Embodiment
Describe the invention in detail below with reference to the accompanying drawings.
The structure of the invention as Figure 1-4, including mainboard 1 and it is some in layered arrangement in the side of mainboard 1
Cooling layer 2, the mainboard 1 is provided with fluid inlet channel 11 and fluid outlet channels 12, and having in the cooling layer 2 can be for stream
The hollow channel of body circulation, the hollow channel has to be connected with the fluid inlet channel 11 and fluid outlet channels 12 respectively
Hollow entrance and hollow outlet, the hollow channel of the cooling layer 2 is communicated in the fluid inlet channel 11 in parallel
Between fluid outlet channels 12.
The stratiform parallel-connection structure of the cooling layer 2 is advantageous to the uniform temperature of each battery core, avoids the part of the several battery cores in center
Temperature is too high.The distance between described cooling layer 2 can be adjusted and design as needed, ensure to put between every two layers of cooling layer 2
A module block is put, cooling layer 2 and the battery core of centre is directly contacted.Cooling fluid flows in cooling layer 2 so that cold
But fluid expands the area of contact and heat exchange, compared to traditional tubular conduit or structure in state is sprawled in cooling layer 2
It is more beneficial for the progress of heat exchange.
Wherein, the hollow channel in the cooling layer 2 is in roundabout bending structure, is advantageous to extend the flowing road of cooling fluid
Journey (flow circuits as shown in Fig. 2 dotted arrows), while be advantageous to flowing of the fluid in cooling layer 2 and sprawl, it can make in addition
Obtain cooling fluid to flow through near the lug of battery, ensure the uniform temperature of whole battery core.Or the hollow channel in the cooling layer 2
Can also be in the forge piece of step type structure (flow circuits as shown in Fig. 5,6 dotted arrows) that both sides are straight-through, central parallel is in parallel, it is described
Forge piece of step type structure center partial width in parallel increases step by step, to increase the flow resistance that fluid flows directly out, the forge piece of step type structure
Central part in parallel can be with rectangular (such as Fig. 5) or arc (such as Fig. 6).
Further, the roundabout bending structure of hollow channel or forge piece of step type structure are hollow in cooling layer 2 in the cooling layer 2
Cavity stops and formed via the enclosed construction interval being staggered；The enclosed construction can be up and down the two of connection cooling layer 2
The vertically arranged thin-walled of individual aspect, the two aspect relevant positions up and down that can also preferably connect cooling layer 2 are opposed, inwardly directed
The blockade line 21 (such as Fig. 4) for being recessed and being combined together to form；The enclosed construction is preferably set to 1-5.Further, institute
The hollow entrance and hollow outlet of hollow channel are stated respectively positioned at its roundabout bending structure or the both sides of forge piece of step type structure.
Wherein, the cooling layer 2 is made of material that is flexible, can bearing certain pressure, such as PP-T20, to protect
The intensity of product is demonstrate,proved, ensures that coolant is convenient while reducing the risk of leakage and flows.
Wherein, the gross thickness of cooling layer 2 is within 2mm, within preferably 1mm, ensure product space availability ratio and
Cooling fluid is sprawled.
Wherein, the hollow outlet of hollow channel is more than hollow entrance in the cooling layer 2, can reduce system flow resistance.
Wherein, the cooling layer 2 is connected by one section of arc structure 22 with mainboard 1 respectively, and arcuation is provided with arc structure 22
Passage so that hollow channel is led to by the fluid inlet channel 11 and fluid issuing of the arcuation passage and mainboard 1 respectively in cooling layer 2
Road 12 connects.The arc structure 22 belongs to flexible connection mode, while cooling layer 2 is overall relatively thin so that cooling layer 2 is easily rolled over
Rise, facilitate the installation of module and to ensure that module installs rear bending part unstressed.
Wherein, the fluid inlet channel 11 and fluid outlet channels 12 are respectively the hollow channel being arranged in mainboard 1,
It is respectively preferably the passage extended straight.Because the fluid inlet channel 11 and fluid outlet channels 12 are via cooling layer 2
Hollow channel connection, the two can not be connected on mainboard 1, thus the mainboard 1 can be simultaneously lead to provided with fluid intake
One entire plate in road 11 and fluid outlet channels 12, or be respectively equipped with fluid inlet channel 11 and fluid outlet channels 12
Two pieces of different plate bodys.
The preferred embodiment of the invention is the foregoing is only, is not intended to limit the invention creation, it is all at this
Within the spirit and principle of innovation and creation, any modification, equivalent substitution and improvements made etc., the invention should be included in
