NOVELTY - The utility model claims a high-density interconnected blind hole structure, comprising a middle layer plate, the top part part of the middle layer plate is fixedly connected with a top layer plate, the bottom of the middle layer plate is fixedly connected with a bottom layer plate, the top part of the top part of the top part of the front and back two ends are provided with a blind hole, the inner wall of the blind hole is fixedly connected with a ring sleeve, the inner part of the ring sleeve is provided with a cavity. by setting the graphene heat absorbing sleeve, the heat generated by the circuit in the blind hole can be absorbed, so as to reduce the heat of the circuit, by setting the heat conducting carbon fibre rod, the heat of the graphene heat absorbing sleeve can be transmitted, the heat is prevented from gathering in the graphene heat absorbing sleeve, so the heat is flow guiding, By setting the radiating silica gel plate, the heat of the heat conducting carbon fibre rod can be transmitted to the outside, so as to discharge the heat outwards, by setting the radiating groove, increasing the radiating silica gel plate and the air of the contact, so as to accelerate the radiating efficiency of the device.
