In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below. Of course, they are merely examples, and the purpose is not to limit the utility model. In addition, the utility model may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art may be aware of the application of other processes and / or the use of other materials.

[0060] The chiller in this application is mainly used in commercial air conditioners, which perform the refrigeration cycle of the air conditioner by using the compressor, condenser, expansion valve and evaporator in the chiller. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation to cool or heat the indoor space.

[0061] The low-temperature and low-pressure refrigerant enters the compressor, which compresses it into high-temperature and high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0062] The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the low-temperature and low-pressure refrigerant gas to the compressor. The evaporator can achieve a cooling effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the entire cycle, the air conditioner can adjust the temperature of the indoor space.

[0063] The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.

[0064] The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an evaporator. When the indoor heat exchanger functions as a condenser, the air conditioner functions as a heater in a heating mode, and when the indoor heat exchanger functions as an evaporator, the air conditioner functions as a cooler in a cooling mode.

[0065] According to the different working principles of the compressor, water-cooled chillers are divided into screw chillers, scroll chillers and centrifugal chillers.

[0066] The compressor of a screw chiller is generally large in size, and the compressor part is often the widest part of the unit. In order to avoid this during lifting and transportation, some manufacturers isolate the protruding parts from the car fence with insulation cotton or other soft materials before lifting and transportation.

[0067] It is impossible to avoid accidents through workers' lifting operations. The filling material isolation method during operation is prone to the falling off of the filling material due to the ups and downs of the driving section and the driver's driving state. Soft materials such as thermal insulation cotton can only play a buffering role and cannot completely avoid damage to the compressor's external oil return pipe and valve components. Based on the above background, this application proposes a chiller with a protective part.

[0068] Below, the structure of the chiller is described in detail:

[0069] refer to Figure 1 The present application proposes a chiller, including a compressor 100, an expansion valve, a heat exchanger group 200 and a protective member 400. The heat exchanger group 200 includes a condenser 220 and an evaporator 210. The compressor 100 is used to compress a low-temperature and low-pressure refrigerant fluid into a high-temperature and high-pressure refrigerant fluid. An input end and an output end are formed on the compressor 100. The input end is connected to the evaporator 210, and the output end is connected to the condenser 220.

[0070] Due to the functional characteristics of the compressor 100 itself, a valve assembly 102 and a pipe assembly 101 are provided outside the compressor 100, and the protective member 400 is covered on the outside of the valve assembly 102 and / or the pipe assembly 101 to play a protective role.

[0071] The chiller involved in this application mainly relates to a screw-type water-cooling unit, in which a condenser 220 and an evaporator 210 are arranged side by side, and a compressor 100 is fixed above the evaporator 210 .

[0072] refer to Figure 2 The condenser 220 and the evaporator 210 are both cylindrical in shape. In order to facilitate the connection and fixation of the compressor 100 and the evaporator 210 , a connecting seat 110 is further provided on the side wall of the compressor 100 .

[0073] The connection base 110 is formed on the side wall of the compressor 100 by welding, and a connection leg is formed on the connection base 110 for being connected and fixed to the evaporator 210 .

[0074] A support assembly is preset on the evaporator 210, and the positions of the connecting seat 110 and the support assembly correspond to each other. The connecting seat 110 is fixed on the support assembly through connecting legs.

[0075] In order to improve the supporting strength of the supporting seat 300 and disperse the pressure exerted by the compressor 100 on the evaporator 210 , the supporting assembly includes at least two supporting seats 300 spaced apart along the axial direction of the evaporator 210 .

[0076] When the support assembly includes two support seats 300 , the two support seats 300 correspond to two ends of the compressor 100 to ensure support stability.

[0077] When the number of the support assemblies is greater than two, except for the two support seats 300 disposed at both ends of the compressor 100 , the remaining support seats 300 are disposed at intervals in the middle of the compressor 100 .

[0078] In addition, reference Figure 4 In order to improve the connection strength between each support seat 300 and the evaporator 210 and avoid the contact area between the support seat 300 and the evaporator 210 being too small, which may cause damage between the support seat 300 and the evaporator 210 under the action of gravity of the compressor 100, the support seat 300 is designed to be connected to the evaporator 210 in a direction perpendicular to the axis of the evaporator 210.

[0079] The connection seats 110 of the compressor 100 are symmetrically arranged on both sides with the central axis of the compressor 100 as the symmetry axis, and at least two groups of connection seats 110 are arranged along the axial direction of the compressor 100 .

[0080] The two symmetrically arranged connecting seats 110 are connected to the same supporting seat 300 , and the length of the supporting seat 300 is greater than the length between the two connecting seats 110 . Then, the supporting seat 300 can disperse the gravity of the compressor 100 onto the outer wall of the evaporator 210 .

[0081] A conforming surface 311 adapted to the outer wall of the evaporator 210 is formed at the bottom of the support base 300 , and the support base 300 is welded to the outer wall of the evaporator 210 via the conforming surface 311 .

[0082] Under the action of the conformal surface 311 , the support base 300 disperses the gravity of the compressor 100 on the side wall of the evaporator 210 , which is beneficial to improving the support strength.

[0083] The support seat 300 includes two support vertical portions 310 spaced apart and a support horizontal portion 320 located between the two support vertical portions 310 . The connection seat 110 is detachably connected to the support horizontal portion 320 via a fastener 130 .

[0084] The fastener 130 is specifically a fastening bolt. A washer and a spring washer are further provided between the fastener 130 and the connecting seat 110 to increase the stability of the connection.

[0085] The two supporting vertical parts 310 and the supporting horizontal part 320 can be integrally formed by sheet metal.

[0086] Alternatively, the supporting vertical portion 310 and the supporting horizontal portion 320 may also be processed separately and then fixedly connected by welding or mechanical connection.

[0087] The conformal surface 311 is formed at the bottom of the supporting stand 310 and is directly connected to the outer wall of the evaporator 210 .

[0088] The supporting cross portion 320 is a flat plate structure with a supporting plane formed thereon. The connecting legs at the bottom of the connecting seat 110 are directly fixed on the supporting cross portion 320 , so that the connection and fixation with the evaporator 210 can be achieved.

[0089] In order to avoid errors during the manufacturing and assembly process, the connection hole at the bottom of the connection seat 110 is designed as a long hole to improve the degree of adaptation between the connection seat 110 and the mounting seat.

[0090] refer to Figure 2 , Figure 3 The connecting seat 110 and the mounting seat are fixedly connected by a fastener 130. The fastener 130 is specifically a fastening bolt. The fastening bolt passes through the connecting holes on the connecting seat 110 and the supporting seat 300 to fix them.

[0091] In some embodiments of the present application, the compressor 100 may generate vibrations during operation. In order to reduce vibration transmission, a vibration reduction portion 120 is provided between the connecting seat 110 and the supporting seat 300 .

[0092] The material of the vibration-absorbing part 120 is rubber, and a through hole is formed thereon for the fastener 130 to pass through.

[0093] The valve assembly 102 and the pipe assembly 101 formed outside the compressor 100 protrude outside the compressor 100. Compared with the relatively strong structures such as the compressor 100 shell and the evaporator 210 shell, the structures of the valve assembly 102 and the pipe assembly 101 themselves are relatively fragile. Therefore, the protective member 400 is mainly covered on the outside of the valve assembly 102 and the pipe assembly 101.

[0094] The connection seat 110 and the support seat 300 are located beside the valve assembly 102 and the pipe assembly 101 , and the protection member 400 is fixed on the connection seat 110 or the support seat 300 .

[0095] Combination Figure 5 The protective member 400 specifically includes a lap portion 410 detachably connected to the connecting seat 110 or the supporting seat 300 and a protective portion 420 arranged at an angle to the lap portion 410 . The protective portion 420 is configured to cover the outside of the pipe assembly 101 and / or the valve assembly 102 .

[0096] The overlapping portion 410 and the protecting portion 420 are an integrally formed structure, or the overlapping portion 410 and the protecting portion 420 are separately processed and formed and then connected into one by welding or other mechanical connection methods.

[0097] The overlapping portion 410 is formed with overlapping holes 411 for fixing on the supporting cross portion 320. Similarly, in order to avoid processing and assembly errors, the overlapping holes 411 are configured as elongated holes.

[0098] In order to improve the connection strength between the protective part 420 and the overlapping part 410 and prevent the protective part 420 from being deformed after a collision and causing a collision with the valve assembly 102 and the pipe assembly 101, a reinforcing part 430 is provided between the protective part 420 and the overlapping part 410. The reinforcing part 430 is specifically a reinforcing diagonal brace provided between the overlapping part 410 and the protective part 420, which is beneficial to improving the structural strength of the protective part 420 and preventing it from being deformed.

[0099] The reinforcing portion 430 is fixed to the protective portion 420 and the overlapping portion 410 by welding. The overlapping portion 410 is fixed on the connecting seat 110 or the supporting seat 300. The protective portion 420 is supported on the outside of the pipe assembly 101 and / or the valve assembly 102, and a gap is formed between the protective portion 420 and the pipe assembly 101 and / or the valve assembly 102.

[0100] In addition, in some other embodiments, according to actual protection requirements, a protective upper edge (not shown) may also be provided on the top of the protective portion 420. The protective upper edge is formed on the top of the protective portion 420 and is bent toward the pipe assembly 101 and / or the valve assembly 102 to form protection above the pipe assembly 101 and / or the valve assembly 102.

[0101] The specific structure of the protective member 400 and the fixing position on the evaporator 210 or the compressor 100 are described in detail below:

[0102] refer to Figure 1-Figure 3 In some embodiments of the present application, the overlapping portion 410 is fixed to the lower surface of the supporting cross portion 320 and is directly connected to the lower surface of the supporting cross portion 320 , and the fastener 130 fixes the connecting seat 110 , the supporting cross portion 320 and the overlapping portion 410 .

[0103] This type of fixing method of the overlap portion 410 does not require additional openings and can be achieved through the original fastening positions of the connecting seat 110 and the supporting seat 300, and will not affect the fixing position of the compressor 100.

[0104] refer to Figure 6 , Figure 7In other embodiments of the present application, the overlap portion 410 is fixed to the upper surface of the supporting cross portion 320, the upper side of the overlap portion 410 contacts the vibration-damping portion 120, the overlap portion 410 is connected between the vibration-damping portion 120 and the supporting seat 300, and the fastener 130 fixes the connecting seat 110, the overlap portion 410 and the supporting cross portion 320.

[0105] Compared with the previous embodiment, in this connection mode, since the overlapping portion 410 itself has a certain thickness, the installation height of the connecting seat 110 corresponding to this position will be slightly higher than the installation height of other mounting seats.

[0106] The compressor 100 may produce a small range of deflection. In order to avoid this situation, a pad can be installed between other mounting seats and the connecting seat 110 to compensate for the installation height of the overlapping portion 410 to ensure the stability of the compressor 100.

[0107] refer to Figure 8-Figure 12 In other embodiments, the overlapping portion 410 is fixed above the connecting seat 110, and the fastener 130 fixes the overlapping portion 410, the connecting seat and the supporting cross portion 320.

[0108] The overlapping portion 410 in this embodiment is fixed on the compressor 100 , and compared with the previous embodiment, it will not affect the installation height of the compressor 100 .

[0109] Taking into account the specific positions of the valve assembly 102 and the pipe assembly 101 of the compressor 100, the protective part 420 is ensured to provide comprehensive protection for the valve assembly 102 and the pipe assembly 101. When the overlapping part 410 is fixed on the connecting seat 110, the height can be adjusted through the bending part 413 to achieve the adjustment of the relative position between the protective part 420 and the overlapping part 410.

[0110] In addition, reference Figure 5 In some embodiments, in order to reduce the weight of the protective member 400 as much as possible and avoid excessive gravity of the water cooling unit, a weight reduction opening 421 is opened on the protective portion 420.

[0111] The number and size of the weight-reducing openings 421 are designed and adjusted according to actual needs.

[0112] In some embodiments of the present application, the valve assembly 102 and the pipe assembly 101 are arranged on the outside of the oil tank of the compressor 100, and the pipe assembly 101 includes an oil return pipe connected to the oil tank. A cover plate 103 is detachably connected to the outside of the oil tank through fastening screws 104, and an intermediate recess is formed on each fastening screw 104.

[0113] Since the protective member 400 is mainly fixed by the lap joint, the upper part of the protective part 420 may shake during the hoisting and transportation process, and there is also a risk of colliding with the valve assembly 102 and the pipe assembly 101.

[0114] In order to prevent the protection portion 420 from shaking and increase its stability, at least one positioning portion 440 is formed on the protection portion 420 .

[0115] The positioning portion 440 is a positioning column structure formed on one side of the protection portion 420 and extending toward the compressor 100 . In the installed state, the end of the positioning portion 440 is inserted into the corresponding middle recess.

[0116] The positioning portion 440 can provide further positioning for the protection portion 420 to reduce shaking during hoisting and transportation.

[0117] In addition, an avoidance portion 412 is formed on the overlapping portion 410. The avoidance portion 412 is a cutout formed on the overlapping portion 410 for avoiding structures such as the cover plate 103 to avoid interference.

[0118] The present application also proposes a chiller, which includes a compressor 100 and a heat exchange component. The compressor 100 is used to compress a low-temperature and low-pressure refrigerant fluid into a high-temperature and high-pressure refrigerant fluid; the heat exchange component includes an evaporator 210 and a condenser 220. The input end of the compressor 100 is connected to the evaporator 210, and the output end is connected to the condenser 220 to realize the circulation of the refrigerant.

[0119] A support assembly is preset on the outer wall of the evaporator 210, and a plurality of connecting seats 110 are formed at the bottom of the compressor 100 for connecting and fixing with the support assembly.

[0120] A valve assembly 102 and / or a pipe assembly 101 are arranged on the outer wall of the compressor 100, and a protective member 400 is fixed to the support assembly or the compressor 100. The protective member 400 is configured to at least partially cover the outside of the pipe assembly 101 and / or the valve assembly 102, so as to protect the pipe assembly 101 and / or the valve assembly 102.

[0121] The protection element 400 may be provided in any of the following ways.

[0122] Method 1, the protective member 400 includes a protective outer cover and a lap portion 410 connected to the bottom of the protective outer cover, the lap portion 410 is fixed on the connecting seat 110 or the supporting assembly, and the protective outer cover is arranged on the outside of the valve assembly 102 and / or the pipe assembly 101 to protect the surrounding side of the valve assembly 102 / or the pipe assembly 101.

[0123] Method 2: The protective member 400 includes a lap portion 410 and a protective portion 420, wherein the protective portion 420 is a flat plate structure, and the lap portion 410 and the protective portion 420 are an integrally formed sheet metal structure.

[0124] The overlapping portion 410 is fixed to the lower surface of the supporting seat 300 and is directly connected to the lower surface of the supporting cross portion 320 . The fastener 130 fixes the connecting seat 110 , the supporting cross portion 320 and the overlapping portion 410 .

[0125] Method three: The overlapping portion 410 is fixed on the upper surface of the support seat 300 and is located between the support seat 300 and the connecting seat 110 , and the fastener 130 fixes the connecting seat 110 , the overlapping portion 410 and the supporting cross portion 320 .
