Description

Technical Field

[0001] This utility model relates to the field of condenser technology, and more specifically, to a gradient heat transfer corrosion-resistant condenser. Background Technology

[0002] A condenser is a heat exchange device that cools a gas or vapor and converts it into a liquid. Its core function is to remove heat from the medium through heat transfer, thereby achieving a phase change. The condenser absorbs heat from the vapor by cooling the medium, causing its temperature to drop and liquefy. This process follows thermodynamic principles, with heat transferred from the high-temperature vapor to the low-temperature medium, ultimately achieving a vapor-to-liquid phase change.

[0003] For example, application number CN202223576677.9 discloses a corrosion-resistant condenser. By setting several equidistantly distributed fins on the cooling tube body, the heat dissipation area of ​​the cooling tube can be increased, thereby improving the heat exchange efficiency of the cooling tube. Since the fins on each cooling tube are equidistantly distributed, when two adjacent cooling tubes are parallel to each other, the fins on the adjacent two cooling tubes can be staggered to make full use of the space inside the condenser, so that the cold fluid can fully contact the cooling tube, thereby improving the heat exchange efficiency of the equipment. In the prior art, the temperature gradient distribution is uneven. Among them, the air-cooled condenser causes local overheating or overcooling due to uneven air flow, and the condenser body is susceptible to corrosive media.

[0004] Therefore, a gradient heat transfer corrosion-resistant condenser is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a gradient heat transfer corrosion-resistant condenser to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a gradient heat transfer corrosion-resistant condenser, comprising a frame, a condenser tank, and a heat exchange assembly. The condenser tank is fixedly mounted on the upper end face of the frame, and the heat exchange assembly is provided in the inner cavity of the condenser tank. The heat exchange assembly includes a first end cap, a heat exchange tube, and a second end cap.

The outer diameter surface of the heat exchange tube is laser-etched with sharkskin micro-rib grooves, and the inner diameter surface of the heat exchange tube is connected with a cylindrical grid. The inner cavity of the heat exchange tube has a double-layer structure.

[0009] Preferably, a first heat insulation plate is provided on the side of the first end cap away from the heat exchange tube, and a second heat insulation plate is provided on the side of the second end cap away from the heat exchange tube, with the heat exchange tube passing through the first and second heat insulation plates laterally.

[0010] Preferably, the bottom end face of the condenser tank is provided with a drain port, and the top end face of the condenser tank is provided with a liquid inlet. The liquid inlet and the drain port are connected through a second cavity.

[0012] Preferably, the drain port and the inlet port are respectively connected to an external coolant output pipe and an external coolant input pipe, and the exhaust port and the inlet port are respectively connected to an external gas output pipe and an external gas input pipe.

[0013] Preferably, the heat exchange tubes transversely penetrate the first end cap, the second end cap, the first heat insulation plate, and the second heat insulation plate. The heat exchange tubes are arranged uniformly and symmetrically, and the aperture size of several groups of heat exchange tubes gradually decreases radially. The frame, condenser tank, first end cap, heat exchange tubes, second end cap, cylindrical grid, first heat insulation plate, second heat insulation plate, drain port, inlet port, exhaust port, and air inlet port are all coated with anti-corrosion coatings.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] Compared with existing technologies, this gradient heat transfer corrosion-resistant condenser, in its use, allows gas to be cooled as it passes through the condenser tank. The pore size of the heat exchange tubes gradually decreases radially, resulting in radiative heat dissipation and thus achieving gradient heat transfer. Furthermore, the condenser tank and its internal components are protected against corrosion with an anti-corrosion coating, and the heat exchange tubes are made of pure copper, further enhancing corrosion resistance.
