Abstract

The invention discloses a heat radiation device, a manufacturing method of the heat radiation device and a server, and belongs to the technical field of hardware heat radiation. The heat radiation device comprises a heat radiation base plate, a heat radiation assembly and a plurality of heat radiation fins, wherein the heat radiation fins are arranged on the first side of the heat radiation base plate, and are used for radiating the heat on the heat radiation base plate; the first surface of the heat radiation assembly is fixedly arranged on the second side of the heat radiation base plate; agap is formed between the side surface of the heat radiation assembly and the heat radiation base plate; the second surface of the heat radiation assembly is used for being attached to a first devicerequiring the heat radiation so as to radiate the heat on the first device requiring the heat radiation; a region which is not provided with the heat radiation assembly on the second side of the heatradiation base plate is used for being attached to other heat radiation devices; and the heating power of the first device requiring the heat radiation is greater than the heating power of other devices requiring the heat radiation; and other devices requiring the heat radiation are devices except for the first device requiring the heat radiation. Therefore the heat radiation efficiency of the heat radiation device is improved.

Description

technical field [0001] The invention relates to the technical field of hardware heat dissipation, in particular to a heat dissipation device, a manufacturing method thereof, and a server. Background technique [0002] With the continuous improvement of chip performance in the server, the heat generated by the chip is increasing. At the same time, due to the high integration of the internal components of the server, the heat in the server is highly concentrated. Therefore, how to effectively dissipate heat from the server is an urgent need. solved problem. [0003] The chips in the server may include: processing chips, and other low-power consumption chips such as memory chips. The processing chips may include a central processing unit (Central Process Unit; CPU) and a graphics processing unit (Graphics Processing Unit; GPU). It may include a high bandwidth memory (High Bandwidth Memory; HBM) chip and the like. Generally, processing chips, memory chips and other low power c...
