how to determine car radiator size
When getting overall measurements its from "Tank to Tank" and "Band to Band". Step #1. Copyright © 1998-2020 engineering.com, Inc.

Keeping our warfighters safe and delivering them a competitive advantage is a key goal of departments of defense around the world. You will be measuring the core only. Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. As I read, that would be about 1/3 of total power, which assuming 1/4 only goes down to the groud, that would mean almost 200kW gets transfered to the coolant. I found it very dificlut to find any information, data, U, effectiveness, etc on automotive radiators, if anybody can provide me with a good source, website, book for this type of data that would be great.

Just thought that if cymeryss didn't really know anything about engines, then knowing % heat rejection to coolant for a modern engine may be of use. Solutions Brief - Protecting and Rescuing On-Ground Personnel, White Paper - Cobots vs Covid: Today's Manufacturing Reality and Tomorrow's New Normal, Datasheet - Creo Generative Topology Optimization Extension. There are formulas to determine appropriate radiator size based on engine heat output (operating BTU's) and radiator heat-transfer rates (also stated in BTU's). It might be a rumour, as I cannot recall the source of the info. Does anybody know what is a typical pressure drop through an average size engine, such as a 3.0L V6? Close this window and log in. (engineers have all ready solved the problem for you) What size radiator is in there? Andyv8's post is relevant and I gave it a star. This is great info and definitely very insightful information which I was exactly looking for. Equation for Calculating Car Radiator Size.

2. andyv8 (Automotive) 27 Apr 04 05:35. It’s a goal shared by embedded computing manufacturers like Abaco: we never forget who we serve.This case study describes how a major international contractor integrated an Abaco single board computer at the heart of its CAS/CSAR solution. Autospeed (. Getting the Overall Radiator size. MEASURE ONLY THE CORE to determine the size of the radiator. Before you measure a radiator, make sure it is in the upright position. 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. RE: Radiator Sizing? There's your answer. Measure only the core to determine the size of the radiator. Hello, Is there any way to calculate how big the radiator must be? To start would two flow conditions be sufficient, for example at idle, and at max power output, in order to size the radiator? Thank you for helping keep Eng-Tips Forums free from inappropriate posts.The Eng-Tips staff will check this out and take appropriate action. Chumley . With Creo 7.0, you will be able to design the most innovative products faster than ever before, keeping you on the cutting edge of product design and ahead of your competition. There's your answer. What is a typical heat transfer coefficient, U for an automotive radiator of average size 3.0L? There are a few things to consider before we single out the radiator as a cause of the cooling issue. You really don't have to reinvent/redesign the wheel. First of all what would be a good assumption for how much heat is dissipated to the coolant from the IC engine. Login. The remainder of your cooling system and engine should be in proper working condition; meaning the appropriate pulley ratios adequate airflow, proper thermostat, correct ignition timing, air/fuel ratio, vacuum and mechanical advance curves, etc. Increase or decrease that value by the following factors: ADD. Start with 2 cubic inches of core for every cubic inch of engine.

Just go and look at a similar sized car with a similar sized engine. See how the Generative Topology Optimization extension automatically delivers high-quality, lower-cost, manufacturable designs. Multiply the square feet of the one section by the number of sections. As you can see, heat to coolant is  nearer 1/4 of ouput power. Click Here to join Eng-Tips and talk with other members! t Measure height of section t Measure width of section t Find square feet of section in Chart # 1 for COLUMN or Chart # 2 for TUBE type radiator Step #2. PTC's Creo 7.0 has breakthrough innovations in the areas of generative design, real-time simulation, multibody design, additive manufacturing, and more! (Thanks for the star Greg !).

From what I understand the Davies Craig water pump has some problems. To get overall thickness measure the tank thickness only. Promoting, selling, recruiting, coursework and thesis posting is forbidden. Core Height: This dimension is always measured in the direction from top to bottom, from the sky to the ground, as shown in both diagrams above. Water cooled cars with radiators have been in existance for over 100 years. How to calculate radiator size?

The reason I thought it was relevant was that it gave real numbers for the proportion of the energy going into the coolant, which I thought was probably a handy number if you are designing a radiator.

*Eng-Tips's functionality depends on members receiving e-mail. Thanks a lot Andy. By joining you are opting in to receive e-mail. Just go and look at a similar sized car with a similar sized engine. Only the core is measured to determine the height of the radiator, do not include the side rails. Radiators are normally sized to achieve steady state cooling at maximum torque, but this is not very realistic unless you are towing. need to be addressed. 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. A. Rapidly explore innovative design options to reduce development time and expense, all within the Creo design environment. Example, I've taken a csb 350 from a corvette and want to use it on my model a. Thanks for reading. Calculate the square footage of one section of the radiator. No, But I think I saw somewhere that they are supplied to Jaguar as OEM on at least one model. Please let us know here why this post is inappropriate. I know there are lots of variables in this problem such as the coolant flow rate, air speed, radiator heat transfer coefficient, etc, and detailed analysis would be needed to properly size the radiator. For example, lets take a 200hp, turbocharged engine, 1.8L, 4cyl motor. For a high output n/a 3.0L V6, here's a heat balance (based on dyno data).

I am looking basically for a worst case scenario. Didn't measure the pressure drops, but flow rates were as follows for the V6: Hey, all my thanks to you Andy.

This white paper shows how collaborative robots can play a role in helping companies succeed in the Covid-19 world: to help with social distancing, ramp up new lines quickly and reshore existing products due to interrupted supply chains. Water cooled cars with radiators have been in existance for over 100 years. Regardspat   [email protected], by professional engineers for professional engineersPlease see FAQ731-376 for tips on how to make the best use of Eng-Tips Fora. Now, at steady state, are radiators sized to cope with this condition or some precentage of that?

I am aware that this is a very broad question, but was wondering if there is an approximate method to evaluating a needed radiator size? It have to fit into the 29 shell so that size is maximum. Already a member? Already a Member? The core is the central part of the radiator (between the tanks and the side-pieces) and consists of parallel rows of tubes and fins.

(engineers have all ready solved the problem for you)  What size radiator is in there? Real-world case studies are provided. Please note that when measuring your radiator that you don't incude the filer neck or any mounting brackets/ hardware. The Corvette rad is way to big to fit into the 29 rad shell so i have to use another one..
