Description

Technical Field

[0001] The utility model belongs to the technical field of heat exchangers, and particularly relates to a disc heat exchanger. Background Art

[0002] A coil heat exchanger is a common heat exchange device. Its working principle is mainly based on the principle of enhanced heat transfer. By using copper tubes as the heat transfer part and making these tubes spirally floating in the shell, it achieves efficient heat transfer. It has the characteristics of small size, high heat transfer coefficient, and strong anti-scaling ability. When the equipment is working, the coil is completely immersed in the shell-side water. Since the coil generally uses highly elastic tubes, the coil can float back and forth during operation, generating micro-frequency vibrations, which makes the shell-side water easily reach a turbulent state, exchanging heat with the heat medium in the tube bundle, thereby improving heat exchange efficiency.

[0003] The spiral pipe inside the coil heat exchanger is long. During long-term use, various substances will be deposited in the pipe, such as colloids, particulate matter and other impurities, causing pipe blockage, which in turn affects the heat exchange effect and requires cleaning. However, the spiral pipe of the coil is long, and the cleaning process is more troublesome. There are always places that are not cleaned in place, and the cleaning process is more time-consuming and labor-intensive. When the coil heat exchanger is in use, there is a problem that there is no design to filter the liquid entering the coil. For this reason, this application proposes a disc heat exchanger.
