Embodiment
Preferred embodiment provided by the invention is illustrated with reference to the accompanying drawings.
Fig. 1 to Fig. 5, it is a kind of preferred embodiment of the liquid cooling plate of internal shunt provided by the invention.Such as Fig. 1 to Fig. 5
Shown, the liquid cooling plate includes plate main body 10 and preceding plug 20 for the front end of sealing plate main body 10 and for sealing plate main body 10
The rear plug 30 of rear end, plate main body 10 is interior to be provided with several fluid passages 11, and the front end of plate main body 10, which forms to be provided with, supplies preceding plug
The open front 12 of 20 insertions, the rear end of plate main body 10 are provided with the after-opening 13 for the insertion of rear plug 30, and so preceding plug 20 inserts
In open front 12, rear plug 30 is inserted in after-opening 13, and coolant flows in fluid passage 11.Plate main body 10 uses aluminium section bar
Straight forming.
As shown in Figures 2 to 4, branch chamber 22 is provided with the preceding plug 20, preceding plug 20 is provided with and connected with branch chamber 22
Liquid inlet joint 21, the side wall of branch chamber 22 is provided with several, and corresponding with the inlet side of fluid passage 11 respectively be used for will be from feed liquor
Joint 21 branches to the diffluence pass 23 of fluid passage 11 into the coolant of branch chamber 22, and the sectional area of diffluence pass 23 is less than liquid
The sectional area of passage 11, so when preceding plug 20 inserts open front 11, after coolant is from liquid inlet joint 21 into branch chamber 22,
Because the sectional area of diffluence pass 23 is less than the sectional area of fluid passage 11, coolant can not fully enter neighbouring liquid inlet joint rapidly
21 fluid passage 11, coolant are assembled in branch chamber 22, and pressure increase, coolant uniform divided flows enter other each fluid passages
11, so that have coolant entrance in each fluid passage 11, improve radiating efficiency.
The side of plug 20 before liquid inlet joint 21 is arranged on, liquid inlet joint 21 are integrally machined out with preceding plug 20 using CNC
Come, without welding, branch chamber 22 and diffluence pass 23 on preceding plug 20 are to be integrally machined shaping；Before the insertion of preceding plug 20
Be open 12 when, preceding plug 20 and coldplate main body 10 are connected using friction welding mode.
As shown in Fig. 2, Fig. 3 and Fig. 5, mixed flow chamber 32 is provided with the rear plug 30, rear plug 30 is provided with and mixed flow chamber 32
Connection goes out liquid joint 31, the side wall of mixed flow chamber 32 be provided with several respectively the water side with multiple fluid passages 11 to application
Imported in the coolant that will go out end outflow from fluid passage 11 after mixed flow chamber 32 mixes again from the liquid outlet for going out liquid joint 31 and flowing out
33, the sectional area of liquid outlet 33 is less than the sectional area of fluid passage 11, so few from the cooling liquid measure that fluid passage 11 flows out, cold
But liquid can be full of whole fluid passage 11, strengthen radiating effect, improve radiating efficiency.
Go out the side that liquid joint 31 is arranged on rear plug 30, go out liquid joint 31 and be integrally machined out with rear plug 30 using CNC
Come, without welding, mixed flow chamber 32 and mixed flow chamber 32 on rear plug 30 are to be integrally machined shaping；After the insertion of rear plug 30
Be open 13 when, rear plug 30 and plate main body 10 are connected using friction welding mode.
It is worth noting that, liquid inlet joint 21 and go out liquid joint 31 all in space on side, has been saved, so to new energy
When the battery of source automobile cools down, one piece of liquid cooling plate can cool down two battery modules simultaneously, improve cooling effectiveness.
In summary, technical scheme can realize foregoing invention purpose, and the knot of the present invention with sufficiently effective
Structure and the principle of work and power have all sufficiently been verified in embodiment, can reach the effect of expected and purpose, without departing substantially from this
On the premise of the principle and essence of invention, various changes or modifications can be made to the embodiment of invention.Therefore, the present invention includes
All be previously mentioned in patent claim in the range of all replacement contents, it is any to be made in scope of the present invention patent
Equivalence changes, all belong to this case application the scope of the claims within.
