Abstract

The utility model relates to a non-tube-plate shell-and-tube heat exchanger. According to the non-tube-plate shell-and-tube heat exchanger, a tube unit group which has even surface splicing gaps and is formed in the middle side of an outer sleeve plate in a splicing mode is arranged in the external body of a shell side, and a splicing structural body which forms a channel of a pipe side and the shell side is welded and closed; the tube unit is composed of a metal pipe, splicing elements are arranged at the two ends of the metal pipe respectively, the splicing elements can be arranged in the outer sleeve plate in a splicing mode, splicing gaps of the lateral sides of the splicing elements are even, and the splicing elements are symmetrically welded at the two ends of tubes in pairs respectively to form the tube unit group; the splicing elements are pipe-shaped metal components formed in a casting or stretching mode; the non-tube-plate shell-and-tube heat exchanger is formed by the welding splicing gaps. The non-tube-plate shell-and-tube heat exchanger has the advantages of being simple in structure, economic and practical, and can reduce machining cost.

Description

Without the tube sheet shell-and-tube heat exchanger

Technical field

The utility model relates to a kind of without the tube sheet shell-and-tube heat exchanger, belongs to shell-and-tube heat exchanger manufacturing technology field.

Background technology

Shell-and-tube heat exchanger is heat exchange field equipment commonly used, by tube sheet heat exchanger is divided into tube side and shell side, realize that the medium in tube side and the shell side carries out heat exchange, when making tubulation and tubulation outer wall interval less than 4 millimeters shell-and-tube heat exchanger, the tubesheet holes of processing on the tube sheet is considered the convenient tubulation external diameter that also is greater than of tubulation is installed, tubesheet holes on the tube sheet and the rib thickness between the tubesheet holes will less than 2 millimeters, increase processing tube plate hole difficulty and maybe can't process like this.Therefore, need a kind of new method of research and design to produce this tubulation outer wall interval less than 4 millimeters shell-and-tube heat exchanger.

Summary of the invention

The problem that the utility model exists for above-mentioned prior art and provide a kind of simple in structure, production cost is low without the tube sheet shell-and-tube heat exchanger.

The technical solution of the utility model is as follows:

A kind of without the tube sheet shell-and-tube heat exchanger, it is characterized in that: it is that splicing side surface splicing uniform tubulation unit, gap group in flag is reinstalled in the shell side ectosome, and welded closure is set up the splicing construction body of tube side and shell side passage; The metal tube that the tubulation unit is equipped with respectively splice elements by two ends forms, and several can be assembled in the flag, and the uniform splice elements in side surface splicing gap is symmetrically welded in pairs respectively the tubulation two ends and consists of tubulation unit group; Splice elements is the tubular metallic member of casting or drawing and forming; Welding splicing gap consists of without the tube sheet shell-and-tube heat exchanger.

The utility model has the advantages that simple in structurely, economical and practical, can cut down finished cost.
