Description

A heat transfer jacket structure

technical field

The utility model relates to the technical field of heat transfer jackets, in particular to a heat transfer jacket structure.

Background technique

Due to the low investment, short production cycle, convenient automatic management and stable beer quality, the open-air fermenter has many advantages. Equipped with cooling jacket. Most of the current beer fermentation tanks use various jackets welded with thin plates on the outer surface of a thick stainless steel plate of about 4 to 8 mm, and a cooling medium is passed into the jacket to realize the function of beer fermentation. The inner surface of the fermenter is smooth and flat, and the outside of the tank is insulated to reduce the loss of cold energy.

Since a large amount of heat energy is generated during beer fermentation, it is necessary to rapidly cool the beer with the cooling medium in the jacket in the shortest possible time. However, in the existing jacket, due to the thicker tank wall and the large thermal resistance of stainless steel, the heat transfer effect is poor. As the volume of the fermenter becomes larger and larger, it is difficult to meet the technological requirements of beer fermentation.

In order to improve the heat transfer efficiency, the applicant's patent application number CN200420037437.4 (publication number CN2750279Y) and the Chinese utility model patent "built-in laser welding heat transfer jacket structure" and the patent application number CN201310151188.5 ( The Chinese invention patent "A Honeycomb Jacketed Fermentation Tank" with publication number CN104120053A) discloses a heat transfer jacket structure, which includes two plates, on which there are certain The welding area arranged in a geometric shape, while the other non-welding areas are in a convex arc shape, so that the inner cavity section is in a concave-convex honeycomb shape.

Specifically, as shown in FIG. 1, an interlayer 11 is formed between the two boards 1, and a plurality of welding spots 12 for welding the two boards 1 together are arranged in the interlayer 11. The two boards 1 Adjacent peripheries of the interlayers are welded to each other to form a weld 13 for sealing the periphery of the interlayer 11. The plate body 1 on the outer side has a liquid discharge port 14 that communicates with the interlayer 11. When the jacket stops working, the bottom layer of the jacket structure The part of the channel 111 lower than the discharge port cannot be completely drained, resulting in the presence of fluid accumulation. As the water volatilizes, the concentration of chloride ions will gradually increase. With the repeated work and stop of the jacket, the chlorine in the bottom channel 111 will The ion concentration gradually increases, and the chloride ion concentration reaches a certain proportion, which will corrode the bottom weld seam and increase the risk of leakage.
