China International Industry Fair 2012 is going to be held during November 6th through 10th, 2012 at Shanghai New International Expo Centre. Theme Shows will be held concurrently under CIIF 2012. CIIF 2012 will occupy 150,000 sq. meters as its display area and attract more than 1,800 exhibitors and 100,000 trade visitors.
Euro-me Shenzhen Trade & Development Co. will be exhibiting at the Industrial Automation Show (one of the themed shows) within the CIIF Fair. They will be located at booth number W1D001.EXAIR Corporation will be supporting our distributor by sending Neal Raker, Application Engineer to attend the exhibition with our Chinese partners. EXAIR products will be on display and available for demonstrations at the booth. If you have an application you would like to discuss, there will be plenty of people on hand to help you determine the best solutions.
EXAIR’s official, Israeli distributor, Dip. Ing. M. Gutmark Ltd. will be exhibiting at Plasto-Ispack in Tel-Aviv, Israel. Their booth will be located at Hall 10, Stand #3. The exhibition runs from October 16 – 18, 2012 at the Tel-Aviv Exhibition Center. Gutmark Ltd. will have EXAIR products on display, ready to demonstrate.
Every three years the Exhibition offers those in the field, in Israel and abroad, the opportunity to get acquainted with the exciting developments in Israel’s high tech plastics, rubber and packaging industries, leaders in the Middle East. It is an opportunity to be updated regarding the latest innovations in the field and to make business contacts, both local and international.
A Vortex Tube cooling kit is helpful when flow and temperature requirements are unknown. The experimental kit affords you the flexibility to determine your cooling needs.
I recently had a customer e-mail me with this inquiry. Following is our discussion:
Customer:
We have a small vortex (3208) and a set of generators, the one that is pre-installed in the Vortex Tube (8GR) and a few more:
2GR, 4GR, 2GC, 4GC, 8GC
Maybe you could tell me the effect of these generators on the cold flow.
My main application is to refrigerate tools during machining or cool ultrasonic transducers during continuous operation. My compressed air source is 6.5 BARG. Using the Vortex Tube as it comes, after closing the hot flow and opening it a revolution, I can reduce the temperature from 22ºC (room temperature) to -6ºC (measured in the cold air flow at the output). How do I use the flow generators?
EXAIR:
Thank you for your question concerning the generators which are interchangeable on the Vortex Tube. The purpose of the various sizes and types is explained as follows:
GC vs. GR designation: The GC type generators are designed to achieve maximum temperature drop for applications which may need an airflow which is below 0 degrees F. It is unusual that an industrial cooling application would need air this cold, but some scientific and other similar academic pursuits do need air flows that cold. The thing you give up when you try to achieve low cold temperature is the flow. Flow and temperature drop are inversely related to one another with a vortex tube’s function.
The GR type generators are used for temperatures down to zero degrees F. So, these would be the more prominently used generators for industrial applications. We usually will set up a Vortex Tube in a cooling application to have about 50 degree F temperature drop and can still preserve 80% of the total flow for cold flow applications. This is what we refer to as maximum refrigeration settings.
As for the numbers on each generator (2, 4 or 8) this is the indication of the amount of air volume consumed by the Vortex Tube when this specific generator is installed. The flow rate is indicated in SCFM with 100 PSIG inlet working pressure. So an 8 SCFM @ 100 PSIG flow rate is what is determined by an 8-GR or 8-GC generator. Small Vortex Tubes are available in flows of 2, 4 or 8 SCFM.
Basically, the larger your flow rate, the more cooling power you can generate. Think of the cold air as ice. Think of 8 SCFM as a 55 gallon drum of ice and a 2 SCFM as a 5 gallon bucket of ice. Both have the same temperature, but the 55 gallon size has potential to do more work to cool down a larger heat load.
Creating a spot of heat with a torch or an electric heating element is not hard to do with common tools found in a manufacturing environment. Creating a spot of cold air for similar situations is a very tough thing to do in the same situation. A Vortex Tube is a handy and convenient tool to allow for the spot cooling or small chamber cooling applications.
If you have a spot cooling application you think we may be able to help with, please contact us by e-mail,chat, Face Book, Twitter, phone or fax. We will be glad to assist.
As the title suggests, I wish to quickly visit a simple and effective cooling application with you. The customer builds custom test fixtures to test any electronic circuit board and components prior to final assembly of the board into whatever it will be used in. Their requirement is to cool an IC processor chip that would normally have a heat sink and a fan to cool them once fully assembled. During board level test the heat sink and fan are not there, so to keep it cool they want to use a Vortex Tube cooler. Physically, the test parts will range in size from 2.25″ square to 1.125″ square with a height of around .156″.
I recommended the customer incorporate our Model 5215 Cold Gun System into their test fixture to provide the necessary cooling. The reason for recommending this model over a plain vortex tube is that it is supplied with all the necessary heat shielding and sound muffling accessories anyone using a vortex cooler would want for ease of use. Besides these features, the Cold Gun comes with a magnetic base to mount the unit and also flexible tubing to allow for aiming of the cold air flow precisely where it is needed.
The customer incorporated the Cold Gun into their test rig and found it to be quite useful and fast at cooling the target.
That, my friends, is a straight forward Vortex Tube cooling application.
