Immersed liquid cooling server and immersed liquid cooling method for server

Abstract

The invention relates to an immersed liquid cooling server and an immersed liquid cooling method for the server. The immersed liquid cooling server comprises a refrigerant groove, a heating element, a cooling element and a blower or a fan, wherein the refrigerant groove is used for accommodating refrigerants, the heating element is arranged in the refrigerant groove and is soaked by the refrigerants, the cooling element is positioned above the liquid level of the refrigerants, the blower or the fan is arranged above the cooling element, and the direction of airflow blown by the blower or the fan faces the cooling element. The immersed liquid cooling server has the forced condensing heat exchange effect. The immersed liquid cooling method for the server comprises the following steps that the refrigerants absorb heat of the heating element soaked into the refrigerants to form refrigerant steam through evaporation, and the refrigerants upwards flow; the cooling element carries out heat exchange with the upward flowing refrigerant steam, the refrigerant steam is condensed into refrigerant liquid drips, and the refrigerant liquid drips drip back into the refrigerant groove due to gravity effect; the air is downwards blown towards the cooling element through the blower or the fan. The method has the advantage that the condensed heat exchange of an immersed liquid cooling system is enhanced.

Description

technical field [0001] The invention relates to an immersion liquid cooling server and an immersion liquid cooling method for the server. Background technique [0002] Most of the computers currently in use rely on cold air to cool down the machine, but in data centers, air cooling alone is not enough to meet the heat dissipation requirements of high heat flux density servers. Water cooling or liquid cooling has two advantages: it can direct the coolant to the heat source instead of indirect cooling like air cooling; compared with air cooling, the heat transfer efficiency per unit volume is as high as 3500 times. Water-cooled radiators appeared in the market around 2008. Servers such as Hewlett-Packard and IBM and other companies focusing on data center technology have successively launched water-cooled heat dissipation products. [0003] From the thermal principle, evaporative cooling uses the latent heat of vaporization when the refrigerant boils to remove heat. Since th...

Problems solved by technology

However, because the cooling capacity of each part of the cooling element is different, and as the heat emitted by the heating element increases, the cooling capacity of the cooling element is not enough to completely condense all the rising refrigerant vapor, and the refrigerant vapor passes through the cooling element. upward flow, which in turn causes energy to be lost in the server

In addition, the cooling capacity of the cooling element is insufficient, resulting in the failure to cool the refrigerant vapor in time, causing the temperature of the refrigerant to rise, and the pressure of the entire refrigerant tank also rises accordingly, unable to complete the refrigeration requirements.
