Description of the invention G) Creation field Creation is a cooling device and method for computer interface cards. Among them, the advancement of technology, the speed of computer processing data—degrees—multiply and increase. The key point is that the computer's central processing unit (CPU), such as Intel's main brain 4 central processor PentiUD1 4 can reach the speed 丨· 76 Hz, and electrical ^ _ and computer interface cards must also be improved in order to cooperate with it. ^ Female interface cards are necessary to match the speed of the CPU and meet the user's requirements. The chip processing data on the computer interface card is processed. The accuracy of the data is ft, so the thermal energy generated is greatly increased. In this case, the efficient heat dissipation becomes important. Knowing the computer interface card chip: The method is to place a chip on the chip. Radiator (such as extruded aluminum), reuse 1. The heat energy transmitted to the radiator by the μ chip is exhausted with the air flow provided by the fan. However, if the fan fails and the speed decreases or stops, the chip will be damaged due to 'Computer interface cards are also unusable. For those unfamiliar with computer recognition, the entire computer must be sent for repair. Even for users who are familiar with computers, they must also replace the computer interface cards themselves. This design is inconvenient if the user is dealing with some emergency cases, when it is not allowed to disassemble the boot case for maintenance. An author found that the part of the chip that is in contact with the computer interface card, due to the high temperature caused by the contact. If this part of the thermal energy is effectively removed from the other side of the computer interface card, it will help the computer interface card's heat dissipation effect. Therefore, the computer interface card cooling device and method of this case are created. The following is a description of this case. Page 4 1240857
