K Corp., a medical equipment manufacturer, had recently started to develop a new model of their medical testing equipment. Mr. D, director of K Corp.'s development department, talks about the challenges he encountered:
"The miniaturization of medical testing equipment is an important factor in enhancing competitiveness. For our new model, reducing the size of the equipment while maintaining performance was essential. Our previous model used a 60 × 60 × 25 mm cooling fan, but with the new model being smaller there was not enough space for the current fan. We needed to find a smaller fan that had the same cooling performance as our current fan."
K Corp.'s development department continued to search through catalogs and websites for a fan that met their requirements.
Mr. D visited the SANYO DENKI booth at an industrial equipment exhibition. After discussing his problems with a SANYO DENKI representative, Mr. D agreed to continue the discussion in detail at a later date.
On the day of the meeting, the SANYO DENKI representative brought an Airflow Tester to measure the prototype.
"We had looked in the catalogs and on the website for a smaller fan than the one we had originally used, but it was difficult to find a fan with the same cooling performance. The representative measured our system with an Airflow Tester to determine the cooling operating points and select the most appropriate fan. They found that a SANYO DENKI 60 × 60 × 10 mm fan, which we had not considered a candidate when we initially looked at the catalog, could cool the system sufficiently. It seems that because the cooling performance of a fan mounted in a device depends on the mounting density of the device, it can't be judged using the catalog alone. The fan they suggested is 60% thinner than the one used in our current model, and it can be installed in our smaller model," exclaimed Mr. D.
Mr. D immediately ordered samples using our short lead time service and tested them in their prototype. After that, K Corp. decided to use the 60 × 60 × 10 mm fan. Development of the equipment progressed smoothly, and the completed new model was significantly smaller.
"It was very helpful to have a sample available right away, as development time was so limited. As a result of the actual equipment evaluation, we confirmed that the 60 × 60 × 10 mm fan could meet our desired cooling performance. We really appreciated the flexible response from SANYO DENKI, especially the airflow tester measurements. We would be happy to consult them again in the future," beamed Mr. D.
