Dummy load device for liquid cooling data machine room PUE detection
Technical Field
The utility model belongs to the technical field of the server test, concretely relates to dummy load device that is used for liquid cooling data computer lab PUE to detect.
Background
In order to ensure the delivery quality and performance of a data machine room, a plurality of newly-built data centers adopt a mode that a server dummy load simulates heating and power utilization of a real server before formal acceptance and use, so that the usability of the whole machine room system is tested, and the process is called comprehensive test of the machine room. When the comprehensive test is carried out, the adopted server dummy load is generally pure resistance type load. For an immersed liquid cooling data center, a server is cooled in a mode of completely immersing insulating cooling liquid, compared with the traditional data center, a machine room comprehensive test of the immersed liquid cooling data center needs not to install a fan, but needs to meet some performance requirements of immersed cooling of the insulating cooling liquid, for example, the heat flow density on the surface of a dummy load heating element cannot be too high, and the too high temperature can cause local overheating denaturation of the cooling liquid. Therefore, the air-cooling dummy load of the traditional data center is not suitable for the comprehensive test of the liquid cooling data machine room.
In view of this, patent document CN108680785A discloses a dummy load test apparatus including: the system comprises a box body, a heating body and a drainage component, wherein a liquid inlet is formed in the bottom area of the box body, a liquid outlet is formed in the top area of the box body, the heating body is positioned in the box body and used for simulating a server load in a working state under a liquid cooling environment, and the drainage component is positioned in the box body and used for guiding cooling liquid to flow from the liquid inlet to the liquid outlet in an S-shaped channel under the liquid cooling environment; the drainage component is a baffle plate, and only depends on the interaction between the self-flowing of the cooling liquid and the baffle plate, so that the overhigh temperature of the local area of the cooling liquid can be relieved, but the effect is poor.
