The flow regulating structure comprises a plurality of rail structures. Each rail structure has a plurality of rod-shaped members that are arranged side-by-side with the same direction of extension. The plurality of rail structures are disposed along the direction of gas travel in overlapping positions with space therebetween. The extension directions of the rod-shaped members differ between adjacent rail structures. In each rail structure, the plurality of rod-shaped members are arranged side-by-side with the same direction of extension in both a first virtual plane and a second virtual plane, which face one another in the direction of gas travel, and when viewed from the direction of gas travel, the rod-shaped members disposed on the second virtual plane are positioned between adjacent members among the plurality of rod-shaped members disposed on the first virtual plane.

Apparatus for tensioning pliable airducts while supporting internal HVAC components are disclosed. An airduct system includes an airduct having an elongate tubular wall of a pliable material. The airduct system further includes a frame disposable inside the tubular wall of the airduct, the frame including a hoop to support the tubular wall in a radial direction, the hoop to define an opening to provide passage of a flow of air along a length of the airduct. The airduct system also includes an HVAC component disposable within the tubular wall of the airduct, the HVAC component to be attached to and supported by the frame inside the airduct, the HVAC component to adjust a characteristic of the air.

A heat transfer tube includes a twisted baffle arranged in an inner wall of the tube. The twisted baffle extends spirally along an axial direction of the heat transfer tube. The twisted baffle is provided with a non-through gap extending along an axial direction of the heat transfer tube from an end to the other end of the twisted baffle. A cracking furnace uses the heat transfer tube. The heat transfer tube and cracking furnace have good heat transfer effects and small pressure loss.

A wheel spoiler arrangement, encompassing: a wheel spoiler carrier; a wheel spoiler received displaceably relative to the wheel spoiler carrier between inactive and active positions constituting operating positions; a motion guidance system between the carrier and the spoiler, a drive system to drive the spoiler between its operating positions, and an overload coupling that transfers force in a direction from the spoiler to the drive system up to a predetermined limit load; the overload coupling having a shiftable structure that is shiftable, between an effective position into which the structure is preloaded in a force-transferring engagement and a passive position in which position the force-transferring engagement is not possible; the shiftable structure being shiftable from the effective position into the passive position upon exceedance of the limit load resulting from a force acting on the spoiler.

Disclosed fluid flow modifying devices are useful with flexible fluid flow conduits. Such devices are adapted for mitigating adverse flow considerations arising from one or more bends in flexible fluid flow conduits. These adverse flow considerations are generally characterized as enhanced laminar flow and associated increased backpressure arising from reduced flow velocity caused by the one or more bends. Beneficially, disclosed fluid flow modifying devices cause flow of flowable material (e.g., a liquid) within a flow passage of a fluid flow conduit to have a rotational flow profile. Such a rotational flow profile advantageously reduces frictional losses associated with laminar flow and with directional change of fluid flow.

The airduct system further includes a frame disposable inside the tubular wall of the airduct, the frame including a hoop to support the tubular wall in a radial direction, the hoop to define an opening to provide passage of a flow of air along a length of the airduct. The airduct system also includes an HVAC component disposable within the tubular wall of the airduct, the HVAC component to be attached to and supported by the frame inside the airduct, the HVAC component to adjust a characteristic of the air.

The disclosure provides an airflow regulation and control apparatus. A ventilation hole (11) is formed in a windshield (1) in a penetrating manner; a guide rail gate disc (2) is mounted on the windshield (1); the guide rail gate disc (2) is lifted by means of power provided by a lifting wing (3) disposed thereon, and the height of the guide rail gate disc (2) when moving upwards exceed the height of an upper edge of a main body portion of the windshield (1); when wind strength is low, the guide rail gate disc (2) is located at a lower portion under the action of gravity and shields the ventilation hole (11); when the wind strength is increased, the lifting wing (3) is blown by airflow to generate upwards lifting force, and drives the guide rail gate disc (2) to upwards move so as to shield an upper portion of the windshield (1) and block the airflow; and after part of the airflow blows to the windshield (1) through the ventilation hole (11), the excess airflow flows through the upper portion and both sides of a whole board surface defined by the windshield (1) and the guide rail gate disc (2). By blocking part of the airflow and reducing the airflow blowing to the rear of the windshield (1), more airflow is transferred to other positions, the airflow is better distributed, and the airflow meets the requirements of various components for the cooling airflow, so that an effect of reducing energy consumption is achieved.

A passive flow divider for providing outflows is described. The passive flow divider includes at least one inlet for an inflow and a plurality of outlets for said outflows, a housing enclosing a main partition that separates an intake space and a discharge space, a common end located at an interface between the intake space and the discharge space, and a baffle arranged in the intake space between said inlet and the common end. The passive flow divider further includes a plurality of distribution chambers arranged in the discharge space and adjacent to each other, each distribution chamber being arranged to lead an outflow from the common end to one of the outlets.

An embodiment provides A flow straightener, comprising; a conical-shaped portion having a first end and a second end substantially opposite the first end, wherein the first end has a bigger diameter than the second end; and a plurality of liquid directing vanes extending from the conical-shaped portion, wherein each of the plurality of liquid directing vanes are located at a different location on the conical-shaped portion and are oriented parallel to a longitudinal center axis of the conical-shaped portion; and wherein the plurality of liquid directing vanes extend from the conical-shaped portion such that the plurality of liquid directing vanes are located on either an upper half with respect to a horizontal centerline of an end the conical-shaped portion or a lower half with respect to the horizontal centerline of the conical-shaped portion; wherein each of the plurality of liquid directing vanes are shaped having a tapered tail located after the first end of the conical-shaped portion.
