Outdoor signs are also increasingly being replaced with digital signage. In response to this, Company H launched a project to develop a new model of digital signage that can be installed outdoors and is thinner than current models. Mr. K, the engineer in charge, said the following:
"Digital signage has a light source, so the inside of the device can get very hot. Originally, we used axial fans to cool the high-heat light source inside the narrow space of the device. However, by making the device thinner, the air convection inside the device became poor, and the cooling performance of the current axial fans was no longer sufficient.
The mounting space for the new model is even more limited, so we felt that the cooling provided by the current axial fan had reached its limits. In addition, since the new model can be installed outdoors, it also needed to be waterproof so that it could be used without problems in rainy weather.
Mr. K searched for an axial fan that met his requirements, but he was at a loss when he could not find a fan that met all of his requirements in terms of size, cooling performance, and waterproofing.
Mr. K was having difficulty finding a fan that met his requirements, so he consulted with a person at SANYO DENKI CO., LTD., with whom he had previously done business, and was suggested Splash Proof Centrifugal Fan.
"Splash Proof Centrifugal Fan that was proposed to us is different from the axial fans that we had used up until now. Instead of blowing air backwards, the direction of the air changes by 90 degrees from intake to exhaust. It has particularly high static pressure performance, which is advantageous for cooling equipment with a high mounting density. In addition, because the fan is only 35 mm thick, it can be designed like a heat exchanger to provide efficient cooling even in a small, thin space.
Furthermore, regarding the other issue of waterproof performance, we were able to confirm that the IP54 protection rating means that outdoor use is no problem," said Mr. K.
"When we evaluated it, we found that the cooling performance was more than adequate. In fact, there was even a little margin for error. Another key point was PWM control function that comes standard with the fan. It can be controlled to the optimal rotation speed according to the surrounding temperature, which helps reduce power consumption and noise.
Furthermore, because the new model has a larger screen size, the fan mounting position and the power supply unit were far apart, but they were able to flexibly customize the connectors and lead wire lengths to suit the device structure." (Mr. K)
Up until now, Company H had been using axial fans for their digital signage, but after this development, Mr. K had this to say:
"This was the first time we used Splash Proof Centrifugal Fan, and I believe this was key to the success of the project. We will be developing new models in the future, so we look forward to receiving further proposals from SANYO DENKI CO., LTD.." (Mr. K)
