How about a design that mimics a turbine, not a squirrel cage? The fins would be canted drawing air straight in. Couple that with a scoop and a heat shield.

So a little bit ago someone started a thread about those racing fans that overheat engines. I found another type of fan that looks stock but suppose to be better and i posted a link to it and pics and people from here said the blades were reversed. So i send the manufacturer a message telling him what others have said about the fans and this was what he wrote me back today. What do you guys think? Dear scooterelements, Dear Sir, I had to tell you one secret, the GY6 old stock cooling fan was a wrong design about 30 years ago, that's why GY6 engine always overheated. The old stock fan would inhale the hot air into the engine while it exhaust the hot air, so the engine always inhale hot air, there are no cool air into it, so the engine would be overheated. That's why now many scooter factories in Taiwan who use GY6 engine (like SYM) change the old stock cooling fan design, the new stock cooling fan is clockwise design, like ours fan (you can see as follw photo). Our high flow cooling fan blades were calculated and tested very precisely when our engineer designed them, so it never become what you said. To see is to believe, i can present some our cooling fans to you for testing, but you have to pay the shipping fee. I believe that if you test them, you will love them, and never use the old stock design. How do you think about? And do you know propeller is one of our products? So scooter cooling fun is a piece of cake for us. Waitting for your response.  I would be comfortable using any of these fans, blades are going the correct direction on all three... I didn't even know HP fans had reversed blades, until one day trying to figure out my over heating problem I just happened to notice it by accident... |
