[0034] Embodiment 1

[0035] Referring to Figures 1 to 4 , as an optional embodiment of the present application, this embodiment discloses a heat dissipation device for electromechanical equipment, including a frame 1, the frame 1 includes a base 101, and a plurality of limiting rods 102 are arranged on the base 101; a circulation channel for the cooling medium to flow is arranged on the base 101, and at the same time, air flow holes are arranged, and a circulation fan 8 is arranged in the air flow holes;

[0036] The heat dissipation device further includes a heat exchange module 2, which includes a plurality of first heat exchange plates 201. A second heat exchange plate 202 is provided between any two adjacent first heat exchange plates 201, that is, the first heat exchange plates 201 and the second heat exchange plates 202 are stacked crosswise. The first heat exchange plates 201 and the second heat exchange plates 202 have exactly the same shape and are stacked coaxially to ensure the flatness of the outer surface;

[0037] The first heat exchange plates 201 and the second heat exchange plates 202 are connected by a vacuum diffusion welding process.

[0038] An air vent hole is provided in the middle of the first heat exchange plate 201, and an air vent hole is also provided on the second heat exchange plate 202. Each of the air vent holes is coaxially penetrated in sequence to form an air flow channel 7, and the air flow channel 7 is coaxially penetrated with the air flow holes on the base 101;

[0039] At the same time, a liquid inlet hole 203 and a liquid outlet hole 204 are provided on the first heat exchange plate 201, and a liquid inlet hole 203 and a liquid outlet hole 204 are provided on the second heat exchange plate 202. The liquid inlet hole 203 and the liquid outlet hole 204 are respectively arranged on both sides of the air vent hole, and the included angle between the liquid inlet hole 203 and the liquid outlet hole 204 is 180°;

[0040] Connecting ear plates are also provided on the first heat exchange plates 201 and the second heat exchange plates 202. Limiting holes 11 are provided on the connecting ear plates, and the limiting holes 11 on the same side are coaxially penetrated. The limiting rod 102 is adapted to the limiting holes 11, and a fastening nut 12 is provided on the limiting rod 102, so as to realize the stable connection between the frame 1 and the heat exchange module 2;

[0041] A first heat exchange flow channel 5 is provided on the first heat exchange plate 201. The first heat exchange flow channel 5 includes a plurality of arc-shaped flow channels in an arc structure. The liquid inlet hole 203 and the liquid outlet hole 204 are respectively arranged at both ends of each arc-shaped flow channel, and each arc-shaped flow channel is respectively communicated with the liquid inlet hole 203 and the liquid outlet hole 204;

[0042] The second heat exchange flow channel 6 includes a plurality of linear flow channels; each of the linear flow channels is arranged radially around the axis of the second heat exchange plate 202; the inlet ends of each of the linear flow channels are respectively communicated with the air flow channel 7, and the outlet ends of each of the linear flow channels are open;

[0043] Adopting the above structure can, on the one hand, make the most of the space on the first heat exchange plates 201 and the second heat exchange plates 202, thereby increasing the flow rate and improving the heat exchange efficiency;

[0044] Secondly, the first heat exchange plate 201 is in direct contact with the second heat exchange plate 202, so heat can be quickly transferred through the first heat exchange plate 201 and the second heat exchange plate 202. Moreover, since the first heat exchange plates 201 are arranged on both the upper and lower sides of the second heat exchange plate 202, synchronous heat exchange can be achieved through the two first heat exchange plates 201, further improving the heat exchange efficiency.

[0045] Finally, in the above structure, by reducing the diameter of the flow channel, it can be designed as a microchannel, which can further improve the flow capacity. And since there are multiple independent channels, in the case of partial blockage of some channels, the entire set of equipment can still operate normally, highly improving the reliability and stability of the equipment.

[0046] It should be noted that one heat exchange module 2 can be set for the entire set of equipment, or multiple heat exchange modules 2 can be set. If more than two heat exchange modules 2 are set, then each heat exchange module 2 is successively connected in series on the frame 1. At the same time, a gasket 10 is arranged between any two adjacent heat exchange modules 2. After installation, each liquid inlet hole 203 penetrates coaxially, and each liquid outlet hole 204 also penetrates coaxially, and each ventilation hole also penetrates coaxially. Meanwhile, the gap between adjacent heat exchange modules 2 is sealed by the gasket 10.

[0047] An adjusting plate 13 is also arranged on the top of the frame 1. The adjusting plate 13 closes the outlet end of the air flow channel 7, and a number of exhaust holes 14 are arranged on the adjusting plate 13.

[0048] Through the arrangement of the adjusting plate 13 and the exhaust holes 14, the size of the outlet end of the air flow channel 7 can be reduced, thereby limiting the flow rate at its outlet end and forcing more hot air to enter the second heat exchange flow channel 6, which is beneficial to improving the adjustability of the equipment.

[0049] Secondly, the adjusting plate 13 with different specifications of exhaust holes 14 can be replaced according to needs, so as to adjust the air entering the second heat exchange flow channel 6 to meet the adjustment requirements of different temperatures.

[0050] The heat dissipation device further includes a circulation module and a cooling box 9. The circulation module includes a circulation pipe 16. The two ends of the circulation pipe 16 are respectively connected to the liquid inlet channel 3 and the liquid outlet channel 4. At the same time, a circulation pump 15 and a cooling box 9 are also arranged on the circulation pipe 16. The outlet end of the circulation pipe 16 is communicated with the liquid inlet channel 3, and its inlet end is communicated with the liquid outlet channel 4.

[0051] A number of heat conducting plates 17 are arranged in the cooling box 9. Each heat conducting plate 17 is respectively connected to the inner wall of the cooling box 9, and a number of through holes 18 for the cooling medium to flow through are arranged on each heat conducting plate 17.

[0052] In the above structure, through the heat conduction plate 17, the high temperature in the middle of the cooling box 9 can be quickly transferred to the inner wall of the cooling box 9, and finally conducted to the cold air in the basement or the foundation pit through the inner wall of the cooling box 9, which is beneficial to improving the heat conduction efficiency.

[0053] During use, the heat dissipation device is arranged on the top of the electromechanical equipment. At the same time, the hot air inside the electromechanical equipment is drawn into the air flow channel by the circulation fan. Part of the gas entering the air flow channel is discharged from the outlet end of the air flow channel, and part enters the second heat exchange flow channel. At the same time, the circulation module inputs the cooling water in the cooling box into the first heat exchange flow channel, and cools the hot air through the first heat exchange flow channel and the second heat exchange flow channel. The heat-exchanged cooling water flows back into the cooling box again, and the cooled cold air is directly exhausted. Since the cooling box is arranged in the basement or the foundation pit, the cooling box is cooled through the natural low-temperature environment, thereby reducing the temperature of the electromechanical equipment.

[0054] Compared with the prior art, in this application, the hot air is cooled through the cooperation of the first heat exchange flow channel and the second heat exchange flow channel. The first heat exchange flow channel and the second heat exchange flow channel are integrated in the heat exchange module, which can effectively increase the contact area between the first heat exchange flow channel and the second heat exchange flow channel and improve the heat dissipation efficiency.

[0055] Secondly, arranging the cooling box in the basement or the foundation pit can make full use of the natural low-temperature environment, effectively ensure the cooling effect in summer, and at the same time, it can also effectively reduce the energy consumption of the whole set of equipment, which is beneficial to reducing the operation cost of the equipment.

[0056] The above are only the preferred embodiments of this application, and do not limit the patent scope of this application accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of this application, or directly or indirectly applied in other related technical fields, shall be included in the patent protection scope of this application by the same token.
