Description

Heat sink

The present invention relates to a heat sink, and more particularly to a heat sink including a fan module.

In a typical system, a fan is disposed in the outer casing of the system, and an air flow passage is disposed between the fan and the outer casing, so that the airflow can enter or leave the fan through the airflow passage, and heat exchange is performed to achieve the heat dissipation effect.

In the case where the internal space of the system casing is limited, in order to retain a certain airflow passage, the size space that the fan can be set is limited. In this way, when the system needs to increase the size of the fan to improve the heat dissipation efficiency, the airflow passage between the fan and the outer casing is reduced, and the resistance of the airflow is increased, resulting in a decrease in the overall heat dissipation capability of the system.

The present invention provides a heat sink comprising a housing, a connector and a fan module. The housing includes an opposing first cover and a second cover. The second cover has an opening. The adapter is coupled to one of the first cover and the second cover within the housing. The fan module is movably coupled to the engagement member and configured to move between the first position and the second position relative to the housing based on the engagement member. When the fan module moves to The first position is located within the housing.

In summary, in the heat dissipating device of the present invention, the fan module can be moved between the first position and the second position relative to the housing based on the engaging member in the housing, thereby changing the relationship between the fan module and the housing. The purpose of the airflow channel size. When moving to the first position, the fan module is located within the housing. In practical applications, the heat sink of the present invention can make the fan module not open when moving to the first position, and then turn on when moving to the second position. Therefore, when the fan module is in the first position, the heat dissipating device of the present case does not need to leave any airflow passage to the fan module, so that the fan module can be completely filled with the airflow channel by using a larger fan module; and when the fan module When in the second position, the larger size fan module is not limited by the housing, thereby maintaining its heat dissipation capability.

In an embodiment, the setting is It is disposed between the extending portion 131a and the first stopper 140, and is disposed to push the extending portion 131a to move the fan module 130 toward the second position. Thereby, when the outer cover 170 leaves the second cover 112, the pushing member 150 immediately pushes the fan module 130 to the second position.

In the present embodiment, the pushing member 150 is a tower spring. Thereby, when the fan module 130 is moved to the first position (as shown in FIG. 1A), the pushing member 150 can be compressed flat between the extending portion 131a and the first stopping member 140, thereby occupying The small space further reduces the influence of the movement of the fan module 130 relative to the housing 110.
