Definitions

  • Chemical engineering relates to a heat exchanger for exchanging heat of fluids having different temperatures.
  • microchannel heat exchanger When compared to the normal size channels, the microchannels provide a higher heat transfer performance than normal heat exchanger, such as a shell and a tube heat exchanger and a plate and a frame heat exchanger. This is because the flow in microchannels can transfer heat from a channel wall into fluid faster, fluids in each channel have similar flow cross section temperatures, a heat transfer surface area is higher than normal channel at the same volume, and a pressure drop in the channel is relatively low.
  • the microchannels have some disadvantages that lead to limitation for application. For example, it is easily to be clogged because the channel is narrow. Especially, when being used for heat exchanging of fluids having highly different pressure, the permanent deforming can be happened.
  • the character of the channel of the heat exchanger is important to the heat transfer performance and the overall strength of the heat exchanger.
  • the character of the channel is a parameter to indicate the possibility in fabrication and the arrangement of the channel together. Therefore, there have been attempts continuously to develop the character of the channel in order to increase the performance of the heat exchanger and overcome the limitations previously said.
  • US20040031592 disclosed the heat exchanger comprising microchannel for the heat exchanging of three or more fluid streams, wherein the wall of said channel was fiat with fins disposed in order to increase the heat changing surface area.
  • the installation of said fins increased a fouling rate inside the heat exchanger. Therefore, this reduced the heat transfer performance and increased the pressure drop of the heat exchanger.
  • said design might have a problem when using with high pressure fluid, leading to a limitation.
  • US4516632 disclosed the microchannel heat exchanger comprising the slotted heat exchanging sheets and unslotted heat exchanger sheets stacked in an alternating sequence, wherein the slotted heat exchanging sheet was placed in 90 degree with respect to one another in an alternating sequence in order to form a cross-flow configuration of fluids having different temperatures. Nevertheless, said flow configuration did not give a high heat exchanging performance.
  • EP 1875959 disclosed the forming process of an emulsion with the installation of the heat exchanger comprising the microchannel heat exchanging plate stacked in an alternating sequence, wherein said channel was designed like a snake shape. This made two flowing patterns in said channel: a counter-current and a co-current. However, said channel design leads to easily clogging of the contaminants and was more difficult to clean comparing to the one flow direction path from one side to another side.
  • US8858159 disclosed a gas turbine comprising cooling channels for the low temperature air to flow pass and reduce heat of blades in the gas turbine, wherein said cooling channels were equipped with curved in and out ribs and the pedestals between each pair of ribs in order to increase the heat transfer performance.
  • said pedestals between each pair of ribs might increase the pressure drop of the heat exchanger which was the limitation when applying to the heat transfer between fluids with highly different pressure or fluids with high viscosity.
  • US20100314088 disclosed the heat exchanger comprising plates consisting of micrcochannels stacked in an alternating sequence. Said plates were designed to be curved and said microchannels were set into non-symmetric wavy form making parallel channel along the flow direction of fluids. The total length of direct portion and curve portion was set to be constant. However, said patent did not disclose the suitable parameters of said wavy channel such as width size, curve radius, etc.
