The first feature "below", "below" and "below" the second feature include the first feature being directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0026] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0028] like Figures 1 to 4 As shown, this embodiment provides a cooling device, which includes a wind shield 1, a cooling ring 2 and a radiator assembly. The wind shield 1 has a central opening 11; the cooling ring 2 is arranged on one side of the wind shield 1 and surrounds the central opening 11, and the cooling ring 2 has an air inlet 21, an air outlet 22 and a cooling groove 23. The air inlet 21 and the air outlet 22 are both connected to the cooling groove 23, and the cooling groove 23 abuts against the end surface of one side of the wind shield 1 to form a cooling cavity. The air inlet 21 can be connected to the outlet of the air compressor, and the air outlet 22 can be connected to the inlet of the CPU air handling unit; the radiator assembly is arranged on the other side of the wind shield 1 to cool the compressed gas in the cooling cavity.

[0029] By using the cooling device of the present invention, the cooling ring 2 is arranged on one side of the wind shield 1 and surrounds the central opening 11, and the radiator assembly is arranged on the other side of the wind shield 1. In this way, when the compressed air of the air compressor enters the cooling cavity from the air inlet 21, the radiator assembly can pass through the central opening 11 and reach the cooling ring 2, thereby achieving the purpose of cooling the cooling cavity. Subsequently, the compressed air that has been cooled enters the CPU air handling unit through the air outlet 22, thereby achieving the purpose of cooling the compressed air entering the CPU air handling unit. By using the cooling device of the present invention, the situation of cooling the compressed air through a disc tube structure in the prior art is abandoned. The cooling device of the present invention occupies a small space, is easier to arrange the whole vehicle, improves the aesthetics of the whole vehicle, and does not add components to the assembly of the whole vehicle, simplifies the assembly of the brake pipeline, and improves the braking performance and braking reliability of the whole vehicle.

[0030] It should be noted that since the device is arranged at the front end of the commercial vehicle, which is the windward side, the flowing air and the cooling fan cool the radiator and the intercooler, so that the heat of the compressed air in the wind shield 1 and the cooling ring 2 will also be dissipated, thereby achieving the purpose of cooling the compressed air.

[0031] In this embodiment, the radiator assembly has a cooling fan, which can cool the cooling chamber, wherein the outer diameter of the cooling ring 2 is larger than the outer diameter of the cooling fan. Such a configuration can ensure that the wind from the cooling fan can pass through the central opening 11 to reach the cooling ring 2, thereby achieving the purpose of cooling the cooling ring 2.

[0032] Optionally, the present invention can design cooling fans and cooling rings 2 of different diameters according to the requirements of the overall layout of the vehicle, and can also change the positions of the air inlet 21 and the air outlet 22 according to the position of the air compressor to facilitate the layout of the brake pipeline.

[0033] Specifically, the depth of the cooling groove 23 is 38mm-42mm, and the width of the cooling groove 23 is 10mm-12mm. The depth of the cooling groove 23 is limited within the above-mentioned numerical range, and similarly, the width of the cooling groove 23 is limited within the above-mentioned range, so that sufficient compressed air circulation can be ensured, and the cooling effect can also be ensured. Among them, the depth and width of the cooling groove 23 can be selected according to actual conditions. Specifically, the depth of the cooling groove 23 can be selected as 38mm, 39mm, 40mm, 41mm or 42mm, etc. In this solution, the depth of the cooling groove 23 is 40mm. Similarly, the depth and width of the cooling groove 23 can be selected according to actual conditions. Specifically, the width of the cooling groove 23 can be selected as 10mm, 11mm or 12mm, etc. In this solution, the width of the cooling groove 23 is 11mm.

[0034] Optionally, in this embodiment, the thickness of the cooling ring 2 is less than 30 mm, and the height is less than 50 mm.

[0035] In some embodiments, the cross-sectional shape of the cooling groove 23 can be set to be U-shaped or V-shaped. The above two cross-sectional shapes can increase the flow rate of the compressed air in the cooling cavity, thereby improving the cooling effect.

[0036] Specifically, in an embodiment not shown in the figure, the cooling device also includes a heat sink, which is arranged on the side of the cooling ring 2 away from the wind shield 1. In this way, the heat sink can be used to dissipate heat for the cooling cavity, thereby improving the cooling effect.

[0037] like Figure 1 and Figure 2 As shown, the cooling ring 2 includes a connecting block 24 and an annular cooling body 25 which are connected to each other. The connecting block 24 has an air inlet 21 and an air outlet 22, the annular cooling body 25 has a cooling groove 23, and the annular cooling body 25 is connected to one side of the wind shield 1. The annular cooling body 25 and the wind shield 1 can be connected by welding, casting, gluing and other processes. After the connection is completed, a sealing test should be carried out to ensure that there is no air leakage, and the subsequent installation is carried out according to the wind shield 1 and the cooling ring 2 as an integrated structure.

[0038] Furthermore, the annular cooling body 25 has a blocking plate 251, a first connecting hole 252 and a second connecting hole 253. The air inlet 21 is connected to the cooling groove 23 through the first connecting hole 252, the air outlet 22 is connected to the cooling groove 23 through the second connecting hole 253, and the blocking plate 251 is arranged in the cooling groove 23 and between the first connecting hole 252 and the second connecting hole 253. In this way, the blocking plate 251 can separate the first connecting hole 252 and the second connecting hole 253, so that the compressed air entering from the air inlet 21 through the first connecting hole 252 can flow in a certain direction, thereby improving the cooling effect of the compressed air.

[0039] Specifically, the annular cooling body 25 has a drain port 254, and the cooling device further includes a drain valve, which is installed at the drain port 254, so that the oil and water accumulated in the cooling ring 2 can be drained according to the frequency of use of the vehicle.

[0040] Optionally, the drain valve includes but is not limited to an automatic drain valve, which increases the service life of the CPU air handling unit.

[0041] In this embodiment, the cooling ring 2 is made of aluminum material. In this way, the aluminum material has a low density and good heat dissipation, and can be manufactured by welding, casting and stamping processes.

[0042] The present embodiment also provides a vehicle, comprising an air compressor, a CPU air processing unit and the cooling device in the above scheme, wherein the outlet of the air compressor is connected to the air inlet 21, and the inlet of the CPU air processing unit is connected to the air outlet 22. In the vehicle using the present invention, the cooling ring 2 is arranged on one side of the wind shield 1 and surrounds the central opening 11, and the radiator assembly is arranged on the other side of the wind shield 1. In this way, when the compressed air of the air compressor enters the cooling cavity from the air inlet 21, the radiator assembly can pass through the central opening 11 and reach the cooling ring 2, thereby achieving the purpose of cooling the cooling cavity, and then the compressed air that has been cooled enters the CPU air processing unit through the air outlet 22, thereby achieving the purpose of cooling the compressed air entering the CPU air processing unit. The vehicle using the present invention abandons the situation in the prior art of cooling the compressed air through a disc tube structure. The cooling device of the present invention occupies a small space, the whole vehicle is relatively easy to arrange, and the aesthetics of the whole vehicle is improved. In addition, no components are added to the assembly of the whole vehicle, the assembly of the brake pipeline is simplified, and the braking performance and braking reliability of the whole vehicle are improved.

[0043] The advantages of the present invention are as follows:

[0044] 1. The present invention is composed of a wind shield 1, a cooling ring 2, a radiator assembly, a drain valve and other components. The cooling ring 2 and the wind shield 1 are welded or bonded, and the cooling ring 2 is used to cool the compressed air, which reduces the occupied space of the vehicle and makes the vehicle more beautiful.

[0045] 2. The material of the windshield 1 of the commercial vehicle is basically plastic and thin steel plate through casting and stamping processes. In order to improve the heat dissipation efficiency, the cooling ring 2 is made of aluminum material, which also reduces the weight.

[0046] 3. The cooling ring 2 designed in the present invention does not add any components to the vehicle assembly, simplifies the assembly of the brake line, and improves the braking performance and braking reliability of the vehicle.

[0047] Obviously, the above embodiments of the present invention are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here.
