Radiator shutter for construction machines

Abstract

The utility model relates to a heat dissipation door plate for engineering machinery, including door plate outer frame and mesh plate. The outer frame is high in strength, constitutes the appearance skeleton of door plate, the mesh plate in the middle is covered with large-area mesh to realize heat exchange function, and can avoid the entry of foreign matters such as stone, flying insects into the inside of engineering machinery, but the mesh plate has no strength and cannot be used alone. The outer frame and mesh can be made on the same steel plate, but the shortcoming of this processing method is not only low processing efficiency, but also the dislocation of mesh during processing, which forms waste products. The utility model is to process the outer frame and mesh plate separately, which can greatly reduce the manufacturing cost.

Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, specifically to a heat dissipation door panel for engineering machinery. Background Technology

[0002] Construction machinery is equipped with engines, and these engines are fitted with external cooling vents and topped with engine hoods. These vents and hoods serve not only a protective function but also a cooling function to prevent engine overheating. The cooling vents can be simply understood as a kind of "screen door"—they allow ventilation while also having sufficient strength to prevent stones and other debris from entering. The design principle is to maximize the open area ratio, that is, to increase the area occupied by the mesh to facilitate ventilation and heat dissipation. To achieve this high open area ratio, the mesh plates are typically very densely perforated. Figure 1 In the existing technology, holes are punched directly on the heat sink door panel. However, the punching process of the door panel frame and the mesh holes on the same plate is relatively complicated. It not only takes a long time to process, but also makes it very easy to scrap the entire door panel due to misalignment of the hole spacing. Summary of the Invention

[0003] To overcome existing problems, this utility model provides a heat dissipation door panel for engineering machinery, comprising: a door panel outer frame, connected to the body of the engineering machinery via hinges and a door lock; and The perforated plate includes a connecting part, a bending part, and a ventilation part connected in sequence. The connecting part, the bending part, and the ventilation part are integrally formed and each has multiple ventilation holes. The outer frame of the door panel is located outside the connecting part and connected to the connecting part. The dimension of the break height of the bending part is the same as the dimension of the thickness of the outer frame of the door panel, so that the outer surface of the perforated plate is flush with the outer surface of the outer frame of the door panel. The ventilation part is used for heat dissipation of the engine inside the engine hood.

[0004] Optionally, the inner side of the door panel outer frame is welded or bonded to the outer side of the connecting part.

[0005] Optionally, the ventilation holes are arranged regularly along the horizontal direction, vertical direction, or at a certain angle on the perforated plate.

[0006] Optionally, the ventilation hole is a round hole, a square hole, or a polygonal hole.

[0007] The technical solutions provided by the embodiments of this utility model may include the following beneficial effects: By embedding a perforated panel with a discontinuous structure into the door panel, the entire outer surface of the door panel can be made smooth. Moreover, because the perforated panel and the door panel are manufactured separately, different materials and panel thicknesses can be selected, providing possibilities for flexible design.

[0008] Furthermore, the height difference of the bend is the same as the thickness of the door panel frame, and the door panel frame and the ventilation section are flush in the horizontal direction, which prevents the upper and lower edges of the door panel frame from rusting due to rain accumulation, and is also more aesthetically pleasing.

[0012] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0013] In this invention, unless otherwise stated, directional terms such as "upper," "lower," "front," "rear," "left," and "right" are used for ease of description based on the drawing directions in the corresponding figures, while "inner" and "outer" are defined based on the contours of the corresponding components themselves. Terms such as "first" and "second" used in this invention are used to distinguish one element from another and do not have sequential or importance implications. Furthermore, when the following description refers to the figures, unless otherwise indicated, the same numbers in different figures represent the same or similar elements.

[0014] Please see Figure 2 This utility model provides a heat dissipation door panel for construction machinery, including a door panel frame 11 and a perforated plate. The door panel frame 11 is connected to the construction machinery body via hinges and a door lock. The perforated plate includes a connecting part 21, a bending part 22, and a ventilation part 23 connected in sequence. The connecting part 21, the bending part 22, and the ventilation part 23 are integrally formed and each has multiple ventilation holes 24. The door panel frame 11 is located outside the connecting part 21 and connected to it. The height difference of the bending part 22 is the same as the thickness of the door panel frame 11, making the outer surface of the perforated plate flush with the outer surface of the door panel frame 11. The ventilation part 23 is used for heat dissipation of the engine inside the engine hood.

[0015] Understandably, the new process can produce perforated panels and door frames separately. The perforated panels are punched with a gantry punching machine at high speed to create the mesh holes 24, then the outer contour of the connecting part 21 is cut out with a laser cutting machine, and then the bending part 22 is made with a break forming die. This process is not only fast but also has a high yield. The door panels are processed with a laser cutting machine and then shaped by bending or other processes.

[0016] Furthermore, the dimension of the break height of the bending part 22 is the same as the dimension of the thickness of the door panel outer frame 11, and the door panel outer frame 11 and the ventilation part 23 are flush in the horizontal direction, which prevents the lower frame of the door panel outer frame 11 from rusting due to rain accumulation.

[0017] In one embodiment, the inner side of the door panel outer frame 11 is welded or bonded to the outer side of the connecting part 21.

[0018] In one embodiment, ventilation holes 24 are arranged regularly along the horizontal direction, vertical direction, or at a certain angle on the perforated plate.

[0019] In one embodiment, the ventilation holes 24 are round, square, or polygonal holes, and are arranged as closely as possible to achieve the largest possible opening ratio and improve heat dissipation efficiency.

[0020] This invention has been described through embodiments. Those skilled in the art will understand that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the invention. Furthermore, under the teachings of this invention, modifications can be made to these features and embodiments to adapt to specific situations and materials without departing from the spirit and scope of the invention. Therefore, this invention is not limited to the specific embodiments of the utility model described herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this invention.
