Description

Technical Field

[0001] The utility model relates to the technical field of new energy vehicle battery cooling, in particular to a water cooling plate profile for new energy vehicle batteries. Background Art

[0002] New energy vehicle batteries typically dissipate heat through water cooling. The structure involves multiple batteries arranged side by side, separated by water cooling plates. These plates are equipped with water troughs through which cooling water flows, achieving the desired cooling effect.

[0003] The battery and water-cooling plate are typically enclosed in a sealed battery pack to ensure a stable mounting structure. Because the water tank on the water-cooling plate is typically shallow, the cooling water flow is limited. This can lead to delayed cooling, especially when the vehicle is performing kinetic energy recovery and simultaneously using multiple electrical devices. The heat dissipated by the battery is high. Utility Model Content

[0004] In order to solve the technical problems in the background technology, the utility model discloses a water cooling plate profile for new energy vehicle batteries.

[0005] The utility model provides a water cooling plate profile for new energy vehicle batteries, comprising a body, wherein a placement cavity is provided in the body for placing a battery pack;

[0006] A left cooling water cavity and a right cooling water cavity are arranged at intervals on both sides of the placement cavity, and cooling water flows in the left cooling water cavity and the right cooling water cavity.

[0007] The main body provides additional cooling for the battery pack to ensure that the battery remains stable and does not overheat. The main body can also cool the battery installation chamber, so that the vehicle chassis below the battery installation chamber and the bottom plate above the battery installation chamber can be cooled, thereby keeping the overall temperature of the vehicle stable.

[0008] Since the hot air heated by the battery flows upward, in order to reduce the space occupied by the main body and save costs, the further design is: the end face of the main body is trapezoidal, with its long side facing upward; the left cooling water cavity and the right cooling water cavity are both triangular, and their horizontal lengths decrease from top to bottom.

[0009] Since the hot air heated by the battery flows upward, in order to improve the heat dissipation effect, a further design is that upper cooling water chambers are arranged at intervals on the upper side of the placement cavity.

[0010] Providing a separate water source or water inlet connector to the upper cooling water chamber would complicate the structure. Therefore, a further improvement is to connect one end of the upper cooling water chamber to the left cooling water chamber and the other end to the right cooling water chamber. With this arrangement, the cooling water in the upper cooling water chamber comes from both the left and right cooling water chambers.

[0011] Since the space in the battery installation room is limited, if a rectangular cooling water chamber is set on the top plate of the cavity, the strength of the top plate will be reduced. Based on this, further improvements are: the upper cooling water chamber includes a plurality of evenly distributed and spaced oblong holes, and the length direction of the oblong holes is arranged horizontally; the oblong holes are connected through the middle water channel; the left cooling water chamber and its adjacent oblong holes are connected through the left water channel; the right cooling water chamber and its adjacent oblong holes are connected through the right water channel; the widths of the middle water channel, the left water channel and the right water channel are all smaller than the width of the oblong holes.

[0012] To further enhance cooling, the upper and lower end surfaces of the placement cavity are both wavy, creating multiple air passages between the upper and lower end surfaces of the placement cavity and the battery pack, allowing hot air to be exhausted.

[0013] In order to improve the installation stability of the battery pack, a further design is that a raised positioning column is also provided on the lower end surface of the placement cavity for clamping the battery pack.

[0014] In order to improve the stability of the installation structure of the body, a further design is that a recessed slot is provided on the upper end surface of the body for positioning the body during installation. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0020] like Figure 1 As shown, the utility model discloses a water-cooling plate profile for new energy vehicle batteries, comprising a main body 1 with a trapezoidal end face, the long side of which is located on the upper side, the short side is located on the lower side, and the long side and the short side are both horizontal.

[0021] The main body 1 is bilaterally symmetrical, with a rectangular cavity 2 in the center for accommodating the battery pack. A raised positioning post 10 is also provided on the lower end of cavity 2 to engage the battery pack and enhance its positional stability. A left cooling water chamber 3 and a right cooling water chamber 4 are spaced apart on either side of cavity 2, through which cooling water flows.

[0022] The upper end surface of the body 1 is provided with a recessed slot 11 for mounting and positioning the body 1 .

[0023] Since the hot air flows upward, the left cooling water chamber 3 and the right cooling water chamber 4 are both inverted triangles, and their horizontal lengths decrease from top to bottom.

[0024] Since hot air flows upward, in order to improve the heat dissipation effect, upper cooling water chambers arranged at intervals are further provided on the upper side of the placement chamber 2.

[0025] The upper cooling water chamber includes a plurality of evenly spaced, spaced oblong holes 6, with the lengthwise direction of the oblong holes 6 arranged horizontally. The oblong holes 6 are connected to each other via a central water channel 7. The left cooling water chamber 3 is connected to its adjacent oblong hole 6 via a left water channel 8. The right cooling water chamber 4 is connected to its adjacent oblong hole 6 via a right water channel 9. The widths of the central water channel 7, the left water channel 8, and the right water channel 9 are all less than the width of the oblong hole 6. In this embodiment, the widths of the central water channel 7, the left water channel 8, and the right water channel 9 are each one-quarter the width of the oblong hole 6. This arrangement maintains the structural strength and stability of the top plate of the placement chamber 2. Furthermore, the cooling water in the upper cooling water chamber is derived from the left cooling water chamber 3 and the right cooling water chamber 4, simplifying the water supply structure.

[0026] like Figure 2 As shown, the upper and lower end surfaces of the placement cavity 2 are both wavy. Multiple air passages can be formed between the upper and lower end surfaces of the placement cavity 2 and the battery pack, and hot air can be discharged outward along the air passages, which can further improve the cooling effect of the battery.

[0027] The main body 1 provides additional cooling for the battery pack to ensure that the battery remains stable and does not overheat. The main body 1 can also cool the battery installation chamber, thereby cooling the vehicle chassis below the battery installation chamber and the bottom plate above the battery installation chamber, thereby keeping the overall vehicle temperature stable.

[0028] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
