Claims
- 1. A cooling unit for electronic equipment, comprising a first box containing an electronic circuit board, a plurality of semiconductor devices and a keyboard, a second box made of metal material and containing a flat type display unit arranged to face the keyboard in a position in which the first and second boxes face each other to define a closed position with the second box having a wall constituting a lid, said second box having fins with one end contacting the wall and the other ends being free non-contacting ends each extending inwardly toward the display unit, a heat receiving section provided on at least one of said semiconductor devices, a heat dissipation section integrally connected to said wall of said second box so as to be thermally connected to said second box, and at least one thermal transport conduit connecting said heat receiving section and said heat dissipation section to each other and transporting heat therebetween such that the said wall of the second box constitutes a heat dissipation body.
- 2. A cooling unit for electronic equipment, comprising a first box containing an electronic circuit board, a plurality of semiconductor devices and a keyboard, a second box made of metal and containing a flat-type display unit arranged to face the keyboard in a position in which the first and second boxes face each other to define a closed position with the second box having a wall constituting a lid, said second box having fins with one end contacting the wall and the other ends being free non-contacting ends each extending inwardly toward the display unit, a heat receiving section provided on at least one of said semiconductor devices, a heat dissipation section integrally connected to said wall so as to be thermally connected to said second box, and at least one thermal transport conduit connecting said heat receiving section and said heat dissipation section to each other and transporting heat therebetween.
- 3. A cooling unit according to claim 2, wherein said heat receiving section and said heat dissipation section are provided therein with liquid passages, and said thermal transport means comprises liquid circulation flexible tubes configured to circulate a liquid between said heat receiving section and said heat dissipation section.
- 4. A cooling unit according to claim 3, wherein said liquid passages in said heat dissipation section are integrally formed in walls of said second box.
- 5. A cooling unit according to claim 3, wherein said liquid circulation flexible tubes are housed in said heat dissipation section.
- 6. A cooling unit according to claim 2, wherein heat dissipation fins are integral with said second box on a reverse side of said display unit opposite a side thereof facing said first box.
- 7. A cooling unit according to claim 2, wherein heat pipes are connected at one end thereof to said heat receiving section and fitted in U-shaped grooves formed integrally in and along walls of said first box.
