Be equipped with first cavity in the plate body 1, first parting bead 5 has set gradually under to from last in the first cavity, second parting bead 6 and third parting bead 7, first parting bead 5, the length at second parting bead 6 and third parting bead 7 both ends increases in proper order, and then at first parting bead 5, form step-like diffluence area 21 between the lateral wall of second parting bead 6 and third parting bead 7 and plate body 1, through step-like diffluence area 21, in the inflow below runner that the coolant liquid can be even, the coolant liquid in the runner of both sides mixes in the step-like diffluence area at both ends about the first parting bead simultaneously, the temperature uniformity of liquid-cooled board can be improved, and then the life of extension battery module and power battery's continuation of the journey mileage. The stepped flow dividing region 21 is a virtual region formed between the dividing bar and the side wall of the plate body 1, and the design is already the prior art and is not described herein.
Example 2
Referring to fig. 2, compared with embodiment 1, the difference of this embodiment is that the plate body 1 further includes a second cavity, the first cavity and the second cavity are separated by a reinforcing rib 12, and a first channel 13 is opened in the middle of the reinforcing rib 12 and is used for communicating the first cavity and the second cavity. The setting of second cavity can enlarge the cooling area of liquid cold plate, is suitable for bigger battery module and battery, and the coolant liquid in the first cavity takes place to mix in first passageway 13 for the samming performance of liquid cold plate obtains promoting, is favorable to prolonging the life and the continuation of the journey mileage of battery module.
The fourth division bar 14, the fifth division bar 15 and the sixth division bar 16 are sequentially arranged in the second cavity from top to bottom, the lengths of the two ends of the fourth division bar 14, the fifth division bar 15 and the sixth division bar 16 are sequentially increased to form a step flow distribution area, so that cooling liquid uniformly enters a flow channel below after being mixed again, and the temperature uniformity of the liquid cooling plate is improved. The middle part of first parting bead 5, third parting bead 7, fourth parting bead 14 and sixth parting bead 16 all is provided with opening 2, and feed liquor pipe 3 and drain pipe 4 are corresponding with opening 2 on first parting bead 5 and the sixth parting bead 16 respectively, form the coolant liquid passageway of cross, can reduce the inside flow resistance of liquid cooling board, and the coolant liquid can be more quick flows in and flows out, improves the cooling effect. Because the openings 2 on the third division bar 7 and the fourth division bar 14 are arranged at the respective middle parts, and the first channel 13 is arranged at the middle part of the reinforcing rib 12, the cooling liquid in the first cavity can smoothly enter the second cavity, and is firstly distributed in the flow channels at the upper side and the lower side of the fourth division bar 14, and then flows to the step-shaped flow distribution areas at the left side and the right side. The openings 2 in the third and fourth division bars 7, 14 correspond to the design of the first channel 13, which is advantageous for the uniform distribution of the cooling liquid in the liquid cooling plate.
According to different parameters of the length and the width of the flow channel of the liquid cooling plate, the width of the opening 2 on the fourth division bar 14 and the width of the first channel 13 can be adjusted adaptively, generally, the width of the opening 2 on the fourth division bar 14 is not larger than the width of the first channel 13, otherwise, more cooling liquid flowing out of the first channel 13 enters the flow channel at the lower side of the fourth division bar 14, so that the cooling liquid at the upper side and the lower side of the fourth division bar 14 is not distributed uniformly, and the cooling effect of the liquid cooling plate is influenced; similarly, if the size of the opening 2 is too small, the coolant distribution on the upper and lower sides of the fourth division bar 14 is also uneven. The ratio of the width of the first channel 13 to the width of the opening 2 in the fourth dividing strip 14 ranges from 1: 1-0.5, and the width of the opening 2 and the width of the first channel 3 can be adjusted to adapt to the length and the channel width parameters of different liquid cooling plates, so that the cooling liquid can uniformly flow into the channels on the upper and lower sides of the fourth division bar 14.
Example 3
Referring to fig. 3, the present embodiment is different from embodiment 2 in that the plate body 1 is a profile plate, and both ends of the plate body 1 are closed by plugs 17. Compared with the liquid cooling plate manufactured by the stamping and welding processes, the liquid cooling plate has the advantages that the processing cost of the section plate is low, the structural strength is high, the two ends of the section plate are generally open, and the section plate needs to be closed by using the plugs 17.
The middle part of the upper surface of the plate body 1 is provided with a mounting port 18, the mounting port 18 is sealed by a support plate 19, and the liquid inlet pipe 3 and the liquid outlet pipe 4 are arranged on the support plate 19. The installation opening 18 is formed for processing the opening 2 on the partition strip inside the plate body 1, and the support plate 19 is assembled on the plate body 1 at the back, so the liquid inlet pipe 3 and the liquid outlet pipe 4 can be installed on the support plate 19 in advance, and then the support plate 19 is welded at the installation opening 18, thereby improving the assembly efficiency of the liquid cooling plate.
