[0080] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without carrying out creative work are within the scope of protection of this application.

[0081] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0082] In the description of this application, it should be understood that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0083] In the description of this application, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the attached Figure 1 The orientation or position relationship shown is consistent with the orientation or position relationship when the refrigerant circulation equipment and the frame are normally placed, wherein the up-down direction Z is parallel to the direction of gravity, "up" is the same as the direction of gravity, and "down" is opposite to the direction of gravity. The first direction X is perpendicular to the up-down direction, which is the length direction of the frame and the arrangement direction of different condensers in the refrigerant circulation equipment. The second direction Y is perpendicular to the up-down direction Z and the first direction X, which is the width direction of the frame; the orientation words "inside" and "outside" refer to the inside and outside relative to the outline of each component itself.

[0084] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0085] The chiller includes a refrigerant circulation device and a frame. The refrigerant circulation device is arranged on the frame so that the frame supports various components of the refrigerant circulation device (such as a condenser, an evaporator and a compressor, etc.).

[0086] Wind and earthquake resistance are important performance indicators of chillers, which can reflect the chiller's ability to resist earthquakes and tornadoes.

[0087] Earthquakes are highly complex and unique vibrations, characterized by large acceleration loads, complex frequency domain components, and simultaneous multi-directional action. Tornadoes, on the other hand, are powerful wind vortices accompanied by rapidly rotating funnel-shaped cloud columns, generated by intense air convection in extremely unstable weather. The main structural hazards are the wind pressure generated by the shifting air, the negative pressure caused by rapid changes in relative atmospheric pressure, and the impacts caused by tornado projectiles. Therefore, both earthquake and tornado loads require chillers to possess strong wind and earthquake resistance.

[0088] The better the wind and earthquake resistance, the less likely the chiller is to be damaged in earthquakes and tornadoes, the higher the structural reliability, and the longer the service life. Therefore, increasingly higher requirements are currently being placed on the wind and earthquake resistance of chillers.

[0089] However, in the related art, the overall stiffness and strength of the frame are relatively low, making it difficult to meet the increasingly high requirements for wind and earthquake resistance.

[0090] In view of the above situation, the present application provides a frame and a chiller, which improves the wind and earthquake resistance of the chiller by improving the structure of the frame.

[0091] Figures 1-17 The structure of the chiller unit and its frame in this application is shown as an example.

[0092] See also Figures 1-17 In the present application, the chiller 100 includes a frame 10 and a refrigerant circulation device 20. The refrigerant circulation device 20 is arranged on the frame 10, so that the condenser 201, fan 202, evaporator 203, electrical control box 204, compressor 206 and oil separator 207 of the refrigerant circulation device 20 are all supported by the frame 10.

[0093] Among them, see Figures 1-17To improve wind and earthquake resistance, the frame 10 includes a main body 101 and a first reinforcement 3. The main body 101 is used to support the refrigerant circulation device 20 and includes a base 1 and a frame 2. The frame 2 includes a support device 21 and at least one support layer 27. The support device 21 extends upward from the base 1 and includes two sets of outer columns 22 spaced apart along a first direction X. Each set of outer columns 22 includes two outer columns 22 spaced apart along a second direction Y. The at least one support layer 27 is connected to the base 1 via the support device 21 and is used to connect to the condenser 201 of the refrigerant circulation device 20. The first reinforcement 3 is provided on the main body 101 and includes a first crossbeam 31 and two first diagonal beams 32. The first crossbeam 31 extends along the second direction Y. The two first diagonal beams 32 are spaced apart along the second direction Y and inclined in opposite directions. The lower ends of the two first diagonal beams 32 are connected to the first crossbeam 31, and the upper ends of the two first diagonal beams 32 are connected to the frame 2.

[0094] The first reinforcement portion 3 provided can increase the support for the main body 101 in the second direction Y and the up-down direction Z, and in particular, can increase the support for the main body 101 in the second direction Y. Therefore, compared with the case where the first reinforcement portion 3 is not provided in the related art, the stiffness and strength of the frame 10 can be effectively improved, and in particular, the stiffness and strength of the frame 10 in the second direction Y can be effectively improved, so that the frame 10 can better withstand wind loads and seismic loads, and can effectively support the refrigerant circulation equipment 20 even in earthquakes and tornadoes. Therefore, the wind and seismic resistance are better, and the wind and seismic resistance of the chiller 100 can be effectively improved.

[0095] Among them, see Figure 1 and Figure 9 When the two first inclined beams 32 are tilted in opposite directions in the second direction Y, they can either gradually approach each other from bottom to top or gradually move away from each other from bottom to top. Compared to the case where the two first inclined beams 32 gradually approach each other from bottom to top, when the two first inclined beams 32 gradually move away from each other from bottom to top, the two first inclined beams 32 can better provide support in the second direction Y. Therefore, the rigidity and strength of the frame 10 can be more effectively improved, and the wind and earthquake resistance of the chiller 100 can be more effectively improved.

[0096] See also Figure 9In some embodiments, the angle between the first inclined beam 32 and the first crossbeam 31 is c1, 35°≤c1≤65°. In this case, the inclination angle of the first inclined beam 32 is relatively appropriate and can effectively play a supporting role. Therefore, it can better improve the rigidity and strength of the frame 10, and further improve the wind and earthquake resistance of the frame 10 and the chiller 100. For example, in some embodiments, c1=45°. Simulation and other studies have shown that in this case, the first inclined beam 32 can maximize its supporting role. Therefore, it can more effectively improve the rigidity and strength of the frame 10 and enhance the wind and earthquake resistance of the frame 10 and the chiller 100.

[0097] Also, see Figure 9 In some embodiments, the length of the first crossbeam 31 is L, and the length from the end of the first crossbeam 31 to the lower end of the first diagonal beam 32 closest to the corresponding end, on the side away from the corresponding end, is l2, and L / 6≤l2≤L / 2. In this case, the first diagonal beam 32 can effectively play a supporting role, thereby effectively improving the rigidity and strength of the frame 10, and further effectively improving the wind and earthquake resistance of the frame 10 and the chiller 100. For example, in some embodiments, l2=L / 2. Simulation and other studies have shown that in this case, the first diagonal beam 32 can maximize its supporting role, thereby more effectively improving the rigidity and strength of the frame 10, and improving the wind and earthquake resistance of the frame 10 and the chiller 100.

[0098] In the aforementioned embodiments, the first reinforcement portion 3 may be disposed at various positions on the main body 101 .

[0099] For example, in the first direction X, the first reinforcement portion 3 may be located at the end of the body 101 along the first direction X, or, see Figure 1-Figure 7 , located between the two ends of the body 101 along the first direction X. When the first reinforcement portion 3 is located between the two ends of the body 101 along the first direction X, the first reinforcement portion 3 is less likely to interfere with other structural components, making it easier to fully play a supporting role and more convenient to set other reinforcement structures at the ends of the body 101. Therefore, it is more conducive to improving strength and rigidity. For example, see Figure 1-Figure 5 In some embodiments, the two ends of the main body 101 along the first direction X are respectively the first end and the second end, and the first end is used to set the electric control box 204 of the refrigerant circulation device 20. In this case, the first reinforcement part 3 is not located at the end of the main body 101, but is located between the two ends of the main body 101 along the first direction X. The first reinforcement part 3 will not interfere with the electric control box 204 set at the first end, and it is convenient to set the third reinforcement part 6 and the fourth reinforcement part 7 mentioned below at the first end and the second end. Therefore, it is more conducive to improving the strength and rigidity of the frame 10, and further more conducive to improving the wind and earthquake resistance of the frame 10 and the chiller 100.

[0100] For another example, in the up-down direction Z, the first reinforcing portion 3 may be arranged at various positions. Figure 1-Figure 5 The at least one supporting layer 27 of the main body 101 includes a middle layer 28 and a top layer 29 arranged at intervals from bottom to top, respectively connected to the lower and upper parts of the condenser 201, and the first reinforcement portion 3 is located between the middle layer 28 and the top layer 29 in the vertical direction Z. In this case, since the frame 2 includes more than one supporting layer 27, but includes at least two supporting layers 27, the middle layer 28 and the top layer 29 can respectively constrain the lower and upper parts of the condenser 201. Therefore, compared with the case where the frame 2 only includes the middle layer 28, the support firmness of the frame 10 for the condenser 201 can be effectively improved, the stability of the condenser 201 on the frame 10 can be improved, the displacement of the condenser 201 when subjected to earthquakes or wind loads can be reduced, and the overall wind and earthquake resistance of the chiller 100 can be improved. Furthermore, since the first reinforcement 3 is located between the middle layer 28 and the top layer 29 in the vertical direction Z, the height of the first reinforcement 3 more closely matches the height of the condenser 201. Therefore, the first reinforcement 3 can more fully play a supporting role. In particular, together with the frame 2, it can more fully play a supporting role for the condenser 201, thereby more effectively improving the strength and rigidity, and enhancing the wind and earthquake resistance. At the same time, the first reinforcement 3 is located between the middle layer 28 and the top layer 29, so that the first reinforcement 3 is not located on the base 1, but above the base 1. This makes it less likely that the first reinforcement 3 will interfere with components such as the evaporator 203, the compressor 206, and the oil separator 207 located on the base 1, making it more convenient to install the first reinforcement 3, the evaporator 203, the compressor 206, and the oil separator 207.

[0101] In addition, in the above embodiments, the number of the first reinforcement parts 3 is not limited, and can be one, two, or more (ie, three or more, or at least three). Figure 1-Figure 5 When the frame 10 includes at least two first reinforcements 3, the at least two first reinforcements 3 can be arranged at intervals along the first direction X to increase the support function at different positions in the first direction X, thereby more effectively improving the strength and rigidity of the frame 10 and improving the wind and earthquake resistance of the frame 10 and the chiller 100. In particular, see Figure 1 Typically, the first direction X is the length direction of the frame 10, and is also the arrangement direction of different condensers 201 of the refrigerant circulation equipment 20. That is, at least two condensers 201 are usually arranged in the first direction X. Therefore, at least two first reinforcement parts 3 are arranged in the first direction X, which can better enhance the supporting effect of the frame 10 on each condenser 201 of the refrigerant circulation equipment 20 and enhance stability.

[0102] In the first reinforcement portion 3 of the aforementioned embodiments, the upper ends of the two first inclined beams 32 can be connected to the support layer 27 or the support device 21 when connected to the frame 2. When the upper ends of the two first inclined beams 32 are connected to the support device 21, it is easier to obtain appropriate dimensional parameters (such as the inclination angle c1), effectively play a supporting role, and improve strength and rigidity.

[0103] As an example of connecting the upper end of the first inclined beam 32 to the supporting device 21, see Figure 1-Figure 7 In some embodiments, the support device 21 includes not only two groups of outer columns 22, but also an intermediate support 25. The intermediate support 25 is located between the two groups of outer columns 22 along the first direction X and includes two intermediate columns 26. The two intermediate columns 26 of the intermediate support 25 are arranged opposite to each other along the second direction Y, and the upper ends of the two first inclined beams 32 are respectively connected to the two intermediate columns 26 of the intermediate support 25.

[0104] In the above example, since the support device 21 includes two sets of outer columns 22 and an intermediate support 25 having two intermediate columns 26 arranged relative to each other along the second direction Y, the intermediate support 25 can support the portion of the support layer 27 between the two ends along the first direction X. Together with the two sets of outer columns 22, it can achieve a better supporting effect. Therefore, it is also beneficial to improve the strength and rigidity of the frame 10 and enhance its wind and earthquake resistance. Moreover, since the upper ends of the two first inclined beams 32 are respectively connected to the two intermediate columns 26 of the intermediate support 25, not only can the two intermediate columns 26 provide a mounting base for the two first inclined beams 32 and support the first reinforcement 3, but the two first inclined beams 32 can also effectively connect and support the two intermediate columns 26. Therefore, the first reinforcement 3 and the intermediate support 25 can effectively cooperate to better improve the strength and rigidity, and more effectively enhance the wind and earthquake resistance. At the same time, the upper ends of the two first inclined beams 32 are respectively connected to the two middle columns 26 of the middle support 25. This also allows the first reinforcement 3 to be located between the two ends of the body 101 along the first direction X, avoiding interference with other structural components located at the ends, such as the electrical control box 204. This facilitates the full function of the first reinforcement 3, effectively improving strength and rigidity, and enhancing wind and earthquake resistance. Furthermore, when the upper ends of the two first inclined beams 32 are respectively connected to the two middle columns 26 of the middle support 25, the two first inclined beams 32 gradually move away from each other from bottom to top, providing better support, increasing strength and rigidity, and improving wind and earthquake resistance.

[0105] In the case where the supporting device 21 includes an intermediate support 25 having two intermediate columns 26 arranged opposite to each other along the second direction Y, the number of the intermediate supports 25 can be one, two or more. Figure 1-Figure 5When the supporting device 21 includes at least two intermediate supports 25, the at least two intermediate supports 25 can be arranged at intervals along the first direction X to support the supporting layer 27 at different positions in the first direction X, thereby better improving the strength and rigidity of the frame 10.

[0106] Regardless of whether the support device 21 includes one intermediate support 25 or at least two intermediate supports 25, the intermediate column 26 in the support device 21 can adopt an integrated structure or a split structure. When an integrated structure is adopted, the strength and rigidity of the intermediate column 26 are higher, which helps to further improve the strength and rigidity of the frame 10. When a split structure is adopted, it is convenient to disassemble and assemble the detachable connection part of the intermediate column 26 to facilitate the inspection and maintenance of components such as the compressor 206 of the refrigerant circulation device 20 on the frame 10, thereby improving the convenience of disassembly and maintenance.

[0107] In order to take into account the advantages of both the integrated and split intermediate columns 26, see Figures 1-6 In the supporting device 21, a portion of the intermediate columns 26 may adopt a split structure, while another portion of the intermediate columns 26 may adopt an integrated structure. Figures 1-6 In the case where the support device 21 includes at least two intermediate supports 25 spaced apart along the first direction X, at least one intermediate column 26 of the at least two intermediate supports 25 may adopt a split structure, and the intermediate columns 26 of the other part may adopt an integrated structure. In this way, the advantages of the integrated and split intermediate columns 26 can be taken into account, while ensuring high strength and rigidity and facilitating disassembly and maintenance.

[0108] As an example of a split-structure intermediate column 26, see Figures 1-6 In some embodiments, the middle column 26 includes an upper section 261 and a lower section 262, which are arranged in sequence from top to bottom and are detachably connected. Thus, the upper section 261 and the lower section 262 can be removed to inspect and repair components such as the compressor 206 of the refrigerant circulation device 20 on the frame 10, thereby improving the convenience of disassembly and maintenance. The upper section 261 can be welded to at least one support layer 27. Thus, the upper section 261 and the at least one support layer 27 become one, making them more secure, stronger, and more rigid. This helps better support the refrigerant circulation device 20, more effectively reduces the displacement of the condenser 201, and reduces the risk of damage to the pipeline due to the displacement of the condenser 201. The lower section 262 can be detachably connected to the base 1 so that when disassembly and maintenance are required, the lower section 262 can be directly removed, further improving the convenience of disassembly and maintenance.

[0109] In addition, in the case where the supporting device 21 includes the intermediate support 25, in order to further improve the strength and rigidity of the frame 10 and further improve the wind and earthquake resistance, see Figures 1-6 as well as Figure 11-12 In some embodiments, at least one intermediate column 26 is provided with a second diagonal beam 5. The second diagonal beam 5 is inclined, with its lower end connected to the base 1 and its upper end connected to the intermediate column 26. Since the second diagonal beam 5 can provide a reinforcing support, particularly in the second direction Y, it is beneficial to further improve the strength and rigidity of the frame 10, thereby more effectively enhancing its wind and earthquake resistance.

[0110] Among them, see Figure 11 and Figure 12 The angle b between the second inclined beam 5 and the base 1 is 35°≤b≤65°. In this way, the inclination angle of the second inclined beam 5 is more appropriate, which can maximize the supporting effect. Therefore, the strength and rigidity of the frame 10 can be more effectively improved, and the wind and earthquake resistance can be enhanced.

[0111] In addition, other measures may be adopted to increase the rigidity and strength of the frame 10 and enhance the wind and earthquake resistance of the frame 10 and the chiller 100 .

[0112] For example, see Figure 8 In some embodiments, the outer column 22 includes a first column 23 and a second column 24. The first column 23 includes a first plate 231 and two second plates 232. The two second plates 232 are connected to opposite ends of the first plate 231 and are bent relative to the first plate 231. The second column 24 includes a third plate 241 and a fourth plate 242. The fourth plate 242 is connected to one of the second plates 232 via the third plate 241 and is bent relative to the third plate 241. This effectively improves the rigidity and strength of the outer column 22 compared to a case where the outer column 22 includes only the first column 23, preventing the reliability of the overall structure from being affected by insufficient rigidity and strength of the outer column 22. Furthermore, the provision of the second column 24 facilitates the connection (particularly welding) of the outer column 22 to other structural components (such as the fourth diagonal beam 72 described below).

[0113] For example, see Figure 1-Figure 5 In some embodiments, the frame 10 includes a second reinforcement portion 4, which includes two vertical beams 41. The two vertical beams 41 of the second reinforcement portion 4 are spaced apart along the first direction X and extend vertically. The upper ends of the two vertical beams 41 are connected to the condenser 201, and the lower ends of the two vertical beams 41 are connected to the base 1. In this way, the second reinforcement portion 4 can provide vertical support (i.e., in the vertical direction Z) for the refrigerant circulation device 20, thereby improving the vertical rigidity and strength of the frame 10 and the chiller 100, and also improving the wind and earthquake resistance of the frame 10 and the chiller 100.

[0114] The two vertical beams 41 and the condenser 201 can be directly connected or indirectly connected. Figure 1-Figure 5 as well as Figure 10 In some embodiments, the second reinforcement part 4 includes not only two vertical beams 41, but also an upper horizontal plate 42. The two vertical beams 41 of the second reinforcement part 4 are connected to the condenser 201 through the upper horizontal plate 42. At this time, the two vertical beams 41 of the second reinforcement part 4 are indirectly connected to the condenser 201 through the upper horizontal plate 42. Since the upper horizontal plate 42 can be conveniently designed to have a larger area, the connection area with the condenser 201 is increased. Therefore, it is conducive to achieving a more secure connection between the second reinforcement part 4 and the condenser 201, and facilitating the second reinforcement part 4 to more fully play a vertical supporting role, improve vertical stiffness, improve structural reliability, and enhance wind and earthquake resistance. Moreover, the upper horizontal plate 42 can realize the connection between the two vertical beams 41, so that the two vertical beams 41 no longer need to be connected to the condenser 201 separately. Therefore, it is also conducive to reducing assembly difficulty and improving assembly efficiency.

[0115] In addition, the two vertical beams 41 can be directly connected to the base 1 or indirectly connected. Figure 1-Figure 5 as well as Figure 10 In some embodiments, the second reinforcement part 4 includes not only two vertical beams 41, but also a lower transverse plate 43. The two vertical beams 41 of the second reinforcement part 4 are connected to the base 1 through the lower transverse plate 43. At this time, the two vertical beams 41 of the second reinforcement part 4 are indirectly connected to the base 1 through the lower transverse plate 43. Since the lower transverse plate 43 can be conveniently designed to have a larger area, the connection area between the second reinforcement part 4 and the base 1 is increased. Therefore, it is conducive to achieving a more solid connection between the second reinforcement part 4 and the base 1, and facilitating the second reinforcement part 4 to more fully play a vertical supporting role, thereby improving vertical stiffness, improving structural reliability, and enhancing wind and earthquake resistance. Moreover, the lower transverse plate 43 can realize the connection between the two vertical beams 41, so that the two vertical beams 41 no longer need to be connected to the base 1 separately. Therefore, it is also conducive to reducing assembly difficulty and improving assembly efficiency.

[0116] In the aforementioned embodiments, the dimension (ie, height) h3 of the vertical beam 41 in the vertical direction Z can be set according to the distance between the base 1 and the condenser 201. Figure 10 In some embodiments, h3 / 6≤l3≤h3 / 2, where l3 is the distance between the two vertical beams 41 of the second reinforcement 4 in the first direction X. Simulation studies and other research have shown that in this case, the second reinforcement 4 can better perform its vertical support function, thereby more effectively improving the vertical stiffness and strength of the frame 10 and the chiller 100, and enhancing the wind and earthquake resistance of the frame 10 and the chiller 100.

[0117] In addition, in the above embodiments, the number of the second reinforcement portion 4 can be one, two or more (ie at least three). Figure 1-Figure 5 In some embodiments, when the frame 10 includes at least two second reinforcements 4 , the at least two second reinforcements 4 are spaced apart along the first direction X. In this way, the second reinforcements 4 can be used for vertical support at different positions in the first direction X. Since there are more corresponding vertical support points, the vertical stiffness is further improved, thereby more effectively enhancing the wind and earthquake resistance.

[0118] In addition to improving the structure of the outer columns 22 and providing the second reinforcement 4, the aforementioned other measures for improving the rigidity and strength of the frame 10 may also include providing at least one of the third reinforcement 6, the fourth reinforcement 7, the fifth reinforcement 8, the upper beam 91, the lower beam 92, and the rib 95. Each of these will be described below.

[0119] First, the third reinforcement portion 6 will be described.

[0120] See also Figure 1-Figure 7 ,as well as Figure 13 The third reinforcement part 6 is arranged at the first end of the two ends of the main body 101 along the first direction X, and includes a third cross beam 61 and two third inclined beams 62. The third cross beam 61 extends along the second direction Y and is connected to the frame 2. The two third inclined beams 62 are arranged at intervals along the second direction Y and are inclined in opposite directions in the second direction Y. The upper ends of the two third inclined beams 62 are connected to the third cross beam 61, and the lower ends are connected to the base 1.

[0121] The third reinforcement portion 6 provided can provide support at the first end, and in particular, can provide support at the first end in the second direction Y. Therefore, it is beneficial to improve the stiffness and strength of the frame 10, and in particular, it is beneficial to improve the stiffness and strength of the frame 10 in the second direction Y. This is beneficial to improve the wind and earthquake resistance of the frame 10 and the chiller 100.

[0122] Moreover, since the third reinforcement portion 6 extends downward as a whole, it can conveniently avoid the electrical control box 204 and the like arranged at the first end of the refrigerant circulation equipment 20 to avoid interference. In this way, the wind and earthquake resistance of the frame 10 and the chiller 100 can be improved while facilitating the structural arrangement.

[0123] Also, see Figure 14 and Figure 15When the electric control box 204 is provided at the first end, the third reinforcement part 6 can also be connected to the electric control box 204. In this way, the third reinforcement part 6 can also play a role in fixing and supporting the electric control box 204, thereby improving the rigidity and strength of the electric control box 204 and increasing the secure installation of the electric control box 204, which is conducive to further improving the wind and earthquake resistance.

[0124] Among them, see Figure 13 The angle between the two third diagonal beams 62 is k1. In some embodiments, 40° ≤ k1 ≤ 120°. Thus, the inclination angles of the two third diagonal beams 62 are more appropriate, enabling them to fully exert their supporting function, thereby effectively increasing the rigidity of the frame 10 and improving its wind and earthquake resistance. Simulation and other studies have shown that when k1 = 90°, the third reinforcement 6 can best exert its supporting function, thereby further improving the rigidity of the frame 10 and enhancing its wind and earthquake resistance.

[0125] The third reinforcement portion 6 can be connected to the body 101 in a variety of ways. For example, the third reinforcement portion 6 is welded to the body 101. In this case, the third reinforcement portion 6 and the body 101 form an integrated structure, and the rigidity and strength of the frame 10 are higher. Therefore, it is more conducive to improving the rigidity of the frame 10 and enhancing the wind and earthquake resistance.

[0126] Next, the fourth reinforcement portion 7 will be described.

[0127] See also Figure 1-Figure 7 as well as Figure 16 The fourth reinforcement portion 7 is arranged at the second end of the two ends of the main body 101 along the first direction X, and includes a fourth cross beam 71 and two fourth inclined beams 72. The fourth cross beam 71 extends along the second direction Y and is connected to the frame 2. The two fourth inclined beams 72 are arranged at intervals along the second direction Y and are inclined in opposite directions in the second direction Y. The upper ends of the two fourth inclined beams 72 are both located above the fourth cross beam 71 and connected to the frame 2. The lower ends of the two fourth inclined beams 72 are both located below the fourth cross beam 71 and connected to the base 1.

[0128] The fourth reinforcement 7 can provide support at the second end, and in particular, can provide support at the second end in the second direction Y. Therefore, it is beneficial to improve the rigidity and strength of the frame 10, and in particular, it is beneficial to improve the rigidity and strength of the frame 10 in the second direction Y. This is beneficial to improve the wind and earthquake resistance of the frame 10 and the chiller 100. In particular, the two fourth diagonal beams 72 of the fourth reinforcement 7 not only extend downward from the fourth cross beam 71, but also extend upward from the fourth cross beam 71. In this way, the fourth diagonal beams 72 are not only taller, but also have a larger span in the second direction Y, which can better provide support in the second direction Y and the vertical direction Z. Therefore, it is beneficial to improve the rigidity and strength of the frame 10 and enhance the wind and earthquake resistance of the frame 10 and the chiller 100. At the same time, the fourth reinforcement part 7 is arranged at the second end, and the second end is usually not provided with structural components of the refrigerant circulation equipment 20 such as the electric control box 204. Therefore, the fourth inclined beam 72 extending above and below the fourth reinforcement part 7 will not interfere with the structural components of the refrigerant circulation equipment 20 such as the electric control box 204. Therefore, the fourth reinforcement part 7 can be used to increase the rigidity and strength of the frame 10 without affecting the arrangement of structural components of the refrigerant circulation equipment 20 such as the electric control box 204, thereby improving the wind and earthquake resistance of the frame 10 and the chiller 100.

[0129] Among them, see Figure 16 The angle between the two fourth diagonal beams 72 is e1. In some embodiments, 40° ≤ e1 ≤ 120°. Thus, the inclination angles of the two fourth diagonal beams 72 are more appropriate, enabling them to fully exert their supporting function, thereby effectively improving the rigidity of the frame 10 and enhancing its wind and earthquake resistance. Simulation and other studies have shown that when e1 = 60°, the fourth reinforcement 7 can best exert its supporting function, thereby further improving the rigidity of the frame 10 and enhancing its wind and earthquake resistance.

[0130] The fourth reinforcement portion 7 can be connected to the main body 101 in a variety of ways. For example, the fourth reinforcement portion 7 is welded to the main body 101. In this case, the fourth reinforcement portion 7 and the main body 101 form an integrated structure, and the rigidity and strength of the frame 10 are higher. Therefore, it is more conducive to improving the rigidity and strength of the frame 10 and enhancing the wind and earthquake resistance.

[0131] When the fourth reinforcement portion 7 is welded to the main body 101, the upper end of the fourth diagonal beam 72 is welded to the frame 2. When the upper end of the fourth diagonal beam 72 is welded to the frame 2, the upper end of the fourth diagonal beam 72 can be welded to the outer column 22 and / or the top layer 29 of at least one supporting layer 27. In this way, the welding between the upper end of the fourth diagonal beam 72 and the frame 2 can be achieved, thereby improving the rigidity and strength of the frame 10 and enhancing its wind and earthquake resistance. In particular, the welding of the fourth diagonal beam 72 to the top layer 29 also allows the fourth diagonal beam 72 to have a longer length, which is conducive to further enhancing the reinforcing support function of the fourth reinforcement portion 7, more effectively improving the rigidity and strength of the frame 10, and improving its wind and earthquake resistance.

[0132] In order to realize the welding between the fourth inclined beam 72 and the outer column 22, see Figure 16 In some embodiments, the fourth diagonal beam 72 is provided with a first groove 73, and the fourth diagonal beam 72 is welded to the outer column 22 at the first groove 73. This facilitates seamless welding between the fourth diagonal beam 72 and the outer column 22, thereby enhancing the weld strength between the fourth diagonal beam 72 and the outer column 22. This further helps to improve the rigidity and strength of the frame 10, and enhances its wind and earthquake resistance.

[0133] In order to realize the welding between the fourth inclined beam 72 and the top layer 29, see Figure 16 In some embodiments, the fourth diagonal beam 72 is provided with a second groove 74, and the fourth diagonal beam 72 is welded to the top layer 29 at the second groove 74. This facilitates seamless welding between the fourth diagonal beam 72 and the top layer 29, thereby enhancing the weld strength between the fourth diagonal beam 72 and the top layer 29. This further helps to improve the rigidity and strength of the frame 10 and enhance its wind and earthquake resistance.

[0134] Next, the fifth reinforcement portion will be described.

[0135] See also Figures 1-6 as well as Figure 17 The fifth reinforcement portion 8 is provided on at least one outer column 22 and includes two inclined plates 81. The two inclined plates 81 are arranged at intervals along the up-down direction Z and are inclined in opposite directions in the up-down direction Z. Among the two inclined plates 81, the lower end and the upper end of the inclined plate 81 located above are respectively connected to the outer column 22 and the supporting layer 27, and the upper end and the lower end of the inclined plate 81 located below are respectively connected to the outer column 22 and the base 1.

[0136] The fifth reinforcement portion 8 is connected to the outer column 22 to form a K-shape, which can provide support, thereby effectively improving the rigidity and strength of the frame 10, and thus effectively improving the wind and earthquake resistance of the frame 10 and the chiller 100.

[0137] Among them, see Figures 1-6 as well as Figure 17 In some embodiments, the ends of the two diagonal plates 81 of the fifth reinforcement 8 that are not connected to the outer column 22 are farther away from the outer column 22 to which they are connected in the first direction X than the ends connected to the outer column 22. In this case, the two diagonal plates 81 of the fifth reinforcement 8 extend within a plane parallel to the first direction X, and can provide support in the first direction X, thereby increasing the rigidity and strength of the frame 10 in the first direction X. In this way, the fifth reinforcement 8, together with other structures such as the first reinforcement 3 that can provide support in the second direction Y, can increase the rigidity and strength of the frame 10 in different directions, so that the frame 10 has higher rigidity and strength in both the first direction X and the second direction Y, thereby more effectively enhancing structural reliability and improving wind and earthquake resistance.

[0138] See also Figure 17 The angle d between the diagonal plate 81 and the outer column 22 is 35°≤d≤65°. In this case, the inclination angle of the diagonal plate 81 is suitable, enabling it to fully exert its supporting function, thereby effectively improving the rigidity and strength of the frame 10 and enhancing its wind and earthquake resistance. Simulation and other studies have shown that when d=45°, the fifth reinforcement 8 can maximize its supporting function, thereby further improving the rigidity and strength of the frame 10 and enhancing its wind and earthquake resistance.

[0139] Back to Figures 1-6 When at least one supporting layer 27 of the frame 2 includes an intermediate layer 28 and a top layer 29, the upper end of the upper inclined plate 81 of the two inclined plates 81 of the fifth reinforcement 8 can be connected to the intermediate layer 28. In this way, the fifth reinforcement 8 is located relatively lower than the outer column 22, and can effectively support the weaker lower area of the outer column 22. At the same time, the fifth reinforcement 8 can also effectively support the intermediate layer 28 and the parts above it, such as the top layer 29 and the condenser 201 of the refrigerant circulation equipment 20. Therefore, a better support effect can be achieved, thereby more effectively improving the rigidity and strength of the frame 10 and enhancing its wind and earthquake resistance.

[0140] Furthermore, the diagonal plates 81 and the outer columns 22 can be connected in a variety of ways. For example, the diagonal plates 81 and the outer columns 22 can be welded. This allows the fifth reinforcement 8 to form an integral structure with the body 101, further increasing the rigidity and strength of the frame 10 and enhancing its wind and earthquake resistance.

[0141] Next, the upper beam 91 will be described.

[0142] See also Figure 1-Figure 5 as well as Figure 14-15The upper beam 91 is connected to the top of the electrical control box 204 located at the first end of the refrigerant circulation device 20 and extends along the second direction Y to connect to the two outer columns 22 located at the first end. In this way, the upper beam 91 not only connects the electrical control box 204 to the frame 2, but also supports the electrical control box 204 from the top, improving the rigidity and strength of the electrical control box 204, which also helps to improve the wind and earthquake resistance.

[0143] Next, the lower beam 92 will be described.

[0144] See also Figure 1-Figure 5 as well as Figure 14-15 The lower beam 92 is connected to the bottom of the electric control box 204 at the first end of the refrigerant circulation device 20 and is connected to the base 1. In this way, the lower beam 92 not only connects the electric control box 204 to the base 1, but also supports the electric control box 204 from the bottom, improving the rigidity and strength of the electric control box 204, which is also conducive to improving the wind and earthquake resistance.

[0145] Continue to see Figure 1-Figure 5 as well as Figure 14-15 In some embodiments, the frame 10 includes not just one lower beam 92 but at least two lower beams 92 , and the at least two lower beams 92 are spaced apart along the second direction Y. This allows the electrical control box 204 to be supported at multiple points on the bottom, thereby further improving the rigidity and strength of the electrical control box 204 and more effectively enhancing its wind and earthquake resistance.

[0146] Next, the rib plate 95 will be described.

[0147] See also Figures 1-6 The ribs 95 are provided at the junction of the outer columns 22 and the support layer 27. This strengthens the frame 10, increases its rigidity and strength, and improves its wind and earthquake resistance. Furthermore, the ribs 95 protect the welds when the outer columns 22 and the support layer 27 are welded together.

[0148] In the aforementioned embodiments, the base 1 and the frame 2 can be connected in a variety of ways. For example, the base 1 is welded to the outer columns 22. This allows the base 1 and the outer columns 22 to form an integrated structure, increasing the rigidity and strength of the frame 10. This further improves the rigidity and strength of the frame 10, enhancing its wind and earthquake resistance.

[0149] Next, combine Figures 1-17 The illustrated embodiments further illustrate the present application.

[0150] In this embodiment, the refrigerant circulation equipment 20 is a screw unit, and is an air-cooled screw unit dedicated to nuclear power plants. It is more affected by wind loads and seismic loads. Therefore, it is more necessary to equip it with a frame 10 with excellent wind and seismic resistance to better meet the seismic and wind resistance requirements.

[0151] like Figures 1-17 As shown, in this embodiment, the frame 10 includes a body 101, a first reinforcement part 3, a second reinforcement part 4, a second diagonal beam 5, a third reinforcement part 6, a fourth reinforcement part 7, a fifth reinforcement part 8, an upper beam 91, a lower beam 92 and a rib plate 95. The body 101 includes a base 1 and a frame 2.

[0152] The base 1 is used to support the evaporator 203, the compressor 206 and the oil separator 207 of the refrigerant circulation device 20. Figure 1-Figure 4 As shown, in this embodiment, the base 1 is rectangular as a whole, with its length direction along the first direction X and its width direction along the second direction Y.

[0153] The frame 2 is used to support the condenser 201, fan 202 and electric control box 204 of the refrigerant circulation device 20. It is arranged on the base 1 and includes two support layers 27 and a support device 21. The support device 21 includes two sets of outer columns 22 and two intermediate supports 25.

[0154] Among them, two support layers 27 are supported above the base 1 by the support device 21, and are respectively a middle layer 28 and a top layer 29. The middle layer 28 and the top layer 29 are arranged in a spaced manner from bottom to top and are respectively connected to the bottom and top of the condenser 201 to constrain the condenser 201 from the top and bottom ends of the condenser 201, reduce the displacement of the condenser 201 relative to the frame 10, and prevent damage to the pipeline caused by the displacement of the condenser 201.

[0155] In this embodiment, installation spaces are formed between the two intermediate supports 25 and the outer columns 22 and between the two intermediate supports 25 for installing the condensers 201. Thus, in this embodiment, the frame 10 has three installation spaces in total, which can realize the installation of three condensers 201, so that the three condensers 201 can be arranged on the frame 10 at intervals along the first direction X and supported by the frame 10. Figure 1-Figure 4 As can be seen, each condenser 201 is provided with a fan 202 on top. Therefore, three sets of fans 202 can be installed on the frame 10, so that the three sets of fans 202 can be spaced apart along the first direction X and supported by the frame 10. Two adjacent sets of fans 202 are separated by a partition 96. The partition 96 extends along the second direction Y and is connected to the top layer 29.

[0156] Two sets of external columns 22 are disposed at both ends of the base 1 along the first direction X, and each set includes two external columns 22 disposed at both ends of the base 1 along the second direction Y. Thus, the frame 10 includes four external columns 22, and these four external columns 22 are disposed at the four corners of the base 1, supporting the four corners of the middle layer 28 and the top layer 29. In this embodiment, the four external columns 22 are welded to the four corners of the base 1, the middle layer 28, and the top layer 29, forming a single unit with greater rigidity and strength. Ribs 95 are provided at the welds between the middle layer 28 and the four external columns 22 to protect and reinforce the welds, thereby increasing rigidity and strength.

[0157] In this embodiment, an electric control box 204 is provided between the two outer columns 22 at the first end. In this way, the electric control box 204 can be arranged on the frame 2 so that the electric control box 204 can be supported by the frame 2 .

[0158] In this embodiment, the four outer pillars 22 have the same structure. Figure 8 The structure of the outer column 22 is further shown. Figure 8 It can be seen that in this embodiment, each outer column 22 includes a first column 23 and a second column 24, and the first column 23 includes a first plate 231 and two second plates 232. The two second plates 232 are connected to the opposite ends of the first plate 231 and are bent vertically to the same side by the first plate 231, so that the first column 23 is U-shaped. The second column 24 is L-shaped, which includes a third plate 241 and a fourth plate 242. The fourth plate 242 is bent relative to the third plate 241 and welded to one of the second plates 232 through the third plate 241. In this way, the outer column 22 is welded by the U-shaped first column 23 and the L-shaped second column 24, and has high rigidity, which can prevent the structural reliability of the frame 10 and the chiller 100 from being affected by the insufficient rigidity of the outer column 22.

[0159] The two intermediate supports 25 are arranged between the two groups of outer columns 22 and each includes two intermediate columns 26 arranged at both ends of the base 1 along the second direction Y. Thus, the frame 10 includes four intermediate columns 26 located between the two groups of outer columns 22. Figures 1-6As shown, in this embodiment, although the intermediate columns 26 in the two intermediate supports 25 both extend upward from the base 1 to the top layer 29, their structures are different. The two intermediate columns 26 in the intermediate support 25 near the first end are split, comprising a detachably connected upper section 261 and a lower section 262. The upper end of the upper section 261 is welded to the top layer 29, and the lower end is welded to the intermediate layer 28, with a weld plate 97 welded to it. The upper and lower ends of the lower section 262 are connected to the weld plate 97 and the base 1 via fasteners such as bolts. This integrates the upper section 261 with the intermediate layer 28, the top layer 29, the four outer columns 22, and the base 1, providing increased rigidity and strength. Furthermore, the lower section 262 is detachably connected to the upper section 261 and the base 1, facilitating assembly and disassembly for maintenance. The intermediate support 25 near the second end, on the other hand, has both intermediate columns 26 as a single-piece structure, resulting in increased rigidity and strength.

[0160] The first reinforcement portion 3 is mainly used to increase the rigidity in the second direction Y. Figure 1-Figure 5 as well as Figure 9 As shown, in this embodiment, the frame 10 includes two first reinforcements 3, which are spaced apart along the first direction X and correspond one-to-one to the two intermediate supports 25. In this way, the two first reinforcements 3 are located between two adjacent condensers 201. The two first reinforcements 3 have the same structure. Both are arranged between the middle layer 28 and the top layer 29, and each includes a first crossbeam 31 and two first inclined beams 32. The first crossbeam 31 and the two first inclined beams 32 are both roughly U-shaped. The first crossbeam 31 extends along the second direction X, and its two ends are respectively connected to the two intermediate columns 26 of the intermediate support 25. The two first inclined beams 32 gradually move away from each other from bottom to top, wherein the lower ends of the two are spaced apart and connected to the first crossbeam 31 by bolts, while the upper ends of the two are respectively connected to the two intermediate columns 26 of the intermediate support 25 by bolts. In this way, the two first inclined beams 32 are arranged to be tilted in opposite directions in the second direction Y, so that the first reinforcement part 3 is generally in an inverted π shape, which provides effective support in the second direction X and improves the rigidity in the second direction X.

[0161] In this embodiment, the two first inclined beams 32 of the first reinforcement part 3 are symmetrically arranged, and the angles c1 between the two and the first cross beam 31 are equal, both 45 degrees. Figure 9 The length l2 shown is 1 / 2 of the total length L of the first crossbeam 31 , that is, l2=L / 2. At this time, the first reinforcement portion 3 can play a supporting role to the maximum extent.

[0162] The second reinforcement 4 is used to increase the vertical rigidity. Figure 1-Figure 5 as well as Figure 10As shown, in this embodiment, the frame 10 includes three second reinforcement parts 4, which are arranged at intervals along the first direction X and are correspondingly arranged under the three condensers 201. They are connected to the base frame 208 of each condenser 201 to effectively support the three condensers 201. The three second reinforcement parts 4 of this embodiment have the same structure and each includes two vertical beams 41, an upper horizontal plate 42 and a lower horizontal plate 43. The two vertical beams 41 are arranged at intervals along the first direction X, and the upper ends are connected to the base frame 208 of the condenser 201 through the upper horizontal plate 42 (see FIG. Figure 5 ) bolt connection, and the lower end is bolted to the base 1 through the lower cross plate 43. In this way, the second reinforcement part 4 forms a II-type structure, which can provide effective vertical support and improve vertical rigidity.

[0163] In this embodiment, the height of the two vertical beams 41 is h3, and the distance between the two vertical beams 41 is l3, where l3=h3 / 2. At this time, the vertical support of the second reinforcement part 4 exerts the maximum effect.

[0164] The second diagonal beam 5 is arranged on the intermediate column 26, mainly for improving the rigidity in the second direction Y. In this embodiment, each intermediate column 26 is provided with a second diagonal beam 5, so that the frame 10 includes four second diagonal beams 5. Each second diagonal beam 5 has the same structure and is roughly U-shaped. Its lower end is connected to the base 1 by bolts, etc., and its upper end is closer to the intermediate column 26 in the second direction Y relative to the lower end and is connected to the intermediate column 26 by bolts, etc. In this way, the second diagonal beam 5 is arranged obliquely between the intermediate column 26 and the base 1, and the two second diagonal beams 5 arranged on the two intermediate columns 26 of the same intermediate support 25 are inclined in opposite directions in the second direction Y, gradually moving away from each other in the direction from bottom to top.

[0165] The second inclined beam 5 can effectively improve the rigidity in the second direction Y. In this embodiment, the angle b between the second inclined beam 5 and the base 1 is 35°≤b≤65°, so that the second inclined beam 5 can exert the maximum supporting effect.

[0166] The third reinforcement portion 6 is provided at the first end, and is mainly used to increase the rigidity in the second direction Y. Figure 1-Figure 7 as well as Figure 13 As shown, in this embodiment, the third reinforcement portion 6 includes a third crossbeam 61 and two third diagonal beams 62. The third crossbeam 61 extends along the second direction X and is welded to the intermediate layer 28. The two third diagonal beams 62 are spaced apart along the second direction X, extending downward from the third crossbeam 61 and welded to the base 1. The two third diagonal beams 62 gradually approach each other from top to bottom. Thus, the two third diagonal beams 62 are arranged in opposite directions and tilted in the second direction Y between the third crossbeam 61 and the base 1, giving the third reinforcement portion 6 a roughly V-shaped shape.

[0167] The third reinforcement 6 can provide effective support in the second direction Y and improve the rigidity in the second direction Y. The two third diagonal beams 62 are symmetrically arranged on the third crossbeam 61, and the angle k1 between them satisfies 40°≤k1≤120°. When k1 is 90°, the third reinforcement 6 can achieve the best support effect.

[0168] In this embodiment, the third reinforcement part 6 is connected to the electric control box 204 and, together with the upper beam 91 and the lower beam 92, forms a multi-point support for the electric control box 204. Figure 1-Figure 7 as well as Figure 13-15 As shown, in this embodiment, the third crossbeam 61 of the third reinforcement portion 6 is connected to the second connecting member 94 (specifically, an angle steel member) via bolts or the like. The second connecting member 94 is welded to the upper and lower ends of the electrical box 204, thereby connecting the third reinforcement portion 6 to the electrical box 204. Furthermore, a first connecting member 93 is welded to the top of the electrical box 204 and connected to the upper beam 91 via bolts or the like, thereby connecting the upper beam 91 to the top of the electrical box 204. Furthermore, the bottom of the electrical box 204 is connected to multiple lower beams 92 spaced apart along the second direction X via bolts or the like. Each lower beam 92 is connected to the first bottom beam 11 of the base 1, which extends along the second direction Y, via a second bottom beam 12 of the base 1, which extends along the first direction X. As a result, the electrical box 204 is connected to the base 1 via multiple lower beams 92. In this way, the electrical box 204 is fixedly supported in multiple directions and at multiple points by the upper beam 91, the third crossbeam 61 of the third reinforcement portion 6, and the lower beams 92, thereby improving rigidity and strength.

[0169] The fourth reinforcement portion 7 is provided at the second end, and is mainly used to increase the rigidity in the second direction Y. Figure 1-Figure 7 as well as Figure 16 As shown, in this embodiment, the fourth reinforcement portion 7 includes a fourth crossbeam 71 and two fourth inclined beams 72. The fourth crossbeam 71 extends along the second direction Y and is welded to the two outer columns 22 at the second end. The two fourth inclined beams 72 are spaced apart in the second direction Y, and gradually move away from each other from bottom to top in the second direction Y to form a V-shape. The lower ends of the two are welded to the base 1, and the upper ends of the two extend upward to the top layer 29 and are welded to the top layer 29 and the outer columns 22. The upper ends of the two fourth inclined beams 72 are provided with a first groove 73 and a second groove 74, and the fourth inclined beams 72 are seamlessly welded to the second column 24 and the top layer 29 of the outer column 22 through the first groove 73 and the second groove 74 respectively.

[0170] The fourth reinforcement 7 can provide support in the second direction Y, effectively improving the rigidity in the second direction Y. The two fourth diagonal beams 72 are symmetrically arranged on the fourth crossbeam 71, and the angle e1 between each fourth diagonal beam 72 and the base 1 is 60°. In this case, the fourth reinforcement 7 can achieve the best support effect.

[0171] The fifth reinforcement portion 8 is provided on the outer column 22, mainly used to improve the support in the first direction X. Figures 1-6 as well as Figure 17 As shown, in this embodiment, each of the four outer columns 22 is provided with a fifth reinforcement 8, resulting in the frame 10 including four fifth reinforcements 8. Each fifth reinforcement 8 is disposed on the first column 23 of the corresponding outer column 22 and is located relatively low, between the intermediate layer 26 and the base 1. Furthermore, each fifth reinforcement 8 is located on two end surfaces of the body 101 along the second direction Y and comprises two diagonal plates 81. The two diagonal plates 81 of the same fifth reinforcement 8 are spaced apart in the vertical direction Z and extend diagonally upward and downward from the outer column 22, respectively. The upper and lower ends of the upper diagonal plate 81 are welded to the intermediate layer 22 and the outer column 22, respectively, while the upper and lower ends of the lower diagonal plate 81 are welded to the outer column 22 and the base 1, respectively. In this manner, the fifth reinforcement 8 forms a roughly K-shaped connection with the outer column 22, providing reliable support in the first direction X and effectively improving rigidity in the first direction X.

[0172] Among them, the two inclined plates 81 of the same fifth reinforcement part 8 are inclined in opposite directions in the up-down direction Z. When the angle d between the two and the outer column 22 satisfies 35°≤d≤65°, especially when d=45°, the supporting role of the fifth reinforcement part 8 can be maximized.

[0173] Based on the above settings, if Figure 6 As shown, the base 1, four outer columns 22, upper sections 261 of two split intermediate columns 26, two integrated intermediate columns 26, an intermediate layer 28, a top layer 29, a third reinforcement 6, a fourth reinforcement 7, and four fifth reinforcements 8 are welded together to form an integrated support structure, which improves overall rigidity. The integrated support structure has a thickness of 8 mm or greater, achieving both increased rigidity and high strength, meeting earthquake and wind resistance requirements.

[0174] Furthermore, based on the above arrangement, the two first reinforcements 3, the four second diagonal beams 5, the one third reinforcement 6, and the one fourth reinforcement 7 can increase the stiffness in the second direction Y, the three second reinforcements 4 can increase the stiffness in the vertical direction Z, and the four fifth reinforcements 8 can increase the stiffness in the first direction X. This results in the frame 10 having high stiffness in the first direction X, the second direction Y, and the vertical direction Z, effectively improving its earthquake and wind resistance. Specifically, the stiffness in the second direction Y can be effectively improved by means of the first reinforcement 3, the second diagonal beams 5, the third reinforcement 6, and the fourth reinforcement 7, better meeting the frame 10's higher stiffness requirement in the second direction Y and more effectively improving its wind and earthquake resistance.

[0175] Figures 18-20 The vibration simulation results of the frame of this embodiment are shown in FIG. The simulation calculation results show that the main vibration mode frequencies of the frame 10 of this embodiment in the first direction X, the second direction Y and the vertical direction Z can reach 24 Hz respectively (see FIG. Figure 18 ), 29Hz (see Figure 19 ) and 26Hz (see Figure 20 ), while the main vibration mode frequencies of the frame in the vertical direction Z, the first direction X and the second direction Y in the related art are 15 Hz, 12 Hz and 8 Hz respectively. Therefore, the main vibration mode frequencies of the frame 10 in the three directions are significantly improved, and it can more reliably withstand seismic loads and wind loads.

[0176] It can be seen that this embodiment can significantly improve the stiffness and strength of the frame 10 and the chiller 100 in three directions, has higher structural reliability, can better meet the requirements of earthquake resistance and wind resistance, achieve stable operation in an earthquake resistance and wind resistance environment, and can effectively meet the earthquake resistance and wind resistance requirements of special units in nuclear power plants.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
