other side very hot partly because of heat pulled from the cpu itself and partly due to the low efficiency of the tec component which generates additional heat in operation the component actually pumps heat from the cold side to the hot side the thermoelectric component has a low efficiency and demands high power for operation which is the reason tec 39 s were generally not considered to be useful for cooling cpu 39 s and other heat producing components there are many models of thermoelectric coolers each with different characteristics and requiring a different power input for an advanced cpu a high power thermoelectric component is needed referring now to fig1 and 2 there are shown respective schematic and block diagram illustrations of a cooling system for a computer cpu constructed and operative in accordance with one embodiment of the present invention the cooling system of the present invention consists of three parts 1 a pci or isa card 10 one example of a suitable card 10 is shown schematically in detail in fig3 card 10 includes a low profile switch mode mains operated power supply 12 with a high frequency ferrite or planar transformer microprocessor control unit 14 battery charger 16 rechargeable batteries 18 a fan 20 a main power connector 22 located on metal bracket 24 and a connection 26 to a flexible air pipe a second pcb 28 is mounted on card 10 and serves as a connector to the pc extension slot not shown on the motherboard an enclosure temperature sensor 29 is provided seated on card 10 card 10 is preferably internally split into two sections as by a separator 19 in this case half of the card is used for the electronics and batteries and the other half is used for.
