A heat exchanger is a piece of machinery that lets two or more liquids of varying temperatures pass through one another for either heating or cooling purposes. Liquid line heat exchangers include a range of industrial-grade pieces of equipment designed for a different varieties of applications. Some of the more common types include:
Tubular Heat Exchanger
A tubular heat exchanger is a huge cylinder with pipes within it. The liquid or refrigerant in tubular heat exchangers refrigerators flows through the pipes, while other fluids flow through the outer cylinder. This is also referred to as concentric heat exchangers.
Plate Heat Exchanger
Plate heat exchangers are industrial-grade pieces of equipment that use thin plates to transfer heat between liquids. They are compact and save energy but require regular maintenance and cleaning. The main advantage of plate heat exchangers is that they can be made into gaskets on the perimeter of the plates. This means that on the non-heat transfer surfaces, cold water can be used to bring down the temperature required to go through portions of the system that don't need to be heat transferred. On heat transfer areas, the refrigerant can be used. Therefore, it can vary as to how much heat transfer is needed. Gaskets can be used to cut costs and reduce energy losses.
Screw Heat Exchangers
A screw heat exchanger is a thermal transmission device that can continuously carry two different fluids in a spiral channel, hence realizing the counterflow heat exchange. The structure of the screw heat exchanger includes a stationary element and a movable element. The stationary element includes the external cylindrical body and the stationary screw with a spiral blade. The movable element includes the spindle and the movable screw with a spiral blade.
Liquid heat exchangers are available in a variety of models that offer different specifications to meet industrial needs. It is important to note that the heat exchanger specification will vary depending on the type of machine.
Design Parameters
The design parameters include length, width, height, as well as pressure and temperature ratings. The liquid exchanger typically has the maximum temperature of 270°C to 370°C. Its pressure rating can reach up to 50 bar.
Material
Liquid heat exchangers' main body is usually made of carbon steel or stainless steel. Aluminum is also an option because it has good thermal conductivity. Stainless steel liquid exchangers are known for their corrosion resistance, extending the longevity of the exchangers.
Connections
A liquid heat exchanger has a variety of connection types including flange, nipple, welding, threads, etc. A flange liquid transfer connection provides easy assembly and disassembly. This connection is ideal for industrial applications where frequent equipment maintenance is required.
Operating Environment
Material choice is crucial to the functioning of the liquid exchanger in the industry. Frequent contact with corrosive liquids or high levels must use liquid exchangers. The heat exchanger withstands harsh environments. It also avoids operational failure or safety risks.
Because there are so many varieties and styles, buyers need to check the manufacturer's instructions. They can gain a thorough understanding of proper usage and maintenance as well as key precautions for the equipment. What follows is some general advice for the maintenance procedure.
Liquid line heat exchangers are essential components used to transfer heat between two liquids. Below are some industry applications in which liquid line heat exchangers are used.
Food Processing Industry
Food manufacturing companies use liquid heat exchangers to pasteurize fluids such as milk, juice, sauces, and other liquid food items. By doing so, the liquid line heat exchanger helps the company control the growth of bacteria in perishable liquids to extend their shelf lives. Additionally, liquid heat exchangers are used in food processing companies to extract essential oils and flavors from organic matter. They are also used to gelatinize starch and hydrolyze carbohydrates.
Chemical Industry
In the chemical industry, liquid line heat exchangers are used in different chemical processing applications, such as polymerization, reaction facilitation, and condensation.
Some chemical compounds must be precipitated or crystallized at specific temperatures and pressure levels. Therefore, liquid line heat exchangers control temperature precisely to achieve the desired chemical reactions and compound formations.
Pharmaceutical Industry
Pharmaceutical companies depend on liquid line heat exchangers to achieve sanitation, which is paramount when manufacturing drugs and medicines. Also, the devices are used to control temperature as chemical compounds are reacting or changing states within the manufacturing process. Heat exchangers liqud lines also assist in drying equipment and extraction units to regulate the flow of fluids.
HVAC Systems
Liquid line heat exchangers are evaporators found in HVAC systems. They absorb heat from the surroundings into refrigerants that flow through the device. The refrigerants are then cooled through condensers until the heat is dispersed into the external environment. Additionally, liquid line heat exchangers are used to dehumidify and cool indoor air spaces. They may also be used to recover waste heat from industrial processes to heat liquid streams.
Energy Sector
Power generation companies use liquid heat exchangers to cool and condense working fluids such as steam in the condensers of steam turbines. Cooling of the turbine’s condenser allows a vacuum to form that facilitates the expansion of steam within the turbine, thus improving the efficiency of power generation.
Application requirements:
Business buyers should consider their application needs first when selecting heat exchangers. They need to consider what fluids the exchanger will deal with at what temperatures and pressures. Also, the quantity and type of fluids must be taken into consideration. For instance, in the food processing business, fruit juice processors may require liquid sugar heat exchangers for concentrated liquid sugar. Therefore, buyers should determine the specific working environment and functional requirements of the equipment.
Heat transfer efficiency:
Heat transfer efficiency is another vital factor when choosing heat exchangers because this efficiency directly affects the overall performance of the whole equipment. Business buyers can refer to the design and technical parameters of the equipment, such as the type of heat transfer surfaces and the arrangement of the fluids.
Materials and durability:
Commercial users need to ensure the choice of heat exchanger materials and their durability can withstand long-term use and potential harsh environments. Buyers need to consider the maintainability and usability of the equipment by checking for any rapid wear and tear at the same time.
Installation and connection:
Business buyers should ensure that the heat exchanger can be properly installed and connected to other devices in the production line. They need to evaluate the installation dimensions and connection methods of the equipment to avoid potential technical problems during the later stages of use.
Energy efficiency and operating cost:
In commercial applications, operating costs and energy efficiency are crucial. Buyers need to choose heat exchangers with high energy utilization efficiency and low operating costs to reduce the overall production expenses of the enterprise.
Compliance with standards and certifications:
Business buyers need to ensure that the heat exchanger they choose complies with relevant industry standards and possesses the required certifications to guarantee the quality and safety of the equipment.
Q1: How big are liquid line heat exchangers?
