The invention relates to the technical field of automobile battery chargers, and provides an automobile intelligent
battery charger with an auxiliary power supply, the automobile intelligent
battery charger comprises a shell and further comprises a heat dissipation
assembly arranged on the inner wall of the shell, the heat dissipation
assembly comprises two fireproof sleeves installed at the two ends of the shell, and insulation sleeves are arranged in the two fireproof sleeves; when the heat dissipation fan is used and the heat dissipation fan body works, air between the two laminates is exhausted to the outside of the shell through the through holes, the flow speed of air around the first liquid return
pipe, the second liquid return
pipe, the heat dissipation fins and the
temporary storage box is increased, the heat dissipation effect is improved, and the heat dissipation effect is improved. By forming a liquid flowing loop, heat generated by the cable is dissipated, and the first liquid return
pipe, the second liquid return pipe, the hose and the plurality of heat dissipation fins are utilized to dissipate heat, so that damage to the cable, the power supply body and the charger body after heat accumulation is avoided, and the service life is prolonged.
