High-Frequency Jet Impingement Liquid Cooling Plate (also commonly referred to as Jet Impingement Cold Plate) is a special liquid cooling solution for ultra-high heat flux and ultra-fast temperature uniformity. Its core mechanism is to achieve extreme heat dissipation by directly impinging the inner wall of the heating surface with high-frequency, high-speed, and high-pressure micro-jets.
I. Core Principle (Essential Difference from Traditional Flow Channels)
Traditional Liquid Cooling Plate:
Coolant flows in parallel within enclosed channels for heat exchange, featuring thick thermal boundary layer, high thermal resistance, and prone to hot spots at distant positions.
High-Frequency Jet Impingement Type:
Coolant passes through a dense array of micro-nozzles (diameter 0.1–1 mm)
Impinges vertically at high speed onto the inner wall of the cold plate (heating surface)
Instantly breaks the thermal boundary layer, increasing local heat transfer coefficient by 5–10 times
Fluid diffuses rapidly and drains laterally, achieving extremely uniform temperature across the whole area (temperature difference < ±1℃)
II. Typical Structure
Upper Chamber (Distribution Chamber): stabilizes pressure and distributes coolant evenly to nozzles
Nozzle Plate: core component with hundreds to thousands of precision micro-holes (high-frequency jet array)
Impingement Chamber (Heat Exchange Zone): jet impingement and intensive convective heat transfer
Ultra-high heat flux, hotspot-sensitive, high-precision temperature control
VII. Summary
High-Frequency Jet Impingement Liquid Cooling Plate represents the state-of-the-art liquid cooling technology in modern industry, designed specifically for extreme heat flux, ultimate temperature uniformity, and high-precision temperature control.
