[0030] Embodiment

[0031] As Figures 1-6As shown in the figure, this embodiment discloses an aluminum-plastic composite liquid cooling plate, which includes a pipe body 1, a first connector 2, a second connector 3 and a reinforcing plate 4. A liquid cooling channel for the flow of liquid cooling medium is provided inside the pipe body 1. A first channel 21 and a second channel 22 for the inflow of liquid cooling medium are provided inside the first connector 2. A third channel 31 for the outflow of liquid cooling medium is provided inside the second connector 3. One end of the first connector 2 and one end of the second connector 3 are respectively provided with a first opening 23 and a second opening 32. The first connector 2 is provided at one end of the pipe body 1 through the first opening 23, connecting the first channel 21 and the second channel 22 with the liquid cooling channel. The second connector 3 is provided at the other end of the pipe body 1 through the second opening 32, connecting the third channel 31 with the liquid cooling channel. Reinforcing plates 4 are provided at the openings of the first opening 23 and the second opening 32. The reinforcing plates 4 are used to seal the connection between the first opening 23 and the pipe body 1 or the connection between the second opening 32 and the pipe body 1. By providing the first connector 2 and the second connector 3 and respectively arranging them at both ends of the pipe body 1, the liquid cooling medium converges from the first channel 21 and the second channel 22 of the first connector 2 to the first opening 23, and flows into the liquid cooling channel through the first opening 23. The liquid cooling medium flows along the liquid cooling channel and exchanges heat with the external battery at the same time, thereby reducing the heat of the external battery. Then it flows out of the liquid cooling channel through the second opening 32 and out of the liquid cooling plate through the third channel 31 to complete the heat exchange of the liquid cooling medium. By providing the reinforcing plates 4, the connection strength between the first connector 2 and the second connector 3 and the pipe body 1 is increased, thereby improving the mechanical strength of the liquid cooling plate and prolonging the service life of the liquid cooling plate.

[0032] Further, the first connector 2 is further provided with two water inlets 24. One water inlet 24 is connected to the first opening 23 through the first channel 21, and the other water inlet 24 is connected to the first opening 23 through the second channel 22. The second connector 3 is further provided with a water outlet 33. The water outlet 33 is connected to the second opening 32 through the third channel 31. As Figure 5 shown, by symmetrically arranging two water inlets 24, the liquid cooling medium enters the first channel 21 and the second channel 23 respectively through the two water inlets 24, and finally converges into the liquid cooling channel for heat exchange. As Figure 6 shown, by providing one water outlet, the liquid cooling medium enters the third channel 31 through the liquid cooling channel and finally leaves the liquid cooling plate through the water outlet 33 to complete the heat exchange. Through the above settings, the inflow of the liquid cooling medium can be increased, the outflow of the liquid cooling medium can be reduced, and the flow time of the liquid cooling medium in the liquid cooling channel can be prolonged, so that the liquid cooling effect of the liquid cooling plate is better.

[0033] Further, a first limiting groove 25 for fixing the pipe body 1 is provided in the first opening 23, and the inner wall of the first limiting groove 25 abuts against the outer wall of one end of the pipe body 1; a second limiting groove 34 for fixing the pipe body 1 is provided in the second opening 32, and the inner wall of the second limiting groove 34 abuts against the outer wall of the other end of the pipe body 1. By providing the first limiting groove 25 and the second limiting groove 34, the first connector 2 and the second connector 3 can be accurately installed at both ends of the pipe body 1, ensuring that both ends of the pipe body 1 are symmetrically arranged and improving the liquid cooling effect of the liquid cooling plate.

[0034] Further, limiting bumps 5 are provided in both the first limiting groove 25 and the second limiting groove 34. The number of the limiting bumps 5 is four. Two of the limiting bumps 5 are symmetrically arranged in the first limiting groove 25, and two of the limiting bumps 5 are symmetrically arranged in the second limiting groove 34; the limiting bumps 5 are used to abut against the end of the pipe body 1. By providing the limiting bumps 5 in the first limiting groove 25 and the second limiting groove 34, it is ensured that the first connector 2 and the second connector 3 will not be displaced, and further improves the symmetrical arrangement of the first connector 2 and the second connector 3 at both ends of the pipe body 1.

[0035] Further, the areas of the two reinforcing plates 4 are respectively adapted to the openings of the first opening 23 and the second opening 32. The two reinforcing plates 4 are respectively pressed on the openings of the first opening 23 and the second opening 32; the reinforcing plate 4 is also provided with a through hole 41. One end of the pipe body 1 passes through the through hole 41 of one reinforcing plate 4 and is welded to the first connector 2, and the other end of the pipe body 1 passes through the through hole 41 of the other reinforcing plate 4 and is welded to the second connector 3. The cross-sectional area of the through hole 41 is the same as the cross-sectional area of the two ends of the pipe body 1. During actual installation, first use an adhesive to bond the two reinforcing plates 4 to the openings of the first opening 23 and the second opening 32 respectively, then pass the two ends of the pipe body 1 through the through holes 41 respectively, and are respectively arranged in the first limiting groove 25 and the second limiting groove 34, and use welding to connect the first connector 2 and the second connector 3 to the pipe body 1, and finally complete the installation of the liquid cooling plate.

[0036] Further, the first connector 2 and the second connector 3 are both provided with an installation hole 6 and a fixing hole 7; the installation hole 6 is used to connect with an external liquid pump, and the fixing hole 7 is used to connect with an external battery. By providing the installation hole 6, the liquid cooling plate can be connected to an external liquid pump, thereby improving the liquid cooling effect of the liquid cooling plate; by providing the fixing hole 7, the liquid cooling plate can be connected to an external battery, thereby preventing the liquid cooling plate from being displaced relative to the external battery.

[0037] Furthermore, both the first connector 2 and the second connector 3 are made of resin, and both the tube body 1 and the reinforcing plate 4 are made of aluminum alloy. Further still, both the first connector 2 and the second connector 3 are made of one of PBT, PA66, and PPA. PBT, PA66, and PPA are high and low temperature resistant resins. The first connector 2 and the second connector 3 are both formed by integral injection molding, which can save production costs. Using different materials for the first connector 2 and the second connector 3 and the tube body 1 and the reinforcing plate 4 can solve the problem of deformation of the wall of the tube body 1 caused by connection between components.
