Abstract

A cooling system for a small computer has one or more heat transfer devices (12, 30) in intimate, heat-exchanging contact with heat-producing computer components. Liquid coolant is circulated through conduits from a reservoir (48) to the devices (12, 30). A radiator (42) is mounted on the outside of the computer housing (7) and is in heat-exchanging contact with the reservoir (48). The contact is preferably provided by a Peltier effect cooling module (46). A pump (P) is positioned in the reservoir casing (50) to pump the coolant. A brushless electric motor is mounted on the casing (50) to power the pump (P). The reservoir (48) has an upstream portion (58) and a downstream portion (60). Coolant is directed through the upstream portion (58) past heat-gathering fins (64) and into the downstream portion (60).
