The above structure is the prior art, so it is not described in detail. A liquid outlet pipe 58 is fixedly connected to the outer wall of one side of the exhaust pump 57, and the end of the liquid outlet pipe 58 away from the exhaust pump 57 is fixedly connected to the graphene plate frame 59. The graphene plate frame 59 is provided to absorb and release the heat emitted from the outer surface of the heat exchanger body 1 in real time.

[0027] Working principle: by turning on the fan 56, air outside the air inlet 4 is sucked in, and the air is filtered through the filter plate 52 for dust. At the same time, the fan 56 cools the heat exchanger body 1 and the cold discharge pump 57. Then, the cold discharge pump 57 is turned on to allow the coolant to enter the graphene plate frame 59 through the liquid outlet pipe 58, so that the graphene plate frame 59 absorbs and releases the surface heat of the heat exchanger body 1 and dissipates the heat. Then, the coolant flows to the circulation pipe 510 and is recycled into the cold discharge pump 57 for circulation. At the same time, the vibration generated when the fan 56 and the cold discharge pump 57 are started is transmitted to the support plate 55, so that the support plate 55 moves to pull the spring damper 54 for buffering and shock absorption. When the dust on the internal filter plate 52 and the internal components are maintained after long-term use, the arc block 64 is moved by pulling the paddle 63, and the arc block 64 moves out of the limit groove 61, and then the mounting plate 62 is pulled out of the fixing frame 3, and then the filter plate 52 is pulled out of the mounting groove 51 for maintenance.
