In the preferred scheme, the distribution circulation groove, the micro-medium circulation groove and the collection circulation groove on the single plate are integrally formed by punching; when the two plates are butted, a complete distribution channel, a micro heat exchange channel and a collection channel are formed. In addition, two outer heat exchange surfaces of the micro-through plate can be planes or concave-convex surfaces respectively. In one of them preferred scheme, when the inboard punching press of monolithic slab goes out distribution channel, small heat transfer passageway and collection passageway, form the arch on the slab lateral wall, constitute the recess between two adjacent archs in the outside, the unsmooth alternate heat transfer area that increases in outside heat transfer surface.

Meanwhile, the plate can be selected to be a rough surface, so that the heat exchange effect of the medium is further improved.
The micro-through plate is formed by compounding a front plate 1 and a rear plate 2, is generally made of metal materials and can also be made of non-metal materials with high thermal conductivity, when the metal materials are selected, the materials such as stainless steel, carbon steel, copper, alloy aluminum, alloy titanium and the like can be selected, so the micro-through plate is called as the micro-through plate because of two obvious characteristics that 1) the micro-heat exchange channels 5 in the plate are made of thin plates, 2) the micro-heat exchange channels 5 in the plate are micro channels, the diameter of the micro-heat exchange channels is 0.5 ~ 20mm, the micro channels referred to herein are relative, and refer to the caliber of the micro-heat exchange channels 5 relative to the calibers of the distribution channel 1 and the collection channel 2, and the flow media of the micro-through plate include but are2Air and refrigerant, and different media have different viscosities, so the diameters of the channels adapted to the media are different.
On the basis of the technical scheme, the heat exchange efficiency of the second medium is further improved; particularly, the heat conducting part is arranged on the outer side heat exchange surface of at least one plate in the two plates, and the heat conducting part is used for increasing the heat exchange area of the second medium. In a specific embodiment, the heat conducting member is a heat conducting protrusion 21 integrally stamped from a plate, and may be a heat conducting protrusion integrally stamped from any one plate, or a heat conducting protrusion integrally stamped from two plates, as shown in the figure, the heat conducting protrusion 21 is stamped from the rear plate 2; an outer channel for a second medium to pass through is formed between the heat conduction bulge 21 and the other plate; the two ends of the outer channel point to the distribution channel and the collection channel respectively. In the area of the outer channel, the two plates are connected in a sealing mode so that the outer channel and the micro heat exchange channel are independent from each other, namely the two plates need to be connected in a sealing mode along the outer edge of the area of the outer channel, and therefore first media in the micro heat exchange channel are prevented from leaking. In the scheme, the outer channel formed by the heat conduction protrusions 21 is used for the second medium to pass through, and on one hand, the heat exchange efficiency of the second medium is increased by the side wall of the outer channel formed by the heat conduction protrusions 21; on the other hand, because the heat exchange efficiency is improved, the natural convection of the second medium in the outer channel is stronger, the circulation efficiency is higher, and the heat exchange efficiency in the region is further improved. In addition, a further embodiment is that a plurality of heat conducting protrusions 21 are integrally punched on the plate, and the micro heat exchange channels are arranged between two adjacent heat conducting protrusions 21 and inside the micro through plate between the outermost heat conducting protrusion 21 and the edge of the plate.
According to the micro-through plate obtained based on the scheme, at least two micro heat exchange channels are staggered in the built-in micro heat exchange channels 5. So that the fluid medium in the micro heat exchange channel 5 generates turbulent flow and turbulent flow, and the medium generates turbulent flow and turbulent flow, thereby the temperature stratification of the medium is disturbed, and the heat exchange effect is greatly improved. And in accordance with the above principles, improvements to the microchannel plate provide various embodiments, as follows:
in the first scheme, the front plate and the rear plate are respectively provided with a corresponding bulge joint part and a micro medium circulation groove, the bulge joint parts are used as partitions between the micro medium circulation grooves and can break up media in the micro heat exchange channels 5, and the broken-up media are distributed into two adjacent micro heat exchange channels repeatedly. The medium is continuously scattered and continuously converged in the flowing process, and the medium is similar to piers in a river channel to enable water flow to form turbulent flow and turbulent flow. The micro heat exchange channels 5 and the tight fixing points 81 work together to ensure that the medium forms a water curtain shape and is evenly distributed at the inner sides of the two plates. Compared with a common heat exchanger, the medium uniformly distributed in the water curtain shape on the inner side of the thin plate greatly improves the heat exchange effect with the outside. After the protruding joint parts on the front plate and the rear plate are in butt joint, the butt joint points after compounding are arranged in a matrix shape. In one scheme (not shown), the convex joint between the micro heat exchange channels is circular or elliptical, and the medium flow channel between the butt joints is in a peacock tail shape. In another scheme, the convex joint between the micro heat exchange channels is polygonal, and the medium flow channel between the butt joints is in a honeycomb shape. The technical scheme is characterized in that the tiny heat exchange channels on a single plate are in a staggered net shape, and even if the tiny heat exchange channels are combined with another plane plate, the medium flow can form turbulent flow.
In the second scheme, the medium flowing grooves on the butt joint surface of the single plate are not staggered. When the two plates are connected in a composite mode, medium circulation grooves on the two plates are staggered diagonally to form a micro heat exchange channel. As shown in the figure, the diagonal interleaving means that two medium circulation grooves are crossed in a diagonal interleaving manner. In a further preferred embodiment, one media flow channel in one plate is interleaved with two or more media flow channels in the other plate. In the technical scheme, the medium circulation grooves on the two plates are diagonally staggered, the section of a single medium circulation groove can be semicircular, the junction point of the two medium circulation grooves is a rhombic cavity 53 formed by butting two semicircular oblique angles, the space of the rhombic cavity is larger than that of the medium circulation groove, and the two medium circulation grooves converge at the place. From this simultaneously, the medium circulation groove is the inner groovy, then protruding region between two adjacent medium circulation grooves is narrow plane, when two slab docks, narrow plane also is the laminating department 8 (welding point) of diagonally staggered constitution above-mentioned bellied face, preceding slab and the bellied 8 butt joints (welding) of laminating department of back slab form inseparable fixed point 81, and this inseparable fixed point 81 and rhombus chamber all around (upper and lower direction and left and right sides direction) equal interval setting, the effect that its produced is that two medium circulation grooves converge in the rhombus intracavity, then distribute to two adjacent small heat transfer passage 5 in by bellied inseparable fixed point 81 again, it is in turn with the reposition of redundant personnel to produce to converge, promote turbulent effect. In the above scheme, the medium flow channel is in a multi-segment zigzag shape (as shown in the figure, a W shape) or a corrugated shape, and the selection of the medium flow channel as the multi-segment zigzag shape should consider the limitation of the number of the zigzag angles of the multi-segment zigzag lines, which affects the medium flow resistance in the small heat exchange channels 5 on one hand, and reduces the area of the fluid heat exchange weakening area formed on the left and right side ends (the ends of the non-distribution channels and the collection channels) of the plate, i.e. the flow channel resistance and the number of the flow channels of the internal small heat exchange channels 5 are slightly different from those of the flow channels in the. In general, the angle degree of the medium flowing channel needs to be reasonably set in implementation. When the media channel is chosen to be corrugated, the amplitude and wavelength of the corrugations should be defined. Compared with the scheme (I), the scheme has the characteristics that the medium circulation grooves arranged on the single plates are not staggered, and only when two single plates are compositely connected, the formed micro heat exchange channels are staggered.
The embodiment relates to a micro-through plate which adopts an integrally formed and compounded scheme, simplifies the process, and improves the quality and the reliability. The inner side medium flow channel in the micro through plate consists of a distribution channel, a collection channel and mesh-shaped crossed micro heat exchange channels, and the micro heat exchange channels scatter media in the flow channel to form turbulent flow and turbulent flow. The path lengths of a plurality of medium channels from the medium inlet to the medium outlet are similar, and the small heat exchange channels which are uniformly distributed on the whole plate surface in a meshed and staggered mode further ensure that the medium fully utilizes the heat exchange surface, so that the maximization of the heat exchange effect is facilitated.
In addition to the above technical problems to be solved, the micro through plate also has the following characteristics;
1, at inboard machining distribution channel of monolithic slab, small heat transfer passageway, collection channel recess, form the arch on the slab lateral wall, constitute the recess between two adjacent archs in the outside, the unsmooth alternate outside heat transfer area that increases in the outside has promoted the heat transfer effect with external by a wide margin.
2, two plates of the micro-through plate are thin plates or ultrathin plates, no welding point is arranged outside, and the micro-through plate of nonferrous metal does not need post electrophoretic spraying and other treatments, thereby greatly improving the heat transfer speed and the heat exchange effect, saving energy, protecting environment and reducing the material consumption.
