Abstract: A computer includes a motherboard (2), an enclosure (1), and a fan (153). The motherboard has a first heat generating device (21 ) mounted thereon. The enclosure has a substantially sealed first compartment (10), and an airflow chamber (30) in communication with an exterior of the enclosure. The first compartment receives the first heat generating device therein. The first compartment has a first heat exchanger (3) for conducting heat from an interior of the first compartment to the airflow chamber. The fan is arranged in the airflow chamber.

Abstract: A heat dissipating system comprises a computer enclosure (1), a motherboard (2), at least one dividing panel (271), at least one heat generating element, and at least one heat dissipating device. The computer enclosure has a bottom panel (11). The motherboard is mounted on and substantially parallel to the bottom panel. The at least one dividing panel is perpendicularly attached to the motherboard. The computer enclosure and the at least one dividing panel cooperatively form at least two heat dissipating chambers. The at least one heat generating element is disposed in each of the at least two chambers. The at least one heat dissipating device is disposed in each of the at least two heat dissipating chambers.

Abstract: A self-adjusting hot box includes a box (1) with a fan, a heater (50) placed in the box (1), a thermostat (30) and a power supply (20) applied to provide power to the fan (12), the thermostat (30) and the heater (50). The heater (50) includes a plurality of heat generating devices, and each of the heat generating devices includes a plurality of power resistors (60) in electrical parallel connection. The thermostat (30) includes a T type thermocouple (33) disposed in the box (1), a double-acting relay (37), a temperature controller (32) and a plurality of single-acting relays. The power supply (20) includes a transformer (21), a bridge clipper diode (23) and a capacitor (25).
