Abstract

The embodiment of the invention discloses an intelligent card heat dissipating device and a manufacturing method thereof, belongs to the technical field of the machinery and solves the technical problem of bad heat dissipating effect of the card holder of the existing intelligent card. The intelligent card heat dissipating device comprises a heat transfer component and a heat dissipation structure which are arranged on a circuit board, wherein the heat transfer component is fixed on a first surface of the circuit board; an intelligent card is fixedly clamped on the heat transfer component in a dismountable mode; a chip of the intelligent card is pressed against the heat transfer component; the chip is electrically connected with a power consumption device on the circuit board; the heat dissipation structure is arranged between the circuit board on the periphery of the heat transfer component and a second surface of the circuit board and / or is arranged on the region on the second surface of the circuit board opposite to the position of the heat transfer component; and the positions of the second surface and the first surface on the circuit board are opposite to each other. The invention is used to reduce a temperature of the chip of the intelligent card in the working process.

Description

technical field [0001] The invention belongs to the technical field of machinery, and in particular relates to a smart card cooling device and a manufacturing method thereof. Background technique [0002] With the continuous development of electronic technology, smart cards (Smart cards) are more and more widely used in electronic equipment. [0003] A smart card is also called an integrated circuit card (Integrated Circuit card, IC). Existing smart cards mainly include contact and contactless. Contact smart cards are usually used with smart card holders. [0004] Such as figure 1 As shown, the existing smart card holder includes a reed-shaped metal sheet 21 fixed on the surface 11 of the circuit board 1, and a card holder shell 6, wherein: the card holder shell 6 is covered on the metal sheet 21, and the card holder A slot 61 is provided on the side wall of the casing 6, the smart card 3 is embedded in the slot 61 and the chip 30 on the smart card 3 abuts against the me...
