The EXAIR Mini Cooler family is one of the many vortex tube based Spot Cooler products that EXAIR offers. This is the smallest of the group coming in at 550 BTU/hr of cooling capacity. The Mini Cooler Systems are available in two options.
The Single Point Outlet option will give you ten inches of flexible cold outlet to easily position the cold air stream near the target point.
The Dual Point Outlet option gives ten inches of 1/4″ flexible outlet that then splits to two separate four inch lengths of 1/4″ flexible cold outlet hoses.
Both include point or flat fan tips for the cold air outlets
Both include a manual drain filter separator
both include the swivel magnetic base with 100 lb. pull magnet.
The single point hose kit is ideal for small diameter milling or drilling applications where the cold air can cover the contact area of the cutter. It can also be used on soldering, industrial sewing, ultrasonic welding, or even small punching applications to list just a few.
The dual point hose kit is ideal for two separate small diameter cutters, one larger diameter cutter, rotary style knives where there material is being slit, or larger diameter multi-point ultrasonic welders/punches.
When using the Mini Cooler the adjustable cold outlet stays in place and can easily bend around fixtures, spindles, welding horns, or dye aligning pins. The swivel magnetic base gives additional adjustment at the base of the cooler to aid in the versatility of this product. To further the adjustability of the cooler the operating pressure can easily be adjusted to lower or raise the cooling capacity of the Mini Cooler to meet the demands of the precise application.
If you believe you have an application that would benefit from the use of a Mini Cooler, or you are unsure which product would be ideal for your application please contact an Application Engineer. we are all here, willing to help however possible to get your application improved in both safety and efficiency.
One of our clients who produces automated test and assembly equipment for the automotive parts industry contacted me recently with a problem. Their recent project was an automated soldering station. The machine was designed to solder wire leads onto contacts for a motor assembly. The machine worked well at reasonably slow paces. However, when they made efforts to speed up the cycle time, they found they needed to put more heat into the part in a shorter duration of time in order to achieve the desired result for the solder joint. The problem that resulted was the soldering process was imparting too much heat into the connector assembly.
After reviewing the application with our customer, we determined there were two points within the machine that needed to be cooled during each cycle in order to keep the heat from building up in the parts. Given the high heat condition and the short available time for cooling, we opted to go for two of the High Power Cold Guns to blast the part immediately after the heating process for soldering took place. Before the High Power Cold Gun solution was applied, the assembly was climbing to 150C which did not bode well for longevity of the connected components. After the installation of the High Power Cold Guns, the customer was able to have a respectable 30C finishing temperature on the parts before they exited the machine.
The quality issue was more than handled by the cooling capability of the High Power Cold Guns which allowed the customer to continue with their plan to increase productivity with the machine without having any adverse effect due to heat penetrating into the parts. The High Power Cold Guns were controlled by way of solenoid valves to produce the cooling power instantly only at the end of the cycle.
Do you have an automatic or semi-automatic process that could benefit from localized cooling similar to this example? If so, EXAIR has a whole range of Vortex Tube and Spot Cooling Products that can be adjusted to fit your need within the application.
