Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor believes that the airtightness of the heat exchange tube can be judged by immersing the heat exchange tube in water and observing the air bubbles. In many cases, the extremely small air bubbles are not easy to be detected by the naked eye, and it is very dependent on judgment; Due to the tension of water, air bubbles may not be generated when there is a slight leak; the air tightness judgment process in the related technology is not accurate

Abstract

The invention relates to a production process of an air cooler. The production process comprises the following steps of cutting an alloy plate, namely assembling to obtain an air cooler shell; manufacturing a heat exchange tube, namely inserting spoilers into U-shaped tubes, expanding the U-shaped tubes, and after tube expansion, connecting the two U-shaped tubes in a welded manner through bent tubes to form the S-shaped heat exchange tube; detecting airtightness, namely taking a standard heat exchange tube and a to-be-detected heat exchange tube, and connecting a pressure difference sensor used for detecting the air pressure difference between the standard heat exchange tube and the to-be-detected heat exchange tube between the standard heat exchange tube and the to-be-detected heat exchange tube; enabling the pressure difference sensor to output a pressure difference; judging whether the to-be-tested heat exchange tube is qualified or not; and assembling the qualified heat exchange tube on the air cooler shell, and installing blades. The process has the advantages that the steps for producing the air cooler are few, the efficiency is high, the standard heat exchange tube is used as a reference object, the output of the pressure difference sensor between the standard heat exchange tube and the to-be-tested heat exchange tube is observed, and due to the existence of the reference object, the influence on testing when the external environment and work are different is reduced.

Description

technical field [0001] The present application relates to the field of air coolers, in particular to an air cooler and a production process. Background technique [0002] The air cooler is a mechanical device that uses the principle of evaporative cooling and has dual functions of cooling and humidifying. It is often used in textile, knitting and other workshops to reduce the temperature in the workshop. Since the air is always introduced from the outside to the room, it is called a positive pressure system. Therefore, it can keep the indoor air fresh, increase the air humidity, force the suspended particles in the air to settle, and play the role of purifying the air. [0003] In the related art, when testing the airtightness of the heat exchange tube of the air cooler, it is usually submerged in water for 15-20 minutes after the heat exchange tube is pressurized to observe whether there are bubbles at the weld of the heat exchange tube. It means that the airtightness of t...
