An efficient Platecoil heat exchange plate
Thread Content
The platecoil heat exchanger plate is a fully welded plate-type heat exchange structure, formed by welding two stainless steel plates together and then expanding them. Media such as water, steam, or heat transfer oil can flow through it. Thanks to the design of its weld points and flow channels, it offers a higher heat exchange efficiency compared to traditional tubular heat exchange structures; moreover, it has a smaller overall volume when having the same heat exchange area and the same spacing. It is widely used in fields such as heat exchange of solid materials and gas heat exchange.
This structure does seem to have a high heat exchange efficiency; how is its pressure resistance?
Plate exchanger is a broad term; this type is also plate-based, but it is not the same as a plate exchanger used for liquid-liquid heat exchange
The internal pressure can withstand up to 30 kilograms, and the external pressure is even higher
1 For the entire device, the internal pressure it can withstand depends on the pressure-resistant casing； Regarding the pressure between internal plate passes, attention is paid to the pressure difference between the two media. 2. Judging from the photos: if the distance between the bulged points is small and the plate thickness is large, then the pressure difference exerted by the medium acting on it will be high. 3. Whether what the original poster said on page 4, that it’s “not the same thing,” refers to a broad or narrow concept remains unclear; at least from the photos, it appears to be a plate used in heat exchangers, and it’s clear that fluids such as water, steam, or heat transfer oil can flow through it. If the two fluids inside are water and heat transfer oil, isn’t that liquid-liquid heat exchange? If the dimensions differ only due to a specific operating condition, that is a different matter. 4. If the original poster is available, they might as well explain it so that everyone can know; if it really is a good thing, it shouldn’t be missed.
1. About 20 minutes ago, I posted a reply in this thread that contained purely technical opinions and did not address any controversial or sensitive topics. After posting it, I was told that it needed to be reviewed; upon checking again, it seems that approval for publication was not given, so I assume the review was rejected. Within 10 minutes, we communicated on another topic, and it was sent successfully; I’m not sure what happened. 2 If I’m not going to say it, then I won’t.
This is somewhat similar to a Miller plate. Is there any significant difference in cost between it and detachable plate exchangers? Let’s get to know each other; add me on V
Can this type of plate be rolled into a cylinder and pressed into a head?
