Abstract
An electronic device includes a cabinet, a first heat generating member, a second heat generating member, a fan unit, a first heat pipe and a second heat pipe. The first and second heat pipes are each formed by sealing an operation fluid which shifts its phase between gas and liquid into a pipe-like main body. In the second position, the first end portion of the first heat pipe is located at a position lower than that of the second end portion and the one end portion of the second heat pipe is located at a position higher than that of the other end portion. The second heat pipe includes a conveying mechanism that conveys the operation fluid in liquid phase from the other end portion to the one end portion.
Claims8
An electronic device comprising:
- a cabinet;
- a first heat generating member and a second heat generating member housed inside the cabinet;
- a fan unit configured to cool down the first heat generating member and the second heat generating member;
- a first heat pipe comprising a first end portion thermally connected to the first heat generating member and a second end portion provided in a vicinity of the fan unit;
- a second heat pipe comprising one end portion thermally connected to the second heat generating member and an other end portion provided in a vicinity of the fan unit,
- a heat transfer fluid which changes its phase between gas and liquid,
- wherein:
- the first heat pipe comprises a pipe-like first main body and the heat transfer fluid contained in the first main body;
- the second heat pipe comprises a pipe-like second main body and the heat transfer fluid contained in the second main body;
- the first end portion of the first heat pipe is located at a position lower than that of the second end portion and the one end portion of the second heat pipe is located at a position higher than that of the other end portion;
- and
- the second heat pipe comprises a transport mechanism configured to convey the heat transfer fluid upward from the lower end portion to the higher end portion.
An electronic device comprising a display unit containing a display and a main body unit configured to support the display unit, the electronic device configured to shift its posture between a first state in which the display unit is configured to be open with respect to the main body unit and a second state in which the main body unit is configured to be covered with the display unit while the display unit is exposing the display to outside,
- wherein the main body unit comprises:
- a cabinet;
- a first heat generating member and a second heat generating member housed inside the cabinet;
- a fan unit configured to promote cooling-down of the first heat generating member and the second heat generating member;
- a first heat pipe comprising a first end portion thermally connected to the first heat generating member and a second end portion provided in a vicinity of the fan unit;
- a second heat pipe comprising one end portion thermally connected to the second heat generating member and an other end portion provided in a vicinity of the fan unit,
- a heat transfer fluid which changes its phase between gas and liquid,
- and further wherein:
- the first heat pipe comprises a pipe-like first main body and the heat transfer fluid contained in the first main body;
- the second heat pipe comprises a pipe-like second main body and the heat transfer fluid contained in the second main body;
- the first end portion of the first heat pipe is located at a position lower than that of the second end portion and the one end portion of the second heat pipe is located at a position higher than that of the other end portion;
- and
- the second heat pipe comprises a transport mechanism configured to convey the heat transfer fluid upward from the lower end portion to the higher end portion.
An electronic device comprising:
- a cabinet;
- a first heat generating member and a second heat generating member housed inside the cabinet;
- a fan unit configured to cool down the first heat generating member and the second heat generating member;
- a first heat pipe comprising a first end portion thermally connected to the first heat generating member, a second end portion provided in a vicinity of the fan unit, and a first conveying mechanism;
- a second heat pipe comprising one end portion thermally connected to the second heat generating member, an other end portion provided in a vicinity of the fan unit, and a second conveying mechanism different from the first conveying mechanism, wherein:
- the first end portion of the first heat pipe is located at a position lower than that of the second end portion, and the one end portion of the second heat pipe is located at a position higher than that of the other end portion.
