Description

Built-in automatic liquid supplementing unit of liquid cooling equipment Technical Field The utility model relates to the technical field of central liquid cooling systems, in particular to a built-in automatic liquid supplementing unit of liquid cooling equipment. Background The data center liquid cooling technology is gradually developed into a single-phase/two-phase liquid cooling system from early dependence on air cooling, the CDU is used as a core component to bear the functions of cooling liquid circulation and pressure regulation, and an external liquid supplementing tank or a manual liquid supplementing mode is adopted in the prior art. The prior art has the following defects: a. the liquid supplementing hysteresis is that external liquid supplementing depends on manual monitoring, and response delay causes system pressure to be too low, so that heat dissipation efficiency is influenced and even terminal equipment is damaged; b. The liquid compensation amount is controlled in a misalignment way, namely, the liquid compensation amount can not be accurately controlled by manual liquid compensation control, which can lead to CDU The pressure exceeds or falls below a required threshold, and it is difficult to maintain the optimal pressure balance state of the CDU system; c. the resource waste is that the high-pressure discharged cooling liquid is directly discharged and cannot be recycled; d. The pollution risk is that the open type liquid supplementing system is easy to introduce impurities and block the pipeline; e. the operation and maintenance are inefficient, personnel need to carry special tools to frequently carry out liquid level inspection and manual liquid supplementing, and the working intensity is high and time is consumed. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides the built-in automatic liquid supplementing unit of the liquid cooling equipment, and the built-in liquid supplementing unit realizes pressure self-adaptive liquid supplementing, liquid level grading protection, discharged liquid recycling and pollution filtering, so that the frequency and workload of manual intervention are greatly reduced, the idle running risk of a liquid supplementing pump is prevented by three-level liquid level, early warning can be carried out in advance, a full-automatic liquid supplementing mechanism is realized, and great convenience is brought to production and use. In order to solve the technical problems, the technical scheme adopted by the utility model is to provide an internal automatic liquid supplementing unit of liquid cooling equipment, which comprises an external container, an internal liquid supplementing unit connected with the external container and a liquid cooling unit connected with the internal liquid supplementing unit, wherein the internal liquid supplementing unit comprises a liquid supplementing container shell, a first one-way valve arranged on the liquid supplementing container shell, a first liquid level sensor, a second liquid level sensor, a third liquid level sensor, a first ball valve and a second ball valve which are sequentially arranged on the liquid supplementing container shell from top to bottom, the first ball valve is arranged at the bottom (but not limited to) of the liquid supplementing container shell, the second ball valve is arranged at the top (but not limited to) of the liquid supplementing container shell, the external container is communicated with the first one-way valve through a first pipeline, a filter and the first liquid supplementing pump are sequentially arranged on the first pipeline along the liquid supplementing flow direction, the second ball valve is communicated with a unit pump inlet pipe in the liquid cooling unit through a second pipeline, and the second liquid supplementing pump and the second one-way valve are arranged on the second pipeline, and the third ball valve is communicated with a pump outlet pipe in the liquid cooling unit through the third pipeline.
