Server Thermal Solution

It’s the era of big data, at least 2.5 quintillion bytes of data are produced every day in the data centres. And the server is there to help process the data. In 2019, 3M launched immersion cooling for data centres where electronic components are directly immersed in dielectric liquid in a sealed but readily accessible enclosure where heat from electronic components is transferred to the fluid.

Before we dig in deeper, what is a server? In computing, the server can be hardware or software that provides services such as sharing data or resources to clients (e.g computer, mobile phone) provides services like sharing data or resources. Typical serves are database servers, file servers, mail servers, print servers, web servers, game servers, and application servers. Said that sever is entangled and closely connected to our everyday life.

Server Dimension

When it comes to the server, we often hear 1U, 2U, etc. In fact, the server dimension is standardized in width 48.26cm and height 4.445cm. U refers to the height of the server, 1U=4.445cm or 1.75inch and 2U= 8.89cm (4.445cmx2) or 3.5inch. 42U is the standard rack, at 19 inches.

Internal Structure

Here is an example of a 1U server layout. The fans are placed in the centre of the server to facilitate the front to back airflow for rapid heat dissipation.

Thermal Solutions

Now let’s go through these different types of thermal products, which are applied in the server equipment in our daily life. Due to various scales of data management, a suitable cooling device plays an important role here. Multiple thermal solutions are deployed in the server, we classify them as following.

BTU

A British Thermal Unit (BTU) is used to measure thermal or heat energy for the server. BTU/hr is equivalent to 3.4Watts, and 12,000 BTU/hr is considered a Ton.** If a server has a heat dissipation (output) of 400 Watts the thermal or heat energy generated is 1360 BTU/hr. Bear in mind, other heat sources like lighting, monitors and other equipment must be concluded when designing server thermal solutions.

** A 1-ton window AC is an ideal choice for a room of 120-150sqft (11-14 sqm2)

DC Fan

Fan is indispensable for the server and is often in ultra-high fan speed, which may vary subject to server design. Zaward’s offers various fan series for heat dissipation.

Cooler

With a strong technical background, Zaward manufactures tailor-featured passive and active coolers for AMD, Intel mainstream platforms and others. We customize designs for all kinds of size units (1U, 1.5U, up to 4U) for servers as well.

Liquid cooling

To fulfil a higher level of data storage and transaction, the liquid cooling system is one of the critical factors. Zaward provides a practical proposal that turns a design concept into an achievable prototype. We’ll go through all details include the appearance dimension, liquid channel structure, and tube types. If needed, Zaward can proceed with the thermal simulation with our outsourced partners as well.

Vapor chamber

For those who have system space limitation, vapor chamber is an efficient way to dissipate the heat without sacrificing the cooling efficiency. In addition, the vapor chamber can be welded with heat sink to boost its performance. No matter the general standard series or the project-based unique design, Zaward is always by your side to help.

Zaward provides comprehensive product lines of thermal solution. From DC/AC fan, diversified processes of heat sinks, to peripheral components such as heat pipes, fan guards, and thermal pads. We are always well prepared to solve any cooling issues with our best passion for customers worldwide.
