For example, the motor, cooling fan, inverter and power module in the electromechanical equipment may be installed at the bottom of the equipment. Therefore, the bottom of the electromechanical equipment is the main source of heat and noise.

[0003] Existing heat dissipation mostly uses air cooling to speed up the air flow rate in electromechanical equipment, allowing the flowing gas to take away the heat and achieve cooling.

[0065] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0066] The core idea of ​​the embodiment of the present invention is to place the electromechanical equipment on a base, and use a shielding part to shield the base, while forming an inner and outer cavity in the shielding part, and supplying cold water to the inner cavity through a circulating cooling water tank, so that the cold water exchanges heat with the bottom of the electromechanical equipment to cool the electromechanical equipment, and the hot water after the heat exchange will enter the outer cavity and flow back to the circulating cooling water tank. Therefore, on the one hand, the cooling effect of the electromechanical equipment is guaranteed by water cooling, and on the other hand, the inner and outer cavities present a situation of cold water inside and hot water outside, and the density of water flows with different temperatures is different. The noise is greatly reduced after passing through the two different density water flows and the shielding part, so the overall heat dissipation and cooling effect is obvious.

[0067] like Figures 1 to 11As shown, a low-noise heat dissipation device for electromechanical equipment provided by an embodiment of the present invention includes a base 1, a shielding portion 2, a circulating cooling water tank 3 and a driving portion 4. The base 1 is supported below the electromechanical equipment. The shielding portion 2 is arranged around the base 1, and the shielding portion 2 is internally formed with an inner cavity 201 and an outer cavity 202 that are interconnected; wherein the inner cavity 201 is close to the base 1, and the outer cavity 202 is far away from the base 1, and a spiral guide plate 21 is wound around the inner cavity and the outer cavity. The water outlet 31 of the circulating cooling water tank 3 is connected to the inner cavity 201, and the water inlet 32 ​​is connected to the outer cavity 202. As a result, cold water can flow from the water outlet 31 into the inner cavity 201 and be drained through the spiral guide plate 21, so that after heat exchange with the bottom of the electromechanical equipment, it flows to the water inlet 32 ​​connected to the outer cavity 202, and then flows back to the circulating cooling water tank. The driving part 4 is vertically arranged at the bottom of the base 1, and the power output end of the driving part 4 is connected to the shielding part 2 to drive the shielding part 2 to move back and forth in the vertical direction, thereby shielding or exposing the bottom of the electromechanical equipment.

[0068] like Figure 3 and Figure 6 As shown, in this embodiment, preferably, the base 1 includes an assembly plate 11, a placement plate 12 and a movable limiting device 13. Specifically, the assembly plate 11 is a rectangular plate, which is carried under the electromechanical equipment to serve as the installation base of the electromechanical equipment; and a limiting groove 111 is provided on the assembly plate 11 in the horizontal direction to match the movable limiting device 13. The placement plate 12 is arranged under the assembly plate 11 and supported by a support column 120, and a movable hole 121 is provided at a position corresponding to the limiting groove 111 on the placement plate 12, and a sliding groove 122 is provided in the movable hole 121 in the horizontal direction to match the movable limiting device 13.

[0069] like Figure 7 As shown in FIG. 1 , in this embodiment, the movable limiting device 13 includes a movable seat 131, a limiting plate 132, a slide plate 133 and a movable rod 134. Specifically, the movable seat 131 is movably arranged in the movable hole 121 along the horizontal direction. The limiting plate 132 is arranged on a first side (i.e. Figure 7 The slide plate 133 is disposed on the second side (i.e. the left side) of the movable seat 131 and is slidably matched with the limiting groove 111. Figure 7 The moving rod 134 is tilted at the bottom of the movable seat 131 and matches the extrusion rod 210 installed on the shielding part 2. When in use, the shielding part 2 is driven to rise by the driving part 4, thereby driving the extrusion rod 210 to abut against the moving rod 134, and then the movable seat 131 is driven by the moving rod 134 to move horizontally in the movable hole 121.

[0070] In the above embodiment, preferably, the moving rod 134 includes two parallel sub-moving rods, both ends of the sub-moving rods are vertical sections, and the middle is an inclined section, so that an extrusion hole 135 with vertical ends and an inclined middle is formed between the two sub-moving rods. Specifically, the extrusion rod 210 is located below the extrusion hole 135 and corresponds to the bottom opening of the extrusion hole 135, so that the extrusion rod 210 can enter or leave the extrusion hole 135 from the bottom opening. Figure 5 As shown, when the extrusion rod 210 enters the extrusion hole 135 from the bottom opening, the extrusion rod 210 squeezes the inclined section of the sub-movable rod, thereby driving the movable seat 131 to move in the movable hole 121 close to the shielding portion 2. At this time, the slide plate 133 slides out of the slide groove 122, and when the movable seat 131 moves to the extreme position, the limiting plate 132 is inserted into the corresponding limiting groove 111, thereby realizing the automatic installation and positioning of the assembly plate 11 and the placement plate 12. In addition, preferably, the length of the slide plate 133 is greater than the maximum moving distance of the movable seat 131 in the movable hole 121, so that when the limiting plate 132 is inserted into the limiting groove 111, the slide plate 133 can block the gap between the movable seat 131 and the movable hole 121.

[0071] like Figure 7 As shown, preferably, the movable limiting device 13 further includes a fixed plate 136 and an elastic telescopic rod 137. The fixed plate 136 is fixed to the bottom of the placement plate 12 to provide a mounting base for the elastic telescopic rod 137. Accordingly, the elastic telescopic rod 137 is arranged on one side of the fixed plate 136 in the horizontal direction, and the elastic telescopic end of the elastic telescopic rod 137 always abuts against the movable rod 134. Thus, when the movable seat 131 moves in the movable hole 121, due to the elasticity of the elastic telescopic rod 137, the extrusion hole 135 and the movable rod 134 can remain stable, so the extrusion rod 210 can smoothly enter the extrusion hole 135 during the upward movement process.

[0072] like Figure 3 and Figure 4 As shown, in this embodiment, the shielding portion 2 is a rectangular frame, and an inner cavity 201 and an outer cavity 202 are formed inside the rectangular frame. The inner cavity 201 and the outer cavity 202 are connected to form a U-shaped cavity together (it can also be V-shaped in other embodiments). The spiral guide plate 21 is wound in the inner cavity 201 and the outer cavity 202, which is used to drain the liquid and increase the residence time of the liquid in the U-shaped cavity, thereby improving the heat exchange effect between the cold water and the bottom of the electromechanical equipment. In addition, a U-shaped extrusion rod 210 and a rectangular plate-shaped top block 220 are formed on the inner wall of the shielding portion 2. Therefore, as the driving portion 4 drives the shielding portion 2 to rise, the extrusion rod 210 cooperates with the moving rod 134, and the top block 220 cooperates with the piston inflation portion 6 (described in detail below).

[0073] like Fig. 9As shown, in this embodiment, the driving part 4 includes a driving motor 41, a screw rod 42, a nut 43, a connecting block 44 and a connecting plate 45. Among them, the driving motor 41 is fixed to the bottom of the placement plate 12, the screw rod 42 is connected to the power output end of the driving motor 41 in the vertical direction, the nut 43 is threadedly connected to the screw rod 42, the connecting block 44 is sleeved on the outside of the nut 43 and fixedly connected to the shielding part 2, and the connecting plate 45 is fixed to the bottom of the screw rod 42 and supported on the working surface. Thus, when the driving motor 41 rotates, the screw rod 42 is driven to rotate, so that the rotational motion is converted into the vertical movement of the connecting block 44 through the threaded cooperation between the screw rod 42 and the nut 43, and then the shielding part 2 is driven to rise or fall through the connecting block 44. It can be understood that the specific structural form of the driving part 4 in this embodiment is only one of the embodiments. In other embodiments, the structure of the driving part 4 can be adaptively adjusted as needed, as long as it can drive the shielding part 2 to move up and down relative to the base 1.

[0074] like Figure 2 and Figure 6 As shown, in the above embodiment, preferably, the low-noise heat dissipation device further includes a sealing airbag 5 and a piston inflation portion 6. The sealing airbag 5 is disposed between the base 1 and the shielding portion 2 to block the gap between the base 1 and the shielding portion 2 in an inflated state. The piston inflation portion 6 is disposed at the bottom of the base 1 and connected to the sealing airbag 5 to inflate the sealing airbag 5.

[0075] Specifically, Figure 8 As shown, in this embodiment, the piston inflation portion 6 includes a piston frame 61, a piston 62 and a first elastic member 63. The piston frame 61 is fixed to the bottom of the placement plate 12, and the hollow inner cavity 610 of the piston frame 61 is connected to the sealing airbag 5 through a pipe 64. The piston 62 includes a piston head 621 and a piston rod 622, wherein the piston head 621 is a rectangular plate-like structure, and the piston head 621 is movably arranged in the piston frame 61 along the vertical direction, and the piston rod 622 is connected to the end face of the piston head and protrudes out of the piston frame 61. The first elastic member 63 is arranged in the piston frame 61, and its two ends are respectively abutted against the inner wall of the piston frame 61 and the piston head 621. As shown Figure 2 As shown, the top block 220 on the shielding part 2 corresponds to the bottom of the piston rod 622. The top block 220 contacts the bottom of the piston rod 622 as the shielding part 2 moves upward, thereby driving the piston head 621 to move upward in the hollow inner cavity of the piston frame 61, so that the gas stored in the hollow inner cavity is filled into the sealing airbag 5 through the pipeline 64, so that the sealing airbag 5 gradually expands to an inflated state. The expansion of the sealing airbag 5 can support and fill the gap between the base 1 and the shielding part 2, so that the bottom of the electromechanical equipment is completely covered and shielded, and its sealing and sound insulation performance is more ideal.

[0076] like Figure 1and Figure 2 As shown, in the above embodiment, preferably, the low-noise heat dissipation device further includes an auxiliary heat dissipation portion 7. The auxiliary heat dissipation portion 7 includes a plurality of auxiliary heat dissipation components 70, each of which is disposed on one side of the outer wall of the shielding portion 2 for auxiliary heat dissipation. Specifically, as Fig.10 and Fig.11 As shown, the auxiliary heat dissipation component 70 includes a plurality of flexible thermal pads 71, a plurality of thermal conductive plates 72 and a pushing portion 73. The first end of each flexible thermal pad 71 is connected to the outer wall of the shielding portion 2, and the plurality of flexible thermal pads 71 ​​are evenly distributed on one side of the outer wall of the shielding portion 2. Correspondingly, each thermal conductive plate 72 is respectively connected to the second end of each flexible thermal conductive pad 71, so that each thermal conductive plate 72 can be expanded or retracted with the deformation of the flexible thermal conductive pad 71. The pushing portion 73 is arranged on the outer wall of the shielding portion 2, and the pushing portion 73 includes a plurality of pushing posts 7311, and the plurality of pushing posts 7311 correspond to the plurality of thermal conductive plates 72, so that the plurality of pushing posts 7311 can push the plurality of thermal conductive plates 72 to expand as the shielding portion 2 moves upward.

[0077] It is understandable that when the heat conductive plate 72 is unfolded, the hot water flowing in the outer cavity 202 will transfer heat to the flexible thermal pad 71 through the outer wall of the shielding portion 2, and then transfer heat to the heat conductive plate 72 through the flexible thermal pad 71, so as to quickly dissipate heat through the unfolded heat conductive plate 72.

[0078] In the above embodiment, preferably, the pushing portion 73 includes a pushing frame 731, a connecting rod 732, a guide rod 733 and a second elastic member 734. The pushing frame 731 is composed of a plurality of pushing columns 7311 and a plurality of pushing rods 7312 connected to each other into a preset shape (a rectangular shape in this embodiment), and the plurality of pushing columns 7311 correspond to the plurality of heat conducting plates 72. The first end (i.e. Fig.10 The left end of the second elastic member 734 is connected to the push rod 7312, and the second end is fixed with a guide sleeve 7321, and the axial direction of the guide sleeve 7321 is in the vertical direction. The guide rod 733 is inserted into the guide sleeve 7321, and the bottom of the guide rod 733 is provided with a bottom plate 7331, and the top of the guide rod 733 is provided with a top plate 7332, and the bottom plate 7331 is fixedly connected to the outer wall of the shielding part 2. The second elastic member 734 is sleeved on the guide rod 733, and the two ends are respectively against the guide sleeve 7321 and the top plate 7332. It can be understood that when the driving part 4 drives the shielding part 2 to rise, the bottom plate 7331 will abut against the guide sleeve 7321, and drive the push frame 731 to move upward through the push rod 7312, thereby pushing the multiple heat conducting plates 72 to unfold through the multiple push columns 7311. On the contrary, when the shielding portion 2 descends, the push rod 7312 gradually descends, and the heat conducting plate 72 returns to its original position under the action of gravity.

[0079] In addition, in the above embodiment, preferably, the connecting rod 732 is a magnetic rod, and, referring to Figure 5 As shown, a magnetic plate 14 is provided on the outside of the base 1, and the connecting rod 732 has the same magnetic properties as the magnetic plate 14. It can be understood that when the driving part 4 drives the shielding part 2 to move upward, the connecting rod 732 and the heat conducting plate 72 are correspondingly driven to move upward. When the connecting rod 732 moves to the top of the magnetic plate 14, the magnetic repulsion between the connecting rod 732 and the magnetic plate 14 controls the guide sleeve 7321 and the connecting rod 732 to move upward along the guide rod 733. At this time, the second elastic member 734 is compressed, thereby reaching a balanced state through the repulsive force and the elastic force, so that the pushing part 73 is in a stable state, ensuring the working stability of the heat conducting plate 72.

[0080] The working principle of the low-noise heat dissipation device according to the embodiment of the present invention is described in detail below:

[0081] Place the assembly plate 11 at the bottom of the electromechanical equipment on the placement plate 12, and then control the drive motor 41 to start, so as to drive the screw rod 42 to rotate, and through the threaded cooperation between the screw rod 42 and the nut 43, the rotational motion is converted into the vertical movement of the connecting block 44, and then the shielding part 2 is driven to rise through the connecting block 44 to surround and shield the bottom position of the electromechanical equipment installed on the assembly plate 11. At this time, the circulating cooling water tank 3 is controlled to work, and the cold water discharged from the water outlet 31 of the circulating cooling water tank 3 flows into the inner cavity 201 and is drained through the spiral guide plate 21, so as to exchange heat with the bottom of the electromechanical equipment and then flow to the water inlet 32 ​​connected to the outer cavity 202, and then flow back to the circulating cooling water tank. Since the water flows along the spiral guide plate 21, the flow path of the water flow is increased, and the residence time of the water flow in the cavity is increased, so that the cold water can fully absorb the heat dissipated by the electromechanical equipment, thereby making the shielding part 2 appear as cold water inside and hot water outside. The density of water flows with different temperatures is different. The noise is greatly reduced after passing through the two water flows with different densities and the shielding part 2. The hot water flows back to the circulating cooling water tank 3 through the water inlet end 32 for cooling circulation.

[0082] When the shielding part 2 moves upward, it controls the extrusion rod 210 to move upward, so as to enter the extrusion hole 135 from the bottom opening of the extrusion hole 135, and uses the inclined section of the extrusion hole 135 to control the moving rod 134 and the movable seat 131 to move close to the shielding part 2. At this time, the slide plate 133 slides out of the slide groove 122, and when the movable seat 131 moves to the extreme position, the limiting plate 132 is inserted into the corresponding limiting groove 111, so as to realize the automatic installation and positioning of the assembly plate 11 and the placement plate 12, and the slide plate 133 blocks the gap between the movable seat 131 and the movable hole 121.

[0083] When the shielding part 2 moves upward, it will also control the top block 220 to move upward, so that the top block 220 contacts the bottom of the piston rod 622, thereby driving the piston head 621 to move upward in the hollow inner cavity of the piston frame 61, so that the gas stored in the hollow inner cavity can be filled into the sealing airbag 5 through the pipeline 64, so that the sealing airbag 5 gradually expands to an inflated state, thereby supporting and filling the gap between the base 1 and the shielding part 2.

[0084] When the shielding part 2 moves upward, it will also drive the pushing part 73 to move upward. When the connecting rod 732 moves to the top of the magnetic plate 14, the magnetic repulsion between the connecting rod 732 and the magnetic plate 14 will control the guide sleeve 7321 and the connecting rod 732 to move upward along the guide rod 733. At this time, the second elastic member 734 is compressed, thereby reaching a balance state through the repulsion and elastic force, so that the pushing part 73 is in a stable state. At this time, the pushing column 7311 pushes the heat conducting plate 72 to rotate, so that the heat conducting plate 72 is unfolded and cooperates with the heat conducting pad 71 for auxiliary heat dissipation, so that the heat in the shielding part 2 can be quickly dissipated into the air, reducing the energy consumption of the circulating cooling water tank 3 and the efficiency of the cooling water.
