Embodiment Construction

[0031] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0032] Such as figure 1 As shown, a high-efficiency double-pass heat exchanger according to the present invention includes a double-pass heat exchanger composed of an upper tube box 1, a lower tube box 2, a shell 3, and a heat exchange tube bundle 4. The lower tube box 2 is equipped with Partition partition 5; such as Figure 2-Figure 5 As shown, the heat exchange tube bundle 4 is composed of a plurality of tube plates 8 and multiple rows of flat heat exchange tubes 7 vertically arranged on the tube plates 8, and the cross section of the flat heat exchange tubes 7 has Concave-convex structures that are evenly spaced.

[0033] Such as Figure 4 As shown, the flat-mouth heat exchange tube 7 is made of a stainless steel plate after stamping, folding in half, and butt welding.

[0034] Such as Figure 5 As shown, the tube sheet 8 is a split struc...

Abstract

The invention relates to an efficient double-travel heat exchanger. The efficient double-travel heat exchanger comprises a double-travel heat exchanger body composed of an upper pipe box, a lower pipebox, a shell and a heat exchanging pipe bundle; a pass partition plate is arranged in the lower pipe box; the heat exchanging pipe bundle is composed of a plurality of pipe plates and a plurality ofrows of flat opening heat exchanging pipes vertically arranged on the pipe plates; and the cross sections of the flat opening heat exchanging pipes are provided with concave-convex structures at equalintervals in the length direction. The efficient double-travel heat exchanger is high in heat transfer efficiency, high in heat resistant capacity, safe and reliable, compact in structure, and capable of increasing the space utilizing rate, and lowering civil construction and equipment manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a high-efficiency double-pass heat exchanger. Background technique [0002] Traditional shell-and-tube heat exchangers are widely used and have various structural forms, which can meet the use of various working conditions, but there are still disadvantages such as heavy weight, large volume, easy scaling, and low heat exchange efficiency. With the continuous increase of the scale of production equipment of petrochemical enterprises, in order to improve the economic benefits and equipment operation efficiency of oil refining and chemical enterprises, the development of a heat exchanger with a small footprint and high efficiency and energy saving is one of the current research directions of petrochemical production. Contents of the invention [0003] The invention provides a high-efficiency double-pass heat exchanger, which has high heat transfer efficiency, strong heat ...
