Abstract

A heat exchanger for exchanging heat of fluids having different temperatures, comprising: at least one smooth heat exchanging plate; at least one high temperature heat exchanging plate; and at least one low temperature heat exchanging plate stacked in an alternating sequence, wherein an inlet of high temperature fluid and an outlet of high temperature fluid are disposed in order to pass a high temperature fluid through each said high temperature heat exchanging plate, and an inlet of low temperature fluid and an outlet of low temperature fluid are disposed in order to pass a low temperature fluid through each said low temperature heat exchanging plate, wherein said high temperature heat exchanging plate and said low temperature the heat exchanging plate comprising a high temperature channel and a low temperature channel, wherein said channels have a length extending in a flow direction of said fluids and a side wall of each said channel has a symmetric wavy pattern with the center line of said channel.

Description

technical field [0001] Chemical engineering involves a heat exchanger for exchanging heat of fluids with different temperatures. Background technique [0002] So far, there have been reports on the development of microchannel heat exchangers. When compared to normal sized channels, microchannels provide higher heat transfer performance than normal heat exchangers, such as shell and tube heat exchangers and plate and frame heat exchangers. This is because the flow in microchannels can transfer heat more quickly from the channel walls into the fluid, the fluids in each channel have similar flow cross-sectional temperatures, the heat transfer surface area is higher than normal channels of the same volume, and the channels in the relatively low pressure drop. However, microchannels have some disadvantages that lead to application limitations. For example, because the passageway is narrow, it is easy to block. In particular, when used for heat exchange of fluids with very dif...
