[0002] A heat exchanger is a device used to transfer heat between two different fluids. It is often used in industries such as industry, mining, chemical industry, electric power, and metallurgy. Condenser is a common heat exchanger that is used to convert gas or steam into liquid. It is usually composed of a cooling medium (such as water or air) and a heat exchange surface. It lowers the temperature of the gas or steam, causing it to lose energy and condense into liquid. When using this equipment, the internal pipeline structure needs to be cleaned regularly to avoid blockage.

[0003] There is a heat exchanger cleaning device available on the market that uses a plastic hose to pass into a delivery pipe and then uses water flow to transport water into the delivery pipe to clean dirt. However, since there are multiple delivery pipes inside the heat exchanger, this device requires the operator to hold the plastic hose and insert it into each delivery pipe in turn to clean the heat exchanger, which is cumbersome and time-consuming.
