[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention.

[0038] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0039] The traditional "G"-shaped condenser assembly and the "C"-shaped condenser assembly both have low heat exchange efficiency in the wind field, especially at the bottom of the condenser assembly, where the heat exchange efficiency is not ideal. Based on this, the present application proposes a condenser assembly 20 and a heat exchange device 10, which can improve the heat exchange efficiency.

[0040] Please refer to Figure 1 and Figure 2 In one embodiment, the heat exchange device 10 includes a condenser assembly 20, and the condenser assembly 20 includes a first condenser 100 and a second condenser 200. The first condenser 100 and the second condenser 200 both include conventional components for realizing heat exchange functions in the prior art, such as fins, copper tubes, and elbows. A first air inlet 120 is formed in the circumferential portion of the first condenser 100, and a second air inlet 220 is formed in the circumferential portion of the second condenser 200. When the external wind passes through the first air inlet 120, heat exchange is realized at the first air inlet 120. Similarly, when the external wind passes through the second air inlet 220, heat exchange is realized at the second air inlet 220.

[0041] Please refer to Figure 2 and Figure 3 The first condenser 100 is arranged to form a first air duct 110, and the first air inlet 120 is connected to the first air duct 110; the second condenser 200 is arranged outside the first air duct 110, and the second condenser 200 is connected to the first condenser 100 and is arranged to form a second air duct 210 with the first air inlet 120, and the circumferential part of the second condenser 200 is formed with a second air inlet 220 connected to the second air duct 210. Please refer back to Figure 1The condenser assembly 20 further includes a first fan 500 and a second fan 600. The first fan 500 is disposed in the second air duct 210. The second fan 600 is used to drive the wind to enter the first air duct 110 along the first air inlet 120 and be discharged along the air outlet of the first air duct 110. For details, please refer to Figure 1 The air outlet directions of the first fan 500 and the second fan 600 may be perpendicular to each other, thus reducing the space occupied by the second fan 600 in the first air duct 110, and thus there is a larger space in the first air duct 110 for arranging other pipeline systems.

[0042] When the above-mentioned condenser assembly 20 and heat exchange equipment 10 are in use, the first fan 500 can be arranged in the second air duct 210. Under the action of the first fan 500, the external wind can first pass through the second air inlet 220, enter the second air duct 210 after the first heat exchange at the second air inlet 220, and then the wind in the second air duct 210 enters the first air duct 110 through the first air inlet 120, and undergoes a second heat exchange through the first air inlet 120. In this way, the external wind can undergo two heat exchanges, thereby improving the heat exchange efficiency. Furthermore, compared to the traditional single "G"-shaped condenser assembly and the "C"-shaped condenser assembly, the present application can fully utilize the spatial layout to divide the condenser assembly 20 into a first condenser 100 and a second condenser 200 without changing the overall size, and the first condenser 100 and the second condenser 200 are surrounded to form a second air duct 210. At this time, part of the wind can enter the first air duct 110 after two heat exchanges, and then be discharged through the first air duct 110, thereby improving the heat exchange efficiency.

[0043] Please refer to Figure 1 and Figure 2 In order to improve the heat exchange efficiency of the condenser assembly 20, in some embodiments, the number of the first fans 500 is at least two, and all the first fans 500 are arranged at intervals along the depth direction of the second air duct 210. The depth direction of the second air duct 210 is shown as F.

[0044] Please refer to Figure 2 The second fan 600 can be arranged at the air outlet of the first air duct 110 . Under the action of the second fan 600 , the wind enters the first air duct 110 along the first air inlet 120 and is discharged along the air outlet of the first air duct 110 .

[0045] Please refer to Figures 2 to 4In some embodiments, the first air inlet 120 is formed with a first bending section (not shown), the second condenser 200 includes a second bending section (not shown), the bending trends of the first bending section and the second bending section are consistent, and at least a portion of the first bending section extends into the bending inner angle of the second bending section and is connected to the second bending section. In this way, the first condenser 100 and the second condenser 200 can be made more compact. The first bending section and the second bending section are surrounded to form a second air duct 210, and the second bending section is formed with a second air inlet 220 connected to the second air duct 210.

[0046] The shapes of the first bending section and the second bending section can be various, for example, please refer to Figures 2 to 4 In some embodiments, the first bending section includes a first section 132, a second section 134 and a third section 136, the third section 136 is arranged opposite to the first section 132, the first section 132 is connected to the third section 136 through the second section 134, and the third section 136 and the first section 132 are located on the same side of the second section 134; at this time, it can be understood that the second section 134 is arranged at an angle to the first section 132 and the third section 136, and the angle between the second section 134 and the first section 132 and the angle between the second section 134 and the third section 136 can be 90° or about 90°.

[0047] Please refer to Figures 2 to 4 The second bending section includes a fourth section 222, a fifth section 224 and a sixth section 226, the fourth section 222, the fifth section 224 and the sixth section 226 are all provided with a second air inlet 220, the fourth section 222 and the sixth section 226 are arranged opposite to each other, the fourth section 222 is connected to the sixth section 226 through the fifth section 224, and the fourth section 222 and the sixth section 226 are located on the same side of the fifth section 224; at this time, it can be understood that the fifth section 224 is arranged at an angle with the fourth section 222 and the sixth section 226, and the angle between the fifth section 224 and the fourth section 222, and the angle between the sixth section 226 and the fifth section 224 can be 90° or about 90°.

[0048] Please refer to Figures 2 to 4 , the second section 134 and the third section 136 extend into the inner angle of the second bending section, the third section 136 is connected to the sixth section 226, and the orthographic projection of the third section 136 toward the sixth section 226 at least partially falls on the sixth section 226. At this time, it can be understood that there is an overlap between the third section 136 and the sixth section 226. The end of the fourth section 222 away from the fifth section 224 is spaced from the second section 134, and the first section 132, the second section 134, the third section 136, the fourth section 222, the fifth section 224 and the sixth section 226 are arranged to form the second air duct 210.

[0049] For details, please refer to Figure 4, in some embodiments, one end of the third section 136 away from the second section 134 is connected to one end of the sixth section 226 away from the fifth section 224 through the side plate 300. In this way, the first condenser 100 and the second condenser 200 can be integrated into an integral structure.

[0050] Please refer to Figure 2 , specifically in one embodiment, the condenser assembly 20 further includes a shielding plate 400. One end of the shielding plate 400 is connected to the fourth section 222, and the other end of the shielding plate 400 extends in a direction close to the second section 134 to shield the gap formed by the spaced arrangement between the fourth section 222 and the second section 134.

[0051] Please refer to Figure 3 , in one embodiment, the distance between the outer surface of the first section 132 located outside the first air duct 110 and the outer surface of the third section 136 located outside the first air duct 110 is D, the distance from the outer surface of the fourth section 222 located outside the second air duct 210 to the outer surface of the sixth section 226 located outside the second air duct 210 is A, and the thickness of the sixth section 226 is H. Wherein, A = D + H. In this way, within this range, the first condenser 100 and the second condenser 200 can be made more compact in the height direction. Further, H satisfies 35mm < H < 60mm. When the thickness H of the sixth section 226 is within this range, the heat exchange efficiency of the second condenser 200 can be improved preferably; wherein, H can be: 35mm, 40mm, 45mm, 50mm, 55mm or 60mm.

[0052] Please refer to Figure 3 , in one embodiment, the first air inlet part 120 further includes a seventh section 138. The seventh section 138 is disposed opposite to the second section 134. The seventh section 138 is connected to the second section 134 through the first section 132. The seventh section 138, the first section 132, the second section 134 and the third section 136 enclose to form the first air duct 110; the distance from the end of the sixth section 226 away from the fifth section 224 to the outer surface of the fifth section 224 located outside the second air duct 210 is B, and the distance between the outer surface of the seventh section 138 located outside the first air duct 110 and the outer surface of the fifth section 224 located outside the second air duct 210 is C. The height of the condenser assembly 20 is L. Wherein, 2(D - H) ≤ L ≤ C; the height L of the condenser assembly 20 has a great influence on the air volume and heat exchange effect of the second condenser 200. When the height L of the condenser assembly 20 satisfies this relationship, the overall machine space layout and heat exchange are better.

[0053] Further, it is also necessary to satisfy 0.3 ≤ B / C ≤ 0.5 between B and C. Since two heat exchange cavities are formed after the first condenser 100 and the second condenser 200 are spliced, the first condenser 100 can be the main heat exchange cavity, and the second condenser 200 can be formed as the auxiliary heat exchange cavity. When the volume of the main heat exchange cavity needs to be larger than that of the auxiliary heat exchange cavity, the heat exchange between the first condenser 100 and the second condenser 200 can be ensured to be uniform.

[0054] Further, please refer to Figure 3 , the distance from the surface of the seventh section 138 located in the first air duct 110 to the surface of the second section 134 located in the first air duct 110 is E, and the distance from the surface of the fifth section 224 located in the second air duct 210 to the surface of the second section 134 located outside the first air duct 110 is G, where 0.2 < G / E < 0.4. When within this range is satisfied, the heat exchange between the first condenser 100 and the second condenser 200 can be ensured to be uniform.

For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly defined.
