Description

Heat Exchanger Structure

This work is about a "heat exchanger structure", especially a heat exchanger that uses high temperature for welding of metal plates.

During the operation of the unit, some of the units need to be heated by fluid, and some must be cooled to adapt to the operating conditions of the unit. The heat exchange process is usually completed by a heat exchanger, and the so-called heat exchanger refers to energy. A device for exchanging heat between two fluids, so for the normal operation of the unit, the existence of the heat exchanger is absolutely necessary, and at present, the plate heat exchanger is the most common.

The plate heat exchanger is composed of high-efficiency heat transfer corrugated plates and a frame. The plates are clamped by bolts between the two fixed plates before and after the frame. Many flow channels are constructed, and the plates are sealed with rubber gaskets.

However, the above-mentioned conventional structure still has the following problems in practical application: (1) The plates of the heat exchanger need to be aligned one by one before they can be locked by passing through bolts, so It is quite time-consuming and labor-intensive to install; (2) the rubber gaskets need to be installed between the said plates for sealing, so the use cost is high, and the installation steps are also complicated; (3) the rubber gaskets It is not resistant to high pressure and acid and alkali, which will severely limit the use of the heat exchanger (cannot be used in high pressure or chemical fields).

In addition, there is another shell-and-plate heat exchanger in which the plates are stitched by laser welding. A rubber gasket is also installed inside the plates, so as to pass through all the plates after the plates are stitched. Install the rubber gasket described above to prevent leakage.

However, the above-mentioned other conventional structure still has the following problems in practical application: (1) The plate is stitched by laser, so the processing cost is high, and the stitch welding requires The whole circle is welded, so the heat exchanger also has the problem that the processing speed is too slow; (2) the plates cannot withstand high pressure after welding, and the rubber gaskets cannot resist acid and alkali, which makes the heat exchanger unable to withstand high pressure. Use is also severely limited.

Therefore, how to develop and improve the shortcomings of the above-mentioned conventional heat exchangers is actually the goal of the relevant industry. In view of this, the creator has thought about the idea of creation, so he has many years of experience. Design, after many discussions and trial samples, and many revisions and improvements, this creation is launched.

Conventional heat exchangers are slow to assemble, have high processing costs, and cannot withstand high pressure and acid and alkali, which are the technical problems to be solved.

The present invention provides a heat exchanger structure, the heat exchanger includes several metal plates, each of the metal plates has two end surfaces, and at least one of the end surfaces is provided with a fluid flow channel. The end surface of the flow channel provides another metal plate for abutting, so that the at least two metal plates can be smoothly combined with their end surfaces. After joining, the metal plates are combined into a whole by high-temperature welding, so that the metal plates do not need to be locked or welded to form a complete heat exchanger for use. At least one fluid input channel and at least one fluid output channel are reserved, and the fluid input channel, the fluid output channel and the fluid flow channel provided in the heat exchanger are connected and conducted, so that the fluid can flow from the The fluid input channel is sent into the inside of the heat exchanger to fully flow through the fluid flow channel, and then sent out from the fluid output channel, so as to use the continuous flow of the fluid to heat up or cool down the applied unit. Therefore, a heat exchanger structure can be obtained.

(1) The present invention provides a heat exchanger structure. The heat exchanger is formed by directly welding metal plates, so the trouble of locking the metal plates one by one can be omitted during assembly, and there is no need to do welding slowly. , so that the production of the heat exchanger can be more efficient and the processing cost is low.

(2) The present invention provides a heat exchanger structure, the metal plates of the heat exchanger are welded into one body, so that the heat exchanger can reach a seamless state after welding, so there is no need to install an additional seal inside the heat exchanger. In addition to being able to withstand high pressure, the heat exchanger is more resistant to acid and alkali, so as to greatly improve its application range.

(3) The present invention provides a heat exchanger structure, and there is no need to install a rubber gasket inside the heat exchanger, so there is no problem of the fluid leakage caused by the aging of the rubber gasket, so that the heat exchanger can be more durable, and No need for frequent repairs and maintenance to replace the rubber gasket.
