Description

Technical Field

[0001] The utility model relates to the technical field of automobile water cooling plates, in particular to a water cooling structure for automobiles. Background Art

[0002] An automobile water cooling plate usually refers to a part of the water cooling system in an automobile, which is used to help dissipate heat and reduce the engine temperature. In an electric vehicle, the water cooling plate may be a part of the cooling system of the battery pack or the motor. The water cooling plate is applied in new energy vehicles (including pure electric vehicles and plug-in hybrid vehicles) and range-extended electric vehicles. Specifically, the water cooling plate is a metal plate with flow channels inside, and a liquid coolant (such as water or a water-based mixture) circulates through these flow channels to absorb and carry away the heat generated by the battery or the motor. This way can more effectively control the temperature and help improve the overall performance and endurance of the electric vehicle;

[0003] However, the existing water cooling plates only utilize one side, and the other side is designed as a protrusion for forming flow channels, which results in a large sacrifice. For example, in automobile applications, in-vehicle computer chips are extremely prone to heat generation and may cause the system to freeze. If the in-vehicle computer chips can be installed on the other side of the water cooling plate, not only can the additional heat dissipation structure required for installing the chips be reduced, but also a more efficient heat dissipation effect than the existing chip heat dissipation structure can be provided by using the water cooling method. Therefore, we propose a new water cooling structure for automobiles. Summary of the Utility Model

[0004] The purpose of this part is to outline some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments.

[0023] In order to make the above-mentioned objects, features and advantages of the present utility model more obvious and understandable, the following will describe the detailed implementation manners of the present utility model in conjunction with the accompanying drawings of the specification.

[0024] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0025] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present utility model. The "in one embodiment" that appears in different places in this specification does not all refer to the same embodiment, nor is it an independent or alternative embodiment that excludes other embodiments.

[0026] Embodiment

[0027] Refer to Figures 1 to 5, which is an embodiment of the present utility model. This embodiment provides a water-cooling structure for an automobile, namely a water-cooling plate 100. The back of the water-cooling plate 100 is a box body. A part of the front of the water-cooling plate 100 is recessed towards the box body, so that a part of the back of the water-cooling plate 100 protrudes from the box body. The front of the water-cooling plate 100 is recessed into a water-cooling structure 102, which is connected to a water circulation structure 103 provided on the water-cooling plate 100. The back of the water-cooling structure 102 is connected to a chip structure;

[0028] Specifically, by stamping, the back of the water-cooling plate 100 can be made into a box body. Then, by reverse stamping a smaller area from the front of the water-cooling plate 100, a structure with depressions and protrusions on both sides of the water-cooling plate as shown in Figure 1 is formed. The groove water-cooling structure 102 stamped on the front is what we call the water-cooling structure 102. The difference between this so-called water-cooling structure 102 and a common water-cooling plate is that its back is a flat surface, while the traditional one has raised channels. This allows a chip to be installed on its back for heat dissipation of the chip. By connecting the water-cooling structure 102 and the water circulation structure 103 to form a closed loop, the flowing medium can dissipate heat from the automobile battery and in-vehicle chips simultaneously;

[0029] Illustrate the structure in which the water-cooling structure 102 and the water circulation structure 103 are connected to form a closed loop;

[0030] 1. Water-cooling structure: This part is usually a special design inside or on the surface of the water-cooling plate, such as grooves, pipes, etc., which are used to guide the cooling medium (such as water or a special coolant) to flow through the area that needs to be cooled. 2. Water circulation structure: This includes a pump and a pipe system, which are used to drive the cooling medium to circulate in the water-cooling structure. The pump is responsible for providing sufficient power to overcome the resistance of the water flow, ensuring that the cooling medium can be evenly distributed and effectively take away heat. 3. Radiator: After the cooling medium flows out of the water-cooling plate, it will enter the radiator, where it exchanges heat with air to reduce the temperature. The radiator is usually equipped with a fan to increase air flow and improve the heat dissipation efficiency. 4. Inlet / outlet pipe interface: It is used to connect the pipes of the pump and the radiator, ensuring that the cooling medium can circulate between the water-cooling structure, the pump, and the radiator. The working principle is briefly described as follows: Medium circulation: When the pump is started, it will push the cooling medium to enter the water-cooling structure from the inlet pipe interface of the water-cooling plate. When the cooling medium flows in the water-cooling structure, it will absorb the heat generated by the chip or other heating elements. Heat exchange: The heated cooling medium then flows to the radiator, where it cools down by exchanging heat with air. Recycling: The cooled medium returns to the water-cooling plate from the radiator and is sent into the water-cooling structure by the pump again to complete a cycle process. This process is repeated continuously to achieve continuous and effective heat dissipation.

[0031] Exemplarily, the box body is a concave back surface 101, a clamping block 107 is provided in the concave back surface 101, and a wire groove 106 for fixing the wire harness is provided in the concave back surface 101 to cooperate with the chip. The clamping block 107 is provided for the installation of the water cooling plate 100 and the packaging board, and as Figures 1 - 2 it can be seen that many of its structures are also corresponding to the relevant packaging board settings. The wire groove 106 facilitates wiring and fixing between the PCB board and the chip;

[0032] Exemplarily, the water cooling structure 102 includes a water storage tank 102a, an intermediate partition 102b and partition strips 102c. The chip is arranged on the back surface of the water storage tank 102a, and the depth of the water storage tank 102a is less than the depth of the concave back surface 101. An installation bump 105a for installing the chip is provided on the back surface of the water storage tank 102a. The water storage tank 102a is divided into two parts by the intermediate partition 102b, and a plurality of partition strips 102c are provided in each part. The water storage tank 102a is separated into a plurality of flow channels 102a-1 between adjacent partition strips 102c. The water circulation structure 103 includes a water inlet pipe 103a and a water outlet pipe 103b. The water inlet pipe 103a and the water outlet pipe 103b are respectively arranged at both ends of the intermediate partition 102b and are communicated with the water storage tank 102a. By installing the intermediate partition 102b in the water storage tank 102a, the water storage tank 102a is further divided into longer and curved flow channels, and then a plurality of narrower flows are formed by arranging the partition strips 102c between the two parts. This not only forms the flow channels of the traditional water cooling plate, but also solves the drawback that at least one side of the water storage tank 102a has "protrusions of the flow channels";

[0033] Exemplarily, the partition strip 102c is composed of alternately intersecting protrusions 102c-1 and depressions 102c-2. First round corners 102c-3 and second round corners 102c-4 are sequentially provided at the top of the partition strip 102c and at the intersection with the water storage tank 102a. By setting the partition strip 102c to a curved shape, longer flow channels 102a-1 can be formed in the limited water storage tank 102a, and the curved shape can form a certain resistance to the medium, prolonging the heat exchange efficiency of the medium. The smooth round chamfers are beneficial to the uniform flow of the medium, enabling the water cooling plate 100 to better play a uniform heat exchange effect;

[0034] Exemplarily, a cover plate installation groove 104 for installing a sealing plate is provided on the front surface of the water cooling plate 100 at the water cooling structure 102. A positioning post 104a is provided on the cover plate installation groove 104. Positioning holes 104b are provided around the outside of the front surface of the water cooling plate 100 at the periphery of the water cooling structure 102. The depth of the cover plate installation groove 104 should be the same as the thickness of the sealing plate. The two form a flat cooling area on the front surface of the water cooling plate 100 to dissipate heat from the battery, which has the same function as the traditional water cooling plate.

[0035] Importantly, it should be noted that the construction and arrangement of the present application shown in multiple different exemplary embodiments are merely illustrative. Although only a few embodiments are described in detail in this disclosure, those who refer to this disclosure should easily understand that many modifications are possible without materially departing from the novel teachings and advantages of the subject matter described in this application (for example, the dimensions, scales, structures, shapes and proportions of various elements, and parameter values (such as temperature, pressure, etc.), installation arrangements, use of materials, color, orientation changes, etc.). For example, an element shown as integrally formed may be composed of multiple parts or elements, the position of the element may be inverted or otherwise changed, and the nature, number or position of discrete elements may be altered or changed. Therefore, all such modifications are intended to be included within the scope of the present utility model.
