Description

Technical Field

[0001] This utility model relates to the field of electronic device chassis technology, and specifically to a heat dissipation chassis. Background Technology

[0002] Most common electronic device chassis are enclosed structures, which provide protection against salt spray, mold, sand, dust, rain, damp heat, impact, vibration, and electromagnetic shielding. Inside the chassis, the chips on the printed circuit board generate a significant amount of heat during operation. This heat is conducted to the module's heat-conducting plate, and then through the heat dissipation fins on both sides of the plate. Outside cool air exchanges heat through these fins via convection, carrying the heat away. However, some of the heat-carrying air remains inside the chassis, affecting heat dissipation. Furthermore, the heat dissipation fins only contact the mounting surfaces at both ends of the module, resulting in a small contact area where most heat cannot be expelled, especially with chips that have high thermal power. Even with increased fan airflow, it is difficult to remove the heat effectively.

[0003] In addition, the chassis of common electronic devices are arranged vertically with small gaps between modules. The heat generated by the modules will accumulate and rise in temperature. The heat cannot be dissipated in the sealed space, which may lead to equipment failure or reduced reliability. Utility Model Content

[0004] To solve at least one of the above technical problems, this utility model provides a heat dissipation chassis.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: This utility model provides a heat dissipation chassis, including a shell, an air duct assembly inside the shell, and a mounting position for installing functional modules on at least one side of the air duct assembly; the air duct assembly has a ventilation cavity that extends through both ends, a fan is provided at one end of the ventilation cavity, an air inlet plate is provided at one end of the air duct assembly, and an air outlet plate is provided at the other end of the air duct assembly; the fan is used to drive airflow from the air inlet plate into the ventilation cavity and out of the air outlet plate; windows are opened at both ends of the shell corresponding to the air inlet plate and the air outlet plate, respectively.

[0006] The beneficial effects of this utility model are: This invention utilizes mounting positions on the air duct assembly to install functional modules, allowing the modules to have a large contact area with the air duct assembly for heat conduction. Simultaneously, a fan drives airflow from the inlet plate into the ventilation cavity, and the heat-carrying airflow flows directly out of the housing from the outlet plate, preventing hot air from remaining inside the chassis and achieving high-efficiency heat dissipation. Furthermore, the functional modules are enclosed within the space between the outside of the air duct assembly and the inside of the housing, providing ideal protection against salt spray and dust, as well as good electromagnetic shielding. Moreover, when multiple functional modules are present, they can be arranged along the outside of the air duct assembly, preventing overlapping and heat generation. When multiple chassis are arranged, the fixed airflow directions prevent mutual interference and ensure effective heat dissipation.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the air duct assembly includes a rectangular cylinder, with multiple heat-conducting strips on the upper and / or lower sides of the rectangular cylinder. The multiple heat-conducting strips are arranged along the length of the rectangular cylinder, and a mounting position for installing the functional module is formed between every two heat-conducting strips.

[0009] The bottom mounting surface of the functional module contacts the upper side of the rectangular cylinder for heat conduction. At the same time, the side of the functional module contacts the heat conduction strip for heat conduction. The heat conduction strip can conduct heat to the rectangular cylinder for heat dissipation, which increases the heat conduction area of ​​the functional module and improves the heat dissipation efficiency.

[0010] Furthermore, nano-carbon copper foil is sandwiched between the heat-conducting strip and the rectangular cylinder.

[0011] The thermal conductivity of nano-carbon copper foil is greater than 2000 W / m·K, which is much greater than that of aluminum alloy itself, making it easier for the heat-conducting strip to efficiently transfer heat to the rectangular cylinder.

[0012] Furthermore, both the surface of the heat-conducting strip and the surface of the rectangular cylinder are coated with nano-carbon copper foil.

[0013] This facilitates improving the heat transfer efficiency of the heat-conducting strip and the rectangular cylinder.

[0014] Furthermore, both the rectangular cylinder and the heat-conducting strip are made of aluminum alloy.

[0015] It is easy to manufacture and has high thermal conductivity.

[0016] Furthermore, at least one end of the rectangular cylinder is fixed with a flared air guide shroud, and the ventilator is located inside the air guide shroud.

[0017] This facilitates increasing the air intake and exhaust volume, thereby improving heat dissipation efficiency.

[0018] Furthermore, both ends of the rectangular cylinder are fixed with air guide hoods, and the air inlet plate and air outlet plate are respectively fixedly connected to the ends of the corresponding air guide hoods.

[0019] This helps prevent foreign objects from entering the air duct assembly.

[0020] Furthermore, the end edge of the air guide shroud corresponds to and fits the window edge of the housing, and the air inlet plate and air outlet plate are located on the outside of the housing; multiple first screws are distributed on the edge of the air inlet plate, the first screws penetrate the air inlet plate and one end side wall of the housing and are fixedly connected to the air guide shroud corresponding to the air inlet plate; multiple second screws are distributed on the edge of the air outlet plate, the second screws penetrate the air outlet plate and the other end side wall of the housing and are fixedly connected to the air guide shroud corresponding to the air outlet plate.

[0021] This design facilitates the integration of the air inlet plate, air outlet plate, housing, and duct assembly into a single unit, improving the stability of the duct assembly. At the same time, the end edge of the air guide cover corresponds to and fits snugly with the window edge of the housing, ensuring the functional module's ability to resist salt spray and sand dust, as well as its good electromagnetic shielding effect.

[0022] Furthermore, the bottom of the housing is provided with a removable base plate, which forms the lower sidewall of the housing.

[0023] It facilitates the assembly of air duct components and functional modules on the base plate, and then installs them into the housing along with the base plate, making installation convenient.

[0024] Furthermore, the shell is provided with cover plates on opposite sides, and the cover plates are provided with multiple strip-shaped ventilation holes. The cover plates are connected to the shell by screws.

[0025] When increased heat dissipation is required, the opposite side walls of the housing are replaced with cover plates with strip-shaped ventilation holes to facilitate increased heat dissipation; when the sealing of functional modules is required, the opposite side walls of the housing are replaced with closed cover plates to facilitate the internal electromagnetic shielding effect.

Detailed Implementation

[0031] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0032] This utility model refers to Figure 1-4 .

[0033] This utility model provides a heat dissipation chassis, including a shell 1, an air duct assembly 2 inside the shell 1, and an installation position for installing a functional module 6 on at least one side of the air duct assembly 2; the air duct assembly 2 has a ventilation cavity that runs through both ends, a fan 5 at one end of the ventilation cavity, an air inlet plate 3 at one end of the air duct assembly 2, and an air outlet plate 4 at the other end of the air duct assembly 2; the fan 5 is used to drive airflow from the air inlet plate 3 into the ventilation cavity and out through the air outlet plate 4; windows are opened at both ends of the shell 1 corresponding to the air inlet plate 3 and the air outlet plate 4, respectively.

[0034] Working principle: Functional module 6 is an integrated circuit component within the chassis, belonging to existing technology. Functional module 6 generates heat during operation. Its bottom mounting surface and sides can contact the air duct assembly 2 via mounting points, providing a large contact area for efficient heat conduction. The heat from functional module 6 is transferred to the air duct assembly 2, where the fan 5 drives a cool airflow from one end of the housing 1 through the air inlet plate 3 into the ventilation cavity, carrying away the heat. The heat-laden airflow then flows directly out of the housing 1 through the air outlet plate 4, achieving highly efficient heat dissipation. This ensures continuous operation at high temperatures, extends module lifespan, and improves equipment stability.

[0035] Note: The air duct assembly 2 can be fixedly connected to the inside of the housing 1, or it can be left unfixed. The air inlet plate 3 and the air outlet plate 4 are mesh plates.

[0036] This invention utilizes a mounting position on the air duct assembly 2 for installing the functional module 6, allowing the functional module 6 to have a large contact area with the air duct assembly 2 for heat conduction. Simultaneously, the fan 5 drives airflow from the inlet plate 3 into the ventilation cavity, and the heat-carrying airflow flows directly out of the housing 1 from the outlet plate 4, preventing hot air from remaining inside the chassis and achieving high-efficiency heat dissipation. Furthermore, the functional module 6 is enclosed within the space between the outside of the air duct assembly 2 and the inside of the housing 1, providing ideal protection against salt spray and dust, as well as good electromagnetic shielding. Moreover, when there are multiple functional modules 6, they can be arranged along the outside of the air duct assembly 2, preventing overlapping and overheating. When multiple chassis are arranged, the fixed air inlet and outlet directions prevent mutual interference between chassis, thus avoiding affecting heat dissipation.

[0037] Furthermore, the air duct assembly 2 includes a rectangular cylinder 21, with multiple heat-conducting strips 22 on the upper and / or lower sides of the rectangular cylinder 21. The multiple heat-conducting strips 22 are arranged along the length of the rectangular cylinder 21, and a mounting position for installing the functional module 6 is formed between every two heat-conducting strips 22.

[0038] In this embodiment, three scenarios are included: multiple heat-conducting strips 22 are provided only on the upper side of the rectangular cylinder 21; multiple heat-conducting strips 22 are provided only on the lower side of the rectangular cylinder 21; and multiple heat-conducting strips 22 are provided on both the upper and lower sides of the rectangular cylinder 21. This saves space. A ventilation cavity with both ends extending through is formed inside the rectangular cylinder 21.

[0039] The bottom mounting surface of the functional module 6 contacts the upper side of the rectangular cylinder 21 for heat conduction. At the same time, the side of the functional module 6 contacts the heat conduction strip 22 for heat conduction. The heat conduction strip 22 can conduct heat to the rectangular cylinder 21 for heat dissipation, which increases the heat conduction area of ​​the functional module 6 and improves the heat dissipation efficiency.

[0040] Furthermore, a nano-carbon copper foil is sandwiched between the heat-conducting strip 22 and the rectangular cylinder 21.

[0041] The thermal conductivity of the nano-carbon copper foil is greater than 2000 W / m·K, which is much greater than that of the aluminum alloy itself, making it easier for the heat-conducting strip 22 to efficiently conduct heat to the rectangular cylinder 21.

[0042] Furthermore, both the surface of the heat-conducting strip 22 and the surface of the rectangular cylinder 21 are coated with nano-carbon copper foil.

[0043] In this embodiment, the nano-carbon copper foil can be fixed to the surface of the heat-conducting strip 22 and the surface of the rectangular cylinder 21 by pasting.

[0044] This facilitates improving the heat transfer efficiency of the heat-conducting strip 22 and the rectangular cylinder 21.

[0045] Furthermore, both the rectangular cylinder 21 and the heat-conducting strip 22 are made of aluminum alloy.

[0046] It is easy to manufacture and has high thermal conductivity.

[0047] Furthermore, at least one end of the rectangular cylinder 21 is fixed with a flared air guide hood 23, and the ventilator 5 is located inside the air guide hood 23.

[0048] Note: The ventilator 5 may or may not be fixed inside the air guide shroud 23. The flared air guide shroud 23 has its small end matched and fixedly connected to the end of the rectangular cylinder 21, and its cross-sectional area gradually increases from the small end to the large end.

[0049] This facilitates increasing the air intake and exhaust volume, thereby improving heat dissipation efficiency.

[0050] Furthermore, both ends of the rectangular cylinder 21 are fixed with air guide hoods 23, and the air inlet plate 3 and the air outlet plate 4 are respectively fixedly connected to the ends of the corresponding air guide hoods 23.

[0051] This facilitates the prevention of foreign objects from entering the air duct assembly 2.

[0052] Furthermore, the end edge of the air guide shroud 23 corresponds to and fits the window edge of the housing 1, and the air inlet plate 3 and the air outlet plate 4 are located on the outside of the housing 1; multiple first screws are distributed on the edge of the air inlet plate 3, the first screws penetrate the air inlet plate 3 and one end side wall of the housing 1 and are fixedly connected to the air guide shroud 23 corresponding to the air inlet plate 3; multiple second screws are distributed on the edge of the air outlet plate 4, the second screws penetrate the air outlet plate 4 and the other end side wall of the housing 1 and are fixedly connected to the air guide shroud 23 corresponding to the air outlet plate 4.

[0053] This facilitates the integration of the air inlet plate 3, air outlet plate 4, housing 1, and air duct assembly 2 into a single unit, improving the stability of the air duct assembly 2. At the same time, the end edge of the air guide shroud 23 corresponds to and fits into the window edge of the housing 1, ensuring the anti-salt spray and dust resistance and good electromagnetic shielding effect of the functional module 6.

[0054] Furthermore, the bottom of the housing 1 is provided with a detachable bottom plate 7, which forms the lower side wall of the housing 1.

[0055] Preferably, the base plate 7 is connected to the housing 1 by screws.

[0056] It is convenient to assemble the air duct assembly 2 and the functional module 6 on the base plate 7, and then install them into the housing 1 along with the base plate 7, making installation easy.

[0057] Furthermore, cover plates 8 are provided on opposite sides of the housing 1, and multiple strip-shaped ventilation holes 9 are provided on the cover plates 8. The cover plates 8 are connected to the housing 1 by screws.

[0058] When increased heat dissipation is required, the opposite side walls of housing 1 are replaced with cover plates 8 having strip-shaped ventilation holes 9 to facilitate increased heat dissipation; when the sealing of functional module 6 is required, the opposite side walls of housing 1 are replaced with closed cover plates 8 to facilitate the internal electromagnetic shielding effect.
