The invention provides a rapid-conduction indirect liquid cooling heat radiation structure combining with a micro-channel, and the structure comprises a liquid cooling cold plate with a snakelike liquid cooling channel inside, a thermal conduction film and a heat radiation copper block, wherein the thermal conduction film and the heat radiation copper block are sequentially disposed at the bottomof the liquid cooling cold plate in a manner of being corresponding to the position of a big power consumption device. The flowing direction of the snakelike liquid cooling channel correspondingly passes through a space above the position of the big power consumption device, and the interior of the snakelike liquid cooling channel is provided with micro-channel heat radiation teeth corresponding to the big power consumption device. The interior of a snakelike channel indirect liquid cooling cold plate is combined with the micro-channel heat radiation teeth, and a conduction heat radiation copper block structure is embedded, thereby improving the thermal conduction efficiency from a chip device to the liquid cooling cold plate and the heat exchange performance of the liquid cooling cold plate, solving the problems that the limited heat exchange area of a conventional snakelike channel liquid cooling cold plate causes the insufficient heat radiation and the thermal conduction efficiencyfrom a chip to a cold plate is not high, and overall improving the heat radiation efficiency of a reinforced printed board card.
