Abstract
Description
Technical Field
[0001] This utility model relates to the field of domain controller heat dissipation technology, and in particular to a heat dissipation structure, controller module and automobile. Background Technology
[0002] With the increasing prevalence of autonomous driving, the number of autonomous driving controllers is also growing. Furthermore, as consumer demands for functionality and performance increase, the computing power and power consumption of these controllers are continuously rising, making heat dissipation an unavoidable issue. Currently, almost all autonomous driving controllers are installed inside the vehicle, such as under the seats, under the trunk, or on the side of the trunk. However, these are relatively sealed spaces with extremely poor heat dissipation conditions. Therefore, heat dissipation is necessary for the controllers to function properly.
[0003] Existing controller cooling solutions mostly use fans for heat dissipation, but this greatly increases the cost of the product, and fans also cause noise problems. Some controllers use automotive coolant for heat dissipation, but this requires the entire vehicle's water system to be used, increasing the overall vehicle cost. Utility Model Content
[0004] This utility model provides a heat dissipation structure and controller module to solve the problem of poor heat dissipation conditions for domain controllers in automobiles in the prior art.
[0005] According to a first aspect of the present invention, a heat dissipation structure is provided, including a component mounting part and a lower housing. The component mounting part is mounted on the upper surface of an automobile chassis for mounting a component module to be cooled. The lower housing is disposed on the upper surface of the automobile chassis at a position corresponding to the component mounting part, and at least a portion of the lower housing is exposed on the lower surface of the automobile chassis.
[0006] This utility model's heat dissipation structure places the component mounting part on the upper surface of the car chassis and utilizes the lower housing mounted at a corresponding position on the lower surface of the car chassis to dissipate heat to the outside of the car. This allows the heat from the component modules to be cooled to be transferred first to the lower housing, and then from the lower housing to the outside, thus achieving heat dissipation for these component modules. In this way, when the vehicle is stationary, the component modules, located at the bottom of the car chassis, are protected from direct sunlight, resulting in a lower temperature at the component module location compared to the surrounding environment and the interior temperature. When the vehicle is in motion, the high-speed airflow at the bottom of the car chassis rapidly cools the lower housing, thereby exchanging heat with the corresponding component modules and achieving heat dissipation for the component modules.
[0007] In some embodiments, the lower housing extends through the vehicle chassis, and the component mounting portion is connected to the lower housing.
[0008] Therefore, this configuration allows the component module to directly contact the lower housing for heat exchange, thereby improving heat dissipation efficiency.
[0009] In some embodiments, a sealing structure is provided between the lower housing and the vehicle chassis.
[0010] Therefore, by using this design, the installation gap between the lower housing and the car chassis can be sealed using a sealing structure, preventing water from seeping in through the installation gap when the car travels through areas with standing water.
[0011] In some embodiments, the sealing structure includes a sealing strip.
[0012] In some embodiments, a mounting structure is provided between the lower housing and the vehicle chassis, and the mounting structure is disposed on the upper surface of the vehicle chassis.
[0013] Therefore, this design allows the mounting structure to be housed inside the vehicle, preventing it from being exposed and thus improving the installation stability between the lower housing and the vehicle chassis.
[0014] In some embodiments, a heat exchange structure is provided on the lower housing.
[0015] Therefore, by using this configuration, the heat exchange structure can be used to accelerate the heat exchange between the lower shell and the outside.
[0016] In some embodiments, the heat exchange structure includes a heat dissipation fin structure.
[0017] Therefore, by using this configuration, the heat dissipation fin structure can be used to increase the contact area between the lower casing and the outside, thereby improving the heat exchange efficiency of the lower casing.
[0018] In some embodiments, the heat dissipation fin structure includes a heat dissipation channel structure formed by combining a plurality of fins, the heat dissipation channel structure having an airflow inlet configured such that its orientation is at an angle of less than 90 degrees to the direction of travel of the vehicle.
[0019] Therefore, this design allows airflow to pass through the overall heat dissipation fin structure from the airflow inlet while the car is moving, thereby accelerating the heat dissipation of the heat dissipation fins.
[0020] In some implementations, the airflow inlet is oriented in the same direction as the vehicle's forward movement.
[0021] Therefore, this design allows the airflow generated when the car is moving to enter the heat sink structure to the maximum extent, thereby further optimizing the overall heat dissipation efficiency.
[0022] According to a second aspect of the present invention, a controller module is provided, including a controller element module and the heat dissipation structure described in the first aspect, wherein the controller element module is disposed on the element mounting portion.
[0023] The controller module of this utility model has a significantly improved heat dissipation efficiency by setting the above-mentioned heat dissipation structure, and at the same time, it can eliminate the cost of adding fans or modifying water channels.
[0024] According to a third aspect of the present invention, an automobile is provided, comprising: an automobile chassis and the controller module described in the second aspect above; The controller module is installed on the vehicle chassis.
[0025] The automobile of this invention is equipped with the controller module described in the second aspect above. The controller module can utilize the high-speed airflow at the bottom of the automobile chassis for cooling when the automobile is moving, thereby achieving temperature control of the controller module and improving the working stability of the controller module.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0034] The present invention will now be described in further detail with reference to the accompanying drawings.
[0035] Figure 1 The overall structure of the heat dissipation structure according to one embodiment of this utility model is schematically shown. (Refer to...) Figure 1 As shown, the heat dissipation structure of this utility model includes the following parts: component mounting part 3 and lower housing 2.
[0036] The component mounting section 3 is a structure for mounting component modules that require heat dissipation. These component modules include, but are not limited to, heat-generating component modules such as controller modules and battery modules. For example, the component mounting section 3 can be configured as a flat plate structure mounted on the upper surface of the vehicle chassis 1, allowing the component modules to be mounted on it. The specific structure of the component mounting section 3 can also be designed according to the component modules to be mounted (e.g., configured as a housing to accommodate the component modules), and is not limited thereto.
[0037] The component mounting section 3 is mounted on the upper surface of the vehicle chassis 1, thereby preventing the component modules mounted on the component mounting section 3 from being exposed to the outside of the vehicle and providing better protection for the component modules. Furthermore, the heat from the component modules can also be conducted to the component mounting section 3, and then conducted to the vehicle chassis 1 for further dissipation, thereby improving heat dissipation efficiency and enhancing the heat dissipation effect.
[0038] The lower housing 2 is a structure used for heat exchange with the outside environment to dissipate heat from the component module to be cooled. The lower housing 2 is mounted on the vehicle chassis 1, and its mounting position corresponds to the mounting position of the component mounting portion 3 on the vehicle chassis 1. At least a portion of the lower housing 2 is exposed on the lower surface of the vehicle chassis 1, thereby effectively achieving heat exchange with the component module on the component mounting portion 3. Because the lower housing 2 is exposed on the lower surface of the vehicle chassis 1, it can be rapidly cooled by the high-speed airflow at the bottom of the vehicle chassis 1 when the vehicle is in motion, thus achieving heat dissipation for the component module. Specifically, the lower housing 2 can be mounted on the upper surface of the vehicle chassis 1, with an opening 11 in the vehicle chassis 1, allowing the lower housing 2 to penetrate the vehicle chassis 1 and partially expose itself on the lower surface of the vehicle chassis 1. Alternatively, the lower housing 2 can be directly mounted on the lower surface of the vehicle chassis 1, so that the lower housing 2 is completely exposed on the lower surface of the vehicle chassis 1, and heat exchange with the component mounting portion 3 is achieved through heat transfer from the vehicle chassis 1.
[0039] In some possible implementations, the lower housing 2 can be configured to penetrate the vehicle chassis 1 and be connected to the component mounting portion 3. Specifically, the vehicle chassis 1 can have an opening 11, allowing the lower housing 2 to penetrate the vehicle chassis 1. After penetrating the vehicle chassis 1, the lower housing 2 can be connected to the component mounting portion 3 via a connecting structure such as screws or clips, or the lower housing 2 can be mounted on the lower surface of the vehicle chassis 1, with the portion of the lower housing 2 penetrating the vehicle chassis 1 fitting snugly against the component mounting portion 3, thereby improving the heat exchange efficiency between the lower housing 2 and the component mounting portion 3. In this case, the size of the opening 11 can be set as large as possible, thereby maximizing the area of the integrated connection between the lower housing 2 and the component mounting portion 3, resulting in better heat transfer.
[0040] The lower housing 2 can also be configured to be integrated directly with the component mounting part 3. In this case, the size of the opening 11 is set to be equivalent to the size of the lower housing 2, so that when the component mounting part 3 is mounted on the upper surface of the vehicle chassis 1, the lower housing 2 can directly penetrate the vehicle chassis 1, and at least a portion of the lower housing 2 is exposed on the lower surface of the vehicle chassis 1.
[0041] In one embodiment, since the lower housing 2 penetrates through the vehicle chassis 1, it can be flush with the vehicle chassis 1 to avoid protruding and affecting the height of the vehicle chassis 1. In another embodiment, the lower housing 2 can also be designed to protrude from the vehicle chassis 1, which allows for better heat exchange between the lower housing 2 and the outside environment.
[0042] For example, refer to Figure 1 and Figure 3 As shown, in Figure 1 and Figure 3 In the illustrated embodiment, the opening 11 on the vehicle chassis 1 is square, corresponding to the shape of the lower housing 2, with rounded corners. The component mounting part 3 is integrally formed with the lower housing 2. The shape of the lower housing 2 corresponds to the opening 11 and is a square structure. Similarly, the structure of the component mounting part 3 is also set as a square structure corresponding to the opening 11. A raised edge 31 is provided around the periphery of the component mounting part 3, so that the component mounting part 3 can be disposed on the upper surface of the vehicle chassis 1, and the lower housing 2 can extend from the opening 11 to the lower surface of the vehicle chassis 1 and protrude, making the lower housing 2 exposed. A mounting groove 12 corresponding to the raised edge 31 on the component mounting part 3 can also be provided on the upper surface of the vehicle chassis 1, so that the component mounting part 3 can be better mounted on the vehicle chassis 1.
[0043] In some possible implementations, a sealing structure 4 can be provided between the lower housing 2 and the vehicle chassis 1, thereby sealing the installation gap between the lower housing 2 and the vehicle chassis 1 and preventing water or other impurities from seeping into the installation gap when the vehicle travels through areas with standing water. The sealing structure 4 can be a structure commonly used in the prior art, such as a sealing strip, sealing ring, or baffle, and is not limited thereto.
[0044] For example, refer to Figure 2 and Figure 3 As shown, in Figure 2 and Figure 3 In the illustrated embodiment, the sealing structure 4 is a sealing strip. Specifically, the sealing structure 4 is clamped between the protruding edge 31 and the mounting groove 12, thereby enabling the sealing structure 4 to completely seal the gap between the lower housing 2 and the vehicle chassis 1, achieving a sealing effect.
[0045] In some possible implementations, a mounting structure can be provided between the lower housing 2 and the vehicle chassis 1 to allow the lower housing 2 to be mounted and fixed to the vehicle chassis 1. The mounting structure can be located on the upper surface of the vehicle chassis 1, thereby avoiding exposure of the mounting structure and improving the installation stability between the lower housing 2 and the vehicle chassis 1. Specific mounting structures can be commonly used in the prior art, such as snap-fit, spring-loaded clips, screw and threaded hole structures, and are not limited thereto.
[0046] For example, refer to Figures 1 to 3 As shown, in Figures 1 to 3In the illustrated embodiment, the mounting structure is a screw and screw hole structure. Specifically, a mounting plate 32 extends outward from the upper surface of the lower housing 2, while a mounting step 13 is provided at a corresponding position on the upper surface of the vehicle chassis 1. In this embodiment, the lower housing 2 and the component mounting part 3 are integrally formed, and the mounting plate 32 can also be provided at the edge of the component mounting part 3. Exemplarily, four mounting plates 32 are provided on the lower housing 2, and two are symmetrically provided on each side of the lower housing 2. Mounting holes 33 are provided on the mounting plates 32, and mounting screw holes 14 corresponding to the positions of the mounting holes 33 are provided on the mounting steps 13. Since mounting steps 13 are provided on the upper surface of the vehicle chassis 1, screws can be prevented from penetrating the vehicle chassis 1 during installation, thus avoiding affecting the sealing performance. During installation, the mounting holes 33 on the four mounting plates 32 of the lower housing 2 are aligned with the mounting screw holes 14 on the mounting steps 13 on the upper surface of the vehicle chassis 1, and then the mounting screws 34 are screwed in and tightened.
[0047] In some possible embodiments, a heat exchange structure may also be provided on the lower housing 2. Specifically, the heat exchange structure may be located on the side of the lower housing 2 away from the vehicle chassis 1. In some embodiments where the lower housing 2 protrudes from the vehicle chassis 1, the heat exchange structure may also be located on the side of the lower housing 2.
[0048] The heat exchange structure can be specifically configured as a common cooling fan, a heat dissipation fin structure 21, etc. When the heat exchange structure is configured as a cooling fan, in some possible embodiments, the air outlet of the cooling fan can be set at an angle such as 45° to face the surface of the lower housing 2. This allows the airflow to blow on the cooling fan when the car is in motion, thereby changing the airflow direction behind the cooling fan and directing it to the surface of the lower housing 2, thus accelerating the heat exchange and cooling of the lower housing 2.
[0049] When the heat exchange structure is configured as a heat dissipation fin structure 21, in some possible embodiments, the heat dissipation fin structure 21 may include a plurality of fins protruding from the surface of the lower housing 2. The arrangement of the fins can effectively increase the contact area between the lower housing 2 and the outside, thereby effectively improving the heat exchange efficiency between the lower housing 2 and the outside. The fins can be arranged in parallel or side by side, thereby forming a plurality of heat dissipation flow channel structures 22 from a plurality of adjacent fins.
[0050] The heat dissipation channel structure 22 can be configured as a straight line, an arc shape, or an irregular shape. The heat dissipation channel structure 22 has an airflow inlet and an airflow outlet. When air enters through the airflow inlet of the heat dissipation channel structure 22 and exits through the airflow outlet, it quickly carries away the heat from the fins on both sides of the heat dissipation channel structure 22, thereby achieving rapid cooling of the lower casing 2.
[0051] In this design, the airflow inlet of the heat dissipation channel structure 22 can be configured such that the angle between its orientation and the vehicle's forward direction is less than 90°. This allows at least a portion of the high-speed airflow from the vehicle's chassis to flow into the heat dissipation channel structure 22 through its airflow inlet during normal driving. As a preferred embodiment, the airflow inlet of the heat dissipation channel structure 22 can be oriented in the same direction as the vehicle's forward direction, thereby maximizing the amount of high-speed airflow entering the heat dissipation channel structure 22 during driving and effectively removing heat from the lower housing 2.
[0052] For example, refer to Figure 1 and Figure 3 As shown, in Figure 1 and Figure 3 In the illustrated embodiment, a heat dissipation fin structure 21 is provided on the surface of the lower housing 2. The fins on the heat dissipation fin structure 21 are all straight and are arranged along the direction of travel of the vehicle. This ensures that the airflow inlet of the heat dissipation channel structure 22 formed by adjacent fins faces the same direction as the vehicle's travel. This arrangement maximizes the airflow generated when the vehicle is moving into the heat dissipation fin structure 21, thereby optimizing the overall heat dissipation efficiency of the lower housing 2.
[0053] The heat dissipation structure of this utility model involves placing the component mounting part 3 on the upper surface of the car chassis 1 and utilizing the lower housing 2, which is mounted at a corresponding position on the lower surface of the car chassis 1, to dissipate heat to the outside of the car. This allows the heat from the heat-dissipating component modules to be transferred first to the lower housing 2, and then from the lower housing 2 to the outside, thus achieving heat dissipation for these component modules. In this way, when the vehicle is stationary, the component modules, located at the bottom of the car chassis 1, are protected from direct sunlight, resulting in a lower temperature at the location of the component modules compared to the surrounding environment and the interior temperature. When the vehicle is in motion, the high-speed airflow at the bottom of the car chassis 1 rapidly cools the lower housing 2, thereby exchanging heat with the corresponding component modules and achieving heat dissipation for the component modules.
[0054] Figure 1 The schematic diagram illustrates the structural composition of a controller module according to one embodiment of the present invention, with reference to... Figure 1 As shown, the controller module of this utility model includes a controller element module 5 and a heat dissipation structure as described in any of the above embodiments.
[0055] In one embodiment, the controller component module 5 may include an upper housing and a circuit board structure disposed inside the housing. The circuit board structure has a controller connector 51, and the upper housing has an opening for exposing the controller connector 51. The controller connector 51 is used to achieve electrical connection between the module and an external device. The controller component module 5 can be bolted to the component mounting portion 3, thereby ensuring the installation stability of the controller component module 5. Exemplarily, when the component mounting portion 3 and the lower housing 2 are integrated, the circuit board structure can be accommodated within the cavity formed by the upper housing and the lower housing 2, and the upper housing and the lower housing can be fixedly mounted with bolts.
[0056] At the same time, this arrangement allows the controller component module 5 to be installed on the upper surface of the vehicle chassis 1, so as to avoid the controller component module 5 being exposed to the outside of the vehicle, and facilitates the connection of the controller component module 5 with other components inside the vehicle, and also helps to protect the controller component module 5.
[0057] The controller module of this utility model has a significantly improved heat dissipation efficiency by setting the above-mentioned heat dissipation structure, and at the same time, it can eliminate the cost of adding fans or modifying water channels.
[0058] This utility model also provides an automobile, which includes an automobile chassis 1 and a controller module according to any of the above embodiments. The automobile can be various types of vehicles, such as gasoline vehicles, electric vehicles, hybrid vehicles, and driverless cars. An opening 11 can be provided on the automobile chassis 1 for mounting the controller module. When the controller module is mounted on the automobile chassis 1, at least a portion of the lower housing 2 is exposed at the bottom of the automobile chassis 1, allowing for cooling by utilizing the high-speed airflow at the bottom of the automobile chassis 1 during vehicle movement, thereby achieving temperature control of the controller module and improving its operational stability.
[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
