranged in water channel cavity: divide water muscle, every
Water muscle and the muscle that blocks water.Water outlet 2 and water inlet 1 are set on water channel cavity, and cooling water enters from water inlet 1, then goes out the mouth of a river 2
Discharge.But will appear the dead angle of many places in water flow passage, i.e. cooling water although it is possible to reach, but water can not circulate or
It is difficult to the position circulated.As shown in figure 3, cooling water flows to water outlet 2 along nearest path from water inlet 1 when without confining tendon, remaining
Part is dead angle, and cooling water cannot flow through.
The raised confining tendon 3 from the upper/lower terminal face of water channel cavity, as shown in figure 4, when an only confining tendon 3, water
Road cavity is a big cavity, and cooling water is from water inlet 1 to water outlet, and internal there are the dead angles that a large amount of cooling waters do not circulate.
Therefore, a plurality of confining tendon 3 is set, one is provided between two ends of water flow passage vertically through water channel cavity
Confining tendon, which interrupts water channel cavity；Remaining confining tendon is arranged in water flow passage other positions, remaining confining tendon
It is fixed on water channel cavity by single end, free end on confining tendon 3 and is spaced 35mm between the inner edge of water flow passage.Upside
Confining tendon 3 and the confining tendon 3 of downside successively uniform intervals arrange, water channel cavity has been separated into a sine wave by confining tendon 3
Shape water flow passage, and water outlet 2 and water inlet 1 are separately positioned on two end points of water flow passage.Water flow passage is along upper and lower two sides
To reciprocating rotating, perforative confining tendon make water flow passage can only one-way flow, remaining confining tendon 3 separates water channel cavity, is formed bent
The path spacing of detour is rolled over, flow path is increased, reduces the blind area that cooling water cannot reach, it is ensured that motor internal heat dissipating is uniform.
As shown in figure 5, when being uniformly distributed confining tendon, water flow passage forms the path of tortuous detour, but water flow passage corner there are still compared with
The dead angle of large area.
So being provided with a point of water muscle 4 in every vertical flow channel section in water flow passage, the setting of water muscle 4 is divided to flow
On the middle line of road section, flow channel section is divided water muscle to be divided into left and right two parts.Divide water muscle 4 that water flow passage is divided into double channel structures,
As shown in fig. 6, flow path is divided into two, flow path is further increased, eliminates dead angle, but be difficult to ensure two sides water flow
It is uniform.
It is additionally provided with the muscle 5 that blocks water of protrusion at the crossover position of two connected flow channel sections, single water channel is flowed through to come
Water slightly stop, so that flowing water is equably flowed to the path for dividing 4 two sides of water muscle.As illustrated in fig. 1 and 2, it blocks water and muscle 5 while also increasing
The length of water channel extends residence time of the water in water channel, optimizes refrigerating function.
For this design feature of further explanation, admittedly the structure size of part is enclosed, as shown in fig. 7, water flow passage is outer
The size of space between edge and base mating surface is 20mm, and the height for the muscle protrusion that blocks water is 12mm.Divide water muscle, confining tendon and blocks water
The end point of muscle is rounded corner setting.
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
Using equivalent structure or equivalent flow shift made by the utility model description, it is applied directly or indirectly in other phases
The technical field of pass, is also included in the patent protection scope of the utility model.
