Plate heat exchangers and shell and tube heat exchangers are two of the most common types of heat exchangers, and both play an important role when heating or cooling wort during processing. In the new era of sustainability, saving energy and reducing environmental impact has become increasingly urgent. By using a plate heat exchanger, energy can be transferred between two fluids at different temperatures. This increases efficiency through heat transfer.
A heat exchanger is a circuit element that transfers heat between two fluids (liquids or gases) with a temperature difference (without mixing) and without any physical contact.
Heat exchangers are generally classified into three types:
Tubular heat exchangers
Plate heat exchangers
Special application heat exchangers
If you have worked with liquid cooling products before, you will have come across two options: shell and tube heat exchangers and plate heat exchangers. Shell and tube heat exchangers and plate heat exchangers work on the same principle, exchanging heat between two fluids by conduction, but they are constructed very differently.
A shell and tube heat exchanger consists of a bundle of thin tubes within a shell and is a simple yet effective construction. The principle is old. Due to their simplicity and flexibility, they can be produced at low cost, even in small batches. They are ideal for applications that require regular maintenance and servicing.
A heat exchanger is a piece of brewing equipment used to raise or lower the temperature of wort or beer. Heat exchangers in breweries are often called "plate heat exchangers" because they consist of a series of plates. The hot liquid flows along one side of the plates and the cold liquid flows along the other side of the plates. The heat exchange occurs between the plates. The most common heat exchangers are found in breweries. Hot wort at about 95°C flows through the heat exchanger and is cooled by cold water and refrigerant flowing in the opposite direction along the other side of the plates.

Takes up a lot of space
Difficult to clean and maintain
In these heat exchangers, each plate has a concave tubular housing that is closed. These plates are arranged in a certain way to form thin rectangular channels to transfer heat throughout the component.
The working fluid flows between these twisted and narrow channels. Gaskets surround the plates of the exchanger and are used to control the fluid flow. These gaskets are arranged in such a way that only one fluid is distributed on one plate and the other fluid is distributed on the other plate.
The cold and hot fluids exchange heat through the plates. The surface area of the plates is larger, so the heat transfer efficiency is higher than that of tube heat exchangers.
With the advancement of modern technology, more powerful also seems to mean smaller. Smaller personal devices, smaller, more versatile manufacturing equipment, and so on. The reduction in space in electrical cabinets increases the risk of hot spots and damage to electrical components, which increases the need for smaller, more efficient cooling solutions.
To work properly, heat exchangers must operate to ensure that high-powered control panels do not overheat. One of the biggest advantages of modern heat exchangers is that they do not rely on more equipment to operate. Therefore, they use less energy and produce little to no pollution compared to traditional cooling methods.
Heat exchangers do not require complex external equipment and are designed to reduce most pollution. Maintenance costs are not as high as air conditioners.
