Electronic apparatus including a cooling unit for cooling a heat generating component

An electronic apparatus comprising:

• a housing containing a heat generating component;
• a display unit supported by said housing;
• a heat receiving portion accommodated in said housing and thermally connected to said heat generating component;
• a heat exchanging portion installed on said display unit;
• circulating means for circulating cooling medium between said heat receiving portion and said heat exchanging portion, said circulating means being disposed throughout said housing and said display unit and having a pipe line for introducing cooling medium heated by said heat receiving portion to said heat exchanging portion;
• and
• intermediate cooling means installed in said pipe line of said circulating means, said intermediate cooling means forcing the heated cooling medium flowing from said heat receiving portion to said heat exchanging portion to be cooled.

An electronic apparatus comprising:

• a first housing containing a heat generating component;
• a second housing, said second housing being journaled detachably on a rear end of said first housing through a hinge device having a hinge shaft extending in the width direction of said first housing and having a rear face which is directed backward of said first housing when said second housing is rotated to a posture in which it stands up from the rear end of said first housing;
• a heat receiving portion accommodated inside said first housing and thermally connected to said heat generating component;
• a heat exchanging portion installed on said second housing, said heat exchanging portion being capable of being taken out of said rear face;
• and
• circulating means for circulating the cooling medium between said heat receiving portion and said heat exchanging portion, said circulating means comprising a first pipe line for introducing cooling medium heated by said heat receiving portion to said heat exchanging portion and a second pipe line for introducing cooling medium cooled by heat exchange by means of said heat exchanging portion to said heat receiving portion, said first and second pipe lines being disposed throughout the inside of said first housing and the inside of said second housing via backward of said hinge shaft, said rear face of said second housing having at least an opening portion at a position corresponding to said first and second pipe lines, said opening portion being covered with a removable lid.

An electronic apparatus comprising:

• a housing accommodating a heat generating component and being capable of being opened upward;
• a display unit supported by said housing;
• a heat receiving portion accommodated in said housing and thermally connected to said heat generating component;
• a heat exchanging portion installed on said display unit;
• and
• circulating means for circulating cooling medium between said heat receiving portion and said heat exchanging portion, said circulating means comprising a first pipe line for introducing cooling medium heated by said heat receiving portion to said heat exchanging portion and a second pipe line for introducing cooling medium cooled by heat exchange by means of said heat exchanging portion to said heat receiving portion, said first and second pipe lines being disposed throughout the inside of said housing and the inside of said display unit and being divided to upstream portions and downstream portions inside said housing, said upstream portions and said downstream portions being connected detachably through a joint, said joint having closing means for closing said first and second pipe lines when said first and second pipe lines are divided to the upstream portions and the downstream portions.
