The chip is closely attached to the plane of the toothed aluminum profile, and the heat is transferred to the air through the toothed aluminum sheet. However, in the closed and compact space of the PACK box, this heat dissipation method and installation space can no longer meet the requirements.

DETAILED DESCRIPTION OF THE INVENTION

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] In the description of the present invention, unless otherwise clearly defined and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0024] Refer to Figures 1 - 6 , a battery and electronic control integrated liquid-cooled plate structure, including a liquid-cooled plate main manifold 1, a heat dissipation plate 2, and side plates 4. A number of spliced liquid-cooled plates 3 are connected to one side of the liquid-cooled plate main manifold 1, and the liquid outlet end of the other side of the liquid-cooled plate 3 is connected to a return manifold 5; the heat dissipation plate 2 is vertically arranged above the liquid-cooled plate main manifold 1, and the heat dissipation plate 2 is used to increase the heat dissipation area; the side plates 4 are connected to both ends of the liquid-cooled plate main manifold 1 and the return manifold 5, and the inner side of the side plates 4 is clamped with the liquid-cooled plate 3. The heat dissipation plate 2 improves the heat exchange efficiency. The liquid-cooled plate adopts a brazing connection process to closely combine the liquid-cooled plate main manifold 1 and the heat dissipation plate 2 to ensure good heat conduction performance. The brazing connection process is used to maintain the flatness of the heat dissipation plate 2 and prevent deformation.

[0025] Refer to Figure 3 , Figure 4 , fixing holes 102 are provided at both ends of the liquid-cooled plate main manifold 1. An inlet liquid groove 104 is opened on one side of the liquid-cooled plate main manifold 1. A number of liquid outlet holes are opened inside the inlet liquid groove 104. A first reinforcing rib 103 is arranged on one side of the liquid-cooled plate main manifold 1. The heat dissipation plate 2 adopts a lightweight design and selects high-strength lightweight materials to reduce the overall weight. The overall length of the heat dissipation plate 2 is equal to that of the liquid-cooled plate main manifold 1; a number of liquid-cooling channels are arranged inside the liquid-cooled plate 3, and the liquid-cooling channels are communicated with the inlet liquid groove 104 and the return manifold 5 at both ends. The coolant enters from the liquid-cooled plate main manifold 1, enters the liquid-cooling channels inside the liquid-cooled plate 3 through the inlet liquid groove 104, and flows out through the return manifold 5, taking away the heat of the heat source on the liquid-cooled plate 3 to achieve the effect of liquid-cooled heat dissipation.

[0026] Refer to Figures 3 - 6, at both ends of the heat dissipation plate 2, there are second reinforcing ribs 201 connected at the corners, and several mounting holes 202 are respectively connected above and below the middle of the heat dissipation plate 2. The vertically arranged heat dissipation plates 2 can more effectively guide the heat to dissipate upward and reduce heat accumulation; at the splicing part of the liquid cooling plate 3, there is an L-shaped splicing part 301, and the shapes and sizes of the splicing parts 301 match. The L-shaped splicing part 301 is convenient for direct overlapping. On the inner side of the side plate 4, there is a splicing groove 401, and the splicing groove 401 is clamped with the outer side of the liquid cooling plate 3, and the two sides of the liquid cooling plate 3 are clamped through the splicing grooves 401 on both sides to form an integral structure.

[0027] Working principle: The heat dissipation plate 2 adopts a layout perpendicular to the main manifold 1 of the liquid cooling plate, effectively utilizing the vertical space, avoiding the height occupation of the space by the traditional parallel layout, making the overall structure more compact. Moreover, the vertically arranged heat dissipation plates 2 can more effectively guide the heat to dissipate upward and reduce heat accumulation. Then, the second reinforcing ribs 201 are connected to the inside of the heat dissipation plate 2 to achieve lightweight while ensuring the strength and stability of the heat dissipation plate 2 and reducing the overall weight. Through the brazing process, the temperature, pressure, and time parameters during the brazing process are strictly controlled to form a good bonding interface between the main manifold 1 of the liquid cooling plate and the heat dissipation plate 2. After brazing, the flatness of the heat dissipation plate 2 is ensured. The coolant enters through the main manifold 1 of the liquid cooling plate, then flows through the liquid inlet groove 104 and into the liquid cooling channels inside the liquid cooling plate 3 through the liquid outlet holes, and then flows into the return manifold 5 to discharge and complete the heat cycle absorption.

[0028] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent replacements or changes, and all should be covered within the protection scope of the present utility model.
