Heat exchanger convenient to replace

Abstract

The invention discloses a heat exchanger convenient to replace. The heat exchanger comprises a heat exchange box frame, wherein a heat exchange pipeline is arranged on the inner side of the heat exchange box frame; an integrated heat exchange inlet is formed in the bottom of one end of the heat exchange pipeline; an integrated heat exchange flow opening is formed in the top of the other end of theheat exchange box frame; a protection box is arranged at one end of the front surface of the inner side of the heat exchange box frame; a cotton piece is wound in the protection box; and a pull rod is arranged at one end of the cotton piece. The cotton piece capable of being automatically wound is arranged on the heat exchange box frame of the heat exchanger, the cotton piece can be pulled out tocover the heat exchange pipeline, the heat exchange pipeline in the heat exchange box frame is protected through the cotton piece, the pipeline is prevented from being collided, abraded, cracked or broken, a heat preservation cover is arranged on the outer side of the heat exchange box frame in a covering manner, the inner side of the heat preservation cover is filled with a polystyrene foam layer, through the effect of the polystyrene foam layer, the heat preservation and heat insulation effects can be achieved, heat in the heat exchanger is prevented from being dissipated, the heat exchangeefficiency is not affected, and practicability of the device is improved.

Description

technical field [0001] The invention belongs to the technical field of heat exchangers, and in particular relates to a heat exchanger which is easy to replace. Background technique [0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, also known as a heat exchanger. Heat exchangers play an important role in chemical, petroleum, power, food and many other industrial productions. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc., and are widely used , Finned tube heat exchangers are usually composed of partitions, fins, seals, and deflectors. Fins, deflectors and seals are placed between two adjacent partitions to form an interlayer, which is called a channel. Such interlayers are stacked according to different fluid methods and brazed into a whole to form a plate bundle. The plate bundle is a plate. The core of the fin heat exchanger, together with the necessar...

Problems solved by technology

[0004] The purpose of the present invention is to provide a heat exchanger that is easy to replace, so as to solve the existing heat exchanger that is easy to replace proposed in the above-mentioned background technology. Fluid, and the main body of the heat exchanger is usually screwed and fixed at the working place by bolts, which makes the heat exchanger more convenient to disassemble and replace, and has better sealing performance. However, when the heat exchanger is used and installed, due to heat exchange The heat exchange in the device is exposed. Before installation and transportation, if the heat exchange pipes are bumped, it is easy to cause damage to the pipes, affecting the efficiency and safety of heat exchange.
