Driven by national dual-carbon policies and booming downstream markets, China’s cold chain industry is accelerating green and low-carbon upgrading. The “Cold Chain Star” initiative recognizes innovative enterprises leading technological and sustainable development across the sector.

The 37th China Refrigeration Exhibition opened grandly at Beijing Capital International Exhibition Center on April 8, 2026. As one of the world’s most authoritative expos covering refrigeration, air conditioning, heating and food freezing processing, it serves as a key platform for enterprises to display cutting-edge technologies and expand business cooperation.

The 5th China International HVACR & Cold Chain Industry Exhibition welcomed Xiaosong New Energy’s brand-new 2–15HP DC inverter EVI refrigeration and freezing units. The booth drew crowds of domestic and overseas professional buyers, who stayed to learn about the high-performance equipment amid active on-site communication.

Cold storage facilities maintain stable indoor temperature and humidity through mechanical refrigeration, widely used for freezing, refrigeration and constant-temperature storage of food, medicine and chemical products. Controlled atmosphere cold rooms further adjust oxygen and carbon dioxide content to preserve commodity quality. Cold storage types are classified by temperature range: high-temperature constant room (5–15℃), medium-temperature cold room (-5–5℃), low-temperature freezer (-25–-18℃), ultra-low temperature deep freezer (-60–-45℃) and quick-freezing room (-40–-35℃). A complete cold storage system consists of thermal insulation enclosure, refrigeration unit, throttle components, heat exchangers, piping and intelligent electric control system, together with supporting auxiliary equipment. Standard daily inspection and professional fault handling ensure long-term stable and reliable operation.

Driven by the rapid iteration of AI large model training, intelligent agent reasoning and supercomputing, global computing power demands continue to surge. The mismatch between fast-growing high-density computing loads and traditional thermal dissipation capacity has become a core bottleneck restricting data center development. To address industry pain points, professional container data center liquid cooling technologies have emerged as a key solution to support modular and edge computing upgrades.

This session focuses on the core supporting hardware of liquid cooling systems. It comprehensively analyzes the parameters, performance advantages and practical application values of key CDU liquid cooling equipment, including liquid-to-liquid CDU and air-to-liquid CDU, helping the industry fully understand standardized liquid cooling supporting solutions.

Modern high-load data centers face severe heat dissipation challenges due to rising cabinet power density and intensive computing workloads. The rear door liquid cooling solution adopts a collaborative cooling architecture with multiple liquid cooling back doors and chillers to form a circulating heat dissipation loop. By dispersing heat efficiently across the entire cabinet array, the system significantly improves cooling capacity while introducing redundant design to guarantee long-term operational stability and reliability. As a mature and reliable data center liquid cooling solution, this architecture supports flexible capacity expansion and convenient maintenance, ensuring continuous and stable server operation for large-scale computing facilities.

With the explosive growth of AI computing power, high-density heat dissipation has become a core challenge for modern data center operation. Cold plate liquid cooling has emerged as the most reliable and mainstream solution, featuring a complete dual-circuit framework composed of primary and secondary cooling loops. The systematic cyclic heat dissipation structure ensures stable and efficient heat removal, forming a mature and complete data center liquid cooling system that supports long-term high-load operation of computing equipment.

The secondary cooling loop takes surplus cooling capacity from the primary circuit to dissipate heat for core heat-generating components inside racks, including CPUs, GPUs, memory modules, hard drives and power supplies. Its main components cover CDU, site distribution pipelines and liquid cooling cabinets equipped with cold plates, quick disconnect fittings and manifolds, forming the core operating framework of a standard liquid cooling data center. This article systematically introduces all core liquid cooling parts of the secondary loop.

With the rapid growth of AI computing power, traditional air cooling can no longer support high-density server operation. As cabinet power density rises from 3-5kW to 8kW, 10kW or higher, legacy data centers widely suffer from full-speed fan operation, persistent high temperature, high PUE, energy compliance failures and frequent GPU server thermal throttling. In this context, air-to-liquid cooling retrofit has evolved from a marketing concept into a necessary upgrade for legacy room renovation and computing expansion, forming a reliable data center liquid cooling system for high-load scenarios.
