Embodiment Construction

[0016] see Figure 1-Figure 3 , the specific embodiment adopts the following technical scheme: it includes a box body 1 and a casing 2, and the two ends of the box body 1 are provided with an oil inlet 1-1 and an oil outlet 1-2, and the two ends of the side of the box body 1 are respectively There are water inlets 1-3 and water outlets 1-4. The shell 2 is arranged outside the box body 1. It also includes a reverse spirally wound tube bundle 3. Several layers of reverse spirally wound tube bundles 3 are concentrically arranged inside the box body 1.

[0017] The odd-numbered layers of the several-layer reverse spirally wound tube bundle 3 are opposite to the spiral winding direction of the even-numbered layers, that is, the odd-numbered layers are clockwise, and the even-numbered layers are counterclockwise; otherwise, the odd-numbered layers are counterclockwise, and the even-numbered layers are is clockwise.

[0018] The reverse helically wound tube bundle 3 is an ordinary t...

Abstract

The invention relates to a reverse helically-coiled tube type cooler and belongs to the technical field of convection heat exchange. An oil inlet (1-1) and an oil outlet (1-2) are arranged on the two ends of a box (1), a water inlet (1-3) and a water outlet (1-4) are arranged on the two ends of the side surface of the box (1) respectively, a shell (2) is arranged on the outer side of the box (1), a plurality of layers of reverse helically-coiled tube bundles (3) are concentrically arranged in the box (1); the helical winding directions of the odd number layers and the even number layers of the reverse helically-coiled tube bundles (3) are opposite; the flowing state of fluid is changed, and thus strong turbulence effect is formed. Moreover because the length of the reverse helically-coiled tube type cooler is 4-6 times as long as the length of the shell, heat exchange medium inside and outside the heat exchange pipe bundles can be subjected to complete heat exchange. The pressure bearing capacity is high, the structure is compact, the heat stress can be slowly released, the heat exchange coefficient is large, the heat exchange efficiency is high, and the cooler has considerable flexibility, adaptability and reliability.

Description

Technical field: [0001] The invention relates to the technical field of convective heat exchange, in particular to a reverse spiral wound tube cooler. Background technique: [0002] In the field of convective heat transfer, the selection of energy-saving and consumption-reducing coolers has become an important indicator for engineering inspection and acceptance. Traditional shell-and-tube coolers have problems of decreasing heat transfer efficiency year by year, large maintenance, difficult condensate recovery, infrastructure investment and power failure. Consumption and other issues. Invention content: [0003] The object of the present invention is to provide a reverse spiral wound tube cooler, which changes the flow state of the fluid and forms a strong turbulent effect, and because the threaded tube reverse spirally wound tube bundle can reach four to six times the length of the shell, it can Make the hot and cold medium fully exchange heat inside and outside the heat...
