Cooling unit and electronic device
View Patent ↗According to one embodiment, a cooling unit includes a heat dissipating mechanism, a fan, and a movable cover. The heat dissipating mechanism is housed in a housing of an electronic device. The fan is housed in the housing, and generates an air flow that collides against the heat dissipating mechanism. The movable cover includes a sheet and a knob. The sheet serves as an openable and closable cover to cover an opening on a chamber formed between the fan and the heat dissipating mechanism from the outside. The knob is located on the sheet and protrudes outward.
1. An electronic device comprising:
a cooling unit comprising:
a casing having a casing opening;
a heat dissipating mechanism housed in the casing;
a fan housed in the casing, the fan configured to generate an air flow that collides against the heat dissipating mechanism; and
a chamber located in the casing and the chamber located between the fan and the heat dissipating mechanism,
wherein the casing opening is directly above the chamber between the fan and the heat dissipating mechanism; and
a movable cover comprising:
an elastic sheet configured as an openable and closable cover to cover the casing opening, the movable cover being on an outside of the casing; and
a knob located on the elastic sheet and protruding away from the casing, and
wherein one end of the elastic sheet is fixed to an outside of the casing, another end of the elastic sheet is configured to be bent in a direction away from the casing to uncover the casing opening to provide access to the chamber located between the fan and the heat dissipating mechanism.
2. The electronic device of claim 1 , wherein the knob is made of a different material from the elastic sheet.
3. The electronic device of claim 2 , wherein the different material is a flexible material.
4. The electronic device of claim 2 , wherein the different material is an elastic material.
5. The electronic device of claim 2 , wherein the heat dissipating mechanism comprises a heat pipe, and a plurality of fins layered along the heat pipe,
the casing comprising a casing wall, the casing wall having the casing opening, the casing opening extending along a direction in which the plurality of fins are layered,
wherein a length of the knob is arranged along the direction in which the plurality of fins are layered.
6. The electronic device of claim 5 , wherein a part of the knob is located above the casing opening when the casing opening is covered with the elastic sheet.
7. The electronic device of claim 5 , wherein the casing opening includes a plurality of casing openings arranged along the direction in which the plurality of fins are layered.
8. The electronic device of claim 5 , further comprising
a housing having a housing wall, the housing wall having a housing opening, the cooling unit housed in the housing;
a removable cover covering the housing opening, the removable cover being on an outside of the housing,
wherein the knob is elastically held through the housing opening between the casing wall and the removable cover.
