Abstract

The utility model discloses a unit type heat exchanger which comprises an inner liner and a casing enwrapping the inner liner, wherein the wall of the inner liner forms a waviness shape, and one end of the inner liner is provided with a detachable hand hole cover; a liquid inlet and a liquid outlet of the inner liner, a liquid inlet and a liquid outlet of the casing are respectively arranged at both ends of the inner liner and at both ends of the casing, and the liquid direction in the inner liner and the liquid direction in the casing are opposite. The utility model has the advantages of compact and simple structure, larger capacity of the inner liner, high heat exchange efficiency and convenient installation and maintenance.

Description

Unit heat-exchanger

The utility model relates to a kind of modular interchanger that can be used for the multiple fluid heat exchange.

Existing heat exchanger kind is more, as shell-and-tube (shell and tube, coiled); Jacket type (bushing type, cover rod-type); Board-like (flat, corrugated plate dst, spiral plate type) or the like,, all there are some such or such shortcomings in these heat exchangers, for example: though jacket type is simple in structure, be easy to produce, be convenient to maintenance, but heat transfer efficiency be low, bulky; The volume of shell-and-tube is relatively littler, produce, cleaning is more convenient, but heat transfer efficiency is low; Though board-like have a higher heat transfer efficiency, structure is yet compact, and complex structure is produced, maintenance is very difficult, and the water storage deficiency.

The purpose of this utility model be for provide a kind of simple and compact for structure, heat exchange efficiency is high, be convenient to the unit heat-exchanger producing and maintain.

Main technical schemes of the present utility model is: it comprises the shell of inner bag and ring bag inner bag, it is corrugated that wall of inner container is, inner bag one end has dismountable hand hole cover, the fluid import and export of inner bag, the fluid import and export of shell is located at the two ends of inner bag and shell respectively, and makes the direction of flow in inner bag and the shell opposite.

Owing to adopt said structure, the fluid heat-exchange time in the utility model is prolonged, and has effectively improved heat exchange efficiency.The structure of inner bag, shell increases the inner bag volume and the very simple compactness of structure, is convenient to produce and maintenance.And open hand hole cover and just can clear up whole inner bag, make maintenance work also very convenient.

Fig. 1 is the structural representation of an embodiment of the present utility model;

Fig. 2 is the scheme of installation of the porch deflector of fluid inlet among Fig. 1.

As shown in Figure 1, unit heat-exchanger of the present utility model comprises the shell 2 of inner bag 1, ring bag inner bag 1, it is corrugated that wall of inner container is, one end of inner bag 1 has dismountable hand hole cover 8, the fluid import and

export

7,5 of inner bag 1, the fluid import and export 4,3 of shell 2 is located at the two ends of inner bag 1 and shell 2 respectively, and makes the direction of flow in inner bag 1 and the shell 2 opposite, wherein flow in the chuck of heat-transfer fluid between shell 2 and inner bag 1, heated fluid flows in inner bag 2.As shown in Figure 2, be provided with deflector 6 in the porch of fluid inlet 7, deflector 6 and horizontal line angle are between 30 °-60 °, and preferably 45 °, deflector 6 makes fluid produce rotation with the bellows wall of inner bag, can prolong heat exchanger time, improves heat exchanger effectiveness.
