Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, specifically to a high-efficiency heat exchange water chiller. Background Technology

[0002] A heat exchanger is a device that transfers part of the heat from a hot fluid to a cold fluid. Heat exchangers play an important role in chemical, petroleum, power, food, and many other industrial production processes. In chemical production, heat exchangers are widely used as heaters, coolers, condensers, evaporators, and reboilers.

[0003] Chinese Patent CN217541585U discloses a digital display water-cooled heat exchanger in the field of heat exchanger technology. The heat exchanger includes a heat exchange furnace. A first water inlet pipe runs through one side of the furnace, and a distributor is connected to one end of the first water inlet pipe. Several drain pipes are connected to the side of the distributor, and a transition coil is connected to one end of each of the drain pipes. A heat exchange tube runs through one side of the transition coil, and a water collection tray is connected to one end of the heat exchange tube. A first drain pipe is connected to the side of the water collection tray. An oil inlet pipe runs through the top of the heat exchange furnace, and a digital display screen is installed on the top of the furnace. This invention cools the hot oil by having the heat exchange tubes contact it. The cooled hot oil flows into a loop pipe through the drain pipe. When cooling water enters the water-cooled tank, it cools the hot oil in the loop pipe. Heat sinks further cool the hot oil in the loop pipe, enhancing the heat dissipation effect. The fully cooled hot oil is discharged through an external drain pipe.

[0004] However, the above technical solution has the following shortcomings: hot oil exchanges heat with the coolant in the water-cooled box through the loop pipe in the water-cooled box. The surface of the loop pipe is prone to the adhesion of scale and other foreign objects. On the one hand, it seriously affects the heat exchange efficiency of the water-cooled box. On the other hand, it needs to be cleaned regularly, which is time-consuming, labor-intensive and has high maintenance costs. Utility Model Content
