Measure out your room. Larger rooms need more heat and some features, such as outside walls, cause heat loss.Exchange api
Use a calculator to determine your exact needs. Figure out how much space you have available for a radiator. Sizing a radiator is easy once you know the dimensions of the room. Once you have these measurements, search for a radiator sizing calculator online, which will calculate how many BTUs of heat you need.

RE: Radiator Sizing? From what I understand the Davies Craig water pump has some problems. Autospeed www. You wouldn't happen to have any personal or anecdotal experience with them would you?
It might be a rumour, as I cannot recall the source of the info. Thanks for the star Greg! Andy RE: Radiator Sizing? Thanks a lot Andy. When in comes to Davies Craig electric pumps, I was going to use one on my project, but the head pressure on the pump is really low, and just did not suit my application.
I don't know what the problem with the pump was, but maybe because of fouling the flow rates are reduced and that is what causes them not to perform. Does anybody know what is a typical pressure drop through an average size engine, such as a 3.
Hey, all my thanks to you Andy. This is great info and definitely very insightful information which I was exactly looking for. Red Flag This Post Please let us know here why this post is inappropriate.

Automotive Radiator - Design and Experimental Validation. It extracts heat from engine and keeps engine surface temperature at optimum level for better engine efficiency. Radiator development consists of its size and design aspects. Size provides heat rejection area and its performance.
Design is related to its robustness.Isocell vs cmos
This paper focuses radiator design validation through finite element analysis as well size and heat rejection validation by experimental test. Coolant surrounding engine passes through radiator. In radiator coolant gets cooled down and re-circulated into the system. Radiator size is controlled by heat load and packaging space availability. Size is verified through 1-D simulation. Based on this size heat transfer rate is calculated which should fulfill the requirement.
Radiator size and heat transfer rate finalized accordingly. Amrutkar, Sangram R. Core dimensions specified. An acceptance criterion is stress level below 60MPa. The tested radiators have similar heat performance. Comparison of Analytical, Simulation and Experimental Performance Results Figure 7: Comparison of Analytical, Simulation and Experimental Results There were some assumptions made in analytical calculations like uniform coolant flow through tubes, uniform temperature of coolant and air throughout etc.
As in practical conditions properties of air and coolant may differ from point to point. Temperature of coolant is changing throughout the core which affect heat transfer rate. Analytical values provide safer side radiator design as actual vehicle running conditions are unpredictable.
FE Analysis result shows radiator design is safe and stress level observed is below maximum stress criteria. Performance test result shows radiator is able to deliver required heat rejection. Shilwant values found experimentally. The objective to design and validate the radiator is accomplished successfully. Esmaeili Sany, M. Saidi, J. Shilwant 3.

Before we start reviewing the charts, we have to talk about how radiator performance is measured. The fundamental rule of radiator performance testing is to see how well the radiator cools the coolant. But still, what does all this mean!? By looking at the chart, to cool and overclocked high-end GPU and CPU, that altogether dissipate around W, would require crazy fan speeds.
But what would happen if we slow the fans down? Now here is the twist. If the temperature of the liquid rises inside the radiator and the ambient temperature remains the same, the radiator will have a greater cooling capacity. Higher liquid temperature means the radiator becomes more efficient and can remove more heat.
If you are having a hard time understanding this, imagine that the greater the difference between the ambient temperature and the liquid temperature, the more efficient the radiator gets. You can see how the three radiators relate to one another at various fan speeds.
You can spot that the thicker the radiator is, the better it responds to faster fans, i. Only with a slight change in the fan speed, the XE radiator gains much more cooling power than the Slim model. You can also spot that, at low fan speeds, all three radiators perform almost the same — within the 50W cooling capacity range.
The jump in cooling performance from a radiator to a mm one is more than evident. At a fairly low fan speeds, the SE Slim radiator can cool W more that the mm Slim radiator. Again, we can see that the bigger and thicker the radiator is, the more it gains from the higher airflow. Do you just want something more efficient than air cooling? Do you want silence? Do you want to overclock your hardware? Do you want a silent PC and overclocked stuff at the same time? Going for a bigger radiator comes down to your personal needs, what components you are cooling, are you overclocking, do you want a silent PC, etc.
Radiators are by far the most demanding water cooling components when it comes to testing and measuring their performance accurately. For these reasons, we have used radiator test results that were conducted in a controlled test environment. The final results that you, the user, can get at home might differ from these charts because of variances in the pump flow rate, the type of fans used, the type of case and how well it is ventilated, the choice of water blocks, the quality of the thermal compound, etc.
The number of variables is vast and the point of these charts is to show you how certain radiator sizes and models relate to each other. We would wrap it up here and leave the rest for the episode 3. In our next blog post about radiators, we will be talking about surface size over thickness, or which one is better.
Everything depends on everything. Of course, as I said everything depends on everything. Every cooling loop is unique and these charts are made in a controlled environment just to have a representative chart about radiator performance for comparing.
Radiators Part 3 – Small and thick or slim and big?
Hope this helps. This would make checking the approximate cooling efficiency much easier — than having to do the same conversion anyway — when trying to compare it to the aprox.

Share on social: Facebook Twitter.Time to continue the story about radiators for liquid cooling. We have covered the basics about radiators in the Part 1 blog, and in Part 2 we even showed some charts. Part 2 clarified things about radiator performance, how radiator performance is expressed and how do we read radiator performance charts. We have shown how two of the most popular radiator sizes and mmwith different thickness variants, relate to one another performance-wise.American megatrends bios master password
In this episode, Part 3, we are going to address a very important question. What is more important for better cooling?
A small but thick radiator or a large but slim radiator?
Radiators Part 2 – Performance
Still, if you are an experienced liquid cooling user, and you already know the answer, maybe now you have a chance to see concrete results presented in some nice charts for the first time.
In the chart above, we can easily see how the slimmest SE radiator beats the thickest XE in every aspect. If you are after a silent liquid cooled build, and you have the option to mount a mm radiator, by all means, the SE is the way to go. Many presume that thick radiators are packed with super-powers and will bring extreme cooling performances, but things are more complicated than that.
But why is it so? In previous radiator blog posts, we already talked about how radiators work. In a push configuration, cold air is pushed in by a fan from one side of the radiator and warm air leaves at the other side of the radiator.
Heat is being transferred from the liquid to the radiator fins, and onto the air that is pushed through by the fan. Imagine that an XE 60mm thick radiator is actually three slim radiators packed on top of each other.
If you remember from our Radiators Part 2 blog, the greater the difference between the coolant temperature and the ambient temperature, which is the temperature of the air passing through the radiator, the better cooling performance you will have.
So… by using a thick radiator, the bottom part of it, in this case, will have better cooling while the top is less efficient. The chart above shows that the XE will catch up with the slim SE only if we crank up the fan speeds. Let us look at some extreme comparisons. If we compare the super thick single XE with the slim triple SEwe will see how much advantage a bigger cooling surface has over a small thick radiator.
Predictably, the PE will sit in the middle of these two. Therefore, even though we can look at the XE as a slim SE that is chopped up and stacked in three layers, it is not even close to the slim triple radiator regarding performance.
Not many cases offer support for a mm radiator, which is the reason why the mm form factor is more widespread. But it all comes down to the personal choice and case limitations. Very good blog post, very informative.The two major areas of engine development, the automobile industry is concentrating and putting its major product development efforts on are emission control and improved fuel efficiency. These developments either directly or indirectly impact the cooling system requirements significantly.
A small change in cooling system requires the vehicle to undergo cooling tests before commercial release to make sure it performs as per requirements. Normally, on an average, trials are conducted before clearing the vehicle for production.
This involves a lot of time, efforts and resources. The objective of this study is to develop a methodology to predict the cooling system performance analytically and validate the results with experimental data. This study will help in reducing the number of trials thereby saving cost, time and efforts involved. Basic components of cooling system include radiator, charge air cooler and fan.
The most important parameters used to validate the analytical results are the Limiting Ambient Temperature LAT and charge air cooler outlet temperature. LAT is the maximum ambient temperature at which the vehicle cooling system can work without failure. The Steady-state analytical calculations have been performed for engine cooling system Radiator - Charge Air Cooler CAC - Fan combinations using lumped parameter approach and the methodology is validated experimentally.
The deviation between the proposed analytical method and test is reasonable. FAN laws are used to evaluate fan performance for different speeds of engine.
