Description

Technical Field

[0001] This utility model relates to the field of common rail cooling technology, and in particular to a common rail air-cooling device with adjustable air outlet height. Background Technology

[0002] Common rail, short for High-Pressure Common Rail System (HPCR), is a fuel injection technology used in internal combustion engines (primarily diesel engines, but also some gasoline engines). Its core feature is the unified delivery of high-pressure fuel to each injector via a common high-pressure fuel rail, enabling precise control of fuel injection pressure, timing, and quantity, thereby optimizing engine performance. Common rail materials are mostly 38MnVS6, with performance requirements of 265-320 HB, now demanded to reach 310-355 HB. Currently, the low cooling strength after forging and the inability to adjust the exhaust height fail to meet these requirements, making solutions crucial. Utility Model Content

[0003] In view of this, the purpose of this utility model is to propose a common rail air-cooling device with adjustable air outlet height, which solves the problems in the background art.

[0004] To achieve the above objectives, this utility model provides a common rail air-cooling device with adjustable air outlet height, comprising a conveyor, a fixed frame on one side of the top of the conveyor, and multiple snail-type fans distributed on both sides of the conveyor in the conveying direction. Each snail-type fan has an air outlet pipe at its top, which is bent and passes through the top of the fixed frame into the frame. Multiple air vents are movably arranged in the upper part of the fixed frame, with an air vent connecting the ends of every two oppositely arranged air outlet pipes. The air vents are fitted onto the ends of the air outlet pipes and slide to be raised and lowered. An adjusting valve is provided between the snail-type fans and the air outlet pipes.

[0005] Preferably, the top of the fixed frame is provided with a height adjustment mechanism, the bottom output end of the height adjustment mechanism is connected to a lifting plate, the bottom of the lifting plate is connected to two air outlet connecting plates, the air outlet is fixed to the bottom of the two air outlet connecting plates, and the end of the air outlet pipe slides through the air outlet connecting plate and the top of the air outlet to extend into the air outlet.

[0006] Preferably, the height adjustment mechanism includes a motor disposed on the top of the fixed frame, a gear disposed at the output end of the motor, the gear meshing with a lead screw, a threaded block fixedly disposed on the top of the fixed frame, the lead screw and the threaded block being threadedly connected, and the lead screw passing downward through the top of the fixed frame and connecting to the top of the lifting plate.

[0007] Preferably, the bottom end of the lead screw is rotatably connected to the lifting plate via a bearing.

[0008] Preferably, the air vent is funnel-shaped, narrow at the top and wide at the bottom.

[0009] Preferably, the fixing frame is door-shaped, and the fixing frame has openings on both sides in the conveying direction of the conveyor, with the air vents close to the openings.

[0010] The beneficial effects of this utility model are as follows: This utility model uses a common rail placed on a conveyor for transportation. Multiple snail-type fans are distributed on both sides of the conveyor's transport direction to provide a cooling source. The air outlet pipes of the snail-type fans extend through bends into a fixed frame at the top of the conveyor. This arrangement of multiple snail-type fans through the outlet pipes achieves high-intensity air cooling. An air vent is provided at the end of every two oppositely arranged air outlet pipes via a sliding sleeve. The height of the air vents can be adjusted to meet different needs. The vents are funnel-shaped to facilitate the diffusion of the converged cold air. The fixed frame is door-shaped with openings on both sides to facilitate rapid heat dissipation.

[0011] The top of the fixed frame is raised and lowered by a height adjustment mechanism, which in turn raises and lowers the air outlet connecting plate, thereby raising and lowering the air outlet. The air outlet and the air outlet connecting plate are slidably fitted onto the end of the air outlet pipe. The starting motor drives the gear to rotate, which in turn drives the lead screw to rotate. The lead screw rotates in the threaded block, thereby raising and lowering the air outlet. The bottom end of the lead screw is rotatably connected to the lifting plate, thereby raising and lowering the lifting plate. Attached Figure Description
