In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0031] In the description of the present invention, it is to be understood that the terms “center”, “longitudinal”, “lateral”, “length”, “width”, “thickness”, “up”, “down”, “front”, “back”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inside”, “outside”, “clockwise”, “counterclockwise”, “axial”, “radial”, “circumferential”, etc., indicating orientations or positional relationships are orientations or positional relationships based on the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0032] 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.

[0033] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0035] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0036] As described in the background technology, the body of the chiller includes at least a compressor, a condenser, an evaporator and a throttle valve, wherein the condenser and the evaporator both use shell and tube, and conventional chillers generally set supporting tube sheets on both sides of the condenser shell and tube water chamber and the evaporator shell and tube water chamber, and the other side of the tube sheet is connected to the building, which can meet the support requirements during normal operation. When an earthquake occurs, the condenser shell and tube water chamber and the evaporator shell and tube water chamber transfer the load to the tube sheet, which is supported by the tube sheet. Since the tube sheet can only support the body of the chiller in one direction, on the one hand, the support strength is obviously insufficient, and on the other hand, since the shock wave is transmitted in all directions, it is easy to cause the vibration amplitudes generated at all angles of the body of the chiller to be different, which may cause the condenser shell and tube water chamber and the evaporator shell and tube water chamber to leak. Therefore, conventional support methods cannot meet the special earthquake resistance requirements of the chiller.

[0037] To solve the above problems, we participated in Figures 1 to 3The present application provides a support structure 100 for a chiller, which is used to support the body 200 of a chiller 300. The support structure 100 for the chiller includes a connection assembly 10, a mounting base 20, a first support plate 30, and a second support plate 40. The connection assembly 10 is used to support the body 200 of the chiller 300. The mounting base 20 and the connection assembly 10 are arranged at intervals along a first direction. The first support plate 30 and the second support plate 40 are both supported and arranged between the connection assembly 10 and the mounting base 20 along the first direction, and the first support plate 30 and the second support plate 40 are connected to each other in a second direction, wherein the first direction and the second direction intersect. In this way, in the support structure 100 for the chiller provided in this embodiment, the connection assembly 10 itself realizes the support of the body 200 of the chiller 300, and the first support plate 30 and the second support plate 40 support the connection assembly 10 along the first direction, thereby realizing the support of the body 200 of the chiller 300 in the first direction. The first support plate 30 and the second support plate 40 are connected to each other in the second direction, so as to realize the support of the body 200 of the chiller 300 in the second direction, thereby realizing the support of the body 200 of the chiller 300 in multiple directions. At the same time, multiple T-shaped pressure-bearing structures are formed between the first support plate 30, the second support plate 40, the connecting assembly 10 and the mounting base 20, which further improves the support rigidity, ensures that the body 200 of the chiller 300 can remain relatively stable even in the epicenter, and improves the seismic resistance of the chiller 300.

[0038] Further, the third direction is defined to intersect with both the first direction and the second direction, the connection assembly 10 and the mounting base 20 both extend longitudinally along the third direction, the first support plate 30 extends straight along the third direction and is supported along the first direction between the connection assembly 10 and the mounting base 20, thereby improving the support stiffness of the body 200 of the chiller 300 in the first direction and the support stiffness in the third direction. The second support plate 40 extends straight along the second direction and is connected to the first support plate 30 extending along the third direction in the second direction, thereby improving the support stiffness of the body 200 of the chiller 300 in the second direction. As a result, the support structure 100 of the chiller provided in the present application ensures the support stiffness of the body 200 of the chiller 300 in three directions, thereby improving the seismic performance of the chiller.

[0039] It can be understood that since the first support plate 30 is intersected and connected with the connecting assembly 10, the first support plate 30 is intersected and connected with the mounting base 20, the second support plate 40 is intersected and connected with the connecting assembly 10, the second support plate 40 is intersected and connected with the mounting base 20, and the first support plate 30 is intersected and connected with the second support plate 40, a plurality of T-shaped pressure-bearing structures are formed between the above-mentioned intersecting structures, which effectively ensures the supporting strength of the supporting structure of the chiller 300.

[0040] In one embodiment, the connection assembly 10 , the mounting base 20 , the first support plate 30 and the second support plate 40 are all made of anti-bending rib plates, and are intersected and connected to form an integral structure, further improving the seismic performance of the chiller 300 .

[0041] Specifically, the thickness of the first support plate 30 and the second support plate 40 is greater than 22 mm, and the width of the mounting base 20 in the second direction is greater than 300 mm, so as to ensure the supporting strength of the first support plate 30 and the second support plate 40, and to still stably support the body 200 of the chiller 300 when the chiller 300 is at the epicenter.

[0042] In one embodiment, the connection assembly 10 has a receiving groove 111 and an opening 112 communicating with the receiving groove 111, and at least a portion of the body 200 of the chiller 300 can be placed in the receiving groove 111 through the opening 112. In this way, a stable connection between the connection assembly 10 and the body 200 of the chiller 300 is achieved, so that the connection assembly 10 can stably support the body 200 of the chiller 300.

[0043] Specifically, the body 200 of the chiller 300 includes at least two shell tubes 210, and the shell tubes 210 can be an evaporator and a condenser, or other structures, which are not limited here. The connection assembly 10 includes at least two connection plates 11, each of which is opened in an arc shape, and each of which has a receiving groove 111 and an opening 112 facing the shell tube 210 and communicating with the receiving groove 111, and each receiving groove 111 contains a shell tube 210. The side of each connection plate 11 facing away from the opening 112 is connected to the second support plate 40 and the first support plate 30. When installing, the shell tube 210 and the connection plate 11 are installed in the corresponding receiving groove 111 in a one-to-one correspondence and fixedly connected by welding or the like, so that the connection assembly 10 can be set according to the shape of the body 200 of the chiller 300, thereby providing effective support.

[0044] Specifically, the radius of each arc-shaped connecting plate 11 should be smaller than the radius of the shell tube 210 housed therein, and should be larger than three-quarters of the radius of the shell tube 210 housed therein, to ensure that the span of the receiving groove 111 of the connecting assembly 10 is sufficient to effectively support the body 200 of the chiller 300.

[0045] In one embodiment, the connection assembly 10 further includes a reinforcing plate 12, which is disposed between two adjacent connecting plates 11, and is used to connect the two adjacent connecting plates 11 along a third direction to improve the supporting stiffness of the supporting structure 100 of the chiller in the third direction.

[0046] In one embodiment, the second support plate 40 includes a plurality of second support plates 40, which are spaced apart along a third direction and each of the plurality of second support plates 40 is interconnected with the first support plate 30 in the second direction, so as to achieve strong support of the connecting assembly 10 by the second support plates 40, thereby improving the supporting stiffness of the body 200 of the chiller 300 through the arrangement of the second support plates 40.

[0047] Specifically, at least two second support plates 40 need to be connected to the side of each connecting plate 11 facing away from the opening 112 to ensure that the second support plates 40 provide strong support to the connecting assembly 10 .

[0048] In one embodiment, the body 200 of the chiller 300 further includes a support tube sheet 220, one end of the support tube sheet 220 in the first direction is connected to the shell tube 210, and the other end in the first direction is connected to the support structure 100 of the chiller. In this way, the load-bearing point of the body 200 is transferred from the support tube sheet 220 to the connection assembly 10, the first support plate 30, the second support plate 40 and the mounting base 20 of the support structure 100 of the chiller through the support tube sheet 220. The support structure 100 of the chiller can not only meet the weight of the body 200, but also make the fixed frequency and stiffness of the shell tube 210 of the chiller 300 at the epicenter similar to those of the building. Under the same earthquake excitation input, the amplitude, response frequency, vibration mode, etc. are not much different, so as to improve the sealing reliability of the body 200 of the chiller 300, such as the evaporator shell tube 210 and the condenser shell tube 210, with low leakage risk and high seismic performance.

[0049] Preferably, support tube sheets 220 can be respectively provided at the two opposite ends in the extension direction of the shell tube 210, and the thickness of the support tube sheets 220 is greater than 8 mm. On the one hand, the load is evenly supported from both ends of the shell tube 210, and on the other hand, the strength of the support tube sheets 220 is ensured to ensure the force balance of the fuselage 300.

[0050] In one of the embodiments, a plurality of mounting holes 60 are further provided on the mounting base 20, and the plurality of mounting holes 60 are opened through the mounting base 20. An anchor bolt is passed through each mounting hole 60, and the anchor bolt is used to connect the supporting structure 100 of the chiller to the building; and, different positions of the mounting holes 60 are set on the mounting base 20 according to the strain response of the chiller 300 to the earthquake response spectrum, so that the load borne by each mounting hole 60 is equal, so as to ensure that the force distribution of the mounting base 20 is uniform.

[0051] Specifically, it is required that under the specified earthquake spectrum input, the load distribution of each mounting hole 60 is uniform (±1000N), and the stress of the anchor bolt should be less than its allowable stress; generally speaking, no less than 4 mounting holes 60 should be set on the supporting structure 100 of each chiller. The diameter of the mounting hole 60 is selected according to the weight of the unit body 200 and the specified response spectrum.

[0052] In one embodiment, the thickness of the first support plate 30, the second support plate 40 and the even-numbered support tube plates 220 are not limited to the above thicknesses, and appropriate materials should be selected according to earthquake intensity and commonly used material specifications.

[0053] Furthermore, the height of the first support plate 30, the second support plate 40 and the support tube plate 220 in the first direction should be arranged as low as possible within the allowable range of the structure of the chiller 300 to reduce the center of gravity of the chiller 300 and improve the seismic performance of the chiller 300.

[0054] According to another aspect of the present application, a chiller 300 is provided, including a body 200 of the chiller 300 and a plurality of support structures 100 of the chiller proposed in the above embodiments, wherein the plurality of support structures 100 of the chiller jointly support the body 200 of the chiller 300, thereby improving the seismic resistance of the chiller 300.

[0055] Specifically, the body 200 of the chiller 300 extends along the second direction, and a plurality of chiller support structures 100 are connected to the body 200 of the chiller 300 at intervals along the second direction, thereby effectively ensuring the seismic strength of the chiller 300 .

[0056] The support structure 100 of the chiller and the chiller provided in the present application have the following advantages:

[0057] (1) The body 200 of the chiller 300 is supported by the connection assembly 10 itself, and the first support plate 30 and the second support plate 40 support the connection assembly 10 along the first direction, thereby supporting the body 200 of the chiller 300 in the first direction. The first support plate 30 and the second support plate 40 are connected to each other in the second direction, thereby supporting the body 200 of the chiller 300 in the second direction, thereby supporting the body 200 of the chiller 300 in multiple directions. At the same time, multiple T-shaped pressure-bearing structures are formed between the first support plate 30, the second support plate 40, the connection assembly 10 and the mounting base 20, which further improves the support stiffness, ensures that the chiller 300 can remain relatively stable even if it is at the epicenter, and improves the seismic performance of the unit;

[0058] (2) By setting a support tube sheet 220, one end of the support tube sheet 220 in the first direction is connected to the shell tube 210, and the other end in the first direction is connected to the support structure 100 of the chiller. In this way, the load-bearing point of the fuselage 200 is transferred from the support tube sheet 220 to the connection assembly 10, the first support plate 30, the second support plate 40 and the mounting base 20 of the support structure 100 of the chiller through the support tube sheet 220. The support structure 100 of the chiller can not only meet the weight of the fuselage 200, but also make the fixed frequency and stiffness of the shell tube 210 of the chiller 300 at the epicenter similar to those of the building. Under the same earthquake excitation input, the amplitude, response frequency, vibration mode, etc. are not much different, thereby improving the sealing reliability of the fuselage 200 of the chiller 300, such as the evaporator shell tube 210 and the condenser shell tube 210, with low leakage risk and high seismic performance.

[0059] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
