Plate type? Tubular?

What is a plate heat exchanger? What is a tubular heat exchanger?
There’s a lot of information available online; just look around
Simply put, \"plate-type\" and \"tubular-type\" are classifications of heat exchangers based on the shape and structure of their heat transfer surfaces: Tubular heat exchangers transfer heat through the tube walls, including shell-and-tube, double-pipe, coiled-tube types, etc； Plate heat exchangers: Heat transfer occurs through the plates, including spiral plate, plate-and-frame, and plate-shell types
As the name implies, a tubular type involves fluid flowing through small tubes, while another fluid flows outside the tubes, allowing heat exchange between the two. Specifically, there are sleeve type and shell-and-tube type. . . . . Plate type: Simply put, the plate type involves welding several plates together, with different fluids exchanging heat through separate spaces. There’s also the tube sheet type~~~a combination of the above two~~ Ah, it’s hard to put into words

Simply put, a shell-and-tube heat exchanger is a type of heat exchanger that utilizes heat exchange tubes for heat transfer, and it consists of these heat exchange tubes along with a shell ； Plate heat exchangers primarily rely on heat exchange plates for heat transfer; they have a high heat transfer coefficient and occupy less space, but they have limitations in terms of pressure and temperature resistance.
It’s fundamental and covers chemical engineering principles in great detail; it’s worth taking a close look at.
Plate heat exchangers use heat exchange plates as the medium for heat transfer, while tube heat exchangers use heat exchange tubes as such a medium.
A plate heat exchanger is a new type of efficient heat exchanger made by stacking a series of metal sheets with a certain corrugated shape. Thin rectangular channels are formed between various plates, through which heat exchange takes place via the half-plates. In a tubular heat exchanger, the cold fluid flows inside the tubes, while the hot fluid flows outside the tubes via baffle plates; heat exchange occurs between the cold and hot fluids through the partition wall.
