[0018] In order to better understand the content of the present application, the present application will be described in detail in conjunction with the embodiments. It should be understood that the embodiments are only used to explain and not limit the present application.

[0019] As shown in Figures 1-3 The present embodiment provides a new energy battery water cooling plate, which comprises a shell 1, a flow channel cavity 2 is formed in the shell 1, two partition plate assemblies 3 are spaced apart along the width direction in the flow channel cavity 2, the spacing between the two partition plate assemblies 3 is 0.5mm, the partition plate assembly 3 comprises a plurality of flow guide partition plates 31 spaced apart along the width direction, the spacing between the two adjacent flow guide partition plates 31 in the partition plate assembly 3 is 6mm, the cooling liquid flow channel 21 is formed between the two adjacent flow guide partition plates 31, and the adjacent cooling liquid flow channels 21 are connected end to end, so that the cooling liquid can flow through each cooling liquid flow channel 21 in turn in the flow channel cavity 2, thereby better ensuring the heat absorption of the cooling liquid to the new energy battery, thereby improving the cooling efficiency of the new energy battery.

[0020] Further, the plurality of flow guide partition plates 31 are connected to both ends of the height direction of the flow channel cavity 2, the flow channel cavity 2 is cut by a parallel face parallel to one end face of the length direction of the shell 1 to form a cross-sectional face, on the cross-sectional face, the flow guide partition plate 31 is arranged in a sinusoidal curve, and the sinusoidal curves formed by the flow guide partition plates 31 included in the two partition plate assemblies 3 are opposite, wherein the amplitude of the sinusoidal curve is 1mm, and the period is 3mm.

[0021] Specifically, by setting the flow guide partition plate 31 as a sine curve, the flow guide partition plate 31 can correspondingly elongate when the water pressure in the shell 1 is large and the flow channel cavity 2 deforms and expands, and timely contract when the water pressure decreases, so that the flow guide partition plate 31 can be stably connected with the shell 1 when responding to water pressure fluctuations, thereby preferably reducing the risk of fatigue fracture of the flow guide partition plate 31 and improving the service life of the new energy battery water cooling plate.

[0022] It can be understood that the shell 1 and the flow guide partition plate 31 are both made of aluminum alloy material with good ductility, such as 1100 aluminum alloy, 6061 aluminum alloy, etc.

[0023] The thickness of the shell 1 is 0.4mm, and the thickness of the flow guide partition plate 31 is 0.3mm, and the thickness of the flow guide partition plate 31 is less than that of the shell 1, so that the flow guide partition plate 31 has better elasticity and lighter weight.

[0024] The shell 1 is formed with a water inlet hole 4 and a water outlet hole 5 on both sides in the width direction, the water inlet hole 4 is used for accessing external cooling liquid, and the water outlet hole 5 is used for outputting cooling liquid.

[0025] Working principle:

[0026] The cooling liquid is pumped from the heat exchanger to the water inlet hole 4 of the water cooling plate through a centrifugal pump, the cooling liquid enters the flow channel cavity 2 from the water inlet hole 4, and then flows through each cooling liquid flow channel 21 in turn, and finally flows out of the flow channel cavity 2 from the water outlet hole 5 and returns to the heat exchanger, the water cooling plate is installed in the new energy battery box, and the heat in the new energy battery box is absorbed by the flowing cooling liquid, thereby reducing the temperature of the new energy battery.

[0027] When the temperature in the new energy battery box is high, the flow of the cooling liquid is large, so the pressure borne by the shell 1 is large and is prone to deformation, and the flow guide partition plate 31 in a sine curve has good elasticity, i.e. deformation recovery capability, which can preferably maintain the structure of the cooling liquid flow channel 21.

[0028] It is easy to understand that those skilled in the art can obtain other embodiments by combining, splitting, recombining, etc. on the basis of one or more embodiments provided in the present application, and these embodiments do not exceed the protection scope of the present application.

[0029] The above describes the present application and its embodiments in a schematic manner, and the description is not restrictive, and the embodiments shown are only part of the embodiments of the present application, and the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this, without departing from the creative purpose of the present application, they can design similar structural modes and embodiments without creativity, which should all belong to the protection scope of the present application.
