Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, specifically to a flip-up heat dissipation duct. Background Technology

[0002] In the design of the cooling system of electric loaders, the sustained and efficient operation of the radiator is crucial. Currently, electric loader radiators typically use four sets of electric fans to enhance the cooling effect. These fans are mounted on the air guide shroud. However, most existing air guide shrouds are directly fixed to the radiator frame with bolts. Although this rigid connection method is simple in structure, it brings great inconvenience to maintenance and dust removal.

[0003] Traditionally, radiators and air guide covers are directly fixed by welding or bolts. When the radiator core needs cleaning due to blockage by dust, lint, or other debris, maintenance personnel lack effective operating space. They can usually only try to rinse the radiator core from the side with an air gun. This method is not only difficult to exert force due to the narrow space, but more importantly, the dust blown out often enters and accumulates inside the immovable air guide cover, causing secondary pollution. When the dust accumulates to a certain extent, it can even affect the normal operation of the fan, ultimately forcing maintenance personnel to perform the most undesirable operation—disassembling the entire air guide cover for thorough cleaning. This process is time-consuming and laborious, seriously affecting the equipment's uptime. Utility Model Content

[0004] The purpose of this invention is to provide a flip-up heat dissipation duct that can solve the technical problem of time-consuming and labor-intensive cleaning of existing ducts.

[0005] To achieve the above objectives, this utility model proposes a flip-up heat dissipation shroud, including a shroud with a first window, a heat sink core disposed within the first window, a hinged flap connected to the shroud, a second window corresponding to the first window on the flap, an electronic fan fixedly mounted on the side of the second window, and the flap being fixed to the shroud by several handle bolts.

[0006] Further configured, the flap includes a first flap and a second flap, which are respectively mounted on the upper side of the air guide cover via hinges. The use of a split first flap and a second flap brings significant advantages in modularity and lightweight design.

[0007] Further configured, the hinge includes a first leaf fixedly installed on the upper side wall of the air guide cover, the first leaf being rotatably connected to a second leaf via a pin, and the second leaf being fixedly installed on the upper side wall of the flap. This hinge structure specifies the rotation mechanism of the flap, ensuring that the flap is stable and reliable during opening and closing, and avoiding offset or jamming.

[0008] Further configured, the flap has several round holes on its edge, and the air guide has several screw holes corresponding to the round holes. After the handle bolt passes through the round holes and screw holes, the flap is fixed to the air guide. Through the cooperation of the round holes and screw holes, as well as the use of the handle bolt, the flap can be quickly fixed and released. Maintenance personnel can operate it by hand without tools, which greatly shortens the opening and closing time.

[0009] A further feature is that the flap is fixedly equipped with a door handle. The addition of the door handle provides a user-friendly operating point, allowing maintenance personnel to easily and safely grasp and operate the flap, especially when the flap is loaded with an electronic fan, thus avoiding damage caused by slippage or improper force.

[0010] A further configuration includes a fan plug on the flap, which is connected to an electronic fan. The fan plug is connected to an external power supply via a wiring harness. The design of the fan plug and wiring harness enables quick electrical connection and disconnection of the electronic fan. When the flap is opened, the wiring harness is allowed to move to a certain extent without hindering maintenance operations, while ensuring the reliability of the power connection.

[0011] Further configured, the first window is a square hole with rounded corners at the four corners. The first window adopts a square hole with rounded corners design, which maximizes the exposed area of ​​the radiator core and facilitates comprehensive cleaning by maintenance personnel.

[0012] Further configuration involves the second window being a circular hole. This design optimizes the installation of the electric fan and the airflow channel, reduces wind resistance and turbulence, and improves cooling efficiency.

[0013] Further, the diameter of the second window is smaller than the width of the first window. By making the diameter of the second window smaller than the width of the first window, it is ensured that when the flap is closed, the electronic fan is completely aligned with the heat sink core, avoiding airflow leakage or deviation, thereby optimizing the cooling effect.

[0014] A further configuration is that the line connecting the geometric center of the second window and the geometric center of the second window is perpendicular to the surface of the air guide shroud. This feature ensures that the center of the electric fan is precisely aligned with the center of the heat sink core, so that the airflow evenly covers the entire core surface.

[0015] The beneficial effects of one or more of the above technical solutions: Creating an unobstructed working space to ensure thorough cleaning: Traditional methods attempt to clean dust with an air gun on narrow sides, which is awkward to operate and easily blows dust into the air guide shroud, causing secondary pollution. This utility model provides operators with an open, frontal, and unobstructed operating window by flipping a flap. Maintenance personnel can directly rinse or clean the entire radiator core with an air gun from the front, ensuring that every heat dissipation fin is thoroughly cleaned without any dead corners, fundamentally solving the problems of incomplete cleaning and dust accumulation inside the air guide shroud.

[0016] Simplified operation process, significantly reducing labor intensity and time cost: This utility model separates the fan from the fixed air guide cover and installs it on a flip-up plate fixed by hinges and handle bolts. Traditional fixed designs require the removal of multiple bolts to remove the air guide cover, which is time-consuming and laborious, often taking tens of minutes or even longer. However, this utility model only requires loosening a few handle bolts by hand (without any tools) to flip the plate and the fan together by 90 degrees, completely exposing the radiator core within tens of seconds, thus improving equipment uptime and work efficiency.

[0022] The specific implementation of this embodiment will now be described with reference to the accompanying drawings.

[0023] A flip-up heat dissipation shroud, as shown in the reference. Figure 1 , Figure 2 and Figure 3 It includes an air guide cover 2, which has a first window 21. A heat sink core is installed inside the first window 21. The air guide cover 2 is connected to a flap 3 via a hinge 5. A second window 34 is opened on the flap 3 corresponding to the first window 21. An electronic fan 1 is fixedly installed on the side of the second window 34. The flap 3 is fixed to the air guide cover 2 by several handle bolts 4.

[0024] The flap 3 includes a first flap 31 and a second flap 32, which are respectively mounted on the upper side of the air guide shroud 2 via hinges 5. By dividing the flap 3 into a first flap 31 and a second flap 32, and independently hinged to the upper side of the air guide shroud 2, a modular design is achieved. This allows maintenance personnel to open one flap individually for local cleaning or maintenance as needed, thus providing more flexible operating space. This further simplifies the maintenance process, especially in large radiator systems, reducing unnecessary operating steps and improving maintenance efficiency and focus.

[0025] The hinge 5 includes a first leaf 51 fixedly mounted on the upper side wall of the air guide shroud 2. The first leaf 51 is rotatably connected to a second leaf 52 via a pin 53. The second leaf 52 is fixedly mounted on the upper side wall of the flap 3. This hinge 5 structure specifies the rotation mechanism of the flap 3, ensuring that the flap 3 is stable and reliable during opening and closing, and avoiding offset or jamming. This simple and durable design improves the overall mechanical strength, extends the service life, and facilitates manufacturing and installation, ensuring smooth and repeatable maintenance operations and reducing the risk of failure.

[0026] Several round holes 33 are formed along the edge of the flap 3, and several screw holes 22 are formed in the air guide cover 2 corresponding to the round holes 33. The handle bolt 4 passes through the round holes 33 and screw holes 22 to fix the flap 3 to the air guide cover 2. Through the cooperation of the round holes 33 and screw holes 22, and the use of the handle bolt 4, the flap 3 can be quickly fixed and released. Maintenance personnel can operate it by hand without tools, which greatly shortens the opening and closing time (from tens of minutes in the traditional way to tens of seconds). This design significantly reduces labor intensity, improves maintenance efficiency, and ensures that the flap 3 is tightly fixed when closed, preventing vibration or noise during operation.

[0027] A door handle 7 is fixedly installed on the flap 3. The addition of the door handle 7 provides a user-friendly operating point, allowing maintenance personnel to easily and safely grip and operate the flap 3, especially when the flap 3 is loaded with the electric fan 1, preventing damage caused by slippage or improper force. This further improves operational convenience and safety, conforms to ergonomic principles, and reduces the risk of accidents during maintenance.

[0028] The flip panel 3 is equipped with a fan connector 6, which is an existing wiring harness connector. The fan connector 6 model number is Yazaki 7283-8497-90 (Japan). After connecting to the electronic fan 1, the fan connector 6 connects to an external power supply via wiring harness 8. The design of the fan connector 6 and wiring harness 8 allows for quick electrical connection and disconnection of the electronic fan 1. When the flip panel 3 is opened, the wiring harness 8 is allowed to move to a certain extent without hindering maintenance operations, while ensuring the reliability of the power connection. This avoids wear or short circuit problems that may occur in traditional wiring, improves system safety and maintainability, and makes fan removal and installation more convenient.

[0029] The first window 21 is a square hole with rounded corners at all four corners. This square hole design maximizes the exposed area of ​​the radiator core, facilitating thorough cleaning by maintenance personnel. Simultaneously, the rounded corners reduce stress concentration, improving the structural strength and durability of the air guide shroud 2. Furthermore, the rounded corners avoid the risk of scratches from sharp corners, enhancing operational safety and ensuring thorough cleaning without any blind spots.

[0030] The second window 34 is a circular hole. This circular hole optimizes the installation and airflow path of the electric fan 1, reduces wind resistance and turbulence, and improves cooling efficiency. The circular design facilitates compatibility with standard fans, simplifies manufacturing and assembly, and ensures uniform airflow distribution, contributing to efficient heat exchange within the radiator core and enhancing overall heat dissipation performance.

[0031] The diameter of the second window 34 is smaller than the width of the first window 21. By making the diameter of the second window 34 smaller than the width of the first window 21, it is ensured that when the flap 3 is closed, the electric fan 1 is completely aligned with the heat sink core, avoiding airflow leakage or misalignment, thereby optimizing the cooling effect. At the same time, this design prevents dust from entering the interior of the air guide shroud 2 from the edges, reducing the risk of secondary pollution and maintaining the cleanliness and stable operation of the system.

[0032] The line connecting the geometric center of the second window 34 and the geometric center of the first window 21 is perpendicular to the surface of the air guide shroud 2. This feature ensures that the center of the electric fan 1 is precisely aligned with the center of the heat sink core, allowing airflow to evenly cover the entire core surface and avoiding localized overheating or insufficient cooling. This centering design improves heat dissipation efficiency, extends the lifespan of the heat sink, reduces energy consumption, and ensures reliable system operation under various conditions.

[0033] The specific steps for cleaning are as follows: Four sets of electronic fans 1 are bolted to flaps 3 (i.e., the door panels mentioned in the text, specifically the first flap 31 and the second flap 32). One end of flap 3 is connected to the air guide shroud 2 via three sets of hinges 5. The first leaf 51 of the hinge 5 is welded to the air guide shroud 2, and the second leaf 52 is welded to flap 3, with a pin 53 connecting them in the middle. The remaining ends of flap 3 are fixed to the air guide shroud 2 by handle bolts 4, which can be tightened or loosened by hand without the aid of wrenches or other tools. A door handle 7 is welded to flap 3. Fan inserts 6 are fixed to flap 3, and wiring harnesses 8 are routed and fixed to the air guide shroud 2 to ensure that they do not affect the opening of flap 3. When it is necessary to manually clean the radiator core, the handle bolts 4 on flap 3 can be removed by hand, allowing flap 3 to be flipped 90 degrees to expose the radiator core for cleaning.

[0034] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
