Description

Liquid cooling conduit

This case is about a conduit, especially a liquid-cooled conduit.

At present, liquid cooling systems have been widely used in data centers or communication equipment to actively dissipate heat for electronic devices in racks, such as servers, switches, or storage devices.

To achieve the effect of preventing liquid leakage and improving accuracy.

In order to achieve the aforementioned purpose, a broad implementation aspect of the present case is to provide a liquid cooling conduit, which is applied to a liquid cooling system and is configured to receive and transmit cooling liquid. The liquid cooling conduit includes a flow channel body and a plurality of fluid connectors. The flow channel body includes a base portion, a pipe wall portion and a fixing portion. The pipe wall part is connected between the base part and the fixed part, and a flow channel is formed between the base part, the pipe wall part and the fixed part, and the flow channel is framed for the circulation of the cooling liquid.
