What data do you need to offer to us, when you ask us to design the pillow plate heat exchanger?

If you want our engineer to design the pillow plate heat exchanger for you, what datas do you need to offer?

1. Things to know about fluids in pillow plate set upsWhat the fluids are: the hot and cold fluids. It could be water, oil, steam, or some chemical liquid. Different fluids have different physical and chemical things about them. Like how much heat they can hold (specific heat capacity), how heavy they are (density), how thick they are (viscosity), and how well they can move heat (thermal conductivity). All these things change how the heat exchanger works. For example, water can hold a lot of heat. When it moves heat, its temperature doesn't change much. But oil is thick, and that can make it hard to flow in the channels.How fast the fluids flow: how fast the hot and cold fluids are moving. We usually say this in units like cubic meters per hour or kilograms per hour. How fast the fluid flows decides how fast heat is moved and how big the area for moving heat needs to be. If the fluid is flowing really fast, we might need a bigger area to change the temperature the same amount. Fluid temperatures at the start and end: We need to know the temperatures when the hot fluid comes in and goes out, and also for the cold fluid. These temperatures help us figure out something called the logarithmic mean temperature difference (it's like how much 'push' there is for heat to move). This is really important when we're deciding how big the heat - moving area should be. For example, if the hot fluid comes in at 100℃ and goes out at 60℃, and the cold fluid comes in at 20℃ and goes out at 40℃, we use these numbers to plan and calculate later.Fluid pressure: the pressure when the hot and cold fluids come in and go out. This helps us design the heat exchanger to make sure it can hold the pressure of the fluid without breaking. Also, pressure can change the state of the fluid. Like, it can make the fluid turn into a gas or not. This is important because it changes how heat is moved. For example, when the pressure is high, the fluid needs to get hotter to turn into a gas. We have to think about this when we're designing how heat is moved if the fluid might change its state.Other fluid properties: how heavy the fluid is (density), how much heat it can hold (specific heat capacity), how well it moves heat (thermal conductivity), and how thick it is (viscosity). All these things change how the fluid moves and how heat is moved in the heat exchanger. For example, if a fluid is really thick, it's hard for it to flow in the channels. We might need to make the channels in a special way to make it easier to flow. And if a fluid can move heat really well, it helps with the heat moving process.

2. Parameters for How Well It Should WorkHow well the pillow plate should move heat: Customers might want the heat exchanger to work in a certain way. For example, they might want the cold fluid to get hotter by a specific amount, or the hot fluid to get cooler to a certain temperature. This decides how we design and choose the heat exchanger. We need to make the right heat exchange area and design the channels where the fluid flows to make this happen.How much pressure can be lost: When the fluid goes through the heat exchanger, it loses some pressure. We have to know how much pressure loss is okay. If too much pressure is lost, it can mess up how the whole system works. For example, the pump might need to work harder (use more power) to keep the fluid flowing at the right speed. If we design the channels where the fluid flows just right, we can make sure the pressure loss is within the okay range and still keep the heat moving working well.

3. Stuff about the Place It Works InHow much space there is to put it: We need to know how big the space is where we'll put the heat exchanger. We have to think about how long, wide, and tall the space can be. This will tell us how big and what shape the heat exchanger can be. If the space is small, we might need to pick a design that takes up less room. Maybe a design where the parts are folded or a design with lots of layers for the fluid to flow through.How hot, cold, and wet it is around: The temperature and how much water is in the air around the heat exchanger can change how well it keeps heat in or lets heat out. If it's really hot or cold outside, we might need to do something extra. Like if it's very hot, we might need to add something to help it cool down so it can work right.How often it works and for how long: We have to know if the heat exchanger works all the time or only sometimes. And we need to know how many hours a day or how many days a year it works. This helps us pick the right materials (because some materials might get worn out faster if it works a lot) and when we should check and fix it. If it works all the time, we might need to use stronger materials and check it more often.

4. Things about the Materials NeededWhat materials are wanted or not allowed: Customers might have special ideas about what the heat exchanger should be made of. They might say we have to use things like stainless steel or titanium alloy. This could be because they need it to not rust easily, or because it has to be really clean (like in the food or medicine making). Different materials can move heat at different speeds, they're not all equally strong, and they cost different amounts. So we have to pick the right one based on what the customers need.What to do to the surface: If there are special things we need to do to the surface of the heat exchanger, we have to know. Like, we might need to make it really smooth by polishing it, or put on a special paint to stop it from rusting. Doing these things can make the heat exchanger last longer and work better. It can stop it from rusting and keep dirt from sticking to it. For example, in the food industry, the heat exchanger has to have a smooth surface so it's easy to clean and stays really clean.
