Description
Technical field
The present invention relates to field of heat exchangers, and in particular to a kind of compact heat exchanger structure of heat exchanger channels arranged crosswise.
Background technique
The cold and hot side runner of printed circuit board heat exchanger is that the gold with different geometry microchannels slot is respectively adopted
Metal thin plate forms cold and hot side runner layering alternately cloth in such a way that cold and hot side heat exchanger plates are alternately superimposed and are connected using diffusion
The compact parallel connection micro-channel heat exchanger set.Printed circuit board heat exchanger have it is compact-sized, heat exchange area per unit volume is big,
The features such as bearing capacity is strong, and operating temperature range is wide.The microchannel structure of its heat exchanger plates surpasses particularly suitable for less viscous gas
Critical fluids heat exchange.In order to optimize fluid heat transfer performance, flow resistance is reduced, it is micro- to propose different heat exchanger plates in succession both at home and abroad
Channel design.Wherein, most typically Z-type microchannel, S type microchannel and fin type microchannel.Microchannel structure enhances
Fluid flow-disturbing enhances fluid heat transferring, and the corresponding channel resistance of S type and fin type microchannel is also substantially reduced.
Printed circuit board heat exchanger mostly uses greatly cold side and the alternately laminated arrangement of hot side heat exchanger plates at present, in cold and hot effluent
The heat exchange process of fair current or convection current is formed in the respective fluid layer of body.It is larger that above-mentioned arrangement can guarantee that cold and hot side liquid has
Heat exchange area, but the microchannel structure of cold and hot side brings apparent frictional resistance to be promoted to two side liquids.
When fluid viscosity coefficient is higher, flow resistance and pressure drop in microchannel will be significantly increased, and strongly limit this
The scope of application of cramped construction heat exchanger.Simultaneously because also there is very high requirement in microchannel to the cleannes of fluid, so that double
The compact heat exchanger of side microchannel cannot be used directly for industrial waste gas, and the fluid of the entrained particles impurity such as flue gas of refuse burning changes
Hot field.When being applied to fluid heat transfer field, in order to expand application range, need that printed circuit board heat exchanger is overcome to use
Along journey flow resistance, big, fluid cleanliness requires the problems such as harsh to the cold and hot alternately laminated arrangement bring of side microchannel plate.
Summary of the invention
The technical problems to be solved by the present invention are: compact heat exchanger in the prior art cannot be used directly for Industry Waste
The problem of gas, the fluid heat transfer field of the entrained particles impurity such as flue gas of refuse burning, is, and it is an object of the present invention to provide a kind of heat exchanger channels are handed over
The compact heat exchanger structure for pitching arrangement, being designed by reasonable structure can be effectively applicable to that heat transfer coefficient is low, heat-transfer surface
Long-pending demand big low viscosity fluid and viscosity is high or there are the high efficient heat exchanging between particle entrainment fluid, is effectively directly applied to industry
