The base 11 includes a first side end 11a and a second side end 11b, it can be understood that the first side end 11a and the second side end 11b are adjacent to each other, wherein the first side end 11a is provided with a cylindrical containing groove, the lens 12 is adhered in the containing groove through a back adhesive, one end of the flexible circuit board 13 is connected to the second side end 11b, one end of the flexible circuit board 13 is electrically connected to the lens 12, and the other end of the flexible circuit board 13 is used for electrically connecting to a motherboard to realize data transmission between the motherboard and the lens 12, wherein the first side end 11a and the second side end 11b are adjacent to each other, so that the extending direction of the flexible circuit board 13 is perpendicular to the lens 12, and the structure of the camera module 1 is further optimized. Of course, in other embodiments, the first side end 11a and the second side end 11b may be oppositely disposed.
Wherein, the base 11 is a square column shape, which is convenient for the layout of the camera module 1 in the mobile terminal. Of course, in other embodiments, the base 11 may also be cylindrical or other shapes.
Wherein, according to the actual heat dissipation requirement, the heat absorption heat sink 2 can be disposed on the outer surface of the lens 12, the connection between the lens 12 and the base 11, the outer surface of the base 11, and the flexible circuit board 13.

Further, the shape of heat absorption radiating piece 2 and the shape phase-match of module 1 of making a video recording, when the heat of module 1 of making a video recording reached the uniform temperature, the heat absorption heat-retaining material in the heat absorption radiating piece 2 absorbs heat, heat-retaining and the heat dissipation to the heat on the module 1 of making a video recording, comes to cool down the module 1 of making a video recording.
The heat absorption and dissipation member 2 comprises a mixed material with material properties of heat absorption, heat storage and dissipation functions, and the mixed material comprises a heat absorption and storage material and a heat conduction and dissipation material; the heat conduction and radiation material is used for transferring heat on the camera module 1 to the heat absorption and heat storage material, namely the heat conduction and radiation material can accelerate the transfer of heat in the camera module 1; the heat absorption and heat storage material is used for absorbing and storing heat on the camera module 1 and storing heat conducted by the heat conduction and heat dissipation material. The heat absorption and heat storage material in the mixed material is a phase change energy storage material consisting of polyethylene glycol and silicon dioxide, the mass ratio of the polyethylene glycol to the silicon dioxide is 1:1-9:1, and the mass ratio can be selected according to requirements. The specific process for manufacturing the heat absorption and heat storage material can be as follows: adding polyethylene glycol into silica sol with a certain concentration, and dripping CaCl after the polyethylene glycol is completely dissolved2The coagulant solution is mixed with the mixture under strong stirring,allowing the gel to carry out a gelation reaction, and standing to form a gel with a three-dimensional network structure; and (3) drying the gel in an oven at 80 ℃ for 24-28 hours by blowing, and then cooling to room temperature to obtain the mixed material consisting of a plurality of microcapsules taking the gelled silicon dioxide as capsule walls and the emulsified polyethylene glycol as capsule cores. The polyethylene glycol in the core of the microcapsule is a phase change energy storage material, that is, the microcapsule can gradually convert the polyethylene glycol in the core from a solid state to a liquid state by gradually absorbing heat to store the heat, and similarly, when the heat absorbed by the microcapsule is gradually reduced, the polyethylene glycol in the core is also gradually converted from the liquid state to the solid state to dissipate the stored heat, wherein the temperature of the polyethylene glycol in the liquid state is not high, that is, the absorbed heat is used for phase change, and the process of converting the polyethylene glycol from the liquid state to the solid state is a slow heat dissipation process, so that the heat-absorbing heat dissipation member 2 including a plurality of microcapsules can avoid that the absorbed heat is directly transferred to surrounding shell materials of the camera 100 in a short time to cause overhigh temperature of the mobile phone shell. Furthermore, the capsule wall made of the silicon dioxide is arranged, so that the liquid polyethylene glycol can be ensured not to flow out of the microcapsule, and therefore, in the process that the polyethylene glycol in the capsule core is gradually converted from a solid state to a liquid state, the microcapsule is gradually changed from hard to soft, and the texture of the heat absorption and heat storage material is further influenced to be changed from hard to soft. Use in among the combined material heat conduction heat dissipation material is graphite for the example, because the heat conductivity of graphite is good, so graphite can be faster with heat conduction extremely carry out the heat storage on the heat absorption heat-retaining material, graphite is good in the radiating effect in X, Y side in addition, so graphite can also avoid directly giving off the heat to when camera 100's the shell material around, improve combined material's radiating rate. Before the mixed material is formed by mixing, the heat-conducting and heat-dissipating material and the heat-absorbing and heat-storing material in the form of gel need to be stirred strongly to obtain corresponding powders respectively, namely the mixing process is to mix the heat-conducting and heat-dissipating material in the form of powder and the heat-absorbing and heat-storing material in the form of powderA process; the microcapsules in the heat absorption heat storage material are far smaller than the heat absorption heat storage material which is powder, so that the heat absorption heat storage material which is powder obtained after strong stirring still contains a plurality of complete microcapsules, and therefore the heat absorption heat storage material which is powder still has the heat absorption and heat storage functions, and the mixed material formed after mixing still has the heat absorption, heat storage and heat dissipation functions.
