Data Center Liquid Cooling Pump Solutions for High-Density Computing Applications

As artificial intelligence (AI), cloud computing, and high-performance computing (HPC) continue to evolve, data centers are facing unprecedented thermal challenges. Increasing rack power densities and growing energy consumption are accelerating the adoption of liquid cooling technologies.

At the heart of every liquid cooling system is the liquid cooling pump, which ensures stable coolant circulation and efficient heat transfer. Whether for cold plate cooling or immersion cooling, selecting the right pump directly impacts cooling efficiency, system reliability, and operational costs.

TOPSFLO provides a wide range of data center liquid cooling pump solutions designed to support next-generation computing infrastructure.

Why Data Centers Are Transitioning to Liquid Cooling

Traditional air cooling methods struggle to meet the thermal requirements of modern AI servers and high-density computing environments.

Rising Data Center Energy Consumption

According to the International Energy Agency (IEA), data centers account for approximately 1–1.5% of global electricity consumption, and cooling systems can represent up to 40% of total facility energy usage.

Improving cooling efficiency has therefore become a key strategy for reducing operating costs and improving sustainability.

AI Is Driving Higher Rack Power Density

Research from Dell’Oro Group indicates that traditional enterprise racks typically operated at 5–10 kW per rack, while AI deployments increasingly require 30–50 kW per rack. Some advanced AI clusters have already exceeded 100 kW per rack.

At these heat densities, liquid cooling becomes not only advantageous but necessary.

Liquid Cooling Delivers Better Energy Efficiency

According to ASHRAE Thermal Guidelines, liquid cooling technologies offer significantly higher heat transfer efficiency than air cooling and can reduce cooling-related energy consumption by 30–40%, depending on system design.

What Is a Data Center Liquid Cooling Pump?

A data center liquid cooling pump is a high-performance circulation pump designed to move coolant throughout liquid cooling loops.

Its primary functions include:

• Maintaining stable coolant circulation

• Transferring heat away from heat-generating components

• Improving cooling efficiency

• Supporting continuous 24/7 operation

• Enhancing overall system reliability

In liquid cooling systems, the pump functions as the “heart” of the cooling loop.

Data Center Liquid Cooling Pump Solutions with Different Functions

Modern data centers typically adopt two major liquid cooling architectures: cold plate liquid cooling and immersion liquid cooling.

Cold Plate Liquid Cooling Pump Solution

Cold plate liquid cooling removes heat indirectly through highly conductive metal cold plates.

Cold plates are enclosed cavities made from materials such as copper or aluminum and are installed directly on high-heat components including CPUs and GPUs.

Heat generated by these components is transferred to the coolant flowing through the cold plate, and the coolant then transports the heat to the rear-end heat exchanger for dissipation.

Main Components of a Cold Plate Cooling System

• Liquid cold plates

• Liquid cooling pumps

• Cooling pipelines

• Connectors and fittings

• Heat exchangers

• CDU (Cooling Distribution Unit)

Advantages of Cold Plate Cooling

• High cooling efficiency

• Easy integration into existing server architectures

• Lower coolant consumption

• Excellent compatibility with AI and GPU servers

• Reduced data center PUE

Immersion Liquid Cooling Pump Solutions

Immersion liquid cooling dissipates heat by directly submerging electronic components into dielectric cooling fluids.

Unlike cold plate cooling, immersion systems allow heat-generating components to exchange heat directly with the coolant.

The key equipment involved includes:

• Outdoor cooling sources

• Cooling subsystems

• Liquid cooling pumps

• Liquid cooling pipelines

• Immersion tanks or cooling cabinets

• Heat exchangers

Types of Immersion Liquid Cooling

Single-Phase Immersion Cooling

The coolant remains in liquid form throughout the cooling cycle.

Heat is transferred by circulating the fluid through heat exchangers.

Characteristics:

• Simpler system architecture

• Lower coolant cost

• Easier maintenance

•  Requires higher-flow pumps to promote circulation

Two-Phase (Phase-Change) Immersion Cooling

The coolant boils upon absorbing heat and condenses back into liquid after heat rejection.

Characteristics:

• Exceptional heat transfer capability

• Extremely high cooling efficiency

• Lower pump circulation requirements

• Higher system complexity

Advantages of Immersion Cooling

Supports ultra-high rack densities

Eliminates airflow limitations

Reduces cooling infrastructure footprint

Improves energy efficiency

Enables future AI computing expansion
