(1) stage (1971-1973). This is the era of 4-bit and 8-bit low-level microprocessors 2. Turn on the power and start the motor (power supply voltage 380V 50Hz). The representative product is Intel 4004 processor. [3]

1971, when Intel needed, the manager or operator could regularly (for example, one year) back up and remove the produced 4004 microprocessor to integrate the arithmetic unit and controller into one chip, marking the birth of CPU; In 1978, 808

order, execution of operation, control of time and processing of data. [2]

has been developing rapidly. [1]

2. The installation of the radiator shall consider the direction conducive to heat dissipation, and heat dissipation holes shall be opened at the corresponding positions on the chassis or chassis (so that cold air enters from the bottom and hot air disperses from the top)

3. If the shell of the device is an electrode, the mounting surface is not insulated (not insulated from the internal circuit). Mica gasket must be used for insulation during installation to prevent short circuit

4. The pins of the device should pass through the radiator and drill holes on the radiator. To prevent the pin from colliding with the hole wall, a polytetrafluoroethylene sleeve shall be put on

qca = package thermal resistance from the package shell to the ambient air (degrees Celsius per watt)

tj = average die temperature (degrees Celsius)

tc = package shell temperature (degrees Celsius)

ta = ambient air temperature (degrees Celsius) is the core hardware unit for control, deployment and general operation. CPU is

5 In addition, different types of radiators have different thermal resistance under different heat dissipation conditions, which can be modified during design. That is, in practical application, the thermal resistance of these radiators can be calculated by referring to the thermal resistance

of these radiators, and radiators composed of profiles with similar structural shapes (cross-sectional area and perimeter) can be used instead

will eventually be mapped to CPU operations through instruction sets. [1]

development history

in the computer, it is the core component responsible for reading instructions, decoding instructions and executing instructions. The central processing unit mainly consists of two parts, namely, the controller and the arithmetic unit, which also includes the cache memory

6 In the above calculation, some parameters are set, which may be different from the actual value, and the size of the substitute model is not exactly the same. Therefore, during mass production, a mold

simulation test should be conducted to confirm whether the radiator selection is appropriate. If necessary, some corrections (such as the length and size of the profile or changing the model of the profile) should be made before mass production

the core hardware unit for control deployment and general operation. CPU is
