Abstract
The invention discloses a mechanical hollowed-out printed circuit board type heat exchanger achievement method in the field of heat exchangers. Metal cover plates are additionally arranged between hollowed-out metal heat exchange plates; heat exchange flow channels are machined on the metal heat exchange plates; hollowed-out inlet and outlet flow channels are machined on the metal cover plates; after the metal cover plates and the metal heat exchange plates aresmoothly flushed to each other, inlets and outlets of the heat exchange flow channels of the metal heat exchange plates are covered with the inlet and outlet flow channels on the metal cover plate; and the hollowed-out metal heat exchange plates and the metal cover plates on the two sides form a complete closed flow channel. The method solves the problem that because cold fluid and hot fluid in the prior art are directly mixed, a flow channel cannot be formed; PCHE cost can be remarkably reduced; and machining is fast.
Description
Technical field
What the present invention relates to is a kind of device of technical field of heat exchangers, and specifically the printed circuit board heat exchanger implementation method of wearing engraved by a kind of machinery.
Background technology
Printed circuit board heat exchanger (PCHE) is that a kind of heat transfer property is excellent, high efficiency compact heat exchanger.PCHE is stacked together by the diffusion bonding of polylith metallic plate, and a surface of metallic plate has many grooves, and different fluids flows in the groove of different metal sheet surfaces, and heat exchange occurs.PCHE has high unit volume exchange capability of heat.
The runner of traditional PCHE metal sheet surface is processed by the chemical etching of complexity, and this makes PCHE cost very high.Machining is adopted to produce PCHE runner, be expected to reduce costs low, raising process velocity, but directly adopt machining PCHE metallic plate that PCHE can be caused to lose efficacy, main cause is: 1) adopt the machining process processing flow channel such as laser cutting or grinding tool punching press PCHE metallic plate can be carved and wear, after causing the stacked diffusion bonding of metallic plate, cold fluid and hot fluid directly mixes, and makes PCHE inner fluid cannot heat exchange and losing efficacy; 2) PCHE metal heat-exchange plate surface runner is divided into import and export, flow manifold and heat exchange runner three part, the metal heat-exchange plate of machining can make the import and export of PCHE, flow manifold and heat exchange runner three part all engrave to wear, cause not engraving the part of wearing between adjacent two heat exchange runners to come off from metal heat-exchange plate, thus cannot runner be formed.
By finding the retrieval of prior art, Chinese patent literature CN1784583A, publication date 2006 ?06 ?07, discloses the heat exchanger core of a kind of PCHE.PCHE in this technology is stacked together by the diffusion bonding of polylith metallic plate, and a surface of metallic plate has the semicircle groove that many cross sectional shapes are radius 0.5mm.Flow different fluids in the runner on adjacent two pieces of metal heat-exchange plate surfaces, between adjacent two blocks of metal heat-exchange plates, heat exchange occurs.But this technology can not solve the two problems that machining PCHE metallic plate causes, reason is: 1) existing technology processes traditional semi-circular recesses by electrochemistry half-etching, as shown in Figure 1.If the heat exchanger plates worn adopting the quarter of machining can not form closed runner after directly stacking together and causing the stacked diffusion bonding of metallic plate, fluid leaks at the runner of breakage, different fluid interpenetrates, and makes PCHE inner fluid cannot heat exchange and losing efficacy.2) all engraved by machinery due to the import and export of heat exchanger plates and flow manifold and wear, not engraved by machinery entity that the part of wearing and heat exchanger plates main body be not connected and coming off from heat exchanger plates main body between runner, can not form complete runner, as shown in Figure 2.
Chinese patent literature CN201964552U, day for announcing 2011.09.07, disclose a kind of double-sided radiation end heat exchanger, it by the netted passage 2 of double-side radiation panel 1, radiant panel internal flow, netted passage forms plate 3, adhesive layer 4 forms, can pass into the mediums such as water in pipe network and realize heat transmission, the heat exchanger of unit are has larger exchange capability of heat.But this technology does not belong to printed circuit board heat exchanger category; And this technology can only be used for air and liquid heat exchange, the heat exchange between two strands of liquid can not be realized, cause this technology can not meet the field of current PCHE application.
Summary of the invention
The present invention is directed to prior art above shortcomings, the printed circuit board heat exchanger implementation method providing a kind of machinery to engrave to wear, solve cold fluid and hot fluid of the prior art directly mix and the problem of runner cannot be formed, thus meet the application requirement of PCHE, reduce the cost of PCHE, and processing is quick.
The present invention realizes especially by following technical scheme:
The present invention engraves the printed circuit board heat exchanger implementation method of wearing by relating to a kind of machinery, the heat exchange runner worn is engraved by processing on metal heat-exchange plate, on metal cover board, the import and export runner worn is engraved in processing, after metal cover board is alignd with metal heat-exchange plate is smooth, import and export runner on metal cover board is covered with the import and export part of metal heat-exchange plate heat exchange runner, and the metal cover board engraving metal heat-exchange plate and the both sides of wearing forms complete closed runner.
After described metal cover board aligns with metal heat-exchange plate is smooth, the import and export runner on metal cover board is covered with the import and export part of metal heat-exchange plate heat exchange runner.Fluid is directly communicated with from the import and export of metal cover board with the heat exchange runner of metal heat-exchange plate, eliminates import and export and the flow manifold link of metal heat-exchange plate.Owing to only machined the heat exchange runner engraved and wear in metal heat-exchange plate, heat exchange runner does not carry out machinery and engraves the part of wearing and can directly be connected with metal heat-exchange plate both sides, can't depart from metal heat-exchange plate main body.
The present invention engraves by relating to a kind of machinery the printed circuit board heat exchanger worn, comprise: at least two-layer metal heat-exchange plate being respectively used to cold fluid and hot fluid and the metal cover board be arranged between metal heat-exchange plate, wherein: metal heat-exchange plate is provided with some and closed engraves percolation road, and metal cover board is provided with corresponding import and export runner.
Described metal heat-exchange plate and metal cover board interlaced arrangement, and be stacked to one piece of heat exchanger core by diffusion bonding each other.
Engrave starting point and the terminal in percolation road described in the position of described import and export runner is right against, after described metal cover board aligns with metal heat-exchange plate is smooth, make the import and export runner on metal cover board be covered in the import and export part of metal heat-exchange plate heat exchange runner.
The metal cover board diffusion bonding of engraving metal heat-exchange plate and the adjacent both sides of wearing forms runner, and the fluid in the runner of different metal heat exchanger plates is by the metal cover board heat conduction generation heat exchange between metal heat-exchange plate.
Technique effect
Compared with prior art, the present invention adopts the runner of machining PCHE metal heat-exchange version, avoid the electrochemical etching process adopting cost higher, fluid is directly communicated with from the import and export of metal cover board with the heat exchange runner of metal heat-exchange plate simultaneously, eliminates import and export and the flow manifold link of metal heat-exchange plate.Owing to only machined the heat exchange runner engraved and wear in metal heat-exchange plate, heat exchange runner does not carry out machinery and engraves the part of wearing and can directly be connected with metal heat-exchange plate both sides, can't depart from metal heat-exchange plate main body.
