Abstract
A heat dissipating device includes a heat sink, and an adjusting member. The heat sink includes a base, and a plurality of fins formed on a top surface of the base. The adjusting member includes a mounting portion mounted to a side surface facing an airflow-generating source of the base, a first air-blocking portion connected to an upper portion of the mounting part, and a second air-blocking portion connected to a lower portion of the mounting part. Positions of the first air-blocking portion and the second air-blocking portion relative to the base are adjustable for adjusting distribution of an airflow on top and bottom sides of the base when the airflow flows through the heat dissipating device.
Claims7
A heat dissipating device comprising:
- a heat sink comprising a base, and a plurality of fins formed on a top surface of the base, a passage being formed between the fins and having an inlet for entering of an airflow;
- and
- an adjusting member comprising a mounting portion mounted to a side surface of the base near the inlet, a first air-blocking portion connected to an upper portion of the mounting portion, and a second air-blocking portion connected to a lower portion of the mounting portion, wherein the first air-blocking portion and the second air-blocking portion are capable of being rotated relative to the mounting portion, a position of the first air-blocking portion and a position of the second air-blocking portion relative to the base are adjustable for adjusting distribution of the airflow on top and bottom sides of the base;
- wherein each of the first air-blocking portion and the second air-blocking portion is connected with the mounting portion with a torsion spring.
A heat dissipating device comprising:
- a heat sink comprising a base, and a plurality of fins formed on a top surface of the base;
- and
- an adjusting member comprising a mounting portion mounted to a side surface of the base, and an air-blocking portion rotatably mounted to the mounting portion, wherein the adjusting member is capable of controlling an airflow that enters into the fins by adjusting a position of the air-blocking portion relative to the base;
- wherein the air-blocking portion is connected with the mounting portion with a torsion spring.
A heat dissipating device assembly comprising:
- a circuit board with an electronic component mounted thereon;
- a heat sink comprising a base contacting the electronic component, and a plurality of fins extending from the base away from the electronic component;
- a first passage being formed between the fins;
- a second passage being formed between the base and the circuit board;
- and
- an adjusting member mounted to one lateral side of the base, the adjusting member comprising a mounting portion, and an air-blocking portion, wherein
- the air-blocking portion is capable of being rotated relative to the mounting portion, the adjusting member is capable of selectively entering and blocking one portion of one of the first passage and the second passage for adjusting distribution of an airflow on the first and second passages;
- wherein the air-blocking portion and the mounting portion are connected together with a torsion spring.
