Sandia integrates fan and heat sink

[Tecnho]

If it comes out I would like to try it, but as kynes says what a danger, maybe a radial is safer XD.

@cobito:

I want to assume that the innovation comes in the contact between the heatsink and the base. Because if the biggest achievement has been to make a heatsink that spins… :osvaisacagar:

In that case the biggest achievement would be to sell it to us :ugly:

We will assume that these blades are more blunt than the "cantounlibro" unless they have some kind of "secret" connection with prosthetic manufacturers.

[kynes]

They would have to sell them with a "cage" to prevent accidents. No matter how flat it is, at 2000 rpm it cuts you.

[Tecnho]

You have probably thought about it, but it may not give you the performance you expect, however, if it is commercialized, they will put a good "do not touch" sign due to the risk of amputation.

[kynes]

Yes, the physical principle makes sense, it's just that the dissipated power remains inside the box.

[Sylver]

Kynes, for that perhaps with wire mesh type fabric they can solve it without losing performance, right?

[kynes]

Yes, but it must be rigid enough that no one can bend it enough to interrupt the rotation. A metal fan at 2000 rpm rubbing against metal mesh can be funny XD

[Tecnho]

Jajaja, it would light up the room well and with a characteristic smell.

[Sylver]

Man, I mean, if someone takes pleasure in deliberately forcing the mesh inward until it touches the blades, it's because they have a neuron deficit... xDDD

Man, I mean, if someone is having fun forcing the mesh inward on purpose until it touches the blades, it's because they have a neuron deficit... xDDD

Never doubt the skills of the user :troll:

The modding potential is infinite. Imagine a PC throwing sparks from the heatsink :ugly:

man considering that it spins clockwise I don't think it's very dangerous or at least not more than a fan spinning at 5400 RPM

A metal surface spinning at 2000 rpm I assure you that at least it will buff your finger, even if the direction of rotation is favorable to you. Even more so if it is an irregular surface, such as the blades of a fan.

Put a metal disc on a drill, see if it hurts you or not.

[Franziskaner]

the fact that it is metallic does not imply that it cuts or that it grinds or polishes anything, if it were to rotate in the opposite direction to the hands of a clock it would have some danger. or more graphically, if you put your finger in a fan on the side where the air comes out, nothing happens to you, but if you touch it on the side where it takes in air, you can get hurt ;D an aero cool shark at 1500 rpm gets hurt because of the design of the blades, and a typhoon at 5400 I don't think I would try it. anyway, if it were a small radial or a multi-lip cutter, it would have some kind of protection and not be "in the air". the only "area" I see as dangerous is the central part (where it takes in air)

regards

[kynes]

The fact that it is metallic implies that it has much more momentum, that it is not deformable, and that it is not stoppable like a plastic fan. Just that. Stopping a bicycle at 30 km/h is much safer than trying to stop a car at 30 km/h. What worries me is not the rotational speed, it is the energy it transmits per unit of surface.

que no es deformable, y que no es frenable como un ventilador de plástico

hombre deformable es cualquier material , otra cosa es que tenga memoria o no
frenable ¿? el ventilador de plastico lo paras por que el motor eléctrico no tiene suficiente fuerza o las aspas la suficiente inercia ( poca masa ¿?) no por que sea de plástico o metálico .
sobre cortes y demás , lo mismo me da cortarme con un cacho de formica que con un cacho de chapa de hierro o con un papel se que todos cortan , si los manipulo in adecuadamente
en cualquier caso aqui lo interesante es que eso funcione y punto que ganas tengo de que este mundillo evolucione un poco y dejen de vendernos cacharros asi Profesional Review » Review: PHANTEKS PH-TC14PE

Para dejar bien claro su peligrosidad: el ventilador de stock normal y corriente de mi PC2 (Athlon64 3000+) va a unas 2500 rpm, aveces más aveces menos… Cierto día lo tenía abierto (y funcionando) y me percaté de que se le había enganchado un cable de alimentación (sólo un hilo) entre las aletas del disipador, por uno de los lados. Allá fui con valentía a retirarlo, para evitar cualquier percance, y sin querer toqué con la llema de un dedo el ventilador en marcha... Me pegó tal latigazo que literalmente me incrustó el aspa en la llema del dedo, salió, y me levantó un par de centímetros de carne. No fue un rasguño, sangraba en abundancia... :wall: Desde entonces le tengo bastante respeto a todo ventilador en movimiento, por pequeño que sea.

pues tuviste suerte de que fuera un ventilador normalillo. el año pasado yo toque sin querer un aspa de un gentle typhon a 3000rpm y me arranco la uña de cuajo, y eso que estos ventis tienen las aspas bastante gruesas y con los bordes redondeados

Vuelvo a repetir, lo que te hace daño es la cantidad de movimiento, no la velocidad. No es lo mismo que te impacte una pluma a 100 km/h que una bola de cañón a 100 km/h. Es física de colegio.

Si ese golpe os lo pega un ventilador con aspas metálicas, más que probablemente no os quedara dedo, quizás no os queda mano.

Tenéis razón los dos, la energía cinética depende de la velocidad y de la masa. Por lo tanto cuanto mas pesen las aspas y mas velocidad lleven mas limpio sera el corte.
