Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

An embodiment of the utility model provides a pair of dysmorphism heat abstractor, as shown in fig. 1, heat abstractor includes first radiating piece 10, and first radiating piece 10 includes bottom surface laminating portion 11 and the retention portion 12 of buckling, and bottom surface laminating portion can closely laminate with the camera mainboard, and the edge of the retention portion of buckling is equipped with through-hole 13 for be connected with camera shell maintenance, and wherein, bottom surface laminating portion and with the retention portion of buckling encircle jointly and form a three-dimensional holding breach 14, the overall dimension and the step motor overall dimension of holding breach match to during making holding step motor, step motor and first radiating piece in close contact with.

Generally, the overall profile and size of the first heat dissipation element can be adjusted according to the acceptable space inside the camera, and the heat dissipation effect of the heat dissipation element on the camera is more obvious when the size of the heat dissipation element is relatively larger. However, in many current cameras with stepping motors, the main heat source of the camera comes from the main chip device on the motherboard, the stepping motor does not generate much heat because the shell of the stepping motor is made of metal and the motor is in a standby state for a long time, and if the heat dissipation member can be in close contact with the stepping motor, the heat on the heat dissipation member can be absorbed by the stepping motor, so that the camera can obtain a better heat dissipation effect.

It should be further noted that, as shown in fig. 1, the receiving notch 14 is a relatively rough design, and under the condition that the sheet metal process and the cost allow, the shape of the receiving notch 14 may be further matched according to the stepping motor inside the camera, for example, to implement the fitting with the curved shape of the stepping motor, or to extend the bent fixing portion of the first heat dissipating element to a certain extent, so as to implement the local or most of the close inclusion effect of the step click, so as to further exert the heat dissipating function of the stepping motor.
