Description

This invention relates to a heat exchanger and can be used in heat exchangers.

It is known that the shell-and-tube heat exchanger cross section of the neperoiioAOK diameter is made in the end of the ring of elastic material in the form of both with split holes for joining using torshon and the periphery 1Р installed on the periphery with the ability to compensate for thermal deformations C1 3.

The disadvantage of this device is that it does not provide the necessary tightness.

A shell-and-tube heat exchanger is known, which contains radial-longitudinal partitions with slots placed in the shell-and-tube space, and partition walls along the river segment, which are equipped with a parallelo-longitudinal joint Pgap-groove C

The disadvantage of this heat exchanger is low operational reliability.

The purpose of the invention is to increase the level of operational reliability.

This chain is achieved by the fact that, in a shell-and-tube heat exchanger containing spaced in the shell-and-tube space, the longitudinal partitions with cut holes and transverse segment partitions that have a straight and longitudinal connection, are alto-radically welded The overfill is additionally placed, prfiliroyannye sealing elements from elastic metal, mainly from cast iron, located along the perimeter of the shafts and priklyayuschee to segment recurrences 11.

FIG. 1 shows the heat exchanger, general view; figure 2 - sealing element; on fig.Z - heat exchanger, section A-A on .l.

The Yukhukhotrubny heat exchanger contains a bundle of heat exchange tubes 1 fixed in tube plates 2j and partition walls 3 arranged in a shell and tube radial longitudinal section with slots 4 and transverse segment irradiators 5 that have a thorn-groove with radial-longitudinal 3. In addition, in slots x 4 radial-longitudinal partitions 3 are additionally placed profiled sealing elements 6 nz uprzggy metal, mainly made of cast iron, located along the perimeter of the HSC and adjacent to the segment segmented partitions 5.

The heat exchanger operates as follows.

The cooled medium through the nozzle serves in the annular space of the heat exchanger. Moving along its axis, the medium presses the sealing elements 6 to the segmented partitions 5, minimizing overflows. .

An advantage of the present invention is the considerable simplicity in the manufacture of sealing elements, which can be made by turning, for example, a rectangular shape from a cast iron shell, followed by a lock lock. The spring properties of the sealing elements provide minimal gaps between the inside surface of the housing and the sealing element. Moreover, the lock of the upgrade element can be designed in such a way that the leakage of the cooling medium over the lock will be very insignificant. Making the sealing element out of a material having a spring in the properties will prevent refining of the inner surface of the casing, which will significantly reduce the complexity of manufacturing the heat exchanger.

 :;

Thus, the use of the proposed sealing elements will significantly simplify the construction of the heat exchanger, reduce the laboriousness of its manufacture, as well as increase the heat transfer coefficient and operational mobility due to the decrease in overflows in the gaps between the transverse partitions.
