When interior forced air cooling circulating device dismouting is maintained, pulling spacer pin 14, spacer pin 14 follows spacing downthehole roll-off, it is spacing to keep 11 to remove of shell this moment, thereby dismantle interior forced air cooling circulating system device, after the installation, under spacing spring 12's spring action, spacer pin 14 automatic sliding is downthehole in spacing, thereby fix the position that keeps shell 11, through setting up spacer pin 14 and spacing spring 12, the dismouting of the interior forced air cooling system device of being convenient for is maintained, do not need to twist the bolt many times, time saving and labor saving. The second motor 50 is turned on, the second motor 50 rotates the rotary shaft and the second fan 44, the second fan 44 sucks the external air into the cooling chamber 25, the lithium battery body 21 is cooled, the rotating shaft drives the rotating rod 46 to rotate, the rotating rod 46 is contacted with the bump 45, thereby pushing the second motor 50 to move, the second motor 50 is fixed on the ball pin 48, the ball pin 48 swings with the ball groove as the center, and returns under the elastic force of the extension spring 51, thereby realizing the continuous swing, by arranging the internal air cooling system, the external air flows into the cooling cavity 25 to cool the lithium battery body 21, by providing the extension spring 51, the ball pin 48, and the ball groove, the swing of the second motor 50 is achieved, thereby causing the second fan 44 to swing, carry out the forced air cooling to lithium cell body 21 different orientations to be convenient for cool down lithium cell body 21. Start first motor 41, first motor 41 drives the axis of rotation and rotates to drive first fan 43 and rotate, three first fan 43 passes through runner 39 and belt 40 and connects, thereby three first fan 43 rotates simultaneously, cools off fast outer water circulating system's water, through setting up outer air-cooled system, is convenient for cool off fast hot water, makes cold water circulation normal use. The first water pump 31 and the second water pump 34 are started, the first water pump 31 enables hot water in the hot water cavity 19 to flow into the cold water cavity 23 through the external circulating pipe 36, the hot water in the external circulating pipe 36 is cooled under the action of the heat dissipation plate 35 and the external air cooling system, the second water pump 34 enables cold water in the cold water cavity 23 to flow into the hot water cavity 19 through the internal circulating pipe 33, the internal circulating pipe 33 surrounds the lithium battery body 21 and takes away heat on the lithium battery body 21, through the arrangement of the external water circulating system and the internal water circulating system, the water circulation takes away heat on the lithium battery body 21, so that the lithium battery body 21 is cooled, through the arrangement of the corrugated groove 53, the contact area between the cold air and the lithium battery body 21 is increased, the heat on the lithium battery body 21 is further taken away, the air cooling system and the water cooling system are arranged, the lithium battery can be normally used, the service life of the lithium battery is prolonged.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
