RELATED APPLICATIONS [0001] The present application is based on, and claims priority from, Taiwan Application Serial Number 94212496, filed Jul. 22, 2005, the disclosure of which is hereby incorporated by reference herein in its entirety. BACKGROUND [0002] 1. Field of Invention [0003] The present invention relates to a power supply. More particularly, the present invention relates to a power supply with a cooling function. [0004] 2. Description of Related Art [0005] Power sources of electronic apparatuses are generally transmitted from a power plant to a socket to which a power supply is connected. The power supply rectifies, transforms and filters alternating current and then provides it to apparatuses. Especially in a computer system, a power supply simultaneously provides several apparatuses with power for operation. A power supply is typically disposed near a central processing unit (CPU) in a computer in which the CPU operates independently and has no cooperation with the power supply. [0006] The central processing unit is generally equipped with a heat dissipation apparatus such as a CPU fan for preventing devices in the computer from failure due to a high temperature caused by heat generated during operation of the CPU. The CPU fan draws air from within the computer system to cool the CPU. The cooling effectiveness depends on the temperature of the air; the lower the temperature, the better the cooling. Thus, the internal air circulated by a CPU fan, which is heated by the devices operating in the computer system and is generally much warmer than the external room temperature air, has limited effectiveness in cooling a CPU. SUMMARY [0007] It is therefore an objective of the present invention to provide a power supply with a cooling function to supply power and cooling simultaneously. [0008] It is another objective of the present invention to provide a power supply with a cooling function to enhance a cooling efficiency for a CPU in a computer system. [0009] In accordance with the foregoing and other objectives of the present invention, a power supply with a cooling function is provided. The power supply with a cooling function includes a power supply case, a thermoelectric cooling module and a cold side heat dissipation member. The thermoelectric cooling module disposed at an installation surface opening of the power supply case has a cold side facing the outside of the power supply case, and a hot side facing the inside of the power supply case. The cold side heat dissipation member coupled with the cold side extends out of the power supply case for heat exchanging with external air outside the power supply case to lower the external air temperature. [0010] According to a preferred embodiment of the present invention, the power supply further includes a heat containment chamber having a first passage opening and a second passage opening. The power supply case further includes an outward opening coupled to the first passage opening and an inward opening coupled to the second passage opening. Also, a fan is installed between the first passage opening and the outward opening to direct heat gathered around the hot side to the outside of the case. [0011] The power supply further integrates a temperature control module for monitoring a temperature data to adjust a fan power source so that a fan speed can be controlled appropriately, and a humidity control module for monitoring a humidity data to adjust a thermoelectric cooling module power source so that an output power of the thermoelectric cooling module can be controlled appropriately. [0012] In conclusion, the power supply of the invention provides an extra function of lowering the temperature inside a system during operation by integrating a thermoelectric cooling module, especially for most present computer systems in which the installation location of the power supply is standardized. The present invention takes advantage of the standardized arrangement of the power supply to allow a CPU fan to draw heat exchanged air of lower temperature so that cooling efficiency for the CPU is raised. [0013] It is to be understood that both the foregoing general description and the following detailed description are by examples and are intended to provide further explanation of the invention as claimed.
