I've never heard of standard heat pipes, probably they're like heat sinks: you buy them in standard sizes, or you'll have to design your own and have it manufactured at prohibitively high costs.

Perhaps not an option in your application, but if I were you I'd look for a higher power diode (in TO-3P package for example) which can be cooled with a heat sink alone. The combination of a heat sink and an off the shelf fan will be much cheaper than a heat pipe I have the feeling.

My Dell Inspiron laptop contains a heatpipe. It would not be evident except the techie I purchased it from pointed it out to me while it was open.

It is custom shaped, conveying heat from the central area to an outer edge of the enclosure.

I think the idea is that the congested central area is not convenient to place a cooling fan, and vents. Too much obstruction. Insufficient air circulation.
