Embodiment
The problem of existing for prior art, inventor it has been investigated that, the input port of cooling duct and defeated
Region of the outlet near the both sides of partitions, this partitions between input port and delivery outlet is formed
Slough.
During cooling agent is circulated, due to the reason of partitions, the low temperature cold flowed into from input port
But agent can be flowed to the direction of delivery outlet, and only a small amount of cryogenic coolant flow to partitions and input port it
Between cooling duct region so that when the cooling agent in the cooling duct region between partitions and input port is long
Between in not flow regime.
Correspondingly, the cryogenic coolant from input port, which is flowed through, is changed into high temperature coolant behind cooling duct, high
Warm cooling agent flows directly into delivery outlet and exported, and only a small amount of high temperature coolant flows to partitions and output
Region between mouthful so that the cooling agent in region is in for a long time between partitions and delivery outlet does not flow shape
State.Therefore, the region near the partitions between input port and delivery outlet forms slough.
Because the cooling agent in region between partitions and delivery outlet keeps the condition of high temperature for a long time, or even because of heat
The cooling agent heating for causing region between input port and partitions is exchanged, causes the cooling agent of slough long-term
High temperature is kept, causes motor hot-spot, electric energy loss increase, motor working efficiency declines.
Accordingly, inventor proposes the problem of a kind of new motor cooling scheme is to reduce motor hot-spot.
It is understandable to enable the above objects, features and advantages of the present invention to become apparent, below in conjunction with the accompanying drawings to this
The specific embodiment of invention is described in detail.
Reference picture 1, Fig. 1 shows a kind of motor 1 for electric automobile, and motor 1 can connect speed change
There is provided driving force for device input shaft.Motor 1 includes housing 2 and the cooling duct 3 in housing 2, cold
But passage 3 is around the axis of housing 2, and cooling agent can absorb electricity in the internal circulation flow of cooling duct 3
The heat that machine work is produced.Partitions 4 is provided with cooling duct 3, partitions 4 is in housing 2
Axis is two subchannels, respectively the first subchannel 31 and second so that cooling duct 3 to be separated vertically
Subchannel 32.With reference to reference picture 2, partitions 4 has the first subchannel 31 of connection and the second subchannel 32
Interface channel 30.Two subchannels have input port 310 and delivery outlet 320 respectively, and such as the first son is logical
Road 31 has input port 310, and the second subchannel 32 has delivery outlet 320, input port 310 and delivery outlet
320 with interface channel 30 it is circumferentially spaced set.
The flow direction of cooling agent is：The first subchannel 31 is flowed into from input port 310, two-way is then split into,
Respectively along around two circumferential opposite direction A of housing 21And A2Flowed towards interface channel 30；
After interface channel 30 is converged to, respectively along two opposite direction A1And A2Flow into the second subchannel 32；
Afterwards respectively along two opposite direction A1And A2Delivery outlet 320 is flowed to, delivery outlet 320 is being converged to
After export.Cooling agent absorbs the heat that motor work is produced in flow process, realizes the mesh of electric motor temperature reduction
's.
Input port 310 and delivery outlet 320 are circumferentially spaced with interface channel 30 so that input port 310
With interface channel 30 along housing 2 axially without overlapping region, delivery outlet 320 and interface channel 30 are along shell
Body 2 is axially without overlapping region.This ensures that the cooling agent inputted from input port 310 can be logical in the first son
Two opposite direction A in road 31 circumferentially1And A2Flowing, and finally converge to interface channel 30.Phase
Ying Di, two opposite directions that the cooling agent for inputting the second subchannel 32 from interface channel 30 can be circumferentially
A1And A2Delivery outlet 320 is converged to export.
If input port 310 has overlapping region vertically with interface channel 30, inputted from input port 310
Cooling agent can largely flow to interface channel 30, and only a small amount of cooling can be circumferentially to 310 liang of input port
Side is flowed, and causes the cooling agent in the first subchannel 31 to form slough in not flow regime for a long time.
Similarly, if delivery outlet 320 has overlapping region, the second subchannel 32 vertically with interface channel 30
It is interior to form slough.
Utilize the motor cooling scheme of the technical program, the first subchannel 31, the second subchannel 32 and connection
Cooling agent in passage 30 is in constant flow state, will not form slough.Therefore whole cooling is logical
Cooling agent in road 3 is in continuous flow regime, reduces the probability to form slough.This can eliminate electricity
The problem of 1 hot-spot of machine, reduce electric energy loss, the operating efficiency of lifting motor 1.
Reference picture 1, housing 2 includes water jacket 20 and the motor housing 21 being enclosed on outside water jacket 20, and cooling is logical
Road formation is between water jacket 20 and motor housing 21.The wherein outer peripheral face of water jacket 20 is formed with annular groove 22,
Motor housing 21 seals annular groove 22 to form cooling duct 3.
Reference picture 2, Fig. 2 is the stereogram of water jacket 20 in housing 2, input port 310 and delivery outlet 320
On the same straight line parallel to the axis of housing 2, and circumferentially it is separated by 180 ° with interface channel 30,
Input port 310 and delivery outlet 320 are radially corresponding along housing 2 with interface channel 30.So, first
In subchannel 31, the cooling agent inputted from input port 310 is along two opposite direction A1And A2To interface channel
30 length of flow is essentially identical, and the cooling effect of two parts cooling agent can be utilized effectively, and this can
The cooling effectiveness of overall lifting cooling agent.It is not when input port 310 is circumferentially separated by with interface channel 30
At 180 °, a shorter path of the cooling agent from input port 310 circumferentially flows to interface channel 30, the portion
Point cooling agent length of flow is shorter, and effective cool time is short, and its refrigerating function utilization rate is low.
On the other hand, in the first subchannel 31, from input port 310 along two opposite direction A1And A2
The cooling agent dose difference for flowing to interface channel 30 is little, and this two-way cooling agent is to motor 1 (reference picture 1)
Cooling effect approach, the various pieces of motor 1 be equalized cooling.
Correspondingly, in the second subchannel 32, the cooling agent flowed into from interface channel 30 is along two-phase negative side
To A1And A2Length of flow and dosage to delivery outlet 320 are substantially the same, along this two opposite direction A1
And A2The cooling agent of flowing is approached to the cooling effect of motor 1.Therefore, the various pieces of motor 1 can obtain
More cool down in a balanced way.
Reference picture 2- Fig. 4, the axial width H of the first subchannel 31 where input port 310 is set1Circumferentially-
It is gradually reduced from input port 31 to interface channel 30 (Fig. 3 is not shown).Heat fluxIt is with heat exchange
There is following proportionate relationship between the temperature difference (Δ T) between number (h), cooling agent and housing 2：
And h ∝ v (v is coolant flow speed), heat flux is for can be used for characterizing cooling agent from the absorption heat of housing 2
Ability.
With the axial width H of the first subchannel 311Circumferentially from input port 310 to interface channel 30 by
Decrescence small, coolant flow speed v gradually increases, and coefficient of heat transfer h gradually increases.As cooling agent is being flowed over
Absorbed heat in journey from housing 2, temperature difference T is gradually reduced.But because h also gradually increases, this can compensate temperature
Poor Δ T reduces to heat fluxInfluence, keep heat fluxSubstantially constant, this makes the first subchannel 31
The ability that the cooling agent inside circumferentially flowed absorbs heat in flow process from housing 2 is more consistent, and heat absorption is held
Continuous property is good, the more effective cooling effect using cooling agent.
The axial width H of first subchannel 311Two opposite direction A circumferentially1And A2From input port
310 are gradually reduced to interface channel 30, from input port 310 along two opposite direction A1And A2To connection
The cooling agent that passage 30 flows is respectively provided with constant heat fluxWhen input port 310 and interface channel 30
When being circumferentially separated by 180 °, in the first subchannel 31, from 310 points of input port, two-way flows to interface channel
30 cooling agent heat fluxRelatively, it is more balanced to the cooling effect of motor 1 (reference picture 1).
The axial width H of second subchannel 32 where delivery outlet 320 is set2Circumferentially from interface channel 30
(Fig. 4 is not shown) is gradually reduced to delivery outlet 320, refer to above-mentioned on cold in the first subchannel 31
But the heat flux of agentThe temperature difference (Δ T) between the coefficient of heat transfer (h), cooling agent and housing 2
Proportionate relationship, and the coefficient of heat transfer (h) and coolant flow speed proportionate relationship, flowed from interface channel 30
To the cooling agent heat flux constant of delivery outlet 320, the cooling circumferentially flowed in the second subchannel 32
Agent consistent heat absorption capacity during constant flow, heat absorption continuation is good.
The axial width H of second subchannel 322Two opposite direction A circumferentially1And A2From interface channel
30 are disposed as being gradually reduced to delivery outlet 20, and delivery outlet 320 is flowed to from 30 points of two-way of interface channel
Cooling agent is respectively provided with constant heat fluxCircumferentially it is separated by 180 ° in delivery outlet 320 and interface channel 30
When, the second subchannel 32 is from interface channel 30 along two opposite direction A1And A2Flow to delivery outlet 320
Cooling agent heat flux is more balanced to the cooling effect of motor 1 than more consistent.
The axial width H of first subchannel 31 can be set1Two opposite direction A circumferentially1And A2
It is gradually reduced from input port 310 to interface channel 30, and the axial width H of the second subchannel 322Along this
Two opposite direction A1And A2It is gradually reduced from interface channel 30 to delivery outlet 320, this can realize whole
Cooling agent heat flux in individual cooling duct 3Reach unanimity, heat absorption continuation is good.
The axial width H of cooling duct 3 can be circumferentially invariable, and the axial width of partitions 4
It is circumferentially constant.So, the axial width H of the first subchannel 311Circumferentially from input port 310 to even
While connection road 30 is gradually reduced, the axial width H of the second subchannel 322Circumferentially from interface channel
30 are gradually reduced to delivery outlet 320.Now the axis of the axis of partitions 4 and cooling duct 3 it
Between have not be 0 angle, partitions 4 for ellipse.
As a kind of variation, partitions can include the body that is coaxially disposed with cooling duct and to first
Prominent projection or cooling duct have to first positioned at the side of the first subchannel side in subchannel
Prominent projection in subchannel, can set axial width of the projection along body axial direction circumferentially from input port
Gradually increase to interface channel, to realize the axial width of the first subchannel circumferentially from input port to connection
Passage is gradually reduced.
As another variation, partitions can include the body that is coaxially disposed with cooling duct and to the
Prominent projection or cooling duct are located at the side of the second subchannel side and had to the in two subchannels
Prominent projection in two subchannels, can set axial width of the projection along body axial direction circumferentially from connection
Passage gradually increases to delivery outlet, to realize the axial width of the second subchannel circumferentially from input port to even
Road is connected to be gradually reduced.
Compared to above-mentioned variation scheme, the formation process of cooling duct 3 is fairly simple in the present embodiment,
Feasibility is higher.
Reference picture 3, when the axial width H of cooling duct 3 is constant, the first son where input port 310
Axial width H of the passage 31 in the position of input port 3101More than the axial width H of cooling duct 3 half.
The axial width H of first subchannel 311From reduction trend of the input port 310 to interface channel 30 circumferentially
Can be with obvious, the slope of change is larger, and this can provide larger regulation space, to mend as far as possible
Temperature difference T is repaid to reduce to heat fluxInfluence, maintain heat fluxIt is constant.
Further, reference picture 4, set axial width H of each subchannel in the position of interface channel 303
And H4The axial width H of cooling duct 30 half can be equal to, each subchannel is attached in interface channel 30
Near axial width H3And H4It is substantially equal to the axial width H of cooling duct 3 half.Now, cool down
When agent is flowed through interface channel 30 from the first subchannel 31 to the second subchannel 32, in the first subchannel 31
Interior A in the first direction1The cooling agent of flowing flows into after interface channel 30 A in a second direction2Flow into the second son
A in a second direction in passage 32, the first subchannel 312The cooling agent of flowing flows into edge after interface channel 30
First direction A1The second subchannel 32 is flowed into, in the both sides of interface channel 30 circumferentially, is led to from the first son
The flow velocity and flow that road 31 flows into the cooling agent of the second subchannel 32 are basically identical, it is to avoid certain side occur
Coolant flow is smaller and causes the problem of motor 1 (reference picture 1) Local cooling effect is not good.
Reference picture 2- Fig. 4, is circumferentially separated by input port 310 and delivery outlet 320 with interface channel 30
At 180 °, the first subchannel 31 and the second subchannel 32 are set on input port 310, delivery outlet 320
Plane with the place of interface channel 30 is symmetrical.The axial width H of first subchannel 311From input port 310
To the two opposite direction A of interface channel 30 (Fig. 3 is not shown) circumferentially1And A2The slope phase of reduction
Together, from input port 310 along two opposite direction A in such first subchannel 311And A2Flow to interface channel
30 coolant flow, flow velocity v and heat fluxAll same.
Correspondingly, the axial width H of the subchannel 32 of the second subchannel 322From interface channel 30 to output
320 two opposite direction A circumferentially of mouth1And A2The slope of reduction is identical, such second subchannel 32
In from interface channel 30 along two opposite direction A1And A2Flow to coolant flow, the flow velocity of delivery outlet 320
V and heat fluxAll same.So, first subchannel 31 is in input port 310 where coordinating input port 310
The axial width H of position1More than the axial width H of cooling duct 3 half, and each subchannel is in connection
The axial width H of the position of passage 303And H4The axial width H of cooling duct 30 half can be equal to,
So, heat flux of the cooling agent flowed in whole cooling duct 3 in regionalCan have height
Uniformity is spent, this can preferably solve the problem of motor Local cooling effect is not good.
As a kind of variation, the axial width edge week of the axial width of the first subchannel and the second subchannel
To can be with constant.Under constant and non-constant two kinds of situations, the first son where can setting input port is logical
The axial width of second subchannel where the axial width in road is more than delivery outlet.So, inputted from input port
Effective cooled region of cryogenic coolant in first subchannel is larger, and it is logical to flow into the second son from interface channel
High temperature coolant flow velocity v in road is fast, heat fluxLoss is compensated, and is kept to a certain extent
The cooling effect of cooling agent in two subchannels.
Interface channel 30 is to form the breach in partitions 4 in reference picture 2 and Fig. 4, the technical program.
As an improvement, interface channel can be axially extending bore or axial pass trough.
