Prices of HTM Brazed Plate Heat Exchangers
HTM Plate Heat Exchanger
An HTM heat exchanger is a device specifically designed for transferring heat between two different fluids. The heat transfer occurs as a result of the temperature difference between the fluids. These heat exchangers are produced in various brands, with HTM and HiWater being among the best choices. The pricing of these heat exchangers is more competitive compared to other brands.
 
HTM Plate Heat Exchanger
HTM heat exchangers are used not only for heating purposes but also for cooling applications. Upon further examination of this essential and widely used device, we will provide a detailed review below.
 
Types of HTM Heat Exchangers
Heat exchangers vary widely in terms of capacity, design, and model. Below, we focus on two of the most common types of heat exchangers:
 
Shell-and-Tube Heat Exchanger
The shell-and-tube heat exchanger is one of the most commonly used models. As its name suggests, it consists of two primary components: the shell and the tubes. One of the fluids circulates through the shell, while the other flows through the tubes. It should be noted that typically the fluid with higher viscosity or solid particles is within the shell, while the fluid with a more liquid-like consistency flows through the tubes.
 
Benefits of HTM Shell-and-Tube Heat Exchanger
Using HTM shell-and-tube heat exchangers offers a range of significant benefits, such as:

Cost-efficiency.
High thermal efficiency due to the extensive surface area between the two fluids.
In case of malfunction, the device can be repaired.
They deliver superior efficiency at high capacities.
And so on.

 
Components of HTM Shell-and-Tube Heat Exchanger
Shell: The shell refers to the body of the heat exchanger, which houses all other components. It is typically made from steel, titanium, etc. The fluid circulates within this shell while other parts are contained inside it.
Tube: The tubes carry the fluid or refrigerant, and are generally made from copper or steel.
Tube Sheet: Tube sheets are utilized in HTM shell-and-tube heat exchangers to fix the tubes in place. Another advantage of tube sheets is that they provide access for mechanical cleaning of the heat exchanger. Based on the tube sheet, two variations of heat exchangers are produced. In one type, two tube sheets are positioned at both ends of the heat exchanger, firmly fixing the shell and the tubes. In the other type, one tube sheet is designed to float freely at one end of the heat exchanger, while the other end is fixed to the shell.
Baffle: This component enhances thermal efficiency and reduces heat loss. It consists of plates positioned between the tubes.
 
HTM Plate Heat Exchanger
The HTM plate heat exchanger consists of several plates placed parallel to each other. These plates are connected in two main ways: using gaskets or welding. Typically, for low capacities, the plates are welded together, while for higher capacities, gaskets are used to connect the plates. It should be noted that the plates in the gasket type can be separated, which is useful in case of plate failure or when adding extra plates to increase capacity. In contrast, welded connections lack this feature, although the long lifespan of these systems helps mitigate this failure. Between the plates, there are channels that create two inlets and two outlets within the heat exchanger: one inlet and outlet for the hot fluid and the other inlet and outlet for the cold fluid. Furthermore, two fluids flow through the channels separately without mixing or coming into direct contact. Heat is transferred through the walls of the plates. The design ensures that the hot and cold fluids alternate across the plates.
  
Benefits of the HTM Plate Heat Exchanger

Its compact design ensures that it occupies minimal space.
Some plate models allow for plate separation and capacity expansion.
They offer high efficiency at low capacities.
The cleaning process for HTM plate heat exchangers is easy.
And so on.

 
 
Classification of Heat Exchangers Based on Fluid Flow Direction
Heat exchangers can be categorized into three main types based on the way fluids circulate within the system:
Parallel Flow: In this configuration, both fluids flow in parallel, adjacent to each other, within the heat exchanger.
Counterflow: In counterflow, the two fluids enter the heat exchanger from opposite directions, flowing parallel but in opposite directions.
Crossflow: In this type of flow, one fluid moves horizontally, while the other flows vertically, and thus they contact with each other indirectly.
 
 
Applications of HTM Plate Heat Exchanger
HTM plate heat exchangers are widely used in various industries due to their high efficiency and quality, including:

Swimming pools
Pharmaceutical industry
Food processing industry
Power generation plants
Textile industry
Oil and petrochemical industry
Marine industry
Residential and commercial heating systems
And so on.

 
Operation of a Shell-and-Tube Heat Exchanger
In this section, we explain how a heat exchanger operates, assuming that two fluids will exchange heat within it. As previously mentioned, the shell-and-tube heat exchanger consists of two main components: the shell and the tubes. Typically, the shell is made of steel, and the tubes inside it are generally made of copper.
 
In this condition, one fluid is located inside the shell, while the other flows through the tubes. Due to the temperature difference between the two fluids, heat flows from the hotter fluid to the cooler one through the tube walls. In fact, every heat exchanger has four entry and exit points: two directed towards the shell for fluid entry and exit, and the other two towards the tubes for the cold fluid’s entry and exit.
 
First, hot water flows into the shell and follows the entire path of the shell. Simultaneously, the cold fluid enters the tubes. When the hot fluid moves through the shell, it transfers its heat to the cold fluid in the tubes as it makes contact with the tube walls.
An essential reason for the hot fluid’s path in a shell-and-tube heat exchanger is the use of plates, that are called baffles. To our knowledge, each tube in the heat exchanger has an inlet known as a turbulator, with the main function of creating turbulence within the tubes. This turbulence prevents any deposition, leading to disturbances inside the shell via the baffles.
 
In general, baffles play a crucial role in heat exchangers by directing the incoming fluid. Moreover, baffles create a turbulent flow, which increases the contact with the tubes.
 
Therefore, it results in more time for heat exchange between the fluid and the tubes.
As described above, the heat transfer rate in heat exchangers directly depends on the extent of fluid contact within the shell and the surrounding surface between the tubes, and this parameter also depends on the number of tubes in the heat exchanger.
