Description

Technical Field

[0002] Some equipment is equipped with a ventilation baffle, which can be displaced when needed to open the air inlet to form an air flow channel. For example, a ventilation baffle can be set near the air intake grille at the front end of a vehicle. Under normal conditions, the air intake leading to the interior of the vehicle is generally closed by the ventilation baffle. When the vehicle is driving, air flow movement will be generated, and the air flow entering through the air intake grille will push the ventilation baffle and open the air intake, so that the air flow enters the interior of the vehicle for heat dissipation and cooling purposes.

[0003] The present application finds that there are still some areas for optimization and improvement in the existing ventilation baffles in terms of structural construction, performance, installation and manufacturing. For example, in combination with the above examples, when the vehicle is traveling at high speed or the external wind force is strong, the existing ventilation baffles will encounter great wind resistance, which may produce unexpected sharp noises and transmit them into the vehicle, affecting the driving comfort. In addition, the ventilation baffles will also be subjected to strong wind force and are easily damaged in structure, and good ventilation and safety protection cannot be guaranteed, and it is difficult to work stably and reliably for a long time.

[0026] It should be noted that the following will illustrate the structural composition, features and advantages of the ventilation baffle, heat exchange device and vehicle according to the present application by way of example, but all descriptions shall not be used to form any limitation on the present application. In order to simplify the drawings, the same or similar parts and features may be marked in only one or several places in the same drawing.

[0027] refer to Figures 1 to 5In these drawings, the general structure of several ventilation baffle embodiments according to the present application and the situations in which they disturb the airflow passing through are shown by way of example. The present application scheme will be described in detail below through these specific embodiments.

[0028] First, if Figure 1 and Figure 3 As shown, the ventilation baffle 10 can be configured to have an assembly portion 11 and a spoiler portion 12. The assembly portion 11 is configured to be used to install the ventilation baffle 10 at a position set according to application requirements, for example, Figure 1 As shown in the figure, the assembly part 11 is optionally arranged on the upper part of the ventilation baffle 10 and is configured to have a perforation 111. When the ventilation baffle 10 is installed, the shaft can be passed through the perforation 111, and the two ends of the shaft extending out of the perforation 111 are fixed to the preset positions (such as the assembly holes on the equipment housing, the slots on the on-site bracket, etc.). After the ventilation baffle 10 is installed in place, it can pivot around the shaft. Generally speaking, under normal conditions, the air inlet can be closed by the installed ventilation baffle 10, so that dust and debris from the outside can be prevented from entering the interior of the equipment space, thereby providing good protection. When encountering the action of airflow from the outside and having a certain flow rate, the ventilation baffle 10 will be activated to pivot, so that the previously closed air inlet can be opened to achieve ventilation, so that the airflow can flow through the ventilation baffle 10 through the air inlet, and then enter the interior of the equipment space, so as to be used for the desired possible operation, such as using the inflowing airflow to cool and reduce the temperature of the equipment, environmental space, etc.

[0029] According to different application requirements, the ventilation baffle 10 can be made of any one or more suitable materials such as plastic, metal, wood, etc., and can be designed to be a suitable shape structure such as a plate shape that meets the application requirements. According to the actual use occasion, by selecting and configuring the structure, material, weight, etc. of the ventilation baffle 10, it can be used to adapt to the airflow conditions that can prompt the ventilation baffle 10 to pivot, that is, only under the desired appropriate airflow, can the ventilation baffle 10 be prompted to pivot and open the previously closed air inlet.

[0030] In the ventilation baffle 10, the spoiler 12 is arranged on the outer surface 13 facing the airflow side, that is, located on the windward side of the ventilation baffle 10. The spoiler 12 can be used to disturb the airflow passing through the ventilation baffle 10, thereby forming an airflow disturbance zone 14. Figure 2 , Figure 4 and Figure 5 Multiple arrows have been used to schematically illustrate the flow direction and path of the airflow in such an airflow disturbance area.

[0031] By means of the disturbing effect of the spoiler 12 on the airflow, in particular by guiding the airflow to flow in the airflow disturbance area 14, for example Figure 2 The flow effects such as multiple crossovers and continuous mixing of airflows shown in the example can effectively reduce the impact of airflow on the ventilation baffle 10, and avoid the ventilation baffle being easily damaged due to long-term exposure to large forces. In addition, it can significantly reduce or even eliminate the abnormal noise commonly seen in existing ventilation baffles, which often manifests as sharp whistling sounds and is particularly likely to cause discomfort to people. The use of the ventilation baffle according to the present application can successfully solve the above problems.

[0032] As an optional situation, the spoiler 12 and the body of the ventilation baffle 10 can be formed in one piece, for example, by injection molding or casting, machining (such as stamping), etc. Of course, in some embodiments, the spoiler 12 can be installed at a suitable position on the ventilation baffle 10 by means such as gluing or welding.

[0033] As disclosed in the present application, the spoiler 12 can be configured as one or more protrusions 120 protruding outward from the outer surface 13 of the ventilation baffle 10. Through such a protrusion structure, part or all of the airflow in the airflow can form the above-mentioned airflow disturbance zone 14 when flowing through the outer contour of the protrusion. In addition, by providing the protrusion 120, the mechanical properties of the ventilation baffle 10 can be effectively improved, such as improving rigidity and mechanical strength. According to the needs of different application scenarios, the structure, size, number, arrangement position and other aspects of the protrusion 120 can be flexibly configured, for example, these protrusions are allowed to have the same or different structures.

[0034] For example, in Figure 1 In an embodiment, the protrusion 120 may be configured as one or more curved structures. When two or more curved structures are arranged, they may be arranged at intervals from each other, so as to form a channel for airflow between adjacent curved structures. In one or more embodiments, the curved structures may be arranged to extend along the longitudinal direction Y of the ventilation baffle 10 and to form a pair arrangement in the transverse direction X of the ventilation baffle 10, for example, Figure 1 The embodiment specifically shows that six pairs of curved structures are configured at this time. As a more specific example, each pair of curved structures can be arranged symmetrically about the longitudinal center line between them, and each pair of curved structures can be used to define the inlet 121 and the outlet 122, that is, when the airflow flows through the ventilation baffle 10, it can flow into the flow space defined by the pair of curved structures through the inlet 121, and then flow out from the outlet 122 and enter the internal space of the device. Of course, the flow path for the airflow to flow through can also be formed between two adjacent pairs of curved structures, which has the same or similar airflow disturbance effect.

[0035] It should be understood that the present application allows the curved structure to be configured into any feasible structural configuration as required. For example, in one or more embodiments, a plurality of crests 123 and a plurality of troughs 124 may be provided on the curved arc formed by the curved structure. Figure 1 As an optional case, the upper section of the curved structure closer to the assembly portion 11 can have a different wavelength (for example, longer or shorter) than the lower section of the assembly portion 11, thereby forming a distinctive structure, which will be conducive to better guiding the disturbed flow of the airflow at the ventilation baffle, promoting the formation of a more significant airflow disturbance effect, thereby reducing the impact of the airflow, reducing or avoiding the generation of abnormal airflow noise, etc.

[0036] Combined with reference Figure 3 , Figure 4 and Figure 5 In one or more embodiments, the protrusions 120 can be arranged into polygonal structures arranged at intervals from each other, such as triangles, quadrilaterals, pentagons, etc., so that the polygonal structure can be configured separately on the ventilation baffle, or can be combined with the above-mentioned curved structure or other suitable structures and arranged on the ventilation baffle at the same time.

[0037] As an optional situation, the polygonal structures used as protrusions 120 can be arranged in an array, that is, they can be arranged along the horizontal X and longitudinal Y of the ventilation baffle 10, and the specific number of arrangements can be designed as needed. In this way, when the airflow flows through the array of these polygonal structures, many airflow disturbance areas will be formed, prompting the airflow to form cross-mixing flows, etc., and produce obvious airflow disturbance effects. In some applications, it is beneficial to configure the outer contour of the polygonal structure to be a smooth transition, so that this can eliminate the undesirable whistling sound generated by the airflow encountering sharp parts when flowing, thereby further promoting the reduction of abnormal airflow noise, etc.

[0038] According to the scheme of the present application, a heat exchange device is also provided, in which one or more ventilation baffles designed according to the present application can be configured according to application requirements. The ventilation baffles can bring about outstanding technical effects that are significantly better than the prior art as described above.

[0039] As an example, see, for example, Figure 6 A specific example of a heat exchange device is given, and the heat exchange device 100 can be used as a vehicle front cooling device. Specifically, the vehicle front cooling device can be equipped with a ventilation baffle, which can be installed at the air flow inlet 110 of the vehicle front cooling device, and when in use, the vehicle front cooling device is installed on the vehicle and the ventilation baffle is adjacent to the air intake grille set at the front end of the vehicle, so that the ventilation baffle is actuated to pivot by the air flow flowing into the air intake grille during the driving of the vehicle, thereby opening the air intake so that the air flow can flow along, for example, Figure 6 The air flows in the direction indicated by the middle arrow through the vehicle front end cooling device 100 and then flows into the interior of the vehicle through the air flow outlet 130 of the vehicle front end cooling device. The air flow can be used to exchange heat with one or more devices on the vehicle (such as a vehicle air-conditioning device, etc.), thereby enabling the above-mentioned devices to achieve cooling, heat dissipation and other effects.

[0040] It is understandable that in addition to the present ventilation baffle, technicians in this field may consider configuring any suitable components for heat exchange devices such as vehicle front-end cooling devices according to the needs of specific applications, such as fans, radiators, condensers, filters, sensors, controllers, etc., which will not be discussed in this article.

[0041] The present application further provides a vehicle in which the vehicle front end cooling device provided by the present application can be configured and used according to actual application needs. It should be understood that the vehicle according to the present application has a wide range of types, for example, including but not limited to fuel vehicles, pure electric vehicles, hybrid vehicles, and many other types.

These examples are only used to illustrate the principle and implementation method of the present application, and do not constitute a limitation on the present application. Those skilled in the art may make various modifications and improvements without departing from the scope of the present application. Therefore, all equivalent technical solutions shall belong to the scope of the present application and be defined by the claims of the present application.
