Description
Technical field
The present invention relates to cooling systems, more particularly, to a kind of liquid cooling system of server.
Background technique
Now, the requirement with the rise and internet computer industry of the NPD projects such as artificial intelligence to graphics process
Also come higher, the demand to video card is also higher and higher.Video card, as the big customer of computer fever, the calorific value of monolithic is higher than
200W, this highdensity calorific value can not be ignored.Moreover, the performance of video card is in this growth also at double in several years, and work
Environment temperature is high, has all promoted the generation of video card " high fever " situation.And how GPU so solves firmly for the key in video card
Part chip heating problem, becomes the topic all paid close attention to for everybody.The radiating mode of currently used video card be it is active heat dissipation and
Passive heat radiation.Passive heat radiation is to install cooling fin in GPU surface, does not need radiator fan.Active heat dissipation uses
GPU surface installs radiator fan while installing cooling fin.
For passive heat radiation since its heat-sinking capability is poor, it is only used for the lower video card of working frequency, and actively
It is special since working environment causes out temperature unstable although formula heat dissipation can be used for the higher video card of working frequency
Summer not higher for environment temperature, heat-sinking capability are obviously limited by environment temperature.
Summary of the invention
For problem present in the relevant technologies, the purpose of the present invention is to provide a kind of liquid cooling system of server, with
At least realize the radiating efficiency for promoting server.
To achieve the above object, the present invention provides a kind of liquid cooling systems of server, comprising: cooling device accommodates
