I don't know much about it so I wonder if you all can help. The system has no compressor? No true condensor? Is The whole system what is pictured in this cartoon:

If so, I might look into this for computer cooling. Computer temperatures are on the rise as fast as technology and the market is about to transfer to water cooling. I am thinking of trying to plan out a system one step ahead of the market and maybe making some cash out of it. Of course one company is about to market a heat pipe fan but I think if I got the hang of this I could do something.

I've worked with them in energy recovery applications. Half of the unit is installed in the exhaust air stream and half in the supply air (O/A) stream. The effect is similar to a heat wheel only there are no moving parts. Older versions were tilted to switch between summer and winter operation, but the new ones are stationary. They work really well when you have two airstreams with a sizeable temperature differential.

Heat pipes are being used on grocery stores make up are units, among other things, now.

The application you show is the first link is for extended latent heat rmoval.
Computers are high on sensible heat with little or no latent factor.

The second link is using a heat pipe to transfer the heat from the chip surface. That may or may not, be anything more than a marketing gimmick.

This is a typical heat recovery, heat exchange system, etc, etc used in many applicaitons over the years. It's not a true cooling system that you will need to remove heat from computer rooms or other heat producing situations.

Large auditoriums, kitchens, swimming pool areas have used this for years.

These may work well.

The illustration shows heat pipes wrapped around a cooling coil. You could use this for a high latent load, for increased dehumidification.

The system illustrated precools entering air sometimes to the point of condensation occuring. The air leaving the precool coil, then has a lot of moisture removed by the cooling coil. The heat removed in precooling is transfered to the reheat coil downstream of the cooling coil and the air is reheated.

A computer room would not have the high latent load and would not use a heat pipe system.

Without compressors the two sets of heat pipes would be in separate air stream for heat recovery as mentioned by others.
