Detailed implementation manners

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] The embodiments of the present invention provide a diversion structure and an air - conditioning device, which can evenly guide the heat - dissipating medium to the heat exchanger.

[0030] For ease of understanding, the diversion structure of the embodiments of the present invention will be described below. AsFigures 1 to 4 As shown, in an embodiment of the present invention, a flow guiding structure is provided between the blower 170 and the heat exchanger 160. The flow guiding structure includes: a first flow guiding port 110, a second flow guiding port 120, a flow guiding ramp 130, and a plurality of flow guiding members 140. The first flow guiding port 110 is in communication with the blower 170, the second flow guiding port 120 is in communication with the heat exchanger 160, the height of the first end 131 to the second end 132 of the flow guiding ramp 130 gradually increases in the first direction X, the first end 131 is connected to the first flow guiding port 110, and the flow guiding ramp 130 can guide the heat dissipation medium flowing in from the first flow guiding port 110 from the first end 131 to the second end 132.

[0031] The flow guiding members 140 are arranged at intervals along the second direction Y. The heat exchanger 160 is located on one side of the flow guiding structure along the first direction X, the blower 170 is located on one side of the flow guiding structure along the second direction Y. The flow guiding members 140 are arranged between the flow guiding ramp 130 and the heat exchanger 160. The flow guiding members 140 can guide the heat dissipation medium to the second flow guiding port 120. The distance between the flow guiding member 140 close to the first end 131 and the flow guiding ramp 130 is greater than the distance between the flow guiding member 140 close to the second end 132 and the flow guiding ramp 130.

[0032] In an embodiment of the present invention, the blower 170 can drive the external air flow to the first flow guiding port 110, and the flow guiding ramp 130 can guide the air flow at the first flow guiding port 110 to flow from the first end 131 to the second end 132 of the flow guiding ramp 130. During the process of the air flow flowing on the flow guiding ramp 130, since the plurality of flow guiding members 140 are getting closer and closer to the flow guiding ramp 130 in the direction from the first end 131 to the second end 132 of the flow guiding ramp 130, each flow guiding member 140 can guide a part of the passing air flow to the second flow guiding port 120, so that the air flow can flow evenly to the heat exchanger 160.

[0033] The flow guiding structure of the embodiment of the present invention can guide the heat dissipation medium flowing into the first flow guiding port 110 from the first end 131 to the second end 132 of the flow guiding ramp 130. During the process of the heat dissipation medium flowing along the flow guiding ramp 130, the plurality of flow guiding members 140 can successively guide part of the heat dissipation medium to the second flow guiding port 120, so that the heat dissipation medium can flow evenly into the heat exchanger 160, reduce the wind noise and enable the heat exchanger 160 to uniformly heat the heat dissipation medium.

[0034] In an embodiment of the present invention, the flow guiding structure is used for guiding the flow in the air conditioning device 100. It is easy to think that the flow guiding structure of the present invention can also be used for guiding the flow in other devices. The heat dissipation medium of the present invention includes gas and liquid. The fan 170 can drive the gas to flow into the first flow guiding port 110. When the heat dissipation medium is liquid, a driving device such as a water pump can be used to drive the liquid heat dissipation medium to flow into the first flow guiding port 110, so that the liquid heat dissipation medium flows out evenly from the second flow guiding port 120 after passing through the flow guiding structure of the present invention.

[0035] Optionally, the flow guiding member 140 includes a first flow guiding member 141 and at least one second flow guiding member 142. The first flow guiding member 141 is connected to the heat exchanger 160 and is close to the first end 131 of the flow guiding ramp 130. The second flow guiding member 142 is arranged on the side of the first flow guiding member 141 away from the first flow guiding port 110 and is arranged at intervals along the second direction Y. Among them, the number of the second flow guiding members 142 can also be one or two.

[0036] Among all the flow guiding members 140, the first flow guiding member 141 is closest to the first flow guiding port 110, and at the same time, the first flow guiding member 141 has the highest height in the first direction X. The first flow guiding member 141 can intercept a part of the air flow flowing out of the first flow guiding port 110, so that this part of the air flow flows from the second flow guiding port 120 between the first flow guiding member 141 and the first flow guiding port 110 to the heat exchanger 160.

[0037] Optionally, the flow guiding member 140 further includes a third flow guiding member 143, and the third flow guiding member 143 is connected to the second end 132 of the flow guiding ramp 130.

[0038] The third flow guiding member 143 is connected to the second end 132 of the flow guiding ramp 130. Among all the flow guiding members 140, the third flow guiding member 143 is located at the end farthest from the first flow guiding port 110, and the third flow guiding member 143 has the lowest height in the first direction X. The third flow guiding member 143 is used to guide the last remaining air flow to the second flow guiding port 120, so that the remaining air flow can be guided to the heat exchanger 160 to prevent the generation of eddy currents and wind noise.

[0039] In an embodiment of the present invention, the number of the second flow guiding members 142 is two. One of the second flow guiding members 142 is arranged close to the first flow guiding member 141, and the other second flow guiding member 142 is arranged close to the third flow guiding member 143. The second flow guiding member 142 close to the first flow guiding member 141 has a higher height in the first direction X than the second flow guiding member 142 close to the third flow guiding member 143 in the first direction X, so as to ensure that different second flow guiding members 142 can respectively guide a part of the air flow to the heat exchanger 160.

[0040] Optionally, the height of the second deflector 142 near the first deflector 141 in the first direction X is greater than the height of the second deflector 142 near the third deflector 143 in the first direction X. Wherein, the number of the second deflectors 142 is two or more.

[0041] While the first end 131 to the second end 132 of the diversion ramp 130 is gradually inclined upward, the height of the plurality of second deflectors 142 arranged at intervals in sequence in the second direction Y in the first direction X becomes lower and lower, so that the distance between the bottom end of the second deflector 142 and the diversion ramp 130 becomes smaller and smaller. During the process of the airflow flowing from the first end 131 to the second end 132, it is evenly separated by different second deflectors 142 and diverted to the second diversion port 120, and finally flows into the heat exchanger 160.

[0042] Optionally, the ratio of the height difference between every two adjacent deflectors 140 relative to the diversion ramp 130 to the height of the first deflector 141 relative to the diversion ramp 130 is 0.19 to 0.29.

[0043] As Figure 6 、 Figure 7 shown, the ratios of the height differences between two adjacent deflectors 140 relative to the diversion ramp 130 to the height of the first deflector 141 relative to the diversion ramp 130 are respectively (h2 - h1) / h1, (h2 - h3) / h1, h3 / h1.

[0044] By controlling the ratio to be maintained between 0.19 and 0.29, the plurality of deflectors 140 can divide the airflow flowing out of the first diversion port 110 into three or four parts relatively evenly, so as to improve the uniformity of the airflow after the diversion structure diverts the airflow.

[0045] Optionally, the distance between the first diversion port 110 and the first deflector 141 in the second direction Y, and the distance between the deflector 140 farthest from the first diversion port 110 and the adjacent deflector 140 in the second direction Y are less than the distance between any other two adjacent deflectors 140 in the second direction Y. Wherein, the height of the deflector 140 relative to the diversion ramp 130 is the vertical distance between the bottom end of the deflector 140 and the surface of the diversion ramp 130.

[0046] Furthermore, as Figures 5 to 7 shown, in the second direction Y, the distance between the first diversion port 110 and the deflector 140 at the rightmost end of the diversion ramp 130 is the total horizontal distance.

[0047] As Figure 5 、 Figure 6As shown, in the first embodiment of the present invention, the number of the flow guiding members 140 is three. The flow guiding members 140 include one first flow guiding member 141 and two second flow guiding members 142, and the total horizontal distance is d1 + d2 + d3. The ratio of the distance d1 between the first flow guiding port 110 and the first flow guiding member 141 in the second direction Y to the total horizontal distance is 0.2 - 0.3. The ratio of the distance d2 between the first flow guiding member 141 and the adjacent second flow guiding member 142 in the second direction Y to the total horizontal distance is 0.4 - 0.5. The ratio of the distance d3 between the two adjacent second flow guiding members 142 in the second direction Y to the total horizontal distance is 0.2 - 0.3.

[0048] Figure 7 It is a schematic structural diagram of the second embodiment of the present invention. Some structures of the second embodiment are the same as those of the aforementioned first embodiment. The following will describe the differences between the two, and the same parts will not be elaborated.

[0049] As Figure 7 As shown, in the second embodiment of the present invention, the number of the flow guiding members 140 is four. The flow guiding members 140 include one first flow guiding member 141, two second flow guiding members 142 and one third flow guiding member 143, and the total horizontal distance is d1 + d2 + d3 + d4. The ratio of the distance d1 between the first flow guiding port 110 and the first flow guiding member 141 in the second direction Y to the total horizontal distance is 0.2 - 0.3. The ratio of the distance d2 between the first flow guiding member 141 and the adjacent second flow guiding member 142 in the second direction Y to the total horizontal distance is 0.3 - 0.4. The ratio of the distance d_{3} between the two adjacent second flow guiding members 142 in the second direction Y to the total horizontal distance is 0.2 - 0.3. The ratio of the distance d4 between the third flow guiding member 143 and the adjacent second flow guiding member 142 in the second direction Y to the total horizontal distance is 0.1 - 0.2.

[0050] When the fan 170 drives the air flow to flow out from the first flow guiding port 110, the flow velocity of the air flow closer to the wall surface is greater. Therefore, by reducing the distance between the outer flow guiding members 140 in the flow guiding structure and the first flow guiding port 110 or the adjacent flow guiding members 140 in the second direction Y, and increasing the distance between the middle flow guiding members 140 and the adjacent flow guiding members 140 in the second direction Y, the flow velocity of the air flow in different regions is coordinated to ensure the uniformity of the air flow flowing into the heat exchanger 160.

[0051] Furthermore, the flow guiding member 140 includes a first flow guiding portion 1421 and a second flow guiding portion 1422. The second flow guiding portion 1422 is connected to one end of the first flow guiding portion 1421 close to the first flow guiding port 110, and the second flow guiding portion 1422 is bent towards the first flow guiding port 110 relative to the first flow guiding portion 1421.

[0052] In an embodiment of the present invention, the second deflector 142 includes a first deflector portion 1421 and a second deflector portion 1422. It is easy to think that the shapes of the first deflector 141 and the third deflector 143 may be the same as that of the second deflector 142, that is, the first deflector 141 and the third deflector 143 may also include the first deflector portion 1421 and the second deflector portion 1422, or the shapes of the first deflector 141 and the third deflector 143 may be different from that of the second deflector 142, which is not limited in the present invention.

[0053] The second deflector portion 1432 of the second deflector 142 can intercept a part of the air flow, and the first deflector portion 1431 can direct the intercepted air flow towards the heat exchanger 160.

[0054] Furthermore, the length of the first deflector portion 1421 is greater than that of the second deflector portion 1422, and the inclination angle of the second deflector portion 1422 relative to the first direction X is greater than the inclination angle of the first deflector portion 1421 relative to the first direction X.

[0055] In an embodiment of the present invention, the inclination angle of the deflector 140 relative to the first direction X is the inclination angle of the first deflector portion 1431 relative to the first direction X.

[0056] By setting the inclination angle of the second deflector portion 1432 relative to the first direction X to be greater than the inclination angle of the first deflector portion 1431 relative to the first direction X, the interception effect of the second deflector portion 1432 on the air flow can be enhanced, so that the air flow can be directed by the second deflector 142 towards the heat exchanger 160.

[0057] Optionally, the inclination angle of each deflector 140 relative to the deflector ramp 130 is 110° to 130°.

[0058] When the inclination angle of the first deflector portion 1431 of the deflector 140 relative to the deflector ramp 130 is between 110° and 130°, the deflector 140 has the best air flow guiding effect, and the eddy current and wind noise generated by the air flow are the smallest.

[0059] Optionally, the deflector structure further includes a third deflector opening 150, and the third deflector opening 150 is provided on one side of the deflector ramp 130 and communicates with the outside.

[0060] When the air flow generated by the fan 170 is directed by the deflector ramp 130 and the deflector 140 towards the heat exchanger 160, the third deflector opening 150 can serve as a return air opening so that the outside air flows upwards towards the deflector 140 and enters the heat exchanger 160, so as to improve the heating effect of the heat exchanger 160 and the uniformity of the air flow entering the heat exchanger 160.

[0061] Furthermore, the extension length of the diversion ramp 130 along the third direction Z is greater than that of the first diversion port 110 along the third direction Z. The first diversion port 110 faces the diversion ramp 130, and the third diversion port 150 is located on one side of the diversion ramp 130 along the third direction Z. The third direction Z is perpendicular to the first direction X and the second direction Y. Since the extension length of the diversion ramp 130 along the third direction Z is greater than that of the first diversion port 110 along the third direction Z, the diversion ramp 130 can receive all the air flowing out from the first diversion port 110, preventing a part of the air from flowing out from the third diversion port 150.

[0062] As Figure 4 shown, the diversion ramp 130 and the first diversion port 110 are provided on the same side, and the third diversion port 150 is provided on the other side of the diversion ramp 130 to prevent the air flow from the first diversion port 110 from flowing out from the third diversion port 150.

[0063] As shown in Table 1, Table 2, and Figure 7 shown, Table 1 shows the uniformity of the diversion of the heat dissipation medium by the diversion member 140 of the diversion structure in the first embodiment of the present invention at different positions, and Table 2 shows the uniformity of the diversion of the heat dissipation medium by the diversion member 140 of the diversion structure in the second embodiment of the present invention at different positions.

[0064] Among them, h1 is the height of the bottom end of the first diversion member 141 relative to the diversion ramp 130, h2 is the height of the bottom end of one second diversion member 142 relative to the diversion ramp 130, h3 is the height of the bottom end of the other second diversion member 142 relative to the diversion ramp 130, α1 is the inclination angle of the first diversion member 141 relative to the diversion ramp 130, α2 is the inclination angle of one second diversion member 142 relative to the diversion ramp 130, α3 is the inclination angle of the other second diversion member 142 relative to the diversion ramp 130, α4 is the inclination angle of the third diversion member 143 relative to the diversion ramp 130, d1 is the distance between the first diversion member 141 and the first diversion port 110, d2 is the distance between the first diversion member 141 and the adjacent second diversion member 142, d3 is the distance between two adjacent second diversion members 142, d4 is the distance between the third diversion member 143 and the adjacent second diversion member 142, and the units of the above parameters are mm.

[0067]

[0068] Table 2

[0069] In an embodiment of the present invention, the uniformity of the diversion structure for diverting the heat dissipation medium is based on the following formula: z = a×tanα1 + b×tanα2 + c×tanα3 + d×tanα4 + e×d1 + f×d2 + g×d3 + h×d4;

[0070] Wherein, -0.003 ≤ a ≤ -0.002; 0.004 ≤ b ≤ 0.005; 0.006 ≤ c ≤ 0.007; -0.003 ≤ d ≤ -0.002; 0 ≤ e ≤ 0.001; 0.009 ≤ f ≤ 0.01; 0.021 ≤ g ≤ 0.022; 0.004 ≤ h ≤ 0.005, and z is the uniformity of the heat dissipation medium passing through the diversion structure.

[0071] In the first embodiment of the present invention, the deflector 140 includes a first deflector 141 and two second deflectors 142. The airflow flowing out from the first air outlet 110 can be deflected by the first deflector 141 and the second deflectors 142 to the heat exchanger 160, and the remaining airflow finally flows from the second end 132 of the diversion ramp 130 to the heat exchanger 160. Compared with the second embodiment of the present invention, since the first embodiment lacks the third deflector 143 provided at the second end 132 of the diversion ramp 130, it is easy to cause eddy currents and wind noise at the second end 132 of the diversion ramp 130, affecting the heating effect of the heat exchanger 160.

[0072] As shown in Table 1 and Table 2, by comparing the uniformity of the embodiments and comparative examples in the first embodiment and the second embodiment of the present invention, it can be obtained that the uniformity of the heat dissipation medium during diversion in Embodiment 1 of the second embodiment and Comparative Example 2 of the present invention is the best, achieving the best uniform diversion effect on the heat dissipation medium.

[0073] From the above, when the number of deflectors 140 of the diversion structure in the embodiment of the present invention is 4, it is possible to obtain better uniformity while ensuring the product cost, achieving a balance between product performance and cost. When the inclination angle between the deflector 140 and the diversion ramp 130 is within the range of 110° and 130°, the deflector 140 can minimize the eddy currents generated by the heat dissipation medium during diversion of the heat dissipation medium, and direct the evenly divided heat dissipation medium to the heat exchanger 160, with a better diversion effect on the heat dissipation medium.

[0074] As Figures 1 to 6 shown, the embodiment of the present invention further provides an air conditioning device 100, which includes: a heat exchanger 160, the diversion structure of any one of the foregoing embodiments of the present invention, and a blower 170. The heat exchanger 160 can heat the heat dissipation medium, the diversion structure can direct the heat dissipation medium to the heat exchanger 160, and the blower 170 can drive the external heat dissipation medium to flow to the first air outlet 110.

[0075] The diversion structure provided by the embodiment of the present invention is disposed between the fan 170 and the heat exchanger 160. The diversion structure includes: a first diversion port 110, a second diversion port 120, a diversion ramp 130, and a plurality of diversion members 140. The first diversion port 110 is communicated with the fan 170, the second diversion port 120 is communicated with the heat exchanger 160. The height of the first end 131 to the second end 132 of the diversion ramp 130 gradually increases in the first direction X. The first end 131 is connected to the first diversion port 110. The diversion ramp 130 can divert the heat dissipation medium flowing in from the first diversion port 110 from the first end 131 to the second end 132.

[0076] The plurality of diversion members 140 are arranged at intervals along the second direction Y. The heat exchanger 160 is located on one side of the diversion structure along the first direction X, and the fan 170 is located on one side of the diversion structure along the second direction Y. The diversion members 140 are disposed between the diversion ramp 130 and the heat exchanger 160. The diversion members 140 can direct the heat dissipation medium to the second diversion port 120. The distance between the diversion member 140 close to the first end 131 and the diversion ramp 130 is greater than the distance between the diversion member 140 close to the second end 132 and the diversion ramp 130.

[0077] As Figure 8 shown, optionally, the air conditioning device 100 further includes a housing 180. The heat exchanger 160 and the diversion structure are disposed inside the housing 180. The cooperation between the diversion structure and the housing 180 can evenly direct the air flow generated by the fan 170 to the heat exchanger 160. After the air flow is heated by the heat exchanger 160, it evenly flows out of the air conditioning device 100 to achieve the heating function.

[0078] The air conditioning device 100 of the embodiment of the present invention includes a diversion structure. The diversion structure can divert the heat dissipation medium flowing into the first diversion port 110 from the first end 131 of the diversion ramp 130 to the second end 132. During the process of the heat dissipation medium flowing along the diversion ramp 130, the plurality of diversion members 140 can successively divert part of the heat dissipation medium to the second diversion port 120, so as to achieve the purpose that the heat dissipation medium can flow into the heat exchanger 160 evenly, thereby enabling the air conditioning device 100 to reduce the wind noise and output uniform hot air.
