Description

[Detailed description of the invention] Heat exchanger elements and their usage The present invention is based on the following features: 1 group arranged parallel to each other in a plane or several thousand times F parallel to each other within the frame of the machine; The present invention relates to a heat exchanger element having a tube.

Heat exchangers can be manufactured in a variety of configurations depending on their use. Become In their applications, heat exchangers are assembled from individual parts, and they are also assembled from other parts. In this application, it is manufactured by assembling a series of completed elemental parts.

From German Patent No. 144.700, a group of substantially parallel tubes Heat exchanger elements are known which consist of a machine frame having a heat exchanger required Depending on the size, weld the appropriate number of elements and joint pipes and connecting pipes to them. installed and assembled, and configured so that the heat exchange medium passing through the tubes flows as desired. It is something to do. Additionally, for a complete heat exchanger, the element assembly must be Provide a watertight and pressure-tight housing to contain the pipes, or match all pipes in the correct order. It is necessary to connect each other.

It is an object of the present invention to provide a completely completed and a large number of top and bottom plate members. It is possible to assemble between The purpose of the present invention is to provide a heat exchanger element or element.

This object, according to the present invention G, is indicated in the following claim 1 and therein. This is achieved by configuring seven heat exchangers. A packing material is used between the packing surfaces, and a large number of Completely completed heat exchanger by erecting diagonal 1 to elm 1 according to the present invention can be obtained. All inlet and outlet openings shall be located in the top or bottom plate member. is possible. The medium flowing through the tubes is completely isolated from the medium flowing between the tubes. , a chamber provided at the end of the tube is used to guide the medium into and out of the tube. According to the method, a dividing plate is inserted and installed between the pipes, and this allows the pipe to pass through and through it. The medium flowing around the tube can be guided in a zigzag flow around the tube. It is possible.

The heat exchanger element according to the invention may be configured as claimed in claim 2. Divide all the tubes into two or more groups by to flow through other tube groups or to allow the medium flowing through each tube group to This makes it possible to ensure that they are not the same. According to this configuration, the heat exchanger The element can be used for multiple purposes.

Furthermore, the heat exchanger element according to the invention is configured as claimed in claim 3. If so, the element is split into two element parts completely separated from each other. In this case, the possible applications of the heat exchanger are further expanded. One part is used as the boiler or evaporator of the fresh water production machine, and the other part is used as the condenser. In this case, for example, waste heat from a ship's engine can be passed through one group of pipes. However, cooling water, such as seawater, can be passed through the other group of tubes to condense the steam onto the tubes. I can do it.

The heat exchanger element according to the invention may be configured as claimed in claim 4. It is also possible. By providing a large number of direction change rooms, one pipe group or multiple pipes can be Groups of tubes can be arranged in a series of communication configurations, in which case the heat exchanger can e.g. It is convenient for many applications, such as when cooling the medium with cooling water flowing outside the pipe. Ru.

The invention also provides the advantage of multiple heat exchanger elements as defined in claim 5. It also relates to usage. The effect of the present invention in this regard is, for example, in a heat exchanger such as a fresh water production machine. Manufacturing and sizing of the machine can be done by simply assembling the required number of elements. The fact is that it can be done in a simple way. Furthermore, for example, if it is a fresh water production machine , it is not necessary to take the trouble to enclose it and provide a watertight and pressure-resistant outer wall member.

This is because such outer wall members are attached to the machine frame of the heat exchanger element. This is because it has already been formed. Furthermore, one of the two divided parts of the element If one is used as a boiler and the other is used as a condenser, the structural height of the freshwater production machine is can be reduced to almost half of the conventional value.

The fresh water producing machine to which the present invention is applied is particularly suitable for marine use as described in claim 6. It is suitable for Unlike many known freshwater machines that do not produce This is because an installable freshwater production machine can be provided. In particular, ships employed today In terms of structure, there is a strong demand for a freshwater production machine with a small construction height and high production rate. Ru.
