Two stage radiation thermoelectric cooling apparatus

A thermoelectric cooling apparatus for cooling an electronic device comprising:

• a front heat absorbing block comprising a bottom surface and two side surfaces, said bottom surface contacting said electronic device;
• a front heat conductive device having a first portion and a second portion, said first portion being connected with said front heat absorbing block, said second portion extending from an end of said first portion to a remote end away from said front heat absorbing block;
• a front radiator, connected with said second portion of said front heat conductive device;
• two thermoelectric coolers, each of said two thermoelectric coolers having a cold side and a hot side, said cold side being the opposite side of said hot side, each of said two thermoelectric coolers contacting one of said two side surfaces of said front heat absorbing block with said cold side for transmitting heat collected from said front heat absorbing block from said cold side to said hot side;
• and
• two back radiating modules contacting said hot sides of said two thermoelectric coolers respectively for radiating heat collected therefrom.
