Description

Technical Field

[0001] This utility model relates to the field of heat dissipation equipment technology, and in particular to a heat dissipation component and an articulated dump truck. Background Technology

[0002] Currently, articulated dump trucks have an engine hood with vents for expelling hot air. The truck also has a cooling system including a radiator, cooling fan, and a fairing. The fairing's guide end faces the vent. When the truck is operating, the engine's operation raises the coolant temperature, causing the radiator and cooling fan to draw in a large amount of hot air, creating a hot airflow that flows through the fairing, across the vent, and ultimately out of the truck's engine compartment. However, in existing technology, a large gap exists between the fairing's guide end and the vent. This causes some hot air to escape through this gap, failing to reach the vent. This unexited hot air is then bounced off the fairing and flows back to the radiator's intake, causing hot air recirculation and increasing the radiator's intake temperature, thus affecting cooling efficiency. To continue meeting the heat dissipation requirements, the cooling fan speed needs to be increased, which in turn leads to an increase in engine speed and fuel consumption. Utility Model Content

[0003] The purpose of this invention is to provide a heat dissipation component and an articulated dump truck, which effectively improves the effectiveness of airflow guidance and avoids the problem of excessive hot air backflow.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0008] A cooling fan is rotatably mounted inside the air guide shroud;

[0009] An air guard ring is disposed within the airflow guide gap. The first end of the air guard ring is sleeved on the second end of the airflow guide shroud, and the second end of the air guard ring is connected to the machine cover. The air guard ring is connected to the air outlet.

[0010] Preferably, the windshield is made of a flexible and deformable material.

[0011] Preferably, the second end of the wind shield is provided with an annular support base, the air outlet is located inside the support base, and the side face of the shroud facing the air guide is provided with a connecting part, and the support base is fixedly connected to the connecting part.

[0012] Preferably, the support base is provided with multiple brackets spaced circumferentially, and the brackets are fixedly connected to the connecting part.

[0013] Preferably, the bracket includes a first fixing part and a second fixing part that are bent in an L-shape, the first fixing part being fixed to the annular support base and the second fixing part being fixed to the connecting part.

[0014] Preferably, the first fixing part is provided with a first connecting hole, the second end of the wind shield is provided with a through hole, and the support base is provided with a first mounting hole.

[0037] This embodiment provides an articulated dump truck, see reference. Figures 1 to 4 As shown, the articulated dump truck includes a body (not shown), on which a shroud 6 is mounted. The shroud 6 has an air outlet 61 communicating with the external environment. The articulated dump truck also includes a heat dissipation assembly. The heat dissipation assembly includes a radiator 1, a deflector 2, a cooling fan 3, and a wind guard 4. The radiator 1 is mounted on the body. The first end of the deflector 2 is connected to the radiator 1, and the second end of the deflector 2 extends toward the side where the shroud 6 is located. A flow guiding gap is formed between the side of the shroud 6 facing the deflector 2 and the deflector 2. The cooling fan 3 is rotatably mounted inside the deflector 2. The wind guard 4 is located within the flow guiding gap. The first end of the wind guard 4 is fitted onto the second end of the deflector 2, and the second end of the wind guard 4 is connected to the shroud 6. The wind guard 4 communicates with the air outlet 61.

[0038] In this embodiment, a protective ring 4 is provided in the airflow gap between the air deflector 2 and the engine shroud 6. The first end of the protective ring 4 is fitted onto the second end of the air deflector 2, and the second end is connected to the engine shroud 6 and communicates with the air outlet 61 opened on the engine shroud 6. The protective ring 4 can effectively guide the hot air located in the airflow gap. After the hot airflow flows from the first end to the second end of the air deflector 2, it effectively flows through the air outlet 61 through the protective ring 4 and is finally effectively discharged to the external environment. This effectively improves the discharge rate of the hot airflow, reduces the possibility of the hot airflow flowing out from the airflow gap, effectively reduces the degree of hot air backflow, reduces the mixing of the rebound hot airflow at the air inlet of the radiator 1, reduces the air inlet temperature of the radiator 1, and reduces the possibility of increased fuel consumption due to increased engine speed.

[0039] In this embodiment, the air outlet 61 is configured with a honeycomb mesh structure.

[0040] In this embodiment, the air shield 4 is made of a flexible and deformable material. With this configuration, when the housing 6 changes position, the second end of the air shield 4 moves with the housing 6, maintaining the connection between both ends of the air shield 4 and the air guide 2 and the housing 6, and maintaining the airflow relationship between the air guide 2 and the air outlet 61.

[0041] Optionally, the windshield ring 4 is made of rubber. Rubber is elastic at room temperature, capable of undergoing large deformation under small external forces, and quickly returning to its original shape after the external force is removed. In addition, rubber also possesses properties such as high elasticity, viscoelasticity, electrical insulation, corrosion resistance, and aging resistance.

[0042] In this embodiment, a support base 5 is provided at the second end of the air shield 4, and a connecting part is provided on the side of the cover 6 facing the air guide shroud 2. The support base 5 is fixedly connected to the connecting part. Specifically, the support base 5 is located outside the air outlet 61, and the support base 5 is in close contact with the connecting part. This allows the hot airflow passing through the air shield 4 to pass through the air outlet 61 as much as possible, further improving the hot airflow throughput and reducing the degree of hot air recirculation.

[0043] Optionally, the support base 5 can be C-shaped or annular, providing a skeletal-like support for the flexible air shield 4. The connecting part is a convex ring structure coaxial with the air outlet 61, which allows for better fit and contact with the C-shaped or annular support base 5.

[0044] In this embodiment, the support base 5 is provided with multiple brackets 51 at circumferential intervals, and the brackets 51 are fixedly connected to the connecting part. By providing the brackets 51, reliable fixation between the support base 5 and the cover 6 can be achieved.

[0045] Optionally, both the support base 5 and the bracket 51 are made of carbon steel. Carbon steel is an iron-carbon alloy with a carbon content between 0.0218% and 2.11%, also known as carbon steel. Its main components include elements such as iron, carbon, silicon, manganese, sulfur, and phosphorus. It possesses good strength, hardness, wear resistance, weldability, and machinability.

[0046] In this embodiment, the bracket 51 includes a first fixing part 511 and a second fixing part 512 that are L-shaped and bent. The first fixing part 511 is fixed to the support base 5, and the second fixing part 512 is fixed to the connecting part. Specifically, the first fixing part 511 can reliably abut against the support base 5 to achieve a fixed connection between the first fixing part 511 and the support base 5, and the second fixing part 512 can reliably abut against the connecting part to achieve a fixed connection between the second fixing part 512 and the cover 6.

[0047] In this embodiment, the first fixing part 511 and the second fixing part 512 are integrally bent and formed, which is convenient for processing.

[0048] Optionally, the connection between the bracket 51, the support base 5, and the cover 6 can be configured as a detachable connection. Specifically, the first fixing part 511 has a first connecting hole 5111, the second end of the wind shield 4 has a through hole 41, and the support base 5 has a first mounting hole 501. The first connecting hole 5111, the through hole 41, and the first mounting hole 501 are correspondingly arranged. The first bolt 71 passes through the first connecting hole 5111, the through hole 41, and the first mounting hole 501 in sequence and is then threadedly connected to the first nut 72, thereby achieving reliable fixation between the bracket 51, the wind shield 4, and the support base 5.

[0049] Optionally, the bracket 51, the first connecting hole 5111, and the first mounting hole 501 are provided in multiple corresponding positions.

[0050] The second fixing part 512 has a second connecting hole 5121, and the cover 6 has a corresponding second mounting hole (not shown). The second bolt (not shown) passes through the second connecting hole 5121 and the second mounting hole (not shown) and is threadedly connected to the second nut (not shown).

[0051] This embodiment is not limited thereto; the bracket 51, the support base 5, and the cover 6 can also be fixedly connected by means of snap-fit ​​or other methods.

[0052] Alternatively, the support base 5 and the wind shield 4 can also be connected by adhesive.

[0053] In this embodiment, the outer edge of the first end of the air shield 4 is provided with an inwardly inclined overlapping ring portion 42, which fits against the outer peripheral wall of the air guide 2. The overlapping ring portion 42, when the first end of the air shield 4 is fitted onto the air guide 2, can effectively fit against the outer peripheral wall of the air guide 2, thereby eliminating the gap between the air shield 4 and the air guide 2 and ensuring sealing.

[0054] In this embodiment, a sealing ring is provided between the air guide 2 and the heat sink 1. The sealing ring can effectively seal the gap between the air guide 2 and the heat sink 1, preventing hot airflow from flowing out from the gap between the air guide 2 and the heat sink 1. Optionally, the sealing ring is also made of rubber.

[0055] In this embodiment, the heat dissipation assembly also includes a protective mesh cover 31, which is disposed on the outside of the cooling fan 3 and is fixedly connected to the air guide cover 2. The protective mesh cover 31 can effectively protect the cooling fan 3, and the size and position of the flow holes opened on the protective mesh cover 31 can also guide the hot airflow to a certain extent.

[0056] In summary, the heat dissipation component provided in this embodiment, with the air shield 4, can effectively improve the exhaust rate of hot airflow, reduce the possibility of hot airflow flowing out from the guide gap, effectively reduce the degree of hot air recirculation, reduce the mixing of hot airflow rebounding at the air inlet of radiator 1, and reduce the air inlet temperature of radiator 1. When installed on an articulated dump truck, it can effectively reduce engine speed and reduce overall fuel consumption.

[0057] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
