Thus, the following features, embodiments, and advantages are merely illustrative and should not be considered elements or limitations of the claims except where explicitly set out in a claim.

The terms "comprising" and "having" are used in the following to mean that there are open-ended, including, and that there may be additional elements/components in addition to the listed elements/components.

FIG. 1 is an exploded view of a cowl assembly according to an embodiment of the present utility model. The illustrated wind scooper assembly 1 is of a split type, comprising a wind scooper 11 and a sealing ring 12 that can be detachably connected to the wind scooper 11. The wall of the air guide housing is provided with a through hole 110 for placing a fan (not shown). The central axis of the fan is arranged coaxially with the central axis of the through hole.

As shown in connection with fig. 1 and 4, the periphery of the through-hole 110 is provided with mounting features. The mounting features on the wind scooper are embodied as bosses 111 provided on the outer side of the housing wall. In the embodiment shown in fig. 1 and 4, the boss 111 includes four arc-shaped ribs arranged at intervals along the circumferential direction of the through hole. Although four ribs are shown in the figures, it will be appreciated that the boss could be formed to include a number of rib sections other than 4, or as a single annular rib. The boss may also be provided on the inner side of the shroud wall in the peripheral region of the through-hole. Alternatively, the cover wall may be provided with protrusions on both the inner and outer sides. The bosses on the inner and outer sides may have different arrangements and configurations.

The boss 111 may be attached to the mask wall by an attachment method such as bonding or welding or may be integrally formed with the mask wall. For example, the boss is formed by punching on the cover wall.

Referring to fig. 2A, 2B and 3, the seal ring 12 includes a coupling portion 121 for detachably coupling to the periphery of the through hole of the wind scooper. The coupling portion 121 has a mating feature for mating with a mounting feature provided on the periphery of the through hole of the wind scooper to form a snap-lock. In the embodiment shown in fig. 2B, the mating feature is configured to include an engagement groove 121g for engagement with the boss 111. The engagement groove 121g opens toward the planar side of the hood wall to engage with the boss 111 protruding from the planar side of the hood wall.

The joint 121 of the seal ring 12 may further comprise two oppositely disposed clamping legs 121c for clamping the cap wall and the boss in an interference fit. The engagement groove 121g may be provided directly on the side of the grip leg 121c facing the hood wall. In the embodiment shown in fig. 2B and 3, the engagement grooves 121g are provided on both the clamp legs 121c. In the advantageous embodiment shown, the two engagement grooves provided on the clamping legs merge in the crotch region between the clamping legs into one groove/recess extending astride the periphery of the through hole. As shown in fig. 2B and 3, the cross section of the concavity tapers in a radially outward direction, thereby forming a large concave space for the calf. With this configuration, the type of mounting feature of the air guide housing that is adapted to the seal ring can be increased. The mounting features on the wind scooper are arranged on one side or both sides of the wall of the wind scooper during mounting, so that the mounting steps can be simplified. It will also be appreciated by those skilled in the art that when a boss is provided on only one side of the shroud wall, a corresponding engagement recess may also be provided on only the clamping leg facing the boss.

In the embodiment shown in fig. 2B and 3, the coupling portion 121 further includes a guide portion 121p provided at the distal end of the clamp leg 121c for guiding the boss 111 into engagement with the engagement groove 121g. During the process of installing the seal ring on the wind scooper, the guide parts 121p slide outwards from the periphery of the through hole on both sides of the wall, and on the side of the wall where the protruding parts are arranged, the protruding parts 111 form sliding abutting contact with the corresponding guide parts 121 p. As the guide portion slides radially outward, the guide portion sweeps over the boss, and the engagement groove 121g of the engaging portion slides anteriorly to an engaged position with the boss, obtaining a form-fit between the boss and the engagement groove. To ensure the positive-locking securement, the clamping leg 121c may include a castellated barb 121ch extending from the clamping leg body toward the hood wall side, the castellated barb defining a stop wall radially outward of the engagement groove 121g. The tooth-shaped barb portion is engaged into a concave space formed between the radially outer side surface of the boss and the corresponding shroud wall side surface, effectively preventing the lock between the engagement groove 121g and the boss 111 from being released by the radially inward tensile force. The crotch portion of the joint between the clamping legs serves to block the release of the locking connection under radially outward pulling forces. The two clamping legs clamp the cover wall with the protruding parts from the two sides of the cover wall through interference fit. Thus, a firm snap connection is formed between the joint 121 of the sealing ring 12 and the mantle wall.

In the embodiment shown in fig. 2B, the engagement groove 121g is formed as an annular groove. With this configuration, as long as the engaging groove is in a position corresponding to the boss in the radial direction of the seal ring 12, the boss and the engaging groove can be engaged to obtain a sufficiently strong form-locking irrespective of the circumferential positioning of the engaging groove with respect to the boss. Of course, the engagement groove may be formed to include a plurality of arcuate groove segments arranged at intervals in the circumferential direction of the seal ring. The arcuate slot segments can be circumferentially aligned with correspondingly configured arcuate ribs by suitable positioning means to ensure engagement therebetween.

Referring to fig. 2B and 3, the seal ring 12 according to the present utility model further includes a rim portion 122 extending from the joint portion 121 toward the fan blade tip and extending axially along the seal ring to define a flow-guiding vent. The vents of the flow-guiding type are aerodynamically, e.g. configured as a bell-mouth, advantageously guiding the airflow into or out of the fan, effectively improving the working efficiency of the fan while reducing the gap between the fan and the air guiding cover.

In an advantageous embodiment, the sealing ring 12 is made of an elastomeric material, such as rubber, silicone, etc. Therefore, the sealing ring can be integrally formed through injection molding, and the production efficiency is greatly improved. In addition, due to the inherent elasticity of the elastomeric material, the joint of the seal ring can be easily assembled to the cover wall by slightly elastic deformation without causing excessive stress inside the seal ring. Even in the case of a large mounting error, the frame portion 122 of the seal ring closest to the fan blade does not cause hard damage to the fan blade due to the presence of elasticity.

In an advantageous embodiment, the sealing ring, which is mainly made of an elastomer material, is embedded with a metal reinforcement at least in the region of the joint. The metal reinforcement embedded in the joint region can avoid the problems of internal tearing, integrity reduction and locking strength reduction of the joint caused by deformation in the installation process, improves the durability of the sealing ring and prolongs the service life. In addition, the elastic reaction force generated by the structural deformation of the metal reinforcing part is utilized to improve the clamping force and the locking force on the cover wall, so that the problems of aging, damage and falling of the elastic body caused by long-term use are avoided.

In addition, in order to facilitate the disassembly and to avoid damage or wear to the joint 121 of the seal ring 12 during the disassembly, the surface of the boss for abutment with the joint of the seal ring is advantageously configured as an arcuate curved surface.

In this context, the term "radial" refers to a direction towards the periphery of the through-hole with respect to the center of the through-hole/seal ring. The term "circumferential" refers to a direction around the center of the through hole/seal ring. The term "inside" refers to the side of the hood wall facing the interior space thereof, and the term "outside" refers to the side of the hood wall exposed to the outside. The term "via periphery" refers to an area around the periphery of a via, including the edge of the via opening as well as an area adjacent to the edge of the via opening.

Although in the embodiment shown in fig. 1-4 the mounting feature provided on the wind scooper is a protrusion, as a variant the mounting feature may also be designed as a groove, and correspondingly the mating feature in the joint of the sealing ring for mating with the mounting feature may be designed as a protrusion. The protrusions are placed in the position where they are engaged with the grooves under the guiding action of the guide portions, and furthermore, by means of interference engagement between the clamping legs and the hood wall, the strength of the connection between the seal ring and the hood wall is additionally enhanced by the reaction force generated by the deformation of the clamping legs, whereby the seal ring is firmly attached to the hood. Alternatively, in the case of a groove-shaped mounting feature designed as an arcuate groove segment, the sealing ring, in which the joint overlaps the periphery of the through-opening in the cover wall, can be rotated so that the corresponding mating feature designed as an arcuate rib slides from the groove segment end side into the arcuate groove segment and forms a lock therewith. Therefore, the mounting features and mating features of the present utility model are not limited to the specific forms presented in the illustrated embodiments.

The radiator assembly comprises a radiator, a fan for the radiator and the wind scooper component for the fan for the radiator. Thus, by means of the wind scooper assembly according to the present utility model, a radiator assembly having improved heat radiation performance can be efficiently provided at low installation cost.

Industrial applicability

In order to better understand the present utility model, a specific assembly process of the seal ring of the present utility model will be described below by taking the assembly structure between the seal ring and the air guide housing shown in fig. 3 as an example.

Corresponding matching sealing rings 12 are provided depending on the specific arrangement of mounting features at the periphery of the through holes of the wind scooper.

The joint portion 121 of the seal ring 12 is straddled on the inner periphery of the through hole such that one of the clamping legs 121c and the guide portion 121p is located on the inner side of the cover wall and the other clamping leg 121c and the guide portion 121p is located on the outer side of the cover wall. The crotch portion between the clamping legs spans the through hole edge. At this time, since the sum of thicknesses between the cover wall and the boss is larger than the distance between the guide portions, the guide portions are deformed, and as the engaging portion 121 is pushed in the radially outward direction, the guide portions 121p are correspondingly slid in the radially outward direction, and the portions where the deformation of the guide portions is the greatest are also displaced in the direction of the clamp legs. The tooth-shaped barb 121ch provided on the grip leg 121c slides over the boss in a compressed state under the guiding action of the guide portion. The boss 111 is also moved relatively deeper into the engagement groove 121g, the tooth-shaped barb portion sliding over the boss is deformed from a compressed state to an extended state, and is snapped into the corner space defined by the radially outer side of the boss and the side face of the hood wall, at this time, the boss 111 is also moved completely into engagement with the engagement groove 121g, and since the clamp leg 121c is brought into interference fit with the hood wall with the boss, an abutting contact is formed between the clamp leg and the boss, and the end of the clamp leg and the guide portion still clamp the hood wall from both sides of the hood wall. The friction fit produced by the interference fit and the snap fit produced between the projection and the engagement recess thus double stiffen the connection strength between the sealing ring and the cap wall. The only assembly force required is the deformation force required to overcome the interference fit throughout the installation process. Therefore, the installation process is easy and convenient.

When the joint 121 is installed in place, the rim portion 122 of the sealing ring is correspondingly in place, and the entire streamlined vent is also in place. The radial width dimension of the boss 111 and its radial position on the shroud wall also ensures radial spacing of the seal ring vent from the fan blade tip, thus enabling accurate and efficient reduction of clearances around the fan and improved fan operating efficiency. Integration of the streamline structure on the sealing ring improves the working efficiency of the fan and simultaneously improves the assembly efficiency.

Besides the improvement of the assembly efficiency, the utility model also allows for a convenient and quick disassembly of the sealing ring, since the disassembly of the sealing ring only requires the application of sufficient force to release the interference fit between the clamping legs and the cover wall, and the disappearance of the interference fit also releases the engagement between the protrusions and the engagement grooves.

The air scoop assembly according to the present utility model may be used in all work machines that require cooling of a radiator by a fan to achieve the desired work and operation.
