Description

Technical Field

[0001] The utility model relates to the technical field of equipment connectors, in particular to a 180-degree corner head structure. Background Art

[0002] In industrial machinery, exhaust heads are often used as pipe connectors for exhaust systems. Due to the limited size and internal components of industrial equipment, large-angle heads are often required to meet these requirements. However, large-angle heads, such as 180° heads, can lead to uneven flow velocity distribution at various locations within the head due to their angular characteristics. This can affect the exhaust efficiency of the head (resulting in poor heat dissipation), significantly impacting the performance of the industrial machinery.

[0003] Therefore, it is of great practical significance to develop a 180° corner head structure with uniform flow velocity distribution and high exhaust efficiency. Utility Model Content

[0004] Due to the above-mentioned defects in the existing technology, the utility model provides a 180° corner head structure with uniform flow rate distribution and high exhaust efficiency to solve the problem that the uneven flow rate distribution of the 180° corner head affects the exhaust efficiency of the head and thus affects the performance release of the equipment.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A 180° corner head structure, comprising a 180° elbow tubular structure;

[0007] One end of the elbow tubular structure is a head inlet, which is rectangular, and the other end is a head outlet, which is circular;

[0008] A plurality of outlet guide blocks are installed on the inner wall of the head outlet and are evenly distributed around the circumference of the head outlet. The angle between the arrangement direction of the outlet guide blocks and the axial direction of the head outlet is an acute angle.

[0009] The guide plate I, guide plate II and guide plate III are installed in the elbow tubular structure in sequence along the direction from the head inlet to the head outlet. The guide plate I is located on the bending side of the center line of the elbow tubular structure toward the elbow tubular structure, the guide plate II is located on the side of the elbow tubular structure away from the bending side of the center line of the elbow tubular structure, and the guide plate III is arranged at the maximum bending point of the elbow tubular structure and its center is located on the center line of the elbow tubular structure.

[0010] The 180° corner head structure of the utility model and the specific design of the guide plate I, guide plate II and guide plate III arranged in sequence in the elbow tubular structure can maximize the uniformity of airflow distribution at various locations in the elbow tubular structure, thereby improving its exhaust / intake efficiency; the multiple outlet guide blocks arranged at the head outlet can increase the airflow velocity at the outlet to a certain extent (the airflow will be spirally accelerated under the guidance of multiple outlet guide blocks), further improving the exhaust / intake efficiency of the overall structure, and has great application prospects.

[0011] As the preferred technical solution:

[0012] In the 180° corner head structure as described above, the thicknesses of the guide plates I, II and III gradually increase along the airflow direction.

[0013] In the 180° corner head structure as described above, the arrangement direction of the guide plate I is parallel to the center line of the elbow tubular structure here.

[0014] In the 180° corner head structure as described above, the angle formed by the guide plate II and the airflow direction of the center line of the elbow tubular structure is an acute angle.

[0015] In the 180° corner head structure as described above, the angle formed by the guide plate III and the airflow direction of the center line of the elbow tubular structure is an acute angle.

[0016] The above technical solution is only a feasible technical solution of the present invention. The protection scope of the present invention is not limited to this. Those skilled in the art can reasonably adjust the specific design according to actual needs.
