1.Partition wall heat exchanger
Partition wall heat exchangers are two fluids with different temperatures flowing in the space separated by the wall surface. The heat conduction between the wall surface and the convection of the fluid on the wall surface, and the two fluids exchange heat. Partition wall heat exchangers include shell and tube, sleeve and other types of heat exchangers. Partition wall heat exchanger is currently the most widely used heat exchanger.
2.Regenerative heat exchanger
Regenerative heat exchangers transfer heat from high-temperature fluids to low-temperature fluids through heat storage bodies composed of solid matter. After the heat medium reaches a certain temperature by heating the solid matter, the cold medium is heated by the solid matter to achieve the heat. Purpose of delivery. Regenerative heat exchangers include rotary and valve switching types.
3. Fluid connection indirect heat exchanger
The fluid connection indirect heat exchanger is a heat exchanger that connects two surface heat exchangers with a heat carrier circulating in the heat exchanger. The heat carrier circulates between the high-temperature fluid heat exchanger and the low-temperature fluid, and receives the high-temperature fluid. Heat, the heat is released to the cryogenic fluid in the cryogenic fluid heat exchanger.
4.Direct contact heat exchanger
Also known as a hybrid heat exchanger, this type of heat exchanger is a device that directly contacts two fluids and mixes with each other for heat exchange, such as a cold water tower and a gas condenser.
5.Double heat exchanger
Equipment that has two types of heat exchange methods: steam-water surface indirect heat exchange and water-water direct mixed heat exchange. Compared with steam-water surface indirect heat exchange, it has higher heat exchange efficiency; compared with steam-water direct mixed heat exchange, it has higher stability and lower unit noise.
