Description

Stone-strike prevention device, vehicle cooling module comprising same and vehicle

Technical Field

The utility model relates to a prevent stone and hit device for protecting vehicle cooling module particularly, relates to one kind and possesses the stone and hit device, including this vehicle cooling module who prevents the stone and hit the vehicle cooling module of device and including this vehicle cooling module of adjusting the amount of wind distribution between the vehicle cooling module when protecting vehicle cooling module.

Background

Automotive cooling modules generally refer to various heat exchanger combinations that dissipate heat from engines, air conditioners, turbochargers, and the like. Typically comprising a condenser, a radiator, an intercooler and a fan. The placement and performance of automotive cooling modules is very important to overall vehicle performance.

In a conventional automobile, because the engine room space is sufficient, the cooling module is mostly arranged in a sandwich manner. And each heat dissipation module is overlapped layer by layer and keeps a certain distance. The advantage of this arrangement is that the amount of air passing through each heat sink module is substantially proportional to the orthographic area of the heat sink module. The disadvantage is the large space requirement.

The current automobile model design is increasingly popular with a short front overhang trend, namely the distance from the grille to the arrangement point of the cooling module is greatly reduced compared with the traditional model. If a purely sandwich-type arrangement is still used, there is insufficient space. The countermeasure is that the cooling modules are arranged one above the other, i.e. each heat exchanger is reduced in size. The condenser and the radiator are then arranged above and the charge air cooler below. This arrangement has the advantage of being compact in space, but has the disadvantage of high air flow requirements for heat dissipation and uneven air flow requirements between each heat exchanger. In general, when the upper and lower grids are arranged, a stone-hit preventing device is added in a position in front of the intercooler to protect the intercooler from being hit by stones flying from the lower grid.

Detailed Description

It is easily understood that, according to the technical solution of the present invention, a plurality of alternative structural modes and implementation modes can be proposed by those skilled in the art without changing the spirit of the present invention. Therefore, the following detailed description and the accompanying drawings are merely illustrative of the technical solutions of the present invention, and should not be considered as limiting or restricting the technical solutions of the present invention in their entirety or in any other way.

The terms of orientation of up, down, left, right, front, back, top, bottom, and the like referred to or may be referred to in this specification are defined relative to the configuration shown in the drawings, and are relative terms, and thus may be changed correspondingly according to the position and the use state of the device. Therefore, these and other directional terms should not be construed as limiting terms. Furthermore, the terms "first," "second," "third," and the like are used for descriptive and descriptive purposes only and not for purposes of indication or implication as to the relative importance of the respective components.

Referring to fig. 1, a schematic view of the diversion of the stone-impact prevention device is shown. As shown, the vehicle cooling module includes a condenser, an intercooler, and a radiator, wherein the condenser and the radiator are disposed above the intercooler (disposed in a row side by side in the drawing), and the stone impact prevention device 100 is disposed in front of the intercooler. The stone-hit preventer 100 comprises a grill frame 1 through which an air flow can flow, a wind shield 2 obliquely disposed on an upper edge of the grill frame 1 for guiding the air flow in a direction of a condenser and a radiator, and fastening parts for fixing the stone-hit preventer 100 in front of an intercooler. When the automobile runs, the air flow facing the intercooler is divided into an upper part and a lower part by the wind shield 2, the upper air flow is guided to the condenser and the radiator, and the lower air flow flows through the grid frame 1 which is not shielded by the wind shield 2 and enters the intercooler. The air flow is thus distributed, e.g. relatively evenly distributed, between the charge air cooler and the condenser/radiator via the arrangement of the wind deflectors 2 as shown in the figure.

Referring to fig. 2 to 3, the stone impact prevention device 100 is rectangular, and fixing bayonets 4 (the fastening parts have the fixing bayonets) are formed at four corners of the stone impact prevention device 100, so that the stone impact prevention device 100 is snap-connected to an intercooler. It should be understood that "rectangular" is a shape representation in the general sense and does not represent that the stone impact prevention device 100 is a strictly rectangular shape, that is, the stone impact prevention device 100 can have a slight modification on the basis of a rectangle, such as features of a turned-up edge, a protruding portion, a recessed portion, a bent portion, an opening, a chamfer, etc., as long as it is generally rectangular. A snap is a mechanism for the embedded connection or integral locking of one part to another. The buckle connection has the biggest characteristic that the buckle connection is convenient to mount and dismount and can be dismounted without tools, so that the assembling efficiency is high, the assembling process of the buckle position is simple, generally only one inserted action is needed, the action of rotating motion or positioning a product before assembly is not needed, and a simple and rapid assembling effect is achieved.

Further, hooks 5 (the fastening members have the hooks 5) extending in the intercooler direction are provided at the centers of the upper and lower edges of the grille frame 1, respectively, for hooking the intercooler with respect to the vehicle traveling direction, so that the fixing of the stone impact preventing device 100 can be ensured in cooperation with the fixing bayonets 4. The grille strips in the grille frame 1 of the stone-strike protection device 100 are arranged horizontally for horizontal laminar airflow, it being understood that other arrangements are possible, such as vertical arrangements, inclined arrangements, and even arrangements with intersecting, curved, serpentine, etc. grille strips, depending on the circumstances. In addition, the spacing between the grid bars is 5-7mm, for example 6mm, as determined by intercooler tests.

The angle of inclination of the wind deflector 2 relative to the grille frame 1 will determine the effectiveness of the airflow directed into the upper condenser/radiator, i.e. both too large and too small angles will affect the air distribution. When the wind deflector 2 and the grid frame 1 form an angle of 50-70 degrees, the air quantity is distributed in a larger range. The wind shield 2 and the grating frame 1 form an angle of 60 degrees through detailed simulation calculation, and the air distribution effect is best. On the other hand, the height of the wind shield 2 will determine the area of the wind shield 2 covering the grille frame 1, i.e. the intake of the intercooler itself. After testing the heights of 10mm, 20mm, 30mm and 40mm respectively, it is found that the effect of the distribution of the upper and lower airflows is the best when the height of the wind deflector 2 is 30 mm.

According to another aspect of the present invention, there is also provided a vehicle cooling module comprising a condenser and a radiator arranged above and an intercooler arranged below the condenser and the radiator, wherein the vehicle cooling module further comprises any of the above-mentioned stone-impact prevention devices 100 arranged in front of the intercooler. Furthermore, the utility model discloses a vehicle cooling module still can install on various vehicles, including gasoline car, diesel vehicle, car, freight train, passenger train, hybrid vehicle, pure electric vehicles and so on. Accordingly, the subject matter of the present invention is also directed to protecting various vehicles equipped with the vehicle cooling module of the present invention.

It should be understood that all of the above preferred embodiments are exemplary and not restrictive, and that various modifications and changes in the specific embodiments described above, which may occur to those skilled in the art upon reading the teachings of the present invention, are intended to be within the scope of the appended claims.
