[0046] The features described herein may be implemented in different forms and should not be interpreted as being limited to the examples described herein. Rather, the examples described herein have been provided only to illustrate some of the many possible ways of implementing the methods, devices and / or systems described herein that will be apparent after understanding the disclosure of the present application.

[0047] Throughout the specification, when an element (such as a layer, a segment, or a substrate) is described as being “on”, “connected to”, “bound to”, “over”, or “covering” another element, it may be directly “on”, “connected to”, “bound to”, “over”, or “covering” another element, or one or more other elements may be present between them. In contrast, when an element is described as being “directly on”, “directly connected to”, “directly bound to”, “directly over”, or “directly covering” another element, there may be no other elements present between them.

[0048] As used herein, the term "and / or" includes any one of the associated listed items and any combination of any two or more items.

[0049] Although terms such as "first," "second," and "third" may be used herein to describe various components, assemblies, segments, layers, or portions, these components, assemblies, segments, layers, or portions are not limited by these terms. Rather, these terms are only used to distinguish one component, component, segment, layer, or portion from another component, component, segment, layer, or portion. Therefore, without departing from the teachings of the examples described herein, a first component, component, segment, layer, or portion referred to may also be referred to as a second component, component, segment, layer, or portion.

Therefore, the term "above" includes both "above" and "below" orientations depending on the spatial orientation of the device. The device may also be positioned in other ways (e.g., rotated 90 degrees or in other orientations), and the spatial relational terms used herein will be interpreted accordingly.

In addition, although the examples described herein have various configurations, other configurations are possible as will be apparent after understanding the disclosure of the present application.

[0054] Combine the following Figure 1-Figure 7 A heat dissipation structure 6 provided in the present application is described in detail.

[0055] In this embodiment, a heat dissipation structure 6 is provided; the heat dissipation structure 6 includes a peak section 8, a trough section 9 and a wave surface section 10, wherein a plurality of the peak sections 8, the trough sections 9 and the plane sections are provided, the plurality of peak sections 8 and the plurality of trough sections 9 are arranged alternately, and a wave surface section 10 is provided between adjacent peak sections 8 and trough sections 9, so that the heat dissipation structure 6 is wavy; further, the peak section 8 is a first arc plate 14, the trough section 9 is a second arc plate 15, and the wave surface section 10 is a plane plate 16; adjacent first arc plates 14 and second arc plates 15 are connected by a plane plate 16; a first guide channel 17 is provided between adjacent plane plates 16 connected to the same first arc plate 14; a second guide channel is provided between adjacent plane plates 16 connected to the same second arc plate 15 (the second guide channel is not marked in the figure). In the actual installation process, one end of the heat dissipation structure 6 is close to the fan and the other end is close to the engine; when the car is driving, as the water temperature continues to rise, when the temperature reaches a preset temperature, the control system (the control system is the control system on the car body, not the structure protected by this application, which can be thought of by technicians in this field and will not be elaborated here) controls the fan to start working, and the wind generated by the fan can pass through the first guide channel 17 and the second guide channel.

[0056] Specifically, the heat dissipation structure 6 further includes a window structure 11; the window structure 11 is opened in the wave surface section 10 and includes a first window component 12 close to the fan and a second window component 13 close to the engine.

[0057] Furthermore, the first window assembly 12 has a first window portion which is at a first preset angle with the wavefront segment 10, and the second window assembly 13 has a second window portion which is at a second preset angle with the wavefront segment 10. The first preset angle is greater than the second preset angle, so that an angle difference is formed between the first window assembly 12 and the second window assembly 13. In other words, a structure in which the air inlet angle is greater than the air outlet angle can be formed. In this way, the air intake volume can be increased, the wind resistance can be reduced, and the air intake can pass through the radiator quickly, so that the heat can be rapidly reduced and the heat dissipation efficiency can be improved.

[0058] In summary, the present application improves the window structure 11 so that the first preset angle α of the first window assembly 12 close to the fan is greater than the second preset angle β of the second window assembly 13 close to the engine, that is, the wind inlet angle is greater than the wind outlet angle. In this way, the air intake volume can be increased, the wind resistance can be reduced, and the incoming air can pass through the radiator quickly, so that the heat is rapidly reduced and the heat dissipation efficiency is improved.

[0059] In this embodiment, the first preset angle is 60° and the second preset angle is 30°, that is, when the number of the first window opening and the second window opening is the same, the air intake is twice the air outlet, that is, the air intake is increased, the wind resistance is reduced, and the air intake passes through the radiator quickly, so that the heat drops rapidly and the heat dissipation efficiency is improved.

[0060] In this embodiment, the number of the first window portions is the same as the number of the second window portions. Figure 1 and Figure 2 As shown, four first window portions and four second window portions are provided.

[0061] In this embodiment, the first window portion includes a first inclined plate 19 and a second inclined plate 20 .

[0062] Specifically, the first inclined plate 19 opens to the plane plate 16 at a first preset angle toward the first guide channel 17 and forms a first opening 21 toward the engine; the second inclined plate 20 opens to the plane plate 16 at a first preset angle toward the second guide channel and forms a second opening 22 toward the fan, and the first opening 21 is connected to the second opening 22, so that the first window portion has an air inlet connecting the first guide channel 17 and the second guide channel.

[0063] Furthermore, when the fan is started, the wind first passes through the second guide channel, and then is guided to the first guide channel 17 through the second opening 22 and the first opening 21. Since the first opening 21 and the second opening 22 are both opened on the flat plate 16 at a first preset angle, the air intake volume will be greatly increased.

[0064] In this embodiment, the first window portion further includes a first connecting plate 23 and a second connecting plate 24 .

[0065] Specifically, both ends of the first inclined plate 19 along the length direction thereof are connected to the planar plate 16 through the first connecting plates 23 .

[0066] Specifically, both ends of the second inclined plate 20 along the length direction thereof are connected to the planar plate 16 through the second connecting plates 24 .

[0067] Furthermore, the first connecting plate 23 and the second connecting plate 24 are both triangular plates, and the first inclined plate 19 and the second inclined plate 20 are both rectangular plate structures.

[0068] In this embodiment, the second window portion includes a third inclined plate 25 and a fourth inclined plate 26 .

[0069] Specifically, the third inclined plate 25 opens to the plane plate 16 at a second preset angle toward the second guide channel and forms a third opening 27 toward the engine, and the fourth inclined plate 26 opens to the plane plate 16 at a second preset angle toward the first guide channel 17 and forms a fourth opening 28 toward the fan, and the third opening 27 is connected to the fourth opening 28 so that the second window portion has an air outlet connecting the first guide channel 17 and the second guide channel.

[0070] Furthermore, when the fan is started, the wind first passes through the second guide channel, and then is guided to the first guide channel 17 through the second opening 22 and the first opening 21. Since the first opening 21 and the second opening 22 are both opened on the flat plate 16 at a first preset angle, the air intake volume will be greatly increased.

[0071] After passing through the first window assembly 12 , the wind is directed to the engine through the third opening 27 and the fourth opening 28 .

[0072] In this embodiment, the first window portion further includes a third connecting plate 29 and a fourth connecting plate 30 .

[0073] Specifically, both ends of the third inclined plate 25 along the length direction thereof are connected to the planar plate 16 through third connecting plates 29 .

[0074] Specifically, both ends of the fourth inclined plate 26 along the length direction thereof are connected to the planar plate 16 through fourth connecting plates 30 .

[0075] Furthermore, the third connecting plate 29 and the fourth connecting plate 30 are both triangular plates, and the third inclined plate 25 and the fourth inclined plate 26 are both rectangular plate structures.

[0076] In this embodiment, the heat dissipation structure 6 and the cooling tube 5 can form a radiator core 7. Specifically, a plurality of cooling tubes 5 are provided, and the plurality of cooling tubes 5 are arranged at intervals so that a cooling channel is formed between adjacent cooling tubes 5; the heat dissipation structure 6 is provided in the cooling channel. Furthermore, the cooling tube 5 and the heat dissipation structure 6 are closely attached and welded by brazing.

[0077] During actual use, coolant flows in the cooling channel, and the coolant can exchange heat with the heat generated by the engine to dissipate heat to the engine. When the temperature gradually rises, the fan is turned on to dissipate the generated heat.

[0078] It is worth noting that the fan is a necessary component for heat dissipation in a car. The heat dissipation method of a fan combined with a radiator is a relatively mature technology and can be understood by those skilled in the art. There is no improvement on the fan in this application, so this part of the fan structure will not be described in detail.

[0079] In this embodiment, a radiator is provided. The radiator includes an upper water chamber 1 , a lower water chamber 3 , a first plate 2 , a second plate 4 and the above-mentioned radiator core 7 .

[0080] Specifically, the upper water chamber 1 and the lower water chamber 3 are respectively arranged on two opposite side walls of the radiator core 7 and are connected to the cooling pipe 5; the upper water chamber 1 and the lower water chamber 3 are defined based on Figure 7 In terms of placement.

[0081] Furthermore, the radiator core 7 and the upper water chamber 1 as well as the radiator core 7 and the lower water chamber 3 are connected by press-fitting.

[0082] Specifically, the first plate 2 and the second plate 4 are arranged on the other two opposite side walls of the radiator core 7. That is, the upper water chamber 1, the lower water chamber 3, the first plate 2 and the second plate 4 just surround the radiator core 7.

[0083] Furthermore, the first plate 2 and the radiator core 7, and the second plate 4 and the radiator core 7 are connected by bolts.

[0084] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
