Description

Technical Field

[0001] The invention belongs to the technical field of cooling electronic components, and in particular relates to a pump drive device. Background Art

[0002] With the development of electrical equipment packaging, wafer processing and lithography technology, the power density of electronic devices continues to increase, resulting in an increase in the heat flux density of the devices. Traditional air cooling methods cannot meet cooling needs or application scenario requirements. Liquid cooling systems will eventually replace air cooling systems due to their high cooling efficiency, low noise, high reliability, energy saving and consumption reduction.

[0003] In the power electronics industry, liquid cooling technology is used to cool heating elements including but not limited to 1) cabins, converters, generators, etc. in the fields of new energy wind power and photovoltaics; 2) inverters, power units, charging piles, etc. in the field of industrial variable frequency drives; 3) thyristor valves, insulated gate bipolar transistor (IGBT) valves, circuit breakers, reactive power compensators, etc. in the DC transmission and distribution industry. Liquid cooling technology was applied to the power electronics industry in 1878, and its current application tends to be more integrated and high-density design.

[0004] In the ICT industry, with the rapid iteration and development of ICT products, the heat dissipation problem of products such as CPU, GPU, baseband processing unit (BBU), dual in-line memory module (DIMM) has become increasingly prominent. The cooling technology of data centers is gradually advancing from room-level cooling to row-level cooling, rack-level cooling, and server-level cooling. Liquid cooling technology is gradually replacing air cooling technology.

[0005] In the rail transit industry, the cooling technology for component products such as inverters, rectifiers, and new energy battery packs has basically achieved the application of liquid cooling technology.

[0006] In the medical device industry, high-power precision medical devices such as medical imaging products have also had mature liquid cooling technology applications and have irreplaceable advantages and characteristics.

[0007] Therefore, in the ICT industry, power electronics industry, rail transit industry, and medical device industry, single-phase liquid cooling systems and phase change liquid cooling systems have become research and development hotspots.

[0008] 1) Single-phase liquid cooling

[0010] 2) Phase change liquid cooling

[0011] The cooling medium is driven into the liquid distributor by an immersion pump drive device, and evenly distributed to each heat-generating component through the liquid distributor. After absorbing the heat of the heat-generating component, the cooling medium partially undergoes phase change to form a gas-liquid two-phase flow. The two-phase flow cooling medium enters the condenser, and the heat carried by the cooling medium is dissipated to the environment through the condensation process of the condenser. The cooling medium is re-condensed into a liquid state and returns to the immersion pump drive device to form a closed cycle. Condensers include plate heat exchangers, air-cooled radiators, and other types.
