[0030] The following is combined with Figure 1-3 This application is described in further detail.
[0031] Example 1
[0032] The present application provides a soundproof cover for a chiller, such as Figure 1 and Figure 2 As shown, it includes a bottom plate 1, a plurality of support rods 2 are fixedly connected to the top of the bottom plate 1, and a fixing plate 3 for installing the chiller is fixed to the top of the plurality of support rods 2. A soundproof cover 4 is also provided on the bottom plate 1, and the soundproof cover 4 completely covers the outside of the chiller, and its side wall is a hollow structure to form a heat absorption cavity 41, and the heat absorption cavity 41 is filled with cooling water.
[0033] When the chiller is working, a large amount of heat will be generated. If the heat is not dissipated in time, it may cause damage to the circuits and other components inside the unit. The soundproof cover 4 in this embodiment has a heat absorption chamber 41 filled with cooling water, which can effectively absorb the heat generated by the chiller, thereby reducing the temperature inside the soundproof cover 4, thereby protecting the chiller and preventing the circuits from burning due to overheating.
[0034] Example 2
[0035] The embodiment of the present application provides a sound insulation cover for a chiller, which further optimizes the heat dissipation structure of the sound insulation cover on the basis of embodiment 1.
[0036] Specifically, if Figure 1 and Figure 2 As shown, an open circulating water tank 5 is added below the bottom plate 1, and a water pump 6 is fixed to the side wall of the circulating water tank 5. One end of the water pump 6 is connected to the circulating water tank 5 through a water inlet pipe 61, and the other end is connected to the heat absorption chamber 41 through a water outlet pipe 62. At the same time, the heat absorption chamber 41 is also connected to the circulating water tank 5 through a return pipe 63, forming a closed circulation system.
[0037] In addition, if Figure 2 and Figure 3As shown, the circulating water tank 5 is also provided with a heat sink 7 for dissipating heat from the water in the circulating water tank 5. The specific structure of the heat sink 7 includes a rotating rod 71 rotatably arranged in the circulating water tank 5, and a plurality of stirring blades 72 are fixed on the rotating rod 71. A rotating impeller 73 is also provided in the circulating water tank 5, and a rotating shaft sleeve of the rotating impeller 73 is provided with a first bevel gear 74. A second bevel gear 75 is provided on the outer sleeve of the rotating rod 71. A transmission rod 76 is provided between the first bevel gear 74 and the second bevel gear 75, and a bevel gear 1 77 meshing with the first bevel gear 74 is provided at one end of the transmission rod 76, and a bevel gear 2 78 meshing with the second bevel gear 75 is provided at the other end.
[0038] When heat dissipation is required, the impeller 73 is first started, and the impeller 73 drives the first bevel gear 74 to rotate. Since the first bevel gear 74 is meshed with the bevel gear 1 77, it drives the transmission rod 76 to rotate. The rotation of the transmission rod 76 drives the bevel gear 2 78 to rotate, and then the second bevel gear 75 and the rotating rod 71 rotate together. The stirring blade 72 on the rotating rod 71 rotates accordingly, thereby increasing the contact area between water and air and improving the heat dissipation efficiency.
[0039] Through such a design, not only the recycling of cooling water is achieved, but also the rotation and stirring of the stirring blades 72 greatly improves the heat dissipation effect, ensuring that the chiller can operate stably for a long time.
[0040] Example 3
[0041] Based on Example 2, the embodiment of the present application further improves the structure of the circulating water tank to increase its ease of use and stability.
[0042] Specifically, if Figure 2 and Figure 3 As shown, a protective net 8 is added at the opening of the circulating water tank 5. The protective net 8 is a tubular structure, one end of which is connected to the bottom plate 1 through a first Velcro 81, and the other end is connected to the circulating water tank 5 through a second Velcro 82. This design can effectively prevent foreign debris from entering the circulating water tank 5 and blocking the water inlet pipe 61, and facilitate the disassembly and cleaning of the protective net 8.
[0043] In addition, a splash-proof pipe 9 is additionally provided on the side wall of the circulating water tank 5. The splash-proof pipe 9 includes a support pipe 91 and a water collecting pipe 92. The water collecting pipe 92 is arranged in a funnel shape (or a truncated cone shape), and its end with a smaller opening is connected to the support pipe 91, while the bottom of the support pipe 91 is connected to the circulating water tank 5. The rotating impeller 73 is arranged in the support pipe 91 and close to the top opening of the support pipe 91, and the water outlet of the return pipe 63 is arranged toward the end of the water collecting pipe 92 with a larger opening.
[0044] In order to further optimize the structure, the support pipe 91 and the water collecting pipe 92 are connected in a detachable manner, such as by threaded connection. At the same time, the bottom end of the return pipe 63 is also connected to a bellows 93, and one end of the bellows 93 is provided with a water spray pipe 94, which is arranged in a truncated cone shape, with a large diameter at one end and a small diameter at the other end. The end with a small diameter is arranged toward the rotating impeller 73, and the water spray pipe 94 is inserted into the water collecting pipe 92.
[0045] Such a design not only effectively reduces the possibility of water flowing out of the return pipe 63 splashing out of the circulating water tank 5 after hitting the rotating impeller 73, thus saving water resources; at the same time, through the adjustment of the bellows 93, the height of the water outlet of the return pipe 63 can be conveniently adjusted, thereby increasing the contact time between water and air and improving the heat dissipation effect. Moreover, the detachable design of the water collecting pipe 92 also provides great convenience for the maintenance of the rotating impeller 73.
[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
