Description

  The present invention relates to an information processing apparatus including a heat dissipation fan that cools electronic components.

Conventionally, a TV device is mounted on a personal computer (PC), and when a TV program is viewed for a long time, heat is generated in the PC. Electronic components such as TV tuners and CPUs that receive TV programs cause failure due to heat generation.
Therefore, the heat generated by the TV tuner and the heat generated by the CPU are released outside the PC by one large heat radiating fan.

  The TV tuner is cooled by placing the TV tuner in the middle of the flow path from the intake port of the PC to the heat dissipation fan and operating the heat dissipation fan. Although a temperature sensor is placed on the TV tuner together with the CPU to perform cooling according to the temperature, it is necessary to secure an air volume with a large heat radiating fan for appropriate cooling because of such a cooling method.

  In the case of a PC that does not include a TV tuner, the cooling structure itself is the same as a PC that includes a TV tuner. Since the PC not equipped with the TV tuner is not cooled according to the temperature of the TV tuner, the number of rotations of the heat dissipation fan is smaller than that of the PC equipped with the TV tuner.

Patent Document 1 discloses a heat dissipation system in which an intake port and an exhaust port are formed in a housing and a CPU and a video chip are mounted.
CPU heat is carried to the heat sink via the heat pipe, and video chip heat is carried to the heat sink via the heat pipe. The temperature sensor monitors the temperature of the CPU, and the temperature sensor monitors the temperature of the video chip.

  When the heat dissipating fan is operated, outside air is sucked from the air intake port, air in the housing is exhausted from the exhaust port via the heat sink, and heat is radiated from the CPU and the video chip. The revolving door is driven by a stepping motor and adjusts the ratio of the amount of air that the heat dissipation fan supplies to the heat sink.

  However, in the prior art, when cooling a component that is mounted or not mounted, such as a TV tuner, if one large heat dissipation fan is installed in the PC, the PC becomes larger and the thickness of the main body increases. There was a problem that.

  In the technique disclosed in Patent Document 1, electronic components such as HDDs are cooled in addition to the CPU by a large heat radiating fan, but the problem of downsizing and thinning of the PC cannot be solved.
