A computing cooling system includes a chassis having chassis air inlet(s) and outlet(s). Heat dissipation device(s) thermally coupled to heat producing component(s) are located in the chassis adjacent the chassis air outlet(s). A first fan device located in the chassis adjacent the chassis air inlet(s) pulls first air from outside the chassis into the first fan device via the chassis air inlet(s), and pushes the first air though the heat dissipation device(s) and out of the chassis via the chassis air outlet(s). A second fan device located in the chassis adjacent the chassis air inlet(s) pulls second air from outside the chassis into the second fan device via the chassis air inlet(s), pushes a first portion of the second air past the heat dissipation device(s) and out of the chassis via the chassis air outlet(s), and pushes a second portion of the second air into the chassis.

A cooling system for cooling components in an information handling system contained in a portable chassis comprises a die plate for receiving heat from a component, a heat pipe for transferring heat from the die plate to a single heat exchanger, a fan for generating an airflow across the heat exchanger and a thermal battery. The heat pipe comprises at least one curvature and the thermal battery is coupled to the die plate and has a length and a width such that the thermal battery is in contact with the heat pipe from the die plate to a point past the at least one curvature. The thermal battery may be formed from a thermally conductive material, be a vapor chamber or otherwise facilitate heat transfer to a heat pipe from the die plate to a point past the curvature for improved cooling.

The disclosure relates to an electronic device with active cooling. In order to make a compact design of an electronic device possible and furthermore ensure a high level of ESD/EMC protection and a high level of IP protection, it is proposed according to the disclosure that a housing of the electronic device is connected to a main body of a fan. When the main body and housing are in a connected state, an opening to the interior of the housing is closed off. The main body is furthermore connected to a bushing on which the fan rotor is mounted for rotation. In the connected state, a chamber is furthermore formed which is separated from the interior of the housing and in which the fan rotor is arranged. Here, the chamber forms a housing for the fan rotor.
