Description

TECHNICAL FIELD

[0001] The application belongs to the field of heat exchangers, and particularly relates to a heat exchange plate with excellent heat conduction performance. BACKGROUND

[0002] A heat exchanger, also known as a heat exchange device, is a device used for transferring heat from a hot fluid to a cold fluid to meet the specified process requirements, and is an industrial application of flow heat transfer and heat conduction.

[0003] Heat exchangers can be classified in different ways, and can be divided into three categories of partition type, mixing type and regenerative type according to the operation process, and can be divided into two categories of compact type and non-compact type according to the compactness of the surface.

[0004] There are many types of heat exchangers, and the most common one is a plate heat exchanger.

[0005] The plate heat exchanger is a high-efficiency heat exchanger composed of a series of metal sheets with a certain corrugated shape. Thin rectangular channels are formed between various plates, and heat exchange is performed through the plates.

[0006] The plate heat exchanger is an ideal device for liquid-liquid and liquid-vapor heat exchange, and has the characteristics of high heat exchange efficiency, small heat loss, compact structure, small footprint, wide application, long service life and the like.

[0007] Under the same pressure loss condition, the heat transfer coefficient is 3-5 times higher than that of a tubular heat exchanger, the footprint is one-third of that of a tubular heat exchanger, and the heat recovery rate can be as high as 90% or more.

[0008] With the development of society, people have higher and higher requirements for plate heat exchangers. In order to meet people's requirements, people improve the structure of plate heat exchangers, and therefore, people invent some heat exchange plates with different functions.

[0009] Through research, the existing heat exchange plates have certain disadvantages in use.

[0010] The existing heat exchange plates are made of metal plates, and cold and hot liquids flow through the upper and lower surfaces of the metal plates for heat exchange. In use, the flow rate of the liquid is fast, and the liquid cannot be fully heat exchanged in use, so the heat exchange effect is poor.

[0011] In the installation process, in order to ensure the sealing effect, the metal plate needs to be accurately aligned, and after alignment, compression is performed. In the use process, the equipment needs to be assisted to calibrate to avoid displacement. The whole process is relatively troublesome, and does not meet people's use requirements. Therefore, people invent a heat exchange plate with excellent heat conduction performance. SUMMARY
