Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a printing plate heat exchanger having an intermediate plate,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate-type heat exchanger, and more particularly, to a plate-type heat exchanger including a structure capable of increasing a heat exchange area as a result of which heat exchange capacity can be increased.

In the case of a shell-and-tube type heat exchanger according to the prior art, the size of the housing must be sufficiently large enough to accommodate even if the thermal expansion is disadvantageous in terms of the heat transfer area per unit volume, There was a problem requiring very large and heavy equipment.

Particularly, in the case of a heat exchanger applied to an LNG carrier, it is preferable that the heat exchanger has a certain level of heat exchange capacity and at the same time has a small volume.

Therefore, the conventional shell-and-tube type heat exchanger is very difficult to be utilized for an LNG ship or the like because of its large volume and heavy weight.

Also, the conventional shell-and-tube type heat exchanger is not easy to maintain and has a problem in that a required capacity of a crane or a handling device for moving the apparatus must be increased.

In order to solve these problems, a plate-type heat exchanger has been manufactured and used.

FIG. 1 is a partially cutaway perspective view showing a conventional plate-type heat exchanger according to the prior art, and FIG. 2 is a perspective view showing the plate-type heat exchanger shown in FIG.

FIG. 3 is an exploded perspective view of the plate-type heat exchanger shown in FIG. 2. FIG. 4 is an exploded perspective view of the plate-type heat exchanger shown in FIG. A discharge tube, an upper plate, and a lower plate.

The built-in header design is advantageous because the required thickness of the header is very large when applying a press plate heat exchanger (PCHE) to a high-pressure system.

When using built-in headers, the distance between the headers and the distance between the header and the outer wall should be more than a certain distance according to the allowable stress and system pressure.

In order to satisfy such a condition, in the case of the conventional plate type heat exchanger according to the related art, as shown in Fig. 3, each component manufactured in a specific shape and size is welded.

Specifically, the A fluid inlet header 13 and the A fluid outlet header 14 constituting the printing plate heat exchanger 10 according to the related art are mounted on the header upper plates 13-1 and 14-1 And the lower header plates 13-2 and 14-2 are welded together.

In the case of the plate-type heat exchanger 10 shown in Figs. 1 to 3, the size of the housing is required to be sufficiently large to accommodate even if thermal expansion occurs due to the heat transfer area per unit volume, There is a problem that very large and heavy equipment is required in order to process the waste water.

Therefore, since the size of the heat exchanger is large and the weight is heavy, the maintenance is not easy and the required capacity of the crane or the handling device for moving the device must be increased.

Furthermore, when the width of the channel plate is increased in order to improve the heat exchange efficiency, the heat exchange capacity is increased but the flow rate is lowered and the heat exchange efficiency is lowered.

To solve this problem, a plurality of platen plate heat exchanger modules can be connected in parallel.

However, in this case, the connection piping and the resulting heat loss and pressure loss are generated.

Accordingly, there is a need for a technique capable of solving the problems of the above-mentioned prior art.
