Referring to fig. 1, an embodiment of the present invention: the utility model provides an on-vehicle machine rack that charges for electric automobile, heat dissipation fan 2 that sets up on rack main part 1 and the rack main part 1, the below of rack main part 1 is provided with inlet port 3, the inside of rack main part 1 is provided with accomodates groove 4, accomodate and be provided with cut-off board 7 in the groove 4, cut-off board 7 will accomodate groove 4 and split into upper and lower two parts, cut-off board 7 top is adjustment tank 41, cut-off board 7 below is standing groove 42, standing groove 42 in-connection has piston plate 5, piston plate 5 passes through adjusting part and axial slip in standing groove 42, the inside of piston plate 5 is provided with bleeder vent 6, adjustment tank 41, be linked together between standing groove 42 and the bleeder vent 6, the air of axial slip extraction standing groove 42 through piston plate 5 and the air of compression adjustment tank 41.

In this embodiment: the electric appliance element of the vehicle-mounted charger for the electric automobile is placed at the bottom of the adjusting groove 41 to be assembled and used, when the device is used, a large amount of heat can be generated due to the fact that high-voltage alternating current is converted into direct current, the heat floats above the adjusting groove 41, the heat dissipation fan 2 is used for extracting hot air floating above the adjusting groove 41, external air is sucked from the air inlet hole 3 to enter the placing groove 42, and the device is made to complete a heat dissipation cycle.

However, the hot air floating above the adjusting groove 41 is away from the heat dissipating fan 2 by a distance, and since the suction force of the heat dissipating fan 2 is gradually reduced from the adjusting groove 41 to the placing groove 42, the hot air near the placing groove 42 may escape from the interior of the cabinet main body 1 without being sucked out, and the external air entering from the air inlet 3 is slowly entered, which results in poor heat dissipating effect, by arranging the piston plate 5 inside the placing groove 42, the piston plate 5 is pulled back and forth by the adjusting member, the air of the placing groove 42 is extracted by the axial sliding of the piston plate 5, the external air is introduced into the interior of the placing groove 42 to be cooled down at an accelerated speed, and the air of the adjusting groove 41 is compressed, the hot air floating above the adjusting groove 41 is pushed to a position closer to the heat dissipating fan 2, thereby ensuring that the heat dissipating fan 2 can extract the hot air more quickly during air draft, and by the cooperation of the piston plate 5 with the heat dissipating fan 2 and the air inlet 3, so that the device has good heat dissipation effect.
