This anisotropic conductive film, which is capable of reliably inhibiting the occurrence of a short circuit, while reducing the conduction resistance of a connection structure that is anisotropicallyconductively connected, has a structure wherein conductive particles 3 with insulating particles, each of which is obtained by having insulating particles 2 adhere to the surface of a conductive particle 1, are dispersed in an insulating resin layer 5. With respect to the conductive particles 3 with insulating particles in this anisotropic conductive film, the number of insulating particles 2 in contact with a conductive particle 1 in the film thickness direction is smaller than the number of insulating particles 2 in contact with the conductive particle 1 in the film surface direction. The number of insulating particles overlapping conductive particles in a plan view of one of the front and back surfaces of this anisotropic conductive film is preferably smaller than the number of insulating particles overlapping conductive particles in a plan view of the other surface.

The invention relates to a direct contact type fluid ice slurry generator and a preparation method. The direct contact fluid ice slurry generator includes an ice slurry extraction cylinder and a nozzle group, and the ice slurry extraction cylinder has an ice slurry outlet; The nozzle group includes a brine nozzle for spraying brine and an ice-making working medium nozzle for spraying ice-making working fluid, and both the brine nozzle and the ice-making working medium nozzle are arranged on the ice slurry making cylinder , the brine nozzle and the ice-making working medium nozzle are oppositely arranged so that the input brine and ice-making working medium collide; the brine nozzle and the ice-making working medium nozzle are located above the ice slurry outlet, so that the corresponding The nozzle is located above the ice slurry layer during operation. The brine sprayed by the corresponding nozzles collides with the ice-making working medium to increase the mixing degree of the two and improve the heat transfer efficiency. At the same time, during the mixing and collision process, the ice crystals will become smoother in shape and more uniform in size, which reduces the flow resistance of ice slurry, makes ice slurry have better fluidity, and reduces the transportation load.
