Description

Server sealing method

This disclosure is about a server sealing method.

Two-phase immersion cooling systems are used to cool and preserve electronic systems (for example, servers). Through the phase change conversion of the dielectric liquid in the cooling system between the gaseous state and the liquid state, the heat dissipation efficiency of the electronic system contained therein is improved. And this kind of cooling system can also prevent the electronic system from being contacted by air, dust, etc. to cause malfunctions.

In order to reduce the leakage of dielectric liquid vapor in the cooling system, the housing of the cooling system needs to be airtight. However, the electronic system needs to be able to pass through the casing of the cooling system in order to be electrically connected to the outside world and transmit data. The general sealing method cannot maintain the airtightness of the cooling system shell at the same time when the electrical connection is made.
