The uniform cooling of multiple components, is particularly suitable for the battery pack of electric car in domain, makes the consistency of battery pack, safety, makes
It is significantly improved with the service life.
Specifically, there are many technical solutions for the set-up mode of flow passage structure 1.
One of technical solution are as follows: the water inlet flow channel 11 is identical with 12 shape of outlet passage, and disposed proximate.
It is identical that water inlet flow channel 11 and outlet passage 12 can be set to shape, for example is all linear, arc line shaped, simple fold-line-shaped
Deng, mutually close to setting, so while cooling, water inlet flow channel 11 and the common realization cooling effect of outlet passage 12, and due to

Scheme, do not limit to it is identical with shape be arranged side by side, the design of runner can be adjusted according to service condition, make its arrangement more
Adduction reason, is preferably applied in certain special environment, such as the bending concavo-convex portion pair that length is longer and close to setting
The region for needing emphasis to radiate should be set, can targetedly emphasis be radiated, better effect.
Based on the above-mentioned technical proposal, the flow passage structure 1 includes at least two cooled regions 13, each cooled region
13 include at least one concavo-convex portion.In order to guarantee that overall cooling capacity is almost the same in each cooled region 13, each cooled region
The number of 13 concavo-convex portions for including should be consistent.The cooled region 13 of flow passage structure 1, corresponding multiple components for needing cooling,
It is cooled down together in each cooled region 13 by water inlet flow channel 11 and outlet passage 12, and due to 11 He of water inlet flow channel
The connection of 12 one end of outlet passage, the other end sequentially pass through each cooled region 13, the feed water flow in cooled region 13 same in this way
Road 11 and outlet passage 12 flow direction on the contrary, water temperature height interlock, by control water inlet flow channel 11 and outlet passage stream 12 shape,
The parameters such as size can accomplish that the cooling capacity in each cooled region 13 is of substantially equal, and cooled region 13 each in this way can be same
When the almost the same uniform cooling of temperature is carried out to multiple components, be not in that inhomogeneous cooling is even and cause to generate asking for the temperature difference

The length of road 11 and outlet passage 12 is almost the same, and the water inlet flow channel 11 of low temperature and higher temperature goes out in such cooled region 13
Although water flow passage 12 has temperature difference, complementation is formed, and in different cooled regions 13, high temperature mutually balances each other, and realizes
The overall cooling capacity of each cooled region 13 is identical.Alternatively, it is also possible to pass through the radial dimension to water inlet flow channel 11 and outlet passage 12
And the adjustment of length, it can not be identical, but by the connection between being calculated accordingly, control at radial dimension and length
In suitable parameter, so that cooling capacity can also be consistent, for example low 11 radial dimension of water inlet flow channel of temperature can be smaller,
But length is longer, and high 12 radial dimension of outlet conduit of temperature can be larger, but length is shorter or anti-mistake
Come, the purpose that whole cooling capacity is of substantially equal, and realization uniformly cools down can control by experimental data calculating.

Temperature (being calculated with the temperature averages of a segment pipe) be respectively t1 ', t2 ', t3 ', t4 ', t1 ' > t2 ' > t3 ' >
T4 ', due to the connected relation of water inlet flow channel 11 and 12 one end of outlet passage, t4 < t4 ', so whole temperature level relationship is
T1 ' > t2 ' > t3 ' > t4 ' > t4 > t3 > t2 > t1, and corresponding water inlet flow channel 11 in four cooled regions 13 from left to right
Temperature with outlet passage 12 is respectively t1 and t1 ', t2 and t2 ', t3 and t3 ', t4 and t4 ', it can be seen that, the minimum t1 of temperature
Cooperate the highest t1 ' of temperature, the high t2 of the next to the lowest t2 cooperation temperature control two of temperature, and so on, in each cooled region 13
