When it comes to computing hardware, cooling it down is one of the biggest concerns. Hardware cooling solutions have become even more of a concern recently due to the rise in large data centers. These data centers store a ton of IT equipment, computer systems and related hardware. All that hardware makes things heat up quickly. Thankfully, there are many different data center cooling techniques that can be used to prevent overheating for hardware. If you manage a data center, these data center cooling systems are certainly something you want to familiarize yourself with. That way, you can select the best data center cooling technologies for your particular operations to avoid ever having to call a computer repair service. Find out the top data center cooling methods in this post.
Cold & Hot Aisle Cooling
Cold aisle/ hot aisle cooling techniques are one of the most common cooling methods used by data centers. Obviously, this hardware cooling strategy would not be used by so many experts if it was not a great method. But, cold aisle and hot aisle cooling is one of the most inefficient cooling methods around. In order to implement this tactic to cool your data center, you just need to position the racks correctly. Cold and hot aisle cooling methods involve facing inlet rack sides towards outlet sides. Simply put, you create cold aisles and hot aisles that separate cold air and warm air. Modern data centers are moving away from this cooling tactic. But, it is still one of the most popular types of cooling methods.
Chilled Water System Cooling
Chilled water systems utilize liquid cooling methods to prevent overheating at data centers. This is one of the most efficient cooling techniques for data centers. Using this strategy, cold water is directly targeted to specific areas. That way, there is no need to supply air conditioning to the entire data center facility just to keep cool air circulating. In a chilled water cooling system, a chiller is connected to the Computer Room Air Handler, or CRAH. Then, as the cold water moves through coils, it takes on that heat and transfers it to the chiller. Finally when the water returns to the chiller, it merges with condenser water that flows through a cooling tower. This is one of the most efficient data center cooling methods used by many of the world’s biggest data centers.
Pumped Refrigerant Cooling
Pumped refrigerant heat exchangers are joined together with a chiller to cool down the IT environment. These types of data center cooling technologies are referred to as pumped refrigerant systems for chilled water systems, as presented at Oracle Openworld. The data center cooling systems pump a type of refrigerant, like R-134A, through the system without a compressor. This cooling system follows the same steps as a traditional chilled water cooling system. But instead of just pumping chilled water to collect heat waste, refrigerants are added. This makes the system capable of handling larger temperature demands. It also helps to keep water away from expensive IT equipment. Pumped refrigerant chilled water cooling systems are one of the most efficient methods to cool data centers.
In Rack Heat Extraction Systems
In rack heat extraction systems are another popular type of data center cooling tactics that prevents heat from entering into server rooms. These cooling systems work by having compressors and chillers inside racks. Then, that heat is directed to the data center exterior immediately. In rack heat extraction systems are a bit more complex than other types of data cooling methods. It is also difficult to manage and maintain the setup. However, these types of cooling systems help to create the most pleasant IT room environment. This is one of the lesser-used data center cooling strategies. But, it is still one to consider when learning about all the different strategies at your disposal.
Liquid Immersion Cooling
Liquid immersion cooling methods are another type of data center cooling that utilize a coolant fluid. In liquid immersion cooling techniques, a dielectric coolant fluid is used. This fluid gathers heat from all the various server components. Then, it posits that heat in a heat exchanger. This is much more efficient than similar computer room air conditioning devices, or CRAC devices. Dilectric fluid makes it possible to have direct contact with electrical components. This is not possible with other chilled water systems for cooling data centers. If you are concerned about the whole water and electric issue, liquid immersion cooling systems are a great option.
All data center managers know how essential data center cooling systems are to proper data center management. If regular gaming laptop users need to worry about hardware cooling methods, it is obvious that a computing center a hundred times its size will also have to share these concerns. Data centers need to have a great IT room environment to ensure optimal computing performance. There are many different types of data cooling methods to consider, however. Use this post as a guide to the top data center cooling techniques used by the biggest data centers in the world. These cooling technologies will help you maintain a pleasant IT room environment and manage your data center efficiently. Let us know how it works out for you in the comments below.
