Description

Technical Field

[0001] This application relates to the technical field of automotive air conditioning components, and particularly to an automotive cooling fan assembly. Background Art

[0002] The fan of an automobile is mainly used to drive air to generate an air flow and take away the heat on the air conditioner radiator. Since the central position of the fan is fixed, the range of the air flow generated by the fan blades is basically fixed. In order to enable the radiator to have a high heat dissipation efficiency, it is necessary to have air flow passing through all parts of the radiator, which requires the fan to have a relatively large fan blade diameter. Therefore, the volume of existing automotive cooling fans is generally not small. Utility Model Content

[0003] The purpose of this application is to provide an automotive cooling fan assembly with a smaller volume.

[0004] To achieve the above purpose, this application provides an automotive cooling fan assembly: including a longitudinal flow window, one open end of the longitudinal flow window is fixedly connected to a transverse flow window, and the other open end is fixedly connected to a drive window. The transverse flow window has a number of transverse guide plates extending horizontally. The rear side edges of these transverse guide plates are evenly spaced, and the spacing between the front side edges gradually increases from the middle to the upper and lower directions. The minimum spacing between the front side edges of the transverse guide plates is greater than or equal to the spacing between the rear side edges. A transverse diffuser channel is formed between adjacent transverse guide plates; the longitudinal flow window has a number of longitudinal guide plates extending vertically. The rear side edges of the longitudinal guide plates are evenly spaced, and the spacing between the front side edges gradually increases from the middle to the left and right directions. The minimum spacing between the front side edges of the longitudinal guide plates is greater than or equal to the spacing between the rear side edges. A longitudinal diffuser channel is formed between adjacent longitudinal guide plates. The drive window has an air duct penetrating both ends, and a hidden fan is provided in the air duct of the drive window, which can reduce the probability of interference and collision with other components.

[0005] As a preference, the rear side edges of the longitudinal guide plates are in the same vertical plane, and the front side edges of the longitudinal guide plates are also in another vertical plane. The front and rear sides of all longitudinal guide plates are flush.

[0006] As a preference, the longitudinal flow window includes a pair of longitudinal bridging plates. A transverse fixing plate is fixedly connected between the upper and lower ends of the two longitudinal bridging plates respectively. Both ends of all longitudinal guide plates are fixedly connected to the two transverse fixing plates respectively, so as to prevent the inclination angle of the longitudinal guide plates from changing.

[0007] As a preference, the outer side surface of the transverse fixing plate has a mounting plate, and a connection hole is opened on the mounting plate for connecting parts such as bolts to pass through to fix the entire automotive cooling fan assembly in the air conditioner housing assembly.

[0008] As a preference, the rear side edges of the transverse flow guiding plates are in the same vertical plane, and the front side edges of the transverse flow guiding plates are in another vertical plane, and the front and rear sides of the transverse flow guiding plates are flush.

[0009] As a preference, the cross-flow window includes a pair of transverse bridging plates, and a longitudinal fixing plate is fixedly connected between the left end and the right end of each of the two transverse bridging plates, and both ends of all the transverse flow guiding plates are fixedly connected to the two longitudinal fixing plates respectively, ensuring the stability of the inclination angle of the transverse flow guiding plates.

[0010] As a preference, the driving window has two air guiding channels, and a concealed fan is arranged in each of the air guiding channels of the driving window, effectively reducing the diameter of the fan blades of a single fan. Since the power of a single fan is smaller and the resistance received is lower, the working stability is better and the working noise is lower.

[0011] As a preference, a longitudinal beam and a cross beam are fixedly connected in each of the air guiding channels, and the housing of the concealed fan is fixedly connected to the intersection of the longitudinal beam and the cross beam, maintaining the configuration stability of the concealed fan.

[0012] Compared with the prior art, the beneficial effects of the present application are as follows:

[0013] (1) By designing a flow guiding plate structure with a fan-shaped diffusion feature, the direction of the air flow entering the cooling fan assembly is more, and the coverage range of the air flow on the air conditioner radiator is larger. Without using a fan with a larger fan blade diameter, a large-area air radiator can be covered, so the volume of the automotive cooling fan can be made smaller;

[0014] (2) By designing two air guiding channels and arranging concealed fans with smaller fan blade diameters in each air guiding channel, the power required to be output by a single fan and the resistance received are reduced, so that the working stability of the fan is higher, the working noise is lower, and the use process is more quiet.

It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of the present application.

[0024] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects and do not necessarily describe a specific order or sequence.

[0025] The terms "including" and "having" and any variations thereof in the description and claims of the present application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products, or devices.

[0026] Such as Figure 1-6The shown automotive cooling fan assembly includes a longitudinal flow window 2 located in the middle of the entire cooling fan assembly. One open end of the longitudinal flow window 2 is fixedly connected to a cross-flow window 1. Specifically: The cross-flow window 1 has several transverse guide plates 103 extending horizontally. The cross-flow window 1 includes a pair of parallel transverse bridging plates 101. Between the left and right ends of the two transverse bridging plates 101, a longitudinal fixing plate 102 is fixedly connected respectively. The two longitudinal fixing plates 102 are also parallel to each other. The two transverse bridging plates 101 and the two longitudinal fixing plates 102 enclose a rectangle. Both ends of all the transverse guide plates 103 are fixedly connected to the two longitudinal fixing plates 102 respectively. It should be noted that the rear sides of the transverse guide plates 103 are in the same vertical plane, and the front sides of the transverse guide plates 103 are also in another vertical plane. The distances between the rear sides of these transverse guide plates 103 are evenly spaced, but the distances between the front sides gradually increase from the middle to the upper and lower directions. The minimum distance between the front sides of the transverse guide plates 103 is greater than or equal to the distance between the rear sides. A transverse flow expansion channel 104 is formed between adjacent transverse guide plates 103. That is to say, the opening at the front end of the transverse flow expansion channel 104 becomes larger when going up or down from the middle part, forming a sector in the vertical section.

[0027] The structure of the longitudinal flow window 2 is similar to that of the cross-flow window 1, only with different directions. Specifically: The longitudinal flow window 2 has several longitudinal guide plates 203 extending vertically. The longitudinal flow window 2 includes a pair of parallel longitudinal bridging plates 201. Between the upper and lower ends of the two longitudinal bridging plates 201, a transverse fixing plate 202 is fixedly connected respectively. The two transverse fixing plates 202 are also parallel to each other. The two longitudinal bridging plates 201 and the two transverse fixing plates 202 enclose a rectangle. Both ends of all the longitudinal guide plates 203 are fixedly connected to the two transverse fixing plates 202 respectively. The rear sides of the longitudinal guide plates 203 are in the same vertical plane, and the front sides of the longitudinal guide plates 203 are also in another vertical plane. Similarly, the distances between the rear sides of the longitudinal guide plates 203 are evenly spaced, and the distances between the front sides gradually increase from the middle to the left and right directions. The minimum distance between the front sides of the longitudinal guide plates 203 is greater than or equal to the distance between the rear sides. A longitudinal flow expansion channel 204 is formed between adjacent longitudinal guide plates 203. That is to say, the opening at the front end of the longitudinal flow expansion channel 204 becomes larger when going left or right from the middle part, forming a sector in the horizontal section.

[0028] The outer side of the transverse fixing plate 202 has mounting plates 205, which are usually distributed at the four corners of the longitudinal flow window 2. Connection holes 206 are provided on the mounting plates 205 for connecting parts such as bolts to pass through to fix the entire cooling fan assembly on the air-conditioning housing assembly.

[0029] Another open end of the longitudinal flow window 2 is fixedly connected with a driving window 3 for driving air to generate an air flow. The driving window 3 has an air duct 301 penetrating through both ends. A concealed fan 302 is arranged in the air duct 301 of the driving window 3. In this embodiment, the driving window 3 has two air ducts 301, and a concealed fan 302 is arranged in each air duct 301. A longitudinal beam 303 and a cross beam 304 are fixedly connected in each air duct 301. The housing of the concealed fan 302 is fixedly connected to the intersection of the longitudinal beam 303 and the cross beam 304, so as to obtain good restraint stability.

[0030] Working principle: When the concealed fan 302 is started, the fan blades push the air in the air duct 301 out, causing a negative pressure in the air duct 301. The external atmospheric pressure will push the air into the air duct 301 through the cross-flow window 1 and the longitudinal flow window 2. Since the transverse guide plates 103 are arranged along the fan-shaped direction longitudinally, there are more suction angles in the vertical direction; while the longitudinal guide plates 203 are arranged along the fan-shaped direction transversely, so there are more suction angles in the horizontal direction. Therefore, the suction range at the front end of the entire fan assembly is very large, which can more fully cover the air conditioner radiator and improve the heat dissipation balance.

Those skilled in the art should understand that the present application is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present application. Without departing from the spirit and scope of the present application, the present application will have various changes and improvements, and these changes and improvements all fall within the scope of the present application claimed.
