Patented Technology

Efficient Low-Temperature Energy Conversion

NovoPower’s patented Low-Temperature HTE™ (heat-to-electricity) system can generate cost effective electricity at temperatures as low as 50°C, across a wide range of duty cycles. Competing technologies require higher temperatures and stable operating conditions. Our 50kW system uses an organic working fluid to drive a free-piston generator. Combined with our sophisticated Smart Control System, our technology has the most efficient performance of any heat-to-electricity technology available.

Solution

Harnessing Waste Heat For Data Center Power

Traditional data centres are air-cooled. They use large fans to draw the hot air away from the computers, and expel the waste heat to the atmosphere. For every 100 units of computing power, it takes another 40 units of power (or more) for cooling and other services, resulting in a Power Usage Effectiveness (PUE) of 1.4 (140%). In a liquid-cooled data centre (with either immersion or direct-to-chip cooling), the heat is carried away by a liquid. Liquid-cooled data centres are much more efficient, with a PUE as low as 1.03 (103%). But the waste heat is still wasted. NovoPower systems allow it to be converted back into power, replacing some of the electricity the data center would otherwise have had to buy.

How It Works

Capture

In immersion cooling, heat from the servers is absorbed by the nonconducting liquid in which they are immersed. In direct-to-chip cooling, the servers are in racks with tiny heat exchangers attached to the processors. This method ensures efficient heat absorption directly at the source.

Convert

The hot fluid from the servers is circulated through a heat exchanger, which uses the heat to vaporize an environmentally friendly working fluid. This pressurized vapor expands, pushing a piston through a cylinder (a “free-piston expander”), driving a generator to produce electricity.

Control

NovoPower’s sophisticated control system seamlessly adapts in real-time by varying the flows and parameters of the electrical system. This makes our Low-Temperature HTE™ (heat-to-electricity) system the only viable solution for liquid-cooled data centers. It ensures optimal performance and energy efficiency.
