[0028] The embodiments described below with reference to the drawings are exemplary and are only used to explain the present application, and cannot be explained as a limitation of the present application.

[0029] Referring to Figures 1 to 3 The present application provides an air-cooled water chiller unit, which comprises a shell 10, a refrigeration system 20, a water system 30 and an electric control system 40, wherein:

[0030] The shell 10 includes a frame body 11, a top plate 12, and a bottom plate 13. The top plate 12 is connected above the frame body 11, and the frame body 11 is mounted on the bottom plate 13. The frame body 11, top plate 12, and bottom plate 13 are connected to form a completely enclosed shell 10. The frame body 11, top plate 12, and bottom plate 13 together enclose a receiving cavity 14. A first beam 15 and a second beam 16 are provided in the receiving cavity 14. The first beam 15 and the second beam 16 are spaced apart in the receiving cavity 14 along the direction of gravity. The first beam 15 is located above the second beam 16. The first beam 15 and the second beam 16 divide the receiving cavity 14 from top to bottom into a first chamber 141, a second chamber 142, and a third chamber 143.

[0031] The refrigeration system 20, water system 30, and electrical control system 40 are all housed within the receiving cavity 14. While ensuring their respective functions are fulfilled, the refrigeration system 20 is distributed within the first chamber 141, the second chamber 142, and the third chamber 143. The water system 30 is located between the first beam 15 and the second beam 16, and the electrical control system 40 is located between the top plate 12 and the first beam 15. This air-cooled chiller unit fully utilizes the space of the receiving cavity 14, rationally arranging the refrigeration system 20, water system 30, and electrical control system 40, minimizing the thickness of the casing 10. When the air-cooled chiller unit is placed on the door of a commercial or industrial storage cabinet, it achieves excellent cooling performance with a very small space occupancy.

[0032] In the embodiments provided in this application, the frame body 11 includes a first panel 111, a second panel 112, a third panel 113, and a fourth panel 114 connected in sequence. The first panel 111 and the third panel 113 are arranged opposite to each other, and the second panel 112 and the fourth panel 114 are arranged opposite to each other. The two ends of the first panel 111 are connected to the second panel 112 and the fourth panel 114, respectively. Similarly, the two ends of the third panel 113 are connected to the second panel 112 and the fourth panel 114, respectively. The first panel 111, the second panel 112, the third panel 113, and the fourth panel 114 enclose the main body of the receiving cavity 14. The top plate 12 and the bottom plate 13 close the two ends of the frame body 11 to form a sealed shell 10. The extension direction of the first beam 15 and the second beam 16 is the direction of the line connecting the center points of the second panel 112 and the fourth panel 114. The opposite ends of the first beam 15 and the second beam 16 are connected to the second panel 112 and the fourth panel 114, respectively, to divide the receiving cavity 14 into three chambers.

[0033] Reference Figure 3As shown, the refrigeration system 20 includes a compressor 21, a plate heat exchanger 22, a condenser 23, an electronic expansion valve 24, a first fan 25, and a second fan 26. The condenser 23 is located between the top plate 12 and the first beam 15 (i.e., within the first chamber 141). The compressor 21 and the plate heat exchanger 22 are located between the first beam 15 and the second beam 16 (i.e., within the second chamber 142). The first fan 25 and the second fan 26 are both located between the second beam 16 and the bottom plate 13 (i.e., within the third chamber 143). The refrigeration system 20 is the main component of the air-cooled chiller unit and has a relatively large number of components. All components are arranged in three chambers. When the first fan 25 and the second fan 26 are started, the space on both sides of the compressor 21 and the plate heat exchanger 22 can act as air ducts to allow cooling air to flow. This avoids the obstruction of cooling air flow caused by many components being arranged in the same chamber, which would reduce the air volume and thus effectively reduce the noise generated during unit operation.

[0034] Furthermore, the first panel 111 is provided with an air outlet 27, which is located at one end of the first panel 111 near the top plate 12, as shown in the figure. Figure 1 as well as Figure 3 As shown, the air outlet 27 is located on the part of the first panel 111 corresponding to the first chamber 141. Under the action of the first fan 25 and the second fan 26, the air flows from the third chamber 143 to the second chamber 142. Under the action of the refrigeration system 20, the air is cooled down to form cooling air, which continues to flow into the first chamber 141 and is finally sent out through the air outlet 27 to achieve heat dissipation and cooling of the product.

[0035] To achieve air cooling circulation, continue referring to... Figure 1 as well as Figure 3 As shown, two return air vents 28 are also provided on the first panel 111. The two return air vents 28 correspond to the positions of the first fan 25 and the second fan 26, respectively. Outside air enters the third chamber 143 through the two return air vents 28. Then, under the action of the first fan 25 and the second fan 26, the air is forced to flow into the second chamber 142, thereby cooling the air. The cooled air is then sent out through the air outlet 27 to dissipate heat, thus forming a cycle in which outside air enters the housing 10 for cooling, and then the cooled air is sent out. After the cooled air dissipates heat on the product, it can re-enter the housing 10 through the return air vents 28.

[0036] The air entering the housing 10 through the return air inlet 28 may carry dust particles and other impurities. In order to prevent these impurities from being carried into the housing 10 and adsorbing or sticking to the various components of the refrigeration system 20, water system 30 and electrical control system 40, causing pollution to the internal components and even affecting their normal operation, filters (not shown) are installed on both return air inlets 28. The filters can block dust particles and other impurities, preventing them from entering the housing cavity 14 with the air, and effectively avoiding the impact of impurities on heat exchange efficiency.

[0037] To ensure the operating efficiency of air-cooled chiller units, regular equipment maintenance is required. In the embodiments provided in this application, reference is made to... Figure 2 As shown, the third panel 113 includes a first cover plate 1131 and a second cover plate 1132. The first cover plate 1131 is located at one end of the third panel 113 near the bottom plate 13, corresponding to the position of the refrigeration system 20 and the water system 30. The first cover plate 1131 is detachably mounted on the third panel 113. When the equipment needs maintenance or repair, only the first cover plate 1131 needs to be removed, which facilitates the investigation of production problems and subsequent application and maintenance.

[0038] In the embodiments provided in this application, the water system 30 includes a return water inlet 31, a water pump 32, a pipe heating element 33, and a water outlet 34. The water pump 32 and the pipe heating element 33 are both located between the first beam 15 and the second beam 16 (i.e., within the second chamber 142). The return water inlet 31 and the water outlet 34 are both located on the second panel 112. (Refer to...) Figure 2 as well as Figure 3 As shown, the return port 31 and the outlet 34 are located on the second panel 112 corresponding to the second chamber 142. The return port 31 is closer to the top plate 12, and the outlet 34 is closer to the bottom plate 13. The coolant flows from the return port 31 to the water pump 32, and after being processed by the refrigeration system 20, it is discharged through the pipe heating element 33 and the outlet 34, thus realizing the heat exchange process. By placing the return port 31 and the outlet 34 on the second panel 112, the respective functions can be achieved without occupying the internal space of the housing 10, and the input and output of the coolant are more convenient.

[0039] Furthermore, the water system 30 also includes a replenishment port 35 and an expansion tank 36. The replenishment port 35 is embedded in the end of the second panel 112 near the bottom plate 13, and is closer to the bottom plate 13 than the outlet 34. The replenishment port 35 is hidden on the second panel 112, which can realize the replenishment function without occupying too much space in the unit. The expansion tank 36 is located on the second panel 112 between the top plate 12 and the first beam 15 (third chamber 143). The expansion tank 36 is connected to the water pump 32 and only occupies a small space in the first chamber 141 to realize its function.

[0040] In the embodiments provided in this application, reference is made to Figure 1 as well as Figure 3 As shown, the electrical control system 40 includes an electrical control box 41 and an electrical module 42. The electrical control box 41 is located between the top plate 12 and the first beam 15, and is arranged in the first chamber 141 in parallel with the condenser 23. The electrical module 42 includes communication, power supply and debugging functions. The electrical module 42 is embedded in the fourth panel 114 to facilitate personnel to perform electrical control and debugging.

[0041] Reference Figure 1 as well as Figure 2 As shown, the air-cooled chiller unit of this application also includes a limiting frame 17. After the frame body 11, top plate 12 and bottom plate 13 are connected in sequence to form the shell 10, the shell 10 is fixed as a whole by the limiting frame 17, which can increase the overall strength of the unit and ensure the fixation of the various components inside the shell 10.

[0042] The air-cooled chiller unit of this application rationally distributes the various components of the refrigeration system 20, water system 30 and electrical control system 40 inside the casing 10 and on various panels. Under the premise of ensuring that the unit achieves good refrigeration function, it has the advantages of high efficiency and energy saving, reduced unit space occupation, easy maintenance and repair, beautiful appearance and long service life. It is suitable for placement inside products such as energy storage cabinets for refrigeration work.
