Problems solved by technology

[0011] In situations where the laptop happens to be carried alone, the cooling capacity of the microprocessor may not be sufficient
Therefore, especially when the microprocessor is tasked with complex calculations and processing, there is a danger that the temperature of the microprocessor will exceed the operating limit
If the temperature of the microprocessor becomes too high, the processing speed may become too slow, or it may become inoperable due to thermal overload
Therefore, it becomes impossible to fully utilize the full performance characteristics of the microprocessor

Embodiment Construction

[0040] An embodiment of the present invention will now be described with reference to the drawings of a portable computer.

[0041] Such as figure 1 As shown, the electronic system has a portable computer 1 as an electronic device, a cooling device 2 for cooling the portable computer 1 , and an expansion device 3 for expanding the functionality of the portable computer 1 .

[0042] Such as figure 2 As shown, the portable computer 1 is composed of a computer main body 5 and a display device 6 supported by the main body 5 . The main body 5 has a casing 7 . Shell 7 ( figure 1 Shown) is a flat box shape with a bottom wall 7a, a top wall 7b, a front wall 7c, left and right side walls 7d and a rear wall 7e. The top wall 7 b of the housing 7 has a palm rest 8 and a keyboard attachment part 9 . The palm rest 8 expands along the width direction of the housing 7 and occupies the front half of the housing 7 . The keyboard attachment part 9 is located behind the palm rest 8 and the...

Abstract

A cooling device (2) having a cooling module (70) with an electrically driven cooling device (72). This cooling module (70) is suitable for combining with a portable electronic device (1) having a heat-generating component (23) and a first connector (36) for power supply. A second connector (83) is provided for electrical connection with this cooling device (72). The second connector (83) is connected to the first connector (36) for supplying the power received from the first connector (36) to the cooling device (72) when it is combined with the portable electronic device (1).

Description

technical field [0001] The present invention relates to an electronic system having an electronic device, such as a portable computer, and a cooling device used in conjunction with the electronic device. Background technique [0002] The power consumption of portable electronic devices, such as notebook computers, continues to increase due to the higher processing speed and versatility of microprocessors, and the fact that the heat of microprocessors tends to scale up rapidly. Therefore, heat radiation from the microprocessor must be improved in order to ensure stable operation of the portable computer. [0003] As a countermeasure against this, common computers are provided with heat sinks thermally connected to the microprocessor, and here are electric fans which supply cooling air to the heat sink to cool down the hot microprocessor. [0004] According to this common cooling method, when the cooling air from the electric fan becomes the cooling medium that absorbs heat b...
