Problems solved by technology

This patent uses the second circulation loop to take away the heat of the first circulation loop, but the radiator of the first circulation loop conducts heat to the air inside the entire server cabinet, and does not directly conduct heat to the server heating element chip, which leads to heat dissipation in the patent. The efficiency is low and the effect is poor. In addition, the first circulation loop is equipped with the first water pump. The first water pump generates more heat when it is running. It is necessary to set up a special heat exchanger to transfer the heat accumulated by the first water pump. This will undoubtedly burden the system. Thereby further reducing the heat dissipation efficiency of the system

Abstract

The invention discloses a server cabinet heat dissipation system combining a door-type cold water heat exchange device and a liquid cooling device. The cold server is equipped with a liquid cooling device for direct liquid cooling and heat dissipation for the liquid cooling server, and a door-type cold water heat exchange device for auxiliary heat dissipation. The invention has high density refrigeration, high heat exchange efficiency, low energy consumption, can solve local hot spots, small footprint, high reliability, low noise and long service life.

Description

technical field [0001] The invention relates to a cooling system for a server cabinet, in particular to a cooling system for a server cabinet combining the door-type cold water heat exchange device and a liquid cooling device. Background technique [0002] With the continuous increase of high-density cabinets in the IDC Internet data center computer room, the integration of equipment is getting higher and higher, and the processing capacity is gradually increasing, but the power consumption of the equipment is also increasing, resulting in more heat generated by the equipment in the cabinet. According to statistics, at present, the cabinet servers in large-scale IDC computer rooms in China generate a lot of heat, and basically run 8760h throughout the year. It accounts for about 40% to 50% of the overall energy consumption of the data center. [0003] Traditional data room air supply methods include floor air duct air supply, hot and cold aisle isolation air supply, and who...
