Problems solved by technology

In the past, fixed tube-sheet heat exchangers were used, and bare tubes were used as the main heat exchange components. Due to their large size and large footprint, and one set cannot meet the heat exchange needs, the investment cost increased, and tube heads often appeared. The cracking phenomenon causes the water side to infiltrate into the gas side, pollutes the clean gas, and makes the next process unusable, affecting production and causing losses
Now there are also some coolers with finned tubes, which are only suitable for cooling compressed air with a temperature of about 100 degrees and several thousand Pa, and there is really no better way to cool high-temperature and high-pressure gases. In this case There is an urgent need for a cooler for high temperature and high pressure gas with good cooling effect, small size and low investment

Embodiment Construction

[0018] The cooler described in this application consists of a shell 1, a finned tube 2, a tube plate 3, a water box 4, a connecting pipe, a flange and other components. The housing 1 is divided into three parts, namely an air inlet part 11, an air outlet part 12 and a heat exchange part 13. The air inlet part 11 and the air outlet part 12 can be designed in the shape of a prism, preferably a quadrangular truncated structure. An air inlet 14 is provided at the end of the air intake part 11, an air outlet 15 is provided at the end of the air outlet part 12, and finned tubes 2 are arranged transversely on the heat exchange part of the shell 1, and both ends of the finned tubes 2 are welded to the tube plate 3, There is a water box 4 at the welding place between the finned tube 2 and the tube plate 3, and the water box 4 is connected through the connecting pipe 5, and the two ends of the connecting pipe 5 are composed of two mouths, one is the water inlet 51, and the other is the w...

Abstract

The invention relates to a fin cooler. The cooler comprises a shell, wherein the shell is divided into an air inlet part, an air outlet part and a heat exchange part; an air inlet and an air outlet are respectively formed in the ends of the air inlet part and the air outlet part; the heat exchange part of the shell is transversely provided with a fin tube; the two ends of the fin tube are welded with a tube plate; and a water box is arranged in the welded position of the fin tube and the tube plate, and is communicated through a connecting tube. The cooler can cool compressed air with a temperature of 129 DEG C and a pressure of 0.25 MPa. As the compressed air and a fluid are vertically staggered, the cooling effect is better.

Description

technical field [0001] The invention relates to a cooler, in particular to a finned cooler. Background technique [0002] There are many fields of application of coolers, the scope of application is extremely wide, and the role is very important. In grain deep processing enterprises or pharmaceutical industries, coolers are needed to cool the air and keep the air clean. In the past, fixed tube-sheet heat exchangers were used, and bare tubes were used as the main heat exchange components. Due to their large size and large footprint, and one set cannot meet the heat exchange needs, the investment cost increased, and tube heads often appeared. The cracking phenomenon causes the water side to infiltrate into the gas side, pollutes the clean gas, and makes the next process unusable, affecting production and causing losses. Now there are also some coolers with finned tubes, which are only suitable for cooling compressed air with a temperature of about 100 degrees and several tho...
