Abstract

Disclosed is a shell-and-tube heat exchanger, which comprises two or more than two U-tube heat exchangers; wherein the U-tube heat exchanger comprises a shell side inlet, a tube side inlet, a shell side outlet, a tube side outlet, a tube seal head and a shell side cylinder. The shell-and-tube heat exchanger is characterized in that not less than two U-tube heat exchangers are connected in series to form a novel shell-and-tube heat exchanger. By adopting the combination of multi-level single-tube side, the shell-and-tube heat exchanger has the advantages of novel, rational and compact structure, convenient manufacturing, large effective area and high heat exchange efficiency.

Description

Shell-and-tube heat exchanger

Technical field

The utility model relates to a kind of tubular heat exchanger, is specifically related to a kind of a kind of novel shell-and-tube heat exchanger that adopts a plurality of U type heat exchange of heat pipe serial connections to constitute.

Background technology

Tubular heat exchanger is to use heat-transfer equipment the most widely during present chemical plant produces, but often again based on multitube journey heat exchange mode, so there is following shortcoming: heat exchange efficiency is low; Flow velocity is slow easily to be stopped up; Diameter reaches the heat exchange inequality, and diameter is little but heat exchanger is oversize, uses inconvenience.

The utility model content

The problem that runs in order to overcome in the background technology, the utility model have adopted multistage single tube journey combination, a kind of novel shell-and-tube heat exchanger that just adopts a plurality of U type heat exchange of heat pipe serial connections to constitute.

The technical solution of the utility model realizes by following means: a kind of shell-and-tube heat exchanger, comprise two or more U type heats exchange of heat pipe, wherein U type heat exchange of heat pipe comprises shell side import, tube side import, shell side outlet, tube side outlet, channel closure and shell-side cylinder.It is characterized in that having the U type heat exchange of heat pipe serial connection that is no less than two to constitute a kind of novel shell-and-tube heat exchanger.Wherein, the outlet of the tube side of a U type heat exchange of heat pipe is connected by channel closure with the tube side import of another U type heat exchange of heat pipe.And the outlet of the shell side of a U type heat exchange of heat pipe is connected with the shell side import of another U type heat exchange of heat pipe.

The utility model is new reasonable and compact, and is easily manufactured, and effective area is big, the heat exchange efficiency height.

Supplemental instruction

Fig. 1. the shell-and-tube heat exchanger of prior art is a U type heat exchange of heat pipe structural representation.

Fig. 2. the structural representation of the utility model embodiment.

Wherein: 1. shell side import; 2. tube side import; 3. shell side outlet; 4. tube side outlet; 5. channel closure; 6. shell-side cylinder.

Specific embodiments

Below in conjunction with accompanying drawing the utility model is further described:

As shown in Figure 1, the shell-and-tube heat exchanger structure of prior art is that U type heat exchange of heat pipe structure comprises shell side import 1, tube side import 2, shell side outlet 3, tube side outlet 4, channel closure 5 and shell-side cylinder 6.As shown in Figure 2, the utility model has adopted multistage single tube journey combination, a kind of novel shell-and-tube heat exchanger that just adopts a plurality of U type heat exchange of heat pipe serial connections to constitute.Wherein, the tube side of U type heat exchange of heat pipe outlet 4 is connected by channel closure 5 with the tube side import 2 of another U type heat exchange of heat pipe.And the shell side of U type heat exchange of heat pipe outlet 3 is connected with the shell side import 1 of another U type heat exchange of heat pipe.Make reasonable and compact in structure, easily manufactured, effective area is big, the heat exchange efficiency height.
