Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present disclosure, the technical scheme in the embodiment of the present disclosure is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole embodiments.
Based on the embodiment in the disclosure, it is all that those of ordinary skill in the art are obtained under the premise of creative work is not made
Other embodiment, belongs to the scope of disclosure protection.
In a first aspect, the utility model embodiment provides a kind of battery liquid cooling apparatus, as shown in Figures 1 to 3, the device includes
Liquid cooling plate 1 and the runner flow regulating part being arranged on the liquid cooling plate 1, wherein：
The liquid cooling plate 1 includes plate shell 14 and the cooling liquid flowing channel being arranged on inside plate shell 14；
The making material of the runner flow regulating part includes shape-memory material, for contacting battery 3 and basis
The surface temperature of contacted battery 3 adjusts the uninterrupted of the cooling liquid flowing channel.
It will be appreciated that because runner flow regulating part is made up of shape-memory material, it is according to temperature adjustment
The process of the uninterrupted of cooling liquid flowing channel is actually the deformation process of shape-memory material, and the deformation of shape-memory material is led
The uninterrupted of cooling liquid flowing channel is caused to change.
For example, the surface temperature of the battery 3 touched when runner flow regulating part is than relatively low, less than shape memory
During the deformation temperature of material, the deformation of shape-memory material causes the flow of cooling liquid flowing channel smaller, cooling effect now compared with
It is low.When the surface temperature for the battery 3 that runner flow regulating part is touched is increased above the deformation temperature of shape-memory material
When, the deformation of shape-memory material causes the flow of cooling liquid flowing channel to become big, and cooling effect now is improved.When through stronger cold
But after, the surface temperature for the battery 3 that runner flow regulating part is touched decreases below the deformation temperature of shape-memory material
When, the deformation of shape-memory material causes the flow of cooling liquid flowing channel to diminish, and intensity of cooling is in than relatively low state.
The battery liquid cooling apparatus that the utility model is provided includes runner flow regulating part, and the flow regulating part is by shape
Shape memory material is made, and the change of temperature can cause the deformation of runner flow regulating part, so as to cause the stream of cooling liquid flowing channel
The change of size is measured, the function that intensity of cooling is automatically adjusted is realized.Because the battery liquid cooling apparatus that the utility model is provided can
The surface temperature of the battery 3 touched according to runner flow regulating part automatically adjusts intensity of cooling, for different batteries 3,
The deformation quantity for the runner flow regulating part being in contact with it is different, so cooling capacity of the liquid cooling apparatus for different batteries 3
It is different, it is possible to achieve to the differential management of the battery 3 of different temperatures, so that the temperature difference of each battery 3 is controlled very
Small scope, improves the service efficiency of battery 3, extends the service life of battery 3.

The portion 22 of damming, is arranged in the cooling liquid flowing channel inside the plate shell 14, for according to the contact connected
The surface temperature for the battery 3 that portion 21 is contacted deforms upon to adjust the uninterrupted of the cooling liquid flowing channel.
For example, the surface temperature of the battery 3 touched when contact site 21 is than relatively low, less than the shape of shape-memory material
During temperature, portion 22 of damming, which is in, compares the state unfolded so that in cooling liquid flowing channel negotiable coolant section ratio
It is smaller, therefore the flow of cooling liquid flowing channel is smaller, intensity of cooling is than relatively low.When the surface for the battery 3 that contact site 21 is touched
Temperature is higher, higher than the deformation temperature of shape-memory material, and portion 22 of damming shrinks, so that negotiable in cooling liquid flowing channel
The section of coolant becomes big, and the flow of cooling liquid flowing channel becomes big, and intensity of cooling is improved.When after stronger cooling, contact site
21 surface temperatures of battery 3 reductions contacted, less than shape-memory material deformation temperature when, the deformation in portion 22 of damming recovers,
So that the flow of cooling liquid flowing channel diminishes, intensity of cooling is set to become again than relatively low state.
In the runner flow regulating part of said structure, being arranged on the contact site 21 outside plate shell 14 is used to contact battery
3, the temperature that the portion 22 of damming being arranged in the cooling liquid flowing channel of enclosure interior is sensed according to its contact site 21 connected is sent out
Raw deformation, to realize the regulation of the uninterrupted to the cooling liquid flowing channel.The runner flow regulating part structure letter of the structure
Single, easily realization.
In the specific implementation, the cooling liquid flowing channel inside liquid cooling plate 1 can use multiple structural forms, corresponding portion of damming
22 set-up mode also can be different.As shown in Figures 1 to 3, a kind of alternative construction form of wherein cooling liquid flowing channel is：The cooling
Liquid runner includes master and enters circulation road 11, main return flow line 12 and connect the master to enter circulation road 11 and the main return flow line 12
Multiple bypass passages 13.For the cooling liquid flowing channel of this structure, the portion of damming 22 can be arranged at least one branch road and led to
In road 13.
In the cooling liquid flowing channel of said structure, coolant is entered circulation road 11 from master and flowed into, after bypass passage 13, from
Draw main return flow line 12.Because the portion of damming 22 is arranged at least one bypass passage 13, thus can realize to this at least one
The flow of individual bypass passage 13 is adjusted.
In the cooling liquid flowing channel of said structure, the bypass passage 13 can have multiple structural forms realization, for example, join
Fig. 2 is examined, bypass passage 13 is by being arranged on the shape of multiple ribs 15 that the master enters between circulation road 11 and the main return flow line 12
Into, certainly can also using other structures form realize.
In the specific implementation, above-mentioned shape-memory material can use marmem, it would however also be possible to employ thermotropic
Shape-memory polymer, certainly can also using other can because of temperature deformation material, this utility model is not limited
It is fixed.
It is that above-mentioned plate shell 14 can be made of a variety of making materials, preferably be led to make it have in specific implementation
It is hot, metal, such as such as copper, it would however also be possible to employ alloy, aluminium alloy can be selected.
Second aspect, the utility model also provides a kind of battery system, including multiple batteries 3, in addition to any of the above-described electricity
Pond liquid cooling apparatus, the battery liquid cooling apparatus contacts setting with each battery 3.
It will be appreciated that because the battery system that second aspect is provided includes the battery fluid cold charge of first aspect offer
Put, explanation, illustration about content.The contents such as optional embodiment, beneficial effect may be referred to first aspect offer
Appropriate section in battery liquid cooling apparatus, will not be repeated here.
In summary：
Battery liquid cooling apparatus and battery system that the utility model embodiment is provided, including runner flow regulating part, should
