Problems solved by technology

When this cooling device is in use, the airflow provided by the fan only flows out of the electronic device after passing through the radiator, and cannot effectively dissipate heat for other electronic components in the electronic device.
This will cause some electronic components

Abstract

A radiating device is used for radiating of electronic components and comprises a hot pipe, an air guiding plate, a radiating fin group and a centrifugal fan. The hot pipe comprises a steaming section which is in thermal contact with the electronic components and a condensation section extending from the steaming section. The centrifugal fan is provided with an air outlet, and the radiating fin group is arranged at the air outlet. The condensation section extends to the air outlet and is in thermal connection with the radiating fin group. The air guiding plate extends from the air outlet to one side of the centrifugal fan, and the air guiding plate is provided with a first end close to the air outlet and a second end away from the air outlet. Two sides of the air guiding plate form an air inlet flow channel and an air outlet flow channel respectively. Air flow produced by the centrifugal fan flows in from the air inlet flow channel on one side of the air guiding plate and flows out from the other side of the air guiding plate after passing around the second end of the air guiding plate. The invention further relates to an electronic device using the radiating device.

Description

technical field [0001] The invention relates to a cooling device, in particular to a cooling device capable of cooling multiple electronic components at the same time. The invention also relates to an electronic device using the cooling device. Background technique [0002] With the continuous development of the electronic information industry, the operating frequency and speed of electronic components in electronic devices are also increasing, resulting in more and more heat and higher temperatures generated by electronic components, seriously affecting the performance of electronic devices. In order to ensure the normal operation of electronic devices, the heat generated by these electronic components must be dissipated in a timely manner. For this reason, heat sinks are widely used in various electronic devices. [0003] A commonly used cooling device generally includes a radiator and a fan. The heat sink is formed by interlocking a plurality of heat sinks arranged in ...
