[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] To facilitate the understanding of this embodiment, a highly efficient liquid cooling heat dissipation device disclosed in the embodiments of the present utility model will be introduced in detail first. Embodiment

[0026] As Figures 1 - 3 shown, a highly efficient liquid cooling heat dissipation device of the present application includes a liquid cooling plate base 100 and an upper cover plate 200 covering the liquid cooling plate base 100. The upper cover plate 200 is welded to the liquid cooling plate base 100 by friction stir welding, reducing or eliminating welding cracks and pores and improving the airtightness of the device. The liquid cooling plate base 100 has a first accommodation space 101 and a second accommodation space 102. A liquid cooling channel 103 for connecting the first accommodation space 101 and the second accommodation space 102 is provided between the first accommodation space 101 and the second accommodation space 102. A first flow dividing plate 104 is provided in the first accommodation space 101, and a second flow dividing plate 105 is provided in the second accommodation space 102. The first flow dividing plate 104 and the second flow dividing plate 105 are symmetrically arranged about the midline of the liquid cooling plate base 100 in the length direction. Since the liquid cooling plate base 100 has a first accommodation space 101 and a second accommodation space 102, a first flow dividing plate 104 and a second flow dividing plate 105 are respectively provided in the first accommodation space 101 and the second accommodation space 102, and the first flow dividing plate 104 and the second flow dividing plate 105 are symmetrically arranged about the midline of the liquid cooling plate base 100 in the length direction, so that the flow channels of the first accommodation space 101 and the second accommodation space 102 are kept consistent, better controlling the flow rate and velocity of the flow channels and improving the liquid cooling heat dissipation effect.

[0027] As Figure 4 shown, when the present application is implemented, the battery cell or other heat generating bodies are placed on the upper cover plate 200. When the heat generating bodies work, the present application can quickly absorb and take away the heat generated by them, ensuring the heat dissipation effect.

[0028] Specifically, a number of first diversion channels 1041 are arranged in parallel along the length direction of the first diversion plate 104, and a number of second diversion channels 1051 are arranged in parallel along the length direction of the second diversion plate 105; both ends of the first diversion plate 104 have two first inclined diversion surfaces 1042, and the two first inclined diversion surfaces 1042 are symmetrically arranged with respect to the midline of the first diversion plate 104 along the length direction; both ends of the second diversion plate 105 have two second inclined diversion surfaces 1052, and the two second inclined diversion surfaces 1052 are symmetrically arranged with respect to the midline of the second diversion plate 105 along the length direction. By adjusting the inclination angles at both ends of the first and second diversion plates, the overall uniformity and the flow rate of the liquid cooling medium are improved, and the liquid cooling and heat dissipation effect is further enhanced.

[0029] Specifically, one end of the liquid cooling plate seat 100 is provided with a first water nozzle 106 communicating with the first accommodation space 101, and one end of the liquid cooling plate seat 100 in the same direction as the first water nozzle 106 is provided with a second water nozzle 107 communicating with the second accommodation space 102. Since the first diversion plate 104 and the second diversion plate 105 are symmetrically arranged, the first water nozzle 106 and the second water nozzle 107 can not only be used as water outlets but also as water inlets, improving the versatility and practicality of the device.

[0030] In summary, through the above structural design, the present utility model solves the deficiencies in the prior art and has the characteristics of reasonable structure, good heat dissipation effect, and strong practicality.
